Safety valves are widely used in the field of polysilicon

safety valves are widely used in polysilicon enterprises. In recent years, Shanghai Wuyue pump has made this kind of emerging materials give full play to the role of reducing weight, strengthening materials and optimizing batteries. The safety valves produced by valve manufacturing Co., Ltd. are widely used in the field of polysilicon, among which many polysilicon enterprises in Anhui have used Shanghai Wuyue safety valve products

safety valves are widely used in polysilicon enterprises. In recent years, the safety valves produced by Shanghai Wuyue pump and valve manufacturing Co., Ltd. have been widely used in the polysilicon field. Among them, many polysilicon enterprises in Anhui have used Shanghai Wuyue safety valve products during construction. In the course of several years of operation, the safety valve provided by Shanghai Wuyue has never had quality problems, which has played an escort role in the normal production of these polysilicon enterprises

first of all, let's learn about the polysilicon industry. Polysilicon is a form of monocrystalline silicon. When molten silicon solidifies under supercooling conditions, silicon atoms are arranged into many crystal nuclei in the form of diamond lattice. If these crystal nuclei grow into grains with different crystal plane orientation, these grains combine to crystallize into polysilicon. Utilization value: it can be seen from the current development process of international solar cells that their development trends are monocrystalline silicon, polycrystalline silicon, banded silicon, and thin film materials (including microcrystalline silicon-based films, compound based films, and dye films)

Anhui Provincial Economic and Information Technology Commission issued the "access conditions for polysilicon industry" Gonglian electronic [2010] No. 137 document on December 31, 2010. In order to thoroughly implement the scientificoutlookondevelopment, standardize and guide the healthy development of polysilicon industry, resolutely curb repeated construction and overcapacity in the industry, in accordance with relevant national laws, regulations and industrial policies, optimize layout, adjust structure, save energy, reduce consumption, protect the environment According to the principle of safe production, the access conditions for polysilicon industry are specially formulated. Thus, many excellent polysilicon enterprises have also increased their investment and settlement in Anhui

polysilicon is the basic raw material in the upstream of the photovoltaic industry chain. The market price of polysilicon often fluctuates, directly affecting the fate of many photovoltaic enterprises and the development of the entire photovoltaic industry. At present, the price of polysilicon in China is "rising steadily", and the market prospect continues to be good. According to the data, the transaction price of polysilicon increased steadily from 11.78 yuan/ton at the beginning of March to 143600 yuan/ton at the end of April, an increase of 21.9%. Industry insiders told that there are two reasons for the rise in domestic polysilicon prices from March to April. First, demand has maintained growth from the beginning of this year to the end of April. On the other hand, affected by many polysilicon smuggling cases detected by the customs in April, the downstream demand for domestic silicon materials increased, and the tight supply of polysilicon became more obvious, resulting in an increase in the price of domestic polysilicon in April

the melting point of polycrystalline silicon is 1410 ℃ during its long-term research and development. Boiling point 2355 ℃. When it comes to high-temperature environment, high-temperature spring safety valves or high-temperature and high-pressure safety valves are generally installed on the pressure vessels of processing equipment. A48y-c and a48y-v types produced by Shanghai Wuyue company are special safety valves for high temperature and high pressure equipment. A48y-c high temperature and high pressure safety valve is applicable to temperature ≤ 425 ℃; A48y-v high temperature and high pressure safety valve is applicable to utility boilers, pressure vessels and temperature and pressure reduction devices with a temperature ≤ 550 ℃ as an overpressure protection device
