Kaolin wani nau'in ma'adinai ne wanda ba na ƙarfe ba, wanda ya ƙunshi kaolinite, mica. Ya ƙunshi ragowar feldspar da quartz, yumbu ne da dutsen yumbu wanda ma'adinan yumbu na kaolinite ya mamaye. Babban abun da ke ciki na kaolin shine ma'adinan silicate da ke dauke da aluminum. A barbashi ne m da fari. Wane tasiri zai iya masana'antusodium hexametaphosphateza a kara lokacin da slurry aka desanted?
Yanayin ajiya ragowar kaolin shine babban nau'in ajiyar kaolin, wanda ke da yawan yashi. Gabaɗaya, wajibi ne a cire yashi kuma kawai riƙe ƙasa a cikinta lokacin amfani da shi. Yin amfani da sodium h6-metaphosphate masana'antu a matsayin mai rarrabawa zai iya taka muhimmiyar rawa wajen rarraba ƙasa da yashi da kuma guje wa ɓarna na albarkatu.
A halin yanzu, tsarin cire yashi gabaɗaya yana ɗaukar hanyar slurry desanding, yana ƙara rarrabuwa zuwa slurry, ta yadda ƙasa da yashi a cikin taman kaolin za a iya raba su cikin sauri da inganci. Ana cire yashi ta hanyar nauyi, kuma ana samun slurry kaolin. Mai rarraba da aka fi amfani da shi shine masana'antusodium hexametaphosphate, saboda masana'antusodium hexametaphosphatetasirin rabuwa yana da kyau.
Matakan aiki na musamman na amfani da masana'antusodium hexametaphosphatedon cire yashi daga kaolin slurry sune kamar haka:
1. Shiri na slurry: kaolin raw tama gauraye da ruwa, ƙara alkali bayani don daidaita pH darajar, kaolin slurry;
2 shirye-shiryen watsawa: masana'antusodium hexametaphosphateda sodium silicate da aka kara a cikin ruwa, gauraye don samun fili mai rarraba;
3. Slurry: amfani da masana'antusodium hexametaphosphatefili dispersant ƙara zuwa kaolin slurry, bayan hadawa slurry;
4. Cire yashi: an cire yashi ma'adini a cikin ɓangaren litattafan almara da aka tarwatsa a ƙarƙashin aikin nauyi, da kuma ƙwayar kaolin bayan an cire yashi.
Masana'antusodium hexametaphosphatesamar da Shandong Jufu Chemical Technology Co., Ltd. ana samar da su ta hanyar thermal tsari, tare da ƙarancin ƙazanta, ingantaccen inganci da ƙarancin sashi.
