Polyethylene ea Lefatše - ea Pele: Polymer e Feto-fetohang bakeng sa Mefuta e Mengata ea Litšebeliso

Masimo a Maholo a Kopo

Polyethylene e tumme ka ho hanyetsa lik'hemik'hale hantle haholo. E hanela lik'hemik'hale tse fapaneng haholo, ho kenyeletsoa li-acid, li-base le li-solvents. Thepa ena e etsa hore e be thepa e loketseng bakeng sa ts'ebeliso indastering ea lik'hemik'hale le meriana, moo e sebelisetsoang ho hlahisa lijana tsa polokelo, liphaephe le lisebelisoa tse ka sebetsanang ka mokhoa o sireletsehileng le lintho tse senyang. Ho se sebetse ha eona ka lik'hemik'hale ho boetse ho netefatsa hore ha e silafatse litaba tseo e li tšoereng, ho boloka bohloeki le botšepehi ba thepa e bolokiloeng.

Indastering ea ho paka, polyethylene e fumaneha hohle. Bongata ba eona bo tlase le ho tenyetseha ho hoholo ho e etsa hore e be e phethahetseng bakeng sa ho etsa lifilimi tsa ho paka tse bobebe le tse tšoarellang, mekotla le lijana. E fana ka thibelo e sebetsang khahlanong le mongobo, oksijene le mabaka a mang a tikoloho, e sireletsa lihlahisoa tse pakiloeng tšenyo le ho senyeha. Ebang ke bakeng sa ho paka lijo, moo e thusang ho boloka bocha le boleng ba lintho tse senyehang, kapa bakeng sa ho paka thepa ea bareki, moo e fanang ka tharollo e khahlang le e sebetsang ea ho paka, polyethylene e bapala karolo ea bohlokoa ho netefatseng polokeho le ho rekisoa ha lihlahisoa.

Indasteri ea kaho le eona e rua molemo o moholo ho polyethylene. E sebelisoa tlhahisong ea liphaephe bakeng sa litsamaiso tsa kabo ea metsi le khase. Liphaephe tsa polyethylene li tsebahala ka matla a tsona a phahameng, ho tšoarella, le ho hanyetsa ho khoptjoa le ho tetebela. Li na le bophelo bo bolelele ba tšebeletso 'me li hloka tlhokomelo e fokolang, e leng se etsang hore e be khetho e theko e tlaase bakeng sa merero ea meralo ea motheo. Ho feta moo, polyethylene e sebelisoa thepa ea ho thibela mocheso, e fanang ka thepa e ntle ea ho thibela mocheso e thusang ho fokotsa tšebeliso ea matla mehahong.

Indastering ea likoloi, polyethylene e sebelisoa lits'ebetsong tse fapaneng. E sebelisetsoa ho etsa likarolo tsa kahare tse kang li-dashboard, liphanele tsa mamati le likoahelo tsa litulo ka lebaka la bobebe ba eona, tlhaho ea eona e bonolo ea ho bopa le litšobotsi tse ntle tsa botle. E boetse e sebelisoa likarolong tsa kantle joalo ka li-bumper le li-fender, moo ho hanyetsa ha eona tšusumetso ho thusang ho ntlafatsa polokeho le ho tšoarella ha koloi. Ho feta moo, polyethylene e sebelisoa litankeng tsa mafura le mela ea mafura, ka lebaka la ho hanyetsa ha eona ho kenella ha mafura le botsitso ba lik'hemik'hale.

Polyethylene ea rona ea Global - Premier e fumaneha ka mekgahlelo le mefuta e fapaneng ho fihlela litlhoko tse ikhethileng tsa liindasteri tse fapaneng. Ebang ke polyethylene e nang le density e phahameng (HDPE) bakeng sa lits'ebetso tse hlokang matla a phahameng le ho tiea, kapa polyethylene e nang le density e tlase (LDPE) bakeng sa lits'ebetso tse tenyetsehang le tse otlolloang haholoanyane, re fana ka mefuta e mengata ea lihlahisoa. Sehlopha se seng le se seng se feta litekong tse matla tsa boleng ho netefatsa thepa e tsitsitseng, ho kenyeletsoa liteko tsa density, melting index, hardsile strength, le lelefalo. Polyethylene ea rona e pakiloe ka har'a thepa e loketseng ea ho paka ho e sireletsa nakong ea polokelo le lipalangoang. Ebang u k'hamphani ea ho paka Asia, feme ea kaho Europe, moetsi oa likoloi Amerika Leboea, kapa processor ea lik'hemik'hale Amerika Boroa, Polyethylene ea rona ea Global - Premier ke polymer e tšepahalang le e sebetsang hantle eo u e hlokang ho ntlafatsa boleng le ts'ebetso ea lihlahisoa tsa hau.
