铝板生产厂家帮你分析铝板幕墙的质量通病
　　The aluminium plate manufacturer helps you to analyze the common quality defects of aluminium plate curtain wall一、板面不平整、不竖直、接缝宽窄、上下不分歧1、缘由：骨架的程度、垂直超差，立面不平，板面装置超差，孔眼错位；2、防治措施:
　　First, the board surface is uneven, not vertical, the joint width is narrow, the top and bottom do not diverge. 1. Reasons: skeleton degree, vertical overshoot, the elevation is uneven, the board surface device is overshoot, hole dislocation; 2. Prevention and control measures:
　　（1）从装置埋件和收缩螺栓开端，必需认真操作。骨架装置时程度、垂直拉线，平面要平，然后以经纬仪检查，停止工序验收；（2）板和骨架定位，钻孔必需精确；（3）板装置时，不可随意，必按计划和弹线位置停止装置。在装置前应对板块尺寸，外形停止检查，检查无误方可装置。
　　(1) From the beginning of the device buried parts and shrinkage bolts, it must be carefully operated. When the skeleton device is installed, the degree, vertical pulling line and the plane should be flat, then the theodolite is used to check and stop the acceptance of the process; (2) the positioning of the plate and the skeleton must be accurate; (3) when the plate device is installed, it should not be arbitrary, and the device must be stopped according to the plan and the position of the elastic line. Before the device, the size and shape of the plate should be stopped to check, and the device can only be installed if the check is correct.
　　二、接缝密封不严，不平整，有气泡和渗水现象1、缘由:
　　Second, the seams are not tightly sealed and uneven, and there are bubbles and seepage phenomena. 1. Reasons:
　　（1）嵌缝时末用聚乙烯泡沫将板面后堵紧，当用嵌缝枪灌注密封胶时末构成一定压力，致使和板缝粘结不牢，密封不严；（2）操作工人操作不纯熟，嵌缝时枪口距嵌缝处的间隔不分歧，压力不平均，致使粗细不匀，接头多，带入空气，形成密封胶的外表不平直，有气泡和渗水现象；（3）资料问题：硅酮密封胶质量存在问题。
　　(1) at the time of caulking, it will be blocked with polyethylene foam. When the sealant is poured into the sealant, it will form a certain pressure, resulting in a certain pressure on the seams. The sealing is not strict. (2) the operator is not skilled in operation, and the gap between the muzzle and the gap is different when the joint is slit. The pressure is uneven, resulting in uneven thickness and more joints. There are bubbles and seepage; (3) data problems: there are problems in the quality of silicone sealant.
　　2、防治措施:
　　2. Prevention and control measures:
　　（1）选材要好，工具性能好；
　　(1) Good material selection and tool performance;（2）认真塞入密封填充物，填充面离板面间隔坚持分歧，嵌入密封胶深度分歧，使接缝密实，缝面平直；（3）操作工人技术纯熟，把稳嵌缝枪，坚持速度匀，间隔分歧，随嵌随扫除空气，一旦呈现气泡就将其捅破，并用抹子压平把气扫除。
　　(2) Carefully insert the sealing filler, and stick to the difference between the filling surface and the plate surface, and insert the difference of sealant depth to make the seam dense and flat; (3) The operator is skilled, and sticks to the seam stabilizing gun at a uniform speed, and the gap is different. As the air is swept away, once the air bubbles appear, they are punctured and the air is swept off with a plaster.
　　三、收口处置不结实，不平顺，不密封
　　Third, the closing disposal is not firm, uneven and sealed.
　　1、缘由:末按请求施工，装置不细致，办法不当。
　　1. Reasons: At the end of the construction according to the request, the installation is not meticulous and the method is inappropriate.
　　2、防治措施:
　　2. Prevention and control measures:

                                 
　　（1）施工前做好收口计划，对不同构造、条件采用合理的收口计划；（2）装置时严厉操作，控制要领。
　　(1) Make a good closing plan before construction and adopt a reasonable closing plan for different structures and conditions; (2) Strict operation and control essentials during installation.
　　四、外表污染，有凹痕
　　4. Appearance contamination with dents
　　1、缘由:
　　1, reasons:
　　（1）维护膜撤除过早，维护废品措施不当；
　　(1) The removal of maintenance film is premature and the measures for maintaining waste products are inappropriate;（2）下道工序施工时对废品维护不当，撞击板面形成。
　　(2) When the next working procedure is constructed, the waste products are improperly maintained and the impact plate surface is formed.
　　2、防治措施:
　　2. Prevention and control measures:
　　（1）拆维护膜不要过早，在拆脚手架时撤除为好；（2）工作中制定出可行的废品维护措施；（3）关于污染处及时清算，擦洗洁净。
　　(1) Do not dismantle the maintenance film too early, it is better to remove the scaffolding; (2) work out feasible waste maintenance measures; (3) timely liquidation of the contaminated areas, clean and scrub.
