Now in the civil construction market, rock wool, cement foam board and other high energy consumption, poor insulation products occupy a large number of the market. After the introduction of 35, polystyrene recycling in China. Many well-known real estate developers, including some municipal projects have adopted the XPS as the preferred material for external wall insulation because the polystyrene resin is xps raw material in China.
With the rapid economic development, increasing energy consumption, energy-saving emission reduction is included in the national "second five" development program, building energy conservation as an important part of energy conservation. At present, the main form of building energy saving is the wall insulation, including external wall insulation system, external wall insulation system.
In recent years, the national "energy-saving emission reduction" policy has led to the rapid promotion of organic external wall insulation technology, on the one hand, building energy efficiency significantly improved, and on the other hand with supporting fire safety regulations are lagging behind, external wall insulation system market has just started, the standard is not perfect, the market competition is also increasingly fierce, so there is still the quality of insulation materials is not high, the product is not complete, the Ministry of perfect and other issues. In terms of insulation materials, the external wall insulation system durability and fire resistance is the external wall insulation technology to solve the two major problems.
On the other hand, one of the important reasons for the slow development of new wall materials in the development of new building walls in China is the lack of restrictions on solid clay bricks, the lack of concrete measures to protect land resources and the production of clay at the expense of land Brick cost is very low, so that any kind of new wall materials in the price can not compete with. Second, the new wall materials, scientific and technological content is good, often higher than the current price of the general use of the material, the role of restricting the market.
