A paint remover for steel-aluminum composite material
This invention discloses a paint remover for steel-aluminum composite materials, belonging to the field of metal material surface treatment technology. It comprises the following components in weight percentages: 5%-8% alkaline substance; 5%-10% lipase component; 10%-16% solvent; 5%-10% surfactant; 6%-13% co-solvent; 5%-8% corrosion inhibitor; and water as the balance. The paint remover is prepared from alkaline substance, lipase component, solvent, surfactant, co-solvent, corrosion inhibitor, and water. It is used for removing paint from steel-aluminum composite materials. On one hand, the alkaline substance saponifies some groups in the paint, dissolving them in the solvent and water. On the other hand, heating and steaming the paint film reduces its strength and adhesion to the metal. Then, utilizing the wetting, penetration, and affinity effects of the surfactant, the catalytic effect of the lipase component, and the protective effect of the corrosion inhibitor on the steel-aluminum substrate, the goal of removing paint quickly without corroding the substrate is achieved.

A method for soldering aluminum enameled wire in a shaded-pole motor
This application discloses a method for soldering aluminum enameled wire in a shaded-pole motor. The method involves simultaneously winding both the un-removed and removed portions of the aluminum enameled wire's terminals onto the lead wire core to form a connection structure. This increases the stress-bearing area of the aluminum enameled wire during the connection process, helping to distribute the pressure on the removed portions and increasing the tensile strength of the wire. By using lead-free solder bars and aluminum flux as raw materials in a soldering furnace to solder the connection structure, tinning becomes easier, resulting in a more uniform, full, and immersion-free solder joint, improving tinning effect and efficiency. The use of a heat-sealed double-walled tube to seal the solder joint prevents oxidation and brittle fracture caused by prolonged exposure to air. Multiple cleaning steps remove residual paint remover from the removal process and residual flux from the soldering process, preventing these residues from oxidizing the solder joint and causing brittle fracture.
