Embodiment Construction
[0026] Below in conjunction with embodiment the present invention will be further described:
[0027] 1. The bentonite ingredients after acidification are composed of the following components by weight percentage: 94.5% of bentonite semi-finished products after acidification, 2.3% of instant sodium silicate, 2% of polyvinyl alcohol, 1% of hydroxypropyl methylcellulose and 0.2% of sodium carbonate %.
[0028] 2. The production method of acidified bentonite: input the acidified bentonite ingredients into a mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the finished product of acidified bentonite.
[0029] 3. The production method of semi-finished bentonite after acidification: (1) first input the naturally weathered bentonite into the running mixer, then slowly add dilute sulfuric acid into the naturally weathered bentonite for acidification; (2) put the acidified bentonite, It is extruded into bentonite flakes by a pair of rollers, and ...
