The new foam board is an important core of China''s building insulation materials. New foam board materials are constantly emerging. From the perspective of the materials and varieties of building insulation materials, the development of new insulation board technology is relatively extensive at home and abroad for insulation materials based on polystyrene.
The amorphous slurry insulation material can overcome these shortcomings of the sheet metal, so it constitutes an important part of the building insulation material. Developed countries such as Europe and the United States started early in the research and application of slurry insulation materials, and the technology is relatively mature, and has been effective in research and application. The Refrigerator Express reporter learned that the developed countries are mainly based on lightweight multi-functional composite slurry insulation materials in the research and development of slurry insulation materials. The performance of such slurry insulation materials is significantly improved compared with traditional slurry insulation materials, such as low thermal conductivity and good safety and durability. At the same time, this kind of composite slurry insulation material has excellent functionality, such as non-French flame retardant polyurethane foam composite slurry insulation material, ultra-lightweight full-water calcium silicate slurry insulation material, etc., which can meet different uses. Conditional requirements.
According to experts in the air-conditioning and refrigeration market, although polystyrene board has good thermal insulation effect as a thermal insulation material, due to the characteristics of the plate, the polystyrene board is mainly fixed at the point of connection with the main body during construction. Auxiliary, the necessary splicing and bonding between the plates should not be carried out, and the construction process is complicated and the overall cost is high. At the same time, the insulation of the outer protective structure is not suitable due to the hydrophobicity of the polystyrene board and the conventional hydrophilic material. The foam board causes the subsequent construction quality outside the surface layer to be difficult to ensure, and the surface mortar is prone to cracking, falling off, hollowing, etc. The quality problem poses a great constraint on the exterior decoration of the building such as the use of tiles or paints. Foreign countries attach great importance to environmental protection issues in the insulation materials industry, and actively develop green insulation materials products, from raw material preparation (mining or transportation), product production and use, and future disposal issues, striving to maximize resources and reduce environmental impact.
