Huicong Network: what is the surface treatment of polishing material?
Polishing material is metal, stainless steel, metal using aluminum oxide, cerium oxide and other powder mixture on the workpiece (to burr, batch front, oxidation skin, etc.) for processing.
What is the abrasive powder?
Grinding powder is used to improve the metal and other parts of the polishing, polishing materials, surface allowance or roughness of the powder.
What is metal polishing material grinding powder?
Polishing material grinding powder is usually composed of cerium oxide, alumina, oxidized silicon, iron oxide, zirconia, chromium oxide and other components, the hardness of different materials, the chemical properties of the water is also different, so the use of different occasions.
Technical requirements for the grinding powder of metal polishing materials in China
Alumina and chromium oxide Mohs hardness of 9, cerium oxide and zirconium oxide is 7, lower iron oxide. Cerium oxide and silicate glass with high chemical activity, the hardness is also quite, so widely used in glass polishing. In order to increase the polishing speed of cerium oxide, the addition of fluoride in the cerium oxide grinding powder is usually added to the grinding rate. The mixed rare earth grinding powder with low cerium content is usually mixed with 3-8. For ZF or F series of glass, because of its low hardness, and the content of fluorine in the material itself is higher, so it is good to use non fluoride.
First, there is a higher purity, not containing mechanical impurities;
Second, a good dispersion, in order to ensure the process of uniform and efficient, can be appropriate to add dispersant to improve the suspension rate;
Third. The size of the powder is uniform, and the size of the powder is allowed;
Fourth, metal polishing material grinding powder has the appropriate hardness and density, and water has a good wettability and suspension, because the grinding powder need to mix with water
Fifth, powder particles have a certain lattice form, breaking the formation of sharp edges and corners, in order to improve the polishing efficiency.
