How can I solve the problem that the swelling of the bentonite is slow and the viscosity is low?
Bentonite can be modified by sodium as a replacement reaction. It requires the replacement of calcium in the water solution and calcium in the bentonite. Extrusion shear is to allow the reaction to be sufficient, and the temperature is to shorten the reaction time. Field heap sodium long time, but also frequently flip. The reaction is incomplete. A large number of free bases exist, resulting in slow pulping
Less or no polymer. They are physically viscous and slow to hydrolyze.
Sodium process. The correct process can save costs and improve quality. Dry and soda is not good.
Bentonite raw ore. CEC-Na's high and low
