环氧地坪施工前的清理案例

发布日期:2019-06-24 浏览次数:24

环氧地坪施工前的处理:1.用专用打磨机(配合手动打磨机)对涂刷区域进行整体打磨,对坑洞、缝隙、裂纹部位,保证和提高地坪漆涂层的附着力:经过处理的混凝土基面可以让地坪漆底漆更多的渗透到混凝土表面,对于整个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。

Pre-construction treatment of epoxy flooring: 1. Use special grinder (with manual grinder) to grind the painting area as a whole, to ensure and improve the adhesion of the floor paint coating on the pits, crevices and cracks. The treated concrete base surface can let the floor paint primer penetrate more into the concrete surface, for the whole. The service life of floor paint coating plays a key role. 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. Create the appropriate surface roughness: The adhesion of the floor paint coating to the concrete surface mainly depends on the mutual attraction between the 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 the roughness, the surface area will increase significantly. The gravity of the coating and the base surface on the unit area will also increase exponentially. At the same time, the suitable surface shape of the coating on the floor is provided for the adhesion of the coating, the mechanical teeth interaction is increased, and the surface area of the epoxy floor will also increase. Lacquer coatings are very good for adhesion.

3.针对新水泥地面,采用无尘喷砂机进行喷砂处理,以保证涂层的附着力。

3. For the new cement ground, dust-free sand blasting machine is used for sand blasting treatment to ensure the adhesion of the coating.

4.柱脚、墙角全部采用圆弧处理。

4. The column foot and corner are all treated by circular arc.

5.对于局部的潮湿地面,先用煤气喷枪或用碘钨灯(太阳灯)进行烘烤,以使水分达到涂装要求。

5. For local wet ground, first use gas spray gun or iodine tungsten lamp (solar lamp) to bake, in order to make the water meet the coating requirements.
