Problems solved by technology
[0002] Steel can be seen everywhere in our daily life. Because it is often exposed to wind and rain, it is easy to rust. Rust on steel will greatly affect its quality of use and cause safety hazards.
Now the more common anti-rust method is to paint the surface of the steel, but this method cannot achieve the effect of curing the root cause.

Embodiment Construction
[0014] The following describes the embodiments of the present invention in detail.
[0015] A method for antirust treatment of steel surfaces, characterized in that it comprises the following steps:
[0016] a. Remove slag and remove impurities on the surface of steel;
[0017] b. Cleaning, clean the workpiece with 10-20MPa, and dry it in a dryer at 120-170°C;
[0018] c. Soak in anti-rust oil, use anti-rust oil composition: potassium permanganate 10-16g / L, sodium nitrate 16-20g / L, zinc nitrate 15-20g / L, zinc oxide 20-25g / L, sulfuric acid 12 -15ml / L, hydrogen peroxide 30-35mL / L, and the rest soaked in water;
[0019] d. Wash, wash with warm water at 50-70°C for 40-60 minutes, and dry in a drier at 120-170°C.
[0020] In step c, the conditions are a temperature of 30-50° C., a pH value of 2.5-3.0, and a soaking time of 1-2 hours.
[0021] The steel surface antirust treatment method of the invention has simple procedure and convenient operation, and can greatly improve the a...

The invention provides a rust prevention treatment method for a steel surface. The method comprises steps as follows: a, slag removing: impurities on the steel surface are removed; b, cleaning: a workpiece is cleaned under the pressure of 10-20 MPa and dried by a dryer at the temperature ranging from 120 DEG C to 170 DEG C; c, immersion in rust-preventative oil: the rust-preventative oil comprises 10-16 g / L of potassium permanganate, 16-20 g / L of sodium nitrate, 15-20g / L of zinc nitrate, 20-25 g / L of zinc oxide, 12-15 ml / L of sulfuric acid, 30-35 mL / L of hydrogen peroxide and the balance of water, and the workpiece is immersed in the rust-preventative oil; d, cleaning: the workpiece is cleaned with warm water for 40-60 min at the temperature ranging from 50 DEG C to 70 DEG C and dried by the dryer at the temperature ranging from 120 DEG C to 170 DEC C. According to the rust prevention treatment method for the steel surface, the procedure is simple, the operation is convenient, and the rust prevention capability of the steel can be greatly improved while compared with that of steel coated with paint for rust prevention with a traditional method.
