UHMWPE UD khoom

Polymer tom qab ntawv

Nws ua rau kev nkag siab zoo rau cov engineers pib lawv qhov kev ntsuam xyuas ntawm UHMWPE UD cov ntaub ntawv nrog cov fibers. Cov khoom no yog tsim los ntawm ultrahigh molecular hnyav polyethylene, uas muaj ntev, zoo heev orientated polymer chains raws filament axis. Lub zog tensile siab, siab modulus, thiab qhov ceev ntawm tsawg tshaj li ib gram ib cubic centimeter - uas ua rau nws sib zog tshaj dej -tag nrho cov qia los ntawm qhov kev taw qhia no. Qhov kev sib xyaw ua ke no tsis tshua muaj rau siab - lub zog steel tuav. Vim li no, cov khoom siv tib yam tuaj yeem pom nyob rau hauv radomes, airborne tanks, xov hlau, nuv ntses nets, thiab bowstrings -tag nrho cov uas yuav tsum tau muaj tsawg kawg nkaus qhov hnyav rau kev siv hnyav.

Ntau tshaj Fiber Ntau

Cov polymer yog lub hauv paus ntawm cov yam ntxwv no. Dimensional stability yog guaranteed los ntawm kev nqus dej tsawg. Nws yog ib qho zoo tshaj plaws hluav taws xob insulator uas yog impervious rau UV teeb, hnyav, thiab corrosion. Nws ua rau pom kev nyuaj thiab rip tsis kam ntawm qhov kub thiab txias, uas yog qhov tseem ceeb rau cov panels siv nyob rau hauv lub polar thiab marine cheeb tsam los yog nyob rau hauv lub tub yees. Cov khoom siv UD no tsim nyog rau cov khoom hnav hauv cov tshuab nrog rau cov khoom siv ballistic vim nws tsis tshua muaj coefficient ntawm kev sib txhuam thiab siab puas.

Txawm li cas los xij, thaum cov neeg siv khoom ntsuas cov khoom tsuas yog raws li nws cov fibers, lawv ua yuam kev. UD cov nplooj ntawv yog ua los ntawm unidirectionally txheej fibers uas yog laminated rau hauv 0℃/ 90℃orthogonal txheej tom qab muab txuas rau ib tug thermoplastic resin. Zoo ib yam li cov fibers, cov khoom siv tus cwj pwm nyob rau hauv kev cuam tshuam yog txiav txim los ntawm cov resin pick-up, alignment angles, thiab txheej txheej. Ob lub yob nrog tib qib nominal yuav ua txawv yog tias lawv tsis raug impregnated.

Tsim nyog tus lej uas tseem ceeb

Yog li ntawd, thaum muab ntawv pov thawj UHMWPE UD cov ntaub ntawv, nug txog cov lej uas tswj kev siv tiag tiag, xws li batch traceability, nplaum cov ntsiab lus, fiber ntau alignment angles, thickness uniformity, thiab cheeb tsam qhov hnyav thiab kam rau ua. Tsuas yog tom qab kev kho siv cov ntaub ntawv tuaj yeem muab piv rau aramid. Thaum nws los txog rau qhov hnyav thiab cuam tshuam kev ua haujlwm, UHMWPE prevails; Nyob rau hauv cov xwm txheej uas kub raug predominates, aramid prevails. Cov neeg siv khoom yeej ib txwm qhia kom qhia meej daim ntawv thov ua ntej cov khoom hauv peb lub khw.
