Research on Preparation Technology Parameters of Two Organically Modified Bentonites

Article Preview

Abstract:

This paper adopts the laboratory simulation methods and makes explorations on the best modification parameters of Bentonite affected by two kinds of organic substances, pig manure degradable solution and HDTMA. The best preparation technology condition for pig manure degradable solution modification Bentonite is W pig manure: WBentonite=3:1 (mass ratio). PH is 9. The reaction temperature is 40°C and the reaction time is 4h. The best preparation technology condition for HDTMA modification Bentonite is WHDTMA: WBentonite =1:2 (mass ratio). PH is 7. The reaction temperature is 90°C and the reaction time is 2.5h.
