The anti‐permeability of an alkyd coating was modified by controlled airflow during the curing process. After the immersion test, the thinner airflow‐modified region had the best anti‐permeability compared with other thicker regions. The abnormal permeation behavior could be attributed to the difference in air pressure caused by the airflow. A model involving solvent evaporation and defect formation processes was proposed to interpret the airflow affected abnormal permeation behavior. This defect modification method may be employed to improve the corrosion resistance of an alkyd coating in a selected area and improve the painting quality in practice.

气流对醇酸树脂涂料的改性

通过在固化过程中控制气流来改变醇酸树脂涂料的抗渗透性。经过浸没测试，与其他较厚的区域相比，较薄的气流改性区域具有最佳的抗渗透性。异常的渗透行为可以归因于由气流引起的气压差。提出了一个涉及溶剂蒸发和缺陷形成过程的模型来解释气流影响的异常渗透行为。在实际中，可以使用这种缺陷改性方法来改善醇酸涂层在选定区域的耐腐蚀性并改善涂装质量。
