Emkhakheni wokuvikela wesimanje, ngokuthuthukiswa okuqhubekayo kwamandla ezikhali, izimfuneko zezinto ezingangenwa izinhlamvu ziya ngokuya ziba nzima.I-silicon carbide, into ebonakala ivamile kodwa inamandla amakhulu, kancane kancane ivela njengentandokazi entsha embonini yokuvikela izinhlamvu. Namuhla, sizokwembula iveyili engaqondakali ye-silicon carbide bulletproof.
1. Kwembula isimiso sokuvikela izinhlamvu
Umnyombo wokuvikela izikhali usekudleni amandla ama-projectiles, ukuwanciphisa kuze kube yilapho elahlekelwa ingozi yawo. Izinto zensimbi zendabuko zithembele ekuguquguqukeni kwepulasitiki ukuze zimunce amandla, kuyilapho izinto ze-ceramic zifinyelela lo mgomo ngenqubo eyingqayizivele yokuchotshozwa okuncane. Sithatha izitsha zobumba ze-silicon carbide bulletproof njengesibonelo, lapho i-projectile ishayisa, iprojectile iqala ibe buthuntu khona manjalo endaweni yomthelela, futhi indawo yobumba iyachotshozwa ukuze yakhe indawo ehlukene kabili. Le nqubo ifana nokunikeza i-projectile "isando" futhi iqale imunce amandla; Khona-ke, i-projectile eboshiwe yaqhubeka iqhubekela phambili, igugule indawo ehlukanisiwe futhi yenza ungqimba oluqhubekayo lwezingcezu ze-ceramic; Ekugcineni, i-ceramic fractures ngaphansi kwengcindezi eqinile, futhi i-backplate iqala ukonakala. Amandla asele adonswa ngokuphelele ngokuguqulwa kwempahla ye-backplate.
2. Kungani i-silicon carbide ingaba yi-bulletproof?
I-Silicon carbide iyinhlanganisela ikakhulukazi eyakhiwe ngamabhondi e-covalent, futhi amabhondi ayo e-Si-C angagcina amandla aphezulu emazingeni okushisa aphezulu. Lesi sakhiwo esiyingqayizivele sinikeza i-silicon carbide ceramics enezakhiwo eziningi ezinhle kakhulu. Inobunzima obuphakeme kakhulu, okwesibili ngemuva kwedayimane, i-cubic boron nitride, ne-boron carbide phakathi kwezinto ezivamile. Kufana neqhawe eligqoke isivikelo esiqinile, elikwazi ukumelana ngokuqinile nomthelela we-projectile; Ngesikhathi esifanayo, inokuminyana okuphansi futhi ilula ngesisindo uma yenziwe imishini yokuvikela izinhlamvu. Noma ngabe okokulwa komuntu ngamunye noma okuhlonyiswe ezimotweni nasezindizeni, ngeke kube umthwalo owengeziwe, kodwa kunalokho kungathuthukisa ukuhamba kwamayunithi okulwa. Ngaphezu kwalokho, i-silicon carbide iphinde ibe nokusimama okuhle kokushisa kanye nokumelana nokugqwala kwamakhemikhali, futhi ingadlala indima yokuvikela izinhlamvu ngokuzinzile ezindaweni ezahlukahlukene eziyinkimbinkimbi.
I-3, Izinzuzo eziyingqayizivele zokusabela kwe-silicon carbide ezingxenyeni ezenziwe ngokwezifiso
Enqubweni yokulungiselela i-silicon carbide ceramics, i-reaction sintered silicon carbide (RBSiC) iyagqama, ifaneleka ngokukhethekile ukukhiqizwa kwengxenye eyenziwe ngokwezifiso, ngenxa yalezi zizathu ezilandelayo:
1. Ukuminyana okuphezulu namandla aphezulu: Ngaphansi kwezimo zokushisa eziphezulu, ikhabhoni yamahhala ihlangana ne-silicon enguketshezi ukuze kukhiqizwe amakristalu amasha e-silicon carbide. Ngesikhathi esifanayo, i-silicon yamahhala ingena futhi igcwalise ama-pores, ikhulise kakhulu ukuminyana kwezinto, icishe isondele ekugqineni kwethiyori. Lokhu akugcini nje ngokunikeza impahla amandla amahle kakhulu okucindezela nokugoba, kodwa futhi kunikeza ukumelana okuhle kokugqoka, okungamelana nengcindezi ephezulu kanye nezimo eziphezulu zomthelela, ukuhlangabezana nezidingo eziqinile zezingxenye ezenziwe ngokwezifiso zamandla nokuqina.
2. Isakhiwo esincane esilawulekayo: Inqubo yokusabela i-sintering ingalawula ngokunembile ukukhula kwezinhlamvu, yenze ama-microstructures amancane nafanayo. Lesi sakhiwo esihle se-microstructure sithuthukisa futhi izici zemishini yento ephathekayo, iyenze ihlale izinzile futhi ingajwayele ukuqhekeka noma ukulimala lapho ibhekene nokucindezeleka okuhlukahlukene okuyinkimbinkimbi, ihlinzeka isiqinisekiso esiqinile sokuthembeka kwezingxenye ezenziwe ngokwezifiso.
3. Ukunemba okuphezulu kwe-dimensional: Ngesikhathi senqubo yokuminyana, izinguquko zobukhulu be-action sintered silicon carbide zincane, okubalulekile ezingxenyeni ezingokwezifiso. Kungakhathaliseki ukuthi ipulaki elilodwa lesosha elingenanhlamvu elinezimo eziyinkimbinkimbi noma ingxenye ekhethekile yokuvikela imoto enezidingo zosayizi oqinile, angenziwa ngokunembile ukuze kuqinisekiswe ukuhambisana okuphelele nezisetshenziswa.
4. Ukuzinza okuhle kwamakhemikhali: I-Reaction sintered silicon carbide cishe ayinazo izimbotshana ezivulekile, okwenza kube nzima ukuthi umoya-mpilo nezinto ezibolayo zingene ngaphakathi kwempahla, ngaleyo ndlela ibe ne-oxidation eqine kakhulu kanye nokungagqwala. Lokhu kusho ukuthi imikhiqizo eyenziwe ngokwezifiso ye-silicon carbide bulletproof isengagcina ukusebenza okuzinzile, inwebe impilo yesevisi, futhi yehlise izindleko zokuyilungisa endaweni enzima yemvelo noma yamakhemikhali isikhathi eside.
4, Inkambu yesicelo se-silicon carbide bulletproof
Ngokusebenza kwayo okuhle kakhulu, izinto ze-silicon carbide bulletproof zisetshenziswe kabanzi emikhakheni eminingi:
1. Imishini yomuntu ngamunye: i-silicon carbide bulletproof vest lining, i-bulletproof helmet, njll., ihlinzeka amasosha ngesivikelo esingasindi nesiphezulu, esiwavumela ukuthi alwe ngendlela eguquguqukayo enkundleni yempi kuyilapho enokuvikela okuthembekile kokuphepha.
2. Izimoto ezikhethekile: njengezimoto ezihlomile, izimoto zokuthutha imali, izimoto zokulwa nobuphekula kanye nezimoto zokulawula izibhelu, njll., zifakwe izikhali ze-silicon carbide ceramic ezingxenyeni ezibalulekile, ezingamelana ngokuphumelelayo nokuhlaselwa kwezikhali ezihlukahlukene futhi zivikele ukuphepha kwabasebenzi kanye nezinto ezibalulekile ngaphakathi kwemoto.
3. I-Aerospace: Izinto ze-silicon carbide bulletproof zisetshenziswa ezindizeni ezinophephela emhlane ezihlomile nezinye izindiza ukuze zehlise isisindo sazo, zithuthukise ukusebenza kwendiza, futhi zithuthukise ikhono lazo lokuvikela emlilweni wesitha, kuqinisekiswe ukuphepha endizeni.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, izinto ze-silicon carbide bulletproof zizoqhubeka nokuthuthuka futhi zisungule, kwakhiwe umugqa wokuzivikela oqinile wokuvikela ukuphepha. Uma unentshisekelo ezingxenyeni ezingokwezifiso ze-reaction sintered silicon carbide ceramics, sicela ukhululeke ukuxhumana nathi.
