UHMWPE fiber ntau tau dhau los ua ib qho tseem ceeb ntawm high-tech fiber ntau vim nws cov kev ua tau zoo heev, tab sis vim nws cov yam ntxwv ntawm cov qauv, nws muaj qee qhov kev ua haujlwm tsis zoo uas txwv nws cov ntawv thov ntau yam. Ntau yam kev siv lub cev thiab tshuaj xws li kev kho ntshav ntshav thiab oxidation tuaj yeem siv los hloov kho qhov chaw ntawm UHMWPE fibers, uas tuaj yeem txhim kho lawv cov khoom tsis muaj zog xws li kub tsis kam, cuam tshuam, thiab nkag mus rau qhov sib txawv. Kab lus no muab cov ncauj lus kom ntxaws txog cov kev hloov kho ntawm cov fiber ntau no thiab nws cov kev siv hauv cov hlua, cov khoom siv tiv thaiv, thiab lwm yam.
Ultra siab molecular hnyav polyethylene fiber (UHMWPE) yog ib tug high-kev ua tau zoo fiber ntau uas tau tshwm sim tom qab carbon fiber thiab aramid fiber. Nws yog tsim los ntawm ultra-siab molecular hnyav polyethylene los ntawm high-pressure khoom extrusion, plasticizing yaj spinning, nto crystal kev loj hlob, super stretching los yog hauv zos super stretching, gel spinning kub stretching thiab lwm yam txheej txheem. Nws yog cov kev ua tau zoo fiber ntau nrog lub zog siab thiab cov modulus siab, thiab tseem muaj qhov ntom ntom (ntom ntom)
Lwm cov khoom zoo xws li 0.97g/cm3, tshuaj tiv thaiv corrosion, cuam tshuam tsis kam, tsis nqus dej, thiab zoo sib xws nrog cov kab mob. Nws tau pom zoo rau daim ntawv thov kev cia siab nyob rau hauv daim teb ntawm cov ntaub ntawv tshwj xeeb thiab cov ntaub ntawv sib xyaw.
Txawm li cas los xij, vim lub fact tias UHMWPE fibers lawv tus kheej yog linear ntev chains tsim los ntawm non-polar methylene pawg, tsis muaj zog intermolecular quab yuam ntawm fiber ntau molecules; Qhov saum npoo ntawm cov fibers yog chemically inert, ua rau nws nyuaj rau tsim tshuaj bonds nrog cov resin; Smooth nto tshwm sim los ntawm high degree ntawm crystallization thiab orientation tsim los ntawm high magnification stretching nyob rau hauv ntau lawm. Kev sib xyaw ua ke ntawm tag nrho cov khoom no ua rau lub zog saum npoo ntawm cov fibers me me, ua rau nws nyuaj rau kev sib txuas lus zoo nrog cov matrix resin thaum siv los ua cov khoom siv ntxiv rau cov ntaub ntawv sib xyaw. Ntau cov kev tshawb fawb tau pom tias cov ntaub ntawv sib xyaw ua los ntawm UHMWPE fibers feem ntau puas nyob rau hauv daim ntawv ntawm interlayer puas thaum siv. Lub hauv paus ua rau ntawm qhov teeb meem no nyob rau hauv cov yam ntxwv ntawm UHMWPE fibers lawv tus kheej thiab cov yam ntxwv ntawm cov txheej txheem ntau lawm. Yog li ntawd, kev ua tau zoo ntawm kev sib txuas ntawm cov ntaub ntawv sib xyaw ua los ntawm UHMWPE fibers tau dhau los ua qhov kev txhawj xeeb tseem ceeb hauv kev npaj cov ntaub ntawv sib xyaw.
