Alumina tej hub hluav taws tshuab

Cov txheej txheem thev naus laus zis ntawm densifying granular ceramic lub cev thiab tsim cov khoom tawv yog hu ua sintering. Sintering yog ib txoj hauv kev los tshem tawm cov voids ntawm cov lus hauv lub cev ntsuab, tshem tawm ib qho me me ntawm cov roj thiab lub cev tsis huv cov organic, kom cov hais me me tuaj yeem loj hlob thiab sib txuas ua ke los tsim cov tshuaj tshiab.

Cov khoom siv cua sov siv rau kev tua hluav taws yog qhov cub siv hluav taws xob feem ntau. Ntxiv nrog rau qhov atmospheric sintering, uas yog lub siab tsis sib thooj, tseem muaj kub nias sintering thiab kub isostatic nias sintering. Txawm hais tias tas mus li kub-nias sintering nce ntxiv cov zis, cov khoom siv thiab cov nqi pwm siab dhau. Ntxiv rau, vim tias cov cua kub axial, lub sijhawm ntev ntawm cov khoom lag luam yog tsawg. Kub isostatic nias siv qhov kub thiab txias thiab kub siab roj raws li lub siab xa hluav taws xob nruab nrab, uas muaj qhov zoo ntawm cov cua kub tsis sib xws hauv txhua qhov kev qhia, thiab nws haum rau cov khoom lag luam sintering nrog cov qauv duab. Vim tias cov qauv kev teeb tsa, cov khoom siv ua haujlwm yog 30-50% siab tshaj qhov ntawm txias-nias sintering. 10-15% siab dua dav dua kub nias sintering. Yog li no, qee qhov muaj txiaj ntsig ntxiv alumina ceramic khoom lag luam lossis cov khoom tshwj xeeb uas yuav tsum tau los ntawm kev tiv thaiv kev tiv thaiv kev lag luam hauv teb chaws, xws li cov nplaim hluav taws xob, cov khoom siv hluav taws xob, cov roj nuclear thiab cov phom phom, raug tua los ntawm kub isostatic siab.

Ib qho ntxiv, microwave sintering, arc plasma sintering, thiab kev tiv thaiv tus kheej sintering technology kuj tseem nyob hauv kev txhim kho thiab tshawb nrhiav.
