Problems solved by technology

In addition, Japan produces insulating aluminum shells, and the outer layer is made of PET or resin materials. The insulating film is easy to break when used, and it is easy to fall off when washed with water. The insulating film will turn yellow after soldering and high temperature and will shrink and release the film after a second time.
Abnormal short-circuit quality of the finished product without insulating film on the inner layer of the aluminum shell still occurs

Embodiment Construction

[0017] In this creation, polyacryl resin and polyurethane synthetic material particles are added to the solution. After the additive is added to the solution, the material particles in the solution will be coated to make them negatively charged. When the negative charge is subjected to the force of the electric field, it will move to The anode is attached to the surface of the attachment, and the material particle additive can also be added to the solution to coat the material particles in the solution to make it positively charged. When this positive charge is subjected to the force of the electric field, it will move to the cathode attachment. surface for attachment.

[0018] After the additive is added to the solution, the material particles in the solution will be coated to make them negatively charged. When the negative charge is subjected to the force of the electric field, it will move to the surface of the anode to be attached for attachment. Under constant voltage, th...

Abstract

The present invention relates to a method of manufacturing an environmental-friendly insulated aluminum case for aluminum electrolytic capacitors and lithium batteries. The method satisfies appearance and insulation property requirements of the aluminum electrolytic capacitors, the lithium batteries and ordinary batteries; reduces environmental pollution caused by waste gas generated from burning used PVC and PET; and reduces plant energy consumption and costs, and manufacturing processes. An insulation film is coated on the inner cylinder surface of a cylinder of a workpiece, thereby preventing abnormity of short circuit caused by the contact between a placed part and the cylinder, and improving quality and efficiency.

Description

technical field [0001] The invention relates to a general aluminum electrolytic capacitor, a lithium battery, and a general battery. The inner and outer surfaces of a cylindrical container workpiece processed by metal materials are covered with a layer of 8-16 μm insulating film, which meets the insulation characteristics of the aluminum electrolytic capacitor, lithium battery, and general battery. Background technique [0002] It is currently known that general aluminum electrolytic capacitors and lithium batteries, general battery outer container cylindrical parts use materials, aluminum electrolytic capacitors use aluminum materials, lithium batteries and general batteries are useful aluminum and tinplate materials, and the aluminum materials and tinplate materials are made of round The raw materials of cylinder container workpieces are metal conductive materials, so aluminum electrolytic capacitors, lithium batteries, and general batteries are prone to short-circuit quali...
