How to choose high-quality polishing powder to choose high-quality polishing powder, first we need to understand the composition of polishing powder, the composition of polishing powder is usually composed of iron oxide, zirconia, chrome oxide, cerium oxide, aluminum oxide, silicon oxide. And the difference in various components, the impact on the performance of polishing powder is also different, Ming Kang Industrial Xiaobian total the next few points.
1, the particle size of the powder:
The size and uniformity of the particles determine the polishing speed and accuracy. The mesh size of the sieve can grasp the relative particle size of the powder, and the average particle size determines the overall level of the particle size of the polishing powder.
2, powder Mohs hardness:
The relatively high hardness of the powder has a faster cutting effect, and the addition of some grinding aids and the like can also improve the cutting effect; different application fields will greatly differ, including its own processing technology.
3. Powder suspension:
Good polishing powder should have good suspension property. The shape and particle size of the powder have certain influence on the suspension performance. The suspension of the shape and fineness of the polishing powder is relatively better, but it is not correct. An increase in the suspension properties of the polishing powder can also be improved by adding a suspension.
4, the crystal form of the powder:
The crystal form of the powder is a single crystal particle agglomerated together, which determines the machinability, wear resistance and fluidity of the powder. The single crystal particles agglomerated together by the powder are separated (broken) during the polishing process, and the machinability and wear resistance are gradually decreased. The irregular hexagonal crystal particles have good machinability, wear resistance and fluidity. .
Summary, when the merchant chooses high-quality polishing powder, the first thing to look at is the supplier's polishing powder parameter index, whether it has the above four points, and secondly depends on the manufacturer's credibility, the manufacturer's family strength and so on.
