As the world's best thermal insulation material, polyurethane is widely used in various fields for its excellent performance such as environmental protection and light weight, and in recent years, it has been used more and more in the cold chain industry.
Polyurethane composite panels are also called PU sandwich panels.
The composite panel with polyurethane as the core material is composed of the upper and lower layers of color steel plate and the intermediate foamed polyurethane, which adopts the world's most advanced six-component online automatic operation mixing and pouring technology, which can complete the proportioning and mixing process of the social batching center or factory online at one time, and can be adjusted at will according to the temperature online, so as to produce a unique high-strength, energy-saving, green and environmentally friendly building board.
Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile homes, exhibition halls, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, hospitals, strata and high-rise office buildings and other fields.
It is generally used for the roof outer layer board of the building, which has good thermal insulation, heat insulation and sound insulation effects, and polyurethane does not support combustion, in line with fire safety. The joint action of the upper and lower plates and polyurethane has high strength and rigidity, and the lower plate is smooth and flat, with clear lines, which increases the interior aesthetics and flatness. It is easy to install, short in construction period and beautiful, and is a new type of building material.
The sandwich panel has light weight, beautiful and good anti-corrosion performance, and can be directly processed, it provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc., and has played a good effect of replacing wood with steel, efficient construction, energy saving, and pollution prevention.
1. Advantages of roof panels
The polyurethane roofing panels are connected by concealed nails, and the board surface is tightly overlapped. The unique waterproof groove design effectively prevents rainwater from penetrating and avoids the phenomenon of cold bridges. The peak height of 40mm greatly improves the bearing capacity of the roof panel. While ensuring the thermal insulation effect of the building, it can effectively reduce the construction cost of the customer, and the roof slope can reach as low as 3%.
2. Advantages of polyurethane composite board wall panels
Concealed nail connection, no exposed screws on the surface, beautiful and smooth building wall. Extremely high flexural capacity, superior mechanical properties of wall mechanics, reducing dependence on auxiliary steel structures. Excellent thermal insulation performance, reducing the cost of indoor air conditioning in the building. A variety of appearance effects, beautiful wall.
