Почему уплотнительные кольца должны быть добавлены в водонепроницаемую распределительную коробку?

The sealing ring plays an important role in the protective function of the waterproof distribution box, and has good protection for the waterproof performance. During long-term use, the continuity of the degree of protection depends on the characteristics of the sealing ring. When the foam is accurately injected, the polyurethane seal will stay firmly in place. Due to its excellent chemical resistance and corrosion resistance, EPDM material plays a good protective role in resisting most of the widely used chemical substances. The chemical resistance of sealing ring materials varies greatly, so direct reaction of chemical composition and sealing ring is an effective method to confirm the effect as needed.

The performance of the waterproof distribution box varies according to the materials used for different sealing rings. The material and cross-sectional profile of the sealing ring determine the degree of protection of the electrical sealing box. The choice of seals is made by comparing the elasticity of the individual material components and the effects of contact with many chemicals, as well as the effects of heat and cold. It is important that the waterproof distribution box and the sealing ring have a common resistance to the same chemical substance to get good results.
