湿态附着力在防腐涂层性能检测中的应用
摘要:按标准规定,防腐涂层浸泡一定时间后,若未出现起泡、开裂、脱落等失效现象,评价结果为合格。但部分评价合格的涂层,其附着力已大幅下降,防腐性能大大降低。该文选取浸泡后评价合格的8种防腐涂层,对其干态附着力和酸性环境浸泡后的湿态附着力进行了对比测试。测试结果表明,浸泡后部分涂层的附着力已大幅降低或丧失,金属基体有明显腐蚀特征;部分涂层附着力有所降低;2种常温固化的防腐涂层附着力略有升高。可见,通过对比涂层干/湿附着力,或者跟踪涂层服役过程中附着力的变化,可量化掌握涂层性能的保持状况和发展趋势。
Abstract:According to the standard, after the anti-corrosion coating is immersed for a certain period of time, if there is no foaming, cracking, falling off, etc., the evaluation result is qualified. However, the adhesion and the corrosion resistance of some of the qualified coatings are greatly reduced. In this paper, eight kinds of anti-corrosion coatings qualified after soaking were selected, and the dry adhesion and wet adhesion after soaking in acidic environment were tested. The test results showed that the adhesion of some coatings after immersion was greatly reduced or lost, the metal matrix has obvious corrosion characteristics; the adhesion of some coatings was reduced; the adhesion of the two kinds of anti-corrosion coatings cured at room temperature was slightly increased. It can be seen that by comparing the dry/wet adhesion of the coating or tracking the change of adhesion during the coating service, the maintenance performance and development trend of the coating performance can be quantitatively grasped.
