Solving Foam Challenges in Painting Shop Water Treatment: Chemi Tech's Efficient Defoamer Solutions

In the production process of painting shops, the water treatment system is a critical link for ensuring process stability and wastewater compliance. However, factors such as residual pretreatment chemicals, surfactant buildup, and high-speed agitation in circulating water systems often lead to the generation of abundant and persistent foam. This foam not only overflows from tanks, contaminating the work environment, but can also severely impact paint quality, causing defects like craters and fisheyes in coatings. Furthermore, foam reduces water treatment efficiency and increases downstream processing costs.

Addressing this common industry pain point, Chemi Tech has conducted in-depth research and developed a highly targeted series of specialized defoamers for painting shop water treatment. Our solution is not simply about adding generic chemicals but is based on a thorough analysis of the painting process water quality.

The specific resolution steps are clear and defined. Step one: Diagnosis and Analysis. Our technical support team conducts on-site or sample analysis to identify the root cause of foam generation, whether it stems from degreasers, phosphating agents, or resin residues. Step two: Selection and Matching. Based on water characteristics (such as pH, temperature, system composition), we select the most suitable product model from the Chemi Tech defoamer portfolio, ensuring both rapid foam breaking and long-lasting foam suppression. Step three: Precise Dosing. We guide customers to determine the optimal dosing point (e.g., circulating water tank, overflow tank, or specific process stage) and dosage to achieve the best results at minimal cost. Step four: Effect Tracking and Optimization. We provide follow-up services to adjust the plan according to system changes, ensuring long-term stability.

We once served an enterprise specializing in metal part painting. The circulating water tank in its pretreatment line accumulated degreasers, generating massive stubborn foam daily, requiring frequent cleaning by workers and leading to an increase in defective painted workpieces. After implementing Chemi Tech's tailored defoamer solution, foam was significantly controlled within 24 hours of dosing. The area around the tank became clean, and painting quality returned to normal. System operational stability improved, also reducing water waste and excessive chemical consumption caused by foam.

Choosing Chemi Tech means selecting not just a product, but a reliable systematic solution. We are committed to helping painting shops overcome the persistent challenge of water treatment foam, enhancing overall production efficiency and quality control levels for smoother and more economical operation.
