2. Txhim kho lub zog zais, txhuam thiab flatness ntawm txheej;
3. Txhim kho qhov degree ntawm refractory thiab dej tsis kam ntawm cov txheej txheem thiab adhesion thiab adhesion ntawm cov txheej txheej txheej;
4. Bentonite tuaj yeem hloov cov hmoov calcium hnyav thiab txo tus nqi ntawm txheej txheej;
5. Txhim kho qhov kub tsis kam ntawm cov txheej txheej.

Txheej bentonite siv

Bentonite tuaj yeem ua raws li cov khoom tawg thiab cov thickener hauv cov txheej.Tsis tas li ntawd, nws tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm cov txheej txheej, kev muaj peev xwm tsis muaj dej, siab thiab tsis kub tsis kam, smoothness, thiab lwm yam. Tam sim no, kev siv bentonite hauv cov xim ntau lawm yog maj mam sib sib zog nqus.Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, txheej bentonite yuav siv dav dua.

Yuav xaiv cov xim bentonite li cas

Kev xaiv ntawm txheej bentonite yog yuav tsum tau them sai sai rau ob peb yam tsis yog whiteness, fineness, expansion times.Bentonite rau cov txheej txheem uas ua tau raws li cov kev txwv no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm txheej txheej thaum siv.Nws raug nquahu kom koj siv cov av ace xim bentonite, uas muaj qhov zoo heev thiab tus nqi tsim nyog
