Development status of superhard material coated abrasives

With the development of the national economy, the demand for coated abrasives and the application fields in China are still expanding. The production of coated abrasives is still in a period of rapid development after the rapid development stage, and the coated abrasives enterprises still have Great room for growth.

 

 

 

1. The demand for coated abrasives is huge.

 

First of all, China's steel and automobile production ranks first in the world, and the metal and wood processing industries are developing rapidly. The demand for high-quality, multi-variety coated abrasives, especially abrasive belts, is increasing. According to Chen Yuandong, deputy secretary-general of the Tu-Xie Association, in 2010, China's machine tool industry achieved an output value of 553.68 billion yuan, a year-on-year increase of 40.6%; national automobile production and sales reached 18.246 million and 180.619 million units, an increase of 32.4% and 32.37% year-on-year; It has reached 140 million square meters; the furniture industry has completed a total output of 770 million pieces, an increase of 27.8% over the same period of the previous year. Among them, the cumulative output of wooden furniture has reached 62.76 million, an increase of 26.4% over the same period of last year, and the cumulative output of metal furniture has reached 42.813 million pieces, a cumulative year-on-year increase. 31.3%, the total output of software furniture was 47.711 million pieces, an increase of 16.8% over the same period of last year; the national shipbuilding completion volume was 65.6 million DWT, an increase of 54.6%; the world sales of white goods and small household appliances such as refrigerators and washing machines increased in 2010. 6.9% (3,154.48 million units), while China accounts for 85.3% of the world's total home appliance market, far exceeding other regions. Therefore, the Chinese economy is still developing at a high speed. The coated abrasives that occupy an important position in the industrial manufacturing and processing industries have always been known as “industrial beauticians”. The polishing and grinding processes in these areas are the places where they can show their talents. Secondly, the high-grade coated abrasives have a huge gap, and the import of products is growing at a high speed. In particular, the imports of coated abrasives based on other high-grade materials have increased significantly, and domestic purchasing power is strong. In 2010, the quantity and amount of imported abrasives in China reached 18,215 tons and 190 million US dollars respectively, with an increase of 54% and 58% respectively, and the trade deficit reached US$ 22.77 million. Third, in fact, in some developed countries such as the United States and Germany, the sales of coated abrasives have been the first in the series of coated, consolidated and superhard abrasives, and the output value is the total output value of abrasives. More than 40%, of which Germany has reached 50%, and the proportion of China's coated abrasives in the entire abrasive tool is far below this level, and the growth potential is great.

 

 

 

2. China's coated abrasive products are booming in production and sales.

 

The advantages of coated abrasives in China are becoming more and more obvious, and the overall situation is in the situation of both production and sales. According to the industry association's report on the 60 key enterprises in the industry, in 2010, the production of coated abrasive products reached 406 million square meters, an increase of 5.2% year-on-year; the total industrial output value of the year was 4.97 billion yuan, an increase of 31.7%; The sales value of sales was 4.32 billion yuan, up 18.8% year-on-year; the sales rate of industrial products reached 97%, up 13% year-on-year; especially in the third quarter, the growth rate of industrial output value reached 120.9%, and the growth rate of product sales revenue reached 88.6%. In addition, the total number of coated abrasive products is almost equal to that of resin sheets and grinding discs, and even individual products are even worse. The varieties and specifications of coated abrasive products are no less than the recent rapid development. Hard products. In 2010, the export quantity and amount of coated abrasives in China reached 50,160 tons and 170 million US dollars respectively, both hitting record highs, with an increase of 24.9% and 41.8% respectively. The increase was more than the quantity increase, and the average unit price rose by 13.5%, indicating that the export products Has been very competitive, and the product quality has also improved significantly. Everyone's self-confidence has never been more than ever. They can no longer stay in the past blindly. They can basically evaluate their products objectively and correctly. "Knowing oneself and knowing each other, and fighting for nothing" is not the same. However, there are still many companies with weak technical strength and a lot of room for improvement. In the communication with everyone, individual companies "know their knowledge but do not know why", in the use of raw materials, "good steel is used on the back of the knife."

 

 

 

3. The production of coated abrasives in China has basically formed intensive and large-scale, and the industrial ecological chain can be positively interacted.

 

Compared with the increasingly dispersed production of bonded abrasives and superhard products, the most notable feature of coated abrasives is that their upstream products are gradually intensifying and scaled, and the overall development is benign. Enterprises rely mainly on product and quality competition, and have already stepped out of the vicious circle of price wars in the past and entered a benign development track. In 2010, there were 13 coated abrasives production enterprises with a national output of more than 10 million square meters, accounting for 82.8% of the total output; 13 enterprises with an annual output value of more than 100 million yuan, accounting for 78.5% of the total output value. Although there are still a large number of coated abrasive products enterprises, like fixed abrasives and super-hard products companies, the scale is relatively small, the concentration is low, and many are still family-owned management and workshop-style production, lacking innovation ability, is the industry. The bottleneck of development, but under the guidance of upstream enterprises, in order to speak and compete, in recent years, restructuring and integration have also begun. In 2010, after more than half a year of planning, the three coated abrasive conversion enterprises - Shanghai Gaofang Abrasives Co., Ltd., Wenzhou Ziniu Grinding Co., Ltd. and Shanghai Xinwuji Abrasives Co., Ltd. Wuzifang Abrasives Co., Ltd. is a typical case. Abrasive production plants have begun to develop new products for coated abrasives at the crystal level. A series of new corundums such as Taibake corundum, Dongfeng corundum and Xixia corundum have contributed a lot to improving the quality of coated abrasives. Calcined corundum and semi-finished The amount of brittle corundum and zirconium corundum is steadily increasing; the gap between the original fabric and high-grade paper produced by the substrate manufacturer is shrinking; the superhard material polyester coated abrasive such as diamond and cubic boron nitride represented by Zhengzhou Reiter Has successfully entered the market; the production and supply of binders has been basically synchronized with the international level; polishing machines, butt film, punching machine, laminating machine, grinding machinery have formed an industrial ecological chain, promote each other, improve together, and have great vitality.

 

 

 

4. China's coated abrasives market is globally integrated, and many top international companies compete in China.

 

Through “bringing in and going out”, domestic coated abrasives have been integrated into the international market, and major changes have taken place in industry scale, product quality, process technology and management experience. The overall strength is being improved by a coated abrasives. Move toward a strong country with coated abrasives. High-tech, new and fine-coated abrasive products from well-known international brands have all appeared in the competition, and China is becoming the world center and international stage. The Italian IM&T company, the German Schwabe company and the BIKO company that produces conversion equipment for the production of new coated abrasive manufacturing equipment have provided a number of coated abrasive production lines for China in the past 30 years. The famous French Alvorwigs Paper Company, Napoleon Sandpaper Company, and the Finnish-based Taier Group have established joint ventures or wholly-owned factories in various parts of China. The Group is also planning to build in the next few years. Up to 5 production and R&D bases to serve China's huge market in a timely and efficient manner. The phenolic resin produced by Kunming Resin Materials Technology Co., Ltd., a joint venture between Kunming and Taiwan's CASHEW, has a market share of more than 60% in the abrasives market in South China. In addition, the ceramic abrasive belts, the accumulated abrasive belts, the zirconium corundum belts of the German VSM company and the Japanese bison company, and the nylon series of the US 3M and the sharp UNION have all been unique in their respective fields.
