Nano silica feature phase nano silicon dioxide with small particle size, pore, large specific surface area, high surface hydroxyl content more, ultraviolet, visible light and infrared reflection ability, etc. Especially with the improvement of the product surface treatment technology, soft reunion of nanoparticles was significantly reduced, and the compatibility of organic polymer materials, greatly broaden the application field of the product.

Properties: White, solid colloidal particles, primary particles from 5 to 40 nm (nm), has significant thixotropic, reinforcing, thickening, filling, etc, except hydrofluoric acid, strong alkali, in all of the solvents and cannot dissolve in the liquid.
Product application: 1, the coating material: In water-based latex paint, on the basis of the original formula, add the total weight of 0.3 1% of nano silica (need to be fully dispersed), after its suspension stability, thixotropy, bonding strength between coating and substrate, bright and clean degree obtained significantly higher performance, such as drying time shortened, artificial accelerated ultraviolet aging test time multiplied, scrubbing resistance from thousands of times to tens of thousands of times, at the same time, the fouling resistance of coating is improved significantly. 2, plastic materials: Nano silicon dioxide fully dispersed in polypropylene (PP), polyvinyl chloride (PVC) plastic raw materials, can significantly improve the strength of the plastic, toughness, wear resistance and aging resistance. Nano modified PP, such as the water absorption, insulation resistance, compression residual deformation, flexural strength and so on key performance indicators are reaching or higher than engineering plastics nylon 6, more than double product weatherability, in some areas can replace the nylon 6. : 3, adhesives The nanometer silicon dioxide used in adhesives, can improve the bonding strength. The tensile strength and elongation of silica filler than not Ghana m respectively increased by 21% and 23%. 4, inkjet printing, and paper: With nano-sized silica coating material, form a tiny inorganic and organic composite particles, ink printing up, immediately absorbed by similar honeycomb micropore, its strong suction ink, coating for print part deep tonal, also can show very good levels; Dry quickly, coming out of the printer, you can directly touch; The coating material is very exquisite, not only high brightness, and can match the high-precision photo printing. Has a good waterproof performance, even in the water for a few hours, can remain the same. Its advantage is "3 tall one" that highlights, high waterproof and high ink absorption and quick drying. 5, color rubber: In soluble poly styrene butadiene rubber, adding a small amount of nano silica (instead of carbon black) as a reinforcing agent and the inhibitor, produce the color of the rubber products of toughness, strength, elongation, flexural and anti-aging properties are reaching or higher than epdm. 6, magnetic materials: Added in the iron coke powder is given priority to with nano silicon dioxide composite powder was modified, after testing, product performance to the highest levels of the existing products, such as remanence intensity is greater than 4100 Gs, intrinsic coercive force more than 3000 Oe, magnetic energy product is greater than 4 mGOe, significantly reduce the production cost of materials at the same time. In addition, nano silica can be widely used in ceramic (lining) porcelain, gypsum, storage battery, paints, adhesives, cosmetics, glass fiber reinforced plastic, chemical fiber, organic glass, environmental protection, and many other products in the field of the file to upgrade. Usage: Recommend the use of 1-5%, the customer can be tested according to the specific situation to choose the best addition amount. Packing: 10 kg/bag
