What factors will affect the quality of color steel plates

Color steel plates are commonly used in non-ferrous metal smelters in the metallurgical and power industries (such as copper, zinc, aluminum, lead, etc.) and have relatively high corrosion resistance. So what factors will cause the quality of color steel plates? Let's take a look together.
1. Temperature
The coating softens at high temperatures and is prone to corroding the medium, penetrating the substrate, increasing the oxygen content in the water at high temperatures, and increasing the corrosion rate at certain temperatures.
2. The substrate corrosion caused by moisture cutting and processing damage is electrochemical corrosion, which is not easy to form corrosive batteries (i.e. electrochemical circuits) under low humidity.
If the temperature difference between day and night is large, condensation is likely to occur and electrochemical corrosion may occur on the bare metal. In addition, if the temperature difference is large, the cold and high temperature deformation of the coating will often occur, thereby accelerating aging and relaxation. Coatings and external corrosive media can easily penetrate the substrate.
4. The time and intensity of sunlight is an electromagnetic wave, divided into γ X-rays, ultraviolet rays, visible light, infrared rays, microwaves, and radio waves. Waves and radio waves have low energy and do not interact with matter. Infrared also has a low energy spectrum, which allows the chemical bonds of substances to be stretched and bent, but not broken. Visible light provides rich colors for all things.
5. Precipitation and acidity of precipitation The acidity of rainstorm is undoubtedly not conducive to corrosion resistance. However, this has a dual impact on rainfall. For steep wall and roof panels, the function of sedimentation is to clean the surface of the steel plate and wash away corrosion products on the surface. Corrosion is more likely to occur during heavy rainfall.
6. Wind direction and speed Wind direction and speed are similar to water and often interrelated. This is a test of material connections, as wind can loosen the connections and allow rainwater to seep into the interior.
7. Corrosive deposits such as chloride ions and sulfur dioxide have a promoting effect on corrosion. These sediments mainly occur on beaches and in areas with severe industrial pollution (power plants, smelters, etc.).
