Lianyungang, Silicon Flour Co., Ltd. purchased silicon fine powder ultrafine division production lin

General introduction

　　Lianyungang, a silicon micron powder, a Japanese company, a registered capital of 2.7 million US dollars. Located in 323 provincial road industrial concentration in Shihu Township, Donghai County, Jiangsu Province, a centralized location of high quality quartz.

　　Company was established on May 27, 2011. The main products have molten stone sand, molten silicon fine powder, soft composite silicon fine powder, high purity ultrafine silicon powder, activated silicon fine powder, crystalline silicon powder, spherical silicon fine powder, etc. Complete specifications.

　　Main uses: photovoltaic solar industry and electronic package materials, high temperature refractory materials, aerospace materials, quartz glass tubes, quartz ceramic rolls, and coated copper industries.

　　Silicon fine powder introduction:

　　Quartz powder (same as quartz sand) is also known as silicon fine powder, it is a hard, wear-resistant, chemically stable silicate mineral, The main mineral components are SiO2. The color of the quartz sand is milky white, or colorless translucent, hardness 7, brittle and brittle, shell-shaped fracture, oil gloss, stacked density (20-200 sterile 1.5), its chemical, thermal and mechanical properties have obvious Duration, insoluble in acid, slightly soluble in KOH solution, melting point 1650 ° C. The quartz stone produced from the mine is processed, and the product is generally referred to below 120 mesh (less than 120 mesh). More than 120 destination products are called quartz powder.

　　There are two kinds of production methods of quartz powder separation and water law, various conventional specifications: 100m, 150m, 200m, 325m, 400m, 600m, 1500m, and 2000m (M.). Alternatively, we can require a profile specification according to customer requirements, requiring a particle size distribution. 1

　　Dry production of quartz powder, main equipment has a sticker, pulverizer, vibrating screen, and the like. Its process flow is processed by the quartz stone. The stone is processed into a smaller stone, and the stone material is subjected to grain, and then passes through the vibrating screen sieve, and the magnet rod and the magnetizing iron are used in the screening process, and then dispensing Finished into the library.

　　Water method produces quartz powder, main equipment has a sticker, stone mill, baking room, vibrating screen, water system, etc. The process is approximately as follows: The quartz stone is processed into a small stone, and the stone material is crushed into sand. When the stone mill is crushed into a sand, the water is not stopped, and the water flows into the sand.In the starch, the grains in the sedimentation tank are then transported into the roasting room, and then the vibrating screen sieve is divided into the screening process, and the iron rod and the magnetizing iron are used to remove iron, and then the library is bracted. Dry-produced quartz powder is divided into ordinary quartz powder, refined quartz powder two levels. When the quartz stone mine was opened from the mountain, it brought yellowish epiderate. The product selected from the smaller quartz mine directly crushed the siened and used the ordinary quartz powder. It showed that Huang and white. The advantage is that the price is cheap, the disadvantage is more impurities, so most for the construction industry. Pick a big The minerals have been artificially removing the surface of yellow-brown outer skin, and then the process is refined, it is refined, and the apparent appearance is white, bright crystalline, like a white sugar. Because the processing process is expensive, the price is high.

　　The quartz powder produced by water law is divided into ordinary quartz powder and refined quartz powder. Process smaller quartz stone into ordinary quartz powder, process large quartz stone ore into refined quartz powder. Compared with dry quartz powder, the hydraulic quartz powder is due to the production process, less generates equipment iron and water, such as iron-containing, and impurities, less dry quartz powder, but due to its processing The price is high.
