jiangmen ceiling fan At first, as ventilation equipment for industrial factories and livestock farms, they did not care about appearance, so the appearance was fundamentally the silver nature of aluminum alloy. However, with the increasing commercialization of Jiangmen ceiling fans, many factories also pay more attention to the beauty of their products. Therefore, many manufacturers can customize Jiangmen ceiling fans in different colors.

The color of Jiangmen ceiling fans mainly relies on coating sprayed on the surface of the fan blades and frame. With the long-term use of electric fans, especially in many factories where there is heavy oil smoke and corrosive gases, the coating on the surface of the fan will show signs of aging, cracking, blackening, etc., which not only affects the appearance of the product, but also briefly shows the coating falling off during the operation of the fan. Therefore, after using the fan for a period of time, it is necessary to protect the external surface coating. There should be different protection plans for different damage conditions of coatings.

1. Coating loss of gloss, resulting in rough surface

The coating on the leaves of the Jiangmen ceiling fan has lost its luster and even become rough, indicating that the coating has begun to corrode. If left untreated, the erosion rate will accelerate. There is no need for repair work in the short term, but simple cleaning work can be carried out to tidy up the dust on the surface.

2. Cracks

(1) Micro cracks on the surface of the coating

When there are horizontal, vertical, or slight mesh cracks on the surface of the fan blade coating, it indicates that the surface coating has been damaged. Under normal circumstances, coating damage can become severe after about 6 months, even damaging the substrate of the blade. It is recommended to treat the areas where cracks occur within 6 months. The treatment method is as follows: ① Polish the coating to a depth until there are no cracks, and the width should be 5cm on either side of the straight direction of the cracks; ② Organize and clean the polishing area; ③ Strictly follow the instructions in the instruction manual to manufacture the topcoat, apply the coating to the primed area until it forms a lubricating surface with the surrounding coating.

(2) Deep cracks on the surface of the coating

At this point, horizontal or vertical cracks are clearly visible and have now reached the surface of the blade substrate. When there are deep cracks on the surface of the coating, it is recommended to treat it within 4 months. The treatment method is as follows: ① Polish the coating to a depth of about 3cm on both sides of the crack in the straight direction until it reaches the surface of the blade substrate; The entire polishing width is about 6cm in both directions; ② Organize and clean the polishing area; ③ Strictly follow the instructions to manufacture the primer, apply the primer to the polished substrate, and integrate it with the surrounding polished coating; ④ Strictly follow the instructions in the instruction manual to manufacture the topcoat, apply the coating to the primed area until it forms a lubricating surface with the surrounding coating.

3. Coating peeling or wear off

At this point, the coating on the fan blades has partially or completely fallen off, and the blade substrate is now exposed to the air. Generally, this situation occurs when the blades are corroded by corrosive gases in the environment. This situation is now quite severe, and it is necessary to treat the leaves in a timely manner, otherwise the leaves will be rapidly eroded and present a more serious problem. The processing method is as follows: ① Polish the residual old coating and the dirt on the blade substrate, and clean them up; ② Strictly follow the instructions to manufacture the primer, apply the primer to the polished substrate, and integrate it with the surrounding polished coating; ③ Strictly follow the instructions in the instruction manual to manufacture the topcoat, apply the coating to the primed area until it forms a lubricating surface with the surrounding coating.

The exterior of Jiangmen ceiling fans is mostly sprayed for beauty. Although the damage to the coating does not affect normal use, in some situations where the coating is damaged and needs to be planted, it indicates that the air itself is poor and slightly corroded. In this case, the coating will also have the effect of protecting the electric fan, so it is necessary to protect the coating in a timely manner.
