Iiseramics ze-silicon carbide ze-Sintered kunye ne-silicon carbide ceramic uthotho lwemveliso yeembumbulu

I-Sintered SiC Ceramics: Izinto eziluncedo zeSiC Ceramic Ballistic Products

Iimveliso ze-silicon carbide ceramic bulletproofziya zithandwa ngakumbi kwinkalo yokhuselo lomntu kunye nomkhosi ngenxa yokusebenza kwazo okugqwesileyo kunye nokusebenza kwazo. Ezi zeramics zinomxholo we-SiC ≥99% kunye nobunzima (HV0.5) ≥2600, okwenza kube yizinto ezikhethiweyo kwizicelo ze-ballistic ezifana ne-bulletproof vests kunye nezixhobo zokukhusela iitanki kunye nezithuthi ezixhobileyo.

Imveliso ephambili yolu luhlu yi-silicon carbide ceramic bulletproof sheet. Ubuninzi bayo obuphantsi kunye nobunzima obulula buyenza ifaneleke kakhulu kwisixhobo sokukhusela iimbumbulu zejoni ngalinye, ngakumbi njengolwelwe lwangaphakathi lweevesti ezikhusela iimbumbulu. Ngapha koko, ibonelela ngeenzuzo ezibalulekileyo malunga nokuqina, amandla kunye nokuzinza kwe-thermal.

I-silicon carbide (i-SiC) i-ceramics inezakhiwo ezimbini ze-crystal, i-cubic β-SiC kunye ne-hexagonal α-SiC. Ezi ceramics zineebhondi eziqinileyo eziqinileyo, iipropathi ezingcono zoomatshini, ukuxhathisa kwe-oxidation, ukuxhathisa ukunxiba kunye ne-coefficient ephantsi ye-friction kunezinye ii-ceramics ezifana ne-alumina kunye ne-boron carbide. Ukuqhuba kwabo okuphezulu kwe-thermal, i-coefficient encinci yokwandiswa kwe-thermal, kunye nokuchasana okugqwesileyo kumothuko we-thermal kunye nokubola kweekhemikhali kuqhubela phambili usetyenziso lwabo olubanzi.

Umgaqo we-bulletproof we-silicon carbide ceramics usekukwazini kwayo ukutshabalalisa kunye nokufunxa amandla embumbulu. Ngelixa izixhobo zobunjineli zemveli zifunxa amandla ngokuguqulwa kweplastiki, izixhobo ze-ceramic, kubandakanya i-silicon carbide, zenza njalo ngee-microfractures.

Inkqubo yokufunxa amandla e-silicon carbide bulletproof ceramics inokwahlulwa ibe ngamanqanaba amathathu. Ngethuba lesigaba sokuqala sempembelelo, i-bullet ibetha i-ceramic surface, iyancipha i-bullet kunye nokutyumza indawo ye-ceramic, idala iindawo ezincinci eziqhekezayo. Ngethuba lesigaba sokhukuliseko, i-bullet blunt iyaqhubeka nokutshabalalisa indawo ye-debris, yenza uluhlu oluqhubekayo lwe-debris ye-ceramic. Ekugqibeleni, ngexesha le-deformation, crack and fracture phases, i-ceramic iphantsi koxinzelelo olunzima, olukhokelela ekuqhekekeni kwayo ekugqibeleni. Amandla aseleyo emva koko achithwa ngokuguqulwa kwezinto ze-backplate.

Ezi zakhiwo zigqwesileyo kunye nenqanaba lesithathu lenkqubo yokufunxa amandla zenza ukuba i-silicon carbide imveliso yeceramic ballistic ithintele ngokufanelekileyo impembelelo yeembumbulu kwaye izenze zingabi nabungozi. Ukulinganisa i-bulletproof kufikelela kwinqanaba le-4 laseMelika, elibonelela ngokhuseleko oluphezulu kwaye lukhetho lokuqala lweengcali zomkhosi kwihlabathi.

Ukushwankathela, iiseramics ze-silicon carbide ze-sintered kunye ne-silicon carbide ceramic bulletproof series series zineenzuzo ezizodwa ngokweempawu zoomatshini, ukuzinza kwe-thermal, kunye nokusebenza kakuhle kobulletproof. Ngeempawu zabo eziphezulu, ezi zeramics zisetyenziswa ngokubanzi njengezinto zokugqoka ii-bulletproof vests kunye nezixhobo zokukhusela iitanki kunye neenqwelo zezixhobo. Ubuninzi babo obuphantsi kunye nobunzima obulula bubenza balungele ukhuseleko lomntu siqu. Njengoko itekhnoloji iqhubeka nokuhambela phambili, sinokulindela uphuhliso olongezelelekileyo kunye nokusetyenziswa kwezi ceramics ziphawuleka kukhuseleko lomntu kunye nomkhosi.
