What is quartz?

Quartz powder is also called silica. Quartz sand has a high chemical stability and is hard. Its main component is SiO2. Quartz sand can be milky white, colorless or translucent. Hardness 7; brittle with no cleavage. Shape fracture, grease-luster, density of 2,65, bulk density (20 to 200 mesh is 1,5), chemical, mechanical, and thermal properties are clearly anisotropic, it’s insoluble in acids, but slightly soluble in KOH solutions, melting point is 1650. Quartz sand is the result of processing the quartz stone from the mine. It has a mesh size less than 120. The products with a mesh greater than 120 are known as quartz powder.

Use of quartz powder

Mineral fillers such as non-metallic minerals are used in modern polymer products like plastics, rubber and coatings. Addition of non-metallic minerals, such as the quartz powder, to the polymer material base can reduce costs, but also improve performance and dimensional stabilty, while giving the material special chemical and physical characteristics. Compression resistance, impact and corrosion resistance, fire retardancy, insulation etc.

KMPASS, etc. SlEC, a high-pressure epoxy molding material with good weather resistance and excellent electrical properties was developed using silicon micropowder. It is a material of choice for high voltage insulators and switches. KMPASS et al. Quartz powder was added to the patent of flame retardant insulating coateds in order to improve its thixotropic characteristics. The coating features uniform coating, no cracked, quick curing, and low costs. Liu You and other researchers added quartz to epoxy resin in order to develop an epoxy coating that is non-toxic and has anti-corrosion properties. It overcomes existing coatings’ shortcomings when it comes to brushing or spraying. KMPASS, etc. In the patented electronic insulation sealing film prepared by using butyl as the base material, adding silicon powder to it, the film has high strength insulation, is waterproof, resistant to heat, cold, chemical corrosion, ageing resistance, good plasticity and insulation. Good characteristics. Ideal for the insulation and sealing of wire busbars of 0.4-10kV and exposed joints in various electrical appliances.
