The amount of foam produced by a degreasing agent is often used to measure its degreasing ability, but the use of low-foaming cleaning agents is increasing in modern industrial and domestic cleaning. There are two methods to achieve low-foaming requirements for cleaning agents: one is to add defoamers to the cleaning agent; the other is to use low-foaming surfactants, such as polyether surfactants. However, the defoaming ability of cleaning agents containing defoamers often decreases over time.
In the electroplating industry, the base metal must be degreased before electroplating. If the degreasing agent produces excessive foam, it will affect the production process.
Degreasing is a critical step before electroplating and coating of metal parts, and the degreasing effect directly affects the quality of the plating and coating. Traditional processes such as high-temperature chemical degreasing, organic solvent degreasing, electrochemical degreasing, and high-temperature alkaline degreasing are gradually being replaced by water-based metal oil stain cleaners due to high cost, high energy consumption, heavy pollution, and poor operating environment.
