It is a non-toxic, tasteless, non-polluting inorganic non-metallic material, which is made of natural quartz or molten quartz by crushing, ball milling, flotation, pickling purification, high purity water treatment and other processes。Silicon powder used in paints and coatings (commonly used in: blending paint, primer, anti-rust paint, anti-corrosion paint, road paint, square paint, ship paint and other paints and coatings) can reduce the use of resins and dispersants in paints and coatings。It can not only play the role of filling, thickening and extinction, but also improve the fineness of paint, leveling performance, paint film hardness, arc insulation。 In the paint industry, the silicon powder of Haiyang powder shows the characteristics of fine particle size, high hardness, good suspension and dispersion, low oil absorption, high resistivity, based on these characteristics, the addition of silicon powder in the paint helps to improve the corrosion resistance, wear resistance, insulation and high temperature resistance of the paint。
1, in the field of concrete and refractory silica powder added to special refractory materials，A multi-layer protective layer is formed in oxidation，It has good mechanical properties and resistance to high temperature and oxidation，Special refractories are added with ultrafine silicon powder，The fluidity, sintering property, bonding property and porosity filling property are all improved to varying degrees。The structure density and strength are improved, the wear rate of the material is reduced, and the erosion resistance is enhanced。
2, the application of silicon powder in binders and sealants Silicon powder used in new binders and sealants can quickly form a network silica structure, inhibit colloidal flow, curing speed up, can greatly improve the bonding and sealing effect。
3, the application of silicon powder in the electronics industry Silicon powder used in electronic assembly materials, the main role is waterproof, anti-dust, anti-harmful gases, slow down vibration, prevent external damage and stabilize the circuit。The amount of high purity ultrafine and nano silica filled in epoxy plastic sealing electronic materials can reach more than 70 to 90%, so that it has excellent workability, small shrinkage, small thermal expansion coefficient, acid and alkali resistance and solvent insulation characteristics。
4, the application of silicon powder for plastics and modified resins Silicon powder applied to plastics, especially in the semi-transparent plastic film, after adding ultrafine silica, greatly improve its strength, enhance toughness, improve waterproof performance, energy storage and insulation performance。In the plastic structural materials, the mechanical properties can be increased by 1 to 3 times after the addition of silicon powder。For the modified resin matrix composite, it can improve the strength, toughness, elongation, wear resistance, finish, anti-aging and other properties of the composite。Silicon powder used in paints and coatings (commonly used in: blending paint, primer, anti-rust paint, anti-corrosion paint, road paint, square paint, ship paint, etc.) can reduce the use of resins and dispersants in paints and coatings。It can not only play the role of filling, thickening and extinction, but also improve the fineness of paint, leveling performance, paint film hardness, arc insulation。The effects of water resistance, anti-rust, anti-corrosion, anti-caking, anti-flow column, thixotide, anti-ultraviolet radiation, anti-aging and improving the storage stability of paint are more significant。
5, the application of silicon powder in rubber materials is used in new rubber materials (silicone rubber, etc.), which can make its excellent dispersion leveling, tear resistance, tensile resistance, anti-aging, and reinforcement。Compared with the middle and low-end precipitation method of white carbon black on the market, quartz powder is superior to precipitation method in SiO2 content (more than 99.6%), moisture content (less than 0.1%), product particle size, oil absorption and other main technical indicators。(1) can improve the strength of silicone rubber and product quality (filling volume 30-70%);It is an indispensable filler for anti-ultraviolet radiation, infrared reflection and high dielectric insulation.(2) The amount of ultrafine silica filled in the surface rubber of large truck tires and car high-speed radial tires reaches more than 20%，The tire has good anti-skid, heat dissipation, anti-wear and other characteristics;Because the addition of ultrafine quartz powder to the tire tread can significantly reduce the rolling resistance of the tire，Enhance tear resistance, cutting resistance and strength，Keep your tires resistant to ice and skid，They're called green tires。 (3) After adding ultra-fine silicon powder to other tires and rubber products, its elasticity, toughness, wear resistance and strength are significantly better than tires and rubber products with conventional and ordinary silicon dioxide as fillers。(4) ultrafine quartz powder is filled in natural rubber, butadiene rubber, butadiene rubber and other rubber materials，Powder easily dispersible，Mixing process performance is good，Excellent rolling and extrusion properties，And can improve the vulcanization speed of vulcanized rubber，Increase rubber viscosity，Replace 50% white carbon black filling in the compound，The mechanical properties of the product (tensile strength, constant elongation strength, elongation at break, permanent deformation at break, tear strength and hardness of the product, etc.) have no obvious effect，But it can greatly reduce product costs，Especially suitable for rubber roller, hose, wire and cable and its sheath and other rubber products，To be sure, nanoscale performance is better。
