你了解什么是热镀锌管吗?

热镀锌管是使熔融金属与铁基体反应而产生合金层,从而使基体和镀层二者相结合。热镀锌是先将钢管进行酸洗,为了去除钢管表面的氧化铁,酸洗后,通过氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗,然后送入热浸镀槽中。

The hot-dip galvanizing tube is to make the molten metal react with the iron matrix to produce the alloy layer, so that the matrix and the two layers of the coating are combined. Hot dip galvanizing is to pickle steel pipes first, then remove iron oxides on the surface of steel pipes, then pickle them, then clean them through ammonium chloride or zinc chloride water solution or ammonium chloride and zinc chloride mixed water solution tank, then send them into hot dip bath.

热镀锌管具有镀层均匀,附着力强,使用寿命长等优点。钢管基体与熔融的镀液发生复杂的物理、化学反应,形成耐腐蚀的结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。

The hot-dip galvanized pipe has the advantages of uniform coating, strong adhesion, long service life and so on. The complex physical and chemical reactions occurred between the steel tube matrix and the molten plating bath to form a corrosion-resistant and tightly structured zinc - iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.

1、镀锌层的均匀性:钢管试样在硫酸铜溶液中连续浸渍5次不得变红。

1, the uniformity of the galvanized layer: the steel tube specimen is impregnated continuously for 5 times in the copper sulfate solution and must not be reddened.

2、表面质量: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, the surface quality: the surface of galvanized steel pipe should have a complete zinc coating. There must be no black spots and bubbles on the surface, allowing for little rough surface and localized 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, zinc coating weight: according to the requirements of the buyer, the galvanized steel pipe can be used for the determination of the zinc layer weight, the average value should not be less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
