水成膜消防泡沫对船舶甲板涂料颜色影响的研究

Research on Effect of Aqueous Film Forming Foam(AFFF) on Coatings Colors for Ship Deck

用数字显微镜对水成膜消防泡沫对环氧、聚氨酯甲板涂料的变色影响进行了研究。未经老化的环氧涂料涂膜致密,耐消防泡沫性能较好。老化10个月以上的环氧涂料,表面产生明显老化现象,耐消防泡沫性能大大下降,表面变白并产生细裂纹。

The effect of aqueous iflm forming foam on the discoloration of epoxy and polyurethane deck coatings was researched with the digital microscope. The iflm of the epoxy coatings was compact before aging and had preferable AFFF resistance. But after the epoxy coatings were aged for 10 months, aging phenomenon occurred obviously on the surfaces, the AFFF resistance declined signiifcantly and the surface was whitened and with ifne cracks.
