What is polishing material?
 
Polishing material is metal, stainless steel, metal using aluminum oxide, cerium oxide and other powder mixture on the workpiece (deburring, batch front, scale, etc.) for processing.
 
What is grinding powder?
 
Abrasive powder is used to improve and polishing of metal and other workpieces, grinding materials, surface roughness or powder.
 
What is a metal polishing material grinding powder?
 
Polishing materials Grinding powder is usually composed of ceria, alumina, silica, iron oxide, zirconia, chromium oxide and other components, different materials, different hardness, chemical properties in water are different, so the use of different occasions.
 
Domestic metal polishing material grinding powder technical requirements
 
Aluminum oxide and chromium oxide have a Mohs hardness of 9, ceria and zirconia of 7, and iron oxide lower. Cerium oxide and silicate glass high chemical activity, hardness is also quite, so widely used in glass polishing. In order to increase the polishing rate of cerium oxide, fluorine is usually added to the cerium oxide abrasive powder to increase the grinding rate. Molybdenum rare earth abrasive powder is usually mixed with 3-8 fluorine; pure cerium oxide abrasive powder is usually not doped with fluorine. For ZF or F series of glass, due to their smaller hardness, and the higher the fluorine content of the material itself, so the choice of non-fluorine abrasive powder is better.
 
First, a higher purity, excluding mechanical impurities;
 
Second, there is good dispersion, in order to ensure uniform and efficient processing, the right amount of dispersant can be added to improve the suspension rate;
 
Third, the particle size uniformity, within the allowable range;
 
Fourth, the metal polishing material grinding powder has the appropriate hardness and density, and water has good wettability and suspension, because the grinding powder needs to be mixed with water
 
Fifth, the powder particles have a certain lattice shape, forming sharp edges and corners when broken to improve the polishing efficiency.
