What are the more practical methods for stainless steel paint spraying?

       Stainless steel spraying is a common decorative material, but the oxidation resistance and corrosion resistance of stainless steel are not very high. We need to paint its surface to make it more durable. stainless

The spraying method of steel paint is different from that of ordinary paint. Let's take a look at how to spray stainless steel paint.

 

1. Chemical and Electrochemical Methods

 

This method is more complicated, but the effect is long-lasting. Chemical methods have a good effect on stainless steel spraying. We can perform surface treatments by chemical methods such as etching,

Coloring, electropolishing, etc. Etching is the use of screen printing techniques to cover parts that do not require etching and to etch various patterns. After tinting the stainless steel, dip it in

Cathodic hardening in a hot chromic acid or sulfuric acid solution followed by another acid solution. The base metal reacts with hot acid to form a transparent and colorless film, but it becomes obvious under the action of light.

display color. Electropolishing is the removal of very thin surface layers to give a shiny appearance. Electrolysis cannot remove surface defects such as scratches, burrs and oxidized colors. Through electrolysis,

The original flaws on the surface will become more apparent. The appearance quality before electropolishing plays a decisive role in the polishing effect.

2. Mechanical method

 

This is a reprocessing procedure. The surface of the stainless steel is processed, and then mechanically processed after processing, such as: turning, shot peening, grinding, polishing, buffing,

Brushed to form different surface finishes.

 

3. Embossing method

 

This approach has artistic effect. The embossing method can make the stainless steel look more beautiful. It uses the embossing and reticulation of the concave and convex geometric patterns by the engraved roller.

and corrugated surface processing (generally, the depth of single-sided embossing is 0.03mm, and the depth of double-sided embossing is 0.2mm).

Effect.

4. Coating method

 

This is the *simplest way. The processing methods of stainless steel exterior coating, etc., there are reprocessing after painting (pre-coating method), which should be used for roof building materials, and after processing.

Coating (post-coating method) must be used for building exterior building materials.

5. Spraying process

Let's look at the most basic spraying process. Usually, the stainless steel surface of the profile is glossy and not easy to paint, and even if it is used, it is easy to spend. need

Do the following processing. **First, to brush the stainless steel surface, use a wire brush or a sharpener to brush the surface. Second, to clean. Cleaners have special chemical products that can also be pickled.

If the quantity is not large, it can be cleaned by cleaning. Third, paint spraying, it is recommended to use spraying, because spraying paint, if the preparation is not thick, will flow phenomenon,

If you stir too thickly, the paint will peel off and spray unevenly. If sprayed, it's fine. Avoid such problems. Fourth, baking paint refers to placing the sprayed structure on the

in the cooking chamber and bake at a specific time. The temperature can't be too high, the time can't be too long, and it can't be too low or too early.
