Affecting The Performance Of Polishing Powder
Apr 17, 2018

(1) The particle size of the powder: It determines the precision and speed of polishing, the number of meshes used and the average size of the powder. The mesh size of the sieve can be used to determine the relative particle size of the powder. The average particle size determines the overall level of the particle size of the powder.

(2) Mohs hardness of powder: Powder with relatively high hardness has a faster cutting effect. Adding some grinding aids at the same time, etc. can also improve the cutting effect; different application fields will have great differences, including their own processing Process.

(3) Powder Suspension: Good powder requires that the polishing powder should have good suspension, and the shape and size of the powder have a certain influence on the suspension performance, and the suspension of the polishing powder having a relatively fine shape and particle size is relatively effective. It's better, but it's not correct. The improvement of the suspension performance of the polishing powder can also be improved by adding a suspension (agent).

(4) The crystal form of the powder: The crystal form of the powder is a single crystal particle that agglomerates together, which determines the machinability, wear resistance, and fluidity of the powder. The single-crystal particles in which the powders are agglomerated are separated (broken) during the polishing process, and their machinability and wear resistance are gradually reduced. The irregular hexagonal crystal particles have good machinability, wear resistance, and fluidity. .

(5) Appearance color: The content of Pr in the raw material is related to the burning temperature and other factors. The higher the lanthanum content is, the powder is brownish red. The low-abrasive polishing powder contains a large amount of bismuth, which makes it look brownish red. Sorghum polishing powder, the higher the burning temperature, it is white pink, low temperature (about 900 degrees), which was pale yellow.
