Emkhakheni wokuvikelwa kwesimanje, ngokuthuthukiswa okuqhubekayo kwamandla ezikhali, izidingo zezinto ezingangenwa yizinhlamvu ziya ngokuya ziba nzima.I-silicon carbide, into ebonakala ijwayelekile kodwa enamandla kakhulu, kancane kancane ivele njengeyintandokazi entsha embonini yokuvikela izinhlamvu. Namuhla, sizokwembula isihenqo esiyimfihlakalo sokuvikela izinhlamvu ze-silicon carbide.
1, Ukwembula isimiso sokuvikela izinhlamvu
Ingqikithi yokuvikelwa kwezikhali itholakala ekudleni amandla ezinto eziqoshwe phansi, zinciphise ijubane lazo zize zilahlekelwe yingozi yazo. Izinto zensimbi zendabuko zithembele ekuguqulweni kwepulasitiki ukuze zimunce amandla, kuyilapho izinto zobumba zifeza lo mgomo ngenqubo eyingqayizivele yokuchoboza okuncane. Uma sithatha izinto zobumba ezivikela izinhlamvu ze-silicon carbide njengesibonelo, lapho into eqoshwe phansi ishaya, into eqoshwe phansi iqala ukuba buthuntu ngokushesha ebusweni bokushayisana, bese indawo yobumba ichotshozwa ukuze yakhe indawo eqinile eqotshwe phansi. Le nqubo ifana nokunikeza into eqoshwe phansi “isando” bese imunca amandla ekuqaleni; Ngemuva kwalokho, into eqoshwe phansi iyaqhubeka nokuqhubekela phambili, igugula indawo eqotshwe phansi futhi yakha ungqimba oluqhubekayo lwezingcezu zobumba; Ekugcineni, izinto zobumba ziyaphuka ngaphansi kokucindezeleka kokudonsa, futhi i-backplate iqala ukonakala. Amandla asele amuncwa ngokuphelele ukuguquguquka kwezinto eziqoshwe phansi.
2. Kungani i-silicon carbide ingaba yi-bulletproof?
I-silicon carbide iyinhlanganisela eyakhiwe kakhulu ngamabhondi e-covalent, futhi amabhondi ayo e-Si-C angagcina amandla aphezulu emazingeni okushisa aphezulu. Lesi sakhiwo esiyingqayizivele sinikeza i-silicon carbide ceramics izakhiwo eziningi ezinhle kakhulu. Inobulukhuni obukhulu kakhulu, ilandela idayimane, i-cubic boron nitride, kanye ne-boron carbide phakathi kwezinto ezivamile. Ifana neqhawe eligqoke isivikelo esiqinile, elikwazi ukumelana ngokuqinile nokushaywa yi-projectile; Ngesikhathi esifanayo, inobukhulu obuphansi futhi inesisindo esilula uma yenziwe imishini yokuzivikela ezinhlamvini. Kungakhathaliseki ukuthi ingeyempi ngayinye noma ifakwe ezimotweni nasezindizeni, ngeke ibe umthwalo owengeziwe, kodwa esikhundleni salokho ingathuthukisa ukuhamba kwamayunithi okulwa. Ngaphezu kwalokho, i-silicon carbide nayo inokuqina okuhle kokushisa kanye nokumelana nokugqwala kwamakhemikhali, futhi ingadlala indima eqinile yokuvikela ezinhlamvini ezindaweni ezahlukahlukene eziyinkimbinkimbi.
3, Izinzuzo eziyingqayizivele ze-silicon carbide e-reaction sintered ezingxenyeni ezenziwe ngezifiso
Enqubweni yokulungiselela i-silicon carbide ceramics, i-reaction sintered silicon carbide (RBSiC) iyagqama, ifaneleka kakhulu ekukhiqizweni kwezingxenye okwenziwe ngokwezifiso, ngenxa yezizathu ezilandelayo:
1. Ubuningi obukhulu kanye namandla aphezulu: Ngaphansi kwezimo zokushisa okuphezulu, ikhabhoni yamahhala isabela ne-silicon ewuketshezi ukuze ikhiqize amakristalu amasha e-silicon carbide. Ngesikhathi esifanayo, i-silicon yamahhala ingena futhi igcwalise ama-pores, ikhulisa kakhulu ubuningi bezinto, icishe isondele ekuqineni okungokwemfundiso. Lokhu akugcini nje ngokunika izinto amandla amahle okucindezela nokugoba, kodwa futhi kuyinika ukumelana okuhle kokuguguleka, okungamelana nokucindezela okuphezulu kanye nezimo zomthelela ophezulu, kuhlangatshezwane nezidingo eziqinile zezingxenye ezenzelwe wena ukuze ziqine futhi ziqine.
2. Isakhiwo esincane esilawulekayo: Inqubo yokususa ukusabela ingalawula ngokunembile ukukhula kwezinhlayiya, yakha izakhiwo ezincane nezifanayo. Lesi sakhiwo esincane esincane sithuthukisa kakhulu izakhiwo zemishini zento, okwenza ukuthi ihlale izinzile futhi ingaqhekeki noma yonakale uma ibhekene nokucindezeleka okuhlukahlukene okuyinkimbinkimbi, okunikeza isiqinisekiso esiqinile sokuthembeka kwezingxenye ezenziwe ngokwezifiso.
3. Ukunemba okuphezulu kobukhulu: Ngesikhathi senqubo yokuqina, izinguquko zobukhulu be-response sintered silicon carbide zincane kakhulu, okuyinto ebalulekile ezingxenyeni ezenziwe ngokwezifiso. Kungakhathaliseki ukuthi ipulaki elilodwa elivikela izinhlamvu zamasosha elinezimo eziyinkimbinkimbi noma ingxenye ekhethekile yokuvikela imoto enezidingo zosayizi eziqinile, zingakhiqizwa ngokunembile ukuqinisekisa ukuhambisana okuphelele nemishini.
4. Ukuqina okuhle kwamakhemikhali: I-silicon carbide e-Reaction sintered ayinazo izimbobo ezivulekile, okwenza kube nzima ukuthi umoya-mpilo nezinto ezibolayo zingene ngaphakathi kwezinto, ngaleyo ndlela zibe nokumelana okukhulu kwe-oxidation kanye nokugqwala. Lokhu kusho ukuthi imikhiqizo ye-silicon carbide eyenziwe ngokwezifiso isengagcina ukusebenza okuzinzile, yandise impilo yesevisi, futhi inciphise izindleko zokulungisa ezindaweni zemvelo noma zamakhemikhali ezinzima isikhathi eside.
4, insimu yesicelo esingangenwa yi-silicon carbide
Ngenxa yokusebenza kwayo okuhle kakhulu, izinto zokuvikela izinhlamvu ze-silicon carbide zisetshenziswe kabanzi emikhakheni eminingi:
1. Imishini ngayinye: ulwelwesi lwevesti elingangenwa yizinhlamvu lwe-silicon carbide, isigqoko esingangenwa yizinhlamvu, njll., sinikeza amasosha isivikelo esilula nesiphezulu, esiwavumela ukuthi alwe kalula enkundleni yempi ngenkathi enesivikelo sokuphepha esithembekile.
2. Izimoto ezikhethekile: njengezimoto ezihlomile, izimoto zokuthutha imali, izimoto zokulwa nobuphekula kanye nezokulawula udlame, njll., zihlonyiswe ngezikhali ze-silicon carbide ceramic ezingxenyeni ezibalulekile, ezingamelana ngempumelelo nokuhlaselwa kwezikhali ezahlukahlukene futhi zivikele ukuphepha kwabasebenzi nezinto ezibalulekile ngaphakathi emotweni.
3. Izindiza: Izinto ezingangenwa yizinhlamvu ze-silicon carbide zisetshenziswa ezindizeni ezinophephela emhlane nakwezinye izindiza ukuze kuncishiswe isisindo sazo, kuthuthukiswe ukusebenza kwezindiza, futhi kuthuthukiswe ikhono lazo lokuvikela emlilweni wesitha, kuqinisekiswe ukuphepha kwezindiza.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, izinto ezivikela izinhlamvu ze-silicon carbide zizoqhubeka nokuthuthukisa nokusungula izinto ezintsha, zakha umugqa wokuzivikela oqinile wokuvikela ukuphepha. Uma unesithakazelo ezingxenyeni ezenziwe ngokwezifiso ze-reaction sintered silicon carbide ceramics, sicela ukhululeke ukuxhumana nathi.
