1.热镀锌:锌层厚,耐腐蚀性强,价格高。

1. hot galvanizing: zinc layer thickness, corrosion resistance, high price.

热镀锌工艺:将铁件清洗干净,然后溶剂处理,烘干后浸入锌液中,铁与熔融锌反应生成一合金化的锌层,其流程为:脱脂--水洗--酸洗--助镀--烘干--热浸镀锌--分离--冷却钝化。

Hot-dip galvanizing process: the iron is cleaned, then the solvent is treated, dried and immersed in zinc solution. The iron reacts with molten zinc to form an alloyed zinc layer. The process is degreasing-washing-pickling-assisting plating-drying-hot dipping-galvanizing-separation-cooling passivation.

2.电镀锌:锌层薄,耐腐蚀性差,价格低。

2. zinc plating: thin zinc layer, poor corrosion resistance and low price.

电镀锌工艺:化学除油→热水洗→水洗→电解除油→热水洗→水洗→强腐蚀→水洗→电镀锌铁合金→水洗→水洗→出光→钝化→水洗→干燥。

Zinc plating process: chemical degreasing hot water washing water washing electrolytic relief oil hot water washing water washing strong corrosion water washing galvanized ferroalloy water washing light out passivation water washing drying.

热镀锌也称热浸锌,是将钢铁工件经过除油、除锈,呈现出无污、浸润的表面,立即浸入到预先将锌加热融熔了的镀槽中去,在工件表面形成一层锌镀层的方法。

Hot dip galvanizing, also known as hot dip galvanizing, is the method of forming a layer of zinc coating on the surface of the steel workpiece by degreasing, rusting, showing a clean, wet surface, immediately immersed into the galvanizing bath which melts the zinc in advance.

冷镀锌则是将同样经过了除油、除锈,呈现出无污、浸润的工件挂入专门的电镀槽里的阴极上,阳极用锌。接通直流电源,阳极上的锌离子向阴极迁移,并在阴极上放电,使工件镀上一层锌层的方法。

Cold galvanizing is the same after oil removal, rust removal, showing a pollution-free, soaking workpiece hanging on the cathode in a special electroplating bath, anode zinc. Turn on the DC power supply, the zinc ion on the anode migrates to the cathode, and discharges on the cathode, so that the workpiece is coated with a layer of zinc.

热镀锌的镀层较厚,一般为30-60微米,镀层防腐能力较高。适合于户外工作的钢铁制件,如高速公路围栏、电力铁塔、大尺寸紧固件等较为“粗糙”的工件的长期防锈。较早的铁质自来水管也是热镀锌的。

The hot-dip galvanized coating is thicker, generally 30-60 microns, and the coating has higher anticorrosion ability. Steel parts suitable for outdoor work, such as highway fences, power towers, large-size fasteners and other relatively rough parts of the long-term rust prevention. The earlier iron water pipes are also hot-dip galvanized.

电镀锌,工件表面光滑平整,但是因为镀层比较薄,一般在5-30微米以内,所以防腐蚀的时间会比较短。都用在室内使用制件的防锈。

Galvanized, the surface of the workpiece is smooth and smooth, but because the coating is thin, generally within 5-30 microns, so the time for corrosion protection will be shorter. They are used for rust prevention in indoor parts.
