Beschreibung
Zusammenfassung:	The invention discloses a phosphatization film sealing fluid which is an aqueous solution comprising sodium silicate, a complexing agent and an additive. A component formula of the sealing fluid is as follows: 1-30g/L sodium silicate, 0.5-10g/L complexing agent, 0.5-10g/L additive, and the balance of water. The phosphatization film sealing fluid is environment-friendly, nontoxic, simple in composition and easy to control; and after a phosphatized part is sealed by the sealing fluid, the corrosion resistance of a phosphatization film is improved greatly.
