Method for producing temp.-resistance, pressure-resistance oxide membrane aluminium wire and aluminium foil

Abstract

The invention relates to a manufacturing method for heat-proof pressure-proof aluminum wire aluminum foil. The technology process is that: taking softening and cleaning process to the bare aluminum wire aluminum foil or aluminum band, taking continuously anode oxidation by 100-1000HZ 38V AC voltage at 2.6 + / -0.3m / min in electrolytic tank electrolyte; putting into the solution made up of water, vitriol and oxalic acid to form 0.02-0.04mm A1203 oxide film, washing and drying. The invention has thick aluminum film, good heat proof pressure proof ability, low cost, high efficiency, good safety, and has great application prospect.

Description

1. Technical field [0001] The invention relates to a production method of aluminum wire and aluminum foil for winding electrical appliances, in particular to a production method of temperature-resistant and pressure-resistant oxide film aluminum wire and aluminum foil. 2. Background technology [0002] Aluminum wire and aluminum foil are commonly used materials in the production of electrical appliances, such as electric welding machines, general transformers, iron removers, electromagnets, rectifiers and other electrical equipment need to use aluminum wire and aluminum foil (tape) to wind the wire group, but in the process of use, these materials themselves It is not insulated. When using it, it needs to be coated with a layer of insulating material (such as insulating paint) or wrapped with a layer of insulating paper. In this way, the following problems will occur: [0003] 1. The temperature resistance and cost of insulating materials are important issues in the producti...

Problems solved by technology

[0006] In view of the above situation, the purpose of the present invention is to provide an improved production method of temperature-resistant and voltage-resistant oxide film aluminum wire and aluminum foil, which can effectively solve the problems of temperature and voltage resistance of oxide film aluminum wire aluminum foil or aluminum strip and reduce production costs. The technical solution is to soften and heat-preserve the aluminum foil or strip of the bare aluminum wire, decontaminate it with a purification solution, rinse it with water, and use 100-1000HZ (Hertz) AC 38V to work in the electrolyte of the electrolytic cell. Voltage, continuous anodic oxidation at a speed of 2.6±0.3m per minute for 2.5-3 minutes, after oxidation, place in a solution composed of water, sulfuric acid and oxalic acid to form a layer of 0.02-0.04mm Al 2 o 3 The oxide film can be rinsed and dried. The present invention is a scientific improvement to the original production method, and its product quality and performance indicators are more in line with actual needs, especially under new process conditions, especially with a working voltage of 100-1000HZ. The anodizing speed is fast, the aluminum film is thick, the temperature and pressure resistance performance is better, the cost is reduced, the work efficiency is improved, the electrical product is small in size, the performance is good, and it is safe to use.
