环氧地坪漆施工基面混凝土的含水率一般不得高于8%,过高的含水率会严重影响环氧地坪的施工质量,会使地坪出现涂膜附着力差、表面鼓泡、脱层等现象出现,所以不宜施工。

基面渗水环氧地坪起泡脱落

 Epoxy floor paint construction the moisture content of the base concrete shall not be higher than 8%, high moisture content will seriously affect the construction quality of epoxy floor paint, can cause a poor coating adhesion, surface ground bubbling, delaminating phenomenon, should not be so construction.

The epoxy ground surface of the base surface is peeling off

干燥、平整、有一定粗糙度的地面是最佳施工基面。那遇到含水率较高的混凝土基面该怎样处理呢?

   Dry, smooth and certain roughness ground is the best construction base surface. So how do you deal with a concrete base with high water content?

1做防水层

1. Waterproof layer

对于含水率较高,且含水量有不断上升趋势的混凝土基面,需要做专业的防水层,防止后期渗水而导致地坪失效。

 For the concrete base with high moisture content and rising trend of water content, it is necessary to make a professional waterproof layer to prevent the ground level from being lost due to the late seepage.

2保持施工现场通风

Keep the construction site ventilated

施工现场保持通风状态,空气的循环流动可以加快混凝土基面中水分的挥发,有利于提高环氧地坪漆与基面的粘结力。

 The air circulation can accelerate the volatilization of water in the concrete base surface, which is beneficial to improve the adhesion of epoxy floor paint and base surface.

3加热

3 the heating

提高混凝土基面温度提高可以加快水分的蒸发。耐迪斯建议使用空气加热或是辐射加热,不能采用火源加热,因为火源加热会增加空气中雾点温度,使水汽在混凝土中凝结。

 Increasing temperature of concrete base surface can accelerate the evaporation of water. It is recommended to use air heating or radiation heating, which cannot be heated by the source of the fire, because the heating of the source increases the temperature of the fog point in the air, so that the water vapor condenses in concrete.

4透湿系统

4 moisture permeable system

透湿系统有极高的水分透过率,可保证基面水汽透过涂层逸出,避免涂层起泡脱落,适用于无法安装防水层的基面。Nds106 环氧树脂水性环保型地坪有相当好的透水性,适合比较潮湿的地下室、食品厂等特殊场所。有条件的企业在施工前如果需要的话还是尽量装专业的防水层,防止日后环氧地坪出现问题。

The moisture permeation system has a high water penetration rate, which can ensure that the water vapor of the base surface is escaped through the coating and avoid the peeling off of the coating, which is suitable for the base surface that cannot be installed in the waterproof layer. Nds106 epoxy resin waterborne environment has a good water permeability, suitable for humid basement, food factory and other special places. If necessary, the qualified enterprises should try to install a professional waterproof layer before construction, and prevent the problems of epoxy floor in the future.
