Kevlar - yog dab tsi? Khoom Kevlar. manufacture Kevlar

Txhua tiam, nyob rau hauv xws li ib tug ib ntus era, lawv cov kev cai thiab tej ntsiab cai, uas yuav tsum tau rau cov kev mus ncig thiab zoo ntawm lub neej. Raws li, rau lub acceleration ntawm scientific thiab cov kev kawm nyob rau hauv tag nrho cov sectors yuav tsum nce rau hauv lub dav npaum li cas, thiab ib tug tshiab lub sij hawm dictates nws cov kev cai. Yog li ntawd yog dab tsi zoo ntawm kev zam ntawm tej yam uas yuav muaj xws li Kevlar kov tsis tau tsuas yog cov tshwj xeeb units, nrog rau cov tub rog, tab sis kuj cov txiv neej dog dig nyob rau hauv txoj kev uas hwm lawv cov kev nyab xeeb thiab kev hlub kev nplij siab.

Kevlar: yog dab tsi?

Check ntev Kevlar fibers woven rau hauv tus qauv txoj kev loj hlob nyob rau hauv lub tsheb, kev tsim kho, ua tub rog industries, displacing tsawg kawg yog cov khoom thiab cov tswv yim hlau. "Woven" threads los ntawm organic khoom tau ua indispensable tsuas vim hais tias ntawm lawv cov cim yam ntxwv. Yog li ntawd tam sim no peb xav txog nyob rau hauv kom meej lo lus nug ntawm Kevlar - dab tsi nws yog ib thiab kawm nws cov keeb kwm ntawm tshwm sim.

Luv luv txog cov kev tshwm sim

Tshiab polymer nyob rau hauv ib lub siab, yog tus "me nyuam" ntawm nws Majesty sij hawm, yug nyob rau hauv Dupont-piv, uas twb nyob rau hauv lub sij hawm uas yuav tsum tau nws credit cov invention yog ib cov khoom xws li ntaub lis loos. Ces, nyob rau hauv 1964, cov kev tshawb fawb pab pawg neeg nrhiav ib tug tov yuav ua li cas los hloov tus steel qaum nyob rau hauv lub tsheb log tsheb ntawm ib tug ho sib zog polymeric filaments, xws li polyaramid. Raws li, qhov kev ua si yog tsis yooj yim, vim hais tias koj thawj zaug yuav tsum yaj polyaramids (uas nyob rau hauv nws tus kheej tsis yog ib qho yooj yim ua hauj lwm), thiab ces kom tau ib tug array ntawm "tig" threads. Ib tug zoo tshwm sim tau tau tiav Stefani Kvolek. Nws muaj kev tswj kom tau lub fibers exceptional zog, uas tom qab xeem tsom staggering tau - tus tshiab xov muaj nyob muaj zog tshaj hlau.

Tab sis hais tias yog tsuas yog thaum pib ntawm ib tug ci ntsa iab keeb kwm ntawm cov khoom no. Kevlar ntaub nyob rau hauv kev ua lag luam nyob rau hauv 1975, thiab txij thaum ntawd los, cov tsis muaj kev thov txhob yws yws. Thiab nws tsim ib tug ntau lawm, yog li ntawd Dupont tsis nres. Lub tuam txhab muaj hnov nyiaj txiag kev nqis peev, aimed ntawm modernizing lub patented Kevlar cov ntaub ntawv thiab muab nws tuaj kawm.

raws li txoj cai niaj hnub no

Tam sim no peb tuaj mus rau peb lub sij hawm. Niaj hnub nimno Kevlar - yog dab tsi? Qhov no kuj ceeb tias teeb thiab muag muag khoom uas hluav taws tsis hlawv txawm tsis yog smolders dej txig absorbs uas integuments "ua pa", thiab yog li rau nws muaj zog tshaj steel ntawm lub sij hawm, kev tswj cov load ntawm so ntawm 2500 N . Yog, thiab cov nqaij mos ua heev yooj yim thiab yuav tsis tau ib tug nqaim seem ntawm cov khoom.

Yuav ua li cas yuav ua rau

Fiber-txoj kev polymers yog ua thaum uas tsis muaj kub los ntawm polycondensation nyob rau hauv cov tshuaj. Mus kav ntxiv reagents thiab do kwm. Los ntawm no polymer tov yog tso tawm nyob rau hauv daim ntawv ntawm cov khoom noj los yog gel. Tom ntej no, nws yog ntxuav thiab qhuav. Lub polymer twb ces yaj nyob rau hauv muaj zog acids (e.g., sulfuric acid). Los ntawm resulting tov extruded filaments thiab fibers yog tsim. Lawv ntxuav thiab qhuav.

Kevlar fiber - polymer crystallizes. Lawv cov qauv yog yus muaj los ntawm ib tug high degree ntawm rigidity. Qhov no yog vim muaj cov benzene rings. Raws li cov qauv Kevlar koom mus rau ib tug crosslinked polymer. Nws yog tsim nyob rau hauv daim ntawv ntawm cov kev yarns coj txawv fineness thiab cov qauv. Cov nab npawb ntawm cov fibers nyob rau hauv lub fibers yuav sib txawv ntawm 130 mus rau 1000 nyob rau hauv qhov siv thiab ua Kevlar ntaub thiab los ntawm 500 txhiab rau 10 nyob rau hauv lub chaw ua khoom ntawm cords thiab ropes .. Qhov no cov ntaub ntawv uas yog muaj nyob rau hauv daim ntawv ntawm cov rovings, fabrics thiab yarns. Opaque fibers, lawv txhais li cas txoj kab uas hla - 11 microns.

Liaj teb ntawm daim ntawv thov

Kevlar pom nws daim ntawv thov nyob rau hauv cov lag luam uas tseem ceeb heev coj kuj thiab thermal stability, tsis tshua muaj cov yam ntxwv nruj thiab ntau lightness thiab zoo heev zog ntawm ib tug tsawg ceeb thawj. Nws yog tsis xav tsis thoob hais tias qhov no cov ntaub ntawv uas tuaj "mus rau lub tsev hais plaub" nyob rau hauv qhov siv thiab ua ntawm koj tus kheej tiv thaiv cov khoom, xws li cov mos txwv-pov thawj vests, nyiam.

Kevlar: Tiv thaiv khaubncaws

Niaj hnub no ua txawv cov khaub ncaws Kevlar tsim tsis tsuas rau cov tub rog thiab ntau yam tshwj xeeb units, tab sis kuj rau cov neeg uas xaiv ultraaktivny txoj kev ua neej thiab vwm nyob rau tib lub mus yos hav zoov los yog airsoft. Ntawm cov hoob kawm, airsoft nowhere Kevlar armor nrog ib theem siab ntawm kev tiv thaiv thiab ntxiv armor phiaj, tab sis qhov T-shirt nrog tshwj xeeb Kevlar inserts yuav heev yam. Nyob rau hauv tas li ntawd, cov ntsiab yog ib qho yooj yim mus nkaum nyob rau hauv lub outerwear, thiab haum tsim cov qauv uas tsim.

Tej zaum cov feem ntau nrov khoom ntawm Kevlar yuav suav hais tias Armed helms, tactical hnab looj tes thiab, ntawm chav kawm, lub cev tej cuab yeej. Incidentally, los ntawm no cov ntaub so ntswg thiab tsim cov passive tiv thaiv txhais tau tias, adopting NATO.

Tiv thaiv koj ob txhais tes

Tactical hnab looj tes nrog Kevlar nyob rau hauv daim ntawv ntawm cov kev tiv thaiv inserts rau lub xib teg thiab knuckles yuav tsis tau tsuas yog tiv thaiv lub caj npab los yog puas nyob rau hauv ib tug kev sib tsoo, piv txwv li, nrog rau cov hniav ntawm tus yeeb ncuab, tab sis kuj zoo heev txhim khu tej yam, ua rau nws ib tug doog ntshav. Qhov no zoo niaj hnub sib npaug ntawm tooj dag knuckles. Muab lub dag lub zog, warmth thiab ya raws thiab kev puas tsuaj stability ntawm xws accessories nyob rau hauv xyoo tsis ntev los tsis tau tsuas yog nrov ntawm cov neeg ua hauj lwm tshwj xeeb units, tab sis kuj heev, txoj kev tua hluav taws, active lifestyles. lawv kuj nyob rau hauv kev thov los ntawm cov neeg uas muaj tsaus txoj kev ntawm nws cov haiv neeg tas ua zoo-nrhiav kev ntshai.

Thiab lub mos txwv thiab bayonet ... Tsis Kevlar nres?

Lub cev tej cuab yeej ntawm Kevlar yog suav tias yog ib qho ntawm feem txhim khu kev qha txhais tau tias ntawm ib tug neeg passive tiv thaiv. Nrog nws cov cim lightness, lub zog thiab txheeb ze durability ntawm no "ris tsho ua rog" muaj peev xwm los tiv thaiv tus neeg hnav los ntawm glancing blows txias riam phom thiab mitigate tej yam uas cov mos txwv ntaus, tiv thaiv lub nkag mus thiab kis ntawm cov khib nyiab.

Xaiv ib tug Bulletproof tsho khuam, raws li nyob rau hauv lub polymer siv, xav txog ib co ntawm cov nuances uas nws yog tej txiaj ntsim. Kevlar - yog dab tsi? Mos armor, uas yuav cawm tsis tau los ntawm ib tug tua rau ze ntau yam los yog tob tob ib tug riam los yog Awl, li ntawd, tsim qauv nrog tshwj xeeb txhav panels, tsim los ntxiv nqus ntawm tej yam.

Rau tag nrho nws cov disadvantages

Qhov tsis zoo ntawm Kevlar muaj xws li lub teeb rhiab heev - thaum ntev nyob twj ywm nyob rau hauv lub hnub txuj ci tseem ceeb cov ntaub ntawv uas pib mus ua txhaum down, txawm hais tias heev, heev maj mam. Pom kev tiv thaiv txhais tau tias los ua Inserting ntsiab nrog Kevlar threads nyob rau hauv ib tug tuab daim ntaub.

Tus nqi ntawm cov khoom uas paraamidnymi yarns yog txaus siab, thiab hais tias nws tes nrog rau lub universal "kevlarizatsii". Yuav kom equip lub pab tub rog nrog tactical khoom ua los ntawm cov khoom no yuav them taus xwb kev lag kev luam tsim lub teb chaws nqe lus.

Qhov kawg ntawm

Rau hnub tim, nyuaj heev los muab passive tiv thaiv tsis Kevlar fibers, ua los ntawm ib tug ntaub cev ris tsho ua rog thiab nyiam, nyiam tau txais kev cawmdim ntau lub neej. Yog li ntawd, creators yuav ua tau zoo siab rau. Tab sis manufacturers yuav tsum nthuav zus tau tej cov Kevlar thiab tsis tu ncua kom nws zoo yam ntxwv.
