illuminationLight (especially ultraviolet light) is one of the main causes of coating aging. Color coated plate is usually affected by light in the process of use. Therefore, light intensity and illumination time are important factors to be considered when analyzing environmental corrosivity.
The aging of coating will be accelerated if the temperature is too high, too low or too large temperature difference for a long time.
In the process of use, the color coated plate should avoid direct contact with acid, alkali, organic solvent, detergent, detergent and other chemicals, so as to avoid corrosion of the coating.
Industrial dust, suspended particles and other substances deposited on the coating surface for a long time can easily lead to coating aging.
In the humid and poor ventilation environment, the coating surface is easy to grow mold, which reduces the first overhaul life of color coated plate.
The surface of color coated plate will be abraded after being blown by wind, sand and mechanical friction.
Water and soil corrosion
Direct contact between the color coated plate and water and soil should be avoided as far as possible to reduce the corrosion caused by this.
A. 5.8 interaction with other materials
Sometimes the color coated plate may contact with or be used together with other materials. Due to the different properties of the materials, attention should be paid to whether there will be interaction between the materials.
In the actual use environment, there are many factors coexisting and influencing each other. At this time, we should find out the main influencing factors and determine the relationship between these factors as far as possible, so as to make a comprehensive and accurate judgment on the use environment.
