6. Hydrophobic: UHMWPE fiber ntau yog hydrophobic, uas txhais tau hais tias nws tsis nqus dej lossis noo noo. Cov cuab yeej no ua rau nws tsim nyog rau kev siv sab nraum zoov uas muaj av noo lossis ntub dej.
7. Tsawg Thermal Conductivity: UHMWPE fiber ntau muaj thermal conductivity tsawg, uas txhais tau tias nws tsis ua cua sov zoo. Cov cuab yeej no ua rau nws zoo heev rau kev siv kub-kub qhov chaw rwb thaiv tsev tsim nyog.
Kev siv ntawm UHMWPE Fiber:
1. Kev Tiv Thaiv Ballistic: UHMWPE fiber ntau yog siv rau hauv kev tsim cov khoom tiv thaiv ballistic xws li lub cev armor thiab kaus mom hlau vim nws lub zog siab-rau-hnyav piv thiab muaj kev cuam tshuam tshwj xeeb.
2. Muaj Ropes: UHMWPE fiber ntau kuj tseem siv rau hauv kev tsim cov hlua kev ruaj ntseg, kab thiab cables vim nws lub siab tawv thiab muaj peev xwm tiv taus siab loads.
3. Cov kab nuv ntses: UHMWPE fiber ntau yog siv los ua cov kab nuv ntses thiab cov nets vim nws cov dej tsis haum, lub zog siab, thiab kev puas tsuaj.
4. Aerospace: UHMWPE fiber ntau yog siv rau hauv kev lag luam aerospace rau kev tsim kho cov khoom siv dav hlau xws li kev tswj cov kab hluav taws xob, thiab cov kab nres vim nws lub zog siab thiab tiv thaiv kev puas tsuaj.
5. Cov Khoom Siv Kho Mob: UHMWPE fiber ntau yog siv rau hauv kev tsim cov khoom siv kho mob thiab cov cuab yeej siv vim nws cov biocompatibility siab, tsis muaj zog, thiab lub zog siab.
Kev xav tau rau UHMWPE Fiber:
1. Zoo: UHMWPE fiber ntau yuav tsum zoo thiab ua tau raws li cov qauv nruj kom ntseeg tau tias nws cov khoom siv tau raws li qhov yuav tsum tau ua.
2. Kev Ua Haujlwm: UHMWPE fiber ntau yuav tsum muaj cov txheej txheem tshwj xeeb los xyuas kom cov fibers tsis degraded thaum lub sijhawm tsim khoom, uas tuaj yeem cuam tshuam rau lawv cov khoom siv kho tshuab.
3. Cia: UHMWPE fiber ntau yuav tsum tau khaws cia kom zoo kom tsis txhob raug kub hnyiab, UV hluav taws xob, thiab noo noo, uas tuaj yeem cuam tshuam cov khoom fiber ntau.
4. Kev Ntsuas: UHMWPE fiber ntau yuav tsum tau kuaj xyuas nruj kom ntseeg tau tias nws cov khoom siv dag zog xws li tensile zog, elongation, thiab modulus nyob rau hauv qhov yuav tsum tau muaj.
