Description
Technical Field
The invention discloses a solution suitable for an aluminum alloy passivation process.
Background
Aluminum is a silver-white light metal, has ductility, can form a layer of oxide film that prevents metal corrosion in humid air, and the wide application of aluminium is in each field, and aluminium is comparatively easy to be oxidized in the air, receives the corruption, all will carry out passivation to the aluminum alloy before using usually, and among the prior art, because hydrofluoric acid has very big harm nature to the human body, and can release a large amount of harmful gas in the processing procedure, harm operating personnel's health and cause the pollution to the environment.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the solution suitable for the aluminum alloy passivation process, which avoids the harm of hydrofluoric acid to human bodies, does not release a large amount of gas harmful to the human bodies in the using process, reduces the environmental pollution, and is economic and efficient.
In order to achieve the purpose, the invention is realized by the following technical scheme: the solution suitable for the aluminum alloy passivation process comprises the following raw materials in percentage by weight: 0.5-6% of nitric acid, 10-35% of surfactant, 1-10% of surfactant, 0-3% of sodium fluoride, 0-2.5% of stabilizer, 5-20% of deionized water, 10-20% of amino acid and 30-60% of catalyst.
Has the advantages that: the product prepared by the method avoids the harm of hydrofluoric acid to human bodies, does not release a large amount of gas harmful to human bodies in the using process, reduces the environmental pollution, and is economical and efficient.
Detailed Description
