Esimweni sanamuhla esikhethekile samazwe ngamazwe, ipuleti le-Bulletproof (noma amathayela angangenwa izinhlamvu) aziswa kakhulu abantu, kodwa emakethe yepuleti elingangenwa izinhlamvu linezinto eziningi, umehluko wokusebenza mkhulu kakhulu futhi, ngokuya ngezinto, inqubo kanye nezinye ipuleti elivamile elingangenwa izinhlamvu zingahlukaniswa. ngezigaba ezintathu, okuyipuleti lensimbi elingangenwa nhlamvu, ipuleti le-polyethylene PE le-bulletproof kanye nepuleti le-ceramic le-bulletproof, izinhlobo ezintathu zepuleti elingangenwa izinhlamvu ngayinye inezinzuzo kanye nebubi, Ukukhetha kudinga ukucatshangelwa okuphelele.Khetha ipuleti elingangenwa izinhlamvu, kudingeka ugxile ezicini ezintathu okuyisisindo, intengo nekhono lokuvikela izinhlamvu (okungukuthi izinga lokuvikela izinhlamvu), namuhla siphuma kulezi zici ezintathu zezinhlobo ezintathu zokuhlaziywa kwepuleti elingangenwa izinhlamvu kanye nokuqhathanisa.
1. Ipuleti lensimbi elingangenwa izinhlamvu
Ipuleti lensimbi elingangenwa izinhlamvu belilokhu lisetshenziswa kusukela ngeMpi Yezwe II futhi lalibusa imakethe yezinhlamvu emashumini eminyaka edlule.Kodwa ngemva kokuthuthukiswa kwepuleti le-polyethylene PE le-bulletproof plate kanye nepuleti le-ceramic le-bulletproof, ipuleti lensimbi le-bulletproof lashintshwa kancane kancane.Zisasetshenziswa nanamuhla, kodwa ngamanani amancane.
Uma kuqhathaniswa nepuleti elisha elingangenwa izinhlamvu, ipuleti lensimbi linganqamuki kalula ngemva kokudutshulwa, okuzodala umonakalo wesibili emzimbeni womuntu.Uma kuqhathaniswa nezinye izinto ezimbili, ipuleti lensimbi elingangenwa ngamachashazi elinezinga elifanayo lokuvikela lisinda kakhulu, lidla amandla amaningi futhi linciphisa ukuguquguquka komuntu oligqokile.
Nakuba ipuleti lensimbi le-bulletproof liyinani eliphansi kakhulu ekufakweni okuthathu, kodwa sekukonke, akunconywa njengokukhetha kokuqala.
2. Ipuleti le-polyethylene PE le-bulletproof
I-Polyethylene PE iwuhlobo olusha lwempahla ye-thermoplastic.Ipuleti le-polyethylene PE le-bulletproof lakhiwa ngokuhlanganisa imicu ye-polyethylene enesisindo esiphezulu se-molecular unidirectional ebhodini le-polyethylene elinokuminyana okuphezulu.Isikwa ibe yisimo, ifakwe esikhunjeni, futhi icindezelwe ngaphansi kwezinga lokushisa eliphezulu nokucindezela ukuze kutholwe ipuleti lezikhali eliqinile le-viscous.I-polyethylene “inamathela” kunhlamvu ngokuncibilikisa i-polyethylene ngenxa yokungqubuzana okubangelwa ukuzungezisa kwenhlamvu.Lapho ukujikeleza kuma, akukho ukushisa okukhiqizwayo, futhi i-polyethylene iyaphola futhi iqinise kabusha.
Izinga le-polyethylene PE bulletproof plate ngokuvamile licishe libe ngu-1 ukuya ku-1.5kg, lilula kakhulu kunepuleti lensimbi elingangenwa izinhlamvu kanye nepuleti le-ceramic le-bulletproof.Kodwa-ke, ngenxa yokulinganiselwa kwenqubo yezinto ezibonakalayo zamanje, ipuleti le-PE elihlanzekile lingafinyelela izinga eliphakeme kakhulu lokuvikela le-NIJ III, elingakwazi ukuzivikela ngokumelene nezinhlamvu zokubhoboza izibhamu kanye nezinhlamvu ezinamandla kakhulu, kanye nezindleko eziphezulu ze-polyethylene PE, intengo yayo ngokuvamile i-200. I-% kuya ku-300% ibiza kakhulu kunepuleti le-ceramic bulletproof, akuyona inketho enhle.
3. Ipuleti le-Ceramic bulletproof
Ukufakwa kwe-Ceramic kungasebenzisa izinto ezihlukahlukene, okuvame kakhulu i-alumina, i-silicon carbide ne-boron carbide.Ama-Ceramics awakwazi ukumelana nezinhlamvu ngenxa yokuqina kwawo okukhethekile, amandla, kanye nokungangeni kwamakhemikhali ezindaweni eziningi.Kungcono kunensimbi ngoba izinto zensimbi zizokhiqiza ukuguquguquka kwepulasitiki futhi zimunce amandla lapho zimelana nomthelela we-warhead, kuyilapho i-ceramic ngeke ikhiqize ukuguqulwa kwepulasitiki futhi i-warhead izoba buthuntu noma iphuke ngenxa yamandla ayo aphezulu kanye nezici zokuqina.I-ceramic engenanhlamvu kanye namandla aphezulu aphezulu i-modulus fiber composite plate bulletproof layer, lapho i-projectile enesivinini esikhulu kanye nongqimba lwe-ceramic kungqubuzana, ukuhlukana kwesendlalelo se-ceramic noma ukuqhekeka kanye nendawo yomthelela njengendawo ephakathi nendawo ukuze kusetshenziswe amandla amaningi we-ceramic. umzimba we-projectile, bese kuba ipuleti eliyinhlanganisela ye-modulus fiber ephezulu ukuze liqhubeke nokusebenzisa amandla ayinsalela omzimba we-projectile.Ngakho-ke, ukusetshenziswa kwe-ceramics ethuthukisiwe ezinhlelweni zempi kuyathandeka kakhulu futhi sekuyisivikelo esisetshenziswa kakhulu sezivikelo zomzimba, izimoto, izindiza kanye nezinye izinto zokusebenza.
Okubi kwepuleti le-ceramic ukuthi ngemuva kokushaywa, iphuzu lomthelela alikwazi ukuvikela inhlamvu futhi.Kodwa manje ipuleti ye-ceramic ilula futhi inamandla kunangaphambili, abanye abakhiqizi bangakwazi ngisho nokwenza isisindo saso sisondele ku-PE plate, futhi ngokusebenzisa izinto ezihlukahlukene bangahlangabezana nesisindo, intengo nezinye izidingo.
Kusayizi ofanayo onezinga elifanayo lokuvikela, ipuleti le-ceramic le-bulletproof lilula kunepuleti lensimbi le-bulletproof, futhi intengo iphansi kunepuleti le-polyethylene PE futhi ngisho nobukhulu bungaba buncane.
Ngokuvamile, ipuleti lensimbi le-bulletproof lilula futhi liphansi, kodwa isisindo sikhulu kakhulu, futhi kulula ukubangela umonakalo wesibili kumsebenzisi;Nakuba ipuleti le-polyethylene PE bulletproof lilula, kodwa ikhono lokuvikela izinhlamvu limpofu, futhi intengo iyabiza;Uma kuqhathaniswa, ipuleti le-ceramic le-bulletproof aligcini nje ngekhwalithi yokukhanya, intengo ephansi, nekhono lokuvikela izinhlamvu lihle kakhulu;Ukusebenza kwepuleti le-silicon carbide ceramic bulletproof kungaphezulu kwepuleti ye-alumina, ukukhetha okungcono kakhulu kwepuleti le-bulletproof.
