上海淞江减震器集团有限公司介绍：塑料法兰PVCDN125橡胶避震接头信息，淞江集团为众多海洋馆维生系统提供各种管道减震器产品，以下是单球PVC法兰橡胶接头介绍。
PVC为无定形结构的白色粉末，支化度较小，玻璃化温度77~90℃，170℃左右开始分解，对光和热的稳定性差，在100℃以上或经长时间阳光曝晒，就会分解而产生氯化氢，并进一步自动催化分解，引起变色，物理机械性能也迅速下降，在实际应用中必须加入稳定剂以提高对热和光的稳定性。
橡胶避震接头特点：体积小、重量轻、弹性好、安装维修方便。安装后可吸收管道震动产生的横向、轴向、角向位移；不受管道不同心，法兰不平行的限制。安装后可降低管道水泵等震动产生的噪音，吸振能力强。内无缝高压橡胶接头，在耐高温、耐酸碱、耐油的管道中更有效地防止了腐蚀性介质对橡胶接头内壁的侵蚀，提高了使用寿命。
Shanghai Songjiang shock absorber Group Co., Ltd. introduces: plastic flange pvcdn125 rubber shock absorber joint information. Songjiang group provides various pipeline shock absorber products for many aquarium life support systems. The following is the introduction of single ball PVC flange rubber joint.
PVC is a white powder with amorphous structure. Its branching degree is small. The glass transition temperature is 77 ~ 90 ℃, and it starts to decompose at about 170 ℃. The stability to light and heat is poor. When the temperature is above 100 ℃ or after a long time of exposure to the sun, it will decompose and produce hydrogen chloride, which will further catalyze the decomposition, cause discoloration, and rapidly reduce the physical and mechanical properties High stability to heat and light.
Rubber shock absorber joint features: small volume, light weight, good elasticity, easy installation and maintenance. After installation, it can absorb the lateral, axial and angular displacement caused by pipeline vibration, and is not limited by the pipe misalignment and flange parallelism. After installation, it can reduce the noise caused by vibration of water pump and pipeline, and has strong vibration absorption capacity. The inner seamless high-pressure rubber joint can effectively prevent the corrosion of corrosive medium on the inner wall of rubber joint in the pipeline with high temperature resistance, acid and alkali resistance and oil resistance, so as to improve the service life.
