从涂料性能、环境条件、破坏特征等角度对涂层老化过程进行分析,根据服务寿命预测理论,运用数学方法,提出涂层耐久性预测的教学模型.并对2种建筑外墙涂层进行了试验研究.结果表明,该模型可以对建筑外墙涂层的服务年限进行较好的预测.
The coating aging process can be analyzed from coating performance, environmental conditions, and coating damage characteristics. Based on service life prediction theories and mathematical methods, a mathematical model of coating durability prediction was put forward. Two kinds of common construction exterior coatings were studied. The results indicated that the model can be used to better forecast the service life ofbuilding's exterior coating.
