Ho Utloisisa Matlotlo a Thepa ea Liphaephe tsa Plastiki
Ha o hlahloba thepa ea liphaephe tsa polasetiki, nahana ka litšobotsi tsena tsa bohlokoa:
Matla le Khanyetso ea Tšusumetso: Thepa e lokela ho mamella khatello, tšusumetso le matla a kantle ntle le ho petsoha kapa ho robeha.
Ho Hanela Mocheso: Thepa e lokela ho boloka botsitso ba eona maemong a fapaneng a mocheso, ho kenyeletsoa mocheso o feteletseng kapa serame.
Ho Hanela Lik'hemik'hale: Thepa e lokela ho hanela ho bola ho tsoa lik'hemik'haleng, li-solvents le lintho tse ling tseo e ka 'nang ea kopana le tsona.
Khanyetso ea UV: Thepa e lokela ho mamella ho pepesehela mahlaseli a ultraviolet a tsoang khanya ea letsatsi ntle le ho senyeha.
Litšobotsi tsa Phallo: Thepa e lokela ho netefatsa phallo e boreleli le ho fokotsa tahlehelo ea khohlano ho ntlafatsa phetisetso ea mokelikeli.
Lisebelisoa tse Hloahloa bakeng sa Tlhahiso ea Liphaephe tsa Plastiki
Polyvinyl Chloride (PVC): PVC ke polasetiki e feto-fetohang le e sebelisoang haholo e tsejoang ka theko ea eona e tlase, matla le ho hanyetsa lik'hemik'hale. E sebelisoa hangata phepelong ea metsi a nooang, likhoerekhoere le lits'ebetsong tsa ho ntša metsi.
Polyethylene e nang le Botenya bo Holimo (HDPE): HDPE e tsebahala ka ho tšoarella ha eona ka tsela e ikhethang, ho tenyetseha, le ho hanyetsa tšusumetso, lik'hemik'hale le mahlaseli a UV. E sebelisoa khafetsa kabong ea khase, nosetsong ea temo le lits'ebetsong tsa indasteri.
Polypropylene (PP): PP e nkoa e le ea bohlokoa ka lebaka la matla a eona a phahameng, ho hanyetsa lik'hemik'hale, le bokhoni ba ho mamella mocheso o phahameng. E sebelisoa hangata liphaepheng tsa metsi a chesang, liphaepheng tsa khatello le lits'ebetsong tsa lik'hemik'hale.
Acrylonitrile Butadiene Styrene (ABS): ABS e fana ka motsoako oa matla, ho hanyetsa tšusumetso, le ho mamella maemo a leholimo, e leng se etsang hore e lokele ho kenngoa liphaepheng tse pepeneneng le lits'ebetsong tse hlokang ho hanyetsa tšusumetso e phahameng.
Chlorinated Polyvinyl Chloride (CPVC): CPVC e fana ka khanyetso e matla ea lik'hemik'hale le mamello e phahameng ea mocheso ha e bapisoa le PVC, e leng se etsang hore e be ntle bakeng sa lits'ebetso tsa indasteri tse kenyeletsang lik'hemik'hale tse matla kapa mocheso o phahameng.
Ho Khetha Boitsebiso bo Nepahetseng bakeng sa Kopo ea Hao
Khetho ea thepa ea phaephe ea polasetiki e itšetlehile ka ts'ebeliso e itseng le litlhoko tsa eona. Nahana ka lintlha tsena ha u etsa qeto ea hau:
Litlhoko tsa Khatello: Lekola tekanyo ea khatello ea thepa ea phaephe ho netefatsa hore e ka mamella maemo a khatello a lebelletsoeng ts'ebelisong ea hau.
Maemo a Thempereichara: Fumana hore na ke mocheso o tlase le o phahameng ka ho fetisisa oo phaephe e tla pepesetsoa ho oona ebe o khetha thepa e nang le mamello e loketseng ea mocheso.
Ho Hlahisoa ke Lik'hemik'hale: Hlalosa lik'hemik'hale kapa lintho tseo phaephe e ka kopanang le tsona 'me u khethe thepa e nang le khanyetso e hlokahalang ea lik'hemik'hale.
Maemo a Tikoloho: Nahana ka mabaka a tikoloho, a kang ho pepesehela mahlaseli a kotsi a letsatsi kapa likotsi tse ka bang teng tsa tshusumetso, 'me u khethe thepa e nang le litšobotsi tse loketseng tsa ho hanyetsa.
Qetello
Liphaephe tsa polasetiki li fana ka melemo e mengata ho feta liphaephe tsa tšepe tsa setso, e leng se etsang hore e be khetho e tsebahalang bakeng sa lits'ebetso tse fapaneng. Ka ho utloisisa litšobotsi tsa thepa e fapaneng ea liphaephe tsa polasetiki le ho khetha e nepahetseng bakeng sa litlhoko tsa hau tse ikhethileng, u ka netefatsa ho tšoarella, ts'ebetso, le boleng ba nako e telele ba sistimi ea hau ea liphaephe.
