At present, the raw materials for producing standard waterproof junction boxes in the world mainly include: ABS engineering plastics, polycarbonate (PC), PC/ABS, glass fiber reinforced polyester, and stainless steel. Depending on the site environment, the user can select materials that meet the requirements for field use.
Glue-type waterproof junction box ABS engineering plastic: Acrylonitrile-Butadiene-Styrene (ABS) is a general-purpose thermoplastic polymer, ABS performance characteristics: good rigidity, high impact strength Heat resistance, low temperature resistance, chemical resistance, mechanical strength and electrical properties are excellent, easy to process, dimensional stability and surface gloss are good, easy to apply, color, and can also be sprayed metal, electroplated, welded and bonded. Secondary processing performance. Because the characteristics of ABS combines the characteristics of its three components, it has excellent comprehensive performance and becomes one of the preferred plastics for electrical components, home appliances, computers and instrumentation.
Polycarbonate (PC) material: Polycarbonate (PC) is a polymer containing a carbonate group in the molecular chain. It can be classified into aliphatic, aromatic, aliphatic-aromatic, etc. depending on the structure of the ester group. Types. Among them, the aliphatic and aliphatic-aromatic polycarbonates have low mechanical properties, which limits their application in engineering plastics. At present, only aromatic polycarbonate has been industrially produced. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five engineering plastics.
PC/ABS material: polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture, thermoplastic plastic made of polycarbonate (Polycarbonate) and polypropylene (ABS) alloy, combining two kinds Excellent properties of materials, moldability of ABS materials, mechanical properties of PC, impact strength, temperature resistance, UV resistance, etc., can be widely used in automotive interior parts, business machines, communication equipment, home appliances and lighting equipment. .
It can be used together with temperature controller to form infrared radiant heating system. According to the temperature needs of the user, the temperature in each room can be freely adjusted. When the indoor temperature reaches the preset temperature, the heating system will automatically stop and the heat accumulator begins to emit heat so as to maintain the preset temperature for a long time, saving energy and power.
