Solve the poor insulation of wooden, steel and plastic meter boxes that are easy to age and corrode

SMC composite material is the abbreviation of Sheet molding compound, that is, sheet molding compound. The main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additive, MD (filler) and various auxiliary agents. It first appeared in Europe in the early 1960s, and around 1965, the United States and Japan successively developed this craft. In the late 1980s, our country introduced foreign advanced SMC production lines and production techniques.

Features: The unique performance of SMC composite materials solves the shortcomings of wooden, steel and plastic meter boxes that are easy to age, corrode, poor insulation, poor cold resistance, poor flame retardancy, and short life. The excellent performance of composite meter boxes, some sealing Waterproof performance, anti-corrosion performance, anti-stealing performance, never need grounding wire, beautiful appearance, safety protection with lock and lead seal, long service life, composite cable bracket, cable trench bracket, composite meter box, etc. are widely used in agricultural Used in network and urban network reconstruction.

Application: The application of SMC composite materials in explosion-proof electrical equipment casing products has changed the situation that the original explosion-proof electrical equipment casing products are mainly made of steel and aluminum. The application of SMC materials overcomes the heavy steel and aluminum casings of explosion-proof electrical equipment. Easy to generate sparks. The application of SMC materials in explosion-proof electrical appliances in my country is in its infancy, and the shells of explosion-proof electrical equipment are still mainly made of metal shells. SMC materials have the advantages of superior corrosion resistance, light weight, easy engineering design, and flexibility. , good thermal stability, high strength, corrosion resistance, long service life, high production efficiency and a series of advantages, these performance advantages make SMC composite materials suitable for application in explosion-proof electrical equipment shell products.

Shandong Xinming FRP Products Co., Ltd. and the Fourth Design and Research Institute of the General Staff of the Chinese People's Liberation Army jointly developed a series of light-weight protective airtight doors for civil air defense protection projects. They have reached the domestic level after being evaluated by experts, filling the current gap in domestic SMC products. Revolutionary changes in the civil air defense engineering protective equipment industry. The lightweight protective airtight door is made of SMC composite material and produced by molding process. The built-in embedded insert is made of SMC under high temperature and high pressure, and its strength is greatly increased. The door and the door frame are sealed with sealing strips, and the airtight measures are reliable.
