Sekhomaretsi sa PVC ke sekhomaretsi se etselitsoeng ka ho khetheha ho kopanya thepa ea polyvinyl chloride (PVC), se fanang ka matla a matle a tlamo, ho hanyetsa boemo ba leholimo le botsitso ba lik'hemik'hale. Moetso oa eona o its'etleha haholo-holo holim'a{{1}sistimi e thehiloeng ho solvent, e netefatsang ho koloba le ho khomarela karolo e nyenyane ea PVC ka ho khetha polymer, plasticizer, le solvent e nepahetseng.
Likarolo tsa mantlha tsa sekhomaretsi sa PVC hangata li kenyelletsa vinyl chloride-vinyl acetate copolymer (PVAc), polyvinyl chloride resin (PVC resin), le plasticizer (joalo ka dioctyl phthalate (DOP)). Ts'ebetso ea ho kopanya pele e kenyelletsa ho qhaqha resin ea PVC ka har'a motsoako oa tlhaho. Li-solvents tse tloaelehileng li kenyelletsa cyclohexanone, toluene, le dichloromethane. Li-solvents tsena ka katleho li nolofatsa liketane tsa limolek'hule tsa PVC, li matlafatsa metsi le ho ntlafatsa thepa ea tlamahano.
Nakong ea ts'ebetso ea ho kopanya, PVAc kapa li-polymer tse ling tsa thermoplastic li sebelisoa e le karolo ea mantlha ea tlamahano. Li-polymer tsena li bonts'a tšebelisano e ntle haholo le resin ea PVC, li theha maqhama a matla kamora hore mokelikeli o fetohe mouoane. Ho eketsoa ha polasetiki ho ntlafatsa ho tenyetseha ha sekhomaretsi le matla a tlamo, ho thibela ho phatloha ho bakoang ke ho tiea ho feteletseng ha thepa ea PVC. Ho feta moo, likhomaretsi tse ling tsa PVC li boetse li na le li-stabilizers (tse kang calcium-zinc stabilizers) ho ntlafatsa ho hanyetsa mocheso le ho thibela ho tsofala.
Ts'ebetso ea ho kopanya hangata e sebelisa polymerization ea tharollo kapa ho kopanya 'mele. Ho polymerization ea tharollo, li-monomers li entsoe ka polymerized ka har'a sopho ho etsa polima e kopanyang, e ntan'o kopanngoa le polasetiki le mokelikeli. Ka ho kopanya 'mele, resin ea PVC e entsoeng esale pele, polyvinyl acetate (PVAc), le plasticizer li tsoakoa ka ho lekana 'me li qhalakanngoa ka mokhoa o ts'oanang ho sebelisoa{2}}ho sisinyeha ha lebelo.
Qetellong, sekhomaretsi sa PVC se entsoeng ka maiketsetso se tlhotliloeng le ho tlosoa ho etsa bonnete ba hore ha ho na litšila tse itseng kapa li-bubble tse ka amang phello ea tlamahano. Sekhomaretsi sena se sebelisoa haholo ho kopanya liphaephe tsa PVC, maqephe, lifilimi le lisebelisoa tse ling, 'me se na le ho phekola ka potlako, litlamo tse matla, le ho hanyetsa metsi le oli. Ka ho ntlafatsa ts'ebetso ea ho theha le ho kopanya, ts'ebetso ea eona e ka ntlafatsoa le ho feta ho fihlela litlhoko tsa lits'ebetso tse fapaneng tsa indasteri.
