Ultra siab molecular hnyav polyethylene fiber ntau UHMWPE

Ultra siab molecular hnyav polyethylene fiber ntau UHMWPE

Ultra-siab molecular hnyav polyethylene fiber (UHMWPE) yog fiber ntau spun los ntawm polyethylene nrog ib tug txheeb ze molecular loj ntawm 1 lab mus rau 5 lab. Nws yog tam sim no lub zog thiab lightest fiber ntau nyob rau hauv lub ntiaj teb no. Nws yog 15 npaug zog dua steel hlau. Lub teeb heev, 40 feem pua ​​sib dua li cov ntaub ntawv zoo li aramid.

Hais txog cov khoom siv tiv thaiv hauv tebchaws, vim tias fiber ntau muaj kev cuam tshuam zoo thiab kev nqus lub zog ntau dua, nws tuaj yeem ua rau cov tub rog tiv thaiv khaub ncaws, kaus mom hlau, cov ntaub ntawv tsis muaj phom, xws li armored tiv thaiv panels rau nyoob hoom qav taub, tso tsheb hlau luam thiab nkoj, radar, thiab lwm yam. shells, missile npog, mos txwv vests, stab-proof vests, shields, parachutes, thiab lwm yam. Ntawm lawv, daim ntawv thov ntawm mos mos vests yog qhov muag pom tshaj plaws.

Nws muaj qhov zoo ntawm kev ua lub teeb thiab muag muag, thiab tam sim no tau dhau los ua lub ntsiab fiber ntau nyob hauv Asmeskas kev lag luam bulletproof vest. Tsis tas li ntawd, qhov tshwj xeeb cuam tshuam tus nqi U / p ntawm ultra-high molecular hnyav polyethylene fiber ntau cov khoom siv yog 10 npaug ntawm cov hlau, thiab ntau dua 2 npaug ntawm cov iav fiber ntau thiab aramid. Bulletproof thiab anti-riot kaus mom hlau ua los ntawm fiber ntau reinforced resin composites txawv teb chaws tau los hloov cov kaus mom hlau steel thiab aramid reinforced composite kaus mom hlau.

Txheej txheem cej luam ntawm UHMWPE fiber ntau hauv Suav teb: Tuam Tshoj yog lub teb chaws loj hauv tshuaj fiber ntau. Xyoo 2007, cov khoom siv tshuaj fiber ntau suav nrog 54 feem pua ​​​​ntawm lub ntiaj teb. Nws lub hauv paus kev lag luam yog qhov ruaj khov, tab sis txoj kev loj hlob ntawm cov khoom siv fiber ntau yog qhov qis dua. Txij li thaum kuv lub teb chaws pib kawm UHMWPE fibers nyob rau hauv 1985, Donghua University (yav tas los Tuam Tshoj Textile University) thiab Yancheng lub koom haum ntawm Polymer Materials Engineering thiab Technology tau koom nrog cov kev tshawb fawb thiab kev loj hlob qib ib tom qab, thiab tau ua ib tug series ntawm loj theoretical breakthroughs. Nyob rau hauv 1999, nws tsoo los ntawm cov khoom siv tseem ceeb. Nws tau dhau los ua lub tebchaws thib plaub los ua tus tswv ntawm kev tsim khoom thiab kev siv tshuab ntawm cov fiber ntau no tom qab Netherlands, Nyiv thiab Tebchaws Meskas.

Kev Nyuaj Siab: Los ntawm cov hlua, cov kab mooring thiab hlua nets, mus rau daim ntawv thov kev tiv thaiv lub neej, kev ua haujlwm siab textiles, composites thiab laminates, ntau yam kev siv yog dav heev. Hauv 5 xyoo thiab 10 xyoo tom ntej, qhov kev thov txhua xyoo rau UHMWPE hauv ntiaj teb yuav yog 60,000 tons thiab 100,{6}} tons raws li.
