Silica nanopowders Features:
Nano silica has the features of small particle size, narrow particle size distribution, porous, large surface area and owns a large number of hydroxyl groups and unsaturated residual bonds on its surface and shows high reflectivity to long wave,visible light and ultraviolet ray.
Silica nanopowders Application:
1.Used in paint: on the basis of the original formulation of latex water paint, add silica nanopowders which made up of 0.3-1% of the total weight (fully dispersed). By adding SiO2 nanopowders, the performance of suspension stability, thixotropy of the coating, the strength of combination between substrate and coating and the degree of finish etc. has improved greatly. Also, the drying time is significantly shorten, the test time to artificially accelerate UV aging is multiplied, the scrub resistance increased from thousands of times to ten thousands of times and the stain resistance of the coating also improved significantly.
2.Used in plastic: Silica nanopowders is fully dispersed in polypropylene (PP), polyvinylchloride (PVC) plastic raw materials and can significantly improve strength, toughness, wear resistance and aging resistance of plastics. For example, nano modified PP, its performance in water absorption, insulation resistance, compressive residual deformation, flexural strength and other indicators all meet or exceed the engineering plastic nylon 6, and its weathering is more than doubled in some areas, and it can be an alternative to nylon 6 in some areas.
3.Used in color rubber: By adding a small amount of nano silica (instead of carbon black) in the solution polymerized styrene-butadiene and other rubber as reinforcing agents and anti-aging agent, the toughness, strength, elongation, bending and anti-aging performance of the color rubber products meet or exceed the EPDM.
4.Used in modified magnetic materials: Add silica nanopowders based composite powder into iron coke powder, the product performance reaches the highest level of the existing products according to the test. For example, the remanence flux density is more than 4100 Gs, inner intrinsic coercivity is greater than 3000 Oe and the magnetic energy product is greater than 4 mGOe, and the material production costs are significantly reduced at the same time.
5.In addition, nano silica can be widely used in the field of Tao (boring), porcelain, plaster, batteries, paints, adhesives, cosmetics, glass, steel, chemical fiber, plexiglass, and environmental protection to upgrade the quality.
Recommended Dosage:
There is a wide range of product application in different fields with a large different amount of dosage, from 0.5 to 5.5%. The end user shall determine the quantity to be added through testing and make the best dosage choice for the best use.
