   家电彩涂板厂家在设计的过程中屋面坡度过小,造成雨水不能及时排到天沟,使得屋面出现积水,排水不顺畅,造成屋面渗水:天沟横向没有坡度,天沟落水口设计不合理等情况遇到大雨时造成天沟积水排不出往天沟内檐沟返水:在旖工时天沟防腐不到位,导致天沟生锈腐蚀,或有垃圾等堵塞落水口等情况,都有可能造成漏水或返水的情况发生;房屋在安装和使用过程当中对屋面的踩踏导致紧固件的松动。紧固件防水垫的老化等导致紧固件处漏水;在屋面板上开孔,安装各种风机、排气管道等四周的缝隙处防水处理不好;在使用过程中由于外部环境的影响,风荷载,雪荷载,热胀冷缩等造成屋面板的变形,造成搭接处缝隙扩大,破坏原有的防水处理而出现漏水;施工过程中防水材料选择的不合理和老化等等。
       那我们就要选择好的防水材料来杜决屋面漏水的问题,落水指出防水材料要具备以下性能才可以:
     家电彩涂板厂家在金属表面要有良好的粘结性能,不能脱落;要有良好的弹性和抗断裂拉伸强度以适应屋面的各种震动和位移;低温柔性,以保证在低温状态下的产品性能;要有良好的耐侯性;抗紫外线老化;要有良好的透气性和呼吸性;要有良好的适应各种气候的特性,使用的温度范围较大,以保证产品在高温和低温下的性能以及温差或骤冷骤热的要求;对各种异型部位要能做到无缝处理;安全环保、施工简单等。

Horizontal and vertical joints of metal plates, ridge cover plates, fasteners, gutter outfalls, joints of gutters and roof plates return water inward, high and low spans, joints of roof plates and wall plates, joints of parapets and metal plates, leakage of protruding parts of metal roofs (such as protruding pipes and fan openings), leakage of edges of daylighting belts, leakage around walls and windows Etc.

In the process of design, the roof slope is too small, which causes the rainwater can't be discharged to the gutter in time, which causes ponding on the roof, and the drainage is not smooth, which causes water seepage on the roof: there is no slope in the gutter crosswise, and the gutter outfall design is unreasonable, etc. in case of heavy rain, the ponding on the gutter can't be discharged to the gutter in the gutter, which causes rust and corrosion of the gutter, or There are garbage and other situations such as blocking the water outlet, which may cause water leakage or backflow; the house tramples on the roof during the installation and use process, resulting in the loosening of fasteners. The aging of fastener waterproof pad causes water leakage at the fastener; the waterproof treatment at the joints around the roof panel, installation of various fans, exhaust pipes, etc. is not good; the deformation of the roof panel caused by the impact of the external environment, wind load, snow load, thermal expansion and contraction, etc. during the use process, causes the expansion of the joints, damages the original waterproof treatment and water leakage; construction Unreasonable selection and aging of waterproof materials in the process of construction.
Then we have to choose a good waterproof material to solve the problem of roof leakage. Waters pointed out that the waterproof material should have the following properties:
The metal surface shall have good bonding performance and shall not fall off; shall have good elasticity and tensile strength to adapt to all kinds of vibration and displacement of the roof; shall have low temperature flexibility to ensure the product performance at low temperature; shall have good weather resistance; shall be resistant to ultraviolet aging; shall have good air permeability and breathability; shall have good characteristics to adapt to all kinds of climate and be used The temperature range is large to ensure the performance of the product at high and low temperature and the requirements of temperature difference or sudden cooling and heating; seamless treatment shall be achieved for various special parts; safety, environmental protection, simple construction, etc.
