Although if you don't lose the paint, first of all, you have to make a good souvenir, first of all, you have to find a good master, so that you can do it well.

As the most reliable anti-corrosion process for iron products, galvanizing is widely used in various fields. For example, hot-dip galvanized products can be seen in power towers, traffic signs, communication towers, photovoltaic wind power supports, three-dimensional parking garage steel structures, plant steel structures, power station maintenance platforms, and even offshore oil extraction platforms. In the environment with harsh corrosive environment, hot-dip galvanized products will also corrode and rust.
In particular, some parts of the hot-dip galvanized layer are weaker and the parts with serious daily wear and tear are more likely to rust in advance.
When hot-dip galvanized structural parts rust, they need to be maintained to extend their service life. A common maintenance method is to use paint. If the following situations occur in the hot-dip galvanized components that have been painted, it means that there is a problem in the selection of paint, and the right paint is not selected!
Description: During the use of the hot-dip galvanized layer, the zinc reacts with the oxygen in the air to generate zinc oxide and zinc hydroxide, which adhere to the surface of the component to form a loose coating. At this time, if the general anticorrosive paint is painted, the problem of adhesion will occur in the paint film, and the phenomenon is peeling or bursting.
It is necessary to choose a special coating for hot-dip galvanizing maintenance, which can be directly brushed on the hot-dip galvanized surface, and can be integrated with the hot-dip galvanized layer, and there will be no problems of peeling and bursting paint. The high concentration of zinc powder in cold galvanizing with high zinc content adheres to the original galvanized layer and provides the same cathodic protection as hot-dip galvanizing, thus extending the service life of the component. And you can find a one-component product, which has the characteristics of simple construction and fast drying speed.
Not only does it greatly shorten the construction time, but it also reduces the impact on the surrounding residents.

This needs to look at the smoothness of the surface of the stainless steel; The smoother the surface, the easier it is to come off. Compared with ordinary steel plates, stainless steel plates are easy to fall off when painted.
Stainless steel plate painting method:
1.Whether it is a mirror or a brushed surface of stainless steel, its own adhesion is not strong, and it is best to use "baking paint" to make paint, and it is not easy to lose paint.
2.Hit it with electrochemical methods.
Stainless steel plate painting method:
Whether it is a mirror or a brushed surface of stainless steel, its own adhesion is not strong, and it is best to use "baking paint" to make paint, and it is not easy to lose paint.
Since this factory logo has been painted before, it is not necessary to apply a primer again if it is re-painted this time. As long as the factory mark is polished with sand coins, you can paint it directly. But since you are using spray paint, the polishing must be smooth and traceless, and the paint sprayed on the tour sample will be very shiny.
As for the original paint that has been applied to a few millimeters thick, it doesn't matter to you, it's not the thickness of the paint but the bottom layer of the batch, why is it 3 mm thick where it is thin, and 10 mm where it is thick.
That's because the 8-square-meter stainless steel plate is uneven, and the purpose is to keep the surface of this steel plate flat. You can spray it directly with glossy paint.

Remove rust first, if there is no rust, first use fine sandpaper to polish to increase paint adhesion, the primer can be used ordinary paint, or spray paint, the principle should be the same as the color that needs to be sprayed, or similar. Then it is sanded and then painted.
Galvanized sheet refers to a steel sheet with a layer of zinc on its surface. Galvanizing is a cost-effective and cost-effective method of corrosion protection that is often used, and about half of the world's zinc production is used in this process.
Galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life, and a layer of metal zinc is coated on the surface of the steel plate, and this galvanized steel plate is called galvanized plate.

Summary. The surface of the hot-dip galvanized steel sheet can be painted. However, it is necessary to spray a special primer first, and then a topcoat.
Galvanized surface painting can not only make the galvanized surface more solid and durable, but also improve the decorative effect of the galvanized surface, and can also extend its service life, and can also improve the anti-corrosion performance of the galvanized surface. In order to ensure the adhesion and protection effect of the paint, when spraying on the galvanized surface, the special primer should be sprayed first, and then the topcoat should be sprayed, so that the two layers of paint film can better protect the galvanized surface.
Can the surface of hot-dip galvanized steel be painted?
The surface of the hot-dip galvanized steel sheet can be painted. However, it is necessary to spray a special primer first, and then a topcoat. Galvanized surface painting can not only make the galvanized surface more solid and durable, but also improve the decorative effect of the galvanized surface, and can also extend its service life, and can also improve the anti-corrosion performance of the galvanized surface.
In order to ensure the adhesion and protection effect of the paint, when spraying on the galvanized surface, the special primer should be sprayed first, and then the topcoat should be sprayed, so that the two layers of paint film can better protect the galvanized surface.
What to pay attention to when painting on the galvanized surface 1. Before painting on the galvanized surface, the dirt, dust, and oil on the galvanized surface should be cleaned up with a matching solvent, and the galvanized surface should be polished flat with fine sandpaper, so that the adhesion between the paint and the galvanized surface is improved. 2. In the process of painting, a special primer should be sprayed first, and after the primer is sprayed, it needs to be polished again, and then the topcoat can be sprayed, and the colors of the two should be the same or similar as possible, so as to avoid the color difference of the paint film and the decorative effect of the galvanized surface. 3. Before painting, it is also necessary to mix the paint and thinner together according to the correct ratio, and it must be evenly blended.
In the process of painting, the thickness of the paint film must be kept within the specified range, not too thick or too thin, and there can be no omission or less coating.

Too professional, how can the market buy it?
You can definitely buy it, you can go to the hardware store and tell him.
Hahaha! Thank you, experts!!
A hundred thumbs up to you!
You are welcome! Have a great day!
In recent years, the production of galvanized sheet in China has increased year by year, and the import volume is also increasing year by year, and the growth rate is even higher than the increase in production; After deducting the double statistics of production, the consumption of galvanized sheet is about 5.27 million tons. After 1999, the import volume of galvanized sheet exceeded the production volume for the first time, and the self-sufficiency rate of domestic products was less than 50%, and there was a trend of decreasing year by year.

There is a clear difference.
Galvanized sheet, literally means that the heating zinc plating surface is divided into flowers and flowers, in fact, the crystals of zinc are not exposed, and the general surface of flowerless galvanizing is dark, and flowered galvanizing is divided into large, medium and small zinc flowers. >>>More
