Several common classifications of polyurethane sheets. The polyurethane board can be divided into: polyurethane roof panel, polyurethane wall panel, and polyurethane cold storage board according to the use. Today, Dalton will give you a detailed analysis of several common classifications of polyurethane boards.
Polyurethane roof panel: It is applicable to industrial and commercial buildings with a roof inclination of 3%. The self-cleaning * * panel reduces the amount of dust on the roof, keeps the building roof crystal for a long time, and high wave peaks improve the bearing capacity of the roof panel. It has the characteristics of large span, fast drainage, convenient installation, etc. The lap joint is designed with fluid mechanics to ensure fast installation, air tightness, and good capillary water seepage prevention effect.
Polyurethane wall panel: It is generally used for the outer roof panel of buildings. The panel has good heat insulation, heat insulation and sound insulation effects, and the polyurethane does not support combustion, which conforms to fire safety. The combination of upper and lower boards and polyurethane has high strength and stiffness. The lower board is smooth and smooth, with clear lines, which increases the indoor beauty and flatness. It is a new type of building material with convenient installation, short construction period and beautiful appearance.
Polyurethane cold storage plates are divided into the following three types:
1. Fresh storage (the temperature of the fresh storage is kept at 0 ℃, and the preferred thickness of the cold storage plate is 10 cm)
The fresh-keeping warehouse * largely maintains the original quality and freshness of some agricultural products, that is, fresh agricultural products. After fresh-keeping and storage for a period of time, they are still fresh or close to the fresh state and quality when they are just picked.
2. Cold storage (the temperature of the cold storage is kept at - 18 ℃, and the appropriate thickness of the cold storage plate is 15cm)
The refrigerated warehouse is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, drugs, chemical raw materials, electronic instruments, etc.
3. Freezer (the temperature of the refrigerator shall be kept at - 38 ℃, and the appropriate thickness of the refrigerator plate shall be 20 cm)
The cold storage is mainly used for the freezing processing and refrigeration of food, medicine and machinery. It can keep a certain low temperature indoors through manual refrigeration.
The above are the common classifications of polyurethane boards analyzed by Xiao Bian. With the implementation of the national energy conservation policy and the deepening of energy conservation, the polyurethane board rigid foam insulation composite board has high strength due to its * * energy-saving characteristics, high cost performance, green environmental protection and other characteristics, as well as its thermal insulation and ideal bending resistance. The surface is flat. The board type is fashionable. Especially in thermal insulation and fire protection, it has won the recognition of the market and is welcomed by users.
