Thermoplastic polyurethane feem ntau abbreviated li TPU. Nws yog cov txheej txheem thermoplastic elastomer yaj. Nws muaj cov yam ntxwv ntawm ob qho tib si yas thiab roj hmab. Yog li, nws nthuav tawm cov khoom zoo li durability, yoog raws, thiab lub zog tensile zoo heev. Nws ua tiav cov kev xav tau ntawm ntau daim ntawv thov xav tau. Cov no suav nrog tsheb, xov hlau thiab cables, kev ua kis las, thiab textile coatings.
TPU yog cov khoom siv xaiv hauv cov ntawv thov uas muaj kev cuam tshuam tsis zoo yog qhov tseem ceeb. Cov no suav nrog cov khoom siv hauv tsheb, kev ua kis las thiab kev lom zem, cov khoom siv hluav taws xob, thiab cov khoom tshwj xeeb cables. Nws qhia tau zoo heev thaum piv rau lwm cov ntaub ntawv thermoplastic.
Qhov zoo
TPU yog cov khoom siv xaiv hauv cov ntawv thov uas muaj kev cuam tshuam tsis zoo yog qhov tseem ceeb. Cov no suav nrog cov khoom siv hauv tsheb, kev ua kis las thiab kev lom zem, cov khoom siv hluav taws xob, thiab cov khoom tshwj xeeb cables. Nws qhia tau zoo heev thaum piv rau lwm cov ntaub ntawv thermoplastic.
Kev puas tsuaj ntawm cov ntaub ntawv feem ntau yog txiav txim siab los ntawm kev ntsuas qhov hnyav ntawm cov qauv hauv cov qauv coj los kuaj. Qhov no yog qhia hauv daim duab hauv qab no:
Ua pa TPU ua kom zoo tshaj plaws
Kev nplij siab yog qhov tseem ceeb tshaj plaws thaum koj tsim cov khaub ncaws ncaws pob lossis cov khoom siv hauv tsev thiab kev tsim kho. TPUs ua pa zoo heev muaj los ua kom muaj kev nplij siab zoo.
Ib txwm TPU muaj vapor kis hauv qab 1,500 g / m2 / hnub. Txawm hais tias cov qib ua pa muaj txiaj ntsig muaj txiaj ntsig siab txog 10, 000 g / m2 / hnub (+560%). Tsoos TPUs tuaj yeem muab sib xyaw nrog cov pa ua pa. Qhov no zoo-tunes lub breathability raws li koj daim ntawv thov yuav tsum tau.
Polyester, Polyether thiab Polycaprolactone yog peb hom tshuaj tseem ceeb ntawm TPU granules.
BQ4198 yog Polyester TPU uas yog tsim los ntawm polyols uas muaj ester pawg. Lub TPU no muaj cov khoom siv zoo tshaj plaws, suav nrog kev ua haujlwm tsis zoo, tshuaj lom neeg ua haujlwm, lub zog tensile, kev ua haujlwm zoo, Moulding ceev, Yooj yim demolded, Zoo heev abrasive kuj.
