Fangchenggang Quartz Sand Industrialization
With 5-480 mesh size range, according to user requirements production
, white or crystalline appearance. Main use: Advanced glass and glass products, refractory materials, melting rock type, precision casting, grinding wheels and other materials.
Quartz sand is a hard, wear-resistant, chemical properties and stability of silicate minerals, the main mineral component is SiO2, quartz sand color is milky white, or colorless translucent shape, hardness 7, no cleavage of brittle, shell shaped fracture, oil sheen, density 2.65, packing density for the 1.6,20-200 mesh 1-20 mesh 1.5, its chemical, thermal and mechanical properties have obvious anisotropy, do not dissolve in acid, slightly soluble in KOH solution, melting point 1750 . Quartz sand the unique physical and chemical properties, making it in the aviation, aerospace, electronics, machinery, and today's fast-growing IT industry occupies a crucial position, especially its intrinsic molecular chain structure, crystal shape and lattice variation so that it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion-resistant, piezoelectric effect, resonance effect, as well as their unique optical properties, in many high-tech products is playing an increasingly important role, Fangchenggang quartz sand Alliance .
Refined quartz sand: SiO2 99-99.5% Fe2O3 0.02-0.015%, selected high-quality complex ore processed.
Quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive and other industries. Can be steam-transports, rail transport, water transport. Industrial production is generally 50KG or 25KG bag packaging and export of tons. Common Specifications :0.5-1 .0 mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (Mm to mm units) have a higher fire resistance of quartz, industrial quartz sand will often be divided into: ordinary quartz sand, fine quartz sand, high purity quartz sand, fused silica sand and silica fume and so on.
High purity quartz sand: SiO2 99.5-99.9% Fe2O3 0.005%, is used 1-3 grade and high-quality natural crystal stone natural stone category, have been carefully selected and fine processed. Particle size range 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements.
Significant reduction in the sprayed concrete and pouring gray floor material to enhance the thickness of a single spray. High-strength concrete is a necessary element of the existing concrete engineering applications. With about the effectiveness of cement-fold in ordinary concrete, and low cement castable applications can reduce costs to improve durability. Effectively prevent the occurrence of alkali-aggregate reaction of concrete to enhance the compactness of casting refractories. With the co-existence, the more easily generated mullite phase, so that high-temperature strength, thermal vibration enhancements.
