Working Principle:

Before introducing the working mechanism, let's first look at the scale formation process: at room temperature, calcium carbonate salts dissolve in water as positive and negative ions. When heated, changes occur. In heat exchange equipment, water continuously evaporates, and the concentration of insoluble salts in the water continuously increases. According to crystallization principles, when the concentration of solutes in water exceeds their solubility, if there are factors inducing nucleation (such as solid particles in the water or the pipe wall), crystals can precipitate. The crystallization rate is related to temperature. As the temperature rises, these insoluble crystal particles deposit on the inner wall of the pipeline and firmly bond together. Over time, these bonded substances gradually accumulate to form hard scale.
The microscopic mechanism of magnetic treatment involves the action of a magnetic field on substances, causing the molecular planes of diamagnetic substances to align perpendicular to the direction of the magnetic field. This alignment changes the molecular structure of the substance. As is well known, the main component of scale is CaCO3, and the temporary hardness salts in water are mainly Ca(HCO3)2.

Water molecules are strongly polar molecules. A water molecule is an isosceles triangle, and its diamagnetism is anisotropic. Magnetic treatment can change the structure of water molecules from tetrahedral to a planar arrangement along the flow direction. This liquid crystal-like regular arrangement reduces the density of water, thus decreasing its surface tension and increasing its permeability. The liquid crystal structure forms in the water rather than on the pipe wall, and the gelation rate exceeds the crystal growth rate. Consequently, the fine particles cut by the magnetic lines will suspend in the water in a colloidal form, and the flow of water can carry these crystal particles away. Thus, the opportunity for scale accumulation on the pipe wall is reduced, which is the basic principle of magnetic scale prevention.
