Izinto Ezi-5 Okufanele Uzicabange Ngaphambi Kokwazi Ngezikhali Zomzimba (i-bulletproof Vest)
Izinto ezi-5 okufanele uzicabangele ngaphambi kokwazi ngezivikelo zomzimba(i-bulletproof vest)
1. Liyini i-bulletproof vest
Amavesti angangenwa yinhlamvu (Bulletproof Vest), abuye aziwe ngokuthi ama-bulletproof vests, ama-bulletproof vests, ama-bulletproof vests, ama-bulletproof vests, izinto zokuzivikela, njll., asetshenziselwa ukuvikela umzimba womuntu ezinhlamvu noma izimbotshana.I-bulletproof vest yakhiwe ikakhulukazi izingxenye ezimbili: ibhantshi kanye nongqimba olungangenwa izinhlamvu.Izembozo zokugqoka ngokuvamile zenziwe ngezindwangu ze-fiber zamakhemikhali.Ungqimba olungenanhlamvu lwenziwe ngensimbi (insimbi ekhethekile, ingxubevange ye-aluminium, ingxubevange ye-titanium), ishidi le-ceramic (i-corundum, i-boron carbide, i-silicon carbide, i-alumina), ipulasitiki yengilazi eqinisiwe, inayiloni (PA), i-Kevlar (KEVLAR), i-ultra-high. I-molecular weight polyethylene Fiber (DOYENTRONTEX Fiber), izinto zokuzivikela eziwuketshezi nezinye izinto zakha isakhiwo sokuzivikela esisodwa noma esiyinhlanganisela.Ungqimba olungangenwa izinhlamvu lungamunca amandla e-kinetic wenhlamvu noma i-shrapnel, futhi lunomphumela osobala wokuvikela kunhlamvu yejubane eliphansi noma i-shrapnel, futhi lunganciphisa umonakalo esifubeni somuntu kanye nesisu ngaphansi kokulawulwa kokucindezeleka okuthile.Amavesti angangenwa izinhlamvu ahlanganisa izikhali zomzimba zezingane, izikhali zomzimba womshayeli wendiza kanye nezikhali zomzimba.Ngokubukeka kwayo, ingahlukaniswa ngamavesti angangenwa izinhlamvu, amavesti avikela inhlamvu egcwele, amavesti avikela inhlamvu abesifazane nezinye izinhlobo.
2. Ukwakheka kwevesti elingangenwa izinhlamvu
I-bulletproof vest yakhiwe ikakhulukazi isembozo sezingubo, isendlalelo esingangenwa izinhlamvu, isendlalelo sebhafa, kanye nebhodi elingangenwa izinhlamvu.
Isembozo sezingubo ngokuvamile senziwe ngendwangu ye-fiber yamakhemikhali noma indwangu kakotini yoboya ukuze kuvikelwe ungqimba olungangenwa izinhlamvu futhi kwenze ukubukeka kube kuhle.Ezinye izembozo zokugqoka zinamaphakethe amaningana okuphatha izinhlamvu nezinye izinto.Isendlalelo esingangenwa izinhlamvu ngokuvamile senziwe ngensimbi, i-aramid fiber (i-Kevlar fiber), i-polyethylene enamandla aphezulu we-modulus nezinye izinto ezizodwa noma eziyinhlanganisela, ezisetshenziselwa ukubhampa noma ukushumeka izinhlamvu ezitshuzayo noma izingcezu eziqhumayo.
Isendlalelo sebhafa sisetshenziselwa ukuhlakaza amandla e-kinetic womthelela nokunciphisa umonakalo ongangeni.Ngokuvamile kwenziwa ngendwangu ehlanganisiwe ehlanganisiwe yamaseli avaliwe, i-polyurethane foam eguquguqukayo nezinye izinto.
Ukufakwa okungenanhlamvu kuwuhlobo lokufakwayo oluthuthukisa ikhono lokuvikela lesendlalelo sokuvikela inhlamvu, futhi kusetshenziswa kakhulu ukuvikela ekungeneni kwezinhlamvu zezibhamu eziqondile nezingcezu ezincane ezinesivinini esikhulu.
3.Impahla ye-bulletproof vest
Sonke siyazi ukuthi sidinga ukusebenzisa izinto zobuso noma zefayibha ukwenza izingubo, sisebenzise amaseyili ukwenzaizikhwama ze-canvas tote,kanye nesikhumba sokwenza izingubo zesikhumba njll. Yebo, kukhona okukhethekile okungangenwa izinhlamvu nezindwangu zezivikelo zomzimba.
Okokuqala nje, sethula ukuthi yiziphi izindwangu eziyinhloko ezingangenwa izinhlamvu nezinto ezivikela izinhlamvu
I-bulletproof vest yakhiwe ikakhulukazi izingxenye ezimbili: ibhantshi kanye nongqimba olungangenwa izinhlamvu.Izembozo zokugqoka ngokuvamile zenziwe ngezindwangu ze-fiber zamakhemikhali.
Ungqimba olungenanhlamvu lwenziwe ngensimbi (insimbi ekhethekile, ingxubevange ye-aluminium, ingxubevange ye-titanium), ishidi le-ceramic (i-corundum, i-boron carbide, i-silicon carbide, i-alumina), ipulasitiki yengilazi eqinisiwe, inayiloni (PA), i-Kevlar (KEVLAR), i-ultra-high. I-molecular weight polyethylene Fiber (DOYENTRONTEX Fiber), izinto zokuzivikela eziwuketshezi nezinye izinto zakha isakhiwo sokuzivikela esisodwa noma esiyinhlanganisela.
Ungqimba olungangenwa izinhlamvu lungamunca amandla e-kinetic wenhlamvu noma i-shrapnel, futhi lunomphumela osobala wokuvikela kunhlamvu yejubane eliphansi noma i-shrapnel, futhi lunganciphisa umonakalo esifubeni somuntu kanye nesisu ngaphansi kokulawulwa kokucindezeleka okuthile.

4. Izinhlobo zamavesti angangenwa izinhlamvu
Izikhali zomzimba zihlukaniswa zibe:
① Izivikelo zomzimba zezingane.Ifakwe amasosha ahamba ngezinyawo, osolwandle, njll., esetshenziselwa ukuvikela abasebenzi emonakalweni odalwa yizicucu ezihlukahlukene.
(Izikhali zomzimba zabantwana)
② Amavesti angangenwa izinhlamvu zezisebenzi ezikhethekile.Isetshenziswa kakhulu lapho kwenziwa imisebenzi ekhethekile.Ngesisekelo sezivikelo zomzimba wezingane, imisebenzi yokuvikela intamo, ukuvikelwa kwehlombe kanye nokuvikelwa kwesisu kunezelwa ukwandisa indawo yokuvikela;ngaphambili nangemuva kufakwe amaphakethe okufaka okufaka okuvikela inhlamvu ukuze kuthuthukiswe ukusebenza kwe-anti-ballistic.
(Amavesti angenanhlamvu kubasebenzi abakhethekile)
③Izikhali zomzimba zezikhali.Isetshenziswa kakhulu izikhali ekulweni, ingavikela ekuhlukaneni nokulimala kwegagasi lokushaqeka.
(Izikhali zempi)
Ngokwezinto zokwakha, izikhali zomzimba zihlukaniswe zibe:
① Izivikelo zomzimba ezithambile.Isendlalelo esingangenwa izinhlamvu ngokuvamile senziwe ngezendlalelo eziningi zamandla aphezulu kanye nezindwangu ze-high-modulus fiber ezifakwe umpheme noma ezenziwe nge-laminated ngqo.Lapho izinhlamvu nezingcezu kungena ungqimba olungangenwa izinhlamvu, zizokhiqiza ukugunda okuqondile, ukwehluleka ukuqina kanye nokwehluleka kwe-delamination, ngaleyo ndlela kudle amandla azo.
(Isivikelo somzimba esithambile)
②Isivikelo somzimba esiqinile.Isendlalelo se-bullet-proof ngokuvamile senziwe ngezinto zensimbi, i-high-power and high-modulus fiber laminates eyenziwe ngezinto ezihlanganisiwe ezisekelwe ku-resin ezishisayo futhi ezicindezelweyo, i-ceramics-proof proof, kanye namabhodi ahlanganiswe ne-high-modulus fiber composite.Ungqimba olungangenwa izinhlamvu zensimbi lusetshenziswa ukusebenzisa amandla eprojectile ikakhulukazi ngokuguqulwa nokuhlukaniswa kwensimbi.Ungqimba olungangenwa izinhlamvu ze-high-high-high-modulus fiber bulletproof laminate zisebenzisa amandla e-projectile ngokusebenzisa i-delamination, i-punch, ukuphuka kwe-resin matrix, i-fiber extraction kanye nokuphuka.Kusetshenziswa ungqimba olungangenwa izinhlamvu zamaceramics angangenwa izinhlamvu namandla aphezulu kanye nebhodi eliyinhlanganisela yefiber ephezulu yemodulus.Uma i-projectile enesivinini esiphezulu ishayisana nongqimba lwe-ceramic, isendlalelo se-ceramic siyaphuka noma siqhekeke futhi sisakazeke endaweni yomthelela ukuze kudle amandla amaningi e-projectile.Ibhodi eliyinhlanganisela ye-modulus fiber liphinde lisebenzise amandla asele e-projectile.
③Izivikelo zomzimba ezithambile neziqinile.Ungqimba olungaphezulu lwenziwe ngezinto eziqinile ze-ballistic, futhi ulwelwesi lwangaphakathi lwenziwe ngezinto ezithambile ze-ballistic.Lapho izinhlamvu nezingcezu zishaya ebusweni bezikhali zomzimba, izinhlamvu, izingcezu nezinto eziqinile ezingaphezulu ziyakhubazeka noma ziphukile, kudla amandla amaningi ezinhlamvu nezicucu.Izinto ezithambile zolwelwesi zimunca futhi zisabalalise amandla ezingxenye ezisele zezinhlamvu nezingcezu, futhi zidlala indima ekubhafani nasekwehliseni umonakalo ongangeni.
5. Ukwakhiwa kwamavesti angangenwa izinhlamvu
Izivikelo zomzimba zavela kuzikhali zasendulo.EMpini Yezwe Yokuqala, amabutho akhethekile ase-United States, eJalimane, e-Italy kanye namasosha ambalwa amasosha asebenzisa izivikelo zesifuba zensimbi.Ngawo-1920, i-United States yakha ivesti elingangenwa izinhlamvu elakhiwe ngamashidi ensimbi agqitshiwe.Ekuqaleni kwawo-1940, i-United States namanye amazwe aseNtshonalanga Yurophu aqala ukuthuthukisa izikhali zomzimba ezenziwe ngensimbi ye-alloy, i-aluminium alloy, i-titanium alloy, ingilazi yensimbi, izitsha zobumba, inayiloni nezinye izinto.Ngawo-1960s, amasosha ase-US asebenzisa i-high-power synthetic aramid fiber (Kevlar fiber) eyathuthukiswa yi-DuPont ukwenza amavesti angangenwa izinhlamvu anomphumela omuhle ongangenwa izinhlamvu, isisindo esilula nokugqoka ntofontofo.Ekuqaleni kwekhulu lama-21, amasosha ase-US asebenzisa izivikelo zomzimba ze-"Interceptor" ezinomklamo we-modular kanye ne-KM2 yamandla aphezulu we-aramid synthetic fiber njengongqimba oluvikela izinhlamvu endaweni yempi yase-Iraq.Kusukela ekupheleni kweminyaka yawo-1950, i-Chinese People's Liberation Army iye yathuthukisa futhi yahlomisa izivikelo zomzimba ze-FRP ngokulandelana kwazo, izivikelo zomzimba zensimbi ezikhethekile ezinamandla aphezulu, izivikelo zomzimba ezinamandla aphezulu kanye ne-high-modulus polyethylene, kanye nezivikelo zomzimba ze-ceramic.Ngokuthuthuka kwesayensi nobuchwepheshe, amavesti angangenwa izinhlamvu azosebenzisa izinto ezingangenwa izinhlamvu ezisebenza kangcono, ehlise isisindo, athuthukise imiphumela engangenwa izinhlamvu kanye nokunethezeka kokugqoka, aphinde abone ukumodela kwesakhiwo, ukuhlukahluka kanye nokulandelanisa kwesitayela.
