What is degreasing and why it is important for galvanization?

The pretreatment section is an essential and fundamental element of the hot-dip galvanization process. In addition to pickling tanks, the pretreatment section also comprises degreasing, rinsing, fluxing, and acid stripping tanks. All operations related to the chemical preparations of the metal/ steel object that has to pass through the galvanization process are conducted in the degreasing pretreatment tank.

In this blog, our focus will remain on degreasing the pretreatment tank, and why this process is important to name a few.

Learning about degreasing

Galvanizers across the globe, including Ahmedabad, India are emphasizing this process as it’s an integral part of galvanization. Furthermore, the process of degreasing is also an integral element of the production process in numerous industries, including fabrication and assembling of metal parts (for example aircraft, appliances, automotive, electronics, and railroad). Degreasing is also called defatting or fat trimming.

Why degreasing is an important step

Without decreasing the process of galvanization will fail to achieve the targeted goals. For uniform coating of molten zinc, the iron/ steel object should be free from grease, oil, or any other foreign object. So, what is degreasing? For unawares, in simple language, degreasing is an exclusive process for removal of water-insoluble substances, these include:  

• Grease
• Fats
• Oils
• Waxes
• Carbon deposits
• Fluxes
• Tars

Material for degreasing

According to an industry expert, there are numerous types of degreasing material available in the market. These include:

• Degreasing sprays
• Powders
• Detergents
• Foams
• Vapor degreasing solvents
• Steam-delivered degreasers

Detergent based

Detergent-based products have been found brilliant for the process. It comprises a combination of chemical concentrates suspended in a liquid or powder base.

Solvent-based

In a solvent-based process, identified cleaning agent, including petroleum, chlorine, or alcohol-based solvent is applied directly to the surface to be degreased through spraying, brushing, or wiping. It depends on the process conductor. This process eliminates oil, dirt, loose particles, grease, and a host of other contaminants that are present on the surface of metal/ iron or a tank. Post degreasing, the tank or metal is ready for further process.

Vapour based degreasing

As far as vapour degreasing is concerned, solvents in the form of vapour are used and capitalized for the process. How does that happen? The solvents dissolve various contaminants present on the tank and steel/ iron made objects like auto parts and the dirt is removed by dripping off the part.

In addition, this process has been found useful to degrease tiny electronic parts, aircraft components, and automobile parts. What’s brilliant about this process is – it’s fast, reliable, and affordable. As a businessman, what else do you want!

If you are a novice in the field of hot-dip galvanization, it’s always good to take expert advice. 

Benefits of a quality-driven degreasing pretreatment tank

Over the years, the galvanization process and machines and tools related to the process have gone through drastic changes. Emerging technologies have further lifted the automation of the industry. Similar measures are pushing the growth of the industry. Traditional methods have become redundant now.

Here are a few key advantages and benefits of a sophisticated and comprehensive galvanization process:

• Chemical consistency
• Improvement in product quality
• The reduced workforce in the pretreatment area
• Compliance with environmental regulations
• Eco-friendly
• Complete capture of acid fumes
• Protection of the building structure
