Hot dip galvanizing plants  workflow

Everyone knows that hot dip galvanizing is actually a process of plating zinc on some metals, so that the quality of the metal is better. What is the workflow of this hot dip galvanizing plants ? Next we will understand in detail.

1, check

The main purpose of this inspection is the metal objects we want to hot-dip. How do we tell if their appearance has been corroded or whether it is covered by paint? If there are two situations mentioned above, we will Find a way to remove it.

2, alkaline washing

This step needs to be carried out together with heating. It is mainly for the metal surface to look like grease, and it has a good effect on its removal.

3, washing

As the name implies, the washing must also remove the alkali substance left in the alkaline washing in the previous step. It will further clean the remaining alkali to ensure that there is no residue at all.

4, pickling wash

For this step, it can be said that it is the same as the previous ones. Its purpose is nothing more than to remove the impurities on the metal surface and the residual liquid, to achieve perfect cleanliness. With these few items, the requirements for hot dip galvanizing equipment are very rigorous and very cumbersome and careful.

5, the upper plating agent heating

The next major step is that the plating aid ensures that the metal is prevented from oxidizing before galvanizing. The heating is mainly to ensure the drying of the metal surface and prevent moisture, which makes the subsequent operation more dangerous.

6, hot dip galvanizing

This step is the key to the whole process. It is to put the items to be plated into the already dissolved zinc solution, and then let it be put in the inside for a certain period of time and then plated.

Seeing the flow of hot dip galvanizing plants  so much, do you feel very cumbersome? But these steps are very necessary, only to ensure the quality of the final galvanizing equipment.
