Abstract
The invention relates to a rust remover for steel precise components and a rust removing technology. The rust remover is composed of the following compositions in percent by weight: 15% of chromic anhydride, 15-17% of phosphoric acid, 1-1.2% of sulfuric acid and 66.8-69% of water. The rust removing technology comprises: immersing a steel precise component subjected to cleaning and oil removing into a solution of the rust remover, heating to 80-90 DEG for about 30-40 min; taking out and flushing with tap water for 1 min, and then immersing in a sodium carbonate aqueous solution with a concentration of 0.5% for about 5 min; taking out and immersing in a passivating solution composed of a sodium nitrite aqueous solution with a concentration of 10% and a sodium carbonate aqueous solution with a concentration of 0.5% according to a ratio of 50%:50%, heating to 80-90 DEG C for about 5-10 min; and taking the steel precise component out from the passivating solution, and flushing with tap water, wiping to dry and sealing with oil. The beneficial effects comprise that the technology is simple, and the rust remover has no any influence on dimension, shape, surface glossiness and precision on the steel precise component, and is good in ruse removing effect.
Description
Technical field
The present invention relates to a kind of steel precision part rust remover and derusting process.
Background technology
Steel precision part is in moist and very easy corrosion in atmospheric environment, in order to solve or mitigate corrosion, at present industrial common employing chemical process rust cleaning, most of chemical rust removing method can be removed corrosion, but steel precision part surface is impacted, affect gloss and the precision on steel precision part surface.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide that a kind of technique is simple, effects on surface gloss, precision has no effect, steel precision part rust remover and the derusting process that eliminates rust effective.
The technical solution used in the present invention: a kind of steel precision part rust remover and derusting process, is characterized in that: described rust remover is grouped into by following one-tenth by weight percentage: chromic anhydride 15%, phosphatase 11 5～17%, sulfuric acid 1～1.2%, water 66.8～69%; Above-mentioned each composition is proportionally weighed respectively, add successively, stir.
Derusting process comprises the steps:
(1), steel precision part is cleaned to oil removing with gasoline or acetone.
(2), immerse in the rust remover solution of making by above weight percent composition cleaning the steel precision part of oil removing, be heated to 80～90 ℃, approximately 30～40min.
(3), steel precision part is taken out and rinses 1min with tap water at once from rust remover solution, then immerse about 5min in 0.5% aqueous sodium carbonate.
(4), steel precision part is taken out from aqueous sodium carbonate, immerse in the passivating solution being formed by 0.5% aqueous sodium carbonate of 50% 10% nitrous acid acid sodium aqueous solution and 50%, be heated to 80～90 ℃, approximately 5～10min.
(5), steel precision part is taken out from passivating solution with tap water rinse, dry, oil sealing.
