    引起环氧地坪漆基面含水量过高原因包括什么?

    目前要求绝大部分建筑的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地坪面层失效。

    At present, the floor paint system for most buildings requires DPM. The waterproof layer is usually formed by covering the ground base with polyethylene waterproof material or asphalt waterproof material. Wet through the assembly leads to hydrostatic pressure, such as ground water that leaking out of the base surface. A floor system with a waterproof membrane or sink or drainage pipe will not occur. But we also need to be aware that if only drainage pipes are available, but there is no waterproof floor system, we need to conduct a basement moisture test, combined with other relevant factors to consider, such as groundwater level. Serious hydrostatic pressure even leads to failure of floor surface.

    许多树脂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地坪系统在涂装完成后,牢固度大受影响,从而引起地坪面层起泡、分层,甚至失效。

    Many resin flooring systems can not be used on high water content substrates. Therefore, if this kind of floor paint material is reused, the bottom coating will be damped before completion, and it is likely that the whole floor system will be greatly affected by the firmness after finishing the coating, which will cause the floor layer to bubble, stratify and even lose. Effect.

    一般来说,只有出现以下几种情况,才会导致基面含水量过高:

    Generally speaking, only the following situations can lead to excessive water content on the base surface.

    1、未配备防水层的现代建筑

    1. Modern building 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 types of buildings, such as warehouses or logistics centers, do not have floor systems themselves, so there is no waterproof layer. But once it is converted to other functional buildings, the problem of excessive moisture content will emerge.

    2、基面完工时间短或未干透

    2, the completion time of the base surface is short or dry.

    大量的实践证明,基面完工后让其自然风干的效果最佳,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 natural air drying after the completion of the base is the best, otherwise it will probably lead to a variety of problems in the floor system after completion. But modern construction speed often can not consume a lot of time, so the use of resin as a surface coating method 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 due to improper coating, or coating during the waterproof layer was damaged, such as pierced by steel bars.
