Pulpability of bentonite
The pulping rate is the dispersion of bentonite particles in water to form a suspension, and when the apparent viscosity of this suspension is 15*10-3Ps·s, the number of cubic meters of pulp per ton of bentonite is an important indicator to measure the quality of bentonite. The pulping performance of sodium bentonite is better than that of calcium bentonite. The formula for calculating the pulp selection rate is:
Paddle making rate (m3/t) = volume of water (mL) / mass of soil (g) + 1 / density of soil. Generally, when testing the apparent viscosity, the apparent viscosity is prepared in the range of 10~25(*10-3 Pa· s) Three cups of mud within the range are stirred and left at rest for 16 hours, and then stirred again to test the viscosity, then mark the positions of three points on the single logarithmic coordinate paper, connect the lines, and find the apparent viscosity on the coordinates as 15* The amount of soil added at 10-3 Pa·s.
