In spraying operations, the water curtain booth is a key piece of equipment for capturing overspray paint mist. However, substances such as paint resin and surfactants mixed into the circulating water can easily generate large amounts of foam. This stubborn foam not only overflows the water tank and pollutes the working environment, but also reduces the uniformity of the water curtain, lowering paint mist capture efficiency and causing paint residue to re-adhere to the workpiece surface, affecting spraying quality. Frequent water changes also increase wastewater treatment costs and downtime, becoming a difficult pain point for many spraying workshops.
In response to this series of problems, Chemi Tech, drawing on in-depth research into surface chemistry, has developed a high-efficiency defoamer specifically for spray water curtain booths. Featuring a specially designed formulation, this product rapidly penetrates and breaks foam films, defoaming quickly while providing long-lasting foam suppression. It is highly compatible with paint residues in the circulating water, does not affect water quality parameters, and does not deposit on the inner walls of equipment or in pumps, ensuring the long-term stable operation of the water curtain system.
Our solution is clear and easy to implement. Step one, diagnosis and analysis: our technical support staff can assist customers in analyzing the circulating water composition and the causes of foam. Step two, customized dosing: based on the tank capacity and foam severity, we recommend an appropriate defoamer dosage, usually requiring only a very low addition rate. Step three, continuous maintenance: we provide follow-up usage tracking and optimize the dosing plan to achieve the lowest cost and best results.
For example, a company in East China specializing in metal parts spraying found that its water curtain booth was flooded with foam after several hours of continuous operation, worsening paint mist treatment and affecting workpiece pass rates. After adopting the Chemi Tech defoamer, operators followed the guidance for the initial dosing, and the foam subsided rapidly within ten minutes. Subsequently, only a very small amount of defoamer was needed each day to keep the circulating water foam-free throughout the day. The water curtain regained its uniform curtain form, the paint mist capture rate improved significantly, the cleanliness of the workpiece surface was ensured, and the circulating water replacement cycle was extended several times, effectively reducing overall operating costs.
Choosing Chemi Tech means choosing not only a product, but also a reliable solution. We are committed to helping customers fundamentally resolve water curtain booth foam problems and improve the efficiency and stability of their spraying production lines.
