Degumming liquid

Abstract

The invention relates to a degumming solution and belongs to a chemical treatment solution, which is used for removing a fastening glue film adhering to the surface of mechanical parts. The invention provides a degumming solution that has a short degumming duration and has no corrosion to the mechanical parts. The invention consists of halogenated hydrocarbon, acetone, paraffin, white oil, a high molecular polymer and the latent solvent for the high molecular polymer. The degumming solution is characterized in that the weight percentage for the components is as follows: halogenated hydrocarbon 30 to 50 percent, white oil 4 to 10 percent, acetone 40 to 60 percent, high molecular polymer 0.05 to 0.1 percent, paraffin 0.5 to 2 percent and the rest is the latent solvent for the high molecular polymer.

Description

Technical field: [0001] The invention belongs to chemical treatment liquid and is mainly used for removing the fixed adhesive film adhered to the surface of mechanical parts. Background technique: [0002] At present, chemical adhesives are widely used in the processing of small mechanical parts. In order to improve production efficiency, some mechanical processing enterprises first bond small raw materials together with adhesives, and then cut them. It is difficult to separate the parts after cutting. It takes a long time to separate the parts by vibration, and the solid film remaining on the surface of the parts has a great influence on the phosphating or electroplating of the parts. Degumming is carried out by boiling with water, and the surface of metal parts is seriously corroded, which increases the burden of subsequent grinding. Invention content: [0003] The present invention aims at the above problems and provides a degumming solution with short degumming time a...
