We are a professional brown fused alumina, white fused alumina, black corundum, pink corundum, green silicon carbide, black silicon carbide and other abrasive products manufacturer and supplier in China.

If there are too many silica, the excessive silica can not be retained in the glass phase, but react with part of alumina to form mullite, which will reduce the toughness of brown fused alumina. The higher the aluminum content, the better the toughness; this is also a very important reason that the raw material of Brown Alumina must be bauxite. Calcination process. Brown corundum is first calcined in a rotary furnace, and then it flows into a vertical furnace for supplementary calcination, so as to effectively prevent the color of abrasive from blooming.

General use of detergent are some neutral detergent, which is conducive to clean white corundum and will not harm white corundum. If a non neutral detergent is used, it can play a role in cleaning but damage white corundum, which is wrong, and should be prevented as much as possible during cleaning; the covering is elegant, and the covering generally uses specific substances, which can not cover the carpet for a long time, and sundries will affect white corundum, because white corundum has many chemical properties.

Brown corundum has bauxite in its material, which brings another function to brown corundum, that is, it can be used as aggregate, which is the fifth function of brown corundum. The electric fused brown corundum grain size sand is made of manually selected brown aluminum oxide blocks and processed by roller, ball mill, bamak and other equipment. The grain size is f8-f325. It is mainly used for polishing, grinding, industrial grinding, etc. it can also be processed by water washing, acid pickling and other methods according to the requirements of customers, which can meet the different needs of customers.

White corundum is the most easy to appear and difficult to avoid is water stain. In general, water stain can play out in a certain period of time, but in the condition of high sea temperature, water stain may not be offset. It is stored all the year round, and each dye object (except fluid) will not affect the stone itself. Only after the object catches up with water, chemical changes occur, batik and then become, so it can be concluded that (water) is the biggest enemy of stone It can only be solved by blocking the pores of the stone.

It can make the surface of the workpiece get a certain degree of cleanliness and different roughness, change the surface tensile stress to compressive stress; improve the lubrication state of the surface; reduce the motion noise of the coupling parts; improve the friction coefficient of the surface. Polishing of workpiece surface, brown aluminium oxide polishing of metal external decoration surface, hardware tool or diffuse reflection surface, and polishing of woodwork surface. The comparison between the pouring method and the fritting method is as follows: the temperature of the furnace liquid is more than 2050 ℃.

In winter, the road surface is prone to waterlogging and slipping in rainy and snowy days, which corrodes the bridge steel plate, and the anti-skid performance is poor in freezing weather. These are used in industrial areas. Brown fused alumina may also be used in other individual industries. At present, the domestic manufacturers mainly use blowing oxygen method, secondary calcination method and adding oxidant method to control the carbon residue of brown corundum, and achieved some results Brown corundum has many characteristics in the application process.
