The beneficial effects of the present invention are:
1) this polishing fluid is abrasive material by the alpha-type aluminum oxide micro mist that purity is 99.99% purity, the alpha-type aluminum oxide micro mist in polishing fluid
Mass percentage be 1 ~ 30%, if the content of alpha-type aluminum oxide micro mist is too low, the rate of polishing will be reduced, if α type
The content of alumina powder is too high, and polishing fluid system is not easy to disperse, and the mirror effect of polishing is bad, and wastes raw material.
2) particle diameter distribution of alpha-type aluminum oxide micro mist used in the present invention is between 0.5 ~ 2.0 μm, throwing within this range
Aluminium alloy after anodic oxidation and dyeing can be polished out good mirror effect by light liquid.Abrasive size is too small, polishing speed meeting
It reduces, partial size is too big then for leaving scratch on burnishing surface, influences product surface appearance.
3) abrasive material can be uniformly dispersed in by polishing fluid of the present invention in used dispersing agent in the case where low viscosity
In system, and be adhered on buff well again, polishing fluid is not easy to splash when high-speed rotation, it is ensured that the efficiency of polishing and
The usage amount of polishing fluid.
4) polishing fluid of the invention can be very good the rate of control polishing, can uniformly remove the table of anode oxide film
Layer, reaches the mirror effect of almost Perfect, while not will cause the locally heterochromatic feelings of the anodic oxidation film surface through dyeing processing
Condition.
