Preparation method of wafer-shaped solid waste-based porous geopolymer pH regulator
The invention relates to a preparation method of a wafer-shaped solid waste-based porous geopolymer pH regulator. The invention belongs to the field of pH regulators. The invention aims to solve the technical problems of low pH buffer capacity and short duration of existing geopolymers used as pH regulators. The method comprises the following steps: 1, preparing an alkali-activated solution; 2, adding solid waste powder into the alkali-activated solution, adding a foaming agent, and continuing stirring until solid waste powder and a foaming agent are uniformly mixed to obtain polymer slurry; 3, dropwise adding the polymer slurry into a preheated oil continuous phase at a constant speed, and conducting curing in a drying oven to obtain a regulator; and 4, removing the residual oil continuous phase on the surface, and conducting drying to obtain the wafer-shaped solid waste-based porous geopolymer pH regulator. According to the method, raw materials are easy to obtain, operation is simple, and the obtained regulator has a high-connectivity pore structure, high pH regulation capability and longer pH regulation time.
