The calcium sulfate scale cleaning agent provided by the invention is high in removal rate, safe and environment-friendly, and has excellent application prospects.

Description

Calcium sulfate scale washing agent and preparation method thereof
Technical field
The present invention relates to the industrial cleaning agent technical field, relate more specifically to a kind of calcium sulfate scale washing agent of cleaning the GGH heat exchanger tube and preparation method thereof that is specially adapted to.
Background technology
It is a great problem that cleans industry at present both at home and abroad that industry is cleaned, and wherein relates generally to dissolving and the removing of multiple indissoluble dirts such as calcium sulfate, Calucium Silicate powder, ferric oxide, with the amount maximum of calcium sulfate, also the most difficult in these indissoluble dirts.Traditional purging method is to carry out earlier carrying out the pickling proceed step by step after soda boiling makes the transition, and its subject matter is that descaling rate is low, cleans not thorough; Some researchs of adopting thionamic acid or EDTA to clean are also arranged, but its be applied to the GGH interchanger clean in the time, heating and constitute clean cycle loop difficulty, this equipment is only applicable to the spray Cleaning for High Capacity mode, Special Circumstances can be fit to adopt the dismounting soaking and washing.Also can thoroughly not solve the clean-out system of GGH indissoluble dirt at present on the domestic and international market.
Summary of the invention
For overcoming the problems referred to above of the prior art, the invention provides a kind of calcium sulfate scale washing agent and preparation method thereof, this clean-out system descaling rate height uses and makes all more conveniently, has a good application prospect.
The technical solution used in the present invention is: a kind of calcium sulfate scale washing agent, gross weight with the calcium sulfate scale washing agent is benchmark, its component by following percentage composition is mixed and is got: the main lotion of 20-30%, the washing assistant of 10-20%, the buffer reagent of 1-2.5%, the permeate agent of 1-2.5%, the stripper of 1-1.5% and the water of 43.5-67%; Wherein, main lotion is selected from one or more in sodium acetate, Sodium salts humic acids, B,EDTA, sodium glycolate, sodium polyphosphate, the thionamic acid sodium; Washing assistant is selected from one or more in Amino Trimethylene Phosphonic Acid sodium, hydroxy ethylene diphosphonic acid sodium, ethylene diamine tetra methylene phosphonic acid sodium, hexanediamine tetramethyl fork sodium phosphate, the poly (sodium aspartate).
Further, above-mentioned buffer reagent is selected from one or more in vulkacit H, ammonium citrate, ethylenediamine tetraacetic acid (EDTA), the sodium polyacrylate.
Further, above-mentioned permeate agent is selected from one or more in alkyl alcohol Soxylat A 25-7, alkylphenol polyoxyethylene, polyoxyethylene glycol, the petroleum sodium sulfonate.
Preferably, above-mentioned stripper is selected from chlorination dodecyl trimethyl ammonium, chlorination-1, one or more in 3-dialkyl group pyridine, methylacryoyloxyethyl ammonium chloride, dodecyl benzyl dimethyl ammonium chloride, the two octadecyl ammonium chloride of dimethyl.
According to a further aspect in the invention, also provide a kind of preparation method of calcium sulfate scale washing agent, it comprises above-mentioned each component is mixed and dissolving, obtains the step of calcium sulfate scale washing agent.Namely, to be that the component of the following percentage composition of benchmark is fully mixed and dissolved the main lotion that makes calcium sulfate scale washing agent: 20-30% with the gross weight of calcium sulfate scale washing agent, the washing assistant of 10-20%, the buffer reagent of 1-2.5%, the permeate agent of 1-2.5%, the stripper of 1-1.5% and the water of 43.5-67%; Wherein the concrete selection of each composition as mentioned above.
Each component materials among the present invention can directly be buied from commercial channels.And wherein employed water is for accounting for the water of gross weight 43.5-67% under 20-50 ℃ temperature.
Compared with prior art, the present invention has following advantage: the invention provides a kind of calcium sulfate scale washing agent and preparation method thereof, this calcium sulfate scale washing agent is specially adapted to clean the calcium sulfate dirt that produces in the GGH interchanger, it is slow to have solved in the prior art calcium sulfate dirt dissolution rate, clean halfway problem, this calcium sulfate scale washing agent can effectively solve the technical barrier that exists in GGH interchanger normal temperature spray or the soaking and washing.Certainly, this clean-out system also is applicable to the calcium sulfate dirt that other environment of cleaning produce, and to calcium sulfate dirt clearance rate height, cleaning operation is convenient, and preparation is simple, and safety and environmental protection can be widely used in the dirty cleaning of calcium sulfate field.
