I-Thermoplastic polyurethane (TPU) luhlobo olulodwa lweplastiki olwenziwe xa i-polyaddition reaction isenzeka phakathi kwe-disocyanate kunye ne-diol enye okanye ngaphezulu. Iqale yaphuhliswa ngo-1937, le polima ithambile kwaye iyaqhubekeka xa ishushubezwa, iqinile xa ipholile kwaye iyakwazi ukuphinda ihlaziywe kaninzi ngaphandle kokuphulukana nemfezeko yolwakhiwo. Isetyenziswa mhlawumbi njengeplastiki yobunjineli ethambileyo okanye ithathe indawo yerabha eqinileyo, iTPU idume ngezinto ezininzi eziquka: ubude obuphezulu kunye namandla okuqina; ukunwebeka kwayo; kunye namanqanaba ahlukeneyo, ukukwazi kwayo ukuxhathisa ioli, igrisi, izinyibilikisi, iikhemikhali kunye ne-abrasion. Ezi mpawu zenza i-TPU idume kakhulu kuluhlu lweemarike kunye nokusetyenziswa. Ngokwemvelo ibhetyebhetye, inokukhutshwa okanye ifakwe inaliti kwisixhobo sokwenza i-thermoplastic eqhelekileyo ukwenza izinto eziqinileyo ngokwesiqhelo kwizihlangu, intambo kunye nocingo, ithumbu kunye netyhubhu, ifilimu kunye neshiti okanye ezinye iimveliso zeshishini. Inokuphinda idityaniswe ukuze idale ukubunjwa kweplastiki eyomeleleyo okanye kusetyenzwe kusetyenziswa i-solvents ye-organic ukwenza i-laminated textiles, i-coatings yokukhusela okanye i-adhesives esebenzayo.
Yintoni ilaphu le-TPU elingangenwa ngamanzi?
Ilaphu le-TPU elingangenwa ngamanzi liyi-bi-maleko inwebu yi-TPU yokucubungula iimpawu ezininzi.
Bandakanya amandla aphezulu okukrazula, ukungangeni kwamanzi, kunye nokuhanjiswa kokufuma okuphantsi. Yenzelwe inkqubo yokulambisa ilaphu. Eyaziwayo ngokuhambelana kwayo, ikhupha umgangatho ophezulu kakhulu, i-thermoplastic polyurethane (TPU) ethembekileyo kunye ne-copolyester engenamanzi ifilimu ephefumulayo kwishishini. I-TPU eguquguqukayo kwaye ehlala ixesha elide - iifilimu kunye neshiti elisekelwe kwi-TPU lisetyenziselwa ukubopha ilaphu, ukuthintela amanzi, kunye nomoya okanye ukufakwa kwesiqulatho solwelo. Iifilimu zeTPU ezibhityileyo kakhulu kunye ne-hydrophilic kunye neshiti zifaneleke ngokufanelekileyo ukulahlwa kwamalaphu. Abaqulunqi banokudala iindleko - izixhobo ezilukiweyo eziphefumlayo ezisebenzayo kwifilimu enye - ukuya kwilaphu lamination. Izinto eziphathekayo zibonelela ngokuphefumla okubalaseleyo kokuthuthuzelwa komsebenzisi. Iifilimu ze-textile ezikhuselayo kunye neshiti zongeza i-puncture, i-abrasion, kunye nokuchasana kweekhemikhali kwiilaphu eziboshwe kuzo.
