Description:20-30nm hydrophilic SiO2 nanoparticles 1. Features of hydrophilic SiO2 White powder, non-toxic, odorless, and non-polluting; small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, and good dispersion performance; it has superior stability, reinforcement, and thickening And thixotropy. 2. Applications of SiO2 Nanoparticles Silicon dioxide nanopowder *Resin composite Fully and uniformly dispersing nano-silica particles into the resin material can comprehensively improve the performance of the resin-based material. Including: A to improve the strength and elongation; B to improve wear resistance and improve the surface finish of the material; C anti-aging performance. *plastic The use of nano silica for light transmission and small particle size can make the plastic more dense. After adding silica to the polystyrene plastic film, it can improve its transparency, strength, toughness, waterproof performance and anti-aging performance. Use nano-silica to modify ordinary plastic polypropylene, so that its main technical indicators (water absorption, insulation resistance, compression residual deformation, flexural strength, etc.) all meet or exceed the performance indicators of engineering plastic nylon 6. *coating It can improve the coating's poor suspension stability, poor thixotropy, poor weather resistance, poor scrubbing resistance, etc., greatly improve the bonding strength of the coating film and the wall, increase the hardness of the coating film, and improve the surface self-cleaning ability. *rubber Silica is known as white carbon black. After adding a small amount of nano-SiO2 to ordinary rubber, the strength, abrasion resistance and aging resistance of the product reach or exceed high-end rubber products, and the color can remain unchanged for a long time. Nano-modified color EPDM waterproofing membrane, its abrasion resistance, tensile strength, flexural resistance, and anti-aging properties are significantly improved, and the color is bright and the color retention effect is excellent. *Antibacterial material Utilizing the huge specific surface area, surface multi-mesoporous structure, super adsorption capacity and unique physical and chemical properties of nano SiO2, functional ions such as silver ions are uniformly designed into the mesopores on the surface of nano SiOX to develop efficient, durable, and durable The high-temperature, broad-spectrum antibacterial nano-antibacterial powder can be widely used in bills, medical and health, chemical building materials, household appliances, functional fibers, plastic products and other industries.Storage Condition:Hydrophilic Silicon Dioxide Nanoparticles should be stored in sealed, avoid light, dry place. Room temperature storage is ok.SEM  :
