  镀锌表面不能随便涂其他油漆,长时间会掉下来,但也不那么复杂,你涂黄漆是什么漆,建议先涂上一点试试。不,如果你照我说的做,你会100%的好:70微米的环氧防锈底漆,120微米的环氧铸铁中间漆,然后你可以在上面涂任何你喜欢的东西。

  The galvanized surface can't be painted with any other paint. It will fall down in a long time, but it's not so complicated. What kind of paint is yellow paint? It's suggested to try it first. No, if you do what I say, you will be 100% good: 70 micron epoxy antirust primer, 120 micron epoxy cast iron intermediate paint, and then you can apply anything you like on it.

  一般镀锌管不需要刷油漆,如玩油漆就刷银粉漆。钢管镀锌后,在其表面涂上一层锌层,将钢管与大气隔开,避免大气对钢管的直接接触和腐蚀,起到保护作用。对于钢管表面的锌涂层,由于锌的化学活性强,在室温下空气中会形成一层薄而致密的碳酸锌层,以保护锌不被氧化。因此,镀锌管,无论是锌管的表面还是钢管本身都有保护,不会生锈,不需要刷防锈漆。只有当镀锌层被损坏时(如钢管焊接、接头涂层烧坏),钢管暴露在空气中,失去了对镀锌层的保护,这时才需要刷防锈漆。

  Generally, the galvanized pipe does not need to be painted. If you play with the paint, you can brush the silver paint. After the steel pipe is galvanized, a layer of zinc shall be coated on its surface to separate the steel pipe from the atmosphere, so as to avoid the direct contact and corrosion of the atmosphere to the steel pipe and play a protective role. For the zinc coating on the steel pipe surface, due to the strong chemical activity of zinc, a thin and dense zinc carbonate layer will be formed in the air at room temperature to protect zinc from oxidation. Therefore, the galvanized pipe, no matter the surface of the zinc pipe or the steel pipe itself, is protected from rust and does not need to be painted with antirust paint. Only when the galvanized layer is damaged (such as steel pipe welding, joint coating burning out), the steel pipe is exposed to the air and loses the protection of the galvanized layer, then it is necessary to brush the antirust paint.

  适用于镀锌底漆(防锈底漆)有环氧锌黄底漆(双组份)、环氧酯锌黄底漆。镀锌件是有色金属,有色金属比黑色金属附着力差;红色常用的醇酸底漆、环氧铁红底漆不应该用于镀锌部件,否则很容易脱落。尤其需要指出的是:醇酸类油漆用在镀锌件,可以产生皂化反应,不仅涂层失效,原镀锌层也会受损。有条件时,可对磷化锌进行处理,或先薄喷一层磷化底漆。2. 或表面光滑的镀锌零件应进行扫砂处理。3.用溶剂擦拭镀锌工件表面和镀锌管表面。、环氧锌黄底漆稀释剂)去除工件的原油保护层,提高洁净度。4. 双组份环氧锌黄底漆:严格按照涂料与固化剂的比例调节涂料,固化30分钟后,调节适当的施工粘度,然后喷涂。单组份环氧酯锌黄底漆:施工粘度适宜,施工方法正确施工。

  Suitable for galvanized primer (antirust primer) with epoxy zinc yellow primer (two-component), epoxy ester zinc yellow primer. Galvanized parts are non-ferrous metals, and the adhesion of non-ferrous metals is worse than that of ferrous metals; the red common alkyd primer and epoxy iron red primer should not be used for galvanized parts, otherwise it is easy to fall off. In particular, it should be pointed out that alkyd paint used in galvanized parts can produce saponification reaction, not only coating failure, the original galvanized layer will also be damaged. When conditions permit, zinc phosphide can be treated or a thin layer of primer can be sprayed first. 2. Or the galvanized parts with smooth surface shall be sand swept. 3. Wipe the surface of galvanized workpiece and galvanized pipe with solvent. , epoxy zinc yellow primer diluent) remove the crude oil protective layer of the workpiece to improve the cleanliness. 4. Two component epoxy zinc yellow primer: adjust the coating in strict accordance with the ratio of coating and curing agent. After curing for 30 minutes, adjust the appropriate construction viscosity, and then spray. One component epoxy ester zinc yellow primer: the construction viscosity is appropriate, and the construction method is correct.
