Can cpvc pipe be bonded with upvc pipeStrictly speaking, it is not allowed, because pipes of different materials use different glues. But when the pressure is below 0.3MPa, it can be bonded. But use good glue.
Resin is made of polyvinyl chloride (PVC) resin through chlorination modification, and is a new type of engineering plastic. The product is white or light yellow loose particles or powder which is odorless, odorless and non-toxic. After chlorination of PVC resin, the irregularity of molecular bonds increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the heat resistance, acid resistance, alkali, salt, oxidizing agent, etc. corrosion. The mechanical properties of the heat distortion temperature have been improved, the chlorine content has been increased from 56.7% to 63-69%, the Vicat softening temperature has been increased from 72-82 ℃, (increased to 90-125 ℃), the maximum operating temperature can reach 110 ℃ , The long-term use temperature is 95 ℃. Among them, the performance index of CORZAN CPVC is better. Therefore, CPVC is a new engineering plastic with broad application prospects.
The tube uses polyvinyl chloride resin as a carrier, which has excellent characteristics such as accurate temperature sensitivity, timed melting, and rapid absorption of the active ingredients of additives when weakening the attraction between the resin molecular chains. The resin can trap, suppress, absorb and neutralize the hydrogen chloride during the high temperature and melting process, and perform a double bond addition reaction with the polyene structure to replace the active and unstable chlorine atoms in the molecule. So as to effectively and scientifically control the catalytic degradation and oxidative decomposition of the resin in the molten state.
