Kenyelletso ea Thepa ea Plastiki ea PVC le Mebala e Tloaelehileng

E itšetlehile ka thepa e tsotehang ea polasetiki ea PVC, hona joale e sebelisoa libakeng tse ngata tsa bophelo. 'Me maqephe ana a PVC, ka kakaretso ke lihlahisoa tse entsoeng. E eketsa li-colorants tse itseng ts'ebetsong ea tlhahiso ho etsa hore lihlahisoa li be ntle le ho feta. Empa batho ba bang ha ba tsebe haholo ka sena, kajeno sehlooho sena se tla hlahisa ka ho qaqileng.

Resin ea PVC ke thermoplastic e nang le meaho e sa hlalosoang. Sebaka se nolofatsang sa resin se haufi le mocheso oa ho bola. E se e qalile ho bola ho 140 ℃, mme le ho feta ka potlako ho 170 ℃. Ka lebaka la likahare tsa eona tsa liathomo tsa chloride, molek'hule ea polyethylene le li-copolymers tsa eona hangata ha li na lelakabe ka lintho tse itimang le tse sa theoheng. Ke polymer e sa tsitsang ho feta e boetse e senngoa ke khanya le mocheso. E boetse e na le matla a matla a botsitso ba lik'hemik'hale, 'me e bohlokoa haholo joalo ka thepa ea anticorrosion. PVC e tsitsitse bakeng sa li-acid tse ngata tsa inorganic le metheo 'me e arotsoe bakeng sa hydrogen chloride.E ka qhibiliha ka li-ketone le li-solvents tse nkhang hamonate.

Mebala e sebelisoang bakeng sa lipolasetiki tsa PVC haholo-holo ke li-pigment tsa tlhaho le tsa tlhaho. Li-plastiki tsa PVC li na le litlhoko tse phahameng tsa li-pigment tse kang mocheso o phahameng oa ho hanyetsa nakong ea ts'ebetso, ha ho na ho falla ha ho sebetsa, ho hanyetsa khanya, joalo-joalo, mebala e tloaelehileng e sebelisoang ke: 1, khubelu ke haholo-holo qhibilihang ka har'a azo pigment, cadmium red inorganic pigment, iron oxide red pigment, phthalocyanine khubelu, joalo-joalo; 2, mosehla haholo-holo chromium mosehla, cadmium mosehla le fluorescent mosehla; 3, 'mala oa orchid haholo-holo phthalocyanine putsoa; 4, tala haholo-holo phthalocyanine tala; 5, tšoeu haholo-holo sebelisa titanium dioxide; 6, pherese haholo-holo ke polasetiki e pherese; 7, botšo haholo-holo ke carbon black. Ho phaella moo, sesebelisoa sa fluorescent whitening se sebelisetsoa ho soeufala; khauta le silevera phofo li sebelisetsoa ho hatisa mebala; le lifaha phofo astigmatism polasetiki joaloka perela.
