停車場环氧地坪出現泛堿的原因及應對方法

在停車場施工环氧地坪固然可以解決地面灰塵問題，然而現在一些停車場环氧地坪工程出現瞭泛堿問題。泛堿主要是指环氧地坪表面出現像“水印”一樣的斑塊，一般來說這種現象居多是出現瞭潮濕陰涼的天氣，而如果泛堿現象嚴重，即斑塊面積比較大，那麼將會嚴重影響地坪美觀度。那麼我們來瞭解停車場地坪出現泛堿的原因以及如何應對。
The construction of epoxy floors in parking lots can solve the problem of dust on the ground, but now some parking lot floors have the problem of flooding alkali. Pan-alkaline mainly refers to the surface of the floor appears like a "watermarking" like patches, generally speaking, this phenomenon is mostly a wet and cool weather, and if pan-alkaline phenomenon is serious, that is, the patch area is relatively large, then it will seriously affect the beauty of the floor. Then we will understand the reasons for the emergence of the car park floor and how to deal with it.

Parking lot floor
停車場地坪出現泛堿的原因：
The reasons for the presence of soda in the parking lot are:
1、 混凝土基材的含水率高於8%，地面堿性較大。
1, the moisture content of concrete substrate is higher than 8%, and the surface alkalinity is larger.
2、 刷塗完底漆沒有很好的封閉，基材中仍有可溶性鹽例如，水泥、石灰等。
2. The primer is not well sealed after brushing. Soluble salts such as cement and lime still exist in the substrate.
3、 膩子層所選的膩子耐水性不好，堿性太強，且膩子層未幹就進行施工。
3, putty layer selected putty water resistance is not good, alkaline is too strong, and putty layer is not dry for construction.
4、 使用不合格的环透水地坪氧地坪漆材料。
4, use unqualified epoxy floor paint material.
停車場地坪出現泛堿應對方法：
The way to deal with parking lots is alkaline.
1、施工前要檢查基層是否符合規范要求，包括含水率等，並且等基面幹透才施工。
1. Before construction, check whether the base meets the requirements of the code, including water content, etc., and construct the base surface with dry penetration.
2、選擇底漆要性能較好，耐堿性和封閉性都要好的地坪底漆。並對基層要做好封閉處理。
2, choose primer to better performance, alkali resistance and sealing are better floor primers. And the grass-roots must be closed.
3、使用具有高強度、抗滲的彈性膩子。
3, use high strength, 印花地坪impermeability of elastic putty.
