With the continuous development of society, the demand for surface treatment of products is higher and higher. For SiO2 material polishing powder with good light effects, but the cutting rate is too slow; and for diamond or SiC materials with hardness 10 and fast cutting, but there are scratches on the surface. According to the market demand, our company independently developed series of aluminum oxide polishing powder products with moderate hardness, and they’re more suitable for fine polishing. By selecting the right particle size 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 particle size product, the cutting rate will be increased obviously by improving the solid content in the polishing liquid.
At present, our company has two series of products, GD and GDS. GD series are mainly used for the final polishing of mirrors of sapphire and others. GDS series are specially applied to automotive paint polishing, resin lens polishing, high-grade furniture paint polishing field.

GD series product features
●Water-solution easily dispersible, particle dispersion, good suspension, can be directly made into polishing slurry by clients. Solid content 1%~60% with arbitrary adjustable, stable liquid phase.
●Crystal phase is stable and hardness can be adjusted (BET 1-30m2/g),
small particles and the uniform particle size distribution;
●Fast appearing Light, strong cutting force, bright luminosity, excellent mirror effect;
●High grinding efficiency, efficiency is much higher than silicon dioxide (SiO2) and other mild abrasives, the surface finish is superior to the polishing effect of white fused alumina, can polish uniform and bright luster.
Market application of GD series products：
●Phone screen polishing, including the final polishing of Sapphire mobile phone screen and glass mobile phone screen.
Can also be applied to: artificial stones, zircon,high-grade glass, natural stone, jade, agat
and other vibration polishing (machine polishing, rolling polishing), manual polishing, etc,
●Metal polishing, including final polishing of mobile phone shells, automotive wheels, high-grade hardware.
Can also be applied to the grinding polishing of aluminum, copper, stainless steel, stone, ceramic tile.
