Ingabe ukufakwa kwe-PVC kanye ne-CPVC okufanayo?

Lapho ukhetha izinto zokufaka amapayipi, ukunisela, noma amasistimu wezimboni, ungahlangabezana nezinketho ezimbili ezifanayo: PVC (polyvinyl chloride) kanye Ukufakwa kwamaphayiphu we-CPVC(Chlorinated polyvinyl chloride). Ngenkathi babelana ngokufana okuthile, bahlukile ezakhiweni zabo, izinhlelo zokusebenza, kanye namakhono okusebenza. Ukuqonda lokhu kwehluka kubalulekile ukuze uqinisekise impumelelo nokuphepha kwephrojekthi yakho.

Yini i-PVC ne-CPVC?

I-PVC iyinto esetshenziswa kabanzi yepulasitiki eyaziwa ngokuqina kwayo, ukufinyeleleka, kanye nokuguquguquka okuhlukahlukene. Sekuyisisekelo ekwakhiweni nasekufakwe ngamapayipi, ikakhulukazi izicelo ezibandakanya amanzi abandayo noma izinhlelo eziphansi zengcindezi. Ngakolunye uhlangothi, i-CPVC, iyindlela eguquliwe ye-PVC eye yangezelela inqubo eyengeziwe ye-chlorination. Le nqubo inyusa okuqukethwe kwe-chlorine ye-CPVC, ukuthuthukisa ukumelana kwayo okushisayo nokwekhemikhali.

Yize zithathwe zombili kusuka esisekelweni esifanayo se-polymer, umehluko ekwakhiweni kwabo kuholela ekuhlukahlukani okuphambili ekusebenzeni nasekusebenzeni.

I-Leyon CPVC Fittings

Umehluko Osemqoka phakathi kwama-PVC kanye ne-CPVC

1. Ukumelana Nezinga

Enye yokuhlukaniswa okubucayi kakhulu phakathi kwe-PVC ne-CPVC yikhono labo lokumelana nokushisa.

• I-PVC Fittings:I-PVC ilungele izinhlelo lapho izinga lokushisa eliphakeme lingadluli ku-140 ° F (60 ° C). Ilungele izinhlelo zamanzi abandayo, ukunisela kwangaphandle, kanye nezicelo zokudonsa. Kodwa-ke, ukuvezwa kumazinga okushisa aphezulu kungakwenza buthaka okuqukethwe, okuholela ekunciphiseni noma kuvuza.
• Ukufakwa kwe-CPVC:I-CPVC ingaphatha amazinga okushisa aphakeme ngo-200 ° F (93 ° C), okwenza kube lulungele amapayipi amanzi ashisayo, amapayipi ezimboni, ngisho nezinhlelo zomlilo zokufafaza. Lokhu kumelana nokushisa kungumphumela we-chlorination yayo eyengeziwe, eqinisa isakhiwo se-polymer.

2. Ukuvumelana Kwamakhemikhali

Enye into ebalulekile ukuthi izinto zokwakha zisabela kanjani kumakhemikhali ahlukahlukene.

• I-PVC Fittings:Ngenkathi i-PVC imelana namakhemikhali ahlukahlukene, ayifanelekile ezindaweni ezinama-acidic noma ezilonakalisayo. Ukuchayeka isikhathi eside kumakhemikhali athile kungalimaza isakhiwo salo ngokuhamba kwesikhathi.
• Ukufakwa kwe-CPVC:I-CPVC inikeza ukumelana kwamakhemikhali okuphezulu, kufaka phakathi ukumelana nama-acid aqinile, izisekelo, nosawoti. Lokhu kwenza kube ukukhetha okuhle kakhulu kwezicelo zezimboni ezinjengezinhlelo zamakhemikhali zokuhamba namanzi angcolile.

3. Ukubonakala ngokomzimba nokukhonjwa

Ngokubona, i-PVC ne-CPVC ngokuvamile kungahlukaniswa ngombala wazo:

• Ukufakwa kwe-PVCzivame ukumhlophe noma zimpunga.
• Ukufakwa kwe-CPVCzivame ukuba seTan, beige, noma ophuzi.

Ngokwengeziwe, ukufakwa kwe-CPVC kuvame ukuza ngokumaka okuthile okukhombisa izinga lokushisa nokucindezela kwabo. Lezi zimaka zisiza ekuqinisekiseni ukuthi okuqukethwe kusetshenziswa kahle kwizicelo ezifanele.

4. Izindleko nokutholakala

• I-PVC Fittings:Ngoba i-PVC idinga izinyathelo ezimbalwa zokucubungula, ngokuvamile iyabiza kakhulu futhi itholakala kabanzi.
• Ukufakwa kwe-CPVC:I-CPVC ibiza kakhulu ngenxa yenqubo eyengeziwe ye-chlorination kanye nezakhiwo ezisebenzayo ezithuthukisiwe. Kodwa-ke, izindleko zayo eziphakeme kufanelekile kuhlelo lokusebenza lapho izinga lokushisa kanye nokumelana kwamakhemikhali zibucayi.

5. Ukuqinisekiswa kanye Nezicelo

Zombili lezi zinto zinezitifiketi namazinga athile okusetshenziswa. Kodwa-ke, ukufakwa kwe-CPVC kuvame ukuqinisekiswa ukusetshenziswa ezinhlelweni ezikhethekile ezifana nezinhlelo zokufafaza umlilo noma amasistimu wamanzi ashisayo.

• I-PVC ilungele:
  • Amapayipi wamanzi abandayo
  • Izinhlelo zokunisela
  • Izinhlelo zokudonsa okuphansi kwengcindezi
• I-CPVC ilungele:
  • Amapayipi amanzi ashisayo
  • Izinhlelo zokucindezela umlilo
  • Amapayipi ezimboni ngokuvezwa kwamakhemikhali

Ngabe bayashintshana?

Yize i-PVC ne-CPVC ingabukeka ifana, ayiguquki ngenxa yezakhiwo zazo ezihlukile. Isibonelo, ukusebenzisa i-PVC endaweni yokushisa ephezulu kungaholela ekuhlulekeni ngokwezinto ezibonakalayo kanye nezingozi zokuphepha ezingaba khona. Ngokufanayo, usebenzisa i-CPVC esimweni lapho izakhiwo zayo ezithuthukisiwe zingadingeki zingahle ziholele ezindlekweni ezingadingekile.

Ngaphezu kwalokho, ama-adhesives asetshenziselwa ukujoyina i-PVC ne-CPVC ahlukile. Ama-solvents ku-PVC usimende kungenzeka angakha isibopho esivikelekile ngezinto zokwenziwa ze-CPVC, kanye okuphambene nalokho. Njalo qiniseka ukuthi usebenzisa usimende ofanele kanye ne-primer yezinto ezithile.
