腐蚀老化对彩钢板的影响汇总
照明
彩涂板光（特别是紫外线）是造成涂层老化的主要原因之一。彩涂板在使用过程中通常会受到光线的影响。因此，光照强度和光照时间是分析环境腐蚀性时需要考虑的重要因素。
温度
温度过高、过低或长期温差过大都会加速涂层的老化。
化学的
彩涂板在使用过程中，应避免与酸、碱、有机溶剂、洗涤剂、洗涤剂等化学物质直接接触，以免涂层腐蚀。
沉积
工业粉尘、悬浮颗粒等物质长期沉积在涂层表面，容易导致涂层老化。
微生物
在潮湿、通风不良的环境中，涂层表面容易长霉，降低了彩涂板的首次大修寿命。
机械磨
彩涂板的表面在风、沙和机械摩擦的作用下会产生磨损。
水土流失
彩涂板应尽量避免与水、土直接接触，以减少由此引起的腐蚀。
A、 5.8与其他材料的相互作用
有时
彩涂板可能与其他材料接触或与其他材料一起使用。由于材料的性质不同，应注意材料之间是否存在相互作用。
在实际的使用环境中，有许多因素并存，相互影响。此时，应尽可能找出主要影响因素，确定这些因素之间的关系，从而对使用环境做出全面、准确的判断。
illumination
Light (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.
temperature
The aging of coating will be accelerated if the temperature is too high, too low or too large temperature difference for a long time.
chemical
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.
sediment
Industrial dust, suspended particles and other substances deposited on the coating surface for a long time can easily lead to coating aging.
microorganism
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.
Mechancal wear
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.
