[0018] After the above treatment of the cold stripping agent solution, it was found that the oil stain on the surface of the workpiece was originally removed, and the surface of the workpiece was free from any corrosion.
- the ingredients are mixed according to the following parts by weight: 35 parts of toluene, 25 parts of xylene, 12 parts of alkylphenol ethoxylate, 6 parts of nonylphenol ethoxylate, 24 parts of isopropanol, 20 parts Methanol, stirred, mixed evenly, formulated as a cold release agent.
- Treatment method preparing cold release agent; dissolving cold release agent in water to prepare cold release agent solution, the mass percentage of cold release agent in cold release agent solution is 12%; soaking metal workpiece in cold In the stripping solution (in the treatment tank), after 15 minutes of treatment, the metal workpiece is washed with water.
- the ingredients are mixed in the following parts by weight: 40 parts of toluene, 30 parts of xylene, 15 parts of alkylphenol ethoxylate, 8 parts of nonylphenol ethoxylate, 30 parts of isopropanol, 25 parts Methanol, stirred, mixed evenly, formulated as a cold release agent.
- Treatment method preparing a cold release agent; dissolving the cold release agent in water to prepare a cold release agent solution, wherein the mass percentage of the cold release agent in the cold release agent solution is 15%; soaking the metal workpiece in the cold In the stripping solution (in the treatment tank), after 20 minutes of treatment, the metal workpiece is washed with water.
- the ingredients are mixed in the following parts by weight: 60 parts of toluene, 40 parts of xylene, 20 parts of alkylphenol ethoxylate, 10 parts of nonylphenol ethoxylate, 40 parts of isopropanol, 30 parts Methanol, stirred, mixed evenly, formulated as a cold release agent.
- Treatment method preparing cold release agent; dissolving cold release agent in water to prepare cold release agent solution, the mass percentage of cold release agent in cold release agent solution is 10%; soaking metal workpiece in cold In the stripping solution (in the treatment tank), after 30 minutes of treatment, the metal workpiece is washed with water.
