Description

Technical Field

[0002] Scale inhibitors are agents that can disperse sparingly soluble inorganic salts in water, prevent or interfere with the precipitation and scaling of sparingly soluble inorganic salts on metal surfaces, and maintain good heat transfer performance in metal equipment. Scale inhibitors for heat exchangers are formulated with epoxy resin and specific amino resins as base materials, with the addition of appropriate amounts of various rust-inhibiting and corrosion-inhibiting additives; they are single-component. They possess excellent shielding, impermeability, and rust-preventing properties, good scale inhibition and thermal conductivity, and excellent resistance to weak acids, strong alkalis, and organic solvents. They have strong adhesion, and the resulting film is bright, flexible, dense, and hard. Scale inhibitors are needed to disperse sparingly soluble inorganic salts in water during water treatment.

[0003] In existing technologies, the use of scale inhibitors requires them to be added to the equipment that needs to be descaled. In order to achieve the best descaling effect, the amount added often needs to be controlled within a certain range. If too little is added, it will not be able to effectively remove scale, while if too much is added, it will be wasteful and make subsequent cleaning more difficult. Existing quantitative dosing methods mostly rely on manual weighing and proportioning, which is complicated to operate, has a large error, and cannot meet the requirements of high precision. In addition, it is time-consuming and labor-intensive and requires frequent operation. Therefore, this application proposes a scale inhibitor adding mechanism to solve the above problems.
