In spray painting operations, the water curtain booth is the key equipment for capturing overspray paint mist. However, the paint, impurities and additives mixed into the circulating water readily generate large amounts of stubborn foam. This foam not only overflows the booth, polluting the working environment and spoiling the appearance of the equipment, but also clogs the water pump and pipelines, reducing paint mist capture efficiency, leading to lower coating quality, and even triggering equipment shutdowns and increasing unnecessary cleaning and maintenance costs.
To address this pain point, drawing on in-depth research into surface chemistry, Chemi Tech has launched a defoamer designed specifically for water curtain booth circulating water systems. The product can quickly penetrate the foam film, reduce local surface tension and prompt the foam to rupture. Its unique molecular structure allows it to disperse well in water and resist interference from paint and impurities, maintaining long-lasting defoaming and foam suppression capability and effectively responding to repeated foam generation.
Our solution is specific and easy to operate: first, analyze the foam characteristics and water quality of your water curtain booth circulating water; second, recommend a suitable Chemi Tech defoamer model and initial addition ratio; then, guide you to dose at the water inlet of the circulation tank or in the foam accumulation area, where usually an addition ratio of just 0.05%-0.3% is enough to be effective; finally, we will provide follow-up tracking and optimize the addition plan according to the foam control situation to ensure long-term stable operation.
For example, at an auto parts manufacturer located in East China, the water curtain booth on its spray painting line had long been troubled by foam overflow and required daily shutdowns for cleaning. After using the Chemi Tech defoamer and operating according to the recommended steps, the foam subsided rapidly within minutes of addition, and the subsequent foam suppression effect remained stable. This restored the water curtain booth's normal paint mist treatment function, made the working environment clean, greatly reduced equipment maintenance frequency, and significantly safeguarded the continuous production capacity of the spray painting line.
Choosing Chemi Tech is not only choosing a product but also choosing a reliable foam control solution. We are committed to helping customers optimize water curtain booth performance, improve production efficiency and create cleaner, more efficient working environments.
