Abstract
The present invention is a kind of infusion process rust cleaning agent prescription and derusting method, and pickling agent prescription is industrial sulphuric acid 10 20%, technical hydrochloric acid 15 35%, sodium chloride 40 70%, KC corrosion inhibiter 0.5 1.2%.Mordant is diluted with clear water, 3 are soaked during the metallic article for needing rust cleaning dirty is put into the mordant aqueous solution, and in the solution that submerges, pull metallic article out, cleaned with clear water, metallic article is immersed after being soaked in sodium hydroxide solution, first cleaned with cold water, the cleaning of reusable heat water.
Description
Technical field
The invention belongs to metal coating technology field, and in particular to a kind of infusion process rust cleaning agent prescription and rust cleaning side
Method.
Background technology
Conventional metal-derusting mainly has hand cleaning method and mechanical derusting method, and hand cleaning method is that one kind is simplest to be removed
Rust method.With scraper, hand hammer, steel brush, emery cloth（Paper）, the instrument such as emery wheel, struck, shoveled, being ground, being scraped etc. that to remove rust dirty.This visit
The advantage asked is simple and easy to apply, low cost；Have the disadvantage that labour intensity big, inefficiency, quality be unstable, work situation is poor.
Mechanical derusting method is a kind of relatively more extensive derusting method of current application, and its principle is effectively removed using impact and rubbing action
Fall corrosion and its dirt.The conventional instrument of this method has hand held, electric emery wheel, powered brush, pneumatic brush, pistol for rust removal etc..The method
Advantage be derusting, efficiency all higher, but have the disadvantage that these instruments also need to artificial operation, labour intensity is larger, to several
What complex-shaped and precision component is less applicable, the need for being also not suitable for extensive rust cleaning.
The content of the invention
The technical problems to be solved by the invention are directed to the deficiencies in the prior art, there is provided a kind of new rust cleaning agent prescription and
Derusting method.
The technical problems to be solved by the invention are realized by following technical scheme.Pickling agent prescription is industry
Sulfuric acid 10-20%, technical hydrochloric acid 15-35%, sodium chloride 40-70%, KC corrosion inhibiter 0.5-1.2%.Mordant is diluted with clear water,
The metallic article for needing rust cleaning dirty is put into the mordant aqueous solution, and soaks 3 in the solution that submerges, and pulls metallic article out, uses clear water
Cleaning, metallic article is immersed after being soaked in sodium hydroxide solution, is first cleaned with cold water, the cleaning of reusable heat water.
Compared with prior art, the present invention is chemically reacted using acid solution with the rust dirt for being cleaned metal surface, is allowed to
It is dissolved in acid solution, the hydrogen that acid is produced with metal function in addition makes oxide skin mechanical detachment again.
Specific embodiment
1st, pickling agent prescription.Industrial sulphuric acid 13%, technical hydrochloric acid 20%, sodium chloride 66%, KC corrosion inhibiter 1%.
The 2nd, mordant clear water is diluted to 5% aqueous solution, it is water-soluble that the metallic article for needing rust cleaning dirty is put into mordant
In liquid, and in the solution that submerges, regulation water temperature is soaked 30 minutes to 35 DEG C.
3rd, pull metallic article out, cleaned with clear water 3 times.
4th, metallic article is immersed in 2% sodium hydroxide solution, soak time 30 minutes.
5th, pull metallic article out, cleaned with cold water 2 times, then cleaned 2 times with 90 DEG C of hot water.
Claims (5)
1. infusion process rust cleaning agent prescription and derusting method, it is characterised in that metallic article is cleaned with through pickling, clear water, alkali cleaning, cool
Water cleaning, hot water cleaning.
2. infusion process according to claim 1 rust cleaning agent prescription and derusting method, it is characterised in that：The pickling formula of liquid
It is industrial sulphuric acid 10-20%, technical hydrochloric acid 15-35%, sodium chloride 40-70%, KC corrosion inhibiter 0.5-1.2%.
3. according to claim 1 or claim 2 infusion process rust cleaning agent prescription and derusting method, it is characterised in that：Institute
It is that, by the solution immersion that metallic article concentration is 1-10%, soaking temperature is 15-50 DEG C, 10-60 points of immersion to state the pickling
Clock.
4. infusion process according to claim 1 rust cleaning agent prescription and derusting method, it is characterised in that：The alkali cleaning, be by
Metallic article is soaked 10-60 minutes with the sodium hydroxide solution of 1-6%.
5. infusion process according to claim 1 rust cleaning agent prescription and derusting method, it is characterised in that：The hot water is cleaned
Cleaned 1-5 times with 80-100 DEG C of hot water.
