Kevlar - chii? Material Kevlar. kugadzira Kevlar

chizvarwa ose, kugara kana kwekanguva nguva, mitemo yavo uye nenheyo, zvinodiwa kuti kufamba uye kunaka kwoupenyu. Saizvozvowo, nokuti kumhanyisa musayenzi uye michina mberi sectors zvose zvinofanira kuwedzera vakawanda zvazvingava, uye imwe nguva itsva dzokwenyu pachake mitemo yayo. Saka chii fashoni zvinhu mutsa zvinosanganisira Kevlar akabata kwete chete kushandiswa dzakabatana, kusanganisira muchiuto, asi vo munhuwo zvake mumugwagwa vanokoshesa vakachengeteka zvavo uye vanoda kunyaradzwa.

Kevlar: chii?

Kunogara refu Kevlar fibers yakarukwa kupinda nemamiriro kukura mune motokari, kuvaka, maindasitiri zvechiuto, displacing kanenge ubatanidzwewo zvikukutu uye rinoshanda simbi. "Rakarukwa" shinda kubva makemikari acho zvava kushaika nokungoti dzavo nedzimwe zvatariswa. Saka ikozvino tiri funga zvakadzama mubvunzo Kevlar - chii uye kudzidza nhoroondo yake chiitiko.

Muchidimbu pamusoro chiitiko

New polymer mupfungwa, aiva "mwana" ukuru hwake Chance, akaberekerwa Dupont Labs, izvo kare panguva iyoyo aiva wayo chikwereti nokugadzirwa iri zvinhu zvakadai zvinhu zvenaironi. Zvadaro, muna 1964, boka tsvakurudzo akatsvaka mhinduro sei kutsiva simbi tambo iri motokari matai pane yekudyidzana vakareruka polymeric filaments, akadai polyaramid. Saka, basa haana nyore, nokuti unofanira kutanga kuiparadza polyaramids (izvo pachako hakusi nyore), uye zvadaro kuti inofa "kuruka" shinda. A akanaka mugumisiro kwave kubudirira Stefani Kvolek. Iye akakwanisa kuwana fibers chaizvo simba, iyo pashure yokuedzwa akaratidza wokudzedzeresa migumisiro - neshinda itsva aoneka vakasimba kupfuura simbi.

Asi kuti kwaingova kutanga kwakajeka nhoroondo iyi zvinhu. Kevlar jira akaonekwa pamusika muna 1975, uye kubvira ipapo, kushaya kudiwa kwete kugunun'una. Uye anosika firimu, saka kuti Dupont haagumiri ipapo. The kambani anopa kuoneka Investments zvemari, zvainanga modernizing ari patented Kevlar zvinhu uye kuzvipa nani unongotaura.

Status nhasi

Zvino tinosvika pachedu nguva yedu. Modern Kevlar - chii? Izvi zvinoshamisa chiedza uye akapfava zvinhu kuti moto haachemeri kunyange asiri smolders mwando zvakakwana absorbs kubvumira integuments "fema", uye saizvozvo simba raro pane simbi dzimwe nguva, tiine mutoro pana kwemasikati pakati 2500 N . Hongu, uye zvinyama processing zvikuru nyore uye haatarisiri chikamu nhete zvishandiswa.

How kuti

Fiber-nokuumba Polymers anobudiswa panguva yakaderera tembiricha kubudikidza polycondensation mune mhinduro. Enda yakareba akawedzera reagents uye akamutsa zvakasimba. Kubva ichi polymer inotoda kusunungurwa muchimiro mafufu kana gel. Next zvinonzi kushambidzwa uye waoma. The polymer akabva zvazvichanyungudutswa simba acids (semuenzaniso, sulfuric acid). Kubva zvichiguma mhinduro extruded filaments uye fibers vari aumba. Vashamba nokuoma.

Kevlar faibha - polymer crystallizes. mamiriro avo kunoratidzwa refu mwero Rigidity. Izvi imhaka pamberi benzene zvindori. Maererano mamiriro Kevlar anorondedzera kuti crosslinked polymer. Wakaitwa muchimiro michina pemavara vane yakasiyana fineness nechivako. Kuwanda fibers ari fibers vanogona dzinosiyana 130 kusvika 1000 muna zvaAtemisi Kevlar jira uye kubvira 500 zviuru 10 ari kugadzirwa yerwonzi namakavi .. Izvi zvinhu inowanika muchimiro rovings, machira uye nezvitsvuku. Opaque fibers, avo kunoreva dhayamita - 11 microns.

Minda chikumbiro

Kevlar anowana kushandisirwa mumaindasitiri iwayo apo zvikuru kusakara nemishonga uye chafariz pakusimba, pasi STRUCTURAL kuomarara uye kunonyanyisa nenyama uye simba kwazvo yakaderera uremu. Hazvishamisi kuti izvi zvinhu akauya "dare" iri zvaAtemisi pachake unodzivirira zvokushandisa, zvakadai bara-chiratidzo vanamajasi, nengowani.

Kevlar: Dzivirirai zvakanaka

Today akaita zvakasiyana mbatya Kevlar akagadzirirwa kwete chete nokuti uto uye siyana anokosha zviyero, asiwo vaya vanosarudza ultraaktivny mararamiro uye anopenga panguva imwe kunovhima kana Airsoft. Chokwadi, Cuba hapana Kevlar dzokurwa rurefu azvipire kudzivirirwa uye yokuwedzera dzokurwa ndiro, asi T-shirt anokosha Kevlar inoisa achava akakodzera chaizvo. Uyezve, zvinhu izvi zviri nyore kuvanda pasi outerwear, uye zvakakodzera magadzirirwo yokutevedzera dzinokudziridzwa.

Zvichida nevanhu zvibereko Kevlar anogona kunzi Armed Helms, tactical magiravhusi uye, chokwadi, muviri dzokurwa. Sezvineiwo, kubva zvinyama ichi uye kubudisa pusa kudzivirira nzira, vachigamuchira NATO.

Dzivirira maoko ako

Tactical magiravhusi pamwe Kevlar muchimiro anodzivirira inoisa pamusoro emichindwe uye zvipfundo zvomunwe haagoni kudzivirira chete ruoko rurege wakaremara vari kudhumhana Somuenzaniso, pamwe meno muvengi, asi kuwedzera matambudziko kwazvo, zvichiita kuti mbundishire. mhando iyi ano zvakafanana zvipfundo zvomunwe zvendarira. Akapiwa simba, ushamwari uye unyoro uye kukuvara kugadzikana nenhumbi dzakadaro mumakore achangopfuura rakakurumbira kwete chete pakati mudonzvo unyanzvi dzakabatana, asi akanyanyisa, vanodzima mumugwagwa, vanoshingaira mararamiro. vari muna charehwa nevaya vane migwagwa rima yake yaakaberekerwa munharaunda chikonzero yokutya.

Zvino bara uye bhayoneti ... Ko Kevlar kurega?

Muviri zvombo Kevlar anonzi mumwe akavimbika kupfuura nzira munhu pusa kudzivirirwa. With kwayo yakasiyana nenyama, simba uye hama mukurumari izvi "zvombo" anokwanisa kudzivirira akaripfeka kubva Anodongorera zvibhakera zvombo inotonhora uye kuderedza matambudziko ari mabara vouta kutadzisa kupinda uye kupararira marara.

Kusarudza bara repfuti, inobva polymer kushandiswa, funga zvimwe nuances zvaakanga hwakapiwa. Kevlar - chii? Soft dzokurwa, chisingafaniri kuponesa kubva pena zvemandorokwati kana rakapinza banga kana mutsunda, saka dzakabudirira yokutevedzera uchinyanya vanachandagwinyira ukomba, yakagadzirirwa zvakare kupinza matambudziko.

For zvazvakanakira zvose

Zvazvakashatira kevlar zvinosanganisira chiedza utetsa - panguva refu kugara kwezuva chishamiso zvinhu rinotanga kuputsa, kunyange kwazvo, zvishoma nezvishoma chaizvo. Zvakanyanya Kunaka Panguva Yepamuviri kudzivirirwa pachishandiswa zvakavharwa kuisa zvinhu pamwe Kevlar shinda mune jira.

Mutengo chigadzirwa pamwe paraamidnymi pemavara iri zvakakwana yakakwirira, uye kuti kuzvirega zvichikanganisa waifarirwa "kevlarizatsii". Kushongedzera hondo pamwe tactical zvigadzirwa kubva ichi zvinhu mari chete zvemari dzakabudirira nyika mazwi.

Pamugumo

To musi, zvakaoma chaizvo kudzivirira pusa pasina Kevlar fibers, wakaitwa Mucheka muviri zvombo uye nenguwani, ngowani ndakaponesa upenyu zhinji. Saka creators kudada. Asi vagadziri vanofanira kuwedzera kugadzirwa Kevlar uye kuramba kuvandudza ayo unhu unhu.
