Chemi Tech Acid-Alkali Resistant Defoamer: Effectively Solving Foam Challenges in Strong Acid and Alkali Environments

In chemical processing, electroplating, industrial cleaning and other fields, foam problems in strong acid and alkali environments have long plagued production enterprises. Foam can lead to reduced production efficiency, increased product defects, and even equipment operational abnormalities. Traditional defoamers tend to deactivate and decompose in extreme pH environments, unable to function continuously.

Chemi Tech specializes in the development of acid-alkali resistant defoamers, adopting special modified silicon polymers and hydrophobic particle composite technology. This enables the defoamer to maintain structural stability within the pH range of 1-14. Its molecular chains can rapidly penetrate foam liquid films, achieving instant bubble breaking by reducing surface tension, and forming a persistent protective layer on the liquid surface to prevent foam regeneration.

Application case: An electronic materials enterprise encountered severe foam overflow in concentrated hydrochloric acid during etching processes, leading to chemical solution spillage and process parameter. After adopting Chemi Tech's KM-218 series defoamer, a three-step solution was implemented: first, on-site foam characteristic analysis determined the dosage at 0.15%-0.3%; second, uniform dispersion was achieved through the circulation system; finally, an automatic replenishment mechanism was established to maintain effective concentration. This resulted in 98% foam elimination率 and a 5 percentage point reduction in product defect rate, saving approximately 300,000 yuan annually in cleaning and maintenance costs caused by foam.

Our technical team provides full-process support, from site survey and pilot testing to large-scale application, ensuring defoaming solutions precisely match working condition requirements. Chemi Tech defoamers have been successfully applied in 37 specific scenarios, helping customers achieve production process optimization and cost control.
