热镀锌钢格板白锈等后期的维护措施

来源:http://www.jnxxjm.com

热镀锌钢格板是指将钢格板焊接完成后表面进行热镀锌防腐处理,一般钢格板的表面处理方式有:热镀锌,冷镀锌,喷漆防锈漆,其中热镀锌防腐效果好,价格也高,但却是人们常用的钢格板,热镀锌人们常称为“热浸锌”,热镀锌钢格板又称福州热浸锌钢格板。

Hot-dip galvanized steel grille refers to hot-dip galvanizing and anticorrosive treatment on the surface of steel grille after welding. Generally, the surface treatment methods of steel grille include hot-dip galvanizing, cold-dip galvanizing and spray paint. Among them, hot-dip galvanizing has the best anticorrosive effect and high price, but it is the most commonly used steel grille. Hot-dip galvanizing is often called "hot-dip galvanizing". "Hot-dip galvanized steel grating is also called Fuzhou hot-dip galvanized steel grating.

要延长热镀锌钢格板的使用寿命,除了在安装热镀锌钢格板时对安装的技术要求比较高外,我们还要注意热镀锌钢格板在安装完成后的定期维护问题。

In order to prolong the service life of hot-dip galvanized steel grilles, we should pay attention to the regular maintenance of hot-dip galvanized steel grilles after installation, besides the high technical requirements for installation when installing hot-dip galvanized steel grilles.

在热镀锌钢格板使用中要定期清理表面赃物,尤其是化工厂类,强酸,强碱等等极易损害钢格板表面的锌层,钢格板本身的防腐性能并不高,当钢格板表面锌层脱落后,钢格板很快就会被腐蚀,逐渐失去作用,所用保护热镀锌钢格板表面锌层是钢格板后期维护的重中之重,其次,热镀锌钢格板的硬度根据材质的不同也会有所不同,在使用当中,应尽量避免过载负荷,要根据热镀锌钢格板的使用规格,给予其合适的负载。

In the use of hot-dip galvanized steel grille, it is necessary to regularly clean up the surface booty, especially in chemical plants, strong acid, strong alkali and so on. It is very easy to damage the zinc layer on the surface of the steel grille. The corrosion resistance of the steel grille itself is not high. When the zinc layer on the surface of the steel grille falls behind, the steel grille will soon be corroded and gradually lose its role in protecting the hot-dip galvanized steel grille. The zinc layer on the surface of the steel grille is the most important thing in the later maintenance of the steel grille. Secondly, the hardness of the hot-dip galvanized steel grille varies according to the different materials. In use, overload should be avoided as far as possible, and appropriate load should be given according to the specifications of the hot-dip galvanized steel grille.

任何产品,都是有使用寿命的,为什么同样的产品,有些可以使用很长时间,有些却不行呢,这就涉及到一个后期维护的问题,后期维护室保存热镀锌钢格板使用期限的重要方面,所以热镀锌钢格板后期维护是非常重要的。

Every product has its service life. Why can some of the same products be used for a long time, while others are not? This involves a problem of late maintenance. Later maintenance room preserves the important aspect of the service life of hot-dip galvanized steel grilles, so late maintenance of hot-dip galvanized steel grilles is very important.

防止生白锈的措施:

Measures to prevent white rust are:

一、涂油

1. Oil coating

在镀锌钢格板上涂油,隔绝空气和锌。这种方式较简单,但是可以很好地起到防止生锈的作用,

Oil the galvanized steel sheet, isolate air and zinc. This method is relatively simple, but it can play a good role in preventing rust.

二、磷酸盐

Two, phosphate

镀锌钢格板表面涂漆会防锈,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形成疏松多孔结构,可以给油漆提供很好的立足点。

Galvanized steel sheets will be rustproof on the surface, 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

Chromic acid three, chromic acid

把镀锌钢格板浸入铬酸系溶液中,表面会形成活性低的薄膜,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。对防止白锈的产生很有效。

When the galvanized steel lattice is immersed in the chromic acid solution, a low activity film will be formed on the surface. Even if the film is damaged, the surrounding chromate will be dissolved in water and form a new film on the damaged part. It is effective for preventing white rust.

除了对镀锌钢格板作表面处理之外,也要注意日常的储存方式,比如储存的场所要防水防潮、通风良好、温差不大等。这样可以预防镀锌钢格板生白锈。

In addition to surface treatment of galvanized steel grilles, attention should also be paid to the daily storage methods, such as waterproof and moisture-proof storage places, good ventilation, little temperature difference, etc. This prevents the white rust of galvanized steel sheets.
