With the rapid development of information technology and solar energy industry, the global demand for polysilicon is growing rapidly, and the market is in short supply. my country is a potential market for organosilicon products, and the consumption of organosilicon monomers in my country has gradually increased in recent years. However, both polysilicon and organic silicon have the problem of conveying silicon powder in the production process. According to the characteristics of pneumatic conveying silicon powder, the valve needs to ensure its high degree of sealing and erosion resistance and wear resistance. At present, under the premise that the production process has not been greatly improved and optimized, choosing the appropriate valve is the main choice.
