Pob zeb Gaoling yog ib qho tseem ceeb heev uas tsis yog hlau. Cov kaolin uas tsim los ntawm kev sib tsoo, sib tsoo thiab calcination muaj ntau yam khoom zoo heev, thiab tau siv dav hauv ntau yam lag luam, tshwj xeeb tshaj yog hauv kev lag luam txheej. Tam sim no, tus nqi ntawm cov khoom siv calcined kaolin ib txwm yog qis, tab sis nws lub zog npog tsis zoo tagnrho, uas txwv nws daim ntawv thov hauv kev lag luam ntawm cov txheej txheem siab. Qhov no tau qhia tias nrog kev nce ntawm qhov loj me ntawm cov khoom me me, lub zog npog ntawm calcined kaolin maj mam nce, qhov laj thawj tseem ceeb yog tias cov khoom me me kaolin, lub zog npog ntau dua.Kev sib tsoo kaolinyog ib qho khoom siv ntau lawm siv rau kev ua 300-1250 ultra fine kaolin los txhim kho nws lub zog npog. Nws cov txiaj ntsig yog dab tsi? Niaj hnub no los ntawm lub chaw tsim khoom kaolin zebGuilin Hongcheng rau koj ib qho kev qhia ntxaws ntxaws.

Tom qab tsoo, sib tsoo thiab ua kom zoo dua qub, 850 ℃ calcination, uas muab cov ntaub ntawv siv tau rau kev siv thiab kev ua cov kaolin hauv lub tshuab thee. Vim nws muaj cov silicon thiab txhuas ntau, kaolin tsis yooj yim puas thiab nyuaj rau hnav. Nws yuav tsum tau ua kom zoo (325 mesh sieve 5% ~ 10%), thiab lub tshuab Raymond ib txwm tsis tuaj yeem ua tiav cov txiaj ntsig siab ntawm qhov zoo no.
