Mokotla oa polasetiki oa PVC
'Mala oa tlhaho o mosehla o khanyang le o khanyang.Ho pepeseha ho molemo ho feta polyethylene le polypropylene, empa ka tlase ho polystyrene.Ho itšetlehile ka palo ea li-additives, e ka aroloa ka polyvinyl chloride e bonolo le e thata.Lihlahisoa tse bonolo li na le ho fetoha ha maemo, ho thatafala le ho khomarela.Boima ba lihlahisoa tse thata ke tsa polyethylene e tlaase-tlaase, empa haeba e le tlase ho feta polypropylene, ho soeufala ho tla etsahala likotong.Lihlahisoa tse tloaelehileng: lipoleiti, liphaephe, li-soles, lipapali, mamati le lifensetere, li-sheath tsa terata, lintho tsa ho ngola, joalo-joalo Ke thepa ea polymer e sebelisang liathomo tsa chlorine ho e-na le liathomo tsa hydrogen ka polyethylene.
Lik'hemik'hale le Lintho Tsa 'Mele tsa PVC (Polyvinyl Chloride) PVC e thata ke e 'ngoe ea lisebelisoa tsa polasetiki tse sebelisoang haholo.Lisebelisoa tsa PVC ke thepa ea amorphous.Ts'ebelisong ea 'nete ea lisebelisoa tsa PVC, li-stabilizers, lubricant, kalafo tse thusang, li-pigments, li-imponsor le li-additives tse ling hangata lia eketsoa [2].
Lisebelisoa tsa PVC ha li chese, li matla, ha li na maemo a leholimo 'me li na le botsitso bo botle ba geometri.PVC e hanyetsana haholo le li-oxidizing agents, e fokotsang 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 ea lokela ho kopana le li-hydrocarbon tse nkhang hamonate kapa tse chlorine.
Mocheso o qhibilihang oa PVC nakong ea ts'ebetso ke parameter ea bohlokoa haholo ea ts'ebetso.Haeba parameter ena e sa tšoanelehe, mathata a ho senyeha ha thepa a tla etsahala.Thepa ea phallo ea PVC e futsanehile haholo mme mefuta ea eona ea ts'ebetso e moqotetsane haholo.Lisebelisoa tsa PVC tse boima ba limolek'hule li atisa ho sebelisoa, haholo-holo hobane lisebelisoa tsa PVC tse boima ba limolek'hule li thata ho sebetsa (mofuta ona oa thepa hangata o hloka ho eketsoa ha mafura ho ntlafatsa thepa ea phallo).Sekhahla sa shrinkage sa PVC se tlase haholo, ka kakaretso ke 0.2-0.6%.
