Silica for rubber prices

First, the rubber for silica powder Overview: A white powder secret of mineral raw materials from natural rubber with silica powder microcrystalline quartz ore by crushing, washing, grinding, drying, grading refining process, it has dispersed mobility Well, low oil absorption, delicate, uniform particles and so on. Tensile strength, tear resistance, anti-aging, acid, and has a reinforcing effect. Second, the use of rubber for silica powder: wear rubber products including rubber plates, tubes, belts, rollers, it requires having a good mix of penetration and strong adhesion, the test results show, filled with silica powder fully embodies the mix of plastic material thin, permeability, dispersion, and strong adhesion unique properties conducive mix obliterated and enhanced adhesion strength between the film and the canvas on canvas, products Mechanical properties of tensile strength, permanent deformation were significantly improved, especially in enhancing the wear resistance of rubber products. Rubber for silica powder is widely used: the field of rubber, paints and coatings, electronic packaging materials, silicon substrate, functional chemical fiber, functional plastics, advanced ceramics, special refractories, sealants, adhesives and chemicals, pharmaceuticals, pesticides, etc. . Third, the rubber for silica powder performance parameters: Product name commonly used mesh whiteness Mohs hardness Features rubber for silica powder 1250-500092 above 7 after filling compound thin, permeability, good dispersion, strong bond Mechanical properties of tensile strength of the product, the permanent deformation were significantly improved, especially in enhancing the wear resistance of rubber products. Fourth, the silicon powder used in rubber: To improve the physical and mechanical properties of rubber products, extend the life of rubber products, generally use two ways: one is the embedded reinforcing material in rubber products, such as fiber textile materials or metal material; the other is to add various fillers in rubber. Silica as a rubber reinforcing material has the following forms: (1) Powder Quartz. The main natural diatomite as raw material, crushing, calcination, remove organic impurities from used rubber to make rubber firm, and reduce the density of the compound, increase insulation properties, for the manufacture of insulating plastic material, model products and foam products for hard rubber can improve the softening temperature. (2) silica powder. Silica content of 75% to 79%, natural mineral mined, drying, crushing, screening is made, can be used for hose, belt and other rubber products, rubber padding easy kneading, dispersion, and can be filled with high dosage its rolled products smooth surface, its vulcanized rubber tensile properties nearly clay, and fairly light calcium; adhesion strength and ultimate permanent deformation than clay, wear resistance and elasticity than clay and light calcium; good aging properties, prices are lower than clay and light calcium. (3) quartz powder. Amorphous quartz powder, microcrystalline different types, from natural mineral grinding processing. Fifth, the rubber for silica powder PERFORMANCE: Our Silica for new rubber materials (silicon rubber, etc.): dispersion flow resistance, tear resistance, tensile pull, anti-aging, and reinforcing effect. Relative to the market in the low-end of precipitated silica, quartz powder SiO2 content (99.6%), moisture content (less than 0.1%), particle size, oil absorption and other major technical indicators are better than precipitated white carbon black. 1, the silicone rubber can improve the strength and quality of products (filling amount of 30 to 70%); anti-ultraviolet radiation, infrared reflection, the high dielectric insulating indispensable fine filler; 2, in the large size truck tires and car speed meridional filled rubber tire surface reaches more than 20% ultra-fine silica, the tire has good slip, heat, abrasion and other characteristics; the addition of ultra-fine silica powder to the tire tread can be significantly reduced after the tire rolling resistance enhance the tear resistance and cut resistance and strength, anti-ice and keep the tires skid resistance, known as the green tire. Europe and America are now widespread use of this tire. 3, after the addition of ultra-fine silica powder in tires and other rubber products, its flexibility, toughness, wear resistance and strength so much better than the conventional, ordinary silica filler made of tires and rubber products. 4, ultra-fine silica powder packed in natural rubber, butadiene rubber, nitrile rubber, rubber compound powder easily dispersed, good mixing process performance, rolling and extrusion is excellent, and can improve the cure rate of vulcanized rubber, Promotion rubber sticky, replace 50% of silica filled rubber compound, the mechanical properties of products (tensile strength, tensile strength, elongation at break, tensile permanent deformation, tear strength and product hardness, etc.) are no significant effect, but it can significantly reduce product costs, especially for the rubber roller, hose, wire and cable sheathing and other rubber products. Rubber reinforced with ultra-fine silica powder quartz powder to adjust the hardness silicone rubber, improved oil resistance, solvent resistance and processing properties of rubber vulcanizates, especially ultrafine silica powder quartz powder is added in the rubber, we could greatly reduce the cost of silicone rubber material. Therefore, ultra-fine silica powder quartz powder plays an important role in the silicone rubber. Anti-ultraviolet radiation, infrared reflection, high dielectric insulating indispensable excellent filler, and has good transparency.
