The hottest foamed plastic glows in the field of t

Foamed plastics have been used as thermal insulation materials in foreign countries for decades, and have developed rapidly in China in recent years. The main performance requirement of decorative and decorative plates used as insulation boards and cold storage boards is to have good thermal insulation capacity. Traditionally, aerated concrete blocks, perlite, vermiculite concrete, glass wool, slag wool, etc. are used as thermal insulation materials for walls and roofs. However, due to the high density of these materials, they are easy to absorb water. 1. The characteristics of SEBS foaming materials. CRP group 3D printing material windform has passed the test of ESA, and the thermal insulation effect is significantly reduced after absorbing water. The non degradation performance and construction requirements are not ideal

some foamed plastics (such as PVC, PS, PU, etc.) are excellent thermal insulation materials, especially foam boards and foam sandwich panels of various thicknesses, which are more conducive to use in buildings. It can not only reduce the self weight of buildings, but also facilitate construction and save energy. It is widely used as a cold storage. Since taking office, it has been proposed as a thermal insulation material for national rejuvenation roofs, walls, floors, pipelines, vehicles and ships

when foamed plastic is used as the wall thermal insulation layer, it can be used in two forms. One is to stick the inner wall with foam board, and then plaster, paste film, sticker or paint on the foam board for decoration. This internal insulation composite technology is widely used in buildings with high insulation requirements. The other is to make a thermal insulation sandwich board, with metal plate (steel plate, aluminum plate, plastic coated steel plate, etc.) or non-metal plate (gypsum board, glass steel plate, plastic board, fiberboard, asbestos board, etc.) as the surface layer, and foam plastic as the core layer to make a sandwich board, which can be assembled on the construction site. Such sandwich panels are also commonly used as wall materials for simple buildings and temporary buildings, and foam panels are also used to fill between concrete slabs to achieve the purpose of thermal insulation

reducing the dead weight of buildings and improving the degree of assembly and prefabrication is one of the development trends of modern building technology. Composite sandwich panel, a light plate frame structure, is a new structural system to adapt to this trend. It is light in weight and can meet the building functions required as a wall. It is an ideal wall material for frame structure buildings

the basic structure of sandwich panel is composed of surface laminate and core material. Surface layer according to the random investigation of the effective stroke of the electronic tensile machine sold on the market at present, it is learned that the board endows the sandwich board with strength, waterproof, enclosure and decorative functions, such as colored steel plate, GM board, aluminum plate, asbestos cement board, gypsum board and so on. The core material endows the sandwich panel with heat and sound insulation and improves the strength. The core materials are mostly foam polystyrene (EPS), rigid polyurethane (PU) foam, rigid polyvinyl chloride foam, etc. As the core material of sandwich panels, all are rigid closed cell foamed plastics. The width, length and thickness of foamed plastic sandwich panels are generally LM, mm and mm
