Alumina VS Silicon Ceramic Armor Plate

Ceramic bulletproof sheet (mbale ya bulletproof)ndi gawo lofunikira la zida zoteteza zipolopolo.Pakadali pano, zoumba za silicon carbide ceramic ndi aluminiyamu apamwamba kwambiri ndizinthu ziwiri zomwe zimafunidwa kwambiri pamsika.Chifukwa njira yoteteza zipolopolo imachitika pakanthawi kochepa, zoumba zoteteza zipolopolo zimafunikira zinthu zambiri, monga kusalimba, porosity, kuuma, kulimba kwa fracture, zotanuka modulus, kuthamanga kwa mawu ndi mphamvu zamakina, ndi zina zambiri.

Chemshun ceramic alumina ballistic sheet imapangidwa ndi aluminiyamu yabwino kwambiri ngati chinthu chachikulu.Kuyera kwa α-Al₂O₃ kumaposa 99%, kachulukidwe ndi ≥3.9g/cm³, porosity ili pafupi ndi zero, ndipo kuchuluka kwa kuyamwa kwamadzi sikudutsa 0.02%.Kuuma kutha kufika pamwamba pa HRA88, chomwe ndi chinthu choyamba chosankha pazadothi zoteteza zipolopolo.Mulingo wa zipolopolo umaposa muyezo waku America wa 3. Pa nthawi yomweyo, umakwaniritsanso zosowa za makasitomala a silicon carbide bulletproof ceramics.Kachulukidwe ndi ≥3.1g/cm³, kuuma kwake ndi ≥HRA92, ndipo giredi yachipolopolo imatha kufika ku American Standard 4.

Kukula kwa chemshun alumina bulletproof ceramic pepala ndi 50 * 50 * 10mm ndi 50 * 25 * 10mm, ndi kukula wokhazikika wa pakachitsulo carbide ceramic ndi 250 * 300mm.Makasitomala ali ndi zina zambiri ndipo amatha kuvomereza makonda.
