8、ificates and meets the requirement of the drawings (first andsecond repair paint is 670, third repair paint is 990).2222 检查补漆所用工具是否齐全,现场补漆均为刷涂,至少要备足以下油漆补漆工具:1)砂轮机;2)钢丝刷(要求很细的钢丝刷) ;3)普通粗砂纸;4)油漆毛刷,毛刷必须为羊毛刷,且不能掉毛(应备几种规格) ;5)干净的抹布。Repair paint at site is brush work. The tool for brush must be goat hair

9、brushthat does not loss hair.2223 检查湿度计、温度计、漆膜测厚仪、带该度的玻璃量杯等各种配套仪表、器具是否齐全。Make sure hygrometer, thermometer, paint film thickness gauge and otherapparatus are ready.223 环境条件的检测 Environmental Conditions Test检测环境条件的目的是为了确保油漆修补的质量, 主要包括相对湿度、 温度、 露点温度。其各项指标条件如下:相对温度:对于 Interseal 670 HS不大于 85%,对于 Intertha

10、ne 990 不大于 80%。环境温度:不低于 5 ;4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 ofpaint 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 de

11、w-point temperature.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3 C,或者相对湿度大于85%;空气温度低于 5 C;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 Treatment231 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

12、除锈) 。Member surface treatment mainly includes removing of the dirt on the surface,grinding of repaired area to ST3 level (use sand paper to make sure there is certainroughness)。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

13、slightly scratched coats, do not grind too hard. Only grind tothe 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 adjoiningarea with the pre-existing coat. The grin

14、ding should have some gradient to insure500the 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。T

15、he blending of each paint group should follow the instruction. The quantityof 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

16、when the Intergrad 670 HS painting is dry (which needs32 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 thecoat of the previous procedure is dry and thethickness is acceptable (inspection instrument: paint film thickness gauge)不同温
