Kev npaj Technology ntawm Alumina Ceramics (1)

Kev npaj hmoov

Alumina hmoovyog npaj rau hauv cov khoom siv hmoov raws li cov khoom sib txawv thiab cov txheej txheem molding sib txawv.Qhov loj me ntawm cov hmoov yog tsawg dua 1μm.Yog tias nws tsim nyog los tsim cov khoom lag luam siab purity alumina ceramic, ntxiv rau qhov purity ntawm alumina yuav tsum tau tswj nyob rau hauv 99.99%, nws kuj yuav tsum tau nqa tawm ultrafine sib tsoo txheej txheem kom nws cov particle loj faib uniform.

Thaum siv extrusion molding los yog txhaj tshuaj molding, binder thiab yas tus neeg sawv cev yuav tsum tau nkag mus rau hauv cov hmoov, feem ntau nyob rau hauv qhov hnyav piv ntawm 10-30% thermoplastic yas los yog resin, organic binder yuav tsum tau tov nrog alumina hmoov ntawm 150-200 ℃ kub tusyees, txhawm rau ua kom yooj yim rau kev ua haujlwm molding.

Cov ntaub ntawv hmoov tsim los ntawm cov txheej txheem kub nias tsis tas yuav ntxiv cov ntawv khi.Yog tias siv semi-automatic lossis tsis siv neeg qhuav nias molding, muaj cov kev cai tshwj xeeb rau cov hmoov, peb yuav tsum siv cov tshuaj tsuag granulation txoj kev kho cov hmoov, ua kom nws zoo li spherical, txhawm rau txhim kho fluidity ntawm cov hmoov, yooj yim. mus sau cov pwm phab ntsa txiav hauv txoj kev.Txau granulation ntawm cov hmoov yuav tsum tau thaum lub sij hawm qhuav nias, thiab polyvinyl cawv yog qhia raws li binder.Nyob rau hauv xyoo tas los no, ib lub koom haum tshawb fawb hauv Shanghai tau tsim cov dej-soluble paraffin ua cov ntawv khi rau cov tshuaj tsuag granulation ntawm Al2O3, uas muaj cov dej zoo hauv qab cua sov.Cov hmoov tom qab tshuaj tsuag granulation yuav tsum muaj fluidity zoo, xoob ntom, ntws Angle kev sib txhuam kub tsawg dua 30 ℃, zoo tagnrho particle loj piv thiab lwm yam kev mob, thiaj li yuav tau txais ib tug ntau dua ntom ntawm dawb ntsuab.

Txoj kev molding

Cov txheej txheem molding ntawmalumina ceramic khoomsuav nrog qhuav nias, grouting, extrusion, txias isostatic nias, txhaj tshuaj, ntws casting, kub nias thiab kub isostatic nias.Nyob rau hauv xyoo tsis ntev los no nyob rau hauv tsev thiab txawv teb chaws kuj tsim siab lim molding, ncaj qha solidification txhaj molding, gel txhaj molding, centrifugal txhaj molding thiab khoom dawb molding tshuab txoj kev.Cov duab sib txawv, qhov ntau thiab tsawg, cov duab nyuaj thiab cov khoom lag luam xav tau cov txheej txheem molding sib txawv.
