Committed to the research and development, production and sales of three types of products: metal silicon, metal silicon powder and micro silicon powder
Classification knowledge of microsilica
Micro silica fume, I believe everyone knows and knows it, so, do you know its classification?
What to be careful with when handling microsilica
The fineness of micro-silica fume is less than 1μm, accounting for more than 80%, and the average particle size is 0.1-0.3μm, which is a gray state. Therefore, the bulk density is small, the natural inclination angle is large, fluffy, easy to fly, and difficult to store and transport. It is because of these characteristics that micro-silica fume manufacturers need to be more careful when handling them. So, what is the specific treatment process?
Silicon metal prices remain weak and stable
"FerroAlloys Online" 2022-1-5: In 2022, the metal silicon market will be calm, and various grades of metal silicon products show a weak and stable operation state, only a small drop of 500-100 yuan. At present, the low-grade 553# without oxygen is maintained at the ex-factory price of 19000-19200 yuan / ton, and the price of individual low-iron calcium products is about 300-500 yuan higher, and there is no decline. Products such as 3303# and 421# have dropped to between 21500-22500 yuan/ton, which has been stable for about a week.
Smelting process of metallic silicon
Silicon metal smelting is a high-energy-consuming production. my country's silicon metal production has a long history. With the tightening of national energy policies, the development of energy conservation and emission reduction, and the promotion of new energy, metal silicon smelting has become a primary product and Technology, many domestic emerging energy companies have built a series of circular industrial chains such as metal silicon, polysilicon, monocrystalline silicon, solar cells, etc., which will inevitably affect the development of my country's entire energy field and the application of new energy in the next few years.
Application of microsilica in building materials
With the development of the economy and the improvement of living standards, the development prospects of micro-silica fume are getting better and better. Silica fume is a white powder, the important thing is its properties. It can fill the gaps in the concrete and make the performance of the concrete reach a better state. This is also the reason why it can sell well in the market and has great prospects for development.
Use of micro silicon powder in thermal insulation materials
As a new raw material, micro-silica powder is widely used in thermal insulation materials. It plays an important role in the improvement of amorphous refractories. The performance of the body is as follows: 1. There are many pores in the traditional refractory material, and the micro-silica powder is filled in the pores, which increases the bulk density and reduces the porosity, and the strength can be obviously enhanced.
