PVC e emetse polyvinyl chloride mme ke thepa e fapaneng e sebelisoang haholo ha ho etsoa. E atisa ho sebelisoa ha ho etsoa liphaephe, lithapo, liaparo le liphutheloana, har'a lisebelisoa tse ling tse ngata. E 'ngoe ea lisebelisoa tsa bohlokoa tse netefatsang ho tšoarella le ts'ebetso ea lihlahisoa tsa PVC ke li-stabilizers tsa PVC.
Li-stabilizers tsa PVCke li-additives tse kopantsoeng le PVC nakong ea ts'ebetso ea tlhahiso ea PVC ho thibela ho senyeha ha thepa ho bakoang ke mocheso, mahlaseli a UV le mabaka a mang a tikoloho. Sena se bohlokoa ho etsa bonnete ba hore lihlahisoa tsa PVC li na le nako e telele ea ho sebetsa 'me li ka mamella mathata a ts'ebeliso ea 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. Ka mohlala, li-stabilizers tsa mocheso li sebelisetsoa ho sireletsa PVC ho tloha mocheso o phahameng, ha li-stabilizer tsa UV li thusa ho thibela thepa hore e se ke ea senyeha ha e pepesehetse letsatsi. Mefuta e meng ea li-stabilizers e kenyelletsa litlolo, li-modifiers le lithuso tsa ho sebetsa, tseo kaofela li phethang karolo ea ho ntlafatsa ts'ebetso le bophelo ba ts'ebeletso ea lihlahisoa tsa PVC.
Lefapheng la kaho, li-stabilizers tsa PVC li bohlokoa ka ho khetheha ho netefatsa ho tšoarella ha liphaephe le lisebelisoa tsa PVC. Lihlahisoa tsena li atisa ho sebelisoa lits'ebetsong tsa liphaephe tse pepesehileng mefuta e mengata ea mocheso le likhatello. Ntle le li-stabilizers tse nepahetseng, liphaephe tsa PVC li ka senyeha 'me tsa pepera habonolo, tsa baka ho lutla le litokiso tse ka bitsang chelete e ngata.
Ka mokhoa o ts'oanang, indastering ea likoloi,Li-stabilizers tsa PVCli sebelisoa ha ho etsoa lithapo le likhoele tsa terata. Likarolo tsena li atisa ho angoa ke mocheso le ho thothomela, 'me boteng ba li-stabilizers bo tiisa hore ho kenngoa ha PVC ho lula ho tiile le ho tšepahala bophelong bohle ba koloi.
Lefapheng la thepa ea bareki, li-stabilizer tsa PVC le tsona li bapala karolo ea bohlokoa. Ho tloha mokatong oa 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-stabilizers nakong ea ts'ebetso ea tlhahiso, lihlahisoa tsena li boloka ponahalo ea tsona le ts'ebetso ea tsona ka lilemo, esita le libakeng tse thata.
Ke habohlokoa ho hlokomela hore tšebeliso ea li-stabilizers tsa PVC e boetse e tataisoa ke litekanyetso tsa taolo ho netefatsa tšireletso le phello ea tikoloho ea lihlahisoa tsa PVC. Ka mohlala, mefuta e itseng ea li-stabilizers, tse kang li-stabilizer tse nang le loto, li ntse li tlosoa libakeng tse ngata ka lebaka la ho tšoenyeha ka chefo ea tsona. Ka lebaka leo, bahlahisi ba ntse ba fetohela ho li-stabilizer tse ling tse fanang ka ts'ebetso e ts'oanang empa ntle le likotsi tse ka bang teng tsa bophelo bo botle.
Kahoo, li-stabilizer tsa PVC ke li-additives tsa bohlokoa tse thusang ho ntlafatsa ts'epo le bophelo ba ts'ebeletso ea lihlahisoa tsa PVC liindasteri tse fapaneng. Ka ho sireletsa PVC ho senyeha ho bakoang ke mocheso, mahlaseli a UV le lintho tse ling tsa tikoloho, li-stabilizers li tiisa hore lihlahisoa tsa PVC li tsoela pele ho sebetsa ka katleho bakeng sa tšebeliso ea tsona. Ha tlhoko ea thepa e tšoarellang le e tšoarellang e ntse e hola, karolo ea li-stabilizer tsa PVC ho khothaletseng ts'ebeliso e pharalletseng ea PVC e ntse e le bohlokoa joalo ka mehleng.
