Guangdong Silica abrasive polishing materials prices where good

First, the polishing material Silica Overview: With the development of modern technology, surface treatment of the material also requires higher and more refined, so we superfine grading out spherical silica powder preparation is not easy on the surface to generate random draw injury, and can provide the best grinding efficiency and surface finish, applied polished metal surface, Precision Valve, hard disk, CD-ROM, the head of polishing, wash bearings, automotive polishes, have a good effect. Experimental results show that such abrasive powder can reduce the number of grinding and polishing at least 10-20%, to achieve rapid grinding and polishing. ? At the same time, high-purity spherical silica powder are also widely used in optics and precision grinding optoelectronic industry, especially for grinding, polishing semiconductor crystal polycrystalline silicon wafer, funnels glass screen, optical glass, liquid crystal displays (LCD, LED) glass substrate piezoelectric quartz crystal, compound semiconductor material (gallium arsenide, indium phosphide), magnetic materials and other semiconductor industries. Silica particles because of their close circle, through ultrafine, superfine grade prepared then by modification, is a good abrasive cleaning metal parts, such as bearings in the wash, finish up to 3.0 or more, than the display similar products. Also used in the semiconductor industry, precision valves, hard disk, magnetic head polishing, car polishing agents, have very good results. Second, our product specification sheet: Silica polishing material specification 400 mesh 600 mesh 800 mesh mesh 1250 1000 1500 4000 2000 mesh mesh mesh mesh 8000 6000 10,000 head three head, polishing material superiority of silica powder: a polishing liquid Good degreasing, rust, cleaning and credit performance, and make metal more than the original luster. The product is stable, non-toxic, environmental pollution and other effects, light liquid to use: includes ratchet wrench, open end wrench, screwdriver, Tsui, wrenches, hex wrench, screwdriver, pewter, zinc alloy and other metal products through After grinding, a polishing agent with the vibration grinding polisher, drum-type grinding machine for polishing optical type; a polishing agent put the amount (depending on the size of different products, polisher size and brightness of each company's product requirements properly configured), 2: polishing time: the product according to the state to decide. 3, after washing with water once polished finish and drying can be. Fourth, the development prospects of polishing materials microsilica: Polished not improve the dimensional accuracy or accuracy of the workpiece geometry, but to give a smooth surface or specular gloss of purpose, and sometimes to eliminate gloss (extinction). Polishing, buff (peripheral speed 20 m / sec or more) high-speed rotation of the workpiece pressed, the abrasive on the workpiece surface micro machining and rolling, to obtain a shiny finished surface, the surface roughness Ra0.63 generally up to 0.01 micron; when using a non-greasy matte polish, shiny surfaces can matting to improve the appearance. Will throw a lot of balls coarse, abrasive lime and cans on the tilting drum, the drum is rotated so randomly and so the ball rolling with the abrasive collision in the barrel in order to achieve the removal of a convex front surface and reduce surface roughness purpose, can remove margin of about 0.01 mm. Buff adopt uniform fine material degreased felt fine wood or specially made, its trajectory is uniformly dense mesh, polished surface roughness of not more than Ra0.01 microns were observed under magnification 40x microscope not any surface defects.
