為什麼环氧地坪漆施工的地面不能含有水分

各種环氧地坪的施工，如果處理不好的話，地面會有水分存在，很多人不知道為什麼地面會有水，你知道地面有水的話對整體的地面施工有怎麼樣的影響嗎?其實地面基層有水分的存在，對我們的施工是不利的，环氧地坪漆施工害怕地面的含有水分。所以施工前一定要處理好地面水分問題，施工前根據地面含水分情況做出一份處理的方案。具體如下：
All kinds of floor construction, if not handled properly, there will be water on the ground. Many people do not know why there will be water on the ground. Do you know how the water on the ground will affect the overall ground construction? In fact, the existence of water on the ground base is not conducive to our construction, and the construction of epoxy floor paint is afraid of the water on the ground. Therefore, before construction, we must deal with the problem of surface water, and make a treatment plan according to the situation of surface water before construction. Specifically as follows: 混凝土含水率應小於9%，否則應排除水分後方可進行塗裝。排除水分的方法有以下幾種：
The moisture content of concrete should be less than 9%. Otherwise, the water content should be excluded before coating. There are several ways to remove moisture:
a)通風：加強空氣循环，加速空氣流動，帶走水分，促進混凝土中水分進一步揮發。
A) Ventilation: Enha印花地坪nce air circulation, accelerate air flow, take away moisture, and promote further volatilization of moisture in concrete.
b)加熱：提高混凝土及空氣的溫度，加快混凝土中水份遷移到表層的速率，使其迅速蒸發，宜采用強制空氣加熱或輻射加熱。直接用火源加熱時生成的燃燒產物(包括水)，會提高空氣的霧點溫度，導致水在混凝土上凝結，故不宜采用。
B) Heating: Increase the temperature of concrete and air, accelerate the rate of moisture migration to the surface of concrete, and make it evaporate rapidly. It is advisable to use forced air heating or radiation heating. The combustion products (including water) produced by direct heating with fire source will increase the temperature of air fog point and cause water to condense on concrete, so it is not suitable to use them.
c)降低空氣中的露點溫度：用脫水減濕劑、 环氧樹脂地板漆除濕器或引進室外空氣(引進室外空氣露點低於混凝土表面及上方的溫度)等方法除去空氣中的水汽。
C) Reducing dew point temperature in air: dehydrating dehumidifier, epoxy floor paint dehumidifier or introducing outdoor air (introducing outdoor air dew point lower than concrete surface and above the temperature) and other methods to remove water vapor in air.
1.中塗層

地面基層有水，對施工的一些影響，以及排除水分的辦法我們都有一些介紹，其實基層排水通過加熱，以此來提高混凝土及空氣的溫度，加快混凝土中水分迅速蒸發，從而排除水分。
There is water in the ground base, which has some influence on the construction and the method of removing water. In fact, the drainage of the ground base is heated to increase the temperature of concrete and air, accelerate the rapid evaporation of water in concrete, so as to remove water.
