大棚镀锌管的工艺与应用

硫酸盐镀锌大优点是电流效率高达100% ,沉积速率快,这是其他镀锌工艺无可比拟的。由于镀层结晶不够细致,分散能力与深镀能力较差,因而只适于几何形状简单的管材与线材等电镀。硫酸盐电镀锌铁合金工艺对传统的硫酸盐镀锌工艺进行优化,只保留了主盐硫酸锌,其余组分均舍弃。在组成新工艺配方中又加入适量铁盐,使原来的单金属镀层形成锌铁合金镀层。

The biggest advantage of sulphate zinc plating is that the current efficiency is as high as 100%, and the deposition rate is fast. This is unparalleled by other galvanizing processes. Due to the poor crystallization of the coating, poor dispersing power and deep plating ability, it is only suitable for electroplating of pipes and wires with simple geometry. The process of sulphate electroplating zinc alloy is optimized for the traditional sulfate zinc plating process. Only the main salt zinc sulfate is retained, and the remaining components are abandoned. A suitable amount of iron salt is added to the new process formulation to make the original single metal coating form zinc iron alloy coating.

热镀锌管用于水、污水、燃气、消防、空气、油、采暖蒸汽、大棚等低压流体输送和机械结构等使用。

Hot dip galvanized pipe is used for low pressure fluid conveying and mechanical structure for water, sewage, gas, fire fighting, air, oil, heating steam and greenhouse.

1、镀锌层的均匀性:钢管试样在硫酸铜溶液中连续浸渍五次不得变红。

1. Uniformity of galvanized coating: steel tube specimens are continuously impregnated in copper sulfate solution for five times and shall not turn red.

2、表面质量:济南镀锌管镀锌钢管的表面应有完整的镀锌层,不得有未镀上的黑斑和气泡存在,允许有不大的粗糙面和局部锌瘤存在。

2. Surface quality: the surface of galvanized steel tube in Ji'nan galvanized pipe should have a complete galvanized layer. No black spots and bubbles on the surface of the galvanized steel tube are not available, and there are not a lot of rough surface and local zinc tumor.

3、镀锌层重量:根据需方要求,镀锌钢管可作锌层重量测定,其平均值应不小于500g/平方米,其中任何试样不得小于480g/平方米。

3, galvanized layer weight: according to demand, galvanized steel pipe can be used as a zinc layer weight measurement, the average value should not less than 500g/ square meters, of which any sample must not be less than 480g/ square meters.
