Problems solved by technology

However, water-based metal cleaning agents are prone to foaming and residues. In severe cases, the foam overflows and takes away a large amount of surfactant, which shortens the life of the cleaning agent, and the foam will reduce the cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of cleaning, in particular to a preparation method of a cleaning agent with fast defoaming speed. Background technique [0002] After the metal workpiece is processed, the surface will carry dirt, such as various cutting fluids, guide rail oil, etc. If it is not cleaned, it will not only affect the smooth progress of the processing process, but also cause and accelerate the corrosion of the metal surface, affecting the processing quality and use of the product life. In addition, before finishing such as electroplating, phosphating (silanization), glaze coating, spray painting, etc., as well as in the repair and maintenance of mechanical equipment, the cleaning process is inseparable. The choice of cleaning process and the quality of the cleaning effect not only involve major issues such as safety, energy and environmental protection, but also directly affect the performance and quality of the product. There...
