Quality index of silicon metal powder
Silicon metal powder factory established for many years, to the market launched a large number of high-quality silicon metal powder, but also with reliable quality, thoughtful service, won the recognition of many users. In order to return the efforts of the majority of users for many years, but also in order to let more people know about the silicon metal powder, further promote the development of the industry, the silicon metal powder will be briefly introduced. Metal silicon powder can be used as carburizing agent or combustible agent according to different applications, which is a non-renewable resource. Not every kind of pure metal silicon powder can meet the standard, the following to introduce the quality index of stone metal silicon powder.
1, the formation of coke spheres, porous structure such as spongy, large spherical formation of coke, dense structure such as fibrous or acicular, its quality is better than sponge coke. In the mass index, true density represents this property roughly, and high true density indicates good crystallinity.
2, considering the reaction coke containing powder coke and block particle coke, the relative content of coke available.
3. Sulfur and ash content in oil tar. High sulfur coke will lead to products in graphitization gas bulge, resulting in cracks in carbon products. High ash content will hinder the crystallization of the structure and affect the performance of the carbon products.
4, coke products in the sudden rise to high temperature or from high temperature sharp cooling thermal shock resistance to crack performance.
Can through the above several aspects, to judge the quality of silicon metal powder, of course, in the determination of silicon metal powder, but also to consider the oil content, transparency, color, gloss, thickness, elasticity, chemical solvent, resistance to medium performance, impact resistance, scratch resistance, wear resistance, etc.. Silicon metal powder manufacturers welcome new and old users to contact our company, the contact information can be directly log in our company's official website for consultation, on the other hand can directly call the hotline to discuss cooperation, no matter which way, our company will try our best to meet your needs.
