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..

 

 

 

 

 

Yuan Lei's Little Knowledge | Application of Wet Mica Powder in Rubber

2024-06-19


Wet mica powder is widely used, not only in coatings but also in rubber. Below, the editor will take you to understand the application of wet mica in rubber.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings

2024-06-12


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings

2024-06-04


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.
