Description
Technical field
The present invention relates to field of mechanical technique, and in particular to a kind of to be suitable for suitable for the rust remover and one kind of steel precision component
The derusting process of the rust remover of steel precision component.
Background technology
Metal material is placed under outdoor or open-air condition and gets rusty easily, and not only influences presentation quality, can also influence to paint, glue
Being normally carried out for technique such as connect, such as handle not in time, can more cause scrapping for material, cause unnecessary economic loss.
Traditional chemical derusting can be chemically reacted usually using strong acid, acid with iron rust and metal oxide, and generation can
Dissolubility salt, so as to achieve the purpose that derusting, while derusting, acid again can and underlying metal react and release hydrogen, Hydrogen Energy pair
The oxide skin of iron rust and indissoluble produces pressure, be conducive to they peeling and high price iron reduction, accelerate the process of pickling.But pass
The acid solution processing method of system there is also it is obvious the defects of：The generation of a large amount of hydrogen can make steel produce hydrogen embrittlement i.e. in processing procedure
Phenomenon, causes the mechanical properties decrease of metal, influences the intensity of steel in itself；Acid mist is easily formed at the same time, influences operating personnel's
Equipment and environment around health and corrosion；The consumption of acid solution is also larger, increases processing cost；This kind of acid can be formed steel
Excessive erosion.In addition the residue largely produced, need to often discharge, not only heavy corrosion industrial pipeline, but also contaminated soil and environment.
Due to the processing technology of metal material and the difference of component, it is impossible to derusting of the exploitation suitable for all metal materials
Agent.
The content of the invention
Problem to be solved by this invention is to provide a kind of strong derusting ability, room temperature cleaning, to component corrosion and environment dirt
Contaminate the small rust remover and its derusting process suitable for steel precision component.
To achieve these goals, the technical solution taken of the present invention is：A kind of rust remover suitable for steel precision component
It is made of the raw material of following mass percent：
Chromic anhydride 10-20%,
Sulfuric acid 0.8-1.5%,
Phosphatase 11 3-18%,
Water 60.5-76.2%.
Preferably, the rust remover is made of the raw material of following mass percent：
Chromic anhydride 18%,
Sulfuric acid 1%,
Phosphatase 11 5%,
Water 66%.
A kind of derusting process suitable for steel precision component, includes the following steps：
(1) by part acetone oil removing；
(2) parts after oil removing in step (1) are immersed in rust removing solution, it is 5- to be heated to 75-95 DEG C of heating time
15min；
(3) parts 3min is rinsed with tap water；
(4) part immerses in the aqueous sodium carbonate of 0.3-0.8% and soaks 4-8min：
(5) part is immersed in passivating solution, is heated to 75-95 DEG C, heating time 5-15min；
(6) rinsed, dried with tap water, oil sealing.
Preferably, 10% sodium nitrite in aqueous solution and the 0.5% of 50% that passivating solution component is 50% in the step (5)
Aqueous sodium carbonate.
Beneficial effects of the present invention：The present invention by by chromic anhydride, sulfuric acid, phosphoric acid and water by quality proportioning be mixed with and
Into, the rust remover derusting ability prepared is strong and environmental pollution is small, suitable for the derusting of steel precision component, preparation of the invention
Technological parameter is simple in method and preparation efficiency is high.
Embodiment
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, with reference to
Embodiment, the present invention is further explained.
Embodiment 1：
A kind of rust remover suitable for steel precision component is made of the raw material of following mass percent：
