Abstract
The present invention relates to a kind of brightening rust removing agent, the most composed of the following components: hydrochloric acid 45 60 parts, phosphatase 24 5 parts, hexamethylenetetramine 0.4 0.6 parts, sodium lauryl sulphate 0.4 0.6 parts, triethanolamine 0.15 0.4 parts, citric acid 0.4 0.6 parts, oleic acid 0.5 1.2 parts, oxalic acid 0.8 1.6 parts, thiourea 0.5 3 parts, 3 10 parts of tartaric acid, sulfamic acid 16 parts, 20 70 parts of water.The present invention is with low cost, can use, be not likely to produce acid mist under room temperature state, the most friendly to human body and environment, and destroys minimum to sheet material, simple to operate.
Description
Technical field
The present invention relates to a kind of rust remover, a kind of brightening rust removing agent.
Background technology
Along with steel and iron industry and the manufacturing development of iron and steel, the corrosion problem of steel becomes increasingly conspicuous, the whole world every year due to
The weight of corrosion and the metal material scrapped and equipment is about the 20%-30% of metal annual production, and up to 1 × 108 More than t.Right
Before metallic article takes various anti-corrosion measure, rust cleaning is necessary processing step.Current derusting method predominantly organic tool method, change
The big class of method two.Mechanical Method is that shortcoming is that labor intensity is big, efficiency is low, dust pollution by manually striking shovel, polishing and blasting treatment
Seriously, and being limited by Components Shape, the rust of limit, corner angle, re-entrant angle and capillary inside diameter is difficult to clean off totally.Chemical method has effect
The best, the series of advantages such as efficiency is high, and technological operation is simple, low cost, are the developing direction of current rust remover.But chemical method is also
There is the danger of " hydrogen embrittlement ", contaminated air, after rust cleaning, workpiece need to be cleaned multiple times, and integrated treatment to be made the most also can
Get rusty, have a strong impact on the adhesive force of follow-up coating, especially prominent to skin of paint.Derusting method uses impregnated mostly, uses this
The method of kind, first needs to build huge immersion trough, and construction investment is very big, also has the most more seriously giving up after changing tank liquor
Liquid processes.Therefore, current chemical method is difficult to requiring higher sector application, especially the shipbuilding etc. to outsize workpiece rust cleaning
Industry.So needing a kind of brightening rust removing agent badly to solve the problems referred to above.
Summary of the invention
Not enough for above-mentioned prior art, the present invention provides a kind of brightening rust removing agent.
A kind of brightening rust removing agent that the present invention provides is achieved through the following technical solutions:
A kind of brightening rust removing agent, it is characterised in that the most composed of the following components: hydrochloric acid 45-60 part, phosphatase 24-5 parts, six
Methenamine 0.4-0.6 part, sodium lauryl sulphate 0.4-0.6 part, triethanolamine 0.15-0.4 part, citric acid 0.4-0.6
Part, oleic acid 0.5-1.2 part, oxalic acid 0.8-1.6 part, thiourea 0.5-3 part, tartaric acid 3-10 part, sulfamic acid 1-6 part, water 20-70
Part.
The invention has the beneficial effects as follows: with low cost, can use under room temperature state, be not likely to produce acid mist, to human body and
Environment is the most friendly, and destroys minimum to sheet material, simple to operate；Use the hydrochloric acid of high concentration, the speed that eliminates rust can be accelerated, improve raw
Producing efficiency, on the other hand, rust cleaning speed speeds the corrosion that the most relatively slow down workpiece, and the addition of phosphoric acid can be effectively in complex solution
Bivalence and ferric ion, extend solution service life；Restrainer plays association by compounding to itself and hexamethylenetetramine
Same-action；The addition of corrosion inhibiter neither affects the removing of article surface oxide, can effectively protect again product matrix few rotten
Erosion, reduces the hydrogen embrittlement harm to product；The complexed surfactant chosen can be dissolved in acid solution, contributes to dispersion and the rusty scale of greasy dirt
Come off, also function to suppress acid mist effect；The addition of oleic acid can slow down the corrosion of workpiece.
