Details:

Features: Selection of high-quality powder quartz and quartzite, chemically bleached, ultra-fine processing to obtain fine silica powder. Product high whiteness, gloss and good resistance to corrosion, acid, chemically inert and neutral pH, hardness, high filler content properties with particle surface porous - the pore volumes:0.9 cm3/g and size diameter <500nm, can increase the rigidity and wear resistance. Widely used in polysilicon, paint, coatings, glass, construction, plastics, rubber, glass, casting coatings, ceramic glaze, abrasive materials, adhesives, sealants, silicone, epoxy resin and so on. The main purpose: Coatings, paints, ceramic glazes, abrasive materials, Silicone rubber, plastics, casting and other. Ultra-fine silica powder used in high-grade paint (primer, road paint, marine paint, etc.) can play a role in filling capacity. increase thickening, but also improve the fineness of the paint, leveling, film hardness. Ultrafine silica powder for the new plastic: in particular, translucent plastic film, after adding ultrafine silica powder, greatly improving the transparency of strength, toughness, water resistance, storage insulation properties. After addition of silica powder in plastic parts, and its mechanical performance can be increased by 1 to 3 times. Ultrafine silica powder for modified resin-based composites can improve its overall performance, increase strength, toughness, elongation, abrasion resistance, smoothness, anti-aging. Ultrafine microsilica for new rubber, silicone rubber material: silicone rubber can improve the strength of the product (filling amount 30-65%); anti-ultraviolet radiation, infrared-reflective, high dielectric insulating indispensable fine filler; in other After the rubber ultrafine silica powder is added, its flexibility, strength and toughness, wear resistance and so increase significantly...

The product making method: Strongly Forced air flow crushing method
