Basic Requirements For Polishing Powder
Apr 17, 2018

(1) The particle size of the fine powder is uniform and within the permissible range; the size and uniformity of the particles determine the polishing speed and precision, and the number of meshes of the sieve can grasp the value of the relative particle size of the powder. The average particle size determines the polishing. The overall level of powder particle size.

(2) High purity and no mechanical impurities.

(3) Good dispersion and adsorption, to ensure the uniformity and high efficiency of the process, appropriate amount of LBD-1 dispersant can be added to increase the suspension rate; good polishing powder should have good suspension, the shape of the powder Particle size has a certain influence on the suspension performance. The nano-particle size polishing powder has relatively better suspension performance. Therefore, the nano polishing powder is generally selected for polishing.

(4) The powder particles have a certain lattice morphology, and sharp sharp corners are formed during crushing to improve the polishing efficiency. The crystal form of the powder is a single crystal particle that agglomerates together, which determines the machinability and wear resistance of the powder. And mobility. The single-crystal particles in which the powders are agglomerated are separated (broken) during the polishing process, so that their machinability and wear resistance are gradually reduced, and the particles with a spherical shape have good machinability, wear resistance, and fluidity.

(5) have suitable hardness and density, and water has good wettability and suspensibility, because the polishing powder needs to be mixed with water, powder with relatively high hardness has a faster cutting effect, and some grinding aids are added at the same time, etc. The same can also improve the cutting effect; different applications will have a big difference, including their own processing technology.
