【 Building materials network 】Recently, in the special glass production base of Hainan Zhonghang Special Glass Company, with the 15mm thick online low radiation coating (LOW-E) of Line 2 being super white and super thick Glass stay production line The world's first online LOW-E ultra white and thick glass line was born in China.

On the basis of international advanced technology and through independent innovation, Hainan AVIC Special Glass Technology R&D Team has increased the thickness of online LOW-E large plates from 3mm, 4mm, 5mm, 6mm, 8mm to 10mm and 12mm. Now it has successfully produced 15mm super thick glass. This is the world's current thick online LOW-E glass The product is also another innovative achievement of Hainan Zhonghang Special Glass after it developed online Low-E ultra white products. The appearance of online Low-E ultra white and ultra thick glass marks that the technology of China's glass industry has reached the international leading level, which is of great significance to further expand the international and domestic building energy-saving glass market, and is also a new contribution made by China's glass industry to the technological progress of the world's glass industry.

According to experts, due to the constraints of production technology, online Low-E Coated glass It is difficult to produce thick films. In many public buildings and most high-rise buildings, podium buildings, commercial buildings and lobby building decoration, a single piece of thick glass on the large panel is required. Because of the problem of off-line Low-e glass peeling, architects at home and abroad can only use ordinary glass in these parts all the time Float glass It is so thick that there is an inextricable contradiction between the building effect and use function and the building energy conservation.

On the other hand, online Low-E is a solution of 700C coating on the float line on the glass body. The film will never come off when a single piece is used. 15mm super thick glass can not only meet the requirements of load and wind resistance strength, but also be beautiful, solid, and has strong tempering processability. Its energy-saving film has the same low radiation performance as glass. When a single piece is used, it can be warm in winter and cool in summer. Its heat insulation effect is very significant, In winter in the north, the waste of indoor heat energy is greatly reduced, and in the south, it can play a good role in heat insulation and energy saving.

According to statistics, the heat transfer coefficient of single 15mm online LOW-E glass is 36% lower than that of ordinary float glass, and the energy saving efficiency is 1/3 higher than that of ordinary single glass. When applied in the construction field, it can save a lot of power and coal resource consumption. Moreover, the new product developed by Hainan Zhonghang Special Glass Co., Ltd. is online super white thick plate large-size Low-E glass, Ultrawhite glass It has a very high transmittance, and the visible light transmittance can reach 92%. It has very good optical performance and can more realistically reproduce the landscape. It is the dream of architects and owners of high-end office buildings and luxury hotels.

Through the combination with online Low-E film, the original high visible light transmittance of ultra white glass can be guaranteed, the indoor lighting requirements and comfort can be met, the indoor lighting power consumption can be reduced, and the low radiation function can be achieved to achieve the comprehensive energy-saving effect. It is to meet the requirement of high permeability building type key Materials, such as northern and coastal buildings At the same time, due to the strict requirements of ultra white glass on raw materials and its own low iron characteristics, ultra white Low-E glass will not explode spontaneously.

Used as lobby glass and Curtain wall glass As required by wind pressure resistance and design code Tempered glass Instead of super white tempered glass, the danger of self explosion of thick ordinary tempered glass is higher. Therefore, this new technology has also solved the problem of self explosion of tempered glass for buildings, which has been plagued for many years. This problem was once one of the representative proposals of the "two sessions" over the years, and has been highly concerned by all sectors of society

Hainan Zhonghang Special Glass Materials Co., Ltd., a subsidiary of AVIC Sanxin Co., Ltd., is a key enterprise of new defense materials in Hainan Province and AVIC Industry, and also an eye-catching enterprise of new materials in China's capital market. Located in the Old Town Economic Development Zone of Hainan Province, it has two world-class placers in Wenchang, Hainan. The enterprise has introduced a number of high-end float glass production and manufacturing know-how from Europe and the United States, and has more advanced CVD online coating production technology and equipment in the world. The company has four 600 ton Float glass production line , cars produced with full oxygen combustion production process and waste heat power generation Glass sheet Ultra thin electronic glass, ultra white float glass, ultra white aviation materials, high-speed train glass, and online low-radiation series energy-saving glass are the leading enterprises in high-end glass manufacturing in China.

Line 2 of Hainan Zhonghang Special Glass Company originally produced TCO solar substrate glass. After the solar energy market shrank seriously, the enterprise successfully transformed to produce online Low-E coated ultra white ultra thick glass through technological innovation. This product has provided the first opportunity for Hainan AVIC Special Glass to further open up the domestic and international markets, and has greatly improved the market competitiveness and economic benefits of the enterprise. This line can completely produce all kinds of online low radiation series 3-15mm energy-saving glass in various colors and ultra white, and it is also the first high-end energy-saving glass manufacturing line in the world. At present, the product has passed the inspection of the National Glass Quality Supervision and Inspection Center, and its performance indicators fully meet the technical requirements of the national standard Coated Glass Part II Low Radiation Coated Glass (GB18915.2-2002). This achievement has a very important strategic development significance for the R&D and innovation of China's second-generation float glass, the transformation and upgrading of the glass industry, the development of resource conserving, environment-friendly and high-quality * * glass industries, and the transformation of China from a big glass country to a strong glass country.
