TPU (Thermoplastic Polyurethane)siv rau hauv kev tsim cov dej tsis pub dhau ntau yam, suav nrog cov ntaub thaiv dej tsis pub dhau, cov ntawv tiv thaiv dej, cov yeeb yaj kiab nplaum kub yaj, thiab cov txheej txheej, kom tau raws li qhov xav tau ntawm kev tiv thaiv dej, tiv thaiv dej noo, thiab kev kaw ntawm ntau qhov xwm txheej sib txawv.
√ Cov Ntawv Thov Tseem Ceeb thiab Piv Txwv
- Cov Ntawv Tiv Thaiv Dej / Cov Ntawv Txheej Txheem: Siv ua cov txheej tiv thaiv dej ua haujlwm siab rau cov haujlwm loj xws li ru tsev, qab nthab, qhov av, choj, thiab cov pas dej.
- Cov Ntawv Uas Ua Pa Tau Dej: Cia cov pa dej tawm thaum thaiv cov dej kua sab nraud nkag mus - tsim nyog rau sab nraud ntawm cov txheej rwb thaiv tsev kom txhim kho kev nyab xeeb ntawm lub tsev, siv rau phab ntsa, ru tsev, thiab cov qauv ntoo.
- Cov Khoom Siv Kaw Dej Tsis Tau: Siv rau cov pob qij txha, ntug laj kab, cov hauv paus yeeb nkab thiab lwm yam ntsiab lus, lossis ua cov khoom kaw dej uas o tuaj yeem rau kev nthuav dav thiab kev tsim kho.
- Cov Tshuaj Pleev Xim Tiv Thaiv Dej: Siv ua ib txheej rau ntawm cov pob zeb, hlau, thiab lwm yam khoom siv los ua ib daim zaj duab xis tiv thaiv dej tsis muaj qhov tsis sib xws - tsim nyog rau cov pas dej ua ke, cov plag tsev lag luam, thiab lwm yam.
- Iav Kev Nyab Xeeb Laminated: Zaj duab xis TPU muaj zog, tawv khov kho khi cov iav tawg kom tiv thaiv kev tawg - siv rau hauv cov phab ntsa ntaub thaiv qhov rais thiab lub qhov rais saum ru tsev.
√ Cov Txheej Txheem Kev Siv thiab Kev Ua Haujlwm
- Cov Khoom Siv Lub Cev/Khoom Siv Kho Tshuab:
Lub zog tensile ntawm cov ntawv tsis muaj dej feem ntau yog 30–45 MPa, elongation thaum tawg 500–700%, tuab 0.2–0.5 hli.
Cov ntaub TPU sib xyaw ua ke muaj qhov tiv taus qhov tho ≥80 N / mm² thiab elongation thaum tawg ≥300%. - Kev Ruaj Ntseg thiab Kev Ruaj Ntseg:
Qhov kub yaj kwv yees li 90°C, qhov kub hloov pauv cua sov 70–90°C.
Tom qab 500 teev ntawm kev laus cua sov ntawm 80 ° C, lub zog tensile poob <5%.
Kev ua haujlwm ruaj khov ntawm -40 ° C; qee qib siv tau txog li -65 ° C. - Ib puag ncig & Kev Nyab Xeeb:
TPU tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab zoo rau ib puag ncig.
100% cov hmoov khov kho tsis muaj VOC emissions, ua tau raws li cov kev cai tsim kho ntsuab.
√ Kev Tsim Kho thiab Siv Cov Ntsiab Lus
- Kev Siv Sib Xyaws: Piv txwv li, kev sib xyaw 69.2% TPU, 30% hmoov roj hmab, thiab 0.8% defoamer tuaj yeem tsim cov khoom siv tiv thaiv dej uas tsim nyog rau cov txheej txheem tiv thaiv dej ntawm txoj kev tsheb ciav hlau ceev ceev.
- Kev Xaiv Txheej Txheem:
- TPU hmoov: txheej txheej tawg + nias kub
- TPU kub yaj zaj duab xis: high-zaus lossis ultrasonic vuam
- Daim ntawv TPU: cua kub vuam lossis cov nplaum tshwj xeeb rau kev sib tshooj
- Kev Ruaj Ntseg Kub yog Qhov Tseem Ceeb: Kev tiv thaiv dej yog qhov tseem ceeb rau kev tiv thaiv dej ntawm lub tsev. Qee cov qauv TPU lwj ntau heev hauv dej kub ntev; qhov av noo ntev ntev tuaj yeem ua rau hydrolysis ua rau lub foob tsis ua haujlwm. Yog li ntawd, kev xaiv qib hydrolysis-resistant yog qhov tseem ceeb heev.
- Kev Kho Kom Zoo Nkauj Yog Qhov Tseem Ceeb: Ntawm cov khoom siv uas muaj qhov dej lossis du, kev siv cov primer sib xws ua rau kev sib txuas ntawm TPU txheej thiab cov khoom siv zoo dua, ua kom ntseeg tau tias cov txheej tiv dej tsis nkag mus tau zoo.
- Rau cov kev siv dej tsis pub dhau ntawm lub tsev,TPU raws li polyetherua los ntawmYantai Linghua cov khoom tshiabfeem ntau yog qhov kev xaiv zoo dua vim tias nws cov ether bonds (-COC-) muaj zog tiv taus hydrolysis thiab zoo dua rau cov chaw ntub dej ntev.
