Only all involved workers are qualified can they assume the position. The construction safety on site should comply with SH3505-1999 “Technical Specification for Construction Safety in Petrochemical Engineering”（2） 现场需设有堆料棚，防火涂料进入棚内，并要下垫跳板，上盖篷布，堆放整齐，严禁散包受潮。The shelter should be erected to store materials on site. For the fireproof coating in the shed, make sure that there is plank underneath and tarpaulin above. Stack the materials in order. Loose packing and moisture is not allowed.（3） 各种施工机械要检修完毕，试运正常。All construction machines should be maintained and the trial run should be normal.B. 隔热型防火涂料涂装施工的环境条件： Environmental Conditions:（1）.工作场地：涂装工作应尽可能在室外进行，并应保持环境的清洁、干燥，以防止已涂装好的任何表面被灰尘、水滴、焊接下溅或其它脏污粘附在上面而影响质量。 Working place: Try to carry out the painting work outside. Keep the environment clean and dry to prevent that the painted surface being contaminated by dust, water drop, welding slag or other dirt.（2）环境温度：施工进行时的环境温度一般控制在5-35之间（指涂料施工到涂层干燥固化前的整个过程期间）。风速小于5m/s Ambient temperature: The ambient temperature is usually kept at 5-35 for construction (the whole period from the coating work starting till the drying and solidification of the coating). The wind speed should be less than 5m/s.（4） 相对湿度：涂装施工应控制相对湿度在85%以下。当钢构件表面有结露时不宜作业。Relative Humidity: the relative humidity should be controlled below 85% for painting. It is not fit to work if there is dew on member surface.（5） 其它方面：对钢构件需在安装现场进行焊接的部位，应按标准留出规定的长度不涂刷防火涂料，事后进行修补工序。Other factors: For the steel member where needs welding on site, leave the required length not to apply fireproof coating. Then carry out the touch-up procedure later.C涂覆施工 Coating Construction SG本工程隔热型防火涂料采用喷涂与抹涂施工。In this project, the insulation fireproofing coating uses spraying and brushing.基层防锈处理复检Re-inspect the rust-proof treatment of the base layer作好防污措施及脚手架搭建等准备工作Make preparations such as antifouling measure and scaffolding erection, etc.基层防锈表面除污去杂处理Remove the dirt and debris on the rust-proof surface of the base layer作好安全，技术交底工作Carry out safety and technical clarification隔热型防火涂料的施工方法：Construction method of insulation fireproofing coating:a).按生产厂家提供的材料配比,用搅拌机充分搅拌至所需要的稠度和粘度备用. According to the material proportioning provided by the vendor, mix the materials completely to the required consistence and viscosity by the mixer.b）.采用喷涂机具,喷涂或刷涂底层涂料,涂覆率大于70%,相隔24小时后抹涂一层5-10再相隔24小时以上再涂抹一层5-10再相隔24小时以上涂抹至所需厚度 Use the spraying machine to spray or brush the primer painting, covering more than 70%; after 24h, apply a 5-10mm coating; after 24h, apply a 5-10mm coating again; after 24h, apply to the required thickness.D流程如下Procedure：基层除污Remove the dirt of the base第一道底层Prime第二道抹涂Second Coating最后一道抹涂（依据涂覆所需厚度）Last Coating（according to the required thickness）自检Self-inspection交工验收Inspection and acceptance for handover由于在实际施工过程中，受施工的程度、施工面积、构件形状、大小等诸多因素的影响，需要在过程中不断自检，抽点测量厚度，最后对于厚度不足部位加以修补。The actual construction is influenced by many factors, such as construction degree, construction dimension, member shape, size and others, so that self-inspection should be carried out constantly. Check some points for the thickness. At last, for the positions where it is not thick enough, carry out touch-up painting.（三）粘钉与挂网Cohere Forcer and Mesh Binding a).保温钉要求Insulation Nail Requirements：A、粘钉：用万能胶把成品保温钉粘结在构件上，距离300mm×300mm,常温固化时间48小时后再开始挂网. Cohere nail: cohere the fabricated insulation nails to the components by the all-purpose adhesive with space 300mm×300mm. After 48h of solidifying at normal temperature, start to bind the mesh.B、保温钉固定好后，刷涂或喷涂打底料常温48小时后开始挂网，将保温钉压弯把铁丝网固定。After fixing the insulation nails, start to bind the mesh after 48h of the painting or brushing the primer. Fix the wire mesh by bending the insulation nails.C、设备裙座已焊接焊钉或粘接60mm长的保温钉，在第一遍底料干燥后绑扎直径0.5-1mm，洞距20mm×20mm铁丝网。For the equipment skirt which has already welded with welding nail or bonded with 60mm long insulation nails, after the drying of the first primer, fix the wire mesh with diameter 0.5-1mm and hole distance 20mm×20mm.D、以上3条的保温钉横竖间距为300mm左右在型钢转角处必须粘结保温钉或焊钉，以利于铁丝网的紧固。For the insulation nails mentioned in the above 3 items, bond the insulation nails or welding nails at the corner of the shaped steel approximately every 300mm horizontally and vertically to fix the wire mesh.E、加网方法：先量出构件需加网的部位周长，再加1-2个孔径长，把网剪断，透过保温钉把网覆在涂层上，接头用钢丝纽把它们纽在一起压平，在进行下道施工。Mesh binding method: Measure the perimeter of the location which needs mesh binding for the members and extend 1-2 hole diameter. Cut off the mesh and cover the mesh to the coating through the insulation nails. Flatten the joints by steel wire and then proceed the next step.（四）涂料施工 Painting Work a).1搅拌Mixing：防火涂料搅拌必须使用低速砂浆搅拌机，以免涂料中轻骨料过度粉碎影响涂料质量，材料应随拌随用。The low-speed mortar mixer must be used for the fireproof painting to prevent that the medium and lightweight aggregate being over smashed so that the painting quality will be affected. The materials should be mixed only when it is needed. 2 底料配比Primer Painting Proportion： 施工PHA-SW涂料前必须用本涂料与专用底胶配置打底，底料施工配置：专用底胶：PHA-SW涂料：水=1：3：2（重量比）“先放水再放胶后放料”进行搅拌10-15分钟呈均匀稠厚流体无结块即可施工。Prior to use painting PHA-SW, this painting must be mix with special glue as the paint primer. Special glue: painting PHA-SW: water=1：3：2 (proportion by weight). “Put in water first, then the glue and painting at last.” Mix for 10-15 min until the mixture becomes liquid with uniform thickness without agglomeration. Then the coating can start. 3 涂料施工配制Painting Proportion： PHA-SW涂料：水=1：0.9（重量比）“先放水后放料”进行搅拌10-15分钟呈均匀稠厚流体无结块（稠度在8-12CM 范围内）即可施工，搅拌好涂料应在40分钟内完成施工。 Painting PHA-SW: water=1：0.9(proportion by weight). “Put in water first, then put in painting” and mix for 10-15 min till the mixture becomes liquid with uniform thickness without agglomeration (the consistence should be within 8-12CM). The mixed painting should be used within 40 min. b)底料施工Primer Painting：室外厚型钢结构防火涂料底料按要求的配比搅拌均匀后，可采用喷涂施工，喷涂采用大口径的专用喷枪（口径为6-10MM）空气压力为0.3-0.5MPA，涂层厚度为2-3mm均匀覆盖即可。After the primer of outdoor thick steel structure fireproofing coating is mixed according to the requirements, use the special spray gun with big bore (6-10MM) to spray the paint with air pressure 0.3-0.5MPA. The primer should be uniform and 2-3mm thick. c)面料施工Finish Painting Work：室外厚型钢结构防火涂料面料施工必须在底料表干后方可进行。如遇表面过干，施工前需适量喷洒点自来水。施工可采用抹涂或喷涂，抹涂一般采用常规的抹涂工具进行人工抹涂（每道厚度控制在10mm以内），喷涂与底料施工方法相同（每道厚度控制在5mm以内）。The finish painting of the outdoor thick steel structure fireproofing coating should be carried out after the primer surface is dried. If the surface is too dry, spray some water before applying. Brushing or spraying can be used. For the brushing, use the brushing tools manually (the thickness of each layer should be within 10mm). The spraying method is the same as that of the primer (the thickness of each layer should be within 5mm).室外厚型钢结构防火涂料施工时，对涂层作必要的维护，乳突部位及时用抹刀剔除。在施工过程中，施工人员应带探针随时检查涂层厚度，直到符合要求的厚度为止。When doing the outdoor thick steel structure fireproofing coating work, maintain the coating and use the spatula to remove the mastoid points immediately. During the coating, workers should inspect the coating layer thickness all the time with the probe until the thickness is accepted.防火涂料施工时，防火涂层在未固化之前应避免雨淋、水冲和机械撞击，涂层应防止污染和损坏，应做好周围环境的保护。Protect the fireproof coating from rain, water flushing or mechanical collision before solidification. Protect the coating from the contamination and damage. Do well in the environmental protection.五、 质量保证体系图Quality Insurance System项目经理： Project Manager: 项目总工： Chief Engineer: 质量经理安全施工经理防火检查员设备工程师作业班组六、 质量、工期、安全控制 Quality, Construction Duration and Safety Control1、质量控制措施 Quality control measures（1）产品质量控制 product quality control 产品生产格按ISO9002及产品标准：GB14907-2002钢结构防火涂料通用技术条件，每批涂料运场应填写材料报审表附产品质保书，并做抽样检测，作好记录，合格方能施涂，最后一道涂层应采用同一批产品，防止造成工程整体色差。 The product should be in strict accordance with the ISO9002 and product standard: GB14907-2002 “ General Specification of Steel Structure Fire Proof Paint”.
