Phapang pakeng tsa liphaephe tsa UPVC le PVC le tsona li fetela ho thepa.Li-plasticizers li sebelisoa liphaepheng tsa PVC, 'me li-phthalate ke tsona tse atileng haholo.Li-plasticizers tsena le tse ling ha li na monko ebile ha li na 'mala.Ha li behiloe ka PVC, li etsa hore phala e hlahisoe e kobehe le ho tenyetseha ka ho ntlafatsa ho feto-fetoha ha maemo ka kakaretso.UPVC ha e na li-plasticizers, hape UPVC ha e na BPA ea PVC.
Li-plasticizers li etsoa ha li-acids le joala li arabela ka lik'hemik'hale.Li-acid tse sebelisoang hangata li kenyelletsa phthalic anhydride le adipic acid.Ho na le mefuta e fapaneng ea lino tse tahang, 'me motsoako oa li-acids le lino tse tahang li sebelisoa ho fumana mefuta ea li-ester le li-plasticizers tse ka etsoang.

PVC e sebelisoa haholo ho nkela liphaephe tsa khale tsa tšepe sebaka, liphaephe tsa samente, joalo-joalo lits'ebetsong tsa nosetso, liphaephe tsa metsi a litšila le lits'ebetso tsa matamo.Ho sebelisa sekhomaretsi ho ka sebelisoa ho e lokisa, e leng se loketseng bakeng sa kaho.UPVC e tsebahala ka khanyetso ea eona ea lik'hemik'hale.E boetse e thusa ho netefatsa phallo ea metsi e lekaneng ka lebaka la marako a ka hare a boreleli.E thata ho feta PVC, empa e nkoa e le matla, e etsa hore e hanyetsane le likhatello tse fapaneng tsa ts'ebetso le mocheso.

Mefuta ena ka bobeli ea liphaephe e sebetsanoa ka mokhoa o ts'oanang.Lisebelisoa tse ling tsa matla a ho seha PVC le li-hacksaw tsa polasetiki li loketse mefuta e 'meli ea liphaephe.Phapang pakeng tsa tse peli e amana le ho feto-fetoha ha boholo.Ka mohlala, haeba PVC e sa khaoloa hantle, ho tenyetseha ha eona ho e lumella hore e lule e lekana hantle.Leha ho le joalo, ka uPVC, e tlameha ho khaoloa ho isa litekanyong tse nepahetseng kapa e ke ke ea sebetsa molemong oa ts'ebeliso e reriloeng.Sena ke hobane e thata ebile ha e khone ho otlolla hanyenyane joalo ka PVC.

Ha ho hahoa, mefuta e 'meli ea polasetiki e sebelisoa ho etsa mefuta e mengata ea liphaephe.Ka mohlala, lipeipi tse kholoanyane tsa PVC li ka sebelisoa ho thusa ho tsamaisa metsi a sa noeeng.Tšebeliso e 'ngoe e tloaelehileng ke ea lithapo, moo boholo ba PVC bo fanang ka insulation e eketsehileng.
Kahong, uPVC ke sebaka se loketseng bakeng sa patsi maemong a mangata.Ka mohlala, e ka sebelisoa ho etsa liforeimi tsa lifensetere tse tšoarellang haholoanyane le tse khonang ho mamella likarolo tse ntle ho feta lehong.PVC ea kamehla e ke ke ea sebelisoa ho etsa liforeimi tsa lifensetere.Sena ke hobane uPVC ha e bole, empa PVC e tloaelehileng ea etsa joalo.PVC e tloaelehileng ha e thibane letlalo joalo ka UPVC.Ba sebetsang kahong le bona ba ka sebelisa thepa ena sebakeng sa tšepe e entsoeng ka tšepe bakeng sa drainage e boima le lipeipi tsa metsi
