≪ Surface treatment system 1 for rust prevention >

Referring to Fig. 1, in the surface treatment system 10 of the object P, the pre-treatment unit 11 can perform a pre-treatment on the object P to be treated. This is to remove oil, rust, scale, etc., which are on the metal material prior to coating. That is, the deaeration processing unit 111 can remove the oil of the object P by using a solvent or the like.

The immersion processing unit 112 can immerse and immobilize the object P on the surface of the object P and simultaneously perform primary washing. It is preferable that the temperature of the immersion bath for immersing the object P is within the range of 30 占 폚 to 35 占 폚.
