Polyurethane sandwich board is mainly used in the roofing and outer wall of public buildings with large space needs, such as: airport, station waiting or waiting hall, stadium, cinema and auditorium, exhibition hall and exhibition, museum, etc.Public buildings because of the need to provide more room, indoor air conditioning, fire protection and a series of higher than industrial workshop requirements, the characteristics of such buildings with rack or pipe truss roof truss structure form, therefore in light of roof plate material, heat preservation and heat insulation, fire rating, waterproof, sound absorption, durability, etc are put forward higher requirements.
Polyurethane sandwich panels are mainly used in roofing and external walls of industrial workshops and warehouses.In the past, precast concrete slabs or asbestos slabs were used for the roofs of industrial buildings.With the rapid promotion of light steel structure, polyurethane sandwich panel has also replaced the above two materials with a number of significant advantages.In addition to providing better thermal insulation effect, sandwich panel with the mature development of light steel structure, can reflect the light steel system light, fast, high efficiency, flexible layout and a series of advantages, so in the single-storey factory building has become the first choice of scheme.For multi-storey industrial plants, in addition to the roof of the roof can use sandwich board, external wall can also use polyurethane sandwich board for flexible arrangement, through the color coated board of the variable color and shape to beautify the building appearance. For industrial buildings requiring constant temperature and humidity, the sandwich board with better thermal performance than brick wall is used as enclosure material, which can greatly save the operating cost after completion.
With the continuous progress of society, electronic and pharmaceutical industries are developing rapidly. In the process of product manufacturing in these industries, it is necessary to provide a cleaner production environment. Color coated sandwich board because of its surface of the color coated board is not easy to adhere to dust, easy to clean and joint less, so sandwich board as an interior wall and ceiling material, widely used in the production and working environment with clean requirements. Applications include electronic and computer products manufacturing, medical supplies and pharmaceutical manufacturing, rigorous instrumentation manufacturing, food production, medical operating rooms and many other industries. Although the cleanliness of some factories is not high, but in view of the characteristics of flexible disassembly of sandwich boards, polyurethane sandwich boards are also widely used as the partition wall inside the factories.
Polyurethane sandwich board due to the particularity of its material, in addition to the widely used in the construction field, people also give full play to its characteristics, applying it to a wide area, such as the ship within the partition, cold storage, highway sound barriers, etc., and along with the advance of science and technology and people work life need to upgrade, so as to better meet the needs of the people, new products emerge in an endless stream of building materials industry to create a broader space.
