It is being 44.5 by mass ratio：25.5：17.6：13.5 sodium hydroxide, tertiary sodium phosphate, sodium metasilicate, sodium carbonate and sulphur
Oil removing again is carried out in the degreasing fluid of sour 5 kinds of basic species compositions of sodium；
(6) washing and drying
Auto parts are washed in current water to metalwork, water speed is 1.5-2.5m/s, when a length of 10-
Auto parts are carried out drying and processing by 15min after cleaning.
It is preferred that, the composition of step (1) the emulsion degreasing agent includes kerosene, turpentine oil, laurate, triethanolamine, fourth
Base cellosolve, surfactant and the sodium metasilicate aqueous solution, the mass ratio of its each component is 61:22.5:5.4:3.6:1.5:
2.4:6.7。
It is preferred that, increase white picking and secondary washing after step (3) washing.
It is preferred that, the white picking technique is：Mass ratio is used for 3：1 concentrated nitric acid, the nitration mixture of hydrofluoric acid, to automobile
Part carries out pickling, and the time is 8s.
It is preferred that, the secondary washing process is：Auto parts are washed in current water, water speed is 0.3m/
After cleaning processing is dried in auto parts by s.
It is preferred that, the method for alkali liquor oil removing uses infusion process in the step (5), and auto parts are put into alkali lye, plus
Heat alkali liquid keeps boiling 5min to carry out oil removing to boiling.
Beneficial effect：The invention provides a kind of oil removing cleaning procedure of auto parts, using a variety of deoiling methods to vapour
Car part carries out depth removal operation so that auto parts surface is brighter and cleaner, facilitates the surface treatment of auto parts subsequently,
Prevent auto parts from causing surface treatment to come off due to the oil of surface residual, step (1) the emulsion degreasing agent into
Dividing includes kerosene, turpentine oil, laurate, triethanolamine, butyl cellosolve, surfactant and the sodium metasilicate aqueous solution, and its is each
The mass ratio of component is 61:22.5:5.4:3.6:1.5:2.4:6.7, the degreasing agent reacts little to humidity, at ambient temperature
It can be carried out, be characterized in nontoxic, therefore can accomplish environmental protection, the step when carrying out oil removing to auto parts
(3) increase white picking and secondary washing after washing, the technique can increase the effect of pickling degreasing, institute by secondary processes
Stating white picking technique is：Mass ratio is used for 3：Auto parts are carried out pickling, time by 1 concentrated nitric acid, the nitration mixture of hydrofluoric acid
For 8s, two kinds of compositions can play targetedly oil removing effect to the part of steel, and hydrofluoric acid can be carried out with steel components
Reaction, the oil on surface of going out, and concentrated nitric acid can form diaphragm in steel components surface passivation in piece surface, so
Degreasing can either be removed, again part can be protected not corroded too, the secondary washing process is：To vapour in current water
Car part is washed, and water speed is 0.3m/s, and auto parts are dried into processing after cleaning, and circulating water can be by piece surface
Acid solution take away, be easy to the method for alkali liquor oil removing in follow-up processing, the step (5) to use infusion process, auto parts put
Enter in alkali lye, heating alkali lye keeps boiling 5min to carry out oil removing to boiling.By the technique can neutralize acid solution while,
The greasy dirt on thorough auto parts surface of going out.
