Abstract
The invention discloses a rust remover suitable for a steel precision part and a rust removing process of the rust remover and relates to the technical field of machines. The dust remover is composed of, by mass, 10%-20% of chromic anhydride, 0.8%-1.5% of sulfuric acid, 13%-18% of phosphoric acid and 60.5%-76.2% of water. The rust remover is prepared by mixing the raw materials according to the mass ratio. The prepared rust remover is high in rust removing capacity, low in environmental pollution and suitable for rust removing of the steel precision part. Process parameters in a preparation method are simple, and the preparation efficiency is high.
Description
Technical field
The present invention relates to field of mechanical technique, be specifically related to a kind ofly be suitable for the rust remover of steel precision component and a kind of derusting process being suitable for the rust remover of steel precision component.
Background technology
Metallic substance gets rusty easily under being placed in outdoor or open-air condition, not only affects visual appearance, also can affect
Normally carrying out of the technique such as to spray paint, bonding, as processed not in time, more can cause scrapping of material, causing unnecessary financial loss.
Traditional chemical rust removing uses strong acid usually, acid can with iron rust and metal oxide generation chemical reaction, generate solubility salt, thus reach the object of rust cleaning, while rust cleaning, acid to react releasing hydrogen with underlying metal again, and the oxide skin of Hydrogen Energy to iron rust and indissoluble produces pressure, be conducive to their reduction with high price iron of peeling off, accelerate the process of pickling.But traditional acid solution treatment process also also exists obvious defect: namely in treating processes, the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, causes the mechanical properties decrease of metal, affects the intensity of iron and steel itself; Easily form acid mist simultaneously, affect the health of operator and corrode equipment around and environment; The consumption of acid solution is also comparatively large, increases processing cost; This kind of acid can form excessive erosion to steel.In addition a large amount of residue produced, need often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.
Due to the complete processing of metallic substance and the difference of composition, the rust remover being applicable to all metallic substance can not be developed.
Summary of the invention
Problem to be solved by this invention is to provide that a kind of ability of rust cleaning is strong, normal temperature cleaning, to component corrosion and the little rust remover being suitable for steel precision component of environmental pollution and derusting process thereof.
To achieve these goals, the technical scheme that the present invention takes is: a kind of rust remover being suitable for steel precision component is made up 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, described rust remover is made up of the raw material of following mass percent:
Chromic anhydride 18%,
Sulfuric acid 1%,
Phosphatase 11 5%,
Water 66%.
Be suitable for a derusting process for steel precision component, comprise the steps:
(1) part is used acetone oil removing;
(2) be immersed in rust removing solution by the component after oil removing in step (1), being heated to 75-95 DEG C of heat-up time is 5-15min;
(3) with tap water component 3min;
(4) part immerses in the aqueous sodium carbonate of 0.3-0.8% and soaks 4-8min;
(5) immerse in passivating solution by part, be heated to 75-95 DEG C, heat-up time is 5-15min;
(6) with tap water, dry, oil sealing.
Preferably, in described step (5), passivating solution composition is 10% sodium nitrite in aqueous solution of 50% and 0.5% aqueous sodium carbonate of 50%.
Beneficial effect of the present invention: the present invention forms by chromic anhydride, sulfuric acid, phosphoric acid and water being mixed with by quality proportioning, the rust remover rust cleaning ability prepared is strong and environmental pollution is little, be suitable for the rust cleaning of steel precision component, in preparation method of the present invention, processing parameter is simple and preparation efficiency is high.
