    环氧地坪施工时地面潮湿怎么处理?

    环氧地坪是底层房间与土层相接触的部分,它承受底层房间的荷载,要求具有一定的强度和刚度,并具有防潮、防水、保暖、耐磨的性能。地层和建筑物室外场地有密切的关系,要处理好环氧地坪与平台、台阶及建筑物沿边场地的关系,使建筑物与场地交接明确,整体和谐。众所周知,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,会使环氧地坪出现涂膜附着力差、表面鼓泡、脱层等不良现象。

    Epoxy floor is the contact part between the ground floor and the ground floor. It bears the load of the ground floor, requires certain strength and rigidity, and has the properties of moisture-proof, waterproof, warmth-keeping and wear-resisting. The stratum is closely related to the outdoor site of the building. We should deal with the relationship between the flat and the platform, the steps and the site along the edge of the building so as to make the connection between the building and the site clear and harmonious as a whole. It is well known that the moisture content of concrete used in epoxy floor paint construction should not be higher than 8%. Excessive moisture content will seriously affect the construction quality of epoxy floor, which will lead to poor film adhesion, surface bubbling, delamination and other undesirable phenomena. 环氧地坪出现返潮主要有几方面原因:

    There are several main reasons for the moisture regain of epoxy floors:


    (1)一是春末夏初,气温升高,春雨绵绵、空气湿度大,致使室内空气达到饱和状态;二是地面温度升高慢,在短时间内尚未提高。当潮湿饱和空气流过低温的地面上时,产生表面凝结。这种现象俗称返潮。土层,当土质好时宜浅埋,反之,基础埋深宜加大。

    (1) In the late spring and early summer, the temperature rises, the spring rain is continuous and the air humidity is high, which causes the indoor air to reach saturation state; secondly, the ground temperature rises slowly and has not increased in a short time. Surface condensation occurs when moist saturated air flows over low-temperature ground. This phenomenon is commonly known as the tide. When the soil is good, it should be buried shallowly. On the contrary, the depth of foundation should be increased.


    (2) 地下水位。基础最好置于地下水位以上。

    (2) Groundwater level. The foundation should be above the groundwater level.


    (3) 冻结深度。基础埋深应大于土层冬天的冻结深度。

    (3) Freezing depth. The depth of foundation should be greater than the freezing depth of soil layer in winter.

    环氧地坪施工地面潮湿怎么处理?

    How to deal with the wet ground of epoxy floor construction?


    1、做防水层: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。

    1. Make waterproofing layer: For concrete foundation with high water content and rising trend of water content, professional waterproofing layer is needed to prevent late seepage from leading to floor failure.


    2、保持施工现场通风: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。

    2. Maintain ventilation in construction site: keep ventilation in construction site. Circulating air flow can accelerate the volatilization of moisture in concrete base surface, which is conducive to improving the bonding force between epoxy floor paint and base.


    3、加热:提高混凝土基面温度提高可以加快水分的蒸发。广州力特克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。

    3. Heating: Increasing the temperature of concrete base can accelerate the evaporation of water. Guangzhou Litek suggests using air heating or radiation heating instead of using fire source heating, because fire source heating can increase the temperature of fog point in air and make water vapor condense in concrete.


    4、透湿系统: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。

    4. Humidity permeability system: The moisture permeability system has a very high water permeability, which can ensure that water vapor on the base surface escapes through the coating and avoid the foaming and falling off of the coating. It is suitable for the base surface which can not be installed with waterproof layer.
