The silica powder is a new functional mineral material from natural microcrystalline quartz. The microsilica ore is usually white or gray with excellent process performance.
It is an excellent raw material for processing of high purity ultrafine silica powder. The refined powder is generally prepared by wet process. That means the high purity and good whiteness refined silica powder is got by crushing, washing, scrubbing, ultrafine classification. It is an indispensable inorganic mineral material in the field of precision electrical, aerospace and fiber optics.
Microsilica has wider use because it not only has the physical and chemical properties and uses of common silica minerals, but also has structural characteristics of the silica powder and process performance, such as near equiaxed particles, ball high, feeling fine, dispersed leveling, oil absorption and low, making it had more excellent features and wider range of application.
Silica powder is an ideal enhancer for polypropylene, polyvinyl chloride, polyethylene and other products. It not only has a greater amount of fill, and tensile strength. Made masterbatch for PVC floor tile, you can improve the wear resistance of products. Silica powder used in the olefin resin film of its powder is uniformly dispersed, the film is good, strong mechanical properties, compared with plastic film to do with PCC filler production, blocking infrared transmittance above 10% reduction in agricultural greenhouse film applications to promote the very useful. It can also be applied in foreskin wire and cable fields by metal powder supplier.
Microsilica in the melting apparatus of glass and glass due to small particles of silica powder, high purity, easy to melt in the system for glass production, and a short time, products such as boron silicon instrument glass, sodium, calcium, instrument glass, neutral containers glass The physical and chemical properties of product quality and appearance of an appropriate standard, at the same time, the production of energy saving effect is particularly significant. In accordance with the silica powder has a fine grain size and uniformity, large surface area for glass fiber direct wire drawing process, greatly improve the glass batch are the degree and speed up the furnace the glass speed. Drawing of stability is better than a glass ball drawing process, and has significant energy savings and reduces the production cost effect. As energy mineral raw materials, silica powder used in ceramic industry, also received the desired effect of lowering the sintering temperature and improve the yield.
The microsilica doing polishing washing abrasive effect is better with the development of modern technology, the surface treatment of the material also requires more, the increasingly widespread application of abrasive. Microsilica because of its particles close to the circular, prepared ultrafine powder superfine, grading, after modification, the metal parts washing abrasive applications such as washing bearings, finish up more than 3.0, better than imports of similar products. In addition to the semiconductor industry, precision valves, hard disk, head polishing and car polishes all have very good results.
The microsilica applications in electrical insulation, packaging materials, electrical grade silica powder is an active silica powder, used as a filler of epoxy resin insulated packaging materials for electrical products, not only can greatly increase the amount of fill, and more important for lower hybrid the viscosity of the material system to improve the processing performance, increase the permeability of the mixture on high-voltage electrical coils in the lower expansion coefficient and the curing process of curing shrinkage, and reduce the mixture between the coils heat sheets, and improve the curing of heat, electricity, various aspects of mechanical properties play a useful role.
Applications of silicon powder in bonding and sealing gel preparation have promising prospects. With the technological progress and rapid economic development, microsilica applications will continue to become broaden. It should be noted that: the purification and ultra-fine processing of silica powder is essential to broaden its applications areas.Source:http://www.mhcmp.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
