Heat insulation aluminium alloy profile gb is expected to come on stage in the industry

A few days ago, by the China standard design institute, China construction steel structure association jointly launch, the leading of the building insulation aluminum industry standard of the second stage demonstration held a grand meeting, the experts have come from the ministry of construction, industrial associations, xingfa and each large aluminum sliding door male company technical experts. The building insulation aluminium alloy profile “national standards, the promulgation of the construction industry in our country is about to fill heat insulation aluminium alloy profile of the national standard no blank. Heat insulation aluminum industry in 2008 gb is expected before the end of the year to come.

 

The formulation of the national standard, is the United States and Europe to production enterprise of actual investigation results and heat insulation profiles domestic relevant unit to domestic and foreign products for the standard argument, in building insulation aluminium alloy profile on many performance index have specific provisions, such as temperature, aging sex, group outfit geometric parameters are, and so on. For building insulation aluminium alloy profile of gb come on stage, the ministry of construction of China construction steel association HuangQi experts said, on one hand the promulgation of the gb mean that consumers will in future can buy energy-saving effect better heat insulation aluminum products, on the other hand, means that the building insulation aluminium alloy profile manufacturers of technical threshold will greatly raised, the heat insulation aluminium alloy profile for the construction market and prevent the appearance of inferior product has the important meaning.

 

According to information, with China’s rapid economic growth, the energy demand and increasing year by year, total energy consumption of building energy consumption in the total social accounts for about 30% ~ 40%, and among them building doors and Windows and focus the energy consumption, and aluminium folding door extrusion profiles in the building process in the use of indirect energy consumption in a surprising amount, guangdong xingfa r&d department chief, says dr WuXiKun, aluminium alloy profile is the weakness of the heat transfer coefficient than wood, steel, plastic is on the high side, thermal insulation performance is poorer, go against energy conservation, the extent of aluminium alloy profile hindered the development, in order to overcome the deficiency of the aluminum alloy material itself, and promote the development of the industry, the ministry of construction on the initiative of, guangdong xingfa aluminium leading and invite industry peers for together “architectural heat insulation aluminium alloy profile” standard, the standard come on stage, will be good for standard building insulation aluminum industry development direction.

 

As a huge development potential of the new heat insulation materials, heat insulation aluminium alloy profile at ease market appear, has been to the faster speed development. Now, heat insulation aluminum alloy doors and Windows with its remarkable advantage has gradually become the mainstream of the first choice in north China building doors and Windows. Beijing a surname Yang’s stylist to tell a reporter, heat insulation aluminum heat insulation, sound insulation with characteristics, to environmental protection, energy requirements, and these features is in line with international and domestic policies. The so-called heat insulation aluminium alloy profile, that is, by the aluminium alloy profile in the outer layer of the low thermal conductivity of middle nonmetal heat insulation materials linked to “heat insulation bridge” of composite materials, hereinafter referred to as heat insulation profile. Heat insulation materials for the production method basically has two kinds, one kind is to use heat insulation materials and article aluminum, by mechanical drive teeth, wear a rolling process, and form the “heat insulation bridge”, and called heat insulation profile “wear a type”; The other is the heat insulation materials poured into the body cavity insulation aluminium alloy profile, after curing, remove the metal forming process such as the “heat insulation bridge”, called “pouring type” heat insulation profile. Heat insulation materials for the inside and outside, could be different sections of profiles, also can is different with different ways of surface treatment color profile. But the region, the influence of climate, avoid the heat insulation materials and aluminum steels are the difference, when in heat bilges cold shrink between stress and produce larger gap; At the same time heat insulation materials and aluminum combination as a body, in doors and Windows and curtain wall structure, the same as stress and aluminium. So, ask heat insulation materials must also have and aluminum alloy extrusion profiles which are similar to the tensile strength, flexural strength, expansion coefficient and elastic modulus, or it will make heat insulation bridge was disconnected and destruction. Therefore, the selection of heat insulation material is very important. Heat insulation profile is applied to a new generation of environmental protection and energy saving aluminum alloy doors and Windows, mainly is aims at the traditional high thermal conductivity aluminum alloy, stays bad, the product of a single this key technical problems, the heat insulation profiles of insulating glass is made of a new type of doors and Windows, basically have the following advantages: one is the energy saving, prevent condensation. The heat conduction coefficient K value of 3.0 the following, effectively prevent the doors and Windows of indoor and outdoor heat conduction, can save energy 45% above, and indoor door window surface temperature and close to room temperature, and to reduce the interior for water supersaturated and of generation doors and Windows the knot shows a phenomenon.

 

2 it is environmental protection, comfortable. The different thickness of hollow glass and heat insulation aluminum multi-cavity structure of, can effectively reduce the sound waves of resonance effect, prevent the transmission of voice, build a peaceful, comfortable bedroom environment. Saving power at the same time, can reduce air conditioning and heating set for use, and aluminum alloy can reclaim recycle, no pollution, it is favorable to the environment protection. Three is watertightness, good air-tightness. New aluminum sliding Windows using the rain the design, make its of wind and air tightness can reach a level, for Ⅰ-Ⅲ watertight performance level. Four is adornment performance. Heat insulation profiles with different surface of surface treatment methods, match with different colour, decorate an indoor and outdoor different styles of decoration effect. A combination of the heat insulation and profile is a new generation of environmental protection and energy saving door window materials ideal.

 

Concerned expert points out the building insulation aluminium alloy profile “standard issued, not only will promote the development of the industry of aluminium alloy profile, also accord with” construction save social “strategy, and as a leading enterprise xingfa aluminium, also reflected the standardized construction process in the position and be used. The chairman ROM. Sue says xingfa aluminium, the building insulation aluminum sliding doorprofile “standards must be popularity as early as possible, again good standard someone has to carry out, so that the industry will accelerate the speed of the survival of the fittest, comprehensively promote our country building, the heat insulation aluminium alloy profile of the overall level.
