The row skeleton manufacturer will tell you about the construction requirements and functions of metal surface spraying.

Rai skeleton manufacturer: construction requirements for metal surface spraying

Metal spraying is a widely used metal surface treatment measure because it is relatively more convenient and has good performance in terms of protective performance. The development of metal spraying technology is relatively mature so far, and there are application cases in many workshops. Whether in the practical value or aesthetic decorative effect, the cost of metal spraying is relatively high. However, metal spraying does not mean that construction must be carried out before construction. Specific requirements need to be met before construction. Let's take a look at the construction requirements:

In order to make the coating powder sprayed on the metal surface faster and more firmly attached to the surface of the metal workpiece, the surface of the metal workpiece itself should be very clean and smooth, and some oil stains, impurities and burrs on the surface should be treated in advance.

2. When spraying, the workpiece to be sprayed needs to be firmly in contact with the ground to ensure that there is no vibration around and the workpiece will not shake, which can ensure the spraying efficiency of the workpiece and the uniformity of metal spraying.

3. It is not enough to finish the spraying of the metal workpiece. There is still a lot of work to be done in the future, such as the need for a thermosetting process to make the metal spray coating more firmly attached to the surface of the workpiece, and then formally formed by drying and cooling.

4. After surface spraying, it is necessary to check the quality. For example, if the spraying is insufficient and there are loopholes, it is necessary to rework in time, because the effect of rework construction may be worse after a long time.

5. After the construction is over, pay attention to cleaning the site to ensure that the surrounding spray powder is cleaned up, and the powder in the air should be treated with special dust removal equipment to ensure air quality.

Ran skeleton manufacturer: what is the role of metal surface spraying?

(1) Some metal materials with surface defects can be effectively compensated by metal spraying. Phenolic resin is a widely used coating material, which can effectively cover the metal surface and close the oxide pores on the metal surface, which is very helpful to strengthen the quality of damaged metal products.

(2) metal surface spraying can also be used to resist the erosion of external chemical substances, common metal surface defects are corrosion and rust. Metal surface corrosion is a process that many metals will experience when exposed to the air, and corrosion is a violent chemical reaction with strong oxidation that occurs on the metal surface by strong acid and strong alkali. Both problems can be solved by spraying metal on the metal surface and attaching some chemically stable materials to the metal surface.

(3) In addition, metal surface spraying can also be used to improve the friction properties of metal surfaces. Some high-hardness materials as surface coatings can effectively improve the friction properties of metal workpieces and greatly extend their service life.
