High purity silicon powderHigh purity silicon powder

Product Details

High purity silicon powderIt is an inorganic chemical, usually silica. Due to its ultra-small nano-scale size of 1 to 100 nm, it has many unique characteristics, such as UV optical properties, which can improve aging resistance, strength and chemical resistance to other materials. Has many uses. Nano-scale silica is an amorphous powder, non-toxic, odorless, non-polluting, fine, spherical, soft and reticulated semi-particle structure. It is insoluble in Sio2.

The main purpose:

Coating: Water-based latex paint. On the basis of the original formula, 0.3 1% of the total weight of nano silica (fully dispersed) is added after suspension stability thixotropy. The bonding strength between the coating strengths is strong, and the smoothness is high. High performance is obtained, such as shortening the drying time, multiplying the artificially accelerated UV aging test time by thousands of times, and at the same time thousands of times, the anti-fouling coating is significantly improved.

Plastics: Nano-silica is completely dispersed in polypropylene (PP) and polyvinyl chloride (PVC) plastic raw materials, which greatly improves the strength, toughness, wear resistance and aging resistance of the plastic. For example, the main performance indicators such as nano-PP, water absorption, insulation resistance, compressive residual strain, bending strength, all meet or exceed engineering plastic nylon 6, weather resistance products will be improved, and can replace nylon 6.

Colored rubber: a small amount of nano-silica (instead of carbon black), as a rubber-like water-soluble polystyrene intensifier and anti-aging agent. The performance toughness, strength, elongation, bending resistance and aging resistance of rubber products have reached or exceeded those of ethylene propylene rubber.

Magnetic material: The iron coke powder is modified by adding nano-silica-based composite powder after testing. The product performance is higher than the existing product. For example, the residual strength exceeds 4100 Gs, the inherent force is 3000 Oe, and the magnetic energy product exceeds 4 mGOe, while significantly increasing material costs.

In addition, high-purity silica powder is also widely used in the upgrading of environmentally friendly products such as ceramic (enamel) porcelain, gypsum, batteries, pigment adhesives, cosmetics, glass fiber, chemical fiber, and organic glass. (SiO2) or fused quartz (amorphous SiO2 after high temperature melting and cooling of natural quartz) processed by multiple processes such as crushing, ball milling (or vibration, jet milling), flotation, pickling purification, high-purity water treatment, etc. Micropowder.

High-purity silicon powder uses special processes such as crushing, purification, grinding, and classification to process natural crystalline quartz or fused silica into high-purity silicon dioxide powder.

Because high-purity silicon powder is widely used in electronics, microelectronics, electrical porcelain, metallurgy, paint, aerospace and other fields, the demand is great. Experts predict that in 2008, the global demand for high-purity ultra-fine silica powder products will exceed 1.5 million tons, and the domestic market demand will reach 250,000 tons. At present, my country's high-end silicon powder mainly relies on imports. With the rapid development of the electronics and microelectronics industries, the demand for high-purity silicon powder as a basic material will increase year by year.
