引起环氧地坪漆基面含水量過高原因包括什麼？

目前要求絕大部分建築的环氧地坪漆系統需要具備防水層(DPM)。防水層一般是通過在地面基層上/下鋪蓋聚乙烯防水材料或者瀝青防水材料來形成的。潮濕度過大會導致流體靜壓作用，比如地下水會滲出基面等。一般具備防水膜或者水槽或排水管道的环氧地坪系統是不會出現這種情況的。但是我們也要註意，如果僅具備排水管道，但沒有防水層的地坪系統，我們需要進行基面水分測試，並結合其他相關因素進行考慮，比如說地下水位等。嚴重的流體靜壓作用甚至對導致地坪面層失效。
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.

許多樹脂地坪系統無法在高含水量的基面上使用，因此，如果再使用這種地坪漆材料會使得底塗層在完工前出現受潮現象，而且很可能導致整個地坪系統在塗裝完成後，牢固度大受影響，從而引起地坪面層起泡、分層，甚至失效。
Many resin flooring systems can not be used on high water content substra透水地坪tes. 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.
一般來說，隻有出現以下幾種情況，才會導致基面含水量過高：
Generally speaking, only the following situations can lead to excessive water content o彩色沥清地坪n the base surface.
1、未配備防水層的現代建築
1. Modern building without waterproof layer
有些建築類型，比如倉庫或者物流中心等，本身並沒有實施地坪系統，所以也沒有防水層。但是一旦將其改建為其他功能的建築，那麼含水量過高的問題就會顯現。
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、基面完工時間短或未幹透
2, the completion time of the base surface is short or dry.
大量的實踐證明，基面完工後讓其自然風幹的效果最佳，否則很可能會導致完工後地坪系統出現各種問題。但是現代化的建造速度往往無法耗費大量工時，所以使用樹脂材料作面塗層的方式越來越流行。
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、防水層失效
3. Failure of waterproof layer.
防水層可能會出現失效的情況，雖然導致其失效的原因有很多種，但是通常來說都是由於塗裝不正確，或者塗裝期間防水層被損壞，比如被鋼筋刺穿等。
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.
