Abstract
The invention relates to a bluing solution and a method for processing a steel part by using the bluing solution. The bluing solution is formed by mixing the following components by weight part: 50-60 parts of sodium hydroxide, 3-5 parts of sodium nitrite and 100 parts of deionized water. The method comprises the following treating steps: 1) de-oiling; 2) copper-removing; 3) bluing; and 4) soaking in oil. The bluing solution provided by the invention has the advantages that the boiling point for use is low, the processing time is short, the energy resource is effectively saved, the economic benefit is increased, the color of the steel part after being blued is uniform, the steel part is effectively prevented from being rusted and the appearance is beautiful.
Description
Technical field
The present invention relates to a kind for the treatment of solution and process the method for iron and steel parts with the treatment solution that turns blue of turning blue.
Background technology
It is to prevent one of important process technology that iron and steel parts gets rusty in the routine use process that iron and steel parts carries out alkaline oxygenated processing, make in all trades and professions such as machinery, in the industry of Aeronautics and Astronautics, communications and transportation, a large amount of manpower and materials of in use getting rusty and losing owing to iron and steel parts, bring immeasurable loss to Economic development, the processing of must turning blue of the standard amount breach of some component such as firearms, reaching opaque purpose, and play decoration function.There are a lot of defectives in the existing treatment solution that turns blue, and the temperature that needs when specifically being to use is high, and the time of processing is long, big energy-consuming, and use cost is high, and the iron and steel parts irregular colour after processing is even, not attractive in appearance.
Summary of the invention
For the defective that exists in the prior art, the object of the present invention is to provide a kind of use boiling point low, effectively the treatment solution that turns blue of save energy.
For reaching above purpose, the technical scheme that the present invention takes is:
A kind for the treatment of solution that turns blue, mixed by the composition of following weight part and to form:
Sodium hydroxide 50-60 part
Sodium Nitrite 3-5 part
Deionized water: 100 parts
A kind of utilization treatment solution that turns blue process to be processed the method for iron and steel parts, and concrete steps are as follows:
1) processing of deoiling
Part is put into the oil removing groove processing to be pulled out in 5 minutes.
2) go copper to process
Iron and steel parts is soaked in the pickle solution that contains chromic anhydride 300g/L, sulfuric acid 30g/L, and soak time is 10 minutes.
3) processing of turning blue
Will be through step 1) and 2) iron and steel parts be placed in the treatment solution that turns blue temperature in drying: 110 ℃-130 ℃, the time: 15-20min;
4) immersion oil
To enter synthetic spindle oil through the iron and steel parts that step 3) is processed.
The treatment solution that turns blue of the present invention uses boiling point low, and the treatment time is short, and effectively save energy promotes economic benefit, and the iron and steel parts color even after the processing of turning blue, and effectively prevents from getting rusty good looking appearance.
