Alumina Ceramic Ntau Lawm Txheej Txheem

Hmoov npaj

Lub alumina hmoov nkag mus rau hauv lub Hoobkas yog npaj rau hauv cov hmoov ntawv raws li cov khoom sib txawv thiab cov txheej txheem molding sib txawv. Lub particle loj ntawm hmoov yog hauv qab 1μm. Yog tias cov khoom lag luam siab-alumina ceramic tsim cov khoom lag luam, ntxiv rau alumina purity ntawm 99.99%, ultra-nplua pulverization thiab uniform particle loj faib yuav tsum. Thaum extrusion molding los yog txhaj tshuaj molding yog siv, phau ntawv sau thiab yas yuav tsum tau qhia rau hauv cov hmoov, feem ntau thermoplastic yas lossis yas nrog qhov hnyav ntawm 10-30%. Cov kab mob organic yuav tsum yog nyob ntawm qhov kub li ntawm 150-200 nrog alumina hmoov. Sib tov sib xyaw rau hauv qab txos kom yooj yim rau kev lag luam molding. Cov hmoov nyoos tsim los ntawm qhov kub nias txheej txheem tsis tas yuav ntxiv ib lub binder. Yog tias semi-automatic lossis tag nrho tsis siv neeg qhuav nias siv, muaj qhov tshwj xeeb cov txheej txheem rau cov hmoov, thiab cov hmoov yuav tsum tau ua tiav los ntawm cov tshuaj tsuag granulation ua kom nws kheej kheej, thiaj li txhawm rau txhim kho cov npliag ntawm cov hmoov thiab ua kom zoo li tsis siv neeg puv. ntawm lub pwm thaum lub sij hawm txhaj tshuaj molding. ntsa. Tsis tas li ntawd, txhawm rau txo qis kev sib txhuam ntawm cov hmoov thiab pwm phab ntsa, nws yog qhov yuav tsum tau ntxiv 1 mus rau 2% ntawm cov roj nplua nyeem, xws li stearic acid, thiab binder PVA.

Thaum cov nias qhuav yog qhov xav tau, cov hmoov yuav tsum tau txau thiab granulated, thiab cawv cawv polyvinyl yog ua cov ntawv qhia. Lub koom haum tshawb nrhiav hauv Shanghai tau tsim cov dej-soluble paraffin los siv ua cov ntawv ci rau Al203 txau granulation, uas muaj cov npliag zoo hauv qab cua sov. Cov hmoov tom qab txau granulation yuav tsum muaj qhov zoo fluidity, xoob ntom ntom, thiab ntws lub kaum kev sib txhuam tsis kub tshaj 30 ℃. Kev xav txog cov particle gradation piv thiab lwm yam xwm txheej kom tau txais qhov loj ntawm qhov ntsuab ntsuab.
