海洋石油平台涂装工程涂料损耗分析 总被引:1,自引:0,他引:1
涂料的损耗控制一直都是涂装施工的重要环节,由于造成损耗的因素过多,设计方、施工方、涂料制造商都很难精确地计算损耗系数,很不利于施工管理和成本控制。海洋工程是个新兴的产业,施工中涂料的损耗常借鉴造船行业的经验,但由于二者在涂装工艺、结构、涂装设备等方面存在着很大的不同,导致损耗的差别很大。通过对国内石油行业多个海洋石油平台的涂装工程施工,积累了海洋工程涂料的使用数据,对影响涂料损耗的表面粗糙度、涂装方式、钢结构的几何形状、操作技术、环境因素、涂料浪费、修补等各项因素进行分析,尝试对涂料的损耗系数进行精确的统计。通过制定减少损耗的措施,在施工中严格控制,保证了新建海洋石油平台的涂料损耗系数控制在1.0~1.5之间,使涂料损耗达到了比较精准的控制。 相似文献

研究了制备PSt/PBA/PMMA LIPN涂料的新方法。采用种子乳液聚合技术制备了PSt/PBA/PMMA(聚苯乙烯/聚丙烯酸酯/聚甲基丙烯酸甲酯)乳胶型互穿网络聚合物涂料。结果表明当单体配比St:BA:MMA=4:3:2,交联剂用量为单体总量的1.5%,引发剂用量为1.2%,反应温度为70%左右时,涂料综合性能优良。说明采用乳液聚合技术合成的三元互穿乳液涂料较传统的丙烯酸酯类涂料性能优良,该涂料以水为溶剂,是一种典型的绿色涂料。 相似文献

Formability is one of the most important factors for pre-painted steel sheets (PCMs). Both high formability of the steel substrate and high integrity of the paint films on it after processing are required. In this study, elongation, tensile strength and elastic strain energy of various paint films were examined by tensile test, and the relationship between the mechanical properties of paint films and the integrity of paint films of PCM after bending and drawing were studied. We found that the required properties of paint films of PCM depended on the forming mode. In the bending mode, in which steel sheets were mainly subjected to tensile strain, the damage of paint films was dominated by the maximum strain and the tensile strength of the paint films. The paint films having higher maximum strain and higher tensile strength had better formability in bending. On the other hand, the damage of paint films was dominated by the maximum strain of paint films and elastic strain energy stored in paint films after deformation in the drawing mode in which steel sheets were subjected to tensile and compressive strain. The paint films having higher maximum strain and lower elastic strain energy had better formability in drawing. The relationship between the lubrication attributes of paint films and the limit of drawing ratio (LDR) of PCM was also studied. It was observed that the PCM with paint films having low friction coefficient had a higher LDR and it was the same ratio as the unpainted substrates. 相似文献
