The waterproof junction box is also called the electrical sealed box, which can be roughly divided into two types: special type and general type. Its raw materials mainly include the following five types: ABS engineering plastics, polycarbonate (PC), PC/ABS, glass fiber reinforced polyester, and stainless steel. What is the difference between various materials of waterproof junction box, and what kind of performance do they have?
1) ABS engineering plastic: It is hard to be damaged by impact, can withstand low temperature and heat, is not easy to be corroded by chemicals, is simple to process and can be colored, sprayed metal, electroplating, welding, etc., so it becomes electrical components, household appliances, A preferred material for computers, instruments and instruments.
2) Polycarbonate (PC) material: It has strong adaptability to temperature, UV resistance and high mechanical properties, that is, good impact resistance, so it has become the fastest-growing general engineering plastic.
3) PC/ABS material: Combine ABS and PC together, take advantage of the easy processing characteristics of ABS material and the good strength of PC, strong impact resistance, can withstand low temperature and extreme heat, and anti-ultraviolet properties, so it The range of use is relatively wide and can be applied to automotive internal parts, business machines, communication equipment, household appliances and lighting equipment.
4) Glass fiber reinforced polyester material: also known as glass reinforced thermosetting plastic or glass fiber reinforced plastic. It is a composite material composed of resin (a kind of thermosetting plastic with bonding effect) and glass fiber. It has good anti-shock function and adhesion, relatively high impact strength and heat resistance, and strong resistance to mold, and the volume shrinkage during processing and molding is small.
Through the above detailed introduction, we know what kind of decoration environment this waterproof junction box of different materials is suitable for. This should help us to choose the model of waterproof junction box. For example, we are just ordinary home decoration. Choose PC/ABS waterproof junction box model, its performance is sufficient to meet our requirements and the price is not high. Of course, if it is used in a harsh environment such as a high temperature or an environment with some chemical substances, the choice of the waterproof junction box model must be cautious. Finally, we must choose a suitable waterproof junction box according to our own environmental requirements.
