Abstract
The invention discloses a neutral sulfate cleaning agent. The cleaning agent comprises the following components by weight percent: 10-15% of organic phosphoric acid, 0.5-1% of chemical cosolvent, 0.05-0.1% of nonionic surfactant, 10-12% of value regulating agent, 0.5-1% of reducing agent, and the balance of water. The preparation method of the cleaning agent comprises steps of firstly dissolving organic acid in water through directly stirring or slightly heating, then sequentially adding the cosolvent, the reducing agent and the value regulating agent, and finally, regulating the solution to be neutral to finish preparing the cleaning agent. The cleaning agent has advantages of being capable of descaling thoroughly and uniformly, being nontoxic and odorless, non-inflammable and non-explosive, having a simple preparation method and low cost, being not limited by temperature when for cleaning, and not eroding equipment as the cleaning liquid and waste liquid are neutral; after being cleaned, equipment like carbon steel and stainless steel can be directly passivated in the waste liquid by adding passivator, the passivation effect is good, and the equipment is not easy to scale. The cleaning agent simplifies the cleaning processes, has stable performance, is not easy to decompose and go bad, and can be stored for more than three years.
Description
Technical field
The present invention relates to a kind of clean-out system, be specifically related to a kind of neutral sulfatase clean-out system.
Background technology
In present industrial enterprise, usually can be because of reasons such as water quality, special process, specific installations, can cause the raw Sulfates dirt of knot in equipment, and this type of dirt utilizes traditional soda acid lotion, can not effectively remove, cleaning performance is very undesirable, and if acid cleaning can produce a large amount of hydrogen in treating processes, the generation of hydrogen can make the generation Hydrogen Brittleness Phenomenas such as steel, cause the mechanical properties decrease of metal, affect the intensity of iron and steel itself; Easily form acid mist simultaneously, affect operator's health and corrosion equipment and environment around; The consumption of acid solution is also larger, increases processing cost; This class acid can form excessive erosion to steel.In addition a large amount of residues that produce, need often discharge both heavy corrosion industrial pipelines, again contaminated soil and environment; Common alkali lye cleaning performance is bad, also large to environment, harm, and the research and development application of this reagent has solved the defect of classical acid alkali lye.
Summary of the invention
Object of the present invention is exactly the defect existing for prior art, and a kind of neutral sulfatase clean-out system is provided.Make it under neutrallty condition, can carry out swelling softening and constantly dissolving to the sulfate scale on equipment at short notice, easily come off and consoluet object to reach, and equipment zero is corroded.This cleaning agent requires green non-pollution, and technique is simple, has certain storage period, and raw material is cheaply easy to get, and consumption is few, can adapt to most of envrionment conditionss, can recycling.
Its technical scheme is: a kind of neutral sulfatase clean-out system, include machine phosphonic acid, chemical solubility promoter, nonionogenic tenside, tone pitch agent, reductive agent and water, and their weight percent is:
Weight percentages of components (%)
Organic phospho acid 10-15
Chemistry solubility promoter 0.5-1
Nonionogenic tenside 0.05-0.1
Tone pitch agent 10-12
Reductive agent 0.5-1
Water surplus
Compound method: the each weight percentages of components providing by formula, first by after direct stirring or low-grade fever are dissolved it in organic acid dissolving and water, then add successively solubility promoter, reductive agent, tone pitch agent, finally regulator solution to neutrality complete preparation.
Wherein, described organic phospho acid is the one in 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, sodium glycolate, potassium acetate.Described chemical solubility promoter is NH
4hF
2, NaF, NH
2cONH
2in one or more.Described nonionogenic tenside is fatty alcohol-polyoxyethylene ether or non-ionic polyacrylamide.
The present invention compared with prior art, has the following advantages:
1, scale removal is thorough, evenly, can not cause system slit and kapillary latch up phenomenon, after having cleaned, does not affect Chromating Film On Zn Deposits without rinsing directly adds passivating solution;
2, nontoxic, tasteless, do not fire not quick-friedly, scavenging solution pH value is 6.5-7.0, the PH that uses tone pitch agent solution easy to control when preparation is neutrality;
3, blending process is simple, and cost is low, cleans and is not subject to temperature limitation, and scavenging solution and waste liquid are neutrality, corrosion-free to equipment;
4,, to the equipment such as carbon steel and stainless steel, after cleaning, can directly in its waste liquid, add passivator to carry out passivation.Good passivation effect, equipment is less scaling.Simplify cleaning;
5, stable performance, is difficult for decomposing and goes bad, and the shelf lives can reach more than 3 years.
Embodiment
A kind of neutral sulfatase clean-out system, include machine phosphonic acid, chemical solubility promoter, nonionogenic tenside, tone pitch agent, reductive agent and water, their weight percent is: organic phospho acid 10-15%, chemical solubility promoter 0.5-1%, nonionogenic tenside 0.05-0.1%, tone pitch agent 10-12%, reductive agent 0.5-1%, surplus are water; Compound method: the each weight percentages of components providing by formula, first by after direct stirring or low-grade fever are dissolved it in organic acid dissolving and water, then add successively solubility promoter, reductive agent, tone pitch agent, finally regulator solution to neutrality complete preparation.Wherein, described organic phospho acid is the one in 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, sodium glycolate, potassium acetate.Described chemical solubility promoter is NH
4hF
2, NaF, NH
2cONH
2in one or more.Described nonionogenic tenside is fatty alcohol-polyoxyethylene ether or non-ionic polyacrylamide.
According to the weight proportion of above-mentioned raw materials, mixing and stirring, makes clean-out system clean the equipment such as carbon steel and stainless steel, reaches better effect.
