2. Molemo oa lakane e tiileng ea PVC ke ofe?
Maqephe a PVC a tiileng a na le melemo e mengata e kang ho hanyetsa mafome, ho se chese, ho thibela mocheso le ho hanyetsa oxidation. Ho phaella moo, a ka sebetsoa hape mme a ba le litšenyehelo tse tlase tsa tlhahiso. Ka lebaka la mefuta e mengata ea ts'ebeliso le litheko tse theko e tlase, esale a le karolo ea 'maraka oa maqephe a polasetiki. Hona joale, theknoloji ea ntlafatso le moralo oa maqephe a PVC naheng ea rona e fihlile boemong bo tsoetseng pele ba machaba.
3. Tšebeliso ea lakane ea PVC ke efe?
Maqephe a PVC a na le mekhoa e mengata haholo, 'me ho na le mefuta e fapaneng ea maqephe a PVC, joalo ka maqephe a bonaletsang a PVC, maqephe a PVC a nang le serame, maqephe a PVC a matala, meqolo ea maqephe a PVC, jj. Ka lebaka la ts'ebetso ea eona e ntle ea ts'ebetso, litšenyehelo tse tlase tsa tlhahiso, ho hanyetsa mafome le ho thibela ho ruruha. Maqephe a PVC a sebelisoa haholo 'me a sebelisoa haholo ho etsa: likoahelo tsa ho tlama tsa PVC, likarete tsa PVC, lifilimi tse thata tsa PVC, maqephe a PVC a thata, jj.
4. Bothata ba lakane ea PVC ke bofe?
Letlapa la PVC le lona ke polasetiki e sebelisoang haholo. Ke resin e entsoeng ka resin ea polyvinyl chloride, plasticizer, le antioxidant. Ha e na chefo ka boeona. Empa lisebelisoa tse ka sehloohong tse thusang tse kang li-plasticizer le li-antioxidants li na le chefo. Li-plasticizer tse polasetiking ea letsatsi le letsatsi ea PVC li sebelisa haholo-holo dibutyl terephthalate le dioctyl phthalate. Lik'hemik'hale tsena li na le chefo. Lead stearate ea antioxidant e sebelisoang ho PVC le eona e na le chefo. Maqephe a PVC a nang le letsoai la lead antioxidants a tla baka loto ha a kopana le li-solvents tse kang ethanol le ether. Maqephe a PVC a nang le loto a sebelisoa bakeng sa ho paka lijo. Ha a kopana le lithupa tsa hlama e halikiloeng, likuku tse halikiloeng, tlhapi e halikiloeng, lihlahisoa tsa nama e phehiloeng, li-pastry le lijo tse bobebe, jj., limolek'hule tsa loto li tla hasana ka har'a oli. Ka hona, mekotla ea polasetiki ea PVC e ke ke ea sebelisoa ho tšoara lijo, haholo-holo oli e nang le lijo. Ho phaella moo, lihlahisoa tsa polasetiki tsa polyvinyl chloride li tla senya khase ea hydrogen chloride butle-butle mochesong o phahameng, joalo ka hoo e ka bang 50°C, e leng kotsi 'meleng oa motho.
