High-purity polysilicon is the basic raw material for the electronics industry and the solar photovoltaic industry. In the next 50 years, it is impossible for other materials to replace silicon materials and become the main raw materials for the electronics and photovoltaic industries. 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. The world's production of polysilicon in 2005 was 28,750 tons, of which 20,250 tons were semiconductor grade and 8,500 tons were solar grade. The demand for semiconductor grade is about 19,000 tons, which is slightly surplus; the demand for solar energy is 15,600 tons, which is in short supply. In recent years, the global solar cell production has increased rapidly, directly driving the rapid growth of polysilicon demand. Global polysilicon is oversupplied by oversupply. Affected by this, the price of polysilicon, which is the main raw material of solar cells, has risen rapidly. China's polysilicon industry started in the 1950s and industrialized in the mid-1960s. By the 1970s, the number of manufacturers had grown to more than 20. However, due to the backward technology, serious environmental pollution, high consumption, high cost, etc., most enterprises have lost their production or switched to production. So far, the domestic units with polysilicon production conditions include Luoyang Zhongsi High-Tech Co., Ltd., Handan Semiconductor Materials Factory, Sichuan Xinguang Silicon Industry Technology Co., Ltd., and Asia Silicon (Qinghai) Co., Ltd. The demand for polysilicon in China's integrated circuits and solar cells is growing rapidly. In 2005, the IC industry needed about 1,000 tons of electronic grade polysilicon, and solar cells required about 1400 tons of polysilicon. By 2010, the annual demand for electronic grade polysilicon in China will reach about 2,000 tons. The annual demand for photovoltaic grade polysilicon will reach about 4,200 tons. There is a serious gap in the independent supply of polysilicon in China. More than 95% of polysilicon materials need to be imported, and the supply is subject to long-term supply. Coupled with the skyrocketing price, it has already jeopardized the development of many enterprises downstream of polysilicon and has become a constraint to China's information industry and photovoltaic industry. The bottleneck of industrial development. As the demand for polysilicon continues to increase, the market has seen a boom in polysilicon projects, spurred by the increase in market gaps and rising prices. The investment boom of polysilicon projects can be said to be the inevitable result of the rapid development of the solar cell market. However, China's silicon materials industry must be carefully developed and cannot be rushed to the top; the key is to master the core technology, otherwise it will be difficult to get rid of the situation of being controlled by people. As a high-tech industry, the use of silicon ore to develop polysilicon has a large energy consumption and high power demand. At present, electricity prices have become one of the bottlenecks that most Chinese silicon mining companies need to break through. Therefore, China is vigorously developing the polysilicon industry, and it is urgent to formulate preferential tariff policies and reduce costs in places where conditions are ripe. Due to rapid increase in demand, but limited supply growth, the supply of polysilicon source is expected to be the most severe year in 2007. It is estimated that by 2009, the annual demand for polysilicon in the world will reach 65,000 tons. In the next three to five years, during the "Eleventh Five-Year Plan" period in China, it will be a golden period for the rapid development of China's polysilicon industry.
Ec-spd dimming glass is a new type of electronically controlled tinted light glass developed and produced by using SPD (suspended particle) photosensitive characteristics. It can replace curtains and adjust the light and shade permeability effect, allowing users to freely choose their own indoor light. Hot melt glass, also known as crystal stereoscopic art glass or molten glass. It is the use of glass thermal processing technology, flat glass burning melting, depression into the mold, made into a variety of shapes.
Rear Projection Film imaging is adopted, and the projection effect is very outstanding. The appearance of the partition Smart Laminated Glass is good. Different from the traditional partition materials, the use of Pdlc Film Roll allows our consumers to have a better partition appearance. PDLC Smart Glass Film is a Smart Film Roll that encapsulates liquid crystal molecules in a polymer with a self-adhesive layer.
The installation of the Self-adhesive Film For Glass Door is a technical task. If there is a little carelessness in pasting, air bubbles will appear between the Custom Switchable Film and the glass.
