Preparation method of hydrosol solution

A preparation method of hydrosol solution, comprising the following steps:

• classifying total materials required for the preparation of the hydrosol solution according to material properties, and allocating the classified materials to each of feeding stations (300) of a hydrosol solution preparation system for later use according to the material properties;
• turning on a heating system of the hydrosol solution preparation system to preheat a processing pipeline (101) of a mixing and shearing device (100) to make the temperature inside the processing pipeline (101) meet processing requirements of the hydrosol solution;
• calculating and setting a flow rate of materials entering the processing pipeline (101) for each material property;
• and
• starting the mixing and shearing device (100) of the hydrosol solution preparation system, synchronously opening each of the feeding stations (300), transporting each material to the processing pipeline (101) according to the set flow rate, and simultaneously mixing and shearing all the materials by a first screw (102) in the processing pipeline (101) to obtain a homogeneous hydrosol solution.
