Fire Galvanized Water Tank

Common knowledge of galvanized steel plate water tank production process:
Galvanized steel plate water tank refers to coating a protective film on metal parts such as galvanized steel plate water tank. Galvanization has two purposes: 1) to increase conductivity and 2) to prevent oxidation and enhance corrosion resistance.
It is now widely used in the processing of building materials industry. The overall lifespan of the water tank has been extended, and the galvanized metal parts of the water tank can have a lifespan 3-5 years longer than the un galvanized metal parts in various environments.

In some commonly operated work processes in the industry, many masters can proficiently operate and produce high-quality craft products, but many galvanizing masters in the industry do not have a detailed understanding of some
galvanizing common knowledge words. Here are some common sense terms and definitions for everyone to understand:

1. Dispersion ability

It refers to the ability to evenly distribute deposited metal on the surface of cathode components under certain electrolysis conditions.
  2.Leveling ability

The ability of the plating solution to make the micro profile of the coating smoother than that of the substrate surface when forming a coating on a metal surface.

  3.Coverage capability

It is an important performance indicator of plating solution, which refers to the ability to fully cover the surface of the cathode part with deposited metal under certain electrolytic conditions, that is, the ability to deposit metal coating in
grooves or deep holes under specific conditions. It refers to the completeness of the distribution of the coating on the part.

  4.Current efficiency 

The ratio of the amount of electricity used to deposit metal to the total electricity is called the current efficiency of electroplating.

  5.Cathodic polarization degree

Cathodic polarization degree refers to the slope of the cathodic polarization curve, which is the degree to which the cathodic potential changes with the variation of cathodic current density.

  6.Pinholes or pockmarks

Hydrogen gas adheres to the cathode surface in the form of bubbles, preventing metal deposition in these areas. It can only deposit around the bubbles. If hydrogen bubbles remain on the cathode surface throughout the electroplating
process, the plated layer will have voids or through gaps; If hydrogen bubbles do not adhere firmly during the electroplating process and instead intermittently escape and adhere, these areas will form shallow pits or pits, commonly referred to as pinholes or pockmarks in the electroplating industry.

  7.Hydrogen embrittlement

After the reduction of hydrogen ions at the cathode, some form hydrogen gas and escape, while others infiltrate the base metal (especially high-strength metal materials) and coating in the form of atomic hydrogen, causing a decrease in the
toughness of the base metal and coating and becoming brittle. This phenomenon is called "hydrogen embrittlement".

At present, for some masters who have been working in the electroplating industry for several years or even decades, Dafeng's ability is sufficient to handle all the work in the industry. However, if we have to constantly Progress requires
continuous development and research of knowledge within the industry!
