Abstract
The invention discloses a safe on-line descaling abluent, which comprises the following parts: 5.0-90.0w% chelating agent, 0.0-1.0w% inhibitor, 1.0-30.0w% macromolecular polymer, 0.0-20.0w% sodium hydroxide and 5.0-80.0w% water, wherein the chelating agent one of hydroxy-ethidene diphosphoric acid, amino methylene triphosphate and EDTMPS; the inhibitor is benzotriazole; the macromolecular polymer is polyacrylic acid or polymaleic anhydride with molecular weight at 10000-30000; the whole raw materials are dissolved in the water to stir evenly during preparation. The product is canary and transparent liquid, it is insipid. The product can descale quickly and has inhibiting effect. After cleaning, it is unnecessary to wash, neutralize and special passivate, it can be directly put into use, therefore, the whole cleaning procedure is very simple.
Description
Technical field:
The present invention relates to main is the detergent composition technical field of base-material with the on-surface-active compound, belongs to the combination of water-soluble cpds, contains organic phospho acid, and oxyhydroxide.Also relate to the benzotriazole that the heterocycle condensed with carbocyclic ring that contains three nitrogen-atoms forms simultaneously; And polymeric acrylic acid.
Background technology:
Current chemical cleaning cleans, adopt inorganic acid class chemical substance as cleaning medium, there is bigger corrodibility in its cleaning process to being cleaned equipment, pipeline, and cleaning accidents such as spot corrosion, leakage, perforation easily take place, and the cleaning of tiny pipeline, complex pipeline is very easily caused stopping up.In case sounding stops up, aftertreatment is difficulty very.In addition, aspect safety and environmental protection, also there are a lot of drawbacks in this class agent for cleaning and scale-removing.Produce gases such as a large amount of hydrogen, hydrogen sulfide and sulfurous gas in the cleaning process.Exist and poison, fire danger.The casualty accident that causes owing to this class matting occurs repeatedly.Existing cleaning process, technology relative complex relate to the foundation, scale removal process, N-process, passivating process of water flushing, leak test, the recycle system, multiple working procedure such as flushing process for several times.Adopt the equipment pipeline after this agent for cleaning and scale-removing cleans,, and have very big potential safety hazard owing to the big corrodibility of agent for cleaning and scale-removing to metal material.Not only in cleaning process equipment pipeline matrix is had bigger corrosion, after cleaning, hydrogen ion and acid ion that absorption remains in equipment pipeline surface also can continue metallic matrix is caused corrosion.Be difficult to flushing thoroughly because be adsorbed on these harmful ions of metal base surface, it is unavoidable having residual.The drawback that needs a kind of new cleaning agent and technology to eliminate current conventional clean scale remover makes cleaning process to equipment, personal security, effective, easy to operate, the simple cleaning agent of cleaning process.
Summary of the invention:
Defective at prior art exists the purpose of this invention is to provide a kind of contaminant removing cleaning agent, and not only the scale removal cleaning performance is good, efficient is high, and to equipment, personal security, cleaning process is simple and easy to operate.
The basic design of technical scheme of the present invention is to utilize specific sequestrant and selected polymkeric substance polymer to make up, and finishes the removing of incrustation scale and rust deposite.The concrete composition of contaminant removing cleaning agent and prescription (w%) are:
Intercalating agent 5.0～90.0
Inhibiter 0.0～1.0
High molecular polymer 1.0～30.0
Sodium hydroxide 0.0～20.0
Water 5.0～80.0
Wherein said: intercalating agent is a kind of among 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, amino methane tri methylene phosphonic acid, the EDTMPS (quadrol tetramethyl subunit Alendronate); Inhibiter is a benzotriazole; High molecular polymer is polyacrylic acid or polymaleic anhydride, and its molecular weight is 10000～30000.Be that raw material is all soluble in water during preparation, stirring gets final product.Product is light yellow transparent liquid, and is tasteless.
In practice process, following prescription effect is very good:
(1)
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 5.0～90.0
Benzotriazole 0.2～1.0
Polyacrylic acid 2.0～20.0
Water 7.0～80.0
(2)
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 5.0～90.0
Benzotriazole 0.2～1.0
Sodium hydroxide 2.0～20.0
Polymaleic anhydride 2.0～20.0
Water 5.0～80.0
(3)
Amino methane tri methylene phosphonic acid 5.0～90.0
