Libaka tsa Kopo tsa TPU

Ka 1958, Goodrich Chemical Company e United States e ile ea ngolisa peleTPU sehlahisoamofuta oa Estane. Lilemong tse 40 tse fetileng, lihlahisoa tse fetang 20 li hlahile lefatšeng ka bophara, e 'ngoe le e 'ngoe e na le letoto la lihlahisoa tse ngata. Hajoale, baetsi ba mantlha ba lefats'e ba thepa e tala ea TPU ba kenyelletsa BASF, Covestro, Lubrizol, Huntsman, Macintosh, Gaoding, joalo-joalo.
Joaloka elastomer e sebetsang hantle, TPU e na le mefuta e mengata e fapaneng ea litaelo tsa lihlahisoa tse tlase 'me e sebelisoa haholo litlhoko tsa letsatsi le letsatsi, thepa ea lipapali, lintho tsa ho bapala, lisebelisoa tsa mekhabiso le likarolo tse ling. Ka tlaase ke mehlala e seng mekae.
①Lisebelisoa tsa lieta
TPU e sebelisoa haholo-holo bakeng sa lisebelisoa tsa lieta ka lebaka la elasticity ea eona e babatsehang le ho hanyetsa ho apara. Lihlahisoa tsa lieta tse nang le TPU li phutholohile ho feta lihlahisoa tsa lieta tse tloaelehileng, kahoo li sebelisoa haholo lihlahisoa tsa lieta tsa boemo bo phahameng, haholo-holo lieta tse ling tsa lipapali le lieta tse tloaelehileng.
② Hose
Ka lebaka la bonolo ba eona, matla a matle a ho tsitsa, matla a tšusumetso, le ho hanyetsa mocheso o phahameng le o tlaase, li-hose tsa TPU li sebelisoa haholo Chaena e le liphaephe tsa khase le oli bakeng sa lisebelisoa tsa mechine tse kang lifofane, litanka, likoloi, lithuthuthu le lisebelisoa tsa mochine.
③ Cable
TPU e fana ka khanyetso ea meokho, ho hanyetsa ho roala, le litšoaneleho tsa ho kobeha, ka ho hanyetsa mocheso o phahameng le o tlase e le senotlolo sa ts'ebetso ea cable. Kahoo 'marakeng oa Chaena, likhoele tse tsoetseng pele tse kang lithapo tsa taolo le likhoele tsa motlakase li sebelisa TPU ho sireletsa lisebelisoa tsa ho roala tsa likhoele tse rarahaneng tse entsoeng,' me lits'ebetso tsa bona li ntse li ata haholo.
④ Lisebelisoa tsa bongaka
TPU ke thepa e nkelang sebaka sa PVC e bolokehileng, e tsitsitseng le ea boleng bo holimo e se nang lik'hemik'hale tse kotsi tse kang phthalates, tse ka fallelang maling kapa lino tse ling ka har'a li-catheter kapa mekotla ea bongaka 'me tsa baka litla-morao. Hape ke sehlopha sa extrusion se ntlafalitsoeng ka mokhoa o ikhethileng le sehlopha sa ente sa TPU se ka sebelisoang habonolo ka litokiso tse nyane ho lisebelisoa tse teng tsa PVC.
⑤ Likoloi le mekhoa e meng ea lipalangoang
Ka ho ntša le ho roala mahlakoreng ka bobeli a lesela la nylon le polyurethane thermoplastic elastomer, lifofane tse hlaselang ntoa tse nang le inflatable le li-rafts tsa ho amohela batho ba 3-15 li ka etsoa, ​​​​'me ts'ebetso ea bona e phahame haholo ho feta ea rabara e nang le vulcanized rafts; Li-elastomer tsa polyurethane thermoplastic tse matlafalitsoeng ka fiberglass li ka sebelisoa ho etsa likarolo tsa 'mele tse kang likarolo tse bōpiloeng ka mahlakoreng a mabeli a koloi ka boeona, matlalo a mamati, li-bumpers, li-anti friction strips le li-grilles.
