Polystyrene particle thermal insulation slurry for external wall thermal insulation process and crushes waste polystyrene plastic (referred to as EPS) into particles of 0.5 mm to 4 mm, which are used as light aggregates to prepare thermal insulation mortar. The technology includes thermal insulation layer, anti-cracking protective layer and impermeable protective surface layer (or surface layer anti-seepage and anti-cracking two-in-one mortar layer). Among them, ZL rubber powder polystyrene particle thermal insulation material and technology is currently widely recognized external wall thermal insulation technology.

The construction technology is simple, reduces labor intensity and improves work efficiency; it is not affected by differences in structural quality, and does not need to be repaired and leveled when there is a wall construction, and at the same time solves the problem of interface caused by poor use conditions in external wall insulation projects. The layer is easy to debond and hollow, and the surface layer is easy to crack. Compared with other external thermal insulation, under the condition of achieving the same thermal insulation effect, the construction cost of the house can be reduced. For example, compared with the polystyrene board external thermal insulation wall, it can be reduced by about 25 yuan per square meter.

In addition, in the energy-saving thermal insulation wall technology, the wall is made into an interlayer, and perlite, wood chips, mineral wool, glass wool, polystyrene foam, polyurethane foam (can also be foamed on site) are filled into the interlayer. , forming an insulating layer.

Prospects for the development of metal external wall thermal insulation decorative panels As the advantages of external wall thermal insulation are more and more recognized and accepted by all aspects, the external wall thermal insulation projects in my country are increasing rapidly, and the energy-saving renovation of existing buildings is gradually put on the agenda , the external insulation of external walls must be a basic measure for building energy-saving renovation. As the future external wall thermal insulation technology will be more diverse and colorful, the use of different thermal insulation materials, different structures, and different techniques (handmade, semi-industrialized, industrialized) coexist, and China's economy is booming. During the period, the building scale was huge, therefore, my country's external wall thermal insulation market may become the world's largest external thermal insulation market.
