Problems solved by technology

Galvanized water pipes have the advantages of high strength and low cost, but they are prone to rust during long-term use, polluting water quality, and cannot meet the requirements for drinking water. The subsidence of the underground has caused great harm to society.
Plastic water pipes (including PPR water pipes, PVC water pipes, etc.) are cheap and easy to install, but the temperature range of such water pipes is extremely limited. When the temperature is too high or too low, brittle cracks will appear, which increases the difficulty of maintenance. The inner wall is easy to breed bacteria, and long-term use will have adverse effects on human health
Stainless steel water pipes have the characteristics of corrosion resistance and high temperature resistance, but their spare parts usually need to be welded. After long-term use, water leakage is prone to occur. The construction is difficult and the cost is too high to be recognized by the society.

Abstract

The invention belongs to the technical field of aluminum alloy surface treatment. The invention provides an aluminum alloy surface oxidation treatment method and an aluminum alloy ceramic water pipe. According to the aluminum alloy surface oxidation treatment method, a compact and uniform ceramic layer can be formed on the surface of an aluminum alloy, and the ceramic layer is high in hardness, high in wear resistance, high in breakdown voltage resistance, low in porosity, high in adhesive force, large in thickness and free of cracking and aging after being used for a long time; and corrosion resistance is achieved, high temperature resistance is achieved, the chemical property is stable, and good biological safety is achieved. According to the surface oxidation treatment method, the surface treatment plasticity of an aluminum alloy pipe is high. Due to the fact that an aluminum oxide film layer is arranged on the inner wall of the aluminum alloy ceramic water pipe, the good sealing performance and chemical stability are achieved, the biological safety performance is excellent, the food hygiene level can be reached, and the aluminum alloy ceramic water pipe can be widely applied to water supply and drainage pipelines, gas pipelines, heat distribution pipelines or chemical containers and can also be applied to fireproof building materials.

Description

technical field [0001] The application belongs to the technical field of aluminum alloy surface treatment, and in particular relates to an aluminum alloy surface oxidation treatment method and an aluminum alloy ceramic water pipe. Background technique [0002] At present, common water supply and drainage pipes are divided into galvanized water pipes, plastic water pipes and stainless steel water pipes. Galvanized water pipes have the advantages of high strength and low cost, but they are prone to rust during long-term use, polluting water quality, and cannot meet the requirements for drinking water. The subsidence of the underground has caused great harm to society. Plastic water pipes (including PPR water pipes, PVC water pipes, etc.) are cheap and easy to install, but the temperature range of such water pipes is extremely limited. When the temperature is too high or too low, brittle cracks will appear, which increases the difficulty of maintenance. The inner wall is easy...
