What is polishing material?
Polishing material is metal, stainless steel, metal using aluminum oxide, cerium oxide powder mixture on the workpiece (to burr, batch front, oxide, etc.) for processing.
What is grinding 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 materials, abrasive powder, usually by cerium oxide, alumina, silicon oxide, iron oxide, zirconium oxide, chromium oxide component composition, the different materials of different hardness, in the water chemical properties are also different. Therefore, the use of different circumstances.
Technical requirements of grinding powder for 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 chemical activity is higher, hardness is also considerable, so widely used in glass polishing. In order to increase the polishing speed of cerium oxide, the grinding powder is usually added to the cerium oxide powder to increase the grinding efficiency. Mixed rare earth grinding powder with low cerium content is usually mixed with 3-8 fluoride; pure cerium oxide powder is usually not doped with fluorine. For ZF or F series of glass, because of its own hardness is smaller, and the material itself has a high fluorine content, therefore, because of the choice of fluorine free grinding powder is good.
First, there is a high purity, no mechanical impurities;
Second, there is a good dispersion, to ensure that the processing process of uniform and efficient, can be appropriate to add a dispersant to improve the suspension rate;
Third, particle size uniform, within the allowable range;
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 be mixed with water
Fifth, the powder particles have a certain form of crystal lattice, broken when the formation of sharp edges and corners, in order to improve the polishing efficiency.
