Kodi pali kusiyana pakati pa ma bulletproof vests ndi ma suti otsimikizira?Popeza zovala zoteteza zipolopolo zimatha kuteteza zipolopolo, kodi sikofunikira kwambiri kupewa kubaya?Kusiyana kwakukulu pakati pawo ndi momwe amagwirira ntchito, imodzi ndi yopanda zipolopolo ndipo inayo ndi umboni wa mpeni.Zakale zimagwiritsidwa ntchito makamaka poteteza zipolopolo, pamene zotsirizirazi zimagwiritsidwa ntchito makamaka poteteza mipeni ndi zida zosongoka.

Zovala za bulletproof, zomwe zimatchedwanso bulletproof vests, bulletproof vests, bulletproof vests, bulletproof suits, chitetezo chamunthu payekha, ndi zina zotere, zimagwiritsidwa ntchito kuteteza thupi la munthu ku mitu ya zipolopolo kapena zidutswa.Chovala chotchinga zipolopolo chimakhala ndi magawo awiri: jekete ndi wosanjikiza woteteza zipolopolo.Zophimba nthawi zambiri zimapangidwa ndi nsalu za ulusi wamankhwala.Zosanjikiza zipolopolo zimapangidwa ndi zitsulo (chitsulo chapadera, aloyi ya aluminiyamu, titaniyamu aloyi), mapepala a ceramic (corundum, boron carbide, silicon carbide, alumina), fiberglass, nayiloni, Kevlar, ultra-high molecular weight polyethylene fiber, zipangizo zotetezera madzi, ndi zipangizo zina, kupanga dongosolo limodzi kapena gulu chitetezo.Chosanjikiza chotchinga zipolopolo chimatha kuyamwa mphamvu ya kinetic ya mitu ya zipolopolo kapena zidutswa, ndipo chimakhala ndi chitetezo chachikulu pamitu kapena tizidutswa ta zipolopolo zothamanga kwambiri.Ikhoza kuchepetsa kuwonongeka kwa chifuwa ndi mimba ya thupi la munthu polamulira kupsinjika maganizo kwina.

Zovala za anti kubaya, zomwe zimadziwikanso kuti anti mpeni, zovala za anti mpeni, kapena zovala za anti mpeni, zimakhala ndi ntchito monga kudula mpeni, kudula mpeni, kubaya mpeni, kukwapula kwa zinthu m'mphepete, kukana kuvala, komanso kupewa kuba.Povala zovala zodzitetezera ku mpeni, zimatha kuteteza mwiniwakeyo ku mabala, kukanda, kupukuta, ndi kudulidwa ngati atavala kapena kudulidwa, kudula, kudula, kukwapula, kukwapula, kapena kudula ndi mpeni wakuthwa (tsamba, chinthu chakuthwa, ndi zina zotero).

Makina otetezedwa ndi zipolopolo amavala zoteteza zipolopolo ndi motere: zida zolimba kwambiri komanso zapamwamba zokhala ndi zida zofewa zamtundu wa modulus zimatenga mphamvu yamagetsi yama projectiles kudzera pakusweka kwa ulusi ndi kusintha kwa nsalu.Komabe, mphamvu yopangidwa ndi chida chobaya ndi kumeta ubweya wa nkhawa, ndi malangizo a mphamvu ya perpendicular kwa fiber, ndipo mphamvu ya nsonga ya nsonga ndiyokwera kwambiri kuposa ya chipolopolo, kotero kuti fiber yakuthupi imakhala yotsutsa kwambiri. ofukula kukameta ubweya kupsinjika.

Mfundo yotsutsana ndi stab ya zovala zotsutsana ndi kubaya: Kapangidwe kapadera kamene kamaphatikiziridwa ndi ntchito yabwino kwambiri ya ulusi wamphamvu kwambiri kumapangitsa kuti ikhale ndi ntchito monga anti cutting, anti cutting, ndi anti stab.

Chotero pali kusiyana kwakukulu pakati pa ziŵirizi, ndipo m’moyo weniweni, munthu angasankhe kugwiritsira ntchito zovala zosaloŵerera zipolopolo kapena zovala zotsimikizira kubaya malinga ndi mkhalidwe weniweniwo.
