At present, energy conservation and environmental protection has become the theme of development, many large domestic electric door and door enterprises are from the source of materials to the series of mechanical processing to make a fuss to save resources to achieve sustainable development. P>
According to Jin Hongxing electric door responsible person projections, China's urban and rural construction houses each year to more than 20% growth rate, which both building 40 billion square meters, more than 95% for high energy consumption buildings, the electric door energy consumption for the developed countries 2 Times to 3 times. In the next 30 years, China will build 40 billion square meters of new buildings, therefore, plastic steel electric door industry will usher in an unprecedented opportunity for development.
Characteristics of decomposition: In terms of heat transfer, steel-plastic electric door materials are hot bad conductor, the thermal conductivity is only steel 1/360, aluminum 1/250, with good thermal insulation performance; in airtight performance, Plastic steel door frame or fan material is through the melting of the welding, the box, the fan is a whole, there is no gap between the vertical material, put an end to the air through the transverse material and the vertical material of the possibility of splicing the corner; Installation, between the wall and the box between the use of flexible support, with styrofoam for sealing.
