Порошок мікрокремнезему, також називається кремнеземною золою або когезивною кремнеземною золою, є аморфним, порошкоподібний діоксид кремнію (SiO2) отримують з феросплавів при виплавці феросиліцію і промислового кремнію (кремній метал) collected by a specially designed dust collector. It is widely used in the processing and production of industrial manufacturing. Then there are many types of microsilica powder, and their specific uses vary. Сьогодні, I would like to briefly share with you the uses of different types of microsilica powder.
According to the different uses of microsilica powder, microsilica powder can be divided into the following categories: General microsilica powder, electrical grade microsilica powder, electronic grade microsilica powder, fused microsilica powder, ultra-fine microsilica powder, spherical microsilica powder, nano silica.
Ordinary Microsilica Powder
Application: used in epoxy resin casting material, potting material, electrode protection layer, metal casting, кераміка, silicone rubber, coating and other chemical industries.
Electrical grade microsilica powder
Application: used for insulation casting of common electrical parts, insulation casting of high-voltage electrical appliances, APG process injection material, epoxy potting material, ceramic glaze material, тощо.
Electronic grade microsilica powder
Application: mainly used for integrated circuits, electronic components of plastic sealing material and packaging material.
Superfine silica powder
Application: mainly used in coatings, фарби, engineering plastics, клеї, silicone rubber, precision casting ceramics.
Fused microsilica powder
The raw material used for fused silica micronized powder (WG) is natural quartz by high temperature melting, cooling the amorphous SiO2, through a multi-processing process to become a micronized powder. The product has high purity, low coefficient of thermal expansion, low internal stress, high humidity resistance, low radioactivity and other excellent characteristics.
Application: It is used in large scale and super large scale IC plastic sealing material, epoxy casting material, potting material, and other chemical fields.
Spherical microsilica powder
“Сферичний” silica micronized powder is made of high quality quartz ore and processed by unique technology to form a kind of high strength, high hardness and inert spherical particles. It has very low oil absorption rate, mixing viscosity and friction coefficient. Its unique spherical structure, compared with other angular quartz powder (silica micropowder), the powder fluidity is good, and the resting angle formed by the powder accumulation is small, so when mixed with organic polymer materials, it is dense and enhances the strength of the body. It is easy to disperse, evenly mixed, and can obviously increase the fluidity of the material.
Application: used in coatings, epoxy flooring, silicone rubber, тощо, significantly reduce the cost, significantly improve the performance of the processing of mixed materials.
Nano silicon dioxide
Mainly used in electronic packaging materials, polymer composites, пластмаси, покриття, гумовий, pigments, кераміка, клеї, glass fiber reinforced plastic, drug carriers, cosmetics and antibacterial materials and other fields, has become a new material for the upgrading of traditional products.
Depending on the raw material of silica, reducing agent or furnace condition, most of the micro-silica powder is gray or dark gray. In the formation process, due to the process of phase change by surface tension, the formation of amorphous spherical particles of amorphous phase, і поверхня відносно гладка, and some are agglomerates of multiple spherical particles stuck together.
