Description
Technical field
The present invention relates to a kind of Stainless Steel Cleaner, belong to the acid-washed metal material technology.
Background technology
At present, existing production field is directly to use inorganic acid to implement to clean through multiple working procedure to the black oxidation skin on stainless steel product surface and dirt impurity etc.The strong acid clean-out system of this prior art, it is long to exist cleaning process flow, and hand labor intensity is big, because the clean process has smog to produce, has three waste discharge, and environment and human body are had harm, and the field personnel easily suffers from deficiencies such as occupational illness.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of cleaning simple and easy, and hand labor intensity is lower, cleans on-the-spot non smoke and produces and three waste discharge, and the Stainless Steel Cleaner that cleaning efficiency is high is to overcome the deficiency of prior art.
The present invention solves it and wants the conception of technical solution problem to be, adopts acid, basic salt, tensio-active agent, auxiliary agent, stablizer and water etc., and is synthetic through stirring reaction at normal temperatures.Seeking effectively to reduce preparation cost, and bring into play the complementary synergism of its each component property, clean, between saving of work and time, improve cleaning performance, save low consumption, reduce and clean cost, original intention of the present invention such as safety and environmental protection to realize normal temperature.
The present invention is for above-mentioned conception, and at stainless steel clean technology, carries out exploratory development, through test practice for many years, correctly selects its component, and progressively improves its proportioning, preferably solves it and wants the technical scheme of technical solution problem to be:
A kind of Stainless Steel Cleaner, it is by acid, basic salt, tensio-active agent, auxiliary agent, stablizer and water, and the stirring reaction synthetic is characterized in that under normal temperature condition, and the component in every 1L finished product clean-out system and the weight content of each component are:
Yellow soda ash 80～120g;
Tripoly phosphate sodium STPP 40～60g;
Tartrate 20～25g;
Citric acid 10～15g;
Hydrofluoric acid 25～30g;
Nitric acid 65～100g;
Phosphatase 11 00～150g;
JFC 20～40g；
OP-10 0.1～0.5g；
Trolamine 0.5～5g;
Urotropine 0.1～0.5g;
Tertiary sodium phosphate 10～20g;
Acetic acid 3～5g;
Ethanol 5～10g;
Water surplus.
Why the present invention adopts said components, is to be familiar with by the repetition test practice.This be because: described nitric acid, phosphoric acid and hydrofluoric acid are mineral acid, all have the effect that sour solvency power is strong, cleaning speed is fast and effective, and especially high density nitric acid is to some metals, not only do not corrode and passivation arranged.And described phosphoric acid can generate the insoluble phosphate protective membrane with the workpiece reaction, plays the passivation protection effect; Described hydrofluoric acid has very strong cleansing power to metal oxide such as ferric oxide dirt, silicon dirt etc. at normal temperatures.And described citric acid, tartrate and acetic acid, all be the weak acid that does not contain harmful chlorion, little to workpiece corrosion, be the indispensable component of cleaning solution, they all are the sequestrant or the complexing agent of metal ion, play the effect of quickening rust cleaning and prolonging the cleaning solution usage period.Described basic salt yellow soda ash, tertiary sodium phosphate and tripoly phosphate sodium STPP are clean-out system basic salts commonly used, and wherein yellow soda ash is the fabulous carrier of tensio-active agent; Tertiary sodium phosphate has dispersion and wetting action, has surfactivity effect preferably, and little to the human body stimulation, and washing performance is good; Tripoly phosphate sodium STPP has good complex performance to inorganic metal ion, belongs to the sequestrant of metal ion.Tensio-active agent OP-10 alkylphenol polyoxyethylene has good wetting emulsifying effect, is nonionic surface active agent; And JFC Fatty Alcohol(C12-C14 and C12-C18) ethylene oxide condensate has the infiltration of quickening acid oxidant, accelerates the effect of cleaning speed, and has the mist effect of pressing down simultaneously.Described ethanol is a kind of stablizer.In sour cleaning process,, and strengthen the stability and the pickling ability of clean-out system because oxidation of ethanol becomes acetate.Described auxiliary agent urotropine is a promotor, and trolamine is an inhibiter, although its add-on is very little, just because both existence, and has effectively improved the activity of clean-out system, has strengthened clenaing effect, and can prevent burning, the protective money metal surface.Prototype test of the present invention proves, more than given component and the weight content of each component be best, they have good performance complement synergistic function.。
Certain component of the present invention is not limited thereto.For example: the mineral acid that is added also can be sulfuric acid, hydrochloric acid or amidosulphuric acid etc.The organic acid that is added also can be oxalic acid, oxyacetic acid, ethylenediamine tetraacetic acid (EDTA), polyacrylic acid, gather crow comes acid and quadrol methylene radical phosphoric acid etc.The basic salt that is added also can be a sodium hydroxide etc.The tensio-active agent that is added also can be a TX-10 polyoxyethylene octyl phenolic ether etc.The auxiliary agent that is added also can be other auxiliary agent with same performance.
For higher stainless steels of metal element content such as chromium, tungsten, manganese, nickel, cadmiums, in order further to improve its cleaning performance and to shorten scavenging period, the present invention also advocates to add hydrochloric acid 30～60g and/or sulfuric acid 50～70g.
Component and prepared the present invention of each composition weight content as previously discussed, its pH value is in 1～3 scope, and solid content is in 16～18% scopes, and the relative density in the time of 10～40 ℃ is in 1.2～1.3 scopes, and zero pour is-20 ℃, is white transparent liquid.
