PVC mocheso stabilizersphetha karolo ea bohlokoa ho netefatsa ts'ebetso le ho tšoarella ha lipeipi tsa PVC. Li-stabilizers ke li-additives tse sebelisetsoang ho sireletsa thepa ea PVC ho senyeha ho bakoang ke ho pepesehela mocheso, khanya le oksijene. Sehloohong sena, re tla hlahloba ts'ebeliso ea li-stabilizer tsa mocheso oa PVC liphaepheng tsa PVC le bohlokoa ba tsona bakeng sa ho boloka boleng ba liphaephe.
PVC, kapa polyvinyl chloride, ke lisebelisoa tse fapaneng tse sebelisoang indastering ea kaho bakeng sa lits'ebetso tse fapaneng, ho kenyeletsoa liphaephe, li-fittings le li-conduits. Liphaephe tsa PVC li sebelisoa haholo phepelong ea metsi, drainage, nosetso le lits'ebetso tsa likhoerekhoere ka lebaka la ho tšoarella ha tsona, ho hanyetsa kutu, le ho kenya habonolo. Leha ho le joalo, thepa ea PVC e atisa ho senyeha ha e pepesehile mocheso le khanya, e leng se bakang tahlehelo ea matla a mochine le ho fifala.
Ho hlola phephetso ena, li-stabilizer tsa mocheso oa PVC li sebelisoa ho sireletsa thepa ea PVC ho senyeha ha mocheso nakong ea ts'ebetso le bophelo ba ts'ebeletso ea liphaephe tsa PVC. Sepheo sa li-stabilizers tsena ke ho thibela mekhoa ea ho senyeha e hlahang ha PVC e pepesehela mocheso le khanya, kahoo e lelefatsa bophelo ba tšebeletso ea pipe le ho boloka thepa ea eona ea mechine.
Ho na le mefuta e mengata ea li-stabilizers tsa mocheso tsa PVC tse sebelisetsoang liphaephe tsa PVC, tse kenyelletsang li-stabilizers tse thehiloeng ho loto, li-stabilizer tse thehiloeng ka tin, li-stabilizer tse thehiloeng ka calcium le li-stabilizers tse thehiloeng ho manyolo. Mofuta o mong le o mong oa stabilizer o na le thepa ea oona e ikhethang le melemo, 'me ho khetha se tsitsitseng ka ho fetisisa ho itšetlehile ka litlhoko tse khethehileng tsa kopo ea hau ea pipe ea PVC.
Li-stabilizers tse thehiloeng ho lead, tse kang lead stearate le lead trivalent sulfate, li 'nile tsa sebelisoa haholo nakong e fetileng ka lebaka la botsitso ba tsona bo botle ba mocheso le ho baballa litšenyehelo. Leha ho le joalo, ka lebaka la ho ameha ka tikoloho le bophelo bo botle, linaha tse ngata li khaolitse ho sebelisa li-stabilizer tse nang le loto ’me li nketse sebaka sa tsona tse ling tse etsang botsitso.
Li-stabilizers tse thehiloeng ho tin, tse kang dibutyltin dilaurate le tributyltin oxide, li tsejoa ka botsitso ba tsona bo phahameng ba mocheso le ho hlaka, ho etsa hore li tšoanelehe bakeng sa likopo moo ho boloka mebala ho leng bohlokoa. Li-stabilizers li boetse li sireletsa phala ea PVC ka katleho ho senyeha nakong ea ts'ebetso le ho pepeseha ka ntle.
Li-stabilizers tse thehiloeng ho calcium, tse kang calcium stearate le calcium zinc stabilizers, ke mekhoa e meng e se nang chefo ho e-na le li-stabilizers tse thehiloeng ho loto 'me hangata li sebelisoa ha ho etsoa lipeipi tsa PVC bakeng sa metsi a nooang le ho paka lijo. Li-stabilizer tsena li na le botsitso bo botle ba mocheso le ho hanyetsa boemo ba leholimo, ho etsa hore li tšoanelehe bakeng sa lits'ebetso tsa kantle.
Li-stabilizers tsa tlhaho, tse kang oli ea soya ea epoxidized le methyltin mercaptide, li tsoa mehloling ea tlhaho 'me li tumme ka lebaka la thepa ea tsona ea tikoloho le e se nang chefo. Li-stabilizers tsena li sireletsa ka katleho liphaephe tsa PVC ho senyeha ha mocheso 'me li loketse likopo tse nang le melao e thata ea tikoloho.
Nakong ea ts'ebetso ea ho etsa liphaephe tsa PVC, li-stabilizer tsa mocheso oa PVC li kenngoa ho resin ea PVC nakong ea ts'ebetso ea ho kopanya ho etsa motsoako oa homogeneous. Li-stabilizers li thibela ka katleho liketso tsa ho senyeha tse bakoang ke mocheso le khanya ka ho etsa li-complexes tse nang le liketane tsa PVC polymer. Sena se etsa bonnete ba hore phala ea PVC e boloka matla a eona a mochine, botsitso ba mebala le botšepehi ba likarolo ho pholletsa le bophelo ba eona ba tšebeletso.
Nakong ea bophelo ba liphaephe tsa PVC, ho pepesehela lintho tse ka ntle tse kang khanya ea letsatsi, ho fetoha ha mocheso, lik'hemik'hale, joalo-joalo ho tla potlakisa ho senyeha ha thepa ea PVC. Li-stabilizer tsa mocheso oa PVC li phetha karolo ea bohlokoa ho sireletsa liphaephe ho tloha linthong tsena tse senyang, ho netefatsa hore li sebetsa ka nako e telele le ho tšepahala.
Tšebeliso ea li-stabilizer tsa mocheso oa PVC ke ea bohlokoa ho boloka boleng le ts'ebetso ea liphaephe tsa PVC. Li-stabilizers tsena li sireletsa thepa ea PVC ho senyeha ha mocheso le ho etsa bonnete ba hore phala e boloka thepa ea eona ea mechine, botsitso ba mebala le botšepehi ba mahlakore. Ha theknoloji ea stabilizer e ntse e tsoela pele, hona joale ho na le likhetho tse fapaneng tsa ho fihlela litlhoko tse ikhethang tsa lits'ebetso tse fapaneng tsa liphaephe tsa PVC. Ha tlhokahalo ea liphaephe tsa PVC tsa boleng bo phahameng le tse tšoarellang li ntse li hōla, bohlokoa ba li-stabilizer tsa mocheso oa PVC indastering ea liphaephe tsa PVC bo ke ke ba fetisoa.
