Sandpaper is a member of coated abrasives, whose regular structure can ensure uniform grinding effect and reduce the difference of grinding. It is widely used for grinding and polishing mobile phones, cameras and laptops.
The technology trend of silicon carbide semiconductor instead of pure silicon semiconductor will push the rapid development of silicon carbide materials in the semiconductor and electronic industry in the future.
With the increasingly mature synthetic diamond technology as well as China's rapid economic take-off, we have achieved great progress on diamond tool manufacturing technology, and also have strong manufacturing capacity.
In view of this, Saint-gobain launched Norton Century45 high performance grinding wheel in earlier time, which greatly enhances the cost competition.
By the end of August, alumina manufacturers in China, completed a total of 72.15 million tons of production capacity and 60.43 million tons of operating capacity. The production operating ratio was about 83.76%, which fell 1.8% compared with last month.
Super abrasives industry in China has been developing gradually, and now formed a quite complete industrial system, including the raw material supply system, equipment supply system, auxiliary materials system and market system.
In Henan, the prevailing prices of white fused alumina Al2O3≥99% section sand are around 4000-4200 yuan/ton, and the factory prices including tax of fine powder are around 4300-4500 yuan/ton, which remain unchanged compared with last month.
With the development of superhard material tool technology, it can process almost all of the known materials, greatly improving machining efficiency and machining quality in the fields of various mechanical precision machining.
In view of the current domestic alumina market, it may remain stable in the near future. Therefore, enterprises must not purchase at a high price or at a low price for shoddy products when purchasing products.
Coated abrasives are designed according to specific applications, and the backing, abrasive grains, adhesive, coating and special production process all depend on different applications.
The viscosity of resin not only influences the performance of abrasive products manufacturing process, but also has a certain influence on the mechanical properties of abrasive products.
In recent years, coated abrasives have obtained rapid development, and are gradually replacing bonded abrasives in many fields, but it has not reached the product level of developed countries, with large development space in the future.
As long as there is one that does not comply with the above standards, they are low abrasive grains. Other indicators (such as particle size, etc.) can be done according to customer's requirements.
There are a lot of abrasives suppliers that are pay more attention to the packaging when they think the product quality is difficult to improve. Now, how abrasives suppliers will deal with green packaging in the face of "green packaging"?
For large or small coated abrasives companies, as long as they focus on innovation and continuous upgrade, they will obtain broader development space.
Although there are a lot of new products in the industry in recent years, the original products are not much. Most abrasives manufacturers have not enough fundamental and systematic research on coated abrasives.
With the continuous development of cutting technology, cubic boron nitride cutting tools have been widely used for processing high hardness and difficult-to-machine materials.
VSM abrasive belt is a new type of grinding material in recent years, which has stable grinding performance, high grinding efficiency, great grinding precision, long service life and other advantages.
Large aluminum giant's ability to control the industry becomes stronger and stronger, and the competition on the market share makes alumina industry collectivization increasingly highlighted.
Abrasives manufacturers need to consider how to deal with the cost reduction. In addition to the country's burden-reduction policy, economic support, abrasives manufacturers also need to reduce labor costs, transformation, innovation, etc.
