In industrial sectors such as metal processing and equipment cleaning, strong alkaline cleaners are widely used for their excellent degreasing and cleaning capabilities. However, under mechanical agitation, high temperature, or in systems containing surfactants, they are prone to generating large amounts of persistent foam. This foam not only overflows, causing raw material waste and environmental concerns, but also severely obscures workpiece surfaces, leading to cleaning blind spots and affecting subsequent process quality. Furthermore, foam entrainment reduces the effective volume of the cleaning tank, slowing down overall production efficiency.
Addressing these common industry pain points, Chemi Tech has developed a series of specialized defoamers for highly alkaline environments based on years of technical expertise. The core advantage of our products lies in their exceptional chemical stability, maintaining activity over extended periods in high pH conditions (typically up to 14) without being easily decomposed or saponified by the strong alkali. Their foam suppression is long-lasting, effectively inhibiting foam generation throughout the entire cleaning process, rather than providing only a temporary break of existing foam.
The specific solution and addition steps are as follows: First, conduct an on-site assessment to determine the specific stage and severity of foam generation. Second, based on the cleaner formulation, operating temperature, and circulation intensity, recommend the appropriate Chemi Tech defoamer type and initial dosage, generally suggested between 0.1% and 0.5% of the total cleaning solution volume. During addition, it can be slowly dripped directly into the tank under agitation for even dispersion. For systems with continuous foam generation, a top-up approach with small, frequent additions is recommended to maintain optimal foam suppression. After application, rapid foam collapse and prolonged suppression are visibly observed, leading to more complete contact between the cleaning solution and workpieces, and significantly improved tank solution utilization.
We served a component manufacturing enterprise in East China. The company frequently experienced foam overflow issues during its high-temperature strong alkaline degreasing process, requiring line stoppage for cleanup several times per shift, and parts often showed stains due to foam residue after cleaning. After implementing a customized Chemi Tech defoaming solution, foam was controlled instantly and persistently. The frequency of production line stoppages for cleanup drastically reduced, the first-pass yield of products improved, and approximately 15% of cleaner loss due to overflow was reduced, delivering comprehensive benefits highly recognized by the client.
Choosing Chemi Tech means selecting not just a defoaming product, but a systematic efficiency-enhancing solution for foam problems in strong alkaline cleaning. We are committed to supporting our customers in achieving more efficient, economical, and stable cleaning production through professional products and technical services.
