Specialty Alumina For Fine Polishing

2019-05-03 admin

With the polishing industry development and increasing demand for the surface treatment, SiO2 material polishing powder with good light effects, but cutting rates too slow; diamond polishing powder or SiC materials with hardness 10 and fast cutting, but scratches on the surface. According to the market demand and after 3 years of independent research and development, our company can produce series of aluminum oxide polishing powder products with moderate hardness, and it’s more suitable for fine polishing. By choosing the right grain products and adjusting the solid content in the polishing liquid (1-60% adjustable), it will be achieved high cutting rates and fast light effect. For the same size product, by improving the solid content in the polishing liquid, and then cutting rates will be increased.
At present, our products are mainly for the fine polishing powder with capacity over 20 tons per month, and can be applied to the final polishing of Sapphire.
