M'malingaliro a anthu, ceramic ndi yosalimba.Komabe, pambuyo pokonza teknoloji yamakono, zoumba "zosinthidwa", kukhala zolimba, zamphamvu kwambiri zatsopano, makamaka m'munda wa zipangizo zopangira zipolopolo zomwe zimakhala ndi thupi lapadera, zoumba zimawala, zimakhala zodziwika kwambiri za bulletproof.
① Mfundo yopanda zipolopolo ya zida za ceramic
Mfundo yofunika kwambiri yotetezera zida ndikugwiritsa ntchito mphamvu ya projectile, kuichepetsa, ndikuipangitsa kukhala yopanda vuto.Zida zambiri zamainjiniya, monga zitsulo, zimayamwa mphamvu kudzera pamapindika a pulasitiki, pomwe zida za ceramic zimatenga mphamvu kudzera pakuphwanya kwapang'onopang'ono.
Njira yamayamwidwe amagetsi a ceramics of bulletproof imatha kugawidwa m'magawo atatu:
(1) Gawo loyambira: Chojambulacho chimakhudza pamwamba pa ceramic, kupangitsa kuti zida zankhondo zikhale zosamveka komanso zopatsa mphamvu panthawi yakuphwanya ndikupanga tizidutswa tating'ono ndi zolimba pamtunda;
(2) Gawo la kukokoloka: Cholozera chophwanyika chikupitilira kuwononga malo ong'ambika, ndikupanga kusanjikiza kosalekeza kwa zidutswa za ceramic;
(3) Mapindikidwe, kusweka, ndi kusweka: Pomaliza, kupsinjika kwamphamvu kumapangidwa mu ceramic, ndikupangitsa kuti iphwanyike.Kenako, mbale kumbuyo deforms, ndi mphamvu zonse otsala odzipereka ndi mapindikidwe a mbale kumbuyo zakuthupi.Panthawi ya projekiti pazitsulo za ceramic, projectile ndi ceramics zimawonongeka.
②Zofunikira pazakuthupi zama ceramics oteteza zipolopolo
Chifukwa cha kuwonongeka kwa ceramic yokha, imasweka ikakhudzidwa ndi projectile osati kupunduka kwa pulasitiki.Pansi pa ntchito yolemetsa, kupasuka koyamba kumachitika m'malo osiyanasiyana monga pores ndi malire a tirigu.Chifukwa chake, kuti muchepetse kupsinjika kwapang'onopang'ono, zida zadothi zankhondo ziyenera kukhala zapamwamba kwambiri zokhala ndi porosity yochepa (mpaka 99% ya mtengo woyerekeza) komanso kapangidwe kabwino kambewu.
Katundu | Kukhudza magwiridwe antchito a bulletproof |
Kuchulukana | Ubwino wa zida zankhondo |
Kuuma | Mlingo wa kuwonongeka kwa projectile |
Modulus ya elasticity | Kufalikira kwa mafunde a Stress |
Kulimba | Kukana nkhonya zambiri |
Kulimba kwa fracture | Kukana nkhonya zambiri |
Chitsanzo cha Fracture | Kutha kuyamwa mphamvu |
Microstructure (kukula kwa tirigu, gawo lachiwiri, kusintha kwa gawo kapena amorphous (kupsinjika), porosity) | Zimakhudza machitidwe onse omwe akufotokozedwa kumanzere |
Katundu wa zinthu ndi zotsatira zake pa katundu zipolopolo
Silicon carbide ceramic kachulukidwe ndizochepa, zolimba kwambiri, ndizopangira zopangira zotsika mtengo, kotero ndizomwe zimagwiritsidwa ntchito kwambiri ndi zipolopolo zadothi ku China.
Boron carbide ceramics ali ndi kachulukidwe otsika kwambiri komanso kuuma kwambiri pakati pa zoumbazi, koma nthawi yomweyo, zomwe zimafunikira pakukonza ukadaulo ndizokwera kwambiri, zomwe zimafunikira kutentha kwambiri komanso kutsika kwapang'onopang'ono, kotero mtengo wake ndi wapamwamba kwambiri pakati pazida zitatuzi.
