Supply of polyurethane foaming machine in Hebei Province. Polyurethane spraying machine. Polyurethane foaming for exterior wall insulation is a new building energy-saving technology. After being used in engineering examples, although there are still many areas for improvement, the advantages of this technology are The advantages are obvious. , good thermal insulation effect
Urethane foam is a high-density thermosetting polymer and an excellent thermal insulation material. Its thermal conductivity is.~./(?), permanent mechanical anchoring, temporary Fixing, wall-penetrating pipes, or attachments on exterior walls often cause local thermal bridges. However, the polyurethane spraying process is adopted. Since the rigid foam sprayed polyurethane has a high bonding strength with general wall materials, no adhesive or anchoring is required. It is a natural adhesive material that can form a continuous insulation layer, ensuring the interaction between the insulation material and the wall and effectively blocking thermal bridges.
, strong stability
Polyurethane foam is firmly combined with the base wall, which is the basic prerequisite to ensure the stability of the external insulation layer. For the wall, the surface should be treated with interface treatment. If the surface layer is loose or hollow, it must be carefully cleaned to ensure that the rigid foam polyurethane spray insulation layer is closely combined with the wall. The rigid foam polyurethane spray exterior insulation system should be able to withstand the combined effects of the following factors, that is, under the most unfavorable local temperature and humidity conditions, it can withstand various combined internal and external loads such as wind, dead weight, and normal collisions, and the insulation layer still cannot The base layer separates, peels off and remains stable when wet.
, has good fireproof performance
The polyurethane foam insulation layer is located on the outside of the exterior wall, and fireproof treatment cannot be ignored. After adding flame retardant, polyurethane is a flame-retardant and self-extinguishing material. It is compounded with rubber powder polystyrene particle slurry to form a fire prevention system, which can effectively prevent the spread of fire. The wall surfaces and sides of doors and windows of the building are all tightly covered with fireproof rubber powder polystyrene granules, and no exposed parts are allowed. The use of thick rubber powder polystyrene granules waterproof plastering surface layer is conducive to improving the fire resistance of the insulation layer. .
