2)曲面角检测8r 或更多用凹角:5r 或更多用凸角钢结构检测清理准备工作喷砂清理表面处理检查涂底漆鳞片衬里(第一次涂)鳞片衬里(第二次涂)涂层的表面处理半成品检查修理1)喷砂等级:ISOSa21 2检查涂抹工具修理修 理1)喷砂后8 小时内完成1)涂底漆后30 天内 2) 危 害 性 气 体 成 分 : 最 大 50ppm(苯乙烯)1)在第一次和第二次检查时 实施外观检查,检测遗漏的区域,过度集灰和裂痕 2)仅在第二次检测时用电火 花检测仪检测针孔3)涂层厚度检测(两次均需 检测)4)木锤振打实验(仅在第二 次检测)Environment condition: Ambient temperature: 5℃ or higher, unless otherwise specified. Surface temperature: over 3℃ more than dew-point temperature, humidity less than 85% or less Environment condition would influence sandblasting, primer and lining.1)Visual inspection: Inspect blister and notch (defectives if 0.5mm or more) on the surface and welding area, deformation of structure outer end. 2)Camber angle inspection Concave angle for 8r or more, convex angle for 5r or more Steel structure detectionCleaning Preparation Sandblasting Cleaning Surface treatment Priming Flake lining (first) Flake lining (Second) Coating surface treatment Semi-finished Top coat Final inspection Repair 1)Sandblasting grade :ISOSa21 2Inspect dauber Repair Repair Protecting lining 1) Completed within 8h upon sandblasting 1)Within 30d upon priming 2) Hazardous gas: maximum 50ppm (styrene) 1)Visual inspection to be executed between the first inspection and the second inspection, inspecting omitted area, much dust and crack 2) Pinhole inspected by electronic spark tester in the second inspection 3)Coating thickness inspection (done during two inspections) 4 ) Vibrating accelerant of 0.15-0.2%, defined amount of color paste. The construction material shall be prepared by portable agitator according to the sequence of lining material, accelerant, mixing, initiator and mixing. 2.4.4施工方法(涂抹磙压法)Construction method (applying and rolling) 2.4.4.1 主要用于胶泥状鳞片衬里涂抹施工。
Mainly used for the daub and construction of the mortar flake lining. 2.4.4.2 抹涂磙压施工作业是通过作业人员用抹子、灰刀等工具按一定厚度要求同一涂抹方向涂抹到被防护的表面,再经过压磙磙压、除泡压实、压平、使鳞片按规定方向叠压排列后固化成型The construction operation of brush coating and rolling is operated by operating personnel by trowel, putty knife and other tools according a certain required thickness and in the same direction to paint on the protected surface, and by roller rolling, blocking, compaction and smashing process, to make the flakes cured and molded after laminating arrangement in the required direction. 2.4.5 施工特点: Construction features: 2.4.5.1 内 衬 施工 以手 工 作 业为 主。
Lining construction is based on manual operation. 2.4.5.2 衬里层必须完全封闭 Lining layer must be completely closed. 2.4.5.3 衬里材料配制时须配备专用的搅拌混料设备Lining materials preparation should be equipped with special mixing equipment. 2.4.5.4 衬里施工环境差,属易燃有害作业,故安全防护十分重要Lining construction environment is bad, belonging to flammable harmful operation, thus the safety protection is very important. 2.4.6 工料固化时间的控制The curing time control of the construction material. 2.4.6.1 工料固化时间即工料配制后的有效使用时间,主要控制点为:The construction material curing time refers to the effective using time after the making-up of the construction material. a.固化剂用量 (为胶泥量的 2-3%) ;促进剂用量(为胶泥量的0.2-0.3%)The curing agent dosage (2-3% of the daub); promoting agent (0.2-0.3% of the daub) b.一次配料量; Batch; c.施工人员作业能力; Work ability of the operation personnel; d.施工现场条件(温度、湿度、施工距离等);Construction site conditions (temperature, humidity, distance, etc.); e.作业界面的施工难易程度; The construction difficulty of the operational interface; 2.4.6.2 通过固化时间的控制,避免材料的浪费、人员窝工,防腐层固化时间过早或固化不足,以降低成本、提高工效、保证施工质量。
By the control of the curing time can avoid material waste, sabotage work, the cure time of the anticorrosive coating earlier or under cure, to reduce cost, improve work efficiency and ensure the construction quality. 2.4.7 界面生成气泡的控制Control the formation of air bubbles of the Interface 2.4.7.1 配料过程的气泡用专用搅拌设备进行搅拌配料解决(本公司提供的材料已抽除大部分真空,现场不用真空搅拌) Adopt the specific mixing equipment to stir the ingredients in the process of dosing (the materials provided by our company have been pumped the most vacuum, no vacuum stirring on site). 2.4.7.2 施工作业时,严禁随意搅动工料。
托料、上抹刀、涂抹应依次进行,尽力减少无意翻动 In the construction process, casual stirring is strictly prohibited. Material holding, using spatula, plastering should be carried out in turn, and try to diminish accidentally flipping. 2.4.7.3 涂抹时、抹刀与被抹面保持一定的角度,使胶料沿被防护表面之间涂敷,达到使界面空气在涂抹中不断从界面间推挤出,严禁将料推挤在中间,然后向四周摊开式滩涂,以抑制气泡产生Keep the spatula and the painted surface in a certain angle during plastering, to make the mortar material edge coated by the protected surfaces, in order to make the interface air being push out unceasingly between the interfaces. Pushing the materia。
