Libaka tsa Ts'ebeliso tsa TPU

Ka 1958, Goodrich Chemical Company e United States e ile ea ngolisa ka lekhetlo la peleSehlahisoa sa TPULetšoao la Estane. Lilemong tse 40 tse fetileng, lihlahisoa tse fetang 20 tsa lihlahisoa li hlahile lefatšeng ka bophara, e 'ngoe le e 'ngoe e na le letoto la lihlahisoa tse 'maloa. Hona joale, bahlahisi ba ka sehloohong ba lefats'e ba thepa e tala ea TPU ba kenyelletsa BASF, Covestro, Lubrizol, Huntsman, Macintosh, Gaoding, jj.
Jwalo ka elastomer e sebetsang hantle, TPU e na le mefuta e mengata ya ditataiso tsa dihlahiswa tse latelang mme e sebediswa haholo dibakeng tsa bohlokwa tsa letsatsi le letsatsi, thepa ya dipapadi, dibapadi, thepa ya mekhabiso le mafapha a mang. Ka tlase ke mehlala e mmalwa.
①Thepa ea lieta
TPU e sebelisoa haholo bakeng sa thepa ea lieta ka lebaka la ho tenyetseha ha eona ho hoholo le ho hanyetsa ho tsofala. Lihlahisoa tsa lieta tse nang le TPU li phutholoha haholo ho li apara ho feta lihlahisoa tse tloaelehileng tsa lieta, kahoo li sebelisoa haholo lihlahisoa tsa lieta tsa maemo a holimo, haholo-holo lieta tse ling tsa lipapali le lieta tse tloaelehileng.
② Liphaephe
Ka lebaka la bonolo ba eona, matla a ho thapolla a matle, matla a ho thulana, le ho hanyetsa mocheso o phahameng le o tlase, liphaephe tsa TPU li sebelisoa haholo Chaena e le liphaephe tsa khase le oli bakeng sa lisebelisoa tsa mechini tse kang lifofane, litanka, likoloi, lithuthuthu le lisebelisoa tsa mechini.
③ Thapo
TPU e fana ka ho hanyetsa meokho, ho hanyetsa ho tsofala, le litšobotsi tsa ho kobeha, 'me ho hanyetsa mocheso o phahameng le o tlase e le senotlolo sa ts'ebetso ea cable. Kahoo 'marakeng oa Chaena, likhoele tse tsoetseng pele joalo ka likhoele tsa taolo le likhoele tsa motlakase li sebelisa TPU ho sireletsa thepa ea ho roala ea likhoele tse rarahaneng tse entsoeng,' me lits'ebetso tsa tsona li ntse li ata haholo.
④ Lisebelisoa tsa bongaka
TPU ke thepa e bolokehileng, e tsitsitseng, le e boleng bo holimo e nkang sebaka sa PVC e se nang lik'hemik'hale tse kotsi tse kang li-phthalates, tse ka fetelang maling kapa maro a mang ka har'a li-catheter tsa bongaka kapa mekotla 'me tsa baka litla-morao. Hape ke TPU e ntlafalitsoeng ka ho khetheha ea sehlopha sa extrusion le sehlopha sa ente e ka sebelisoang habonolo ka liphetoho tse nyane lisebelisoa tse teng tsa PVC.
⑤ Likoloi le mekhoa e meng ea lipalangoang
Ka ho ntša le ho maneha mahlakore ka bobeli a lesela la nylon ka polyurethane thermoplastic elastomer, ho ka etsoa li-raft tsa tlhaselo ea ntoa tse ka buloang le li-raft tsa tlhahlobo tse jereng batho ba 3-15, 'me ts'ebetso ea tsona e phahametse haholo ho feta ea li-raft tsa rabara tse buloang; Li-elastomer tsa polyurethane thermoplastic tse matlafalitsoeng ka fiberglass li ka sebelisoa ho etsa likarolo tsa 'mele tse kang likarolo tse bōpiloeng mahlakoreng ka bobeli a koloi ka boeona, matlalo a mamati, li-bumper, li-strips tse thibelang khohlano le li-grille.
