Silicon micro powder is a product name, it is a new functional mineral raw material which composed of natural microcrystalline quartz.
Silicon micro powder ore is usually white, grey, the process performance is good, is extremely good raw materials for the preparation of processing high-purity ultrafine silica powder. Refined powder general use of the wet legal system for process, namely the run of mine ore through crushing, washing and scrub to get it, refined silica powder with high purity, white degree good, is indispensable inorganic mineral materials for precision electronics, aerospace, optical fiber, etc.
Why the use of silicon micro powder is extensive, because it is not only a common silica mineral physicochemical properties and uses, but also because of silicon micro powder structure characteristics and good processing property, such as nearly equiaxed grain, the ball degree is high, feel is exquisite, dispersed flow flat is good, oil absorption rate lower and so on, making it has more excellent functional characteristics and more extensive uses. Now the metal powder supplier summarizes the main purpose of the silicon micro powder is as follows:
Silicon micro powder in the application of rubber products: active silicon powder filling in natural rubber, butadiene rubber and rubber, the powder is easy to disperse, mixing process performance is good, rolling and extrusion sex good, and can improve the speed of vulcanized rubber vulcanization, rubber and improve viscous effect, especially superfine grade silicon micro powder, replacing part of the white carbon black filled in rubber, to improve products property index and reduce the production cost were having very good effect. Silicon micro powder used for exported medicinal chlorinated butyl rubber bottle stopper and used for electrical insulation rubber shoes, the effect is really good.
Silicon micro powder as filler in the imitation leather production, and the products of the strength, elongation, flexibility, etc. various technique indexes is better than that of light calcium carbonate, active calcium carbonate, the activity of pyrophyllite and inorganic material for filling agent production products.
Silicon micro powder instead of refined clay, such as light calcium carbonate powder material used in battery glue shell, filling quantity can reach 65%, and the process performance is good. The glue shell products, with smooth appearance, hardness, acid corrosion, voltage resistance, thermal deformation and impact resistance, and other physical mechanical properties can meet or exceed the corresponding technical index.
Silicon micro powder in the application of plastic products: the active silica powder is an ideal reinforcing agent for pp, PVC, PE and other products, not only have larger filling quantity, and tensile strength is good. Made of masterbatch, can be used in PVC floor tile, can improve the wear resistance of products. Silicon micro powder used in olefin resin film, its powder dispersion uniform, film resistance, good mechanical performance is strong, than by PCC do filling material production of plastic film, cut off infrared transmittance reduced by 10% or more, is extremely good for the agricultural shed film application promotion. It can also be used for electric wire electric cable outer covering, etc.
Silicon micro powder in the fusion system instrument glass and glass fiber application: because of silicon micro powder grain size is very fine, high purity, easy melting in the system of glass production, short time, products such as borosilicate glass instrument, soda-lime instrument glass, neutral vessel glass and other products of the physical and chemical properties and appearance quality reached the corresponding standards, at the same time, the production of energy saving effect is especially significant.
Moreover, on the basis of the silicon micro powder has the characteristics of fine granularity, uniform and specific surface area is big, used for glass fiber direct drawing new technology, and greatly improve the fiberglass mixtures of homogenization degree and speed up the furnace of vitrified speed. The stability of drawing is better than the glass bead wire drawing process, and has significant effect of energy saving and reduce the production cost. As energy saving mineral raw materials, silicon micro powder used in ceramic industry, have an idea effect on reducing firing temperature and improve the rate of finished products.

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.
