引起环氧地坪漆基面含水量过高的原因有哪些?目前要求绝大部分建筑的无锡环氧地坪漆系统需要具备防水层(DPM)。防水层一般是通过在地面基层上/下铺盖聚乙烯防水材料或者沥青防水材料来形成的。潮湿度过大会导致流体静压作用，比如地下水会渗出基面等。一般具备防水膜或者水槽或排水管道的环氧地坪系统是不会出现这种情况的。但是我们也要注意，如果仅具备排水管道，但没有防水层的环氧地坪系统，我们需要进行基面水分测试，并结合其他相关因素进行考虑，比如说地下水位等。严重的流体静压作用甚至对导致环氧地坪面层失效。

What are the reasons for the high moisture content of epoxy floor paint? At present, most of the building epoxy floor paint systems need to have waterproof layer (DPM). Waterproofing layer is usually formed by laying polyethylene waterproofing material or asphalt waterproofing material on or under the ground base. Excessive humidity can lead to hydrostatic effects, such as groundwater seeping out of the base surface. This is not the case for epoxy flooring systems with waterproof membranes or flumes or drainage pipes. But we should also pay attention to the fact that if there are only drainage pipes but no epoxy floor system with waterproof layer, we need to test the moisture of the base surface and consider other relevant factors, such as groundwater level. Severe hydrostatic pressure may even lead to the failure of the floor surface. 许多树脂环氧地坪系统无法在高含水量的基面上使用，因此，如果再使用这种环氧地坪漆材料会使得底涂层在完工前出现受潮现象，而且很可能导致整个环氧地坪系统在涂装完成后，牢固度大受影响，从而引起环氧地坪面层起泡、分层，甚至失效。

Many resin flooring systems can not be used on high water content base surfaces. Therefore, if this epoxy flooring paint material is used again, the bottom coating will be damped before completion, and it is likely that the firmness of the whole epoxy flooring system will be greatly affected after finishing painting, which will cause foaming of the epoxy flooring surface. Layering, or even failure.

一般来说，只有出现以下几种原因，才会导致基面含水量过高：

Generally speaking, only the following reasons can lead to excessive water content in the base surface:

1、未配备防水层的现代建筑

1. Modern Buildings without Waterproof Layer

有些建筑类型，比如仓库或者物流中心等，本身并没有实施无锡环氧地坪系统，所以也没有防水层。但是一旦将其改建为其他功能的建筑，那么含水量过高的问题就会显现。

Some building types, such as warehouses or logistics centers, do not implement floor systems themselves, so there is no waterproof layer. But once it is converted into other functional buildings, the problem of excessive water content will emerge.

2、基面完工时间短或未干透

2. Short or not thoroughly dried base surface

大量的实践证明，基面完工后让其自然风干的效果更佳，否则很可能会导致完工后地坪系统出现各种问题。但是现代化的建造速度往往无法耗费大量工时，所以使用树脂材料作面涂层的方式越来越流行。

A large number of practices have proved that the effect of natural air-drying is the best after the foundation is completed, otherwise it may lead to various problems in the floor system after completion. However, modern construction speed often can not consume a lot of time, so the use of resin materials for surface coating is becoming more and more popular.

3、防水层失效

3. Failure of Waterproof Layer

防水层可能会出现失效的情况，虽然导致其失效的原因有很多种，但是通常来说都是由于涂装不正确，或者涂装期间防水层被损坏，比如被钢筋刺穿等。

Waterproof layer may fail, although there are many reasons for its failure, but usually it is due to improper painting, or the waterproof layer is damaged during painting, such as pierced by steel bars.
