Ultra-high molecular weight polyethylene fiber, tseem hu ua high-strength high-modulus polyethylene fiber, tam sim no yog cov fiber nrog lub zog tshwj xeeb tshaj plaws thiab cov qauv tshwj xeeb hauv ntiaj teb, thiab nws yog cov fiber ntau spun los ntawm polyethylene nrog lub cev hnyav ntawm 1 lab rau 5 lab.
kev ua tau zoo
1. Muaj lub zog tshwj xeeb thiab cov qauv tshwj xeeb siab. Lub zog tshwj xeeb yog ntau dua kaum npaug ntawm cov hlau hlau ntawm tib ntu ntu, thiab cov qauv tshwj xeeb yog thib ob nkaus xwb rau qib tshwj xeeb cov roj carbon fiber.
2. Cov fiber ntau tsawg, qhov ceev yog 0.97-0.98g/cm3, uas tuaj yeem ntab saum cov dej.
3. Tsawg elongation ntawm so, ua haujlwm zoo ntawm so, thiab muaj peev xwm muaj peev xwm nqus tau lub zog, yog li nws muaj qhov ua tau zoo tiv taus thiab txiav tsis kam.
4. Kev tiv thaiv hluav taws xob ultraviolet, tiv thaiv neutron thiab gamma rays, muaj lub zog nqus tshwj xeeb, tsis tshua muaj dielectric tsis tu ncua thiab muaj hluav taws xob sib kis tau zoo.
5. Tshuaj lom neeg tsis kam, hnav tsis kam, thiab ua haujlwm ntev lub neej.
Lub cev muaj zog:
Ceev: 0.97 ～ 0.98g/cm3. Nws muaj qhov ntom qis dua dej thiab tuaj yeem ntab saum dej.
Lub zog: 2.8 ～ 4N/tex.
Qauv: 91 ～ 140N/tex.
Kev nthuav dav: 3.5%～ 3.7%.
Qhov cuam tshuam nqus lub zog yog ze li ob zaug siab dua li ntawm para-aramid fiber. Nws muaj qhov ua tau zoo tiv taus thiab tsis sib txhuam coefficient, tab sis nws cov ntsiab lus melting tsuas yog 145-160 ℃ nyob rau hauv kev nyuaj siab.
siv:
Raws li UHMWPE fiber ntau muaj cov yam ntxwv zoo heev, nws tau qhia qhov zoo hauv kev ua lag luam muaj txiaj ntsig zoo, suav nrog los ntawm ntug dej hiav txwv roj av txuas hlua mus rau qhov ua tau zoo ntawm cov khoom sib xyaw ua ke, thiab tau qhia qhov zoo hauv kev ua tsov rog niaj hnub no thiab dav hlau. , Aerospace, khoom siv tiv thaiv kev tiv thaiv hiav txwv thiab lwm yam haujlwm ua lub luag haujlwm tseem ceeb
tiv thaiv teb chaws
Vim tias cov fiber muaj qhov ua tau zoo tiv taus thiab nqus tau lub zog ntau dua, nws tuaj yeem ua rau hauv kev tiv thaiv khaub ncaws, lub kaus mom hlau, thiab cov khoom siv tiv thaiv mos txwv hauv tub rog, xws li daim thaiv npog rau helicopters, tso tsheb hlau luam thiab nkoj, tiv thaiv plhaub rau radars, thiab npog npog. , Lub tsho tiv thaiv mos txwv, lub tsho tiv thaiv tiv taus, ntaub thaiv npog, thiab lwm yam. Nws muaj qhov zoo ntawm lub teeb thiab muag muag, thiab nws cov txiaj ntsig tiv thaiv mos txwv zoo dua li ntawm aramid. Nws tau dhau los ua cov khoom siv tseem ceeb nyob hauv Asmeskas kev lag luam tsho tiv thaiv mos txwv. Ib qho ntxiv, qhov cuam tshuam tshwj xeeb thauj tus nqi U/p ntawm UHMWPE cov khoom siv fiber ntau yog 10 npaug ntawm cov hlau, thiab ntau dua ob zaug ntawm iav fiber ntau thiab aramid. Kev tiv thaiv mos txwv thiab kev kub nyhiab ua los ntawm cov khoom siv ua kom muaj fiber ntau ntxiv rau txawv teb chaws tau dhau los hloov pauv rau cov kaus mom hlau thiab cov aramid-txhawb nqa cov kaus mom hlau sib xyaw.
Aerospace
Hauv kev tsim vaj tsev dav hlau, vim lub cev nyhav, lub zog siab thiab qhov cuam tshuam zoo ntawm cov khoom siv fiber ntau, nws tsim nyog rau ntau lub dav hlau wingtip cov qauv, cov qauv siv dav hlau thiab lub dav hlau. Cov fiber kuj tseem tuaj yeem siv los ua kev dhia dhia nrawm rau tsaws ntawm qhov chaw thauj mus los thiab cov hlua rau tshem tawm cov khoom hnyav ntawm lub dav hlau, hloov cov tsoos hlau hlau thiab cov hlua hluavtaws hluavtaws, thiab nws txoj kev txhim kho yog nrawm heev.
Civil
(1) Kev thov cov hlua thiab cov hlua: hlua, hlua, nkoj thiab nuv ntses ua los ntawm cov fiber no haum rau kev tsim vaj tsev thiab yog thawj zaug siv cov fiber. Nws feem ntau yog siv rau cov hlua tsis zoo, cov hlua hnyav, cov hlua khaws cia, cov hlua rub, cov hlua caij nkoj thiab cov kab nuv ntses. Cov hlua ua los ntawm cov fiber no muaj qhov tawg ntev hauv nws tus kheej qhov hnyav uas yog 8 npaug ntawm cov hlua hlau thiab 2 zaug ntawm aramid fiber. Txoj hlua yog siv rau cov hlua khi ruaj khov ntawm cov supertankers, cov chaw ua haujlwm hauv hiav txwv, lub teeb pom kev, thiab lwm yam, thiab daws cov xeb thiab xeb, xeb dej, thiab ultraviolet degradation ntawm nylon thiab polyester hlua uas tau ntsib yav dhau los siv cov hlua hlau. Lub zog ntawm cov hlua raug txo thiab tawg. , Qhov teeb meem ntawm kev hloov pauv ntau zaus.
(2) Cov khoom siv kis las kis las: lub kaus mom hlau tiv thaiv kev nyab xeeb, snowboards, cua daj cua dub nthwv dej, pas nrig nuv ntses, nuv ntses thiab caij tsheb kauj vab, cov laug cam, cov dav hlau uas hnyav tshaj plaws, thiab lwm yam tau ua rau cov khoom lag luam kis las, thiab lawv cov kev ua tau zoo dua li cov khoom siv ib txwm muaj.
(3) Siv los ua cov khoom siv tshuaj lom neeg: Cov khoom siv ua kom muaj fiber ntau tau siv hauv cov ntaub ntawv tais diav, kho mob thiab cog yas yas. Nws muaj biocompatibility zoo thiab ua haujlwm ntev, thiab muaj kev ruaj ntseg siab. Ua rau ua xua thiab tau siv hauv daim ntawv thov tshuaj. Nws kuj tseem siv hauv hnab looj tes kho mob thiab lwm yam ntsuas kev kho mob.
(4) Hauv kev lag luam, fiber ntau thiab nws cov khoom siv sib xyaw tuaj yeem siv ua lub thawv ntim siab, siv txoj siv thauj khoom, lim cov khoom, lub rooj tsav tsheb tsis zoo, thiab lwm yam; hauv kev tsim kho, nws tuaj yeem siv ua phab ntsa, faib cov qauv, thiab lwm yam. Txhim kho qhov nyuaj ntawm cov cement thiab txhim kho nws qhov cuam tshuam.
Kev siv: lub tsho tiv thaiv mos txwv thiab lub kaus mom hlau, tiv thaiv khaub ncaws hnav, nkoj, cov hlua, cov hlua kho qhov muag, cov pa taws thiab cov ntxaij lim dej, thiab lwm yam.
