What is the rate of making bentonite?
One of the main purposes of bentonite is used as drilling fluid materials. Mudmaking rate is one of the main indicators to measure the slurry properties of bentonite, the unit weight of the bentonite can be formulated with the apparent viscosity of suspension liquid product 15mPa - S (m3/t).
Methods: the configuration of 3 350ml bentonite suspension, soil samples of each suspension containing different mass. The apparent viscosity in (10--25) between x10-3Pa - s. Three samples were of high speed stirring for 20 minutes, 24 hours of rest. Stir for 5 minutes. Six speed rotary viscometer of apparent viscosity test. The apparent viscosity and the suspension concentration in half coordinate paper (g /100ml bentonite suspension) semi system map. Draw the line 3 points by the apparent viscosity. Determine the suspension concentration 15mPa - s apparent viscosity. Through the mud making rate table for the equivalent mudmaking rate.
Instrument: high speed agitator, six speed rotating viscosimeter
