Kevlar - ntoni na? Kevlar eziphathekayo. Kevlar

Zonke sizukulwana, ehlala mhlawumbi kwixesha yethutyana, imithetho kunye nemigaqo yawo, iimfuno intshukumo kunye nomgangatho wobomi. Ngako oko, ngenxa yokunyusa inkqubela yenzululwazi kunye nobugcisa kuwo onke amacandelo kufuneka ukwandisa izinga jikelele, kunye nexesha omtsha sithi makubekho imithetho yayo. Ngoko ke yintoni uhlobo ukumila zinto ziquka le Kevlar ingafiki nje iiyunithi ezizodwa, kubandakanywa emkhosini, kodwa umntu eziqhelekileyo esitratweni abaxabise ukhuseleko lwabo nothando intuthuzelo.

Kevlar, yintoni na?

imicu Ehlala Kevlar elide zayinxalenye kuphuhliso isakhiwo, ulwakhiwo, amashishini zomkhosi izithuthi, kancinane intsimbi ubuncinane ngokungaphelelanga okuqinileyo and practical. "Olukiweyo" imisonto ukusuka izinto eziphilayo iye ebalulekileyo ngenxa nje yokuba iimpawu zabo ezizodwa. Ngoko ke ngoku esiza kuxubusha ngayo ngokweenkcukacha umbuzo Kevlar - luyintoni kwaye bafunde imbali yakhe ingenzeka.

Ngokufutshane mayelana umcimbi

Polymer entsha ngengqiqo, waba "sana" bobungangamsha bakhe Chance, owazalelwa Dupont labs, nto leyo esele ngelo xesha kwafuneka ngetyala kwayo wayila kukho izinto ezifana nenayiloni. Emva koko, ngo-1964, iqela lophando wafuna isicombululo indlela ukubuyisela intambo ophuma amavili zemoto kwindawo zixhobo kakhulu lula polymeric, ezifana polyaramid. Ngako oko, umsebenzi wayengekho elula, ngenxa yokuba kufuneka kuqala ukunyibilikisa polyaramids (nto leyo asinto umsebenzi olula), yaye emva koko ukuze ufumane uluhlu lwe "ejikelezayo" imisonto. Isiphumo positive kuye kwafezwa stefani Kvolek. Wakwazi ukufumana imicu amandla ezizodwa, apho emva kokuba uvavanyo wabonisa iziphumo ukugxadazela - ubonakele umsonto entsha yomelele kunentsimbi.

Kodwa yaba sisiqalo yimbali okhanyayo kulo mbandela. Kevlar Ilaphu gqi kwimarike ngo-1975, yaye ukususela ngoko, ukunqongophala kwemfuno hayi ukukhalaza. Oko, yaye kunika imveliso, ukuze Dupont akayeki apho. Le nkampani ibonelela utyalo-mali buqapheleke, ezijolise ukuphucula izinto Kevlar eqinisekisiwe kwaye uyinike nokuphuculwa komsebenzi.

isimo namhlanje

Ngoku siza kwixesha lethu. Kevlar Modern - ntoni na? Kwaye okumangalisayo ukukhanya eziphathekayo athambileyo umlilo akabi, yaye kunzima engamabhodlo, ukufuma ngokubamba ngokugqibeleleyo, ovumela integuments "uphefumla", yaye ngaloo ndlela emandleni ako kunentsimbi maxa wambi, ukugcina umthwalo kwi umda phakathi 2500 N . Ewe, kwaye izicwili ukuzilungisa kakhulu lula kwaye ayifuni icandelo elimxinwa izixhobo.

Indlela yokwenza

Iipholima Umthambo-yakheka ziveliswa kwiqondo lobushushu esezantsi polycondensation in isisombululo. Hamba uye uhlale wezenzi yongezwe siwagxobhagxobhe ngamandla. Ukususela kule sisombululo Polymer ngesi ngohlobo kwiimvuthuluka okanye gel. Okulandelayo, kokuhlanjwa kwaye womile. Le Polymer koko iqhawulwa asidi eyomeleleyo (umz, sulphuric acid). Ukususela isisombululo ngenxa kwayo extruded neerhali kwakheka. Ziye ke ndahlamba yaye yomile.

Kevlar fiber - Polymer crystallizes. ahlelwe iphawulwa iqondo eliphezulu ngqongqo. Oku kungenxa ubukho amakhonkco benzene. Ngokutsho isakhiwo Kevlar inxulumene Polymer crosslinked. Yenziwe ngokohlobo ngemisonto yobugcisa yokuba fineness ezahlukeneyo kunye nesakhiwo. Inani imicu imicu ziyahluka ukusuka 130 ukuya ku-1000 xa kusenziwa le Kevlar ilaphu yaye ukususela 500 lamawaka 10 ekwenziweni ezintambo neentambo .. Le nkcazelo ifumaneka ngohlobo rovings, amalaphu aqhelekileyo kunye nebomvu. okuzenzela ngaphaya kwawo, ubukhulu wabo athetha - 11 microns.

Fields of application

Kevlar ifumana isicelo yayo kuloo mveliso apho kubaluleke kakhulu ukumelana kukuwohloka nozinzo thermal, ukuqina noshowo eliphantsi ndandifeketha na ubukhulu kunye namandla etshatsheleyo ubunzima elisezantsi. Ayimangalisi into yokuba le nto wafika "enkundleni" ekwenziweni izixhobo zakho, ezifana bullet-proof vests, iminqwazi.

Kevlar: Khusela kakuhle

Namhlanje wenza iimpahla ezahlukileyo Kevlar ezingenzelwanga kuphela kwiiyunithi zemfundo eneemfuno ezizodwa zomkhosi ezahlukeneyo, kodwa abo bakhetha ultraaktivny yokuphila kunye crazy kwi ukuzingelwa enye okanye airsoft. Kakade ke, airsoft isikrweqe ndawo Kevlar kunye inqanaba eliphezulu lokukhuselwa neepleyiti isikrweqe ezongezelelweyo, kodwa T-shirt kunye ezifakelwa Kevlar awodwa aya kuba ezifanelekileyo kakhulu. Ukongeza, ezi zinto kulula ukuzimela phantsi outerwear, kwaye izikhokelo design efanelekileyo.

Mhlawumbi iimveliso uthandwayo Kevlar unako kuqwalaselwa helms ngemipu, iiglavu ezithile kunye, Kakade, esi zokuzikhusela. Phela, kule izicwili kunye nokuvelisa iindlela zokukhusela zezenzi, bethatha NATO.

Nikhusele izandla zenu

iiglavu yamacebo okulwa ne Kevlar ngokohlobo ifaka zokuzikhusela ezintendeni kunye knuckles ayikwazi kuphela ukukhusela ingalo ekubeni eyonakalisiweyo kungquzulwano, umzekelo, kunye amazinyo lutshaba, kodwa ukwandisa kakhulu impembelelo, iyenza ukutyumka. Olu hlobo elingana namhlanje knuckles zezobhedu. Ngenxa amandla, ubushushu kunye ukufuma kunye nozinzo umonakalo lwezincedisi ezinjalo kwiminyaka yakutshanje uthandwa kungekuphela phakathi kwabasebenzi kweeyunithi ezizodwa, kodwa kakhulu, izilwi, zokuphila esebenzayo. ukuba nabo zifunwa ngabo ezitalatweni ezimnyama zomthonyama endaweni yoko uloyiko lwakhe kakuhle liqinisekile.

Kwaye ke imbumbulu yaye onencula ... Ngaba Kevlar ukuyeka?

Body isikrweqe Kevlar igqalwa enye indlela linokuthenjwa yokuzikhusela ngamnye kwisixando sokwenziwa. Ngenxa yesandi ihluke, amandla ixesha elide kangakanani le "sikrweqe" uyakwazi ukukhusela uyinxibileyo ukuba zasikrwaqula izithonga izixhobo ebandayo kunye nokudambisa iimpembelelo iimbumbulu hit, ekuthinteleni umthondo kunye nokwanda nobutyobo.

Ukukhetha yangaphantsi elukwe yebullet, esekelwe Polymer esetyenzisiweyo, cinga ezinye bokuqonda kunye ngawo sinikezwe. Kevlar - ntoni na? isikrweqe Soft, singayi ukugcina edubuleyo ezikufutshane okanye luchukumisa imela okanye ke inyatyhowa, ngoko imifuziselo ngophuhliso ngemivalo ezikhethekileyo engqongqo, yenzelwe ukuba ufunxe impembelelo.

Ngokuba zonke nobubi bayo

Bobubi Kevlar ziquka uvakalelo light - ngexesha elide ahlale ummangaliso ilanga eziphathekayo liqala ukuba ndiludilize, nangona kakhulu, kancinci kakhulu. iindlela zokukhusela Optimal zaba Ifaka izakhi Kevlar imisonto elaphini zamafu.

Ixabiso le mveliso kunye ngemisonto paraamidnymi liphezulu ngokwaneleyo, nokuba kuphazamisa "kevlarizatsii" jikelele. Ukuxhobisa umkhosi kunye iimveliso ezithile ezenziwe kule eziphathekayo ukufikelela imigaqo lizwe kuphela kuphuhliswa ngokwezoqoqosho.

Ekupheleni

Ukuza kuthi ga ngoku, kunzima kakhulu ukuba ukunika ukhuselo kwizifo ngaphandle kwimicu Kevlar, ezenziwe lilaphu umzimba isikrweqe kunye nezigcina, nezigcina-ntloko ziye zasindisa ubomi obuninzi. Ngoko ke abasunguli sibe nebhongo kakhulu. Kodwa abavelisi kufuneka ukwandisa imveliso Kevlar kunye ngokuqhubekayo ngcono iimpawu zayo umgangatho.
