Polystyrene granule insulation slurry external wall insulation process waste polystyrene plastic processing into 0.5 mm ~ 4 mm particles, as a light aggregate to prepare insulation mortar. The technology includes insulation layer, crack-resistant protective layer and anti-seepage protective surface layer. ZL rubber powder polyphenyl granule insulation material and technology were listed as national-level construction method by the Ministry of Construction in 1998, and it is currently widely recognized as external wall insulation technology. .

The construction technology is simple, the labor intensity is reduced, the work efficiency is improved, the work quality is not affected by the structural quality difference, the wall surface is not required to be repaired and leveled when the defective wall is constructed, and the use condition of the external wall thermal insulation project is solved. The interface layer is easy to debond and empty, and the surface layer is easy to crack. Compared with other external insulation, the building construction cost can be reduced when the same insulation effect is achieved. Compared with the polystyrene board outer insulation wall, it can be reduced by about 25 yuan per square meter.

In the energy-saving insulation wall technology, the wall is also made into a sandwich layer, and perlite, wood chips, mineral wool, glass wool, polystyrene foam, polyurethane foam, etc. are filled into the interlayer to form an insulation layer.

Prospects for the development of metal exterior wall insulation panels Because the superiority of exterior wall insulation is increasingly recognized and accepted by all parties, China's exterior insulation projects are rapidly increasing, and the energy-saving renovation of existing buildings is gradually put on the agenda. External thermal insulation of the external wall must be a basic measure for building energy-saving renovation. As the future exterior insulation technology will be more diverse, rich and colorful, using different insulation materials, different structures, different processes coexist, and the Chinese economy is in a period of vigorous development, the scale of construction is large, so our country's external walls The external insulation market is likely to become the world's largest and most dynamic external insulation market.
