In the construction process of spraying polyurethane high-pressure machine, the external wall thermal insulation materials have certain requirements on the climate. The climate conditions are too high, resulting in the construction water evaporation is too high, can not store appropriate moisture, will occur in the dry season, after the construction is completed, the external wall cracks, not only to achieve the insulation effect, polyurethane spraying machine generally how much money_ Brand polyurethane spraying machine how much money, and because of the external wall cracking will also cause certain damage. External thermal insulation is a widely applicable and high-tech building thermal insulation energy-saving technology.

What is the heat preservation effect of spray polyurethane high pressure machine cold storage?

Compared with the internal insulation, the external insulation technology is reasonable and has obvious advantages:

1. As the thermal insulation layer is set outside the building envelope, the external thermal insulation materials play a protective role on the main structure. The outdoor climate conditions lead to large temperature changes inside the wall, and the stress caused by the structural change caused by the temperature change occurs in the external insulation layer, which avoids the large temperature change of the internal main structure and effectively improves the resistance of the main structure Durability, prolong the life of the building.

2. The application of external thermal insulation is beneficial to eliminate or weaken the influence of thermal bridge, external wall ring beam, structural column, frame beam, roof retaining wall and roof panel at the junction of internal and external walls.

3. The main structure in the indoor side, because of it's strong heat storage capacity, is conducive to indoor thermal stability, avoid large temperature difference at room temperature, and improve the humidity of the wall.

4. When the building uses external insulation for reconstruction construction, it can reduce the interference to the residents. In the decoration, the internal insulation layer is easy to be damaged, and the external insulation can avoid the damage of the insulation layer.
