In the construction of epoxy flooring, there is oil pollution on the surface, but it is still on the top of the construction, which will cause great damage to the quality of the epoxy flooring in the later period. Then, how to deal with the oil pollution on the construction ground of Jinan epoxy floor? There are several methods to deal with the oil pollution on the construction ground of Jinan epoxy floor:
1。 Flushing with hydrochloric acid
Flushing with hydrochloric acid mainly plays a role in degreasing.
The concentration of hydrochloric acid should not be too high, up to 4-5%.
For some places where oil pollution is more serious, it can be pushed several times.
When using this method, we must pay attention to the safety and ventilation work。 If it is spilled by hydrochloric acid carelessly, it needs to be washed with plenty of clean water immediately。
2. Alkali Washing of Ground
花开棋牌This is the simplest and oldest method, which is widely used because of its low price.
花开棋牌A kilogram of caustic soda is mixed with 20 kilograms of water and scraped on the ground to neutralize hydrochloric acid on the ground.

Organic solvent degreasing is a common degreasing method with high efficiency, suitable for all kinds of oil contamination, and generally does not affect the physical properties of the base surface。
However, inorganic salts and alkaline substances can not be removed at the same time, and oil removal is not complete.
Solvent volatilization is dangerous to fire and poisoning。 Therefore, the organic solvents used are required to have strong solubility, unsuitable for ignition, low toxicity and slow volatilization。
The commonly used cleaning solvents include dilute materials, gasoline, petroleum solvents, turpentine, toluene, diphenyl and chlorine-containing solvents.

Manual wiping: dipping in alkali or organic solvents for wiping, time-consuming, low efficiency; but no need, low cost, flexible operation。
Flame: By using a blowtorch, heat it to 300-400 C, make the oil pollution burn into carbide, remove the oil thoroughly, but it will cause certain pollution to the environment, damage the ground, and may have the existence of residual carbon.
Jinan epoxy floor construction ground oil pollution how to do? Although the removal of oil pollution is only a small part of the epoxy floor construction process, but to get a high-quality epoxy floor can not ignore any details of the construction.
