Abstract

The invention discloses an anodic oxidation process for an obstruction anti-explosion aluminum alloy which is used in a flammable and combustible liquid or gas reservoir as a safety filling material in the metal material machining field. A machined and formed aluminum alloy net-shaped obstruction anti-explosion material is arranged in a 15-25% sulfuric acid basin; an anode is connected with the to-be-oxidized obstruction anti-explosion material; a cathode is connected with a stainless steel plate which does not generate ions; a direct-current power supply is connected between the anode and the cathode; the direct-current voltage is 12-36V; anodic oxidation can be anodic oxidation performed on the surface of an aluminum alloy thin plate; the thickness of an oxidized layer of the aluminum alloy is increased through anodic oxidation, and the hardness and pressure-resistance of the material are improved. The anodic oxidation process has the advantages that the hardness of the aluminum alloy obstruction material is greatly improved, the acid-base corrosion resistance and the mechanical strength are improved, and the like. On the basis of the process, the quality of the existing aluminum obstruction material can be greatly improved due to added electric adhesion and electrophoresis processes.

Description

technical field [0001] The invention relates to the field of metal material processing, in particular to a barrier explosion-proof aluminum alloy anodic oxidation process used as a filling material in an inflammable and explosive liquid or gas storage. Background technique [0002] The barrier explosion-proof technology is to effectively prevent the explosion of flammable, explosive, gaseous and liquid hazardous chemicals caused by accidents (static electricity, welding, gunshots, collisions, wrong operations, etc.) Intrinsically safe proprietary technology in the storage and transportation of gaseous hazardous chemicals. [0003] At present, the barrier and explosion-proof products on the market are basically made of aluminum alloy. The barrier materials of aluminum alloy are mostly used for gasoline and diesel; liquefied petroleum gas, liquefied natural gas and other flammable and explosive materials with low corrosion and low working pressure. It is character...
