Alumina ceramics lahkawng n bung ai ladat lahkawng
Alumina ceramic arung arai ni a hkrang shapraw ai ladat ni gaw, hka lim ai, n-gun ja ai, n-gun n rawng ai, katsi ai isostatic n-gun, tsi htu ai, casting, n-gun ja ai hte n-gun ja ai isostostatic pressing ni lawm ai. Kade nna ai aten hta, buga hte maigan mungdan ni hta, filter n-gun, direct solidification injection, gel bang ai n-gun, centrifugal tsi htu ai hte n-gun ja ai n-gun n rawng ai n-gun rawng ai hpaji masa ni hpe gyin shalat wa sai. Hpa majaw nga yang, n bung ai arung arai ni a hkrang, n bung ai hkrang, n bung ai hkrang hte hkrak ai arung arai ni gaw, n bung ai molding ladat ni ra ai.

Masha law malawng lang ai alumina ceramic ni hpe lang ai ladat lahkawng hpe shalawm da ai:
. Molding ladat ni gaw uniaxial (sh) bidirectional re. Dai press hta hydraulic amyu lahkawng nga ai hte jak amyu lahkawng nga ai, dai gaw semi-automatic (sh) shi hkum shi galaw ai ladat rai mai ai. 200Mpa ngu ai n-gun grau law ai. Dai pru ai lam gaw minit mi hta 15 ~ 50 daram du lu ai. Hydraulic n-gun n bung ai majaw, powder filling n bung ai shaloi, n-gun rawng ai daw ni a tsaw ai gaw n bung ai. Mechanical press hku nna lang ai n-gun a kaba ai lam gaw, powder hpe jahpring ai n-gun a majaw n bung ai, dai gaw sintering ngut ai hpang shrinkage n bung ai lam hpe byin shangun nna, dai product a quality hpe hkra machyi shangun ai. Dai majaw, dry pressing galaw ai hta powder particles ni a langai sha re ai garan ginhka ai lam gaw, n-gup n-gu hpe jahpring na matu grai ahkyak nga ai. Dai hpring ai gumhpraw gaw hkrak ai kun n hkrak ai kun ngu ai gaw, galaw shapraw da ai alumina ceramic daw ni hpe dimensional hkrak ai hku hkang lu ai atsam hpe grai shadut ya ai. 60μm jan nga ai Powder particles ni, 60 ~ 200 mesh lapran hta kaja dik htum pressure molding effect hpe lu la na matu, n-gun grau law ai free flow effect hpe lu la mai ai.
2, grouting molding ladat: gutina ceramic ni a matu lang ai shawng nnan na molding ladat re. Gypsum mold hpe lang ai majaw, manu n law ai hte, kaba ai hte n bung ai hkrang daw ni hpe galaw na matu loi ai. Griuting molding a madung gaw alumina slurry hpe hkyen lajang ai lam rai nga ai. Kalang lang hka hpe flux medium hku lang nna, dai hpang deguming agent hte binder hpe jat bang nna, hkum tsup ai hku htu ngut ai hpang, gas hpe shapraw kau nna, plaster mold hpe hpang de ru kau ya ai. Hka hpe hkap la ai majaw, plaster mold a capillaries ni a majaw, slurry gaw mold hta ngang kang wa ai. Hollow grouting hta, n-gun grau law ai slurry hpe, n-gup magap ntsa e shinggrup da ai slurry gaw ra ai n-gun de du wa ai shaloi, ru kau ra ai. Hkum hkrang hpe shayawm kau na matu, n-gun ja ai slurry hpe mai byin ai daram lang ra ai.
Organic additives ni hpe mung alumina ceramic slurry hta bang nna, slurry particles ni a ntsa e wan n-gun lahkawng hpe galaw ra ai majaw, slurry hpe n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun rawng ai hku n-gun n rawng hkra tawn da ra ai. Dai hta n-ga, vinyl alcohol, methyl cellulose, alginate amine hte polyacrylamide hte gum Arabic zawn re ai garan ginhka ai ni zawn re ai binder ni hpe jat bang nna, n-gun ja ai n-gun hpe gram lajang na matu htuk manu hkra galaw ya ai.
