Problems solved by technology

Due to the relatively active nature of aluminum, a dense aluminum oxide film is formed on the surface when high temperature is applied during the forming process. At the same time, aluminum and aluminum alloy materials will be contaminated with a lot of oil, dust and other pollutants during transportation and storage. The existence of oil stains will adversely affect many processes such as subsequent coating of aluminum materials

Abstract

The invention provides an aluminum cleaning agent. The aluminum cleaning agent is prepared from components in percentage by weight as follows: 10%-15% of phosphate, 10%-15% of citric acid, 7%-9% of ammonium fluorate, 7%-9% of phytic acid, 5%-8% of OP-10 and the balance of water. The invention also provides a preparation method and a use method of the aluminum cleaning agent. The aluminum cleaningagent can effectively remove oil stains and residues on the surface of an aluminum metal material, form films on the surface of the aluminum metal material uniformly, the surface of the aluminum metalmaterial is not obviously corroded after washing, and the aluminum cleaning agent is quick in oil removal and good in stability. Besides, the preparation and use methods of the aluminum cleaning agent are simple and easy to operate and facilitate mass production.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an aluminum lotion and its preparation and use method. Background technique [0002] Aluminum is one of the most widely used non-ferrous metals. It has the characteristics of light weight, high mechanical performance, good thermal and electrical conductivity, and corrosion resistance in the atmosphere. It is widely used in petroleum, aviation and light industry and other fields. Due to the relatively active nature of aluminum, a dense aluminum oxide film is formed on the surface when high temperature is applied during the forming process. At the same time, aluminum and aluminum alloy materials will be contaminated with a lot of oil, dust and other pollutants during transportation and storage. The existence of oil stains will adversely affect many processes such as the subsequent coating of aluminum materials. [0003] The existing aluminum lotions generally have...
