Precision Defoaming Solution for Degreasers by Chemi Tech

In the field of industrial cleaning and metal pretreatment, the degreasing process is a critical step to ensure the quality of subsequent operations. However, degreasers often generate massive persistent foam during use due to surfactant action, mechanical agitation, and temperature variations. This foam not only causes tank overflow, leading to material waste and site contamination, but also severely shields workpiece surfaces, impairing degreasing efficiency and resulting in issues like inadequate cleaning and poor coating adhesion. Effectively controlling foam has become a pressing challenge for many manufacturers.

Addressing foam issues in degreasing processes, Chemi Tech has developed a series of high-performance defoamers specifically for degreasers, based on in-depth research in surface chemistry. Our solution is not simply adding generic agents but involves a comprehensive analysis of the client's specific degreasing system (e.g., alkaline, acidic, or solvent-based). First, our technical team evaluates the root causes of foam, such as formulation components, operating temperature, spray pressure, or circulation intensity. Then, we select the most compatible defoamer type. Our products offer both rapid foam knockdown and long-lasting foam suppression, maintaining stable performance even under high temperature, strong alkali, or high-shear conditions.

The implementation process is clear and efficient: Step 1, Problem Diagnosis & Sample Matching. Clients provide degreaser samples and process parameters; we conduct lab simulation tests and recommend the most suitable defoamer. Step 2, Pilot & Scale-up Testing. On-site small-batch trials confirm defoaming effectiveness and ensure no adverse impact on degreasing performance. Step 3, Determining Optimal Dosage & Addition Method. Provide detailed dosage guidance; typically, a very low addition ratio yields significant results. Step 4, Continuous Follow-up & Optimization. Establish long-term service to ensure defoamer stability in prolonged production.

We served a precision component manufacturer in East China. Their alkaline degreasing line for aluminum alloy parts faced severe foam overflow, causing slippery workshop floors and incomplete degreasing in part recesses. After applying Chemi Tech's tailored defoamer, foam was significantly suppressed within minutes, the tank solution became calm, and overflow ceased. Inspection confirmed workpiece cleanliness met standards, and the defoamer did not affect the degreaser's cleaning power or tank stability. This production line has been operating stably for over eighteen months, with improved efficiency and product yield.
