Abstract

The invention discloses a method for rapidly and effectively removing an HW61-1 paint layer. The method comprises the following steps of firstly, removing oil stains on the surface of a part by adopting an oil removal solution, cleaning by hot water to remove traces of the oil removal solution on the surface of the part, removing paint by using a paint removal solution, and then removing oil, cleaning by the hot water, blow-drying and drying. By using the method provided by the invention, the solution or medium in the previous process cannot pollute the solution in the subsequent process, in order to enable the part to be in a relatively clean state, the oil removal solution needs to dissolve the oil stains on the surface, cleaning is thorough, it can be guaranteed that the paint layer on the surface of the part and the solution have a certain reaction, by means of the method, the HW61-1 paint layer can be completely decomposed and removed, high efficiency and safety are achieved, the engine manufacturing and repairing period can be shortened, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of HW61-1 paint layer removal, and relates to a method for quickly and effectively removing the HW61-1 paint layer. Background technique [0002] The surface of ultra-high-strength steel shaft parts of aero-engines is coated with HW61-1 paint layer, which is a kind of epoxy organosilicon aluminum powder paint. When the paint layer has defects that do not meet the design requirements during the production process or after use, Paint needs to be removed and reapplied. Removal by mechanical methods will cause damage to the surface of the parts. Currently, the commonly used technical method is to use acetone to remove. However, when the method of soaking in acetone is used to remove, there are problems such as long cycle time, potential safety hazards and inability to completely remove. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-menti...
