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. 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, 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, 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.
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.
