Corrugated tube for automobiles
The excellent performance of Hangzhou Shunhao Rubber Engineering Co., Ltd. has received much attention and appreciation from the industry. High temperature resistance, corrosion resistance, wear resistance, easy construction, energy saving, and reliability. It can withstand the most demanding environment and is part of the excellent performance of Hangzhou Shunhao products. It has become the drafting and writing unit of the national standard "rubber lining", "construction specifications for industrial equipment and pipeline anti-corrosion engineering", "flue gas desulfurization lining" and "corrosion protection training course", and obtained the first-class qualification for anti-corrosion construction.
Bellows primarily utilize the unique properties of rubber. Such as high elasticity, high air tightness, medium resistance and weather resistance and radiation resistance. It is made of high-strength, cold-heat-stabilized polyester cord obliquely cross-checked and then cross-linked by high pressure and high temperature molding. The internal density is high, it can withstand high pressure, and the elastic deformation effect is excellent.
Types and uses of commonly used materials: Sealing ring materials should meet the sealing function requirements. Due to the different media being sealed and the different working conditions of the device, the sealing material is required to have different adaptability.
The requirements for sealing materials are generally:
1) The material has good compactness and is not easy to leak media;
2) have appropriate mechanical strength and hardness;
3) good compressibility and resilience, and small permanent deformation;
4) It does not soften under high temperature, does not decompose, does not harden at low temperature, and does not crack;
5) Good anti-corrosion performance, long-term work in acid, alkali, oil and other media, its volume and hardness change is small, and it does not adhere to the metal surface;
6) The friction coefficient is small and the wear resistance is good;
7) having a softness combined with the sealing surface;
8) Good aging resistance and durability;
9) Convenient processing and manufacturing, low price and easy material selection.
