In the construction process of building thermal insulation and cold insulation, many materials are used. Among them, polyurethane composite material is one of them. It has unique thermal insulation performance, high power saving efficiency, and environmental protection. It has been widely used in these aspects. Application, but there are still many precautions in the process of use. When foaming, the ratio of white material to black material should be determined in strict accordance with the instructions for use to ensure that the process performance of the system and the various basic properties of the foam are not affected.
Many families are not familiar with polyurethane composite materials. They only know that a spray insulation system will be used in the building's thermal insulation system. In fact, in many cases, this layer of thermal insulation system is polyurethane composite material. In order to ensure that the building has a sufficiently stable and reliable thermal insulation system, polyurethane composite materials are used indoors and outdoors. And the advantages of using this material are many. The polyurethane composite material of the present invention has excellent thermal insulation performance and convenient molding performance, and has extremely wide applications in heat preservation and refrigeration; and the polyurethane composite material is not easy to use, such as large-size spherical storage tanks, large-diameter special-shaped pipe fittings, cold storage walls Etc., the best method is spray foaming on site: This method includes the following steps: spraying polyurethane foam material, rapid foaming material and gel directly on the surface of the object to form an insulating and heat-insulating layer consistent with the shape of the substrate. Rigid foam plastic is a new type of polymer material that integrates waterproof and thermal insulation. Through on-site spraying, foam is formed quickly, forming a continuous tight and seamless foam. It has good heat preservation performance and waterproof performance, and realizes the integration of water heat preservation. If you think that the role of polyurethane composites is only in the insulation system, then you are wrong. Polyurethane composites can be used to make composite floors. This kind of floor is a new type of practical floor. It uses polyurethane composites as the main material.
