Munzvimbo dzakasarudzika dzepasi rose dzanhasi, ndiro dzeBulletproof (kana mataira ekudzivirira bullet) dzinokosheswa zvikuru nevanhu, asi pamusika we "bulletproof plate" dzakawanda, musiyano wekushanda wakakurawo, zvichienderana nezvinhu, maitiro uye mamwe ma "bulletproof plate" akajairika anogona kukamurwa muzvikamu zvitatu, zvinoti "steel bulletproof plate", "polyethylene PE bulletproof plate" uye "ceramic bulletproof plate", marudzi matatu e "bulletproof plate" rimwe nerimwe rine zvakanakira nezvakaipira. Sarudzo yacho inodawo kufungwa zvakadzama. Sarudza "bulletproof plate", unofanirwa kutarisa pazvinhu zvitatu zvinoti huremu, mutengo uye kugona kwe "bulletproof" (kureva "level bulletproof proof"), nhasi tiri kubva muzvikamu zvitatu izvi zvemhando nhatu dze "bulletproof plate" kuongorora nekuenzanisa.
1. Ndiro yesimbi isingapindi mabara
Mapureti esimbi asingapindi mabara ave achishandiswa kubvira Hondo Yenyika II uye akatonga musika usingapindi mabara makumi emakore apfuura. Asi mushure mekugadzirwa kwepureti ye polyethylene PE isingapindi mabara uye pureti yeceramic isingapindi mabara, pureti yesimbi isingapindi mabara yakatsiviwa zvishoma nezvishoma. Achiri kushandiswa nanhasi, asi muhuwandu hushoma.
Kana tichienzanisa neplate itsva isingapindi mabara, plate yesimbi isingapindi mabara iri nyore kutyoka mushure mekupfurwa, izvo zvinozokonzera kukuvara kwemuviri wemunhu. Kana tichienzanisa nezvimwe zvinhu zviviri, plate yesimbi isingapindi mabara ine dziviriro yakafanana inorema, inoshandisa simba rakawanda uye inoderedza kuchinjika kweanoipfeka.
Kunyangwe ndiro yesimbi isingapindi mabara iriyo mutengo wakaderera pane matatu akaiswa, asi zvakazara, haikurudzirwi sesarudzo yekutanga.
2. Plate yepolyethylene PE inodzivirira mabara
Polyethylene PE rudzi rutsva rwezvinhu zvinopisa. Plate yepolyethylene PE inogadzirwa nekubatanidza fibers dzepolyethylene dzine huremu hwakanyanya pabhodhi repolyethylene rakakora. Rinochekwa kuita chimiro, roiswa muchimiro, uye rodzvanywa pasi pekupisa kwakanyanya uye kumanikidzwa kuti riwane plate yakasimba yezvombo inonamira. Polyethylene "inonamira" kubara nekunyungudutsa polyethylene nekuda kwekukweshana kunokonzerwa nekutenderera kwebara. Kana kutenderera kwamira, hapana kupisa kunogadzirwa, uye polyethylene inotonhorera uye inooma zvakare.
Hunhu hweplate ye polyethylene PE inodzivirira mabara kazhinji inenge 1 kusvika 1.5kg, yakareruka kupfuura plate yesimbi inodzivirira mabara uye plate yeceramic inodzivirira mabara. Zvisinei, nekuda kwekusakwana kwezvinhu zviripo pari zvino, plate yePE yakachena inogona kuwana dziviriro yepamusoro yeNIJ III, isingakwanisi kudzivirira kubva kumabara anobaya pfuti uye mabara ane simba, uye mutengo wakakwira wepolyethylene PE, mutengo wayo unowanzo kudhura 200% kusvika 300% kupfuura plate yeceramic inodzivirira mabara, haisi sarudzo yakanaka.
3. Ndiro yeceramic isingapindi mabara
Zvishandiso zveCeramic zvinogona kushandisa zvinhu zvakasiyana-siyana, zvakajairika ialumina, silicon carbide uye boron carbide. Zvishandiso zveCeramic hazvipindi mabara nekuda kwekuomarara kwazvo, simba, uye kusagadzikana kwemakemikari munzvimbo dzakawanda. Zviri nani pane simbi nekuti zvinhu zvesimbi zvinogadzira purasitiki uye zvinotora simba kana zvichirwisa kukanganiswa kwemusoro wehondo, nepo ceramic isingawanzo gadzira purasitiki uye musoro wehondo uchave wakaoma kana kutotyoka nekuda kwesimba rayo guru uye hunhu hwekuoma. Zvishandiso zveCeramic zvisingapindi mabara uye fiber composite plate ine simba guru, layer isingapindi mabara uye ceramic layer inodonha, kana ceramic layer ichidonha nekukurumidza, ceramic layer ichipwanyika kana kutsemuka uye kusvika panzvimbo yekukanganisa sepakati penzvimbo yakapoteredza kuti ishandise simba rakawanda remuviri weprojectile, ipapo high modulus fiber composite plate kuti iwedzere kushandisa simba rakasara remuviri weprojectile. Saka, kushandiswa kwezvishandiso zveCeramic zvepamusoro muzvishandiso zvezvombo kunokwezva zvikuru uye kwave kushandiswa zvakanyanya kudzivirira zvombo zvemuviri, mota, ndege nezvimwe zvishandiso.
Dambudziko replate yeceramic nderekuti mushure mekurohwa, nzvimbo yekurovera haigone kudzivirira bara zvakare. Asi ikozvino plate yeceramic yakareruka uye yakasimba kupfuura kare, vamwe vagadziri vanogona kutoita kuti huremu hwayo huve pedyo neplate yePE, uye kuburikidza nekushandisa zvinhu zvakasiyana-siyana vanogonawo kusangana nehuremu, mutengo nezvimwe zvinodiwa.
Nehukuru hwakaenzana nedziviriro yakafanana, ndiro yeceramic inodzivirira mabara yakareruka kupfuura ndiro yesimbi inodzivirira mabara, uye mutengo wakaderera pane ndiro yepolyethylene PE uye kunyange ukobvu hwayo hunogona kutetepa.
Kazhinji, ndiro yesimbi inopindwa nemabara iri nyore uye ine mutengo wakaderera, asi huremu hwayo hwakanyanya kukura, uye zviri nyore kukonzera kukuvara kwechipiri kune mushandisi; Kunyangwe ndiro ye polyethylene PE isina mabara iri yakareruka, asi kugona kwayo kudzivirira mabara kwakaderera, uye mutengo wayo unodhura; Tichienzanisa, ndiro ye ceramic inopindwa nemabara haisi yemhando yechiedza chete, mutengo wakaderera, uye kugona kwayo kudzivirira mabara kwakanaka; mashandiro e silicon carbide ceramic bulletproof plate ari pamusoro pe alumina plate, ndiyo sarudzo yakanakisisa yeplate ye bulletproof.
