1, ordinary quartz sand, which contain SiO297 %, Fe2O30. 04%, 1750 ℃, refractoriness exterior part of the larger particles, surface is yellow skin cyst.Particle size range 5-220 mesh, can be produced according to user requirements.The main application fields of common quartz sand are metallurgy, silicon carbide, glass and glass products, enamel, cast steel, water filtration, foam alkali, chemical industry, spray noise and other industries.
2, refined quartz sand: also known as acid washed quartz sand, containing SiO299%, fe2o30.005%, using high-quality natural quartz sand, after careful selection, fine processing.Particle size range 1-0.005mm, can be processed according to user requirements.The use of refined quartz sand is generally: making glass, refractory materials, smelting ferrosilicon, metallurgical flux, ceramics, grinding materials, casting quartz sand, etc., in the construction of the use of its has a strong ability to resist acid medium corrosion, acid resistant concrete and mortar.
3, high purity quartz sand: containing SiO299%, fe2o30.001%, using high-quality natural quartz stone, after careful selection, fine processing.Particle size range 1-0.005mm, can be processed according to user requirements.The purpose of high purity quartz sand is: high-grade glass, refractory materials, smelting ferrosilicon, melting stone, precision casting, ceramics, grinding materials and other aspects, quartz sand has a strong ability to resist acid medium corrosion, can be made into acid-proof concrete and acid-proof mortar.
4, silicon powder: including SiO296 %, Fe2O30. 3%, 1600 ℃, refractoriness appearance for gray or gray powder, bulk density of about 230 kg/m3.It is a fine powder made of natural quartz by crushing, ball grinding, flotation and other processes.The particle size range is 0.1-0.3 micron.USES of silica powder: dry mixed (pre-mixed) mortar, high-strength non-shrinkage grouting material, wear-resistant industrial floor, thermal insulation mortar, concrete preservative, water-proofing agent for cement-based polymerization;Reinforcement of rubber, plastic, paint, coating and other polymer materials, modification of ceramic products, etc.
With the demand of industrial production in the future, quartz sand will develop towards the method of high quality and fine fineness.It can be said that the future of refined quartz sand equipment and high purity quartz sand equipment development speed will be more rapid.
