Embodiment Construction

[0009] The present invention is described in detail below in conjunction with embodiment.

[0010] A method for anti-corrosion treatment of galvanizing inside a radiator, which is carried out according to the following steps:

[0011] a. Put the radiator body formed by welding the high-frequency welded pipe into the hydrochloric acid washing solution with a concentration of 29-30% for derusting treatment;

[0012] b. Heat and dry the radiator body that has completed the derusting treatment on a hot blast stove, and put it in 480°C molten zinc water for 10-20 minutes while it is hot for galvanizing treatment;

[0013] c. Put the galvanized radiator body into cold water to cool quickly. After observing that there are no air bubbles, a layer of tempered zinc layer integrated with the inner wall of the radiator body is formed on the inner wall of the radiator body.

Abstract

The invention relates to an anti-corrosion processing method that is applied into high-frequency welded tube radiators, in particular to a galvanizing and anti-corrosion processing method that is used inside the radiators, and is implemented according to following steps: a molded radiator billet is placed into a pickling liquor for implementing the processing of rust removing; the radiator billet that finishes the processing of rust removing is parched, and while the radiator billet is hot, the radiator billet is placed into a dissolved zinc solution with the temperature of 480 DEG C for 10 to 20 minutes so as to implement the processing of galvanizing; the radiator billet that finishes the processing of galvanizing is quickly placed into cold water for cooling, thus forming a toughened zinc layer on an inner wall of the radiator billet and integrating the toughened zinc layer with the inner wall into one, and as the toughened zinc layer is integrated with the radiator billet into one, the phenomenon that coatings of chemical engineering materials such as resin are easy to shed when heated can be avoided, and simultaneously the thickness of the radiator wall is increased; the density of toughened zinc is higher than the density of chemical engineering materials and the radiator billet, so the radiator has higher acid, alkali and corrosion resistance than the chemical engineering materials. Compared with radiators processed by traditional anti-corrosion techniques, the radiator that is processed by the galvanizing and anti-corrosion processing method of the invention has remarkably raised service life.

Description

Technical field: [0001] The invention relates to an anti-corrosion treatment method applied to high-frequency welded pipe radiators, in particular to a galvanized anti-corrosion treatment method inside the radiator. Background technique: [0002] The existing high-frequency welded pipe radiators are treated with internal resin chemical materials for anti-corrosion treatment. The disadvantages are: ①The production process of the radiators is to do anti-corrosion first and then paint. , will produce cracks, and the cracks will expose the radiator body, so it will not have anti-corrosion effect; The coating falls off, causing rust, corrosion and leakage inside the radiator, reducing the service life. Invention content: [0003] The present invention aims to solve the above disadvantages in the existing high-frequency welded pipe radiator anti-corrosion treatment method, and provides a galvanized anti-corrosion treatment method for radiators with metal zinc as anti-corrosion ...
