Plate sand: the main raw material for the production of quartz stone plates

Quartz sheet is a benchmark product in the history of the development of artificial building materials. It has the properties of wear resistance, scratch resistance, heat resistance, corrosion resistance and durability. It has gradually become a new favorite in the home improvement market and is very popular among consumers. With the continuous development of the artificial quartz stone plate market, quartz sand, the raw material for the production of quartz stone plates, has also attracted much attention.

Compared with natural stone and other artificial stone plates, artificial quartz stone has dense structure, hard texture, no radiation, zero formaldehyde, moderate hardness and easy processing. It is widely used in interior decoration such as kitchens, bathrooms, public restaurants and other countertops. decoration area.

Artificial quartz stone plate is usually made of 95%~99% quartz sand or quartz powder, which is bonded and cured by resin, pigment and other additives. The quality of quartz sand or quartz powder determines the performance of artificial quartz stone plate to a certain extent.

Quartz sand and quartz powder are made from the mined quartz ore through crushing, screening, washing and other processes. Generally speaking, products with a fineness of less than 120MESH are called quartz sand, and products with a fineness of more than 120MESH are called quartz powder.

Quartz sand has high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties.

Quartz sand is made of quartz ore mined in mines through crushing, screening, washing and other processes.

For the sand washing process, different methods are adopted according to the quality of the quartz ore. If the ore quality is clean and the pollution is very low, ordinary water washing can be used. subsequent process.

Acid leaching is a kind of chemical purification of quartz sand, which uses quartz insoluble in acid (except HF acid), and other impurity minerals can react with acid to form soluble salts to purify quartz.

Quartz sand is an important industrial mineral raw material and plays an important role in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. Plate sand is ubiquitous in people’s lives today, which brings a lot of convenience to people’s lives. However, with the hot quartz sand market, high-quality quartz sand resources are becoming less and less, and quartz stone plate enterprises are faced with the problem of shortage of raw materials. Possessing high-quality raw material resources has become one of the core competitiveness of sheet metal enterprises.
