9、温度：不低于5 ；钢构件表面温度：必须高于露点温度3 以上；The purpose of the environmental conditions test is to insure the quality of paint repair. The indicators of the test should include the following factors:Relative humility: 85%Ambient temperature: 5 Temperature of steel member surface:3 higher than dew-point temperatur
10、e.2.2.4 特别要求：在下列环境条件，涂装施工应停止进行。构件表面温度不高于环境空气露点温度30C，或者相对湿度大于85%；空气温度低于50C；当开始涂覆两个小时内有肯定的不良天气变化时；当因下雨、冷凝、霜冻等天气条件下，在构件表面形成潮气层时；当涂装施工环境光照有效发光流量低于500Lux时。23构件表面处理Member Surface Treatment 231构件表面处理主要是清理构件表面的污物，打磨修补部位。对于焊缝或油漆损坏较严重的部位，应用动力砂纸片和砂纸片打磨至钢构件金属表面，使该区域粗糙度达到St3级标准（非常彻底的手工和动力工具除锈）。Member surface tre
11、atment mainly includes removing of the dirt on the surface, grinding of repaired area to ST3 level (use sand paper to make sure there is certain roughness)。232对于龟裂的涂层，需将龟裂处涂层彻底打磨掉，并达到规定的粗糙度要求后再进行油漆的修补。233对于轻微损伤的涂层，不需打磨太深，只需进行适度打磨即可进行修补，修补可直接用Interthane 990面漆。For cracked and slightly scratched coats,
12、 do not grind too hard. Only grind to the base coat for repairing. Use finishing coat 990 to finish.234修补的区域不宜太小，要与原有涂层有3050的搭接，要求打磨成一定的坡度，以保证修补涂层与原涂层平缓过度；The repairing area should not be too small. There should have 3050mm adjoining area with the pre-existing coat. The grinding should have some gra

14、should follow the instruction. The quantity of diluents should be determined according to the temperature and coating conditions, yet no more than 5%.在Interseal 670 HS底漆涂装后，待其硬干后（Interseal 670 HS涂层在10C时完全干燥需要32小时以上）再进行Interseal 670 HS中间漆的涂装；Paint Intergrad 670 HS when the Intergrad 670 HS painting i
15、s dry (which needs 32 hours at 10C)Interseal 670 HS底漆涂层硬干后需用漆膜测厚仪进行测试，当漆膜厚度达到规定厚度后，需对上道漆层进行适当打磨，方可进行下道涂层的涂装施工。Commence coat painting when the coat of the previous procedure is dry and the thickness is acceptable (inspection instrument: paint film thickness gauge)不同温度条件下Intergrad 670 HS重涂间隔时间温度temp表干Touch Dry硬干Hard Dry自重涂间隔Re-coat by self最小Min.最大 Max.108小时hrs32小时hrs32小时hrs无Extended157小时hrs26小时hrs26小时hrs无Extended255小时hrs18小时hrs18小时hrs
