Analysis of airgel lower prices of raw materials will be reduced if

Insulation energy-saving materials in our early 80s really began to develop, from the beginning, and more development in the industrial field of application to be widely used in building insulation field, and its prospects even more ambitious. In this vibrant industry, Aerogels complex products but also because of its overall performance unmatched become the focus of attention, but the price is relatively airgel is relatively high, for this purpose, reporter interviewed the executive vice president of China Association of energy-saving insulation material, please adjust her from a professional point of view on current developments in thermal insulation and energy-saving materials airgel composite products in the future direction of development, and airgel prices. future broad space for development \”currently on the market mainstream energy-saving insulation material, basically in the 1980s began to develop, for example, rockwool , glass fiber and organic cotton materials are state-level new materials to promote the development strategy. airgel composite insulation products in the field of energy as a more promising products in recent years is attracting people\’s attention, but it is not an already complete mature products, \”Hu Xiaoyuan when it comes to energy-saving insulation materials industry, said:\” the development of the energy-saving insulation materials industry is not as mature cement and other building materials products, the scale of it from the market and are not a very mature products, in such a great country with 1.3 billion population country, the energy-saving insulation material far not been widely used throughout the industry, there is a very large room for improvement. \”According to Hu Xiaoyuan introduced China\’s first thermal insulation material Association of Energy focusing on work in the industrial field, and with the high level of technology and there is a growing requirement for energy-saving, energy-saving insulation materials have now been widely used in building insulation areas, two-thirds of the market is used in the construction insulation field. \”From the point of view the overall size, insulation material in the construction of energy-saving large amount of insulation applications, but its application and promotion in this area mainly in recent years began, especially in the course of building insulation mandatory requirements is still relatively short. From most start demands in building design, followed by the requirements, including the building housing the Department every year to check the implementation of standards in product application. the current people have attached great importance building energy question, insulation energy-saving materials the industry has a very good development prospects and great room for improvement.\”Hu Xiaoyuan said:\” adiabatic energy-saving materials wide range of applications, such as new energy vehicles, rail transportation, cold chain logistics, photovoltaic, clothing, sports equipment, energy storage, environmental protection and other fields. Energy-saving insulation materials are now expanding the application of the marginal line, this is a sunrise industry, composite airgel insulation products as a new type of energy-saving materials have much room for improvement. \”It is understood that airgel composite products currently under development and is more exploratory stage, and not really begin to industrialize use, and did not create a large-scale output. However, due to the composite airgel insulation products with energy-saving materials can not match the superiority of performance and explore the potential to be large, so that it has a high degree of attention of. overall performance can not be compared when a reporter asked airgel composite products currently on the market mainstream insulation What are the advantages when compared to the material, Hu Xiaoyuan said: \”airgel composite products compared with the thermal insulation material widely used on the market today, not to say that performance in some way better than other products, but its overall performance is superior . \”\” Among energy-saving insulation material widely used in the current market, some better thermal insulation materials, fire resistant materials, some better, some materials better water resistance, and some material has a unique advantage in one respect, but airgel composite material products able to put together these advantages, it is currently saving any kind of insulation material can not be done. \”Hu Xiaoyuan detail illustrates the superiority of airgel composite article material, for example among the thermal conductivity of the heat insulating material is an organic material saving is best among all materials, the thermal conductivity can be achieved as a polyurethane 0.019W / (m · K). However, it is because of its good thermal conductivity, high coefficient of combustion, fire flammable, which doomed it can not be used indoors. we current emphasis on increasing fire due to fire performance polyurethane material not great degree of restriction on the scope of its application. the same polystyrene foam (EPS) faced with this problem, the current field of buildings more energy-efficient, 70% EPS market, probably in its thermal conductivity 0.039 W / (m · K) , but the fire is flammable. 75% energy saving building and do, then cold areas in the northeast of this material will be made very thick accordance with state regulations, which restrict its application market is currently a lot of EPS market, but wantDue to reasons like getting its own limits, as well as new material into its future development will be limited or even shrinking of the market appear. Inorganic materials fire performance Class A fire can do well, but it\’s not good thermal conductivity, but also in its production process is bound to have been affected to consume a lot of energy and environment. Huxiao Yuan said: \”energy-saving materials among insulating materials in addition to these other materials are also faced with the problems, the advantages of this integrated airgel composite article is particularly the valuable.\” Rate of change of temperature coefficient of thermal conductivity of the airgel composite article curve unlike other insulating material such as saving with increased temperature has a zoom process, the thermal conductivity variation curve is relatively flat, like the pipe insulation effect of this on the market better than the current mainstream insulation effect of the insulation material. In the field of building energy generally measure the temperature between 25 ~ 75 ℃, but even airgel composite article to a temperature 600 deg.] C, the thermal conductivity can be maintained at 0.04 ~ 0.06W / (m · K), which highlights its advantage. Hu Xiaoyuan also said that a longer service life airgel composite product is unmatched by other insulation materials, insulation materials commonly used for maintenance will be carried out after a few years, replacement, and long product life airgel composite the reduced maintenance costs, more environmentally friendly energy, its stable thermal conductivity can reduce the thickness of the insulation material in cold regions, reducing the use of space.
