锌钢格板尽管各方面的性能都很杰出,可是如果在生产过程中和后期贮存出现了问题,便会造成镀锌钢格板生白锈,严重影响了使用寿命。

Although the performance of galvanized steel grille is excellent in all aspects, if there are problems in the production process and later storage, it will cause white rust of galvanized steel grille and seriously affect its service life.

一、涂油

First, oiling.

在镀锌钢格板上涂油,隔绝空气和锌。这种方式较简略,可是能够很好地起到避免生锈的效果,

Oil on galvanized steel grille to insulate air and zinc. This method is relatively simple, but can play a good role in avoiding rust.

二、磷酸盐

Phosphates

镀锌钢格板外表涂漆会防锈,那么用磷酸盐皮膜处理很合适。磷酸盐会紧紧附在镀锌表层构成疏松多孔结构,能够给油漆提供很好的立足点。

Galvanized steel grille surface paint will be rust-proof, so phosphate coating is suitable. Phosphates adhere tightly to the galvanized surface to form porous structure, which can provide a good foothold for paint.

三、铬酸

Three. Chromic acid

把镀锌钢格板浸入铬酸系溶液中,外表会构成活性低的薄膜,就算这层膜被损坏,周围的铬酸盐溶于水后会在损伤部位重新组成新膜。对避免白锈的产生很有用。

When galvanized steel lattice plate is immersed in chromic acid solution, it will form a thin film with low activity. Even if the film is damaged, the surrounding chromate will be dissolved in water to form a new film at the damaged area. It is very useful for avoiding white rust.

除了对镀锌钢格板作外表处理之外,也要留意日常的贮存方式,比如贮存的场所要防水防潮、通风杰出、温差不大等。这样能够防备镀锌钢格板生白锈。

In addition to surface treatment of galvanized steel grilles, attention should also be paid to daily storage methods, such as waterproof and moisture-proof storage places, excellent ventilation, small temperature difference, etc. This can prevent galvanized steel grille from white rust.
