I-Thermoplastic polyurethane (TPU) yisigaba esiyingqayizivele sepulasitiki esidalwe lapho ukusabela kwe-polyadition kwenzeka phakathi kwe-disocyanate ne-diol eyodwa noma ngaphezulu. Yaqala ukuthuthukiswa ngo-1937, le polymer esebenza ngezindlela eziningi ithambile futhi iyacutshungulwa uma ishiswa, iqinile uma ipholile futhi iyakwazi ukucutshungulwa kaningi ngaphandle kokulahlekelwa ubuqotho besakhiwo. Isetshenziswa njengepulasitiki yobunjiniyela obuthambile noma esikhundleni senjoloba eqinile, i-TPU idume ngezinto eziningi okuhlanganisa: ubude obuphezulu namandla aqinile; nokunwebeka kwayo; futhi ngamazinga ahlukahlukene, ikhono layo lokumelana nowoyela, amafutha, izinyibilikisi, amakhemikhali kanye nokuhuzuka. Lezi zici zenza i-TPU idume kakhulu kuzo zonke izimakethe nezinhlelo zokusebenza. Ivumelana nezimo ngokwemvelo, inganwetshwa noma ibunjwe ngomjovo emshinini ojwayelekile wokukhiqiza we-thermoplastic ukuze yakhe izingxenye eziqinile ngokuvamile zezicathulo, ikhebula nocingo, ipayipi neshubhu, ifilimu neshidi noma eminye imikhiqizo yemboni. Ingase futhi ihlanganiswe ukuze idale ama-moldings epulasitiki aqinile noma acutshungulwe kusetshenziswa ama-solvents e-organic ukuze enze izindwangu ze-laminated, izigqoko zokuzivikela noma izinamathiselo ezisebenzayo.
Iyini i-Waterproof TPU Indwangu?
Indwangu ye-TPU engangeni manzi iwulwelwesi lwe-bi - layer i-TPU ecubungula izici ezisebenzayo.
Kufaka phakathi amandla aphezulu okudabula, ukungenwa kwamanzi, nokudluliswa komswakama ophansi. Idizayinelwe inqubo ye-lamination yendwangu. Yaziwa ngokungaguquguquki kwayo, ikhipha ikhwalithi ephezulu kakhulu, ethembeke kakhulu i-thermoplastic polyurethane (TPU) namafilimu aphefumulayo angangeni manzi e-copolyester embonini. Amafilimu neshidi elisekelwe ezintweni ezihlukahlukene futhi eliqinile le-TPU asetshenziselwa ukubopha indwangu, ukuvimbela amanzi, kanye nezinhlelo zokusebenza zokufaka umoya noma uketshezi. Amafilimu neshidi le-TPU elizacile kakhulu nelinama-hydrophilic afaneleka ngokufanelekile ukufakwa ezindwangu. Abaqambi bangakha izindleko - izinhlanganisela zendwangu eziphefumulayo ezingangeni manzi efilimini eyodwa - ukuya ku-lamination yendwangu. Okubalulekile kunikeza ukuphefumula okuvelele kokunethezeka komsebenzisi. Amafilimu endwangu yokuzivikela kanye neshidi engeza ukubhoboza, ukuhuzuka, nokumelana namakhemikhali ezindwangu eziboshelwe kuzo.
