PVC e emetse polyvinyl chloride mme ke thepa e feto-fetohang e sebediswang haholo tlhahisong. E sebediswa haholo tlhahisong ya diphaephe, dikheibole, diaparo le diphutheloana, hara dikopo tse ding tse ngata. E nngwe ya metswako ya bohlokwa e netefatsang ho tshwarella le tshebetso ya dihlahiswa tsa PVC ke di-stabilizer tsa PVC.
Li-stabilizer tsa PVCke di-additives tse tswakilweng le PVC nakong ya tshebetso ya tlhahiso ya PVC ho thibela ho senyeha ha thepa ho bakwang ke mocheso, mahlasedi a UV le mabaka a mang a tikoloho. Sena se bohlokwa ho netefatsa hore dihlahiswa tsa PVC di na le nako e telele ya ho boloka dintho mme di ka mamella mathata a tshebediso ya letsatsi le letsatsi.
Ho na le mefuta e fapaneng ea li-stabilizer tsa PVC, e 'ngoe le e 'ngoe e etselitsoe ho rarolla mathata a itseng. Mohlala, li-stabilizer tsa mocheso li sebelisoa ho sireletsa PVC mochesong o phahameng, ha li-stabilizer tsa UV li thusa ho thibela thepa hore e se ke ea senyeha ha e pepesetsoa khanya ea letsatsi. Mefuta e meng ea li-stabilizer e kenyelletsa li-lubricant, li-impact modifiers le lithuso tsa ts'ebetso, tseo kaofela li phethang karolo ho ntlafatseng ts'ebetso le bophelo ba ts'ebeletso ea lihlahisoa tsa PVC.
Indastering ea kaho, li-stabilizer tsa PVC li bohlokoa haholo ho netefatsa hore liphaephe le lisebelisoa tsa PVC li tšoarella nako e telele. Lihlahisoa tsena li sebelisoa hangata lits'ebetsong tsa liphaephe tse pepesetsoang mocheso le khatello e fapaneng. Ntle le li-stabilizer tse nepahetseng, liphaephe tsa PVC li ka robeha habonolo 'me tsa petsoha, tsa baka ho lutla le litokiso tse ka bang theko e boima.
Ka ho tšoanang, indastering ea likoloi,Li-stabilizer tsa PVCdi sebediswa tlhahisong ya dithapo le dithapo tsa terata. Dikarolo tsena hangata di angwa ke mocheso le ho thothomela, mme boteng ba di-stabilizer bo netefatsa hore ho kwahela ha PVC ho dula ho sa senyeha ebile ho tshepahala bophelong bohle ba koloi.
Lefapheng la thepa ea bareki, li-stabilizer tsa PVC le tsona li bapala karolo ea bohlokoa. Ho tloha fatše la vinyl ho ea ho liforeimi tsa lifensetere, PVC ke khetho e tsebahalang ka lebaka la ho tšoarella ha eona le litlhoko tse tlase tsa tlhokomelo. Ka ho kenyelletsa li-stabilizer nakong ea ts'ebetso ea tlhahiso, lihlahisoa tsena li boloka ponahalo le ts'ebetso ea tsona ka lilemo tse ngata, esita le libakeng tse thata.
Ho bohlokoa ho hlokomela hore tšebeliso ea li-stabilizer tsa PVC e boetse e tataisoa ke litekanyetso tsa taolo ho netefatsa tshusumetso ea polokeho le tikoloho ea lihlahisoa tsa PVC. Mohlala, mefuta e itseng ea li-stabilizer, joalo ka li-stabilizer tse thehiloeng ho loto, e ntse e felisoa libakeng tse ngata ka lebaka la matšoenyeho mabapi le chefo ea tsona. Ka lebaka leo, bahlahisi ba ntse ba retelehela ho li-stabilizer tse ling tse fanang ka ts'ebetso e ts'oanang empa li se na likotsi tse ka bang teng bophelong.
Kahoo, li-stabilizer tsa PVC ke lintho tsa bohlokoa tse thusang ho ntlafatsa ts'epo le bophelo ba ts'ebeletso ea lihlahisoa tsa PVC liindastering tse fapaneng. Ka ho sireletsa PVC ho senyeha ho bakoang ke mocheso, mahlaseli a UV le mabaka a mang a tikoloho, li-stabilizer li netefatsa hore lihlahisoa tsa PVC li tsoela pele ho sebetsa ka katleho bakeng sa ts'ebeliso ea tsona e reriloeng. Ha tlhoko ea thepa e tšoarellang le e tšoarellang e ntse e hola, karolo ea li-stabilizer tsa PVC ho khothaletseng ts'ebeliso e pharaletseng ea PVC e ntse e le ea bohlokoa joalo ka mehleng.
