The formation of polyurethane foam needs to go through two stages of foaming and curing. From the beginning of the mixing of the black and white materials to the stop of the foam volume expansion, this process is called foaming. During the foaming process, the system releases a large amount of reaction heat. The rigid foam polyurethane (PU) insulation material is a polymer with repeating structural units of urethane segments made by the reaction of isocyanate and polyol. Because of its good thermal insulation performance and excellent waterproof performance, it is widely used in external wall thermal insulation, roof thermal insulation, cold storage, grain storage, archives, pipes, doors and windows and other special parts of insulation. Polyurethane foaming equipment is used in roof and wall insulation by Dali abroad. The main application forms are composite board villages and on-site spraying. High pressure spray, strong penetration force, make the paint penetrate into the wall gap, increase the mechanical bite force between the coating and the wall, improve the paint adhesion, extend the coating life, the coating is denser, the adhesion is improved, and the spraying ability is higher. The viscosity of the coating does not need to add water excessively, so the physical properties of the coating can be maintained intact, and the life of the coating can be effectively extended.
The waterproof performance of rigid polyurethane foam, continuous jointless characteristics and no adhesive process ensure the better wind pressure resistance of the cavity-free wall, and block the anti-alkali pathway of the wall caused by the capillary tube. Existing board thin paste system and polystyrene particle slurry system must strictly prevent the moisture hazards caused by the cracks on the cover. The polyurethane foaming machine can use the traditional cement mortar surface layer and other surface materials, which will not cause heat preservation. The thermal insulation performance decline caused by material moisture and the hidden danger of adhesive moisture.
