For the insulation decoration board, almost everyone in the industry knows that people outside the industry may be relatively unfamiliar. Do not understand the heat insulation decoration board also does not matter, below, Boen environmental protection with everyone to understand in detail. The traditional heat insulation materials are mainly to increase the voids of the gas phase and reduce the thermal conductivity and conduction coefficient. In order to increase heat transfer and radiation heat transfer in the application environment, the fiber insulation material must have a thick overlay; The type of inorganic insulation materials to be assembled construction, there are many joints, damage to beauty, poor waterproof, short service life and other defects. For this reason, people have been seeking and studying a new kind of material that can greatly improve the thermal insulation reflection performance of thermal insulation materials.
In the 1990s, NASA researchers developed and used a new space adiabatic reflective porcelain layer(Therma-Cover) to solve the problem of heat transfer control of space vehicles. The material consists of tiny ceramic particles suspended in inert latex. It has high reflectivity, high emissivity, low thermal conductivity, low heat storage coefficient and other thermal properties, and has excellent thermal insulation reflection function. This high-tech material has been widely used in the space industry abroad for construction and industrial facilities, and has been exported to China for use in some large industrial facilities. But the snag is that the high price of $20 / kg of the material has made many industries in the country sigh and can not afford it. As a result, the domestic quietly set off an upsurge of research and development of new heat insulation materials, and has taken the lead in the domestic counterparts to develop a new type of space reflection insulation coating with high efficiency, thin layer, heat insulation, energy conservation, and decorative waterproofing.

The coating uses Silicon propyl emulsion and waterborne carbon emulsion with excellent heat resistance, weather resistance, corrosion resistance and waterproof properties as film forming materials, and uses extremely fine hollow ceramic particles known as space age materials as fillers. Consisting of a multi-arranged coating made of hollow ceramic grains, it reflects high solar heat in the visible and near-infrared regions of the 400-1800 nm range, and introduces an air microporous layer with a very low thermal conductivity into the coating to isolate heat energy. Transfer. In this way, by strengthening the obvious resistance to reflection of solar heat and flow transfer, it can effectively reduce radiation heat transfer and heat transfer, thereby reducing the thermal equilibrium temperature on the surface of the object, which can reduce the roof temperature by a maximum of 20 °C and the indoor temperature by 5 ~ 10 °C. The product insulation level reached R-33.3, the thermal reflectivity was 89 %, and the thermal conductivity was 0.030 W/m. K. Whether the supervision unit performs the supervision duties according to the regulations, strictly reviews the qualification certificates and professional sub-contracts of the external wall insulation professional contracting units, strictly implements the material entry acceptance and witness sampling system, and carries out inspections and side stations for the construction of external wall insulation in accordance with the requirements of the regulations.
