a. before leaving work every day, adding an oil-water separation additive into a cleaning tank according to 0.1-0.5 wt% of tank liquor, adding the oil-water separation additive for 3 times, adding one third of the oil-water separation additive every time, and circulating the tank liquor for more than 5 minutes by using a circulating pump;
b. after staying overnight, taking out the floating oil separated from the surface of the bath solution when working the next day, and then continuously cleaning;
c. the cleaning agent in the tank liquor is normally supplemented according to the process;
d. the groove changing period can be prolonged to 6-10 times of the original period.
Compared with the prior art, the invention has the beneficial effects that:
the invention uses the cationic surfactant as an oil-water separating agent, uses the oxygen-containing solvent as an oil-water separating auxiliary agent, and the two components are matched with each other, so that the purpose of oil-water separation can be achieved, the service life of the cleaning agent is prolonged, the tank replacement is reduced, the discharge is reduced, and the wastewater treatment cost is reduced; but also can achieve the purpose of sterilization and anti-corruption; and the cleaning effect, the rust prevention and other additional functions of the cleaning agent are not influenced. Time and labor are saved, the cost is low, sewage treatment and discharge are reduced, and the effects of energy conservation and emission reduction are achieved.
The oil-water separation additive can reduce the discharge of waste water, reduce the use amount of the cleaning agent and reduce the use cost of the cleaning agent.
In addition, when the cleaning solution is not used for a long time, the cleaning solution is likely to be deteriorated and emit peculiar smell, and the oil-water separation additive product is a strong bactericide and can keep the bath solution from being deteriorated and emitting peculiar smell.
