Problems solved by technology

[0002] In the market, passivated raw materials are usually used, that is, ordinary steel; and before the electrostatic spraying process, the base material does not undergo any pre-treatment process, and the electrostatic spraying process starts after the gold processing is completed, resulting in poor surface adhesion between the coating and the raw material , the product has been used for more than one year, and the powder and coating will fall off; the product's acid and alkali resistance, corrosion resistance, oxidation resistance, ultraviolet resistance, and surface self-cleaning performance are generally low

Embodiment Construction

[0039] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0040] Such as figure 1 Shown: the present invention discloses a production process of zinc steel guardrail, and its production process is:

[0041] (1) Inspection of the appearance and size of the base material, the appearance of the base material has no obvious rust, and the error of the base material thickness is ±0.2mm;

[0042](2) Substrate quality inspection, including: galvanized layer uniformity inspection, galvanized layer thickness inspection and galvanized layer adhesion inspection, among which the galvanized layer uniformity inspection refers to the use of copper sulfate solution for 4 dips in accordance with GB2694. The red spot of metal copper adhesion is qualified; the thickness inspection of galvanized layer refers to taking a sample section and weighing it by antimony chloride dezincificat...
