At present, China's urban construction market demand for the door industry has reached about 120 million m2, an increase of more than twice that in 1978, China has become the largest building door industry production country, a huge market potential. National Conference to develop building energy saving regulations in accordance with national building energy efficiency "Ninth Five" Plan and 2010 Plan, to determine the "95" to achieve the target of 50% of building energy efficiency, with the construction of new energy efficiency standards in China's major cities gradually implementation, energy-efficient door industry will continue to increase in our market. Market demand continues to expand. Our series door industry performance targets were met and exceeded the national performance standards, quality is the core competitiveness of products, in the spirit of faith and continuously improve product quality, our company has been committed to saving the structure and system combination door industry improvements to respond positively to the requirements of the State Council and the Ministry of Construction of the development of building energy-saving products, energy-efficient doors in response to trends in the application of industry trends, leading the trend. Promote the development of China's construction industry, to the consumer to create a comfortable environment. Eco-door into the building door industry energy industry is an important force in the door one of the important buildings external structure, plays a shelter, heat insulation, lighting and ventilation function and other aspects of people's working and living environment has an important role. Some say it is the eye of the building, is to beautify the room, one of the key parts of the outside of the building. For this reason, in order that our future production of door industry to achieve high quality water products, the struggle will be our future direction. Eco-door with a good performance, light weight, beautiful (with a metallic luster, can be processed into a variety of shapes and colors), good lighting (small box), durable (no aging, resistance to atmospheric corrosion), profiles easy to recycle and reuse rate, no environmental pollution and so loved by the people. However, its poor box insulation material performance characteristics affect the performance of ecological door industry door. Therefore, improving the energy performance of its insulation and eco-door technical issues to be addressed in the future focus is the development direction of my company's eco-door industry. An improved structure, diversification of the system design; To improve the performance and quality of existing door industry, the need to improve the structural design, a change in the past only the pursuit of labor, and material, the structure of low-level, low prices, in order to achieve the mainly to better performance of the sliding window casement main transition, to achieve single, double, triple and small open large fixed and other diverse system design. 2, focusing on the development in the field of raw materials; ① total material requirements of the box should be good strength, good thermal insulation properties, easy system to make all kinds of shape, but also easy to recycle and are environmentally friendly. To improve its ecological timber frame insulation, or composite bridge should be made of. ② glass should promote the use of hollow glass, and in the north should promote the use of Low-E type (Low-E) insulating glass. In the south, the sun radiant heat dominated areas, should promote the use of sun-coated glass. Developed countries have basically no single glass and white glass, because they are not conducive to saving and improving the living environment. ③ promote the use of double sealing and insulating glass with colored plastic made polysulfide insulating glass, insulating glass spacer bars should be continuous corner structure, if the four corners of plug-in joints must be sealed with butyl rubber . Single-sealed insulating glass is unavailable to do with silicone rubber hollow glass secondary seal is also undesirable because they are relatively short life. ④ Also called Shuangbo not available. Some window type in order to reduce the heat transfer coefficient, but also a low price, with a double glass that separated the two-story glass or with ordinary adhesive seal mounted on the window look, do not suck moisture sieve, only a single sealed. General impatience sealant aging, will not take long, it will into the gray dust, they can not wipe the impact of sight, very unsightly. Because that is the use of hollow glass polysulfide insulating glass made of plastic, if only a single sealed, then seal life there was only five years, the glass curtain wall specification expressly prohibit the use of, not to mention ordinary sealant, which even shorter lifespan. The most critical aspect is the life of the building project, namely durability problems. This is only a temporary expedient Shuangbo very undesirable. ⑤ In addition, the door on the building construction industry is also not advisable to use 5mm thick glass. Because 5mm thick glass used in the larger sub-grid area of ??the window, but also cause a safety issue to worry about. If you use it, it should be after the strength calculation, in ensuring the safety of the premise and then, must not be used indiscriminately. Kinds of accessories to ensure durable, easy to use and beautiful. Accessories door industry has an important influence performance, while plays an important decorative role, and therefore can not be ignored. Eco-door quality of the processing must be achieved; because the only way to make a good performance and good landscaping effect. Eco-door industry must establish actually product awareness, must stop the production of the body to resist the few low-quality products. To improve product insulation, sound insulation performance, must a lot to promote the use of environmentally friendly materials, insulating glass and high-quality accessories, but also widely used in many aspects of system design and development of the economic use, in line with China's national conditions of new products. Make become the mainstream in the 21st century eco-door door industry sectors.
