Global - Premier PET: Polymer e Phahameng bakeng sa Litšebeliso tse Fapaneng
Masimo a Maholo a Kopo
PET e sebelisoa haholo indastering ea ho paka, haholo-holo bakeng sa libotlolo tsa lino. Litšobotsi tsa eona tse ntle tsa thibelo khahlanong le oksijene, mongobo le carbon dioxide li etsa hore e be thepa e ntle bakeng sa ho boloka bocha le boleng ba lino tse nang le carbonate, lero le metsi. Ho pepeneneng ha PET ho lumella ponahalo e hlakileng ea sehlahisoa ka hare, ho ntlafatsa thekiso ea sona. Ho feta moo, libotlolo tsa PET li bobebe, li hanela ho robeha, 'me li bonolo ho li tšoara, e leng se etsang hore li be bonolo ho bareki. Liphuthelong tsa lijo, PET e sebelisetsoa lijana ho boloka lihlahisoa tse fapaneng tsa lijo, e fana ka tšireletso khahlanong le ho senyeha le ho boloka tatso le boleng ba lintho tse ka hare.
Indastering ea masela, PET ke thepa ea mantlha e tala bakeng sa ho hlahisa likhoele tsa maiketsetso. Likhoele tsena, tse tsejoang e le polyester, li na le matla a matle haholo, ho hanyetsa matheba le thepa ea ho omisa kapele. Li sebelisoa haholo tlhahisong ea liaparo, masela a lapeng le masela a indasteri. Likhoele tsa polyester tse thehiloeng ho PET li ka kopanngoa le likhoele tsa tlhaho ho ntlafatsa ho tšoarella le ts'ebetso ea lihlahisoa tsa ho qetela. Ho phaella moo, likhoele li ka dauoa habonolo, e leng se lumellang mebala le lipaterone tse fapaneng ho fihlela litlhoko tse fapaneng tsa feshene le moralo.
Indasteri ea lisebelisoa tsa elektroniki le eona e rua molemo ka thepa e ikhethang ea PET. E sebelisoa tlhahisong ea lifilimi le litheipi tse sireletsang mocheso ka lebaka la thepa ea eona e phahameng ea ho thibela mocheso ka motlakase. Lifilimi tsa PET li tšesaane, lia tenyetseha, 'me li na le botsitso bo botle ba litekanyo, e leng se etsang hore li lokele ho sebelisoa likarolong tse fapaneng tsa elektroniki tse kang li-capacitor, li-transformer le liboto tsa potoloho tse hatisitsoeng. Ho phaella moo, PET e sebelisoa tlhahisong ea li-screen tsa LCD e le thepa ea substrate, e fanang ka bokaholimo bo boreleli le bo tsitsitseng bakeng sa likarolo tsa ponts'o.
PET e boetse e sebelisoa indastering ea likoloi. E sebelisetsoa ho etsa likarolo tsa ho khabisa kahare, joalo ka liphanele tsa mamati le likoahelo tsa litulo, ka lebaka la litšobotsi tsa eona tse ntle tsa botle le ho hanyetsa ho tsofala le ho taboha. Metsoako e thehiloeng ho PET e sebelisoa tlhahisong ea likarolo tsa likoloi ho fokotsa boima le ho ntlafatsa ts'ebetso ea mafura. Ho feta moo, PET e sebelisoa tlhahisong ea likarolo tsa enjene le likarolo tsa sistimi ea mafura ka lebaka la ho hanyetsa mocheso le lik'hemik'hale.

Ka kakaretso
PET ea rona ea Global - Premier e fumaneha ka mefuta e fapaneng, ho kenyeletsoa li-pellet, lifilimi le likhoele, ho fihlela litlhoko tse ikhethileng tsa liindasteri tse fapaneng. Mofuta o mong le o mong oa PET o feta litekong tse matla tsa boleng ho netefatsa thepa e tsitsitseng, joalo ka viscosity, ntlha ea ho qhibiliha, matla a ho tensile le ho hlaka. Re fana ka litharollo tse ikhethileng ho fihlela litlhoko tse ikhethang tsa bareki ba rona. Ebang u k'hamphani ea ho paka Asia, moetsi oa masela Europe, k'hamphani ea lisebelisoa tsa elektroniki Amerika Leboea, kapa mofani oa likoloi Australia, PET ea rona ea Global - Premier ke polymer e tšepahalang le ea boleng bo holimo eo u ka e tšepang ho ntlafatsa ts'ebetso le boleng ba lihlahisoa tsa hau.
