Quartz powder (same as quartz sand) is also known as silicon micropowder. Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO₂. The color of quartz sand is milky white or colorless and translucent. Mohs hardness is 7. It is brittle and non-cleavable. , shellfish-like fracture, grease gloss, density of 2.65, bulk density (15-200 mesh is 1.5), its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 °C. After processing the quartz stone from the mine, the product with a fineness of less than 120 mesh (less than 120 mesh) is called quartz sand. More than 120 mesh products are called quartz powder. Quartz powder overview
Quartz powder physicochemical properties (same as quartz sand), also known as silicon micropowder.
Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO₂. The color of quartz sand is milky white, or colorless and translucent. Its hardness is 7. It is brittle and has no cleavage. It has a braided fracture, grease gloss, density of 2.65, bulk density (15 to 200 mesh 1.5), chemical, thermal and mechanical properties with obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1650 °C.
After processing the quartz stone from the mine, the product with a fineness of 120 mesh or more (less than 120 days) is called quartz sand. Products with more than 120 mesh are called quartz powder.
Quartz powder dry method and water method, various conventional specifications: 120M, 200M, 260M, 325M, 600M, 800M, 1000M and 2000M (M for mesh).
Uses: manufacturing glass, refractory materials (furnace), smelting ferrosilicon, coatings, rubber fillers, metallurgical fluxes, ceramics, honing materials, metal surface treatment, etc, which have strong anti-acid medium etching ability in construction. , to prepare acid-resistant concrete and acid-resistant mortar. Quartz powder dry method and water method:
1. Dry production of quartz powder.
The main equipments are stone crusher, pulverizer and vibrating screen. The process is that the quartz stone mineral material is processed into a smaller stone by a gangue machine, the stone material is processed by the pulverizer, and then sieved by a vibrating sieve, and the magnet rod are used to remove iron in the sieving process, and then the sifting is carried out.
2. The production of quartz powder by water method
The main equipment is stone machine, stone mill, baking room, vibrating screen, water system.
The process is roughly as follows: the quartz stone ore material is processed into a smaller stone by a gangue machine, and the stone material is crushed into sand by rock crushing, and water is continuously added during the rolling, the water flows into the sedimentation tank with the sand, and then the sedimentation tank is placed therein. The sand is transported into the baking room and baked into dry sand, and then sieved through a vibrating sieve. During the screening process, the iron rod magnet are used to remove the iron, and then the filling is completed and stored.
The dry-processed quartz powder is divided into two grades: ordinary quartz powder and refined quartz powder. When the quartz stone mineral material is mined from the mountain, it has a yellow-brown skin. The products that are directly crushed and sieved by selecting smaller quartz stone minerals are called ordinary quartz powder. The appearance is color and white. The advantage is that the price is cheap, and there are many disadvantages magazines. Therefore, it is mostly used in the construction industry to select large mines. The material is artificially removed from the surface of the yellow-brown skin, and then processed to produce refined quartz powder, which has a white appearance. Due to the time and expense of the processing process, the price is higher.
The quartz powder produced by the water method is divided into ordinary quartz powder and refined quartz powder. The smaller quartz stone mineral material is processed into ordinary quartz powder, and the larger quartz stone mineral material is processed into refined quartz powder. Compared with dry quartz powder, water quartz powder is less likely to produce equipment iron and water to wash away impurities during the production process. For example, iron content and impurities are less than dry quartz powder, but it costs more labor for processing. Material, so the price is higher.Quartz powder is not graded, only specifications. Because of its high whiteness, no impurities, low iron content, it has a wide range of applications.
