What is the purpose of doing the Hull Tank Test when using alkaline galvanizing additives in a plating plant? Let's analyze it today.
(1) Judging the quality of chemical materials
In the case of shoddy products, plating factories must first determine whether the purchased chemical materials can be used through the Hull tank test, and how large the dosage should be.
(2) Determining the amount of additives to be added
A zincate solution to which only zinc oxide and sodium hydroxide are added produces a coating that is powdery, i.e., there are other precipitates in addition to metallic zinc.
Adding an appropriate amount of alkaline galvanizing additives to the plating solution turns it into all-metal zinc, and a fine crystalline and bright plating layer can be obtained. However, if too much is added, it will lead to more organic matter, serious inclusions in the plating layer, brittle plating, and blistering of the plating layer and other malfunctions.
Therefore, the maintenance and management of additives is very important. The first step is to choose Bigely alkaline galvanizing additives, the second is to strictly control the amount of additives, and the Hull bath test is almost an indispensable means of experimentation for the adjustment of various additives in the production solution. Of course, there are still many production details to pay attention to in the actual situation, such as the actual production volume, the tank capacity and the replenishment situation of different shifts should be taken into consideration, and then you can find Bigely engineers to provide technical support.
