Embodiment 1

[0022] A method for derusting iron handicrafts, comprising the following steps:

[0023] (1) Degrease: Add sodium bicarbonate and sodium hydroxide to the water, heat to 55°C and cook for 6 minutes, immerse the rusty crafts in the solution and cook for 18 minutes, then add hydrochloric acid solution to neutralize the solution to pH7.0-7.5, then Add 7.2% of its mass degreasing agent to the water, heat to 73°C and boil for 27 minutes, and get the degreasing handicraft after cooling;

[0024] (2) High-temperature derusting: add water to carbon black powder and stir to make carbon black viscous liquid, use a paint brush to paint a layer of carbon black viscous liquid on the degreasing handicraft, and place it at 44°C for semi-drying Dry, then immerse in the yellow mud mixture for 2.5 minutes, take it out and place it in a high-temperature furnace for processing. The temperature of the high-temperature furnace is 217°C, the temperature rise rate is 13°C / min, and the heating time is ...

Embodiment 2

[0038] A method for derusting iron handicrafts, comprising the following steps:

[0039] (1) Degrease: Add sodium bicarbonate and sodium hydroxide to the water, heat to 57°C and cook for 7 minutes, immerse the rusty handicraft in the solution and cook for 19 minutes, then add hydrochloric acid solution to neutralize the solution to pH7.0-7.5, Then add a degreasing agent with a mass of 8.5% to the water, heat it to 75°C and boil for 29 minutes, and get a degreasing handicraft after cooling;

[0040] (2) High-temperature derusting: add water to carbon black powder and stir to make carbon black viscous liquid, use a paint brush to paint a layer of carbon black viscous liquid on the degreasing handicraft, and place it at 46°C for semi-drying dry, then immerse in the yellow mud mixture for 3 minutes, take it out and place it in a high-temperature furnace for processing. To 34°C, the cooling rate is 8°C / min; after cooling, brush the surface of the handicraft, and then paint the car...

Abstract

The invention discloses a method for removing rust on an iron craftwork. The method for removing the rust on the iron craftwork is characterized by comprising the following steps that (1) grease is removed, specifically, sodium bicarbonate, sodium hydroxide and a degreasing agent are added into water, and grease removing is conducted on the surface of the craftwork; (2) rust is removed at a high temperature, specifically, a black carbon viscous fluid coating and a yellow mud mixture coating are used on the craftwork, and the craftwork is placed at the high temperature and treated; (3) dipping is conducted, specifically, the iron craftwork is dipped into functional liquid to be subjected to dipping treatment and dipped repeatedly for 2-3 times; and (4) solidification is conducted, specifically, the dipped craftwork is placed under a 470-510 lux infrared lamp to be subjected to solidification treatment, and the treated iron craftwork is prepared. The method for removing the rust on the iron craftwork is high in rust removal rate of the iron craftwork, and cannot cause other damage to the craftwork, the oxidation resistance property of the iron craftwork after being treated can be improved greatly, and the appearance appreciation is good.
