I. āhuatanga rauemi:
Ko te PVC he mea hanga mai i te vinyl chloride monomer (VCM) polymerization, he mea kore-paitini, he anti-hoholo me te waikawa me te alkali, he mea tino pai mo te whakamahi i te pipeline matū.A ki te PVC rauemi mata ki te tāpiri i te nui etahi o tāpiritanga totoka (kahore plasticizer) hanganga o te ranunga, ka karanga polyvinyl pūhaumāota (e kiia ana ko UPVC).
Ko te CPVC he mea waerau i whakarereketia e te whakamaaramatanga o te polyvinyl chloride (PVC) ano.I muri i te chlorination, ka piki ake te ihirangi chlorine o te PVC resin mai i te 56.7% ki te 63-69%, e whakanui ana i te pumau matū me te whakapai ake i te kaha o te wera me te waikura o te waikawa, te alkali, te tote me te waikura o te rauemi.He nui ake te ahua o te wera o te waiariki me nga taonga miihini i era o UPVC.Na reira, ko te CPVC tetahi o nga rawa miihini pai rawa atu mo nga pipeline ahumahi.
2. whakaurunga pūnaha paipa:
UPVC me te CPVC pipeline pūnaha he waikura ātete, pānga ātete, e kore e ngāwari ki te deformation, pakitara o roto maeneene, e kore e ngāwari ki te āwhatatia, waiariki marara pai, kore-conductive, here watea, te ora ratonga roa me ētahi atu āhuatanga.Na reira, ka whakakapihia e ia etahi atu punaha paipa whakarewa i runga i nga painga o te utu nui me te iti o te utu hanga, a ko nga punaha paipa UPVC me CPVC he watea, he tere hoki te tiaki, kaore he wa roa me nga mate nui, no reira ko nga punaha paipa UPVC me CPVC te whiriwhiri tuatahi. mo te hoahoa paipa ahumahi o naianei.
Ko te teitei o te pāmahana ratonga e whakaaetia ana mo te punaha paipa UPVC he 60 ℃, ko te pāmahana ratonga mo te wa roa ko te 45 ℃.He pai mo te kawe i etahi purongo kino me te pāmahana iti iho i te 45 ℃;Ka taea hoki te whakamahi mo te kawe i te wai pehanga noa, i te nuinga o te waa e whakamahia ana i roto i te tuku wai me te paipa wai, nga pipelines irrigation ahuwhenua, pipelines engineering taiao, pipelines rangi me te pera i runga i.
Ko te 110 ℃ te pāmahana ratonga e whakaaetia ana mo te punaha paipa CPVC, me te 95 ℃ te pāmahana ratonga mo te wa roa.He pai mo te kawe i te wai wera me nga purongo kino i roto i te awhe pehanga e whakaaetia ana o te paerewa.I te nuinga o te wa e whakamahia ana i roto i te hinu, te matū, te hiko, te hiko hiko, te whakarewa, te pepa, te kai me te inu, te rongoa, te whakakikorua me etahi atu mara ahumahi.
