Nanometer silicon dioxide

In addition, nano-silica can also be widely used in ceramic (enamel) porcelain, gypsum, batteries, paints, adhesives, cosmetics, glass, steel, chemical fiber, acrylic, and environmental protection and many other areas of the product mention upgraded

Magnetic Materials: coke in iron powder added to silica-based composite powders was modified by testing the product to reach the main performance of existing similar products in the United States the highest level, such as the remanence flux density greater than 4100 Gs, in Intrinsic coercive force is greater than 3000 Oe, magnetic energy product is greater than 4 mGOe, while the production cost of materials decreased significantly.

Color Rubber: In the solution-polymerized styrene-butadiene rubber, etc. to add a small amount of nano-oxide silicon (alternative black) as a reinforcing agent and anti-aging agent, to produce colored rubber products, toughness, strength, elongation, flexural and anti-sex aging performance are met or exceeded the EPDM rubber.

Plastics: Nano-oxide silicon fully dispersed in polypropylene (PP), polyvinyl chloride (PVC) and other plastic raw materials, plastic products can significantly improve the strength, toughness, wear resistance and anti-aging properties. Such as nano-modified PP, its water absorption, insulation resistance, compression residual deformation, flexural strength and other key performance indicators were met or exceeded the engineering plastic nylon 6, the products to improve weather resistance more than doubled in some areas, an alternative to nylon 6.

Coating: In the water-based latex paint on the basis of the original recipe, adding the total weight of copies of 0.3-1% of the nano-oxide silicon (the need for full decentralization), its suspension stability, thixotropy, between the coating and the substrate combination of strength, finish, etc. performance, have received significantly increased, drying time, accelerated aging test of time multiplied by UV resistant scrubbing of thousands of times by up to tens of thousands of times, while stains coating also improved significantly.

Main uses:

Nano-silica particle size is small, narrow size distribution, micropore more than the large surface area and high content of surface hydroxyl groups, ultraviolet, visible and infra-red reflective ability and so on. ; Test analysis by the BET method, nano-silica large specific surface area; by IR spectroscopy, nano-silica surface of a large number of hydroxyl and unsaturated residue key, and deviate from the steady-state silicon-oxygen structure; use of Cary-5E Mapping Spectrometer testing, nano-silica on the ultraviolet light, the long-wave, as well as visible light has a high reflectivity; Omnisorp100CX surface area and porosity with the analyzer measured P-type nano-silica surface contains a number of nano-porous, its porosity rate 0.611ml / g.
