上海淞江减震器集团有限公司介绍：PVC法兰DN125橡胶避震喉产品信息，淞江集团为众多海洋馆维生系统提高各种管道减震器产品，以下是单球PVC法兰橡胶接头介绍。

Shanghai Songjiang shock absorber Group Co., Ltd. introduces: PVC flange DN 125 rubber shock absorber throat product information. Songjiang group improves various pipeline shock absorber products for many aquarium life support systems. The following is the introduction of single ball PVC flange rubber joint.

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。

PVC is a white powder with amorphous structure and small degree of branching. Its glass transition temperature is 77 ~ 90 ℃, and it begins to decompose at about 170 ℃. It has poor stability to light and heat. It will decompose above 100 ℃ or after a long time of sun exposure to produce hydrogen chloride, which will be further Autocatalytic Decomposition, causing discoloration and rapid decline of physical and mechanical properties. In practical application, stabilizer must be added to improve the stability High thermal and light stability.
