Question

请帮忙翻译一下谢谢

Hot dip galvanizing is a process by which iron and steel can be treated to prevent rusting. In essence it involves dipping the article with a chemically clean surface into a bath of molten zinc which reacts with the iron and forms a coating. The principles have remained unchanged since galvanizing first became a trade more than 150 years ago, but a vast amount of research on all aspects of the process has enabled galvanizing today to be a techincally advanced industry.

Since molten zinc cannot react with iron or steel covered with mill scale or oil, the article to be galvanized must first be prepared for hot dipping by cleaning processes which may include degreasing, grit blasting and acid cleaning(pickling), The article next receives a coating of flux, which activates its surface to allow the zinc to wet it and react with it on immersion. When it is withdrawn surplus zinc drains back into bath. THe zinc coated article may be quenched by immersion in water(boshed) or simply cooled in air.

The two main processes used differ in the method by which the flux coating is applied. In the wet process the work after pickling and rinsing is dipped through a flux layer floating on the surface of the zinc bath. In the more common, dry galvanizing process a layer of flux is dried onto the work before dipping and the work immersed in a clear bath of molten zinc.

热浸镀锌是其中铁和钢可以治疗，以防止生锈的过程。从本质上讲它涉及到一个熔融浸渍锌浴它与铁反应，形成一个涂层用化学清洁表面文章。这些原则仍然不变，因为镀锌首次成为超过150年前一个行业，而是一个研究这一进程的各个方面，使大量镀锌今天是techincally先进的产业。

由于锌液不能反应铸铁或磨规模或油的钢，文章被清洗过程，可能包括除油，喷砂和酸洗（酸洗）镀锌必须先热浸准备，文章下篇收到涂布助焊剂，激活其表面，使锌湿它，用它作出反应浸泡。当它被撤回盈余锌水渠回澡。锌涂层的文章，可在淬火只是在空气冷却水（boshed）或浸泡。

使用的两个主要过程不同，所依据的助焊剂涂层的应用方法。在湿法工艺酸洗和冲洗后的工作是透过通量下降对锌浴表面浮层。在较常见，干热镀锌过程中的通量层之前把工作干到浸渍，并在熔化的锌浴清除工作。

热浸镀锌是一个过程,钢和铁可以治疗,以免生锈。本质上,这包括浸渍文章以化学清洗表面成浴液与铁锌的反应,形成一层。不变的原则,热浸镀锌第一次成为贸易超过150年前,但是大量的研究方面的过程使得镀锌今天有techincally先进的工业。

自从铸造锌不能与铁或钢长满了轧机油,或者是镀锌必须先准备清洗过程热浸以可包括脱脂、砂砾爆破、酸洗(酸洗),这篇文章下收到一层焊剂,激活其表面允许锌对湿它和反应与特色。当它被撤回剩余锌消耗回浴。锌涂层可以淬火沉浸在水里(boshed)或仅仅是在空气中冷却。

这两个主要的过程中使用的方法,采用不同的流量涂层。在湿式处理后的工作是通过冲洗、浸泡酸洗了磁层浮在水面上的锌浴。在干燥过程中越来越普遍,热浸镀锌层焊剂干到工作和工作之前浸渍沉浸在清水洗熔化的锌。
