Will the Stainless Steel Plate Lose Color?

Will stainless steel products rust after a long time?

It will be. Stainless steel will rust under certain conditions.

Stainless steel has the ability to resist atmospheric oxidation – that is, rust resistance.

At the same time, it also has the ability to corrode in the medium containing acid, alkali and salt – that is, corrosion resistance.

However, its corrosion resistance changes with the chemical composition of the steel itself, the state of interaction, the service conditions and the type of environmental medium.

For example, 304 steel pipe has absolutely excellent corrosion resistance in a dry and clean atmosphere, but if it is moved to the coastal area, it will soon rust in the sea fog containing a lot of salt;

The 316 steel pipe performs well.

Therefore, not any kind of stainless steel can resist corrosion and rust in any environment.

Stainless steel is a thin, firm, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent the continuous infiltration and oxidation of oxygen atoms, so as to obtain the ability of anti-corrosion.

Once the film is continuously damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate out, forming loose iron oxide, and the metal surface will be continuously corroded.

Will color stainless steel plate fade?

With the wide application of colored stainless steel plates, people who have stainless steel decorative plates will have such a question:

Will color stainless steel plate fade?

In fact, there are many processing technologies of color stainless steel plate.

Today, let’s talk about the four steps of color stainless steel plate processing and whether the color of color stainless steel plate will fade?

Will the Stainless Steel Plate Lose Color? 1

Four steps of processing color stainless steel plate

1. Degreasing activation

In the first step, degrease and activate the KTV stainless steel door with stainless steel degreasing activation solution, and then rinse with clean water.

2. Passivation treatment

After cleaning the door, passivate the door with stainless steel passivation paste or passivation solution for a period of time, from half an hour to more than two hours.

3. Alkaline water flushing

After passivation, rinse with alkaline water, clean and flush the door with water.

4. Spraying liquid

After completing the above steps, a stainless steel film is applied to the door to form a transparent hard film to prevent contamination such as fingerprints.

Will color stainless steel plate fade?

1. Generally, any colored stainless steel plate coated will not fade.

The so-called paint separation must be a transparent film. Yes, this is paint.

This is a transparent coating sprayed on the product to maintain the bright and beautiful appearance of the cup when leaving the factory. It was once called “varnish”.

2. Colored stainless steel plate is a colored stainless steel plate on the stainless steel substrate by surface coloring treatment technology.

Now the color of colored stainless steel plate is very beautiful. It is a very good decorative material.

The color stainless steel plate and color surface layer can withstand the temperature of 200 ° C, and the salt spray corrosion resistance is better than ordinary stainless steel, and the wear resistance and scratch resistance of colored stainless steel plate are equivalent to the performance of foil gold coating.

Under what circumstances will colored stainless steel fade?

1. Insufficient medium color plating time during processing

In order to save time and cost, some stainless steel processing plants will shorten the electroplating time.

Theoretically, the longer the plating time, the higher the hardness of the coating.

The longer the color on colored stainless steel lasts, the longer the service time.

The color will not fade after 5-10 years of use.

2. It is related to the application of stainless steel

We all know that stainless steel has a certain degree of acid-base imbalance.

For example, in the vicinity of coastal areas or during installation, some acid glue accidentally touches the surface of colored stainless steel.

If it is not treated in time or the treatment method is improper, it will cause varying degrees of damage to the surface color coating, and even lead to the rust of colored stainless steel on the steel substrate.

3. External human factors

The colored stainless steel surface will inevitably be damaged or faded due to improper use.

For example, scratches and corrosive liquids will fade colored stainless steel, and long-term use or long-term exposure to the sun and rain.

How to deal with stainless steel paint falling off?

Will the Stainless Steel Plate Lose Color? 2

In order to make stainless steel look better, some friends will spray paint on its surface, and the paint is easy to fall off when the paint is long.

So how to deal with the paint fall off of stainless steel? Let’s study together.

1. How to deal with stainless steel paint falling off?

Firstly, clean all the residual paint film at the paint falling position to keep the stainless steel surface clean and bright.

Secondly, wipe the stainless steel surface with solvent to clean the oil, dust and dirt on the surface, and then apply a layer of epoxy primer on the stainless steel surface.

When the paint film is dry, spray fluorocarbon paint on the stainless steel surface.

2. How to clean and maintain stainless steel products?

1. If the air is relatively humid, after a long time, there will be a lot of dust and oil on the surface of stainless steel products, and it is also easy to cause electrochemical reaction, resulting in accelerated corrosion of products.

To this end, it is recommended that you should regularly wipe the stainless steel surface with detergent, dry it with a dry rag, and keep it dry and cool all the time.

2. In order to effectively prolong the service life of stainless steel products, after cleaning the stainless steel surface, waxing treatment should also be carried out on the surface, that is, a layer of antirust material needs to be painted on the surface.

However, the antirust effect of this material is generally not long and can only be guaranteed for about three months, but the price is not expensive and the amount used each time is not much.

3. Although the corrosion resistance of stainless steel is relatively high, rust will still appear after a long time.

In order to effectively prevent stainless steel from rusting, a layer of antirust layer should also be added to the surface of stainless steel, that is, electroplating process should be adopted on the surface to add a layer of electroplated coating on the surface.
