Problems solved by technology

However, the chemical properties of aluminum are relatively active, and it is easy to corrode in acid, alkali, and salt solutions. Due to the small diameter, long pipeline, and complex structure of aluminum heat exchangers, traditional aluminum surface treatment technologies such as electroplating and anodic oxidation , are difficult to deal with on the inner wall of the pipeline, so that the aluminum heat exchanger of the gas water heater will accelerate the aluminum heat exchange during use, especially in places with poor water quality, such as when the water quality is acidic, alkaline and hard. Corrosion of the aluminum heat exchanger will cause problems such as corrosion and perforation of the aluminum heat exchanger and water leakage failure, which reduces the service life of the product

Example Embodiment

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: An aluminum heat exchanger pipeline with an anti-corrosion coating on the inner wall is provided with an anti-corrosion coating made of liquid paint on the inner wall of the pipeline. The liquid paint can be water-based paint or oil-based paint. The liquid paint in this embodiment is Water based paint. The processing method of the above-mentioned pipeline sequentially includes the steps of pre-treatment, painting in the pipe, and curing, and the details are as follows:

[0020] Step 1: Pre-treatment (chemical cleaning).

[0021] 1. Use a pressure pump to inject the acid cleaning agent (mixed acid solution, the main components are hydrofluoric acid, sulfuric acid, nitric acid, surfactant, etc.) from one end of the aluminum heat exchanger pipeline, and flow out from the other end, and use the pressure after the outflow. The water pump continues to maintain a circulating flow time of 1 to 3 minutes, so that the cleaning agen

Abstract

The invention discloses an aluminum heat exchanger pipeline of which the inner wall is provided with an anticorrosive coating. The anticorrosive coating made of liquid paint is arranged on the inner wall of the pipeline. A processing method of the pipeline includes the steps of preprocessing, pipeline interior painting, curing and the like. Water is prevented from directly making contact with the aluminum surface of the inner wall of the aluminum heat exchanger pipeline through the anticorrosive coating, base materials on the inner wall of the pipeline is protected, the pipeline can be effectively prevented from corrosion perforation by poor-quality water, and therefore the service life of an aluminum heat exchanger is prolonged.
