What is quartz powder?
Quartz powder (same as quartz sand) is also called silica powder. Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent. The hardness is 7, it is brittle and has no cleavage. Shape fracture, grease luster, the density of 2.65, Bulk density (20-200 mesh is 1.5), its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1650 . After the quartz stone mined from the mine is processed, the product with a fineness below 120 mesh (less than 120 mesh) is generally called quartz sand. Products with more than 120 mesh are called quartz powder.
Application of quartz powder:
In modern polymer materials such as plastics, rubber, and coatings, non-metallic mineral fillers occupy a very important position. Adding non-metallic mineral fillers such as quartz powder to the polymer base material can not only reduce the cost of polymer materials, but more importantly, it can improve the performance and dimensional stability of the material, and give the material some special physical and chemical properties. Such as compression resistance, impact resistance, corrosion resistance, flame retardancy, insulation, etc.
KMPASS, etc. used silicon micropowder as filler in epoxy molding compound and developed SlEC special high-pressure resistant epoxy molding compound with excellent electrical properties, excellent arc resistance, high pressure resistance, good weather resistance, and high surface resistivity. It is the material of choice for high-voltage insulators and high-voltage switches. KMPASS et al. added quartz powder to the patent for flame-retardant insulating coatings to improve the thixotropic properties of the coating. The coating has the characteristics of uniform coating, no cracks, short curing time, and low cost. Liu You and others added quartz powder to epoxy resin to develop a non-toxic epoxy toughened coating with anti-corrosion function, which overcomes the shortcomings and deficiencies of existing coatings in brushing and spraying at low temperatures. KMPASS, etc. in the patented electrical insulation sealing film, using butyl rubber as the base material and adding silicon powder, the prepared film has high insulation strength, waterproof, heat resistance, cold resistance, chemical corrosion resistance, aging resistance, good plasticity, and insulation. Good characteristics, suitable for insulation and sealing of 0.4~10kV wire busbars and exposed joints of various electrical appliances.
