In the double-liquid pulping process, medium liquid is divided into liquid A and liquid B. The liquid A is cement slurry mixed liquid and contains various components, namely cement, bentonite, additives (foaming agents and stabilizing agents) and clear water which need to be added according to the mass proportion. The liquid B is single-component water glass slurry, and only a flow meter and a delivery pump are needed for quantitative output.
The pulping process of the liquid A, the current domestic scheme is as follows: adding multiple media into the A liquid high-speed pulping machine in sequence, such as adding clear water, then adding bentonite, then adding cement, and finally adding a certain amount of foaming agent and stabilizing agent, mixing and pulping, and then outputting by a special pump.
Due to the high viscosity of the bentonite slurry and the long pulping time, the whole pulping process time is prolonged, and the pulping capacity is insufficient.
