    环氧地坪施工针对不同基础地面的处理方法

    环氧地坪漆施工前需要对基础地面进行处理,主要目的有以下两点:1、保证和提高环氧地坪漆涂层的附着力:经过处理的混凝土基面可以让环氧地坪漆底漆更多的渗透到混凝土表面,对于整个环氧地坪漆涂层的使用寿命有着关键的作用。尤其是基面存在油污、水时,由于油、水与涂料的相容性差,难以形成连续的涂层,即使形成了完整涂层,其涂层附着力也会大大降低,使涂层过早脱落。当表面有灰尘不经过基面护理直接施工时,轻者使地坪漆涂层产生麻点,重的可能导致地坪漆涂层的大面积脱落,缩短地坪漆使用寿命。因此,同时为建立一个光滑、平整、美观的涂层做好必要的准备,为整个地坪漆工程创造良好的基础。

    Before the construction of epoxy floor paint, it is necessary to treat the foundation ground. The main purposes are as follows: 1. Ensuring and improving the adhesion of the floor paint coating: the treated concrete base can make the epoxy floor paint penetrate more into the concrete surface, which plays a key role in the service life of the whole floor paint coating. Especially when there is oil and water on the base surface, it is difficult to form a continuous coating because of the poor compatibility of oil, water and paint. Even if a complete coating is formed, the adhesion of the coating will be greatly reduced and the coating will fall off prematurely. When there is dust on the surface and it is not directly constructed without base care, the lighter one causes pitting in the floor paint coating, and the heavier one may cause large area peeling off of the floor paint coating and shorten the service life of the floor paint. Therefore, at the same time, it is necessary to prepare a smooth, smooth and beautiful coating and create a good foundation for the whole floor paint project. 

    2、创造合适的表面粗糙度:地坪漆涂层附着在混凝土表面主要是依靠地坪漆中的极性分子与底材表面分子间的相互引力。混凝土在经过地坪研磨机研磨处理后,会使表面变粗糙,随着粗糙度增大,表面积也显著增加,单位面积上的涂层与基面的引力也成倍增大,同时还为地坪漆涂层附着提供了合适的表面形状,增加了机械齿合作用,对环氧地坪漆涂层附着十分有利。

    2. Creating the appropriate surface roughness: The adhesion of the floor paint coating to the concrete surface mainly depends on the mutual attraction between polar molecules in the floor paint and the surface molecules of the substrate. The surface of concrete will become rough after grinding by floor grinder. With the increase of roughness, the surface area will increase significantly, and the attraction between the coating and the base surface will increase exponentially. At the same time, it provides a suitable surface shape for the adhesion of the floor paint coating and increases the mechanical teeth interaction, which is very beneficial to the adhesion of the epoxy floor paint coating.
