Source Lei small classroom | quartz sand supply capacity or become a bottleneck in the development of photovoltaic glass enterprises!


The raw materials for the production of photovoltaic glass mainly includeQuartz sand, feldspar, dolomite, limestone, soda ash, mirabilite, etc.Among them, quartz sand and soda ash are not only the main components of material input, but also the two types of raw materials that have the greatest impact on material cost.


According to the output of 100kg glass liquid, the material input is as follows:


Because photovoltaic glass has requirements for light transmittance, and the iron ions in quartz sand are easy to dye,Photovoltaic glass has strict requirements on iron content and must use low-iron quartz sand.


There are few sources of high-quality low-iron quartz sand ore that are easy to mine in China, mainly distributed inGuangdong, Anhui, Guangxi, Hainanand other places.


Therefore, some domestic companies have already started to lay out quartz sand. As early as 2011, Follett locked the ore resources of No.7 section of Shi Ying rock mine in Fengyang County, Anhui Province, with a reserve of 18 million tons, which can ensure the company's demand for quartz sand with a daily melting capacity of 2490 tons of photovoltaic glass for about 20 years and can stably supply quartz sand with high quality and low price for the company. Another giant Xinyi Light Energy's quartz sand mine in Beihai, Guangxi, will also supply the company in 2020.


In the future, with the growth of ultra-white embossed glass production capacity for solar cells, high-quality quartz sand with limited origin distribution will become a relatively scarce resource, and high-quality and stable supply of quartz sand is the guarantee for the development of photovoltaic glass enterprises.BecauseThis, the first-line tap has been in the reserve of mineral sources.so to speak,The ability to control quartz sand ore largely determines the competitiveness of photovoltaic glass enterprises in the future..






Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Source Lei gas barium sulfate ten uses


Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
