聚氨酯屋面防水涂料防水失败的原因
1、材料劣质化:由于市场上防水材料价格竞争,导致很多国内聚氨酯材料生产厂商在屋面隔热防水材料上偷工减料,这将使防水材料自己性能降落,导致防水失败。
2、底层未清洁干净:由于在防水施工之前,必须将基面清洁干净,且尽量不要有粉尘与松动物质,否则就会出现防水层与下层黏结不牢固的征象,留下渗漏隐患。
3、底层有水气:由于聚氨酯防水涂料为油性的彩钢屋面防水材料,山西彩钢瓦,所以在施作前必须确认基面是否干燥,否则防水做完后,水气被包裹在里面,经由日照转换成巨大力量的蒸汽,将造成聚氨酯防水层的剥离。
4、聚氨酯防水涂料防水层过薄:聚氨酯防水层必须达到肯定的厚度才有防水结果,由于聚氨酯材料自己仍有较低的吸水特征,倘使防水层厚度不足(百度网站排名),经过连日的滂湃大雨,雨水透过聚氨酯防水层至底部,经由好气候的日照,仍会在底部产生水蒸气,造成防水层剥离。能在所有的转角处黏贴防水聚酯布进行加强处理,以防止聚氨酯防水层断裂造成渗漏。
5、施工经验不足:屋面隔热防水施工由防水专业施工队伍进行操作,不能去五金建材店里随便买些防水材料来涂。防水施工之前需细心判断渗漏原因,再加以解决。

伸缩缝屋顶防水堵漏的施工方案
1、下层要求:用切隔机将伸缩缝两边各50cm处切开(防止打錾时损坏相邻的大理石),然后将切隔处和伸缩缝之间的大理石及砂浆层打掉,直到下层(混凝土楼板面)清理干净。
1, basic requirements: cut machine will be open on both sides of the expansion joint at 50cm (adjacent to prevent damage of the marble, hit the chisel) and then cut and the joints between the marble and the mortar layer, until the base (concrete floor) clean.
2、将伸缩缝两边10cm宽打“V”形模垂深5cm。
2, the expansion joint on both sides of the width of the 10cm 'V' shape deep 5cm.
3、用水泥砂浆将打成的“V”形两侧找平层。
3, with cement mortar will be labeled 'V' shape on both sides of the leveling layer.
4、在伸缩缝底部用50×50cm遇水膨胀止水条嵌底。
4, at the bottom of the expansion joint with 50 * 50cm water expansion sealing strip.
5、用双组份聚氨酯密封膏将止水条与结构层密封、压实。
5, the use of two-component polyurethane sealant to seal the water seal and structural layer, compaction.
6、铺设三元乙丙橡胶屋顶防水卷材。
6, the laying of three ethylene propylene rubber waterproofing membrane.
(1)下层清理。将下层外观突出物等铲平,并将尘土杂物彻底清扫干净。
(1) grassroots clearance. The surface of the base surface, such as shovel flat, and the dust debris thoroughly clean.
(2)涂下层处理剂。下层处理剂采用涂刷法施工,涂刷应均匀同等。
(2) coating agent. Primary treatment agent using brushing method construction, brushing should be uniform.
(3)涂下层胶粘剂。基底胶粘剂使用之前,彩钢瓦防腐喷漆翻新,需搅拌均匀方可使用,分别涂在下层和卷材底面。涂刷应均匀,不漏底,不堆积。
(3) coating base adhesive. Before using the base adhesive, it is necessary to stir evenly, and then apply to the base and the bottom surface of the coil. Brushing should be uniform, no leakage, no accumulation.
(4)铺设卷材。涂胶20分钟左右,基本不粘手后,用手一边压一边驱除空气,粘合后应再用压辊滚压一遍(广州礼品公司),粘结牢固不翅边,不起鼓,然后用聚氨酯密封膏封口。
(4) laying of coiled material. Glue 20 minutes or so, the basic non stick hand, while pressing the side of the hand to remove the air, the adhesive should be used after the pressure roller rolling again, firmly bonded to the edge of the wing, can not afford to drum, and then sealed with polyurethane sealant.
7、试水24小时后,做屋顶防水保护层。
7, test the water for 24 hours, do waterproof protective layer.
8、铺设大理石用1:2的水泥砂浆摊平约20毫米(网页设计价格),接着将大理石呈水平状盖上,要轻拿轻放,不要让利器划伤外观,并用手轻压或用橡皮锤轻轻敲击大理石(成都人事考试网首页),务必使之平整,并与地面粘结坚固,不出现闲暇,否则经人踩踏容易断裂。铺设时要随时用棉丝之类的软性布将缝中挤出的浆液擦干净。铺设完后,可在板面定期找蜡,确保其晶亮的光泽。
8, the laying of 1:2 cement mortar with marble paved ca. 20 mm, then the marble horizontal cover, tohandlegentlyand, don't let the scratched surface, and gently press or with a rubber hammer gently tap to make sure the smooth marble, and the ground is not strong bond, void, or by trampled to fracture. Laying at any time with a soft cloth, such as cotton yarn will be squeezed out of the slurry in the seam clean. After the laying of the board can be on a regular basis to find the wax, to ensure its shiny crystal luster.
屋顶防水补漏时的涂料的性能
⑴屋顶防水涂料在固化前呈浓厚状粘稠液态,因此,屋顶防水堵漏时不仅能在水平面,而且能在立面、阴阳角及各种复杂外观,形成无接缝的完备的屋顶防水膜;
The waterproof coating is viscous liquid before curing therefore can not only in the horizontal plane and waterproof, the facade, yin and yang angle and complex surface, forming a waterproof membrane seamless integrated;
⑵屋顶防水堵漏时无需加热,既削减环境污染,又便于操作,改善劳动条件;
The waterproof plugging without heating, reduce the environmental pollution, and easy to operate, improve working conditions;
⑶形成的屋顶防水层自重小,分外适用于轻型屋面等屋顶防水。
The weight of the waterproof layer to form a small, especially suitable for lightweight roofing waterproof.
⑷形成的屋顶防水膜有较大的延长性、耐水性和耐侯性,彩钢瓦专用修补漆,能适应屋顶防水堵漏下层裂缝的细小的转变。
The formation of waterproof membrane has great extensibility, water resistance and weather resistance, can adapt to the crack waterproof small changes base.
⑸涂布的屋顶防水涂料,既是屋顶防水层的主体材料,又是胶粘剂,故粘结质量容易保证,屋顶防水堵漏时维修也比较简便。尤其是对于下层裂缝、施工缝、雨水斗及贯穿管四周等一些容易造成渗漏的部位(网络营销培训),极易进行加强涂刷、贴布等作业。
The coated waterproof coating, waterproof layer is the main material, and adhesive, so the bonding quality is easy to guarantee, waterproof maintenance is relatively simple when. Especially for the grass-roots cracks, construction joints, and other parts of the rain et through the pipe and other easily lead to leakage of the site, it is easy to enhance the paint, cloth and other operations.
⑹屋顶防水堵漏时必须采用刷子等逐层涂刷,故屋顶防水膜的厚度很难做到像屋顶防水卷材那样均一,屋顶防水膜的质量易受施工条件影响。因此,屋顶防水堵漏时选用屋顶防水涂料时,须认真了解材料的性子和特性、使用方法、低单位面积用量和重复涂、刮的需要性(营销策划),彩钢瓦用什么漆,并必须认真考虑屋顶防水层各个细部的加强处理
It must be waterproof plugging using a brush and scraper by brushing or scraping, the waterproof film thickness is difficult to do so even like waterproof material, the quality of waterproof membrane easily influenced by construction conditions. Therefore, the waterproof plugging waterproof coating, we must be aware of the nature and characteristics, material usage, the minimum unit area amount and repeated coating, scraping the necessity, and must be carefully considered each detail of the enhancement of waterproof layer。
