What is quartz sand?

Release date:2015-05-13 00:00 source: Click:

Quartz sand is made of quartz stone crushed by the processing of quartz particles. Quartz sand is a hard, wearable, chemically stable silicate mineral, the main mineral composition is SiO2, quartz sand color is milky white, or colorless translucent. Quartz sand classification industry will be divided into quartz sand: ordinary quartz sand, refined quartz sand, high purity quartz sand, fused silica sand and so on. Here we look at the block.

Ordinary quartz sand appearance part of the large particles, the surface of the yellow capsule. Particle size range of 5 to 220 mesh, mainly for metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, bubble flower alkali, chemical, spray noisy and other industries.

 Refined quartz sand, also known as pickling quartz sand, selected high-quality ore from the complex processing. Particle size range of 2-2500 mesh, the appearance of white or crystalline. Mainly used for advanced glass, glass products, refractories, smelting stone, precision casting, grinding wheel and other grinding wheel.

    High-purity quartz sand is the use of natural crystal or high-quality natural silica, carefully selected, fine processing from Its inherent molecular chain structure, crystal shape and lattice change law, so that it has high temperature, thermal expansion coefficient is small, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products Play an increasingly important role.

    Fused silica sand is the quartz by the capacitance method of production of amorphous SiO2, the appearance of colorless transparent block, particles or powder. It has very low thermal conductivity and excellent thermal stability, is the epoxy resin casting, electronic sealants, casting materials, refractories, ceramics and glass industry, the main raw material, but also paint coatings and other chemical industry ideal filling material.

Quartz sand has excellent performance and makes it more widely used. In addition, quartz sand also plays a huge role in water treatment. As a kind of modern water treatment equipment, quartz sand filter can effectively remove and remove suspended solids , Organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions, and ultimately to reduce the water turbidity, the effect of water purification.
