isicelo

Umbhobho we-Polyvinyl chloride, ekwabanga umbhobho we-pvc, yityhubhu eyenziwa yi-polymerization ye-vinyl choride monomer eyenziwe nge-vinyl chloride, ithatha i-polyvinyl chloride (PVC) RESINS njengeyona nto iphambili, yongeza i-ejenti efanelekileyo yokuguga, i-arhente yokulungisa izakhiwo. njl., izinto ezenziwe ngobuchule obufana nokuxuba, i-calendering, i-vacuum formings.

Ukuxhathisa kombhobho wePvc ekumdleni kunamandla, kuyathandeka ukuba kube lula, i-PVC inamandla okumelana ne-oksijini, i-agent yokunciphisa kunye ne-asidi eqinile. i-oyile, i-nitric acid egxininisiweyo nge-asidi ene-oxidizing.

Kodwa, umbhobho we-pvc, ngokukodwa umbhobho we-UPVC wokuchasana nobushushu awukho mgangathweni, kwaye amandla okusingqongileyo ayancipha ngaphezu kwe-60 ℃, kwaye phantsi kwemekobume yobushushu obuphantsi, ukuxhathisa ukudubula kwamanzi eVybak kwimpembelelo yothutho kuyanciphisa. ukugqabhukaUkongeza, ukusebenza kombhobho we-pvc omelana nokothuka kukwabi.

Uhlobo lwemibhobho ye-polychlorethylene ephezulu yokuqina, ekufuneka yenziwe yinxalenye yobunzima obulandelayo:
