How to choose glass polishing powder. The following are 5 factors.
1. How to choose glass polishing powder-The particle size of the powder
It determines the polishing precision and speed, how many meshes and the average particle size of the powder are commonly used. The mesh size of the sieve can grasp the value of 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. How to choose glass polishing powder-Mohs hardness of powder
powder with relatively high hardness has a faster cutting effect, and the addition of some grinding aids, etc. can also improve the cutting effect; different application fields will vary greatly, including its own processing technology .
3. How to choose glass polishing powder-Suspension of powder
Good powder requires that the glass polishing powder has better suspendability. The shape and particle size of the powder have a certain influence on the suspension performance. It ’s better, but not definitive. The improvement of polishing powder suspension performance can also be improved by adding suspension (agent).
4. How to choose glass polishing powder-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 that are agglomerated with powder are separated (broken) during the polishing process, so that their machinability and wear resistance are gradually reduced. .
5. How to choose glass polishing powder-Appearance color
The content of Pr in the raw material is related to the burning temperature and other factors. The higher the content of praseodymium, the powder is brownish red. The low-cerium polishing powder contains a large amount of praseodymium (cerium praseodymium material), which makes it appear reddish brown. High cerium polishing powder, the higher the burning temperature, it appears white pink, the temperature is low (about 900 degrees), it appears light yellow.
