1.2编制说明Description本防腐油漆涂装施工方案是针对道康宁(张家港)有限公司19万吨/年有机硅聚硅氧烷项目(二期)工程钢结构工程而编制的。
This construction scheme is compiled for Dow Corning 190kt/a Siloxane Project in Zhangjiagang (Phase 2)1.3适用范围Applicable Scope本方案仅适用于(二期)工程Team A区PartA&C区钢结构工程的现场油漆修补工作。
This construction scheme is applicable only for site paint repair work in steel structure installation in Team A of Phase二、油漆修补工艺Paint Repair Work Techniques2.1工艺流程图Process Flow Diagram (PFD)2.2修补工艺Repair Work Techniques2.2.1确定修补范围Confirm the Regions that Needs Repair检查构件外观,对所有在运输、倒运、现场焊接接等过程中破坏的涂层用记号笔作好标记,并标记出打磨处理的范围。
Check the appearance of members. Mark all the damaged coats caused during transportation and welding by marking pen. Highlight the area that needs grinding. 2.2.2油漆、工具进场验收 Inspection and Acceptance of Paint and Tools2.2.2.1钢结构防腐油漆、稀释剂和固化剂的品种、规格、性能应与要求相符,检查油漆产品的质量合格证明文件、中文标志及检验报告;本工程钢结构油漆修补采用如下的油漆系统。
Inspect the category, type of paint as per drawings. Make sure the paint has all the quality certificates and meets the requirement of the drawings (first and second repair paint is 670, third repair paint is 990).2.2.2.2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 brush that does not loss hair.2.2.2.3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 other apparatus are ready.2.2.3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Interthane 990不大于80%。
环境温度: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 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。
2.3构件表面处理Member Surface Treatment2.3.1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 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)。
2.3.2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。
2.3.3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 too hard. Only grind to the base coat for repairing. Use finishing coat 990 to finish.2.3.4修补的区域不宜太小,要与原有涂层有30~50㎜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 30~50mm adjoining area with the pre-existing coat. The grinding should have some gradient to insurethe repaired coat connects well with the pre-existing coat.2.4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)。
2.4.1 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 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10°C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 needs 32 hours at 10°C)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重涂间隔时间底漆和中间漆的漆膜厚度如达不到,应按规定的程序再次进行Intergrad 670 HS油漆的涂刷。
