Kishna Fibre-Plast & Fabrication

The PP Tank for Galvanizing Plant from Kishna Fiber Plast & Fabrication is specifically designed to withstand the rigorous demands of the galvanizing process. Built from high-quality polypropylene (PP), these tanks offer exceptional chemical resistance, durability, and longevity, making them an ideal choice for handling the harsh chemicals involved in galvanizing operations such as pickling, fluxing, and rinsing.

The galvanizing process is a method of coating steel or iron with a protective layer of zinc to prevent rusting and corrosion. The most common form of galvanizing is hot-dip galvanizing, though there are other methods like electro-galvanizing. Below is a step-by-step breakdown of the hot-dip galvanizing process, which is widely used in industrial applications:

1. Surface Preparation

Degreasing/Cleaning: The steel is first immersed in a degreasing or alkaline solution to remove organic contaminants like oil or grease. After cleaning, the steel is rinsed with water.

Pickling: The cleaned steel is dipped into an acidic solution (usually hydrochloric or sulfuric acid) to remove oxides, scale, or rust. The pickling tank (often a PP tank) is essential to this step, as it safely contains the corrosive acids used in this process.

Fluxing: To prevent oxidation of the steel before it’s dipped into molten zinc, it’s passed through a flux solution, usually made of zinc ammonium chloride. This ensures a strong bond between the steel and zinc coating.

2. Galvanizing (Zinc Bath)

Hot-Dip Process: The prepared steel is immersed in a bath of molten zinc, heated to around 450°C (840°F). During this step, the zinc reacts with the steel to form several layers of zinc-iron alloy that provide both adhesion and protection. The steel is kept in the zinc bath for a few minutes, ensuring a uniform coating.

Formation of Layers: As the steel is withdrawn from the zinc bath, the outermost layer of pure zinc solidifies and protects the underlying zinc-iron layers. These inner alloy layers form a metallurgical bond with the steel, making the coating durable and resistant to mechanical damage.
