Figure 1 Some common glass processing tools In recent decades, the continuous development of specialty glass has made it significantly different from traditional glass. Table 1 Special glass and traditional glass contrast glass industry is an industry that is both indispensable for scale efficiency and product structure advantages. In today's world, 61% of glass production is occupied by five major glass companies, and China's share of the world's total glass production of 31% is scattered in nearly 300 large, medium and small enterprises, and can not compete with the world's five major group companies. Therefore, the merger and reorganization of glass enterprises should be promoted through mergers, acquisitions, joint ventures, leasing, holdings, etc., and large-scale glass group companies should be developed to participate in market competition with low-cost, high-quality and multi-variety strengths. The way out for the glass industry. 
Figure 2 Distribution of application fields in China's glass industry It is understood that China's special glass has shown a favorable situation in recent years. In July 2003, Jiangsu Huaerrun Group invested 800 million yuan of special glass project to start construction; in October, Qinhuangdao Xingjian Special Glass Co., Ltd. produced space for anti-irradiation glass cover sheets, which was used for solar energy of China's "Shenzhou" series of spaceships. On the battery array, it becomes a barrier to the radiation in the outer space. The space anti-irradiation glass cover piece adopts unique formula design and adjustment technology, smelt the quality glass base block, introduces semiconductor processing technology into the glass finishing process, and has a breakthrough in performance efficiency ratio. The high-precision processing technology guarantees the glass. Quality, products are at the leading level in China. It is reported that this product is not only suitable for spacecraft, but also widely used in the anti-irradiation field of space satellites. 
Figure 3 The Long March 2f launch vehicle carrying the Shenzhou spacecraft On December 8, 2005, the two largest special glass production lines in the west were completed and put into operation in Shuangliu County. These two world-class production lines can produce 400,000 tons of special glass annually. The products are widely used in optical, electronic, information, automotive and other fields, and the construction industry has ended the history of Sichuan's automobile windshield production. 
Figure 4 Special glass production line On August 15, 2006, the successful high-borosilicate special glass technology project at the “6·18†fair meeting in Yongding County was officially established in Fujian Longfa Special Glass Co., Ltd. in the Lotus Industrial Park of Yongding County. Put into production. It fills the gap in the production of special glass in our province. "3.3 borosilicate glass production technology" has a very low thermal expansion coefficient, good thermal stability, high hardness, high abrasion resistance, excellent resistance to water and acid, and is widely used in the manufacture of heat-resistant glass instruments. , burners, industrial products and a large number of solar vacuum tube hot water pipes. In 2007, a private enterprise in Shantou City stood out from the competitive bidders of the strong hand, and won the bid for the construction of the special glass supply for the Olympic construction project, the “Bird's Nestâ€. The "Golden Glass" adopts energy-saving and heat-insulating coated glass as the base material, which not only meets the requirements of energy saving and environmental protection, but also complements the style of the Bird's Nest, and has received high praise from relevant experts at home and abroad. 
Figure 5: The main venue of the 2008 Beijing Olympic Games - Bird's Nest On September 4, 2008, the National Industrial Glass and Special Glass Standardization Technical Committee was formally established in Suqian City. It is proposed to formulate medium and long-term standardization work plans for industrial glass and special glass standard committees, establish a sound standard system, strengthen the implementation and supervision of standards, and conduct follow-up investigation and effect evaluation of published standards. This also marks the rise of China's special glass management system to a new height. In 2009, a large number of special glass manufacturing projects, such as the new single glass melting furnace with the largest melting area and the highest technical content, were officially put into production. In 2010, the National Special Glass and Silicon Materials Inspection Center started construction in Binhu New Area on the west bank of Longlongzi Lake. The entire testing laboratory put forward higher requirements in equipment, testing capability, technical level, scientific research conditions and management. . In 2011, with the introduction of the "12th Five-Year Plan for New Materials" and the "Twelfth Five-Year Development Guidelines for Building Materials Industry", special glass such as solar glass was mentioned in the new development schedule. In 2012, the State Council issued the “Twelfth Five-Year Plan for Strategic Emerging Industry Development†and proposed to develop inorganic non-metallic functions such as low-emission coated glass, photovoltaic ultra-clear glass, flat panel display glass, new ceramic functional materials, and piezoelectric materials. General guidance on the material. . . With the sustained and healthy development of China's economy, the consumption power of residents has been continuously improved, and the demand for glass deep-processing products has also been continuously improved. People's pursuit of products follows the simple use of functions to continuously upgrade, and more pursues the product's decorative, higher technology content and functions in energy conservation and environmental protection. In the future, as the economy continues to develop, the real estate industry and the emerging solar industry will continue to develop in the long run, and the industry will also face a better development opportunity.POLYKEN Visco-elastic anticorrosive tape is a new-type high-performance viscoelastic polyolefin material.
