Polyurethane rigid foam sandwich wall hanging board is a key product in the fashionable new wall insulation system of foreign countries and Taiwan, and it is a new type of exterior wall with heat insulation, heat insulation, moisture proof, fire prevention and decoration functions. Building materials.
The outer wall hanging plate is hung on the outer wall surface of the building through the keel. The plate and the plate are connected by a wedge groove, which is impervious to water and light in weight. An air heat insulation layer is formed between the keel and the wall, and the wall is satisfied. Body breathing. The front side of the external wall hanging board is a colored aluminum plate or steel plate which is painted and anodized, and the surface can be pressed with various patterns as needed, and the appearance is beautiful.
The outer wall hanging board is generally 500mm in width and 25mm in thickness, and is composed of an outer layer, a core portion and an inner layer material. The outer layer material usually adopts embossed and coated aluminum plate (generally 0.5mm thick) or steel plate (generally 0.37mm thick), the core material is polyurethane rigid foam (general thickness is 25mm), inner layer material Aluminum foil (typically 0.06 mm thick) or paper is usually used.
Due to the continuous industrial production, convenient installation and low maintenance cost, the performance and price ratio of the external wall hanging board insulation system is superior.
Brief introduction of continuous production line of polyurethane rigid foam sandwich wall hanging board:
Polyurethane rigid foam sandwich wall hanging board continuous production line is used to produce outer wall hanging plate with upper layer of aluminum plate or steel plate, intermediate interlayer of polyurethane rigid foam, lower layer of aluminum foil or paper, hanging plate thickness 25mm, width 350~ 500mm, length is custom.
The working principle is as follows: the PU raw liquid is fed into the mixing head by a certain ratio, mixed and evenly poured on the inner layer of the hanging board, and simultaneously fed into the double crawler type laminating conveyor and the upper layer of the hanging board material. And the lower chain plate is foamed and solidified. The hanging board is cut into the specified length by the automatic tracking and cutting machine on the production line, and the production capacity is 3-8 m/min.
