Cleaning effect of acidic cleaning fluid: Acidic UV cleaning fluid has a significant effect on removing oxides, rust, etc. from metal surfaces. Its acidic component can react chemically with metal oxides, converting insoluble oxides into soluble salts, which are easier to clean with the assistance of ultraviolet light. For example, for the patina on the surface of copper products, acidic cleaning solutions can quickly dissolve and restore the brightness to the surface, and ultraviolet rays accelerate the reaction process and improve cleaning efficiency.
The potential impact of acid on the objects to be cleaned: However, if the concentration of the acidic cleaning solution is too high or the cleaning time is too long, it may cause corrosion to some metal materials. For active metals such as aluminum and zinc, an acidic environment will accelerate their dissolution, causing damage to the surface of the object to be cleaned, affecting its performance and appearance. Even for corrosion-resistant metals, long-term exposure to acidic cleaning solutions can cause microstructural changes that reduce the material's durability.
Cleaning advantages of alkaline cleaning fluid: Alkaline UV cleaning fluid performs well in removing oil, organic matter and other pollutants. Alkaline substances can saponify grease and convert it into water-soluble substances for easy cleaning. Under ultraviolet irradiation, this reaction rate is accelerated and oil stains can be removed more thoroughly. For example, when cleaning stubborn oil stains on the surface of kitchen equipment, alkaline cleaning fluid combined with ultraviolet cleaning is very effective.
The effect of alkaline on the objects to be cleaned: Alkaline cleaning fluid is more friendly to glass, ceramics and other materials and generally does not cause obvious corrosion. However, for some metals that are not resistant to alkali, such as tin, lead, etc., the alkaline environment may cause the formation of alkaline salts on the surface, affecting its gloss and conductivity. Moreover, if the alkaline cleaning solution remains on the surface of the equipment, it may form white crystals after drying, affecting the appearance and subsequent use.
Characteristics of neutral cleaning fluid: The pH of neutral UV cleaning fluid is close to 7, which is relatively mild. It is suitable for materials that are sensitive to pH, such as certain electronic components, optical lenses, etc. Under the action of ultraviolet rays, neutral cleaning fluid removes pollutants mainly through physical effects, such as dissolution and dispersion. It can ensure the cleaning effect while minimizing damage to the objects being cleaned.
The importance of pH balance: In order to achieve the best cleaning effect and protect the objects to be cleaned, it is necessary to select a cleaning solution with appropriate pH based on the material of the objects to be cleaned and the type of contaminants. At the same time, controlling conditions such as cleaning time and temperature is also critical. For example, for cleaning precision instruments, it may be necessary to use a neutral cleaning solution for preliminary cleaning, and then select a weakly acidic or weakly alkaline cleaning solution for targeted treatment based on the residual contaminants.
Monitor and adjust pH: During the use of UV cleaning fluid, the pH of the cleaning fluid should be monitored regularly. As the cleaning process proceeds, the pH in the cleaning solution may change due to the neutralization of contaminants. By adding an appropriate amount of acid-base regulator, the pH of the cleaning solution is maintained within a suitable range, ensuring the stability and consistency of the cleaning effect and extending the service life of the cleaning solution.
