Kaolin yog ib yam khoom uas tsis yog xim hlau, feem ntau muaj li ntawm kaolinite, mica. Ua los ntawm cov seem feldspar thiab quartz, nws yog av nplaum thiab av nplaum pob zeb dominated los ntawm kaolinite av nplaum ntxhia. Lub ntsiab muaj pes tsawg leeg ntawm kaolin yog feem ntau silicate minerals uas muaj txhuas. Cov khoom yog mos thiab dawb. Dab tsi cuam tshuam tuaj yeem ua lag luamsodium hexametaphosphateyuav ntxiv thaum lub slurry yog desanted?
Weathering residual kaolin deposit yog hom tseem ceeb ntawm kaolin deposit, uas muaj cov xuab zeb siab. Feem ntau, nws yog ib qho tsim nyog kom tshem tawm cov xuab zeb thiab tsuas yog khaws cov av hauv nws thaum siv nws. Siv kev lag luam sodium h6-metaphosphate li dispersant tuaj yeem ua lub luag haujlwm zoo hauv kev sib cais ntawm cov av thiab cov xuab zeb thiab zam cov khoom pov tseg.
Tam sim no, cov txheej txheem ntawm cov xuab zeb tshem tawm feem ntau siv cov txheej txheem ntawm slurry desanding, ntxiv cov dispersant rau slurry, kom cov av thiab xuab zeb hauv kaolin ore tuaj yeem sib cais sai dua thiab ua tau zoo. Cov xuab zeb raug tshem tawm los ntawm lub ntiajteb txawj nqus, thiab cov kaolin slurry tau txais. Cov dispersant feem ntau siv yog industrialsodium hexametaphosphate, vim industrialsodium hexametaphosphatekev sib cais yog qhov zoo.
Cov txheej txheem ua haujlwm tshwj xeeb ntawm kev siv kev lag luamsodium hexametaphosphateYuav kom tshem tawm cov xuab zeb los ntawm kaolin slurry yog raws li nram no:
1. Kev npaj ntawm slurry: kaolin nyoos ore tov nrog dej, ntxiv alkali tov los kho pH nqi, kaolin slurry;
2 kev npaj ntawm dispersant: industrialsodium hexametaphosphatethiab sodium silicate ntxiv rau dej, sib tov kom tau ib qho tshuaj dispersant;
3. Slurry: siv kev lag luamsodium hexametaphosphatecompound dispersant ntxiv rau kaolin slurry, tom qab sib tov slurry;
4. Cov xuab zeb tshem tawm: quartz xuab zeb nyob rau hauv dispersed pulp yog muab tshem tawm nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus, thiab cov kaolin pulp tom qab tshem tawm cov xuab zeb.
Kev lag luamsodium hexametaphosphateua los ntawm Shandong Jufu Chemical Technology Co., Ltd. yog tsim los ntawm cov txheej txheem thermal, nrog tsawg impurities, ruaj khov zoo thiab tsawg npaum li cas.
