Briefly Describe The Characteristics And Principles Of Polyurethane Spraying Machine
Polyurethane spraying machine is also called high-pressure polyurethane spraying machine. Its working principle is that when it is used in high-pressure spraying machine spraying, the polyurethane will perform high-speed impact and violent rotation in a mixed room with a small space, and then it will be very mixed. full. The high-speed movement will cause the material to form a fine mist droplet shape at the nozzle of the spray gun, and then it will be sprayed evenly on the surface of the object.
Polyurethane spraying machine has many characteristics, for example, for various shapes of substrates, whether the substrate is flat, vertical or top, or round and spherical, or other complex irregular shapes All of the substrates can be sprayed and foamed, so there is no need to make too expensive molds. The shape of the foam insulation layer after spraying and foaming is the same as the shape of the substrate, and no seams are visible. , The heat insulation effect is very good, which greatly improves the production efficiency. It is especially suitable for the isolation of large-area special-shaped objects. The molding speed is also very fast. The polyurethane spraying machine has very good urethane adhesion Strong, it can be used in concrete and masonry, wood and steel, asphalt and rubber, etc., to bond all their surfaces firmly. The polyurethane sprayed by the polyurethane sprayer has a strong sealing performance, and no joints can be seen at all. The outer envelope of the building completely wraps the main body, effectively preventing wind and moisture from flowing in and out of the building through the joints and gaps, and achieves a completely sealed state.
