isicelo

Ipayipi le-polyvinyl chloride, elibuye lithi ipayipi le-pvc, liwushubhu lapho kwenziwa khona i-polymer ephezulu ye-thermal plasticity eyakhiwe yi-polymerization ye-vinyl choride monomer, ithatha i-polyvinyl chloride (PVC) RESINS njengento eluhlaza, engeza i-ejenti evimbela ukuguga, i-ejenti yokulungisa izakhiwo. njll., izinto ezakha ngokusebenzisa amasu anjengokuxuba, i-calendering, ukwakheka kwe-vacuum.

Ipayipi le-Pvc ukumelana nokugqwala kunamandla, kuyabophezela ukuba kube lula, i-PVC inokungazweli okunamandla kwe-oxygenant, i-reductive agent kanye ne-asidi eqinile. uwoyela, i-nitric acid egxilile nge-acid oxidizing acid.

Kodwa, ipayipi le-pvc, ikakhulukazi ukushisa kwamapayipi e-UPVC akubi kahle, futhi amandla aqinile emvelo ehla ngaphezu kuka-60 ℃, futhi ngaphansi kwezinga lokushisa eliphansi, ukumelana nokudubula kwamanzi e-Vybak kunciphisa ukushaqeka kunciphisa. ukudabuka;Ngaphezu kwalokho, ukusebenza ipayipi le-pvc elimelana nokushaqeka nakho kubi.

Uhlobo lwamapayipi e-polychlorethylene aqine kakhulu, okumele enziwe yingxenye yengxenye yesisindo elandelayo:
