Generally speaking, polyurethane sandwich panels can be applied to almost all kinds of different building needs, including industrial plants, public buildings, composite houses, purification projects and other building fields.
Public buildings
Polyurethane sandwich panels can be mainly applied to the roofs and exterior walls of public buildings with large space needs, such as: mechanisms, waiting or waiting halls of stations, stadiums, theaters and auditoriums, exhibition halls and convention centers, museums, etc. Public buildings have a series of characteristics that require more space, indoor air conditioning, fire prevention and so on than industrial plants. Most of these buildings adopt the roof truss structure form of grid or pipe truss. Therefore, higher requirements are put forward for the materials of roof panels in terms of light weight, thermal insulation and insulation, fire safety, waterproof, sound absorption, durability and so on.
Industrial plant and warehouse
Polyurethane sandwich panels are mainly used for roofs and exterior walls of industrial plants and warehouses. In the past, prefabricated concrete slabs or asbestos slabs were used for the roofs of industrial plants. With the rapid promotion of light steel structure, polyurethane sandwich panel has replaced the above two materials with its many significant advantages. At the same time of providing better heat insulation effect, the sandwich panel, together with the mature and developed light steel structure, can truly reflect a series of advantages of the light steel system, such as light weight, fast and efficient, flexible layout, etc., so it has become the preferred scheme in single-storey factory buildings. For multi-storey industrial plants, in addition to sandwich panels for the roof, polyurethane sandwich panels can also be used for flexible arrangement for the exterior walls to beautify the building appearance through the changeable colors and shapes of color coated panels. For industrial buildings with constant temperature and humidity requirements, the use of sandwich panels with better thermal performance than brick walls as enclosure materials can greatly save operating costs after completion.
Purification engineering
With the continuous progress of society, electronics, medicine and other industries have developed rapidly. In the process of product manufacturing in these industries, it is necessary to provide a high cleanliness production environment. Color coated sandwich panels are widely used in production and working environments with cleanliness requirements as inner wall and ceiling materials because the color coated panels on their surfaces are not easy to attach dust, easy to clean and have fewer joints. The application range includes electronics and computer product manufacturing, medical supplies and drug production, aerospace, precision instrument manufacturing, food production, medical operating room and other industries. Although the cleanliness requirements of some plants are not high, polyurethane sandwich panels are also widely used as the internal partitions of plants in view of the flexible disassembly and assembly of sandwich panels.
Composite house
Composite houses built with polyurethane sandwich panels have been widely used, with a series of advantages such as light overall weight, flexible combination, convenient and fast construction, no need for secondary decoration, and easy disassembly and relocation. Sandwich panels are widely used to build additional storey houses. Due to the shortage of urban land, many units and individuals hope to build an additional storey house on the roof without causing a large load on the original building. In this way, the use area is expanded and the heat insulation and waterproof problems of the original roof are solved. The advantages of sandwich panel composite houses just fully meet the needs of users. Sandwich panel composite house can be moved many times, which also makes it widely used in temporary buildings. In addition, sandwich panels are also widely used in industrial plants as composite houses for various purposes.
Because of the particularity of polyurethane sandwich panel, in addition to being widely used in the above-mentioned building fields, people also give full play to its characteristics and apply it to wider fields, such as the internal partition wall of ships, cold storage, sound insulation wall of highways, etc. with the continuous progress of science and technology and the renewal of people's work and life needs, so as to better meet people's needs, Create a broader space in the building materials industry where new products emerge one after another.
