Mukugadzira simbi, kugadzira simbi nedzimwe nzvimbo dzekugadzira maindasitiri,machira esimbi ealuminaZvinowanzo shandiswa pakugadzira zvinhu zvinodzivirira kupfekwa kwemidziyo. Zvinonyanya kugadzirwa nehupfu hwealumina sezvinhu zvisina kugadzirwa kuburikidza nemaitiro akasiyana-siyana, akadai sekuumba, calcination uye post-processing. Zvinhu izvi zvine kugadzikana kwekupisa kwakanyanya, zvinodzivirira kupfekwa zvakanyanya uye zvinodzivirira kupisa, saka zvinoshandiswa zvakanyanya mumichina, lithium battery, indasitiri yemakemikari nedzimwe nzvimbo. Pamusoro pezvo, huwandu hwezvinhu zvealumina ceramic chinhu chakakosha chinokanganisa mashandiro azvo. Saka, zvinhu zvipi zvinokanganisa huwandu hwealumina ceramics?
1: Mhedzisiro yekuchena kwealumina
Ngatitangei tataura nezve simba rezvinhu zvakagadzirwa pa alumina ceramics. Chinhu chikuru che alumina ceramics tile liner i alumina, uye kuchena nehukuru hwe particles zve alumina zvinokanganisa zvakananga density ye alumina ceramics. Kuchena kwakanyanya, density yakakura, uye particles size zvinokanganisa kuunganidzwa kwe alumina panguva yekuumbwa. Kuderera kwe particles size, kuunganidzwa kwakasimba, uye density yakakwira mushure me calcination. Pamusoro pezvo, zvimwe zvinhu zvinogona kuwedzerwa zvakakodzera panguva yekugadzira kugadzirisa density ye alumina ceramics kuti ienderane nezvinodiwa zvezvigadzirwa zvakasiyana.
2: Kupesvedzera kweNzira yekuumba
Mhedzisiro yekuumbwa kwealumina ceramics tile liner inofanira kufungwa nezvayo. Nzira dzekuumba dzealumina ceramics dzinosanganisira dry pressing molding, injection molding process uye extrusion molding. Nzira idzi dzinokanganisa zvakananga huwandu hwechigadzirwa chapera.
3: hunyanzvi hwevashandi
Kugadzira sintering ndeimwe yenzira huru mukugadzirwa kwealumina ceramics, iyo inogona kukurudzira kugadzirwa kwekristaro kwezvinhu zvakagadziriswa uye kugadzira zvigadzirwa zveceramic. Zvinodiwa mukugadzira sintering, zvakaita sekupisa, nguva, mhepo uye mwero wekutonhora, zvinokanganisa huwandu hwechigadzirwa chapera. Kugadzira sintering zvakanyanya kunogona kuwedzera huwandu hwechigadzirwa chapera, asi kupisa kwakanyanya kunogona kukonzera kutsemuka kana kushanduka kwealumina ceramics. Saka, kuti uwane huwandu uye hunhu hwaunoda, zvakakosha kusarudza maparamendi akakodzera ekugadzira sintering.
