1, abrasive abrasive industry overview

1 Classification and characteristics of abrasive abrasive products

Referred to as abrasive grinding tools, grinding with a Bonded Abrasives, coated abrasives and superhard abrasive three major series, have their own characteristics, independent existence, have their own strengths. Bonded Abrasives Bonded Abrasives is to use abrasive (grinding material) and the binding agent made of a certain shape and a certain capacity grinding tools.

Bonded Abrasives marks Example: Shape size of abrasive particle size binder hardness of the organization 35M/SGB/T2485 shape of 300 × 50 × 75 code-named types of abrasive grain-bonded abrasive grinding hardness of the work of the Organization of Supreme conditions where the standard rate of abrasive technology No. In addition to the maximum working speed and abrasive technical conditions where the standard numbers, the other for the consolidation of the abrasive characteristics.

Abrasive particle size refers to the thickness of abrasive size, abrasive grinding consolidation with the next series of standards, which are based on the seven characteristics of the 1998 National Standardization Technical Committee abrasives published by the Chinese machinery industry standards in each of the provisions of . Here is the consolidation of abrasive hardness of the external force, the combination of binder and abrasive strength, according to the thickness of particle size were used blasting hardness and Rockwell hardness measurement.

Hardness of sub-super-soft (super-soft one, super-soft 2), soft (the soft one, soft 2), in the soft (the soft one, the soft-2), medium (medium 1, medium 2), medium hard (the hard one , the hard-2, the hard-3), Hard (hard one, hard 2), super-hard (super hard one, hard 2), etc. 7 large levels of 15 small-class. Bond refers to the consolidation of the various types of abrasive products and abrasive binder bonding material. Bonded Abrasives usually ceramic, resin, rubber, magnesite four categories of binding agent. These four binder with ceramic binder grinding the largest proportion.

VITRIFIED main materials are clay, feldspar, loess, quartz stone composed of different abrasive, for different purposes and different system of law (Pouring or suppress) different ceramic binder. Phenolic resin binder is mainly the type of resin, powder resins and liquid resins sub-two categories, also based on the different laws and different uses of the system is divided into a variety of resin binder.

Rubber binder currently used man-made SBR, buna rubber and liquid rubber three categories, according to the different system of law and uses of different and divided into a variety of rubber binder. Magnesite binders main materials are magnesium oxide and magnesium chloride composed of two materials, mainly used for fine-grained abrasive for fine-processing purposes.

Various combinations of agents of the code is as follows: Name of bonding agent bonding agent bonding agent, code-named ceramic V resin-bonded rubber binding agent B Bond R magnesite Mg (3) organization: the organization refers to the consolidation of the volume occupied by abrasives in the abrasive , by weight% to that.

Usually organizations in abrasives signs are not displayed, while the manufacture formula based system, self-control to Arabic numerals, ie the number of smaller, more loose organization, namely, consolidation of abrasive in the ratio of the less abrasive the contrary, the greater the number of The more compact organization, representing the ratio of the more abrasive. Usually the organization from No. 0-12, No. 13 organizations..

Coated Abrasives Coated Abrasives is the abrasive binder to adhere to the abrasive substrate deflection, also known as flexible abrasives. Coated Abrasives has nine characteristics: substrate types - Material handling - Abrasive types - abrasive particle size - sand-planting density - binder types - bond strength - shape - size.

Diamond Abrasives Diamond Abrasives is caused by employing superabrasive diamond or cubic boron nitride abrasive made of, the Department of abrasive another major series. Several characteristics of super-hard abrasive and marked with the following: concentration, binding agent, grain size, abrasive grade, abrasive layer thickness, diameter, total thickness, diameter, shape code above features and markings are in accordance with ISO 1998 National Abrasives Technical Committee of China published by the Chinese machinery industry standard requirements for each standard on the concentration: the organization and consolidation of abrasive roughly the same number, but in super-hard abrasive should be marked in the sign.

The so-called super-hard abrasive concentration is the volume per cm3 in the number of grams contained in the super-hard abrasive to% numbers indicate the concentration of code is as follows: Code abrasive concentration (g/cm3) the concentration of 250.2225% 500.4450% 750.6675% 1000.88100% 1 501.32150% on the integration of agent: refers to a combination of super-hard abrasive agent used in class. Bond code is as follows: binder resin bond agent, code-named B metal binding agent M vitrified bond V.

2, abrasive abrasive industry History

New China abrasives industry from scratch, from scratch, from small to big, after half a century of self-reliance, hard work, and gradually establish a relatively independent and complete abrasives R & D, manufacturing, testing systems, especially in the reform and opening up after 10 years, has made more rapid development in the nineties of the last century, our abrasives industry and the gap between the advanced world level has been greatly reduced.

However, as the world's materials technology, the mechanical processes and technologies, as well as the rapid development of scientific instruments, in the turn of the century period of time, the rapid development of foreign abrasives industry, new technologies, new products, new processes are emerging; while the period of China's industrial abrasives industry is in a management system reform, enterprise, transforming themselves, the stage of the restructuring of industrial organization, the original industrial layout has been disrupted, the new market order is exploring the establishment of industrial development and technological progress at a standstill 1:00 state, making the already narrow gap has been quickly widening.

At present, the world's economic development orientation and the regional economic structure is in great flux. Driven by economic globalization, China's modernization and the world increasingly accelerated process of economic integration, the country's overall technological level and increasing the quality of the state to enhance the comprehensive strength rapidly.

Our abrasives manufacturing enterprises to adapt to global economic integration and expansion of domestic demand, the opportunities and challenges, corporate reorganization, restructuring, reform, transformation and the pace of adjustment of product structure has also been rapid development of increasingly sharp increase in the degree of internationalization .

Founding 60 years, abrasives manufacturing enterprises in China have made rapid development, and gradually formed a complete product range, with a certain overall strength of abrasives production system. Formed a joint venture with multinational companies and domestic companies and small part of the mainly high-end abrasives manufacturing enterprises, and part of the former state-owned large and medium-sized state-owned enterprises restructuring and developed rapidly in recent years, large-scale private and characteristics of private and high-end enterprise-based abrasives manufacturers, and in small and medium private enterprises mainly low-end production of three levels of abrasives manufacturer.

At present annual production capacity abrasives already have a large scale, most of the product areas of excess capacity. General speaking, half a century, China abrasives production has been great development, but with the international advanced enterprises compared to the top abrasives, there is still a gap.

(1) of the overall process and there is a certain gap between the level of equipment. Abrasives manufacturing enterprises in China After years of development, a number of key enterprises and equipment level has been greatly improved, some technology and equipment level to achieve convergence with the international first-class level of modernization, but the overall level of overall technology and equipment, abrasive grinding and international with advanced enterprises still lags far behind, especially in the production process, automation and equipment, and technology aspects of information integration throughout the plant.

(2) In the past with international competitiveness is mainly low-tech, value-added products smaller, while the core of large, high-tech products, competitiveness is still relatively low. Bonded abrasive products in particular. But in recent years, conditions have greatly improved, in the abrasive part of the area has been part of our high-quality product supply domestic and international markets.

(3) The output of low efficiency. Advanced countries, Abrasives manufacturing enterprises Zengjiazhishuai largely in between 50% to 150%, the lowest is also more than 30% abrasives manufacturing enterprises in China is only 5 to 20%, differ greatly. Labor productivity gap between the larger and most enterprises in China is only 5 ~ 300 thousand yuan / person, only the equivalent of advanced foreign companies to 10 ~ 15%. Low economic efficiency.

(4) abrasives product technology, high-end product performance and new product R & D, with foreign advanced level there is a considerable gap.

(5) business-to-market, rapid reaction capability poor. China Abrasives new product development cycle for an average of 18 months, the product life-cycle of 10 to 15 years. The Foreign realized "three three", namely, product life-cycle of three years, the product trial period of 3 months, the product design cycle for 3 weeks.

(6) enterprise scale structure is irrational. From industry in terms of organizational structure, our abrasives manufacturer unreasonably combination of enterprise scale, large enterprises and enterprise but not strong, leading role of industry, little, small businesses, minor professionals, collaboration is poor, companies in the market competition into a a stalemate. In particular, the strength of large enterprises are still not achieve the scale of operation and group operation, it is difficult to compete with multinational companies to go abroad.

In general terms, our abrasives industry, the existing more than 1,200 enterprises in 2007 reached 61.45 billion yuan industrial output value at current prices compared with 2006, an increase of 40.3%; to achieve sales income of 60.48 billion yuan, an increase of 40.2%, is in a period of rapid growth. But because of their own R & D capability is weak, lower barriers to entry in recent years has been to imitate, copy, based on the development and expansion of inefficient consumption of a large number of valuable resources and energy, with the international advanced level there is a large gaps, mainly in:

① high-tech products can not meet the market demand, dependence on imports; low-end generic products, there is a structural surplus, resulting in backlogs, the outstanding purchase price, and price wars.

② industry-wide production capacity has reached a certain scale, but the actual production capacity of more dispersed, small-scale enterprises with low economic efficiency.

③ technology development capacity is weak, self-owned intellectual property products and technologies to small, there is no grasp of product development initiative. ④ less product variety, low-tech, manufacturing process data a lack of rigorous testing and verification, can not maintain constant product quality is stable.

⑤ abrasives industry, the domestic brand-name gold content is low, less likely to have an international brand.

Today, ordinary Chinese abrasives, producing about 180 million tons. 2007 exports of 1.11 million tons, with an average 484 U.S. dollars / ton; import of 90,000 tons, with an average 750 U.S. dollars / ton. Circulation pattern in the world industry, national as brown corundum and silicon carbide production and export powerhouse. At present countries have begun to implement an active industrial policy, fiscal policy, improve resource and energy use costs and other means to restrict the brown corundum and silicon carbide-based high-energy consumption, high pollution, the development of common abrasives, has begun to bear fruit.

4, abrasives industry, development environment

(1), the inevitable product of the industrialized countries

Abrasives as a manufacturing, oil exploration, mining survey, the areas of material processing and alternative processing an indispensable tool, as the industry's "teeth", as a country's economic development, the basic foundation for the industry to alleviate the "bottleneck "constraints, the bound is committed to stimulate and promote the economy as a whole, such as manufacturing, oil exploration, mineral prospecting, materials processing, and other leading industries. Today is the world's industrial powers are all above-mentioned areas of power, China should take the rich, powerful way, to develop more industry is the inevitable choice. This will bring about the development of abrasives great opportunities for development.

(2), the general trend of economic globalization,

Production and operation of cross-regional, but also embodied in the social consumption of cross-regional. Should be comprehensive, in-depth understanding of this trend on China's economy. International Abrasives multinational companies in China, bringing capital, advanced technology, management experience and new business ideas, injected vitality into China's economy.

The past two years, with China's accession to WTO, Foreign Cooperation in the emergence of new phenomena, such as the introduction of technical negotiations more difficult; the newly established foreign-invested enterprises or foreign-owned a marked increase in the proportion of absolute control. These phenomena are related to the current domestic and foreign economic situation changes associated, it should be cause for concern as early as possible.

Therefore, since the economic interests of both sides, management strength, political beliefs and ideological and cultural differences, our abrasives manufacturing enterprises in China with the international economic integration in the process of co-operation will both opportunities and risks, domestic enterprises must keep a sober mind, the spirit of good will and common development, pragmatic cooperation and development.

Sales of products and services, globalization of the market as a whole is relatively low competitiveness of manufacturing enterprises in China Abrasives considerable influence. The internationalization of the domestic market may make abrasives manufacturing enterprises of China's domestic market share loss of part, of course, the domestication of the international market makes it easier to domestic enterprises to enter the international market, provided that domestic enterprises should develop their own initiative to use of the two markets and two resources the sense of accurate positioning in the international market, Chinese products, while maintaining low-cost open up new markets, develop new products.

(3), high-tech transformation, sustainable development

National economic growth is increasingly concentrated in improving scientific and technological level, competition in the market, mainly reflected in the level of product technology competition. At present several of the world famous abrasives manufacturing enterprises are to follow its own development philosophy walked a different path. The development of high starting point is more particular about product technology, marketing of high returns, and strive to jump out of the competition in the low product circle.

France, the United States, Austria, Japan and other countries continue to promote the abrasives improving the quality of the production industry as a whole, so its competitiveness in the international market is still a century ago. To South Korea, Taiwan as the representative of the rising star efforts to adjust industrial structure, optimize the mix as soon as possible to adapt to the challenges of the new situation.

In contrast, China's manufacturing enterprises in China Abrasives structural framework is still very scattered, the operating mechanism is still not live pan, manufacturing operations and research potential for lack of scientific and technological content. So, in this broad context, China's development of abrasives manufacturing enterprises to improve the quality of the first is a comprehensive, extensively absorb the technical achievements at home and abroad, give full play to the advantage of the post-tech and promote industrial upgrading.

(4), Economic Restructuring

At present, a series of supporting progressive reforms launched in abrasives manufacturing enterprises of China's enterprise reform, industrial restructuring and develop R & D capabilities to create an unprecedented enabling environment.

(5), domestic demand is a huge market

Abrasives has been the world's excess production capacity, national industries, the major companies on the market between the occupation of more intense. A huge domestic market demand is vigorous development of China's production of fertile ground for abrasives. National implementation of western development, central China, Hercynian economic zone and other strategies to enhance urban construction, the building of natural gas and west to east, north water diversion project, the plateau railway and a large number of key projects such as high-speed railway, Canada Great efforts on the transformation of traditional industries, the construction of such a large scale in developed countries experienced, and it is difficult to achieve in most developing countries, China's abrasives manufacturing enterprises should fully seize this historic opportunity, access to big development .

(6), stimulating domestic demand, and ten industrial policy

Revitalization plan in the equipment industry, high-grade abrasives their rejuvenation and development of content, which for the abrasives manufacturer fully utilize the technical resources, capital resources, market resources facilitated, so that manufacturers can abrasives a higher starting point to upgrade the industry's technical level, and enhance the competitiveness of products in the market at the same time will enable the government and enterprises have to speed up the pace and intensity of the reforms.

In addition, the implementation of China's new energy policy, and the crystalline silicon PV industry's rapid development, but also for our silicon carbide powder production and processing of development has brought unprecedented opportunities.

5, abrasive grinding the development prospects of the market

Abrasives Bonded Abrasives are ordinary domestic traditional products with a relatively stable domestic market. According to incomplete statistics, in 2007 the output of China's Bonded Abrasives and 31 million tons. Slower growth in domestic demand and exports growing rapidly. In 2007, exports of 140,000 tons ordinary abrasives, 1180 U.S. dollars / ton; imports of 8800 tons, 13,000 U.S. dollars / tons, import prices are export prices more than tenfold. As China's CNC machine tools, steel, automobile, shipbuilding and other industries and bearing a large number of the introduction of foreign production technology and technical equipment, using high-performance, precision, automation, special grinding processing technology, with a corresponding quality and level of abrasive put forward higher requirements. At present, China's high-quality abrasive products market in short supply.

Super-hard materials from the entire development of the industry point of view, China's super-hard materials, raw and auxiliary materials, has formed a production scale, but the product is still in development stage products relative to the raw and auxiliary materials, space for a larger appreciation.

Second, analysis of industry trends ABRASIVES

1, efficient high-precision automation is the product development steering wheel

Abrasives industry, a basic industries, but the machining is always occupy a very important position. The abrasives, there are three aspects of the improvement and breakthrough significance. First, the abrasive physical structure improvements, such as the role of the workpiece in unit time, an increase in the number of grit, so that grinding the average length of growth of the grinding contact surface increases, which has changed except the amount of grinding unit of time, effectively enhance the efficiency ; second, super-hard abrasive applications, mainly refers to the metal powder, metal oxide or CBN and other super-hard materials as filler to resin, ceramic or metal binding agent made of abrasive applications.

At present, brought about by the su, per-hard abrasive high-precision, high-efficiency grinding effect has been widely recognized; third, new abrasives appear, such as the composition of micron-level polycrystalline ceramic-ceramic abrasive, spherical shell containing fine diamond grit abrasive , ultra-precision polishing of polyester film tape and so on. These new abrasives are prominent features to be most vividly demonstrated adv, antages of grinding process.

Looking at the development of grinding area, the future will be abrasives grinding higher demands, to judge from the current situation, super-hard grinding products precisely meet these new needs. CBN abrasives, such as good thermal stability, high hardness, wear resistance and good properties, so the line of abrasive grinding, high-speed machining, grinding efficiency, grinding life expectancy high, especially suitable for processing high-speed steel, bearing steel , stainless steel, chilled cast iron and other ferrous metal materials. In addition, to meet the various needs of vitrified grinding wheel, large pore high-speed grinding wheel and the different sorts of processing abrasive grinding wheel, diamond saw blade and so on will be expanded as technology advances range of applications to become mainstream products grinding.

Abrasives industry, the products involved in three major categories: First, general abrasives, including the corundum family and silicon carbide, resin abrasives, ceramics, abrasives, etc.; Second, coated abrasives, including the emery cloth, sandpaper, abrasive belt and so on; Third, superhard materials, mainly diamond, cubic boron nitride and related products. Grinding is a machining can not be replaced but also the gradual expansion of the processing methods.

High efficiency, precision and automation of modern grinding technology, the pursuit of goals.

First of all, precision grinding and ultra-precision grinding: With the continuous emergence of high-tech products, spare parts machining accuracy and surface integrity of the higher and higher, the traditional to the ultra-precision grinding is grinding, ultra-precision grinding and polishing direction . Ultra-precision grinding is a systematic project, including high-speed high-precision grinding spindles, rails and micro-feed mechanism, precision abrasives and its balance and finishing technology, and environment purification and cooling of grinding methods.

Second, the high efficiency grinding: Grinding while machining accuracy and surface roughness has an unparalleled advantage, but the material removal rate is difficult to compete with other cutting. In order to improve grinding efficiency, with increasing the role of abrasive per unit time the number (such as high speed grinding, ultra-high speed grinding, belt grinding, etc.), increasing the average basal area of debris (such as a variety of re-grinding) and increasing the average length of wear debris (such as creep feed deep grinding, vertical flat grinding), and many high-efficiency grinding technology, including shortage of heavy-duty grinding, ultra-high speed grinding, abrasive belt grinding and High Efficiency Deep Grinding technology development is particularly eye-catching.

Third, with micron-level polycrystalline ceramic composed of microcrystalline abrasives used for abrasive belt grinding abrasive polishing of ceramic hollow spheres for superhard materials, diamond abrasive grinding of the spherical shell containing fine abrasive such as the use of a variety of new abrasive ; ultra-precision polishing of polyester film tape, containing abrasive powder Ni Yousi brush wheel, cast-iron bonded abrasive grinding wheels such as the emergence of many new; centimeter-level large-size synthetic diamond manufacturing; abrasive jet machining, abrasive water jet machining , visco-elastic Extrude Hone Abrasive Flow, the overall shape grinding, magnetic grinding, magnetic fluid precision grinding, low-stress grinding, ultra-high speed grinding and low speed grinding grinding large number of new processing technologies such as the emergence and development, etc. is also the world in recent years, the outstanding aspects of the development of grinding technology.

2, transition into the development of the industry to adjust the main theme of

Decline in the current global economy is in a period of economic cycles in different countries both W-type, there are seesaw down, as well as through state regulation of U-type, economic prosperity and decreasing the length of the cycle depends on the world economy, the environment and the authorities the Government's policy control. In 2009, China's macro-economic control a magnificent scale, results highlighted. From the current national policy mix boxing perspective, rather biased towards the protection of our society's construction, which undoubtedly will stimulate manufacturing and construction to pick up, and attached to these two industries can abrasives industry to tide over their difficulties, To this end enterprise may wish to devote more efforts to provide good service to these downstream firms.

Currently grinding industry's largest problem is insufficient demand, export frustrated; second block is the lack of innovation and market the product quality varies greatly, you must change the traditional mode of growth, using technological innovation to promote rapid and healthy development of the industry. Abrasive abrasive as metal products, "face" processing tools, has been affecting the entire hardware industry, the development of the nerve, in this global domino-style financial turmoil, the current domestic economy has been faced with upgrading and transformation, and the pattern of adjustment.

In this case, companies step up inner strength, structural adjustment and promote transformation to become abrasive grinding the main theme of the rapid development of the industry. Abrasives, executive vice president of branch-Sheng Chen suggested that we can come out by the state restructuring in the industry, from small factories, shareholding, the formation of large industrial groups, not only in price, quantity, both good control, enterprises are also more powerful the product deep processing.

Abrasives Branch Zhou Jinlong, deputy Secretary-General believes that the specifications are many kinds of abrasive, there is to do ceramic grinding wheel, abrasive cloth and paper, and cutting-edge solar energy materials, such as semiconductors, the company wants to make features of their products, doing fine, highlighting product quality, to achieve the difference in production, which avoided simply to maximize the quantity and price of the low degree of competition.

3, environmental protection and conservation into a low-carbon industry Keywords

By international economic and financial crisis conditions, all of the traditional industries are facing pressure from two sides of industrial upgrading, that is, emissions and energy consumption. National "Eleventh Five-Year Plan" emphasizes the adjustment of economic structure, changing the "high input, high consumption and high emissions, lack of coordination, difficult cycle, low efficiency" of economic growth mode characterized by efforts to build an economical and environment-friendly and innovative the production of power, the Government's energy, resources, and waste treatment increased the binding. Production is part of the abrasive type of energy resource consumption, and there is pollution, the state which must be controlled; the other hand, energy, raw materials, capacity, cost of capital, and so reduce the pressure to make corporate profits, will also affect the energy consumption of large, including grinding the industry.

As the UN Secretary-General Ban Ki-moon to personally boarded the North Pole's ice cap melting speed sent to the world faces a catastrophic deterioration of the global environment warning, a new round of international agreements for carbon emissions a big discussion with the "Kyoto Protocol" changes the responsibility to expand the scope and depth are being actively discussed in the international community. Low-carbon economy has become a hot spot and cause for concern.

Judging from recent policy, the country will not face the economic downturn of the economy to reduce the environmental governance and controls, which also highlights the government's determination to promote the industrial structure adjustment and upgrade. Abrasives industry in order to seek long-term development and national policy support, we must work hard to make energy-saving environmental protection articles, seeking the use of clean energy and clean production technology improvements.

4, marketing, quality and innovation into a business development driving force

Abrasive over 60% of enterprises rely on export-led, in 2009 1-4 months, artificial corundum total export 3 million tons, silicon carbide exported 27,000 tons, down 80% -90%, business operating rate was only 10%, abrasives industry 90% of the stove in a suspended state, greatly affected by financial crisis, some enterprises have even appeared layoffs. Relatively speaking, the abrasive enterprises affected by the financial crisis relatively small, the domestic application of more abrasive, the financial crisis, domestic demand is relatively stable during the period.

Can be seen that decline in profits was mainly abrasive market demand has waned. 3 Grinding of the 2009 1-4 year, gross domestic product fell by about 18% of products are widely used in automotive, electronics, home appliances, tools, in areas such as automotive and electronics applications accounted for 80%. Measures taken to respond to crises in three main aspects: First, to increase their marketing efforts, and second, to improve product quality level and the third is technical innovation, and strive to improve development potential.

5, the price holding stability and to follow the market rules

By the U.S. sub-prime crisis triggered by the global economic tsunami crisis that swept the entire world, Europe and the United States is still the world's major economies in an economic recession. China's economy has also been seriously affected, especially the import and export business, to July 2009, China's exports are still the month fell by 23%. China abrasives industry, in particular the abrasive industry, as exports relatively large proportion of possession, coupled by domestic metallurgical, nonferrous metals industry, the impact of the economic downturn, to the entire industry, surface to form an unprecedented economic crisis, to August 2009, abrasive industry, accounting for the operating rate of the actual production capacity of less than 20%, some difficulties in production and operations. Abrasives industry by stimulating domestic demand, and 4 trillion of China's investment-led, and the ten industrial revitalization plan of good drivers, business picked up rapidly early in the year is basically industry-wide recovery.

The crisis, some of China's abrasives business withstood a severe test, development has been maintained in a crisis. China is the world's abrasive producing and exporting countries, with manpower and resources, advantages, abrasive industry by leaps and bounds, the sharp rise in exports. At the same time, we should also see the entire abrasive industry overcapacity, oversupply and other issues. Competition for foreign customers, competition among domestic enterprises to lower prices, so that the foreign beneficiary of buyers.

Since the beginning of March 2007, due to rising raw materials and domestic electricity and improve abrasive prices are inevitable, relatively large-scale enterprises in the initial stage, and there is no price rise trend, trying to use take advantage of cost advantages. However, in raw materials and electricity prices continue to rise, especially when the Government stepped up environmental protection situation, some manufacturers were forced to stop production.

Large enterprises only some of the inventory that we can only supply customers. The face of foreign customers of the procurement information, insiders even said: "You are to how much money, but now they do not arrive to buy, because there is no cargo." Therefore, enterprises can only conform to laws of the market one after another price increase.

Domestic prices have also touched the abrasive international buyers interests in the international market, causing no small vibration. Although prices rose again, but the abrasive products in the international market, China still has a certain price advantage, so overseas buyers still consider the abrasive product imports from China. Business linkages with abrasive products found in China's current size and technological content of products needed to further improve. Fine-grained and high-tech products in the international market, demand is also high.
