Ballistic Qib UHMWPE Xov Paj

UHMWPE Xov Paj rau Ballistic Material Production

Ultrahigh molecular hnyav polyethylene yarns ntawm qib ballistic yog siv los ua cov ntaub ntawv raw rau siab -kev tiv thaiv kev ua haujlwm, qhov uas tsis muaj qhov hnyav thiab lub zog tshwj xeeb yog qhov tseem ceeb. Ultrahigh molecular hnyav polyethylene yog ib qho ntawm cov fibers muaj zog tshaj plaws thiab lub teeb tshaj plaws, raws li cov ntaub ntawv nthuav tawm. Nws yog siv rau hauv cov phom tsis muaj phom, kaus mom hlau, tsho, txiav- cov khoom tiv thaiv, thiab cov ntaub ntawv mos mos. Tsis tas li ntawd, UHMWPE unidirectional cov ntaub ntawv rau tawv thiab mos armor yog tsim los siv nws.

Vim li cas UHMWPE rau Ballistic Structures

Nyob rau hauv high load strain tus nqi, nws muaj viscoelasticity zoo kawg li. Raws li lub vev xaib, UHMWPE muaj 40% siab dua qhov tshwj xeeb tshaj li aramid fibers thiab yog 15 npaug zog dua hlau ntawm qhov hnyav. Tsis tas li ntawd, nws muaj peev xwm tiv taus cov tshuaj, dej, thiab UV hluav taws xob. Nws kuj muaj peev xwm txo tau kev co thiab khoov qaug zog.

Los ntawm Yarn rau UD Khoom

UHMWPE fibers nyob rau hauv ib tug thermoplastic matrix yog siv nyob rau hauv cov ntaub ntawv lub mos txwv system. Fiber strips teeb tsa hauv 0℃/ 90℃/ 0℃/ 90℃cross qauv ua txhua txheej ntawm UD ntaub. Cov khoom tsim tau yog siv rau ob qho tib si tawv armour, xws li cov tsheb armored, tawv daim hlau, thiab cov mos txwv kaus mom hlau, thiab cov mos mos armour, xws li foob pob foob pob, mos txwv, thiab tsho khuam. Raws li qhov tshwm sim, cov xov paj tsis yog tsuas yog cov ntaub tiv thaiv tiav lawm xwb tab sis yog cov khoom siv sab saud rau kev tsim cov qauv mos txwv.

Kev xaiv cov khoom tseem tseem ceeb

Txoj kev tsim kho thiab kev ua haujlwm tsim nyog yuav tsum raug coj mus rau hauv kev txiav txim siab thaum xaiv cov ballistic - qib UHMWPE yarns. Raws li lub hauv paus, lub ultrahigh molecular hnyav polyethylene muaj ib tug hardness ntawm 20-45cN / d thiab ib tug fineness ntawm 20D mus rau 9600D. Cov ntsiab lus ntxiv tau nthuav tawm raws li 32-40g / d. Sib piv cov yam ntxwv fiber ntau nrog UD lossis cov qauv weave yog qhov tseem ceeb rau cov neeg tsim khoom ntawm cov khoom siv ballistic. Thaum khaws cov dej noo, tiv thaiv UV, thiab hnav tsis kam, UHMWPE tuaj yeem muab qhov qis- ntom ntom, siab{12}} lub hauv paus muaj zog uas xav tau rau lub teeb yuag tiv thaiv. Daim ntawv tseem sau tseg tias ultrahigh molecular hnyav polyethylene yog ze li ntawm radar{14}}pob tshab thiab muaj cov dielectric tsis tu ncua, uas tsim ib qho chaw tshiab zoo nkauj rau kev tiv thaiv ballistic.
