Analysis of the development status of SMC sheet

SMC sheet, SMC is a composite material, belongs to a kind of glass reinforced plastic. The main raw material consists of GF (special yarn), MD (filler) and various auxiliaries.

The development status of SMC sheet and the molding process, the selection of molding materials to a certain extent determines the quality of sheet molding plastics (SMC) products, the selection of appropriate raw materials can meet the special performance requirements of products, and the molding process is also the top priority in the manufacturing of molding parts. First of all, SMC raw material composition, including resins, initiators, low shrinkage additives, chemical thickeners, internal release agents, colorants and reinforcing materials, the performance requirements of each component is also briefly introduced; Secondly, the forming process of SMC is discussed in layers, including the type and structure of the production unit, the production process of SMC, the molding equipment and process of SMC, and for the problems of SMC products, this paper draws on several foreign improvement measures, including surface paint bubble, solvent inhalation, high density, environmental pollution and the improvement of the auto parts production line, etc.

The above is a brief discussion on the industrial application and recycling of SMC. I hope you can have a new understanding of SMC composite material through this paper. SMC material has very excellent performance characteristics. In practical application, this material is often used as a common part, with good sealing and waterproof performance, corrosion resistance, electric theft resistance, electrical insulation, beautiful appearance, plus the safety protection of lock and lead seal, and long service life. In addition, SMC material also has mechanical properties, thermal stability, chemical corrosion resistance and other excellent properties.
