Melemo ea liphaephe tsa metsi tsa PVC:
⑴ E na le matla a matle a ho tsitsa le ho hatella.
⑵ Ho hanyetsa mokelikeli o tlase:Lerako la UPVCliphaephe li boreleli haholo 'me li na le khanyetso e nyane ho mokelikeli. Coefficient ea eona e boima ke 0.009 feela. Ho feta moo, matla a phetiso ea metsi a ka eketsoa ka 20% ha a bapisoa le liphaephe tsa tšepe tse nang le bophara bo lekanang le 40% ha li bapisoa le lipeipi tsa konkreite.
⑶ Ho hanyetsa kutu e ntle haholo le khanyetso ea lik'hemik'hale: liphaephe tsa UPVC li na le asiti e ntle haholo le khanyetso ea alkali le ho hanyetsa kutu. Ha li amehe ke mongobo le mobu oa PH, kahoo ha ho na phekolo e khahlanong le kutu e hlokahalang ha ho behoa liphaephe.
⑷ Thibelo e ntle ea metsi: Ho kenngoa ha liphaephe tsa UPVC ho na le ho thibela metsi hantle ho sa tsotellehe hore na ho kopantsoe ka li-rings tsa bonding kapa rabara.
⑸ Anti-loma: Kaha liphaephe tsa UPVC ha se mohloli oa phepo, li ke ke tsa senngoa ke likhoto.

Liphaephe tse nyenyane tsa polasetiki tsa PVC li sebelisoa haholo-holo e le lipeipi tsa metsi tsa malapa, tse mahareng li ka sebelisoa e le lipeipi tsa metsi a ka tlas'a lefatše, 'me tse nang le bophara bo boholo li ka sebelisoa e le lipeipi tsa metsi bakeng sa Morero oa Phalliso ea Metsi a Boroa ho ea Leboea. Ho boetse ho na le phala e nyane ea polasetiki ea PVC e ka sebelisoang e le phala ea phepelo ea matla.
Haeba pipe ea PVC e hlahisoang ka tšohanyetso e fetoha mosehla, ho hlokahala hore u hlahlobe bothata ba thepa ea tlhahiso ea pipe ea PVC.
1. Haeba ho na le bothata ka thermocouple kapa fan, e tla etsa hore moqomo o chese haholo sebakeng sa heno mme o etse hore sehlahisoa se fetohe mosehla, ke hore, se chese ebe se fetoha mosehla. Tharollo: Lekola hore na li-thermocouples sebakeng se seng le se seng sa barrel li sebetsa hantle le hore na libapali sebakeng ka seng li sebetsa ka mokhoa o tloaelehileng.
2. Haeba potoloho ea oli e koetsoe, mocheso oa friction oa screw o ke ke oa lokolloa ka katleho, e leng se tla etsa hore sekoti se chese ebe se etsa hore thepa e senyehe ebe e fetoha mosehla.
