Plastiki ea PVC e bua ka PVC e kopaneng indastering ea lik'hemik'hale.Lebitso la Senyesemane: polyvinyl chloride, khutsufatso ea Senyesemane: PVC.Ena ke moelelo o sebelisoang haholo oa PVC.
'Mala oa eona oa tlhaho o mosehla o khanyang le o khanyang.Ponahalo e ntle ho feta ea polyethylene le polypropylene, 'me e mpe ho feta ea polystyrene.Ho itšetlehile ka palo ea li-additives, e ka aroloa ka PVC e bonolo le e thata.Lihlahisoa tse bonolo li bonolo ebile li thata, 'me li ikutloa li khomarela.Boima ba lihlahisoa tse thata bo phahame ho feta ba polyethylene e tlaase, empa e tlaase ho feta ea polypropylene, 'me ho tla ba le albinism ho likobe.Lihlahisoa tse tloaelehileng: lipoleiti, liphaephe, li-soles, lipapali, mamati le lifensetere, matlalo a terata, lintho tsa ho ngola, joalo-joalo Ke mofuta oa thepa ea polymer e sebelisang athomo ea chlorine ho nkela athomo ea hydrogen ka polyethylene.
Semathi le heke: liheke tsohle tse tloaelehileng li ka sebelisoa.Haeba o sebetsana le likarolo tse nyane, ho molemo ho sebelisa heke ea mofuta oa nale kapa heke e ka tlas'a metsi;Bakeng sa likarolo tse teteaneng, ho molemo ho sebelisa liheke tse nang le sebōpeho sa fan.Bophara bo fokolang ba heke ea mofuta oa nale kapa heke e ka tlas'a metsi e tla ba 1mm;Botenya ba heke e nang le sebopeho sa fan ha boa lokela ho ba ka tlase ho 1mm.
Ts'ebeliso e tloaelehileng: lipeipi tsa phepelo ea metsi, lipeipi tsa ntlo, mabota a ntlo, likhetla tsa mochini oa khoebo, ho paka lihlahisoa tsa elektroniki, lisebelisoa tsa bongaka, ho paka lijo, jj.
Lik'hemik'hale le thepa ea 'mele ea PVC e thata ea PVC ke e' ngoe ea lisebelisoa tsa polasetiki tse sebelisoang ka ho fetisisa.Lisebelisoa tsa PVC ke thepa ea amorphous.Li-stabilizers, lubricant, li-agent tse thusang, li-pigment, li-reinforcing agents le li-additives tse ling hangata li kenngoa ho thepa ea PVC ka tšebeliso e sebetsang.
Lisebelisoa tsa PVC ha li na ho cha, matla a phahameng, ho hanyetsa boemo ba leholimo le botsitso bo botle ba geometri.PVC e na le khanyetso e matla ho li-oxidants, li-reductants le li-acid tse matla.Leha ho le joalo, e ka corroded ke concentrated oxidizing acids tse kang concentrated sulfuric acid le concentrated nitric acid, 'me ha e ea lokela liketsahalong tsa ho kopana le li-hydrocarbon tse nkhang hamonate le li-hydrocarbon tse chlorinated.
Mocheso o qhibilihang oa PVC nakong ea ts'ebetso ke parameter ea bohlokoa haholo ea ts'ebetso.Haeba parameter ena e sa lokela, e tla lebisa bothateng ba ho senyeha ha thepa.Litšobotsi tsa phallo ea PVC li fokola haholo, 'me mefuta ea eona ea ts'ebetso e moqotetsane haholo.Haholo-holo, lisebelisoa tsa PVC tse nang le boima bo boholo ba limolek'hule li thata haholo ho sebetsa (thepa ena hangata e hloka ho eketsa lubricant ho ntlafatsa litšobotsi tsa phallo), kahoo lisebelisoa tsa PVC tse nang le boima ba limolek'hule tse nyenyane li atisa ho sebelisoa.Ho honyela ha PVC ho tlase haholo, ka kakaretso ke 0.2 ~ 0.6%.
