Preparation method of composite high-viscosity slurry bentonite
The invention relates to a preparation method of composite high-viscosity slurry bentonite, and effectively solves the problems that the existing preparation method for improving the viscosity of bentonite has tedious steps, the addition proportion of various raw materials cannot be well controlled, the viscosity of slurry cannot reach the highest, and composite high-viscosity slurry is inconvenient to prepare. According to the technical scheme, according to the preparation method of the composite high-viscosity slurry bentonite, alkaline modified raw materials and CMC are fully mixed with original bentonite slurry according to a specific proportion, the alkaline modified raw materials can adjust the PH value of the slurry, bentonite is promoted to be dispersed for slurry making, meanwhile, water loss of the slurry can be reduced, the viscosity and shearing force of the slurry are improved, and the composite high-viscosity slurry bentonite is prepared. The CMC can improve the viscosity of the slurry and further improve the viscosity of the bentonite slurry, and the equipment for implementing the preparation method can be convenient for operators to accurately control the adding proportion of each additive according to the amount of bentonite, and the additives are fully and uniformly mixed through the mixing mechanism, so that the completely mixed slurry has higher viscosity.
本发明涉及一种复合型高粘泥浆膨润土制备方法，本发明有效解决了现有提高膨润土粘性的制备方法步骤繁琐，不能很好的控制各种原料的添加比例，使泥浆的粘性不能达到最高，不便于制备复合型高粘泥浆的问题；解决的技术方案包括：一种复合型高粘泥浆膨润土制备方法通过特定比例的碱性改性原料和CMC与膨润土原土泥浆充分混合，碱性改性原料能调节泥浆PH值，促使膨润土分散造浆，同时能降低泥浆的失水，提高泥浆的粘度和切力，CMC能提高泥浆的粘稠度，进一步提高膨润土泥浆的粘度，而用于实施该制备方法的设备能便于操作人员根据膨润土的量而准确控制各个添加剂的添加比例，并通过混合机构将其充分混合均匀，使完全混合后的泥浆具有较高的粘性。
