我们知道地面油污也是环氧地坪施工中在进行原混凝土地面处理时常遇到的问题，在施工环氧地坪的初级阶段要对地面进行很好的处理，否则地面处理不好会对后期环氧地坪的施工质量造成很大的危害。各种油污的存在严重影响环氧地坪涂层与基面的粘结力，而油类的渗透性均极强，尤其是长期接触油污的基面，油污很难清除干净，少有彻底、有效的办法就是重新浇筑混凝土基面，在完全干燥后马上施工环氧地坪。

We know that the surface oil pollution is also a common problem in the construction of epoxy flooring. In the initial stage of the construction of epoxy flooring, the ground should be treated well, otherwise the poor treatment of the ground will cause great harm to the construction quality of the later flooring. The existence of various oil contaminants seriously affects the bonding force between epoxy floor coating and the base, and the permeability of oil is very strong, especially on the base which has been exposed to oil contamination for a long time. It is difficult to clean up the oil contamination. There are few thorough and effective ways to re-pour the concrete base and construct the epoxy floor immediately after drying. 在不具备重新浇筑混凝土基面的情况下，常规来说，根据油污污染程度，主要采用以下几种方式就可以增强环氧地坪涂层与基面之间的粘结力：

In the absence of re-pouring concrete base, according to the degree of oil pollution, the bonding force between the epoxy floor coating and the base can be strengthened mainly by the following ways:

1、先用盐酸冲洗后碱洗地面。盐酸冲洗主要起到一个除油的作用。盐酸的浓度不能太高，用到4~5%即可。对于油污较重的地方，可多推洗几次。使用这个方法要注意安全、通风，如果不小心被盐酸溅到，需要用大量的水冲洗。盐酸冲洗完后用碱洗地面。使用一公斤的烧碱与20公斤的水混合，刮涂地面，目的是为了中和地面的盐酸。因为环氧环氧地坪底层不耐强盐酸。

1. First wash with hydrochloric acid and then wash the ground with alkali. Hydrochloric acid rinse plays an important role in removing oil. The concentration of hydrochloric acid should not be too high, 4~5% can be used. For heavy oil, it can be washed several times. Use this method to pay attention to safety, ventilation, if accidentally splashed by hydrochloric acid, need to use a lot of water to wash. After washing with hydrochloric acid, wash the ground with alkali. A kilogram of caustic soda is mixed with 20 kilograms of water to scrape the ground in order to neutralize the hydrochloric acid on the ground. Because the epoxy floor is not strong enough to resist hydrochloric acid.

2、火焰灼烧：此方法只针对可燃的油类有效。应注意不能过度灼烧，否则会使混凝土基面爆裂。

2, flame burning: this method is only effective for combustible oil. Attention should not be paid to excessive ignition, otherwise the base surface will burst.

3、打磨处理。只适用于薄层油污(<2mm)，使用打磨机将地面被腐蚀的水泥和油污打磨掉，然后用大量的水冲洗地面。

3, grinding treatment. It is only suitable for thin oil contamination (< 2mm). The ground is polished with corroded cement and oil contamination by a grinder, and then the ground is washed with a large amount of water.

用以上方法处理后，能有效的改善环氧地坪漆涂层与基面之间的粘结力，但是油污基面施工环氧始终不够稳定，所以必须经过几次维修、在基层油污全部清除后，脱层的情况才会慢慢消失。地面油污处理是件非常麻烦的事，建议生产中有油污外漏地面的企业及汽车修理厂等先做好环氧地坪漆后营业生产。

After the above treatment, the bonding force between the coating and the base can be effectively improved. However, the construction of epoxy on the oil-contaminated base is not stable enough, so the delamination will gradually disappear after several repairs and the removal of all the oil contamination at the base. It is a very troublesome thing to deal with the oil pollution on the ground. It is suggested that enterprises and automobile repair factories that have oil leakage on the ground should do a good job of epoxy floor paint before operating.
