防水涂料的基本性能有哪些

2020-09-04 15:00
   1、防水涂料在常温下呈粘稠液体,经涂布固化后,能形成无接缝的防水涂膜。



  2、防水涂料特别适宜在立面、阴阳角、穿结构层管道、凸起物、下在场所等细部构造处进行防水施工,固化后,能在这些复杂的部位表面形成完整的防水膜。



  3、防水涂料施工属于冷水作业,操作简便,劳动轻度低。



  4、固化后形成的涂膜防水层自重轻,对于轻型薄壳等异型屋面大都采用防水涂料进行施工。



  5、涂膜防水层具有良好的耐水、耐侯、耐酸碱特性和优异的延伸性能,能适应基层局部变形的需要。



  6、涂膜防水层的拉伸强度可以通过加贴台体增强材料来得到加强,对于基层裂缝、结构缝、管道根等一些容易渗漏的部位,极易进行增强、补强、维修等处理。



  7、防水涂膜一般依靠人工涂布,其厚度很难做到均匀一致。所以施工时,要求严格按照操作方法进行重复多遍的涂刷,以保证单位面积内的最低使用量,确保涂膜防水层的施工质量。



  8、采用涂膜防水,维修比较方便。
1, waterproof coating at normal temperature is viscous liquid, after curing, can form no seams of waterproof coating film.

2, waterproof coating is particularly suitable for the facade, Yin and Yang Angle, through the structure layer pipe, raised, under the site and other details of the structure of the waterproof construction, after curing, can form a complete waterproof film on the surface of these complex parts.
3, waterproof coating construction belongs to cold water operation, easy to operate, labor slightly low.

4, after curing the formation of the coating film waterproof layer weight, for light thin shell and other special-shaped roof most use waterproof paint for construction.
5, coating waterproof layer with good water, weather, acid and alkali resistance characteristics and excellent extension performance, can meet the needs of local deformation of the base.
6, the tensile strength of the coating film waterproof layer can be strengthened by attaching platform strengthening materials. For the cracks, structural joints, pipe roots and other parts prone to leakage, it is easy to strengthen, reinforce and maintain.
7, waterproof coating generally rely on manual coating, its thickness is difficult to achieve uniform. Therefore, the construction, the requirements in strict accordance with the operation of repeated brush, in order to ensure the unit area of the minimum usage, ensure the construction quality of coating film waterproof layer.
8, use coating waterproof, easy maintenance.
