Before the insulati2、on lay on, make sure the steel surface being level smoothly. The adhesive mortar shall be double component, and the density shall be proper. After fabricated this adhesive mortar, it shall be used up within 30 minutes. To avoid this mortar get solid before using up, the construction speed shall be a3、ccurate estimated. And then fabricate mortar quantity according to estimated construction speed so as to prevent waste. After this mortar dry completely, the PIR or PUR can be sticked on. 4.1.4 施工時采用從中心向四周依次環形的施工方法；每天的工作必須完成整圈PIR 和 FIBAROLL 的施工，用鋁鉑粘貼接口處，及時密封好，以防止雨水滲入。 During construction, the sequen4、ce is from the center to the circumference; each day shall finish overall ring of PIR and FIBAROLL layer. The butt joints shall be seal by aluminum foil so as to avoid water leakage in. 4.1.5 聚氨酯弧板下料時應充分考慮支撐環位置和尺寸，將搭縫排布在支撐環位置。 When fabricating the PIR materials, the supports position and dimension s5、hall be taken into consideration. The butt joints shall be arranged near the support ring. 4.1.6 在預制好的絕熱材料（PIR）與罐體接觸面四周均勻滿涂粘接劑（膠泥） ，且接觸面中間均勻涂抹五點，保證與罐體表面密實、牢固的粘貼；粘貼好的聚氨酯弧板接縫應緊密均勻，并用膠泥嚴密填充、找平。 Brush the adhesive agent on the PIR material, make sure the faces connected with roof plate and other PIR sha6、ll be completed brushed. And the interface with steel plate shall be brushed 5 points evenly so as to make sure it could stick firmly; the sticked on PIR shall be tight and smoothly. Where not level shall be fill with adhesive mortar and keep level. 4.1.7 聚氨酯弧板粘貼后將縱橫搭縫用 PAP 膠帶密封、壓實。 After sticked on7、 the PIR board, the vertical joints shall be seal with PAP Band and roll smoothly. 4.1.8 在支撐環處弧板粘貼完成后，安裝不銹鋼鋼帶，用自攻螺釘將不銹鋼鋼帶固定在支撐鋼件上， 安裝時確保鋼帶將弧板妥善固定，無縫隙。粘貼FIBAROLL 之前應將鋼帶表面用稀釋劑擦拭干凈， 用過的鋼帶應用拋光機處理表面，然后再用稀釋劑擦拭。 After sticked on the PIR board around the support ring, install the stainless stell band on the8、 support device with crew. When install the stainless steel band, make sure the PIR is sticked firmly and without any gap. Prior to stick FIBAROLL on, the stainless steel shall be cleaned. The used band shall be grinded and clean with thinner. CSPC Nahai Petrochemicals Project- Intermediate and Prod9、uct Tanks GDCC PR- GDCC- 0000- 3079 Rev. A Page 4 of 6 Contract No.: C2- WHPE- CSPC- 0037 I/P Tank Insulation Rework Procedure 4.1.9 外保護層（FIBAROLL）使用前應用黑膠帶或無破損紙箱密封妥善保管，施工使用前應仔細檢查。 The FIBAROLL is packed in paper box with black band. Prior to use, check the package carefully. 4.1.10 粘貼保護層前應準確測量并在下料工棚10、內放樣后將 FIBAROLL 裁切成所需尺寸，下料時應充分考慮支撐環位置和尺寸，將搭縫排布在支撐環位置；加工過程中應注意避光， 加工過的材料應在規定時間內及時完成施工； Before stick the protection layer, measure it carefully and cut it into the shape required, which shall be guided by sample. The support ring position and dimension shall be taken into consideration, and the butt jo11、int shall be arranged under the support ring; during cutting process, the light shall be avoided. And the fabricated material shall be used up in the fixed period. 4.1.11 粘貼外保護層（FIBAROLL）前應保護安裝好的絕熱層弧板表面，保持其表面平整、干凈，如有污漬應及時處理干凈。 Before lay on the protection layer (FIBAROLL), the insulation layer surfa12、ce shall be protected and under sound condition. Keep the surface level and clean, once find the dirts, remove it immediately. 4.1.12 FIBAROLL 接縫處采用搭接條粘貼在絕熱層表面，再粘貼大塊 FIBAROLL硬化膜，FIBAROLL 應裁剪成合適尺寸，確保每一塊 FIBAROLL 與 100mm寬的 FIBAROLL 搭接條搭接寬度都為 50mm。搭接縫隙要平整、均勻并環環相扣。 For the joints of FIBAROLL, use the jo13、int bar to stick on the insulation surface, and another big piece of FIBAROLL shall be applied on it. The FIBAROLL shall be cut into accurate dimension. Make sure that each FIBAROLL have overlap joints of 50mm. The overlap joints shall be level and evenly. 4.1.13 粘貼施工時，粘貼后要用特制滾筒碾壓平滑，確保保護層與絕熱層的均勻、牢固、14、密實粘貼；應特別注意接縫部位的平整及嚴密性。 During the sticking construction, the sticky parts shall be rolled smoothly. Make sure that the protection layer could sticked with the under layer firmly. The tightness and smooth of the overlap joints shall be ensured. 4.1.14 如外保護層 FIBAROLL表面接頭有細小裂縫或翹曲等缺陷時， 可采用 fibagel FR UV15、(光硬化聚酯膠泥) 進行填充、修補。 If find tiny crack or warp at the FIBAROLL joints, use FIBAGEL FR UV to fill and repair. 4.1.15 粘貼好的 FIBAROLL 應在其固化一段時間后而完全固化以前，揭除其表面的塑料薄膜；該時間安排有經驗豐富的施工人員進行掌握，時間適當，保護層表面才平滑、光亮。 After sticked the FIBAROLL and cured a certain period, the plastic film on the CSPC Nahai Petrochemicals16、 Project- Intermediate and Product Tanks GDCC PR- GDCC- 0000- 3079 Rev. A Page 5 of 6 Contract No.: C2- WHPE- CSPC- 0037 I/P Tank Insulation Rework Procedure surface shall be removed. This certain period shall be controlled by experienced and skilled personnel. Proper period could ensure the smooth 17、and level surface of FIBAROLL. 4.1.16 罐頂為外網架結構的儲罐，其罐頂被網架角鋼分成小塊方格，施工應注意其與其他罐頂的不同，這些儲罐的罐頂弧板應下成與網架方格尺寸相同，粘貼時注意與網架角鋼的接縫應緊密。聚氨酯材料粘貼后還要以 PS 板切成同樣尺寸將網格空隙填滿并用膠泥抹縫找平，使其上表面與網架角鋼齊平，之后安裝不銹鋼帶，最后粘貼 FIBAROLL 保護層。 For the tanks with external roof structure, the tank roof have been divided into many small grid. When18、 carry out construction on these tanks, special care shall be taken. The PIR dimension shall be the same as the grid dimension. When stick the PIR materials, the gap between angle bar and joints shall be tight. After sticked the PIR on the steel surface, same dimension of PS board shall be lay on th19、e PIR and the gap between grids shall be filled with adhesive mortar and keep level. Till the PS surface is at the same level with angle bar, and then the stainless stell band could be installed. Finally, the protection layer (FIBAROLL) can be applied. 4.1.17 罐沿的施工應特別注意其防水性，因其處于罐頂與罐壁的交界點，施工時罐壁四周絕熱材料20、（PIR）的粘貼應距離罐頂四周罐沿 50mm，該部分絕熱材料（PIR）應與罐壁之間滿膠粘貼，保護層（FIBAROLL）應裁成 50mm 寬長條，粘貼與罐壁與罐壁四周絕熱材料（PIR）上部，然后用特制成型絕熱材料（PIR）安裝于罐沿上，中間用特制材料填平。保護層 FIBAROLL 底邊與罐壁保溫層搭縫，搭縫采用上縫壓下縫（順雨水方向）的方法；上層于罐頂保溫層搭接，搭縫也是上縫壓下縫（順雨水）方向；避免雨水侵入。 The water- proof function of the connection between roof and shelll shall take more care. Bec21、ause this parts is between the shell and roof, make sure that the PIR materials shall be 50mm away from the tank roof circumference. This parts shall be fully brushed adhesive agent. And the FIBAROLL shall be cut into piece with 50mm width and stick it on the top of PIR. The fabricated parts for upp22、er ring could installed then. The FIBAROLL bottom of upper ring shall over lap on the shell insulation layer. Then the joints shall could comply with the rain water flow direction. And so the rain water could not leak into the insulation layer. 4.1.18 罐頂保溫層施工完畢后，應全面檢查，如發現有翹邊或有氣泡現象，用壁紙刀進行修理后，再用特制膠進行涂23、抹、找平。 After the roof insulation layer finished, check it completely. If find any wrap of air bubble, use small knife to repair it and use the special adhesive agent to spray on it. And finally make sure keep level. 5 保溫工程質量措施保溫工程質量措施 Insulation Quality Measure 祥細質量控制和檢查要點請見絕熱工程質量檢測和試驗計劃 （PL-GDCC-00024、0-0009） The detailed quality control and inspection points could refer to Insulation Project Quality CSPC Nahai Petrochemicals Project- Intermediate and Product Tanks GDCC PR- GDCC- 0000- 3079 Rev.
