The rigid polyurethane foam is a closed structure with good insulation, light weight, high specific strength and convenient construction. It also has the characteristics of sound insulation, shock proof, electrical insulation, heat resistance, cold resistance and solvent resistance. It is widely used in insulation, cold storage, refrigerator car and other insulation materials of refrigerator and freezer, building, building, and so on. Storage tanks and pipes insulation materials, a small number of non adiabatic occasions, such as imitation wood, packaging materials, etc. Generally speaking, lower density polyurethane rigid foam is mainly used as thermal insulation material, and high density polyurethane rigid foam can be used as structural material (imitation wood).
Polyurethane rigid foam is generally foaming at room temperature, and the molding process is relatively simple. According to the degree of mechanization of construction, it can be divided into manual foaming and mechanical foaming, and the pressure can be divided into high pressure foaming and low pressure foaming according to the pressure of foaming, and can be divided into pouring foam and spray foaming according to the molding method.
The main uses of this section are 1 of the following aspects: frozen and refrigerated equipment in food industries, such as refrigerators, freezers, refrigerators, refrigerated cars and so on. The polyurethane foam is the most ideal insulation material for freezing and refrigerating equipment.
2, thermal insulation of industrial equipment, such as storage tanks, pipes and so on.
3, building materials: in developed countries in Europe and America, building polyurethane hard bubbles account for about half of the total consumption of hard bubbles, more than double the amount of hard bubbles such as refrigerators and freezers. In China, the application of hard bubbles in the construction industry is not as common as that of western developed countries, so the potential of development is very large.
4, transportation industry: automobile roof, interior decoration, etc.
5, imitation wood: high density (density 300~700kg/m3) polyurethane rigid foam or glass fiber reinforced hard foam is structural foam plastic, also known as imitation wood, with high strength, good toughness, compact and tough crust, simple molding process, high production efficiency, strength can be higher than natural wood, density can be lower than natural wood, can be replaced. Wood is used for all kinds of high-grade products.
6, sealing materials, and so on.
