Embodiment 1
[0049] Formulation (with mass parts):
[0050]
[0051] According to the above formulation ratio, liquid water glass, 50% liquid base (aqueous solution of aqueous sodium hydroxide), sodium hydroxide, sodium hydroxide, and water were mixed with water at 150 r / min, and then slowly The -OH carboxylic acid polymer was added, and the mixture was allowed for 10 min to uniform at a speed of 150 r / min while adding, and then slowly added sodium pentewater-biased silicate, and the mixture was mechanically stirred at a speed of 150 r / min while adding 10 min to uniform. To produce desulfurization wastewater extracts.
[0052] Take 200g Yingcai Soil BC01, add 0.6% of the desulfurization wastewater gel, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water moratorium, and produce a uniform mud in the planetary ball mill. Then, the mud viscosity was measured, and the initial viscosity of the mud was 37.6 s; after standing for 5 min, the viscosity was measured, the slur...
Embodiment 2
[0054] Formulation (with mass parts):
[0055]
[0056] According to the above formulation ratio, the liquid water glass, 50% liquid base, sodium tripolyphosphate and water were first mixed, and the mixture was stirred at 150 r / min to uniform; then the S-carboxylic acid polymer was slowly added, and when added The mixture is mechanically stirred at 150 r / min to uniform; finally sodium hexaphosphate is slowly added, and the mixture is mechanically stirred at 150 r / min at a speed of 10 min to uniform, and the desulfurization wastewater extract is obtained.
[0057] Take 200g Yingcai Soil BC01, add 0.5% of the desulfurization wastewater extractant, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water grinding, and a uniform mud. Then the mud was coated with a -4 cup to measure the slurry viscosity, the initial viscosity of the mud was 47.5 s; after standing for 5 min, the viscosity was measured, the slurry viscosity was 87.4, and the thixotropy index was 1...
Embodiment 3
[0059] Formulation (with mass parts):
[0060]
[0061] According to the above formulation ratio, liquid water glass, 30% liquid base, pyrophosphate and water are mixed, and the mix is mechanically stirred; then the S carboxylic acid polymer is slowly added, and the side is added while adding; The mixture is mechanically stirred at 150 r / min to uniform, and the desulfurization wastewater extract is obtained while adding.
[0062] Take 200g Yingcai Soil BC01, add 0.5% of the desulfurization wastewater extractant, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water grinding, and a uniform mud. Then the mud was applied to the -4 cup to measure the viscosity of the mud, and the initial viscosity of the mud was 48.8 s; after standing for 5 min, the viscosity was measured, the slurry viscosity was 87.5s, and the thixotropy index was 1.793.
