The weather resistance of powder coating fluorocarbon spraying mesh plate first comes from the unique chemical stability of fluorocarbon coating. The molecular structure of this coating contains stable chemical bonds, which can resist long-term exposure to ultraviolet rays in the sun. Outdoor ultraviolet rays will gradually age and crack ordinary coatings, while fluorocarbon coatings will not undergo obvious chemical decomposition under the action of ultraviolet rays, and the molecular structure remains stable. This prevents the coating on the surface of powder coating fluorocarbon spraying mesh plate from powdering or peeling due to long-term exposure to sunlight, and fundamentally resists the erosion of ultraviolet rays on powder coating fluorocarbon spraying mesh plate.
Faced with frequent temperature changes outdoors, the coating and substrate of powder coating fluorocarbon spraying mesh plate show good synergistic adaptability. Whether it is high temperature exposure in summer or low temperature and severe cold in winter, the thermal expansion and contraction coefficient of fluorocarbon coating is close to that of powder coating fluorocarbon spraying mesh plate substrate, and will not produce excessive internal stress due to drastic temperature fluctuations. This matching avoids cracks in the coating due to repeated expansion and contraction, ensuring that the coating can still adhere closely to the surface of the powder coating fluorocarbon spraying mesh plate in extreme temperature difference environments, forming a continuous protective barrier to prevent moisture and impurities from penetrating into the interior of the substrate through gaps.
The low surface energy of the fluorocarbon coating plays a key role in dealing with humid environments such as rain and snow. This characteristic makes the coating surface difficult to be wetted by water. Rainwater falling on the powder coating fluorocarbon spraying mesh plate will form water droplets and slide down quickly, making it difficult to penetrate under the coating. Even in the high-humidity rainy season or foggy weather, it is not easy for water vapor to condense on the coating surface, reducing the risk of substrate corrosion caused by long-term adhesion of moisture. At the same time, the dense structure of the coating also prevents moisture from penetrating through capillary action, allowing the powder coating fluorocarbon spraying mesh plate to always remain dry in a humid environment and maintain structural stability.
Fluorocarbon coatings have strong resistance to pollutants in the air, such as industrial dust, acid and alkali mist, etc. After contacting these pollutants, ordinary coatings are prone to chemical reactions and discoloration and corrosion, while the chemical inertness of fluorocarbon coatings makes it difficult to react with these substances. When industrial dust falls on the surface of powder coating fluorocarbon spraying mesh plate, it will not combine with the coating and can be easily washed away by rain; acid and alkali mists are also difficult to erode the molecular structure of the coating, and will not cause spots or damage on the surface of the coating, ensuring that the powder coating fluorocarbon spraying mesh plate can still maintain stable appearance and performance in outdoor environments with severe pollution.
In strong winds, the structural design of powder coating fluorocarbon spraying mesh plate and the wear resistance of the coating jointly cope with the impact of wind and sand. Strong winds outdoors are often mixed with sand particles, which constantly hit the surface of objects, and ordinary coatings are easily scratched and lose their protective effect. The composite process of powder spraying and fluorocarbon spraying allows the coating to form a certain hardness and toughness. The impact of sand particles will only cause slight friction on the surface and will not easily scratch the coating. At the same time, the mesh structure of the powder coating fluorocarbon spraying mesh plate disperses the wind force, reduces the continuous impact of wind and sand on the local area, and further reduces the possibility of wear.
When dealing with seasonal extreme weather, such as heavy rain and hail, the weather resistance of the powder coating fluorocarbon spraying mesh plate is reflected in the impact resistance of the overall structure. The strong water flow impact brought by heavy rain will not break the combination of the coating and the substrate; although the impact of hail may produce local pressure, the toughness of the fluorocarbon coating can absorb part of the impact force and prevent the coating from breaking. The frame and connection parts of the powder coating fluorocarbon spraying mesh plate will not rust or loosen in these extreme weathers due to the protection of the coating, ensuring that the entire powder coating fluorocarbon spraying mesh plate can still maintain complete protection functions after experiencing bad weather.
After long-term exposure to outdoor environments, the weather resistance of the powder coating fluorocarbon spraying mesh plate is also reflected in the long-term stability of the appearance. After several years of exposure to wind and sun, the surface of ordinary powder coating fluorocarbon spraying mesh plate will become gray and lose its luster, while fluorocarbon coating has good gloss retention and color retention. Even after years of outdoor use, the surface of powder coating fluorocarbon spraying mesh plate can still maintain its original color and gloss, and will not show obvious discoloration or fading due to climate erosion. This stability of appearance not only allows powder coating fluorocarbon spraying mesh plate to maintain its beauty for a long time, but also indirectly reflects the stability of its internal performance, proving that the coating is still effectively playing a protective role and resisting the continuous erosion of various complex outdoor climates.
