| Abstract: | Using low-grade bentonite as the main material and based on the theory analysis of static electricity effect,stereo-hindrance effect and complex effects,a new advanced organic compound deflocculant was prepared.The influence of deflocculant,solid content and milling time on slurry properties were analyzed by XRD,Zeta potential analysis methods and so on.The results show that the main components of the new advanced deflocculant are sodium tripolyphosphate,sodium pyrophosphate,and sodium oxalate.When the mass ratio is 1∶2∶2,the dosage is 0.50%,and the water content achieves 60%,the deflocculant having the best properties can be obtained,the fluidity of ceramic slurry is less than 28 s and the slurry has good stablitity. |
