使用完成前硬化,应准确预估施工速度,根据施工速度掌握胶泥配置量,避免浪费,待胶泥完全硬化后开始粘贴绝热弧板。
Because the joints on roof is butt joints. Before the insulation lay on, make surethe steel surface being level smoothly. The adhesive mortar shall be doublecomponent, 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 usingup, the construction speed shall be accurate estimated. And then fabricate mortarquantity according to estimated construction speed so as to prevent waste. Afterthis mortar dry completely, the PIR or PUR can be sticked on.4.1.4 施工时采用从中心向四周依次环形的施工方法;每天的工作必须完成整圈PIR和FIBAROLL的施工,用铝铂粘贴接口处,及时密封好,以防止雨水渗入。
During construction, the sequence is from the center to the circumference; eachday shall finish overall ring of PIR and FIBAROLL layer. The butt joints shall beseal by aluminum foil so as to avoid water leakage in.4.1.5 聚氨酯弧板下料时应充分考虑支撑环位置和尺寸,将搭缝排布在支撑环位置。
When fabricating the PIR materials, the supports position and dimension shall betaken into consideration. The butt joints shall be arranged near the support ring.4.1.6 在预制好的绝热材料(PIR)与罐体接触面四周均匀满涂粘接剂(胶泥),且接触面中间均匀涂抹五点,保证与罐体表面密实、牢固的粘贴;粘贴好的聚氨酯弧板接缝应紧密均匀,并用胶泥严密填充、找平。
Brush the adhesive agent on the PIR material, make sure the faces connected withroof plate and other PIR shall be completed brushed. And the interface with steelplate shall be brushed 5 points evenly so as to make sure it could stick firmly; thesticked on PIR shall be tight and smoothly. Where not level shall be fill withadhesive mortar and keep level.4.1.7 聚氨酯弧板粘贴后将纵横搭缝用PAP胶带密封、压实。
After sticked on the PIR board, the vertical joints shall be seal with PAP Bandand roll smoothly.4.1.8 在支撑环处弧板粘贴完成后,安装不锈钢钢带,用自攻螺钉将不锈钢钢带固定在支撑钢件上,安装时确保钢带将弧板妥善固定,无缝隙。
粘贴FIBAROLL之前应将钢带表面用稀释剂擦拭干净,用过的钢带应用抛光机处理表面,然后再用稀释剂擦拭。
After sticked on the PIR board around the support ring, install the stainless stellband on the support device with crew. When install the stainless steel band, makesure 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 withthinner.PR-GDCC-0000-3079 Rev. A Page 3 of 6 Contract No.: C2-WHPE-CSPC-0037I/P Tank Insulation Rework Procedure4.1.9 外保护层(FIBAROLL)使用前应用黑胶带或无破损纸箱密封妥善保管,施工使用前应仔细检查。
The FIBAROLL is packed in paper box with black band. Prior to use, check thepackage carefully.4.1.10 粘贴保护层前应准确测量并在下料工棚内放样后将FIBAROLL裁切成所需尺寸,下料时应充分考虑支撑环位置和尺寸,将搭缝排布在支撑环位置;加工过程中应注意避光,加工过的材料应在规定时间内及时完成施工;Before stick the protection layer, measure it carefully and cut it into the shaperequired, which shall be guided by sample. The support ring position anddimension shall be taken into consideration, and the butt joint shall be arrangedunder the support ring; during cutting process, the light shall be avoided. And thefabricated material shall be used up in the fixed period.4.1.11 粘贴外保护层(FIBAROLL)前应保护安装好的绝热层弧板表面,保持其表面平整、干净,如有污渍应及时处理干净。
Before lay on the protection layer (FIBAROLL), the insulation layer surface shallbe protected and under sound condition. Keep the surface level and clean, oncefind the dirts, remove it immediately.4.1.12 FIBAROLL接缝处采用搭接条粘贴在绝热层表面,再粘贴大块FIBAROLL硬化膜,FIBAROLL应裁剪成合适尺寸,确保每一块FIBAROLL与100mm宽的FIBAROLL搭接条搭接宽度都为50mm。
搭接缝隙要平整、均匀并环环相扣。
For the joints of FIBAROLL, use the joint bar to stick on the insulation surface,and another big piece of FIBAROLL shall be applied on it. The FIBAROLL shallbe cut into accurate dimension. Make sure that each FIBAROLL have overlapjoints of 50mm.. The overlap joints shall be level and evenly.4.1.13 粘贴施工时,粘贴后要用特制滚筒碾压平滑,确保保护层与绝热层的均匀、牢固、密实粘贴;应特别注意接缝部位的平整及严密性。
During the sticking construction, the sticky parts shall be rolled smoothly. Makesure that the protection layer could sticked with the under layer firmly. Thetightness and smooth of the overlap joints shall be ensured.4.1.14 如外保护层FIBAROLL表面接头有细小裂缝或翘曲等缺陷时,可采用fibagelFR UV(光硬化聚酯胶泥) 进行填充、修补。
If find tiny crack or warp at the FIBAROLL joints, use FIBAGEL FR UV to filland repair.4.1.15 粘贴好的FIBAROLL应在其固化一段时间后而完全固化以前,揭除其表面的塑料薄膜;该时间安排有经验丰富的施工人员进行掌握,时间适当,保护层表面才平滑、光亮。
After sticked the FIBAROLL and cured a certain period, the plastic film on the PR-GDCC-0000-3079 Rev. A Page 4 of 6 Contract No.: C2-WHPE-CSPC-0037I/P Tank Insulation Rework Proceduresurface shall be removed. This certain period shall be controlled by experiencedand skilled personnel. Proper period could ensure the smooth and level surface ofFIBAROLL.4.1.16 罐顶为外网架结构的储罐,其罐顶被网架角钢分成小块方格,施工应注意其与其他罐顶的不同,这些储罐的罐顶弧板应下成与网架方格尺寸相同,粘贴时注意与网架角钢的接缝应紧密。
