The invention discloses a method and a device for preventing and resisting scales based on quantum energy information recording, and a blank processing system, and relates to the technical field of pipeline system maintenance. The method for preventing and resisting the scales based on the quantum energy information recording includes the following steps: acquiring a water quality analysis reportof a water system; blending silicon powder, aluminum powder and magnesium powder proportionally; feeding the powder into a mold, and performing pressure casting to form a blank; heating the blank to the austenite temperature; superimposing a variable-frequency electromagnetic field on the blank; after cooling to the indoor temperature, removing the variable-frequency electromagnetic field; and putting the blank with quantum potential energy of electron relaxation in a water system. The method is easy to implement, low in cost, environmentally friendly and safe, and can prevent polar moleculesfrom gathering on the inner wall of the water system to form the scales. The blank processing system with the quantum potential energy of the electron relaxation is used for processing the blank withthe quantum potential energy of the electron relaxation. The blank is applied to the water system, and can effectively prevent and resist the scales. The device for preventing and resisting the scaleshas a simple structure and a low operational cost.
