Supply of silica powder microsilica ultrafine microsilica

1, fine quartz sand, quartz powder is made of high quality have been selected, the thickness of the crushing, acid treatment, washing, drying, sieving plastic, magnetic separation and a series of processing, the main ingredient: SiO299.5-99.9%, Fe2O30 .01-0.05% appearance of white crystals, the annual output of 20,000 tons. Size range: 2-200 mesh, (10-0.0075mm) according to user requirements particle production. Main purpose: the production melting quartz, precision casting, abrasive wheel, advanced glass products, refractories, etc., are exported to Japan, Korea, Singapore and other countries. 2, electric melting quartz block, sand, pink with fine quartz sand melting temperature, rapidly cooling after crushing blocks made of artificial classification, main components: SiO2≥99.5-99.9%, Fe2O3≤0.002%. First grade is colorless and transparent, with a small number of transparent mist, and users can request processing a variety of sand grain size, powder, the annual output of 8,000 tons size range: 10-1mm, 1-0.5mm, 0.5- 0.2mm, 0.2-0.1mm, now using advanced processing technology and processing equipment, after colliding material crusher, magnetic separator, plastic machines, jet mill, vibration mill, classifier and other processes processed into various size electricity Fused Silica sand powder. The product mix without intermediaries magazine, basically unchanged ensure that the original ingredients during processing. Size according to user requirements main purposes: for advanced refractory materials and electrical and electronics industries, are exported to Japan, South Korea, the United States and Europe and other countries www.hnweifen.com Contact: Miss Tian Tel: 18703604889 QQ: 296355064
