安徽真石漆浅谈防水材料影响聚氨酯防水涂料防水效果的五大因素

 

1、确认干燥

聚氨酯防水涂料的防水材料是油性的,所以在施工前必须确认是否干或防水整理,水分是包裹在里面,通过蒸汽转化为阳光的力量,造成剥离的聚氨酯防水层。

2、材料低劣

由于进入壁垒较低,价格竞争等问题的防水材料,国内生产厂家在聚氨酯防水材料上的切削角,这使得本身防水涂料的性能下降,导致防水失效

3、底座清洁

防水施工前的重要工作就是清理的基础上,对聚氨酯防水涂料施工是无法避免的,所以在做防水施工之前一定要把表面清理迅速,确保无浮尘,沙子和其他松散的表面材料,否则会有防水层和基础层不稳定的现象,从而导致泄漏。

4、缺乏施工经验

防水施工是最好的防水专业施工队经营,不能去五金建材线购买一些防水材料油漆。防水浇注前需要仔细确定渗漏原因,然后加以解决。

5、防水层厚度控制

聚氨酯防水层必须达到一定厚度具有防水效果。聚氨酯材料本身还是比较低的吸收特性,如果防水层的厚度是不够的,雨水通过聚氨酯防水层的底部,阳光会产生水蒸汽在底部,造成防水层剥离。同时,聚氨酯防水涂料是不是画尽可能厚,因为聚氨酯防水涂料容易成膜过程中产生的反应的二氧化碳和其他气体,如果涂层太厚,产生气泡,从而影响防水效果。



1, confirm the dry


Polyurethane waterproof coating waterproof material is oily, so before the construction must confirm whether dry or waterproof finish, moisture is wrapped inside, through the steam into the power of sunshine, causing peeling polyurethane waterproof layer.


2, material inferior


Due to the low barriers to entry, price competition and other issues of waterproof materials, the production of domestic manufacturers in the polyurethane waterproof material on cutting corners, which makes itself waterproof coating property decreased, resulting in the failure of waterproof

3, the base is clean


Waterproof construction before the important job is to clean up the base, construction of polyurethane waterproof coating can not be avoided, so doing waterproof construction must take before surface cleaning up quickly, ensure no floating dust, sand and other loose surface material, otherwise there will be a waterproof layer and base layer unstable phenomenon, so as to cause leakage.


4, lack of construction experience


Waterproof construction is the best waterproof professional construction team to operate, can not go to the hardware building materials line to buy some waterproof materials to paint. Waterproof cast before the need to carefully determine the cause of leakage, and then to be resolved.


5, the waterproof layer thickness control


Polyurethane waterproof layer must reach a certain thickness to have waterproof effect. The polyurethane material itself is still relatively low absorption characteristics, if the thickness of waterproof layer is not enough, the rain through the polyurethane waterproof layer to the bottom, the sunshine will produce water vapor at the bottom, causing the waterproof layer peeling. At the same time, polyurethane waterproof coating is not painted as thick as possible, because the polyurethane waterproof coating is easy to produce carbon dioxide and other gases in the reaction during the film forming process, if the coating is too thick to produce bubbles, thus affecting the waterproof effect.
