Optical devices and optoelectronic industries with precision abrasive powder, metal surface treatment, grinding medium (polishing) with silica fume 

 Xinlei Powder Technology, Precision Grinding ball high purity silica powder ~ devices for optical and optoelectronic industry, precision grinding, especially for grinding and polishing of semiconductor single crystal silicon films, Picture Tubes glass screen, optical glass, liquid crystal display (LCD, LED) glass substrate, piezoelectric quartz crystal, compound semiconductor materials (gallium arsenide, indium phosphide), magnetic materials and other semiconductor industry. 

 Through ultra-fine silica powder company Xinlei, grade superfine powder prepared is a good polishing metal parts cleaning abrasive, such as washing the application of bearings, finish up to 3.0 or more, than similar products. Also for polished metal surface, precision valves, hard disk, magnetic head polishing, car polishing agent, had good results, because of its spherical particles, and so different from the traditional abrasive product type, this shape so that the movement in the grinding abrasive particles being processed surface, resulting in the grinding effect of sliding, rather than the traditional abrasive grinding, which is not easy to generate random scratches on the surface. Meanwhile, the grinding pressure is evenly distributed in the abrasive surface to reduce particle breakage, wear a substantial increase, which can provide the best grinding efficiency and surface finish. Experimental results show that abrasive grinding and polishing powder can reduce the number of at least 10-20%, to achieve rapid grinding and polishing, advises clients to use the traditional 60% of the amount of abrasive as a starting point. 

 Xinlei powder company with independent intellectual property patents technology, products and stable supply to Japan, the United States, Europe, Korea and domestic customers, domestic users has been gradually replace imported products with my company. Grinding and polishing materials I lead at home.
