罗庄铁艺栏杆在酸洗前应该做好哪些检查工作_双顿护栏

  • 来源: 发布时间:2019-05-15 1548 次浏览

酸洗前,检查和检查铁工件是否有镀锌的工艺孔在我们工厂(排气,锌条目,挂),腐蚀程度的工件表面的铁,和表面覆盖是否可以被盐酸(如油漆、油脂等应该被火,研磨,碱清洗,等等)。

    除油(碱洗)设备加温设备,清除铁块表面的油脂和油漆。洗去铁块表面的碱水及附件。用酸洗去除锈蚀、氧化皮等表面。 

    

酸洗后,检查和处理:酸洗效果是否理想,如酸洗不充分,再进行酸洗,如果处理前酸洗不彻底,需要酸洗后再退。清洗铁块表面的酸性水和其他附着物。

 

    上镀剂再次冲洗工件表面,确保电镀前表面没有生锈。干燥提高了铁片的温度,避免了铁片表面水分过多,在电镀时爆轰。热锌锌工件在440 -470 c的熔融锌溶液中浸泡,经过一定时间后,在铁艺工件表面形成一层锌铁合金层和纯锌涂层。

    钝化可使工件表面具有耐腐蚀性能,减少或延长白锈发生的时间。冷却防止工件淬火后产生集体组织开裂。涂层表面涂上锌结核和锌粉。

Before pickling, check and check whether there are galvanized process holes in iron workpieces in our factory (exhaust, zinc entry, hanging), whether the iron on the surface of the workpieces with corrosive degree, and whether the surface coverage can be hydrochloric acid (such as paint, grease, etc. should be fired, ground, alkali cleaned, etc.).

Degreasing (alkali washing) equipment heating equipment to remove grease and paint on the surface of iron block. Wash off the alkali water and accessories on the surface of the iron block. The surface of rust and oxide is removed by pickling.

After pickling, inspection and treatment: whether the pickling effect is ideal, such as inadequate pickling, then pickling, if the pickling before treatment is not complete, need pickling back. Clean acidic water and other attachments on the surface of iron blocks.

The surface of the workpiece is washed again with the plating agent to ensure that there is no rust on the surface before plating. Drying improves the temperature of iron sheet, avoids excessive moisture on the surface of iron sheet, and detonates during electroplating. Hot zinc and zinc workpieces were immersed in 440-470 C molten zinc solution. After a certain period of time, a zinc-iron alloy layer and a pure zinc coating were formed on the surface of iron workpieces.

Passivation can make the surface of the workpiece corrosion resistant and reduce or prolong the occurrence time of white rust. Cooling prevents collective structure cracking after quenching. Zinc nodules and zinc powder were coated on the surface of the coating.
