1, polishing powder materials

Polishing powder usually consists of cerium oxide, alumina, silicon oxide, iron oxide, zirconium oxide, chromium oxide and other 

components, different materials of different hardness, in the water chemical properties are also different, therefore the use of oc

-casions each not same. Alumina and chromium oxide Mohs hardness 9, cerium oxide and zirconium oxide is 7lower, iron oxide.

 Cerium oxide and silicate glass with high chemical active, hardness is also quite, it is widely used in glass polishing.

2, the basic requirement of polishing powder

(1) particle size uniformity, within the range of permission;

(2) have a higher purity, without mechanical impurity;

(3) has good dispersion and adsorption process, to ensure uniform and efficient, may be appropriate to add LBD-1dispersant to 

improve the rate of suspension;

(4) the powder particles have a certain lattice morphology, broken form sharp angle, in order to improve the polishing efficiency;

(5) a suitable hardness and density, and the water has good wettability and suspension, because the polishing powder need to be 

mixed with water

3, cerium oxide particles

Big particle size of cerium oxide, grinding force increases, more suitable for harder materials, ZF glass should be used fine polishing 

powder. Note that, all of the cerium oxide particles have an average particle size distribution, or median diameter of D50 size deter

-mining only the polishing speed, while the maximum size Dmax determines the polishing precision. Therefore, in order to obtain 

high accuracy requirement, must control the maximum particle polishing powder.

The processing technology for: by roasting after ultrafine grinding or superfine classification
