1, kenyelletso ea filimi ea polyester

Filimi ea polyester e boetse e bitsoa filimi ea polyester (PET) (filimi e khanyang, filimi ea polyester, pampiri e bonolo, filimi ea polyester, filimi ea benzene tin, cellophane, filimi e lokollang), ke polyethylene terephthalate e le lisebelisoa tse tala, tšebeliso ea mokhoa oa extrusion filiming e teteaneng, ebe ho otlolla mahlakore ka bobeli ho entsoe ka thepa ea lifilimi.

Filimi ea lapeng ea polyester (filimi ea polyester, filimi ea ts'ireletso ea tikoloho, filimi ea PET, filimi ea opal le lisebelisoa tse ling tsa khatiso le ho paka), e sebelisoang haholo indastering ea polasetiki e matlafalitsoeng ea khalase, indasteri ea thepa ea kaho, indasteri ea khatiso, meriana le bophelo bo botle.

Hona joale, Chaena e atlehile ho hlahisa filimi ea PET twist, e se nang chefo, e se nang mebala, e bonaletsang, e thibelang mongobo, e phefumolohang, e bonolo, e matla, e nang le mafura a acid-alkali le e thibelang ho qhibiliha, 'me e sa tšabe mocheso o phahameng le o tlaase.Ke ntho e se nang chefo, e pepeneneng e ka sebelisoang hape ka har'a lino tse fapaneng, metsi a liminerale le liphutheloana tsa lifilimi, hajoale e sebelisoa haholo lefats'eng e le e 'ngoe ea lisebelisoa tsa ho paka.

Filimi ea Mylar ke mofuta oa filimi ea polasetiki ea polymer, ka lebaka la thepa ea eona e phethahetseng e felletseng ebile e ratoa le ho feta ke bareki ba bangata.Kaha boemo ba tlhahiso ea China le botekgeniki bo ntse bo sa khone ho fihlela litlhoko tsa 'maraka, ba bang ba ntse ba hloka ho itšetleha ka thepa e tsoang kantle ho naha.

2, thepa ea filimi ea polyester

PET ke polymer e phahameng, e bakoang ke ho fokotseha ha metsi 'meleng oa ethylene terephthalate.Glycol terephthalate e fumanoa ka esterification ea terephthalic acid le glycol.PET ke 'mala o mosoeu kapa o mosehla o khanyang, o khanyang haholo o nang le bokaholimo bo boreleli, bo benyang.

PET e na le thepa e ntle haholo (ho hanyetsa mocheso, ho hanyetsa lik'hemik'hale).Matla le ho tiea, ho kenya motlakase, polokeho, joalo-joalo), theko e tlaase, e sebelisoang haholo e le fiber, filimi, polasetiki ea boenjiniere, libotlolo tsa polyester joalo-joalo.

PET e na le thepa e ntle ea 'mele le ea mochini maemong a mocheso o pharalletseng, mocheso oa tšebeliso ea nako e telele ho fihla ho 120 ℃, insulation e ntle ea motlakase, leha e le mocheso o phahameng le maqhubu a phahameng, thepa ea eona ea motlakase e ntse e le ntle, empa e fokola ea corona, anti-toxic. , ho hanyetsa boemo ba leholimo, botsitso ba lik'hemik'hale, ho phalla, ho hanyetsa mokhathala, ho hanyetsa likhohlano, botsitso ba dimensional li ntle haholo.Ho monya metsi a tlase, ho hanyetsa li-acid tse fokolang le li-solvents tsa organic, empa eseng mocheso o hananang le ho qoelisoa, eseng ho hanyetsa alkali.

Hangata PET ha e na 'mala e pepeneneng, filimi e benyang (likaroloana tse tlatselitsoeng joale li ka eketsoa ho etsa hore e be le mebala), thepa e ntle ea mochini, ho tiea ho hoholo, ho thatafala le ho tiea, ho hanyetsa ho phunya, ho hanyetsa likhohlano, mocheso o phahameng le ho hanyetsa mocheso o tlase, ho hanyetsa lik'hemik'hale, oli. ho hanyetsa, ho tiisa moea le ho boloka monko o monate, ke e 'ngoe ea li-substrates tsa filimi tse hanyetsanang le ho phunyeletsa tse sebelisoang hangata, empa khanyetso ea corona ha e ntle.
