英语翻译
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a coating of flux,which activates its surface to allow the zinc to wet it and react with it on immersion.When it is withdrawn surplus zinc drains back into bath.THe zinc coated article may be quenched by immersion in water(boshed) or simply cooled

答案

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...
