Although quartz sand and molai sand both belong to the sand sub-category, the difference is very large. Today, quante Xiaobian will give you a detailed introduction to the differences between the two.
First, the product concept
Quartz sand is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral. The color of the quartz sand is milky white, or colorless translucent, with a Hardness of Mohs 7. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramic and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastics, rubber, abrasives, filter materials and other industries.
Moray sand is an aluminum silicate refractory material with a fire resistance of about 1750 degrees. The cast of pouring has the advantages of easy shelling, no deformation, no shrinkage, good finish and high yield. The higher the aluminum content in moray sand, the lower the iron content, and the smaller the dust, the better the quality of moray sand products.
Second, the production process
(1) Quartz sand is a quartz granule made of quartz stone by crushing and processing.
(2) Moray sand is sintered at high temperatures.
Third, the scope of application
(1) Quartz sand is an important industrial mineral raw materials, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, filter materials and other industries.
(2) Moray sand is generally used in stainless steel precision casting process.
Fourth, product classification
(1) Quartz sand is divided into: ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, silicon powder.
(2) Molai sand can be divided into: molai sand, molai powder.
