热镀锌高速公路护栏

热浸镀锌原理:镀锌铁要清洁干净,然后进行溶剂处理,干燥后浸入液态锌,锌铁锌层反应产生合金化,工艺为脱脂,洗涤,酸洗,有助于电镀 - 干燥 - 热镀锌,分离,冷却钝化。

热镀锌高速公路护栏的优点:
1.耐久性:在郊区,标准热浸镀锌防锈能力可保持50年以上,无需修理;在城市或近海地区,标准热浸镀锌涂层可以保存20年而不需要修理;

2.良好的可靠性:锌镀层和钢是冶金结合,这是钢表面的一部分,所以涂层的耐用性更加可靠。

3.涂层具有很强的韧性:锌涂层形成特殊的冶金结构,在运输和使用时可承受机械损伤。

4.全面保护:电镀的每一部分都可以镀锌,即使在凹陷处,尖角和隐藏处也可以得到充分的保护。

5.测试简单方便:热浸镀锌可视化,简单无损涂层测厚仪。
