彩钢瓦专用防水卷材施工工艺

1、 防水底层工作条件：1、彩钢瓦基面无灰尘、松散。基础表面应无积水。如需加固，防水层合格后方可施工3.当彩钢瓦缝隙超过03mm时，应进行加固处理，处理完毕后方可施工4.阴阳角处应加铺一层，堆放立面及平面阴角、立面阴阳角5.早晨彩钢瓦表面有露水时，暂停施工6.严冬施工彩钢瓦应涂底层处理剂

2、操作工艺：1.彩钢瓦清理基层表面：用支撑布将旧彩钢瓦表面的灰尘擦干净。如有锈蚀，应除锈，使其平整干净2.彩钢瓦补层：在阴阳角、通风口、天沟等处补层，补层宽度15cm-30cm，并沿阴阳角中心轴线延伸3.大面积施工：A。先弹好基准线，使卷材整齐美观。b。铺平卷材，将卷材与施工位置对齐，从两端卷起卷材。c。从其上切下阻隔纸，取下阻隔纸，尽量揉搓卷材，使卷材平整4.要求：铺设彩钢瓦专用防水卷材时，应从下坡方向开始施工。垂直墙由高到底b铺设。将顶卷内的空气扫净，用压卷机将顶卷内的空气压下，使顶卷牢固粘结。当温度较低时，有必要将底漆与线圈d一起刷。搭接接头长边3cm-8cm，短边10cm。。e。搭接接头短边的搭接接头、搭接接头的端部和搭接接头的相对部位应用密封膏密封。卷材立墙端头原则上用金属条固定在预留槽内，然后用密封膏密封3、铺贴方法：1、满铺方法：在彩钢瓦房表面铺全彩钢瓦专用防水卷材。宜水平敷设，其优点是能完全达到屋面防水防腐的效果。尤其是屋顶的钉孔。大多数的钉子洞在三年后开始渗出。一劳永逸解决问题2：只对缝隙，最好做两次，下一次33厘米，上一次50厘米宽。屋檐应包边两次4、施工注意事项：1：旧屋顶要求不得有灰尘，清洁就行，旧屋顶可用抹布擦拭，如刷处理剂，不宜过厚2：最佳厚度为1.5mm或2mm。胎体的最佳选择在南方3：对于无胎体的施工，最好不要在雾天或暴雨停止时施工。水分会产生气泡4：卷材长边与短边搭接不小于10cm。。5:卷材与卷材、卷材与加强层搭接应牢固，不得有翘边现象。有条件的工程应进行防水试验6.防水层施工完毕后不得打开，因为这种材料是粘结的。时间越长，结合越牢固。如果打开两次，就会出现粘结不实的场面，有必要我们厂刷底处理剂才能彻底粘结。

1、 Working conditions of waterproof bottom layer: 1. The base surface of color steel tile is free of dust and loose. The construction can only be carried out after some looseness treatment 2. There shall be no ponding on the base surface. If it is necessary to reinforce, the waterproof layer can be constructed only after it is qualified 3. When the gap of color steel tile exceeds 03mm, reinforcement treatment shall be carried out, and construction can only be carried out after treatment 4. It is necessary to make additional layers for internal and external corners, pile facade and plane internal corners, internal and external corners of facade 5. In the morning, when there is dew on the surface of colored steel tile, the construction shall be suspended 6. The bottom layer treatment agent shall be applied on the color steel tile for construction in severe winter 2、 Operation technology: 1. Clean the base surface: wipe off the dust on the old color steel tile surface with a supporting cloth. If there is rust, remove the rust to make it flat and clean 2. Make additional layer: additional layer shall be made at the internal and external corners, vents, gutters, etc. the additional layer shall be 15cm-30cm wide and extended along the central axis of the internal and external corners 3. Large area construction: A. snap the datum line first, so the coiled material is neat and beautiful. b. Lay the coiled material flat, align the coiled material with the position to be constructed, and roll up the coiled material from both ends. c. Cut the barrier paper from it, remove the barrier paper and knead the coil as far as possible to make the coil flat 4. Request: when paving the special waterproof coiled material for color steel tile, the construction shall start from the downhill direction. The vertical wall is paved from high to bottom b. Sweep away the air and press the air in the overhead coil with the coil rolling to make the coil firm and bonded c. When the temperature is low, it is necessary to brush the primer together with the coil d. The long side of the lap joint is 3cm-8cm, and the short side is 10cm.. e. the lap joint of the short side of the lap joint, the end of the lap joint and the opposite parts of the lap joint should be sealed with sealing paste. In principle, the coil vertical wall end is fixed in the reserved groove with metal strip, and then sealed with sealing paste 3、 Paving method: 1. Full paving method: pave all color steel tile special waterproof coiled materials on the surface of color steel tile house. It should be laid horizontally, and the advantage is that it can completely achieve the waterproof and anti-corrosion effect on the roof. Especially for the nail hole of the roof. Most of the nail holes began to seep after three years. Solve the problem once and for all 2: Only for slits, it is best to do it twice, the lower one is 33cm, and the upper one is 50cm wide. The eaves should be hemmed twice 4、 Construction precautions: 1: the old roof request must not have dust, clean on the line, the old roof can be wiped with a cloth, if brush treatment agent, not too thick 2: The best thickness is 1.5mm or 2mm. The best choice of carcass is in the south 3: For the construction without carcass, it is better not to construct in foggy days or when the heavy rain stops. The moisture will produce bubbles 4: The lap joint between the long side and the short side of the coiled material shall not be less than 10cm.. 5: the lap joint between the coiled material and the coiled material, and between the coiled material and the reinforcing layer shall be solid, and the phenomenon of edge warping shall not exist. The water shielding test shall be conducted for the project with conditions 6. Don't open the waterproof layer just after the construction, because this kind of material is bonded. The longer the time is, the stronger the bonding is. If open two times on, will appear to bond not solid scene, it is necessary to brush our factory bottom treatment agent can thoroughly bond.
