济南镀锌管做防腐需要注意什么?

我们普通钢材产品跟镀锌钢材产品的不同处之一就是,普通产品容易被腐蚀生锈。而镀锌产品在经过镀锌处理之后,能够有效的起到防腐蚀的作用。但不能保证多年以后不生锈,镀锌防锈只是短时间,所以必须刷漆保证十几年后也不生锈。

One of the differences between our ordinary steel products and galvanized steel products is that ordinary products are easy to be corroded and rusted. And galvanized products after galvanizing treatment, can effectively play a role in corrosion prevention. However, it can not guarantee that it will not rust after many years, and the galvanized rust prevention is only a short time, so it must be painted to ensure that it will not rust after more than ten years.

但是镀锌板和镀锌钢管防腐漆底材与钢铁材质有很大的差别,镀锌板过于光滑,一般油漆很难附着在表面,即使干燥后也很容易脱落,无法达到防腐的作用。所以对于油漆的选择一般是底漆配套面漆,底漆选用具有强附着力的双组分环氧锌黄底漆或者环氧富锌底漆,面漆使用硬度较高的丙烯酸聚氨酯面漆或者氟碳面漆。镀锌管防腐漆施工方法如下:

However, there is a big difference between galvanized sheet and galvanized steel pipe anticorrosive paint substrate and steel material, galvanized sheet is too smooth, general paint is difficult to adhere to the surface, even after drying, it is easy to fall off, unable to achieve the anti-corrosion effect. Therefore, the selection of the paint is generally the primer matching the top coat, the primer selects the two-component epoxy zinc yellow primer or epoxy zinc rich primer with strong adhesion, and the high hardness acrylic polyurethane topcoat or fluorocarbon finish is used for the top coat. The construction method of anticorrosive paint for galvanized pipe is as follows:

首先是 底材处理:镀锌板表面非常光滑,也要采用打磨处理,使表面具有一定的粗糙度更有利于油漆粘附。

First of all, substrate treatment: galvanized sheet surface is very smooth, but also to use grinding treatment, so that the surface has a certain roughness, more conducive to paint adhesion.

其次是 底漆涂装:环氧锌黄底漆的甲乙组分按照5:1的比例混合,添加适量环氧稀释剂,充分搅拌均匀,喷涂2遍,每遍间隔6小时以上,实干24小时。

Secondly, primer coating: the A and B components of the epoxy zinc yellow primer are mixed according to the proportion of 5:1, proper amount of epoxy diluent is added, and the mixture is fully stirred and sprayed twice. The interval between each time is more than 6 hours, and the dry time is 24 hours.

然后还有面漆涂装:丙烯酸聚氨酯面漆甲乙组分按照5:1的比例混合,添加丙烯酸稀释剂,充分搅拌均匀,喷涂2遍,每遍间隔6小时以上,实干24小时。

Then there is top coat coating: A and B components of acrylic polyurethane top coat are mixed in the proportion of 5:1, acrylic diluent is added, fully stirred and sprayed twice, with an interval of more than 6 hours and dry for 24 hours.

再然后就是施工验收:施工完毕,漆膜光滑平整,颜色均匀。此时油漆中仍有残余的溶剂尚未挥发,需要7天左右时间才能彻底干燥,达到理想的效果。

Then there is the construction acceptance: after the construction, the paint film is smooth and flat, and the color is even. At this time, there is still residual solvent in the paint which has not yet volatilized, and it takes about 7 days to dry thoroughly to achieve the desired effect.
