[0002] Currently, thickening agent is often used in industrial production, and the thickening agent is a kind of compound with thickening and thickening ability, which can interact with molecules in liquid, such as hydrogen bond, hydrophobic interaction, electrostatic interaction, etc., so as to construct a three-dimensional network structure, reduce the fluidity of liquid, and make it more viscous. These thickening effects can be used to change the rheological properties of objects, including viscosity, fluidity and setting time, etc., so as to affect the specific properties and applications of the substance. At present, in the preparation of acidification with thickening agent, agitating unit is often needed to stir several liquid materials uniformly. The current agitating unit usually sets a rotating stirring shaft in the stirring tank.
