Rare Earth 2.2μm Optical Polishing Powder For Crystal Crafts
The particle size and distribution of rare earth polishing powder have an important influence on the properties of polishing powder.For the polishing powder with certain composition and processing technology, the larger the average particle size is, the greater the grinding speed and surface roughness of glass will be. In most cases, the grinding speed of polishing powder with particle size of 4 μ m is the highest. The standard polishing powder generally has a narrow particle size distribution, with few too fine and too coarse particles. The polishing powder without large particles can polish a high-quality surface, while the polishing powder with few fine particles can improve the grinding speed.
