Ngezakhiwo zayo eziyingqayizivele, i-99% ye-alumina ceramic ikhombisa amandla amakhulu okusetshenziswa emkhakheni wokuvikela izinhlamvu, futhi isibe ukukhetha okubalulekile phakathi kwezixazululo ezilula zokuvikela izinhlamvu.
I-99% alumina ceramicinobulukhuni obuphezulu kakhulu kanye namandla okucindezela. Ubumsulwa bayo be-alumina buphezulu kakhulu, futhi ubuningi buphezulu kakhulu. Cishe azikho izimbobo noma ukungcola ngaphakathi. Ubulukhuni bungafinyelela ngaphezu kwe-HRA90, futhi amandla okucindezela adlula i-3000 MPa. Lapho inhlamvu ishaya ngesivinini esikhulu, ubuso be-ceramic obuqinile bungacindezela, bushintshe, noma buphule ikhanda lenhlamvu ngokushesha. Ngesikhathi esifanayo, isakhiwo sekristalu se-ceramic esinobulukhuni obukhulu singasabalalisa ngokushesha amandla okushaya futhi sidle amandla e-kinetic enhlamvu, sivimbele ikhanda lenhlamvu ukuthi lingene epuletini elingenamabhulethi, ngaleyo ndlela linikeze isikhathi sesendlalelo esilandelayo se-buffer sokumunca amandla.
Ngokuphathelene nomklamo olula, i-99% ye-alumina ceramics inezinzuzo ezibalulekile. Uma kuqhathaniswa nezinto zensimbi zendabuko ezingangenwa yizinhlamvu (njengezingcwecwe zensimbi), ubuningi bayo bungu-3.9-4.0g/cm³ kuphela, okungaphansi kwengxenye yensimbi. Ngaphansi kwezinga elifanayo lokuvikela, isisindo sezikhali ezingangenwa yizinhlamvu ezisebenzisa i-99% ye-alumina ceramics singancishiswa ngo-40%-60%, okubalulekile ezimweni ezizwela isisindo njengemishini yokuzivikela yomuntu ngamunye kanye nezikhali zemoto. Lokhu kunganciphisa umthwalo kubasebenzisi futhi kuthuthukise ukuhamba.
Ezisetshenzisweni ezisebenzayo, ama-ceramic e-alumina angu-99% avame ukuhlanganiswa nezinto ezihlanganisiwe zefayibha (njenge-aramid, i-polyethylene enesisindo sama-molecule esiphezulu kakhulu) ukuze kwakheke isakhiwo esihlanganisiwe esingavimbeli bullet. Isendlalelo se-ceramic sisebenza njengomugqa wokuqala wokuzivikela, obangela ukuphula ikhanda lenhlamvu nokuhlakaza amandla okushaya. Isendlalelo sefayibha simunca amandla asele ngokuguquguquka. Ukusebenzisana kwalezi zingxenye ezimbili kungathuthukisa kakhulu umphumela wokuvikela jikelele. Isibonelo, ezifakweni ezingavimbeli bullet, amashidi e-ceramic e-alumina angu-99%, ngemva kokusika nokuhlanganisa okunembile, ahlanganiswa ne-backplate yefayibha. Angamelana ngempumelelo nomthelela wezinhlamvu zesibhamu nezibhamu futhi ahlangabezane nezindinganiso zokuvikela ze-NIJ III nangaphezulu.
Ngaphezu kwalokho, ukuzinza kwamakhemikhali kanye nokumelana nokushisa okuphezulu kwe-99% alumina ceramics nakho kunikeza isiqinisekiso sokusetshenziswa kwazo ekusetshenzisweni okuvikela izinhlamvu. Ayigugi kalula yimvelo futhi ingagcina ukusebenza okuzinzile ngisho nasezimweni eziyinkimbinkimbi njengomswakama kanye namazinga okushisa aphezulu. Ngaphezu kwalokho, lapho inhlamvu ishaya futhi ikhiqiza amazinga okushisa aphezulu endawo (ngamazinga okushisa asheshayo afinyelela amakhulu amaningana degrees Celsius), ngeke iguge ngenxa yokushisa okuphezulu, ngaleyo ndlela ingathinti umphumela wokuvikela futhi iqinisekise ukuthembeka kwesikhathi eside kwemishini evikela izinhlamvu.
