Kaolin waa nooc ka mid ah macdanta aan biraha ahayn, oo inta badan ka kooban kaolinite, mica. Ka kooban feldspar haraaga ah iyo quartz, waa dhoobo iyo dhagax dhoobo ah oo ay ku badan yihiin macdanta dhoobada kaolinite. Halabuurka ugu muhiimsan ee kaolin waa inta badan macdanta silicate ee ka kooban aluminium. Qaybaha ayaa ah kuwo jilicsan oo cad. Waa maxay saamaynta warshadayntasodium hexametaphosphatelagu daraa marka slurry-ka la desan yahay?
Debaajiga kaolin-ka hadhaaga cimilada ayaa ah nooca ugu muhiimsan ee deebaajiga kaolin, kaas oo leh maaddo ciid sare leh. Guud ahaan, waa lagama maarmaan in ciidda laga saaro oo kaliya lagu hayo ciidda dhexdeeda marka la isticmaalayo. Isticmaalka sodium h6-metaphosphate ee warshadaynta sida faafinta waxay door wanaagsan ka ciyaari kartaa kala-soocidda ciidda iyo ciidda waxayna ka fogaan kartaa qashinka kheyraadka.
Waqtigan xaadirka ah, habka ka saarista ciidda guud ahaan wuxuu qaataa habka slurry desaning, isagoo ku daraya kala firdhiyaa slurry, si ciidda iyo ciidda ku jira macdanta kaolin loo kala saaro si dhakhso ah oo hufan. Ciidda waxaa meesha ka saaraya cufisjiid, kaolin slurry ayaa la helaa. Qaybaha inta badan la isticmaalo waa warshadosodium hexametaphosphate, sababtoo ah warshadahasodium hexametaphosphateSaamaynta kala soociddu waa wanaagsan tahay.
Tallaabooyinka hawlgalka gaarka ah ee isticmaalka warshadahasodium hexametaphosphatesi ciidda looga saaro slurry kaolin waa sida soo socota:
1. Diyaarinta slurry: kaolin macdanta ceeriin oo lagu qaso biyo, ku darida xalalka alkali si loo hagaajiyo qiimaha pH, kaolin slurry;
2 diyaarinta kala firdhiso: warshadahasodium hexametaphosphateiyo sodium silicate oo lagu daray biyaha, isku qasan si loo helo kala firdhiso isku dhafan;
3. Slurry: isticmaalka warshadahasodium hexametaphosphatekala firdhiso isku dhafan oo lagu daray slurry kaolin, ka dib marka la isku daro slurry;
4. Bacaad ka saarista: ciidda quartz ee saxarka kala firdhiyey ayaa la saaraa iyada oo la raacayo ficilka cufisjiidka, iyo saxarka kaolin ka dib marka ciidda la saaro.
Warshadahasodium hexametaphosphateay soo saartay Shandong Jufu Chemical Technology Co., Ltd. waxaa soo saaray habka kulaylka, oo leh wasakh yar, tayo deggan iyo qiyaas yar.
