Electrolytic reaction kinetic limitation
Low temperature slows the movement of water molecules and metal silver atoms on electrodes, slowing down the electrolytic ionization reaction, which directly reduces the amount of silver ions released per unit time.
Reduced bactericidal activity of silver ions
The chemical binding rate between silver ions and bacterial cell protein is positively correlated with temperature. Low temperatures greatly slow the adhesion of Ag⁺ to microbial membranes, extending the disinfection contact time required to achieve sterilization standards.
Increased water viscosity
Cold water has higher viscosity, which impedes the uniform diffusion of free silver ions in the pipeline water flow, resulting in uneven silver ion concentration locally and insufficient disinfection effect in partial areas.
Precipitation of mineral impurities
Calcium, magnesium and other mineral salts have lower solubility at low temperatures, and slight scaling is easily formed on the electrode surface, covering the conductive area of silver electrodes and further inhibiting electrolysis.
To solve the above problems, our silver ion sterilizer is equipped with a temperature sensing and automatic current boosting module, which compensates silver ion output according to water temperature to guarantee stable disinfection effect under low-temperature working conditions.
