9、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 temperature. 特别要求：在下

10、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 treatment mainly i

11、ncludes 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, do not grind t

12、oo 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 gradient to insure

13、 the repaired coat connects well with the pre-existing coat.24油漆修补涂装Repairing Paint油漆修补需在白天或有充分照明的环境下进行。被修补涂层及基层的表面应干燥，无任何污染物（用干净的抹布充分擦净）。241 Interseal 670 HS油漆的涂装油漆A、B组份的调配必须依说明书进行。稀释剂的用量根据现场实际情况确定，通常不需要加稀释剂，只有当油漆太稠刷不开时才少量加入，应严格控制，最大用量不超过5%。严禁任意加入稀释剂。The blending of each paint group should follow t

14、he 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 is dry (which ne

15、eds 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

Only authorize person can enter the warehouse.44严格执行道康宁工地管理要求，在打磨工作开始前办理动火许可手续，油漆涂装前办理油漆涂装许可手续；Obey the regulations of site. Apply for fire permit before hot works. Apply for painting permit before work.45所有涂装人员必须配戴专用的口罩，以防油

28、漆中毒；All painters should wear special mask to prevent poisoning.46涂装部位做好防护措施（在地面补漆时用塑料布将地面铺垫好，所有的油漆用具都放置在专用的铁皮盘内），以免油漆对其他构件或环境造成污染。Painting area should have protecting measures to avoid pollution to other members and the environment (use plastic cloth when doing painting on the ground. All painting equipment should be placed in special trays).
