The commonly used polyurethane sandwich panels in the market are divided into: Polyurethane roof panel and polyurethane cold storage version of polyurethane wall panel according to their uses.
1、 Polyurethane roof panel: it is applicable to industrial and commercial buildings with a roof inclination of 3%. The polyurethane roof panel is connected with concealed nails, and the plate surface is closely overlapped. The unique waterproof trough design effectively prevents rainwater infiltration and cold bridge phenomenon. The 40mm wave crest height greatly improves the bearing capacity of the roof slab. While ensuring the thermal insulation effect of the building, it can effectively reduce the construction cost of customers, and the roof slope can be as low as 3%. There are no exposed screws on the surface, and the building wall is beautiful and smooth. Extremely high bending capacity, excellent mechanical performance of the wall, reducing the dependence on auxiliary steel structures. Excellent thermal insulation performance, reducing the cost of indoor air conditioning equipment in buildings. A variety of appearance effects, beautiful wall.
2、 Polyurethane cold storage panels are divided into the following three types:
1. Fresh storage (the temperature of the fresh storage shall be kept at 0 ℃, and the better thickness of the cold storage plate shall be 10cm)
The fresh-keeping warehouse keeps the original quality and freshness of some agricultural products to a greater extent, that is, fresh agricultural products, after a period of fresh storage, are still in the fresh state and quality when they are just picked or close to being picked.
2. Cold storage (the temperature of the cold storage shall be kept at - 18 ℃, and the suitable thickness of the cold storage plate shall be 15 cm)
Cold storage 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 freezer shall be kept at - 38 ℃, and the suitable thickness of the freezer Board shall be 20cm)
Cold storage cold storage is mainly used for the freezing processing and refrigeration of food, drugs and machinery. It keeps a certain low temperature in the room through artificial refrigeration.
3、 Polyurethane wall panel: it is generally used for the roof outer panel of buildings. This panel has good thermal insulation, heat insulation and sound insulation effects, and polyurethane does not support combustion, meeting the fire safety requirements. The combination of upper and lower plates and polyurethane has high strength and rigidity. The lower plate is smooth and flat, with clear lines, which increases the indoor aesthetics and flatness. It is a new building material with convenient installation, short construction period and beautiful appearance.
Polyurethane sandwich panel is also known as anti leakage sandwich roof panel, polyurethane rigid foam insulation panel, polyurethane composite panel and Pu panel. It is a bimetallic, single metal and non-metal composite plate with polyurethane rigid foam as the insulation layer. It is a kind of high-efficiency and energy-saving building envelope material with wide uses and great potential. It is also a new energy-saving plate advocated and promoted by the Ministry of construction of the people's Republic of China. It can be applied to various building needs: Generally speaking, polyurethane sandwich plate can be applied to almost all kinds of building needs, including industrial plants Public buildings, composite houses, purification projects and other construction fields.
