Abstract
The invention discloses a descaling agent and a preparation method thereof. The descaling agent comprises the following components in parts by weight: 50-70 parts of sulfuric acid, 20-40 parts of naphthalic acid, 25-65 parts of N-ethylethanolamine, 80-110 parts of water, 15-35 parts of sorbitan mono-oleic acid ester, 40-80 parts of methyl isobutyl ketone, 45-65 parts of 3-phenyl propionaldehyde, and 3-9 parts of auxiliaries. The preparation method comprises the following steps: all the components are uniformly stirred; sorbitan mono-oleic acid ester, auxiliaries and 3-phenyl propionaldehyde are added in sequence for uniform mixing; and finally, methyl isobutyl ketone is added. The descaling agent is strong in descaling capacity, and can quickly remove rust scales.
Description
Technical field
The present invention relates to a kind of scale remover and preparation method thereof.
Background technology
Often can use descaling and rust-proof agent in daily life with in industrial production, namely by scale removal and antirust for the purpose of the pharmaceutical chemicals that uses or reagent.Traditional chemical rust removing uses strong acid usually, acid can with iron rust and metal oxide generation chemical reaction, generate solubility salt, thus reach the object of rust cleaning, while rust cleaning, acid to react releasing hydrogen with underlying metal again, the oxide skin of Hydrogen Energy to iron rust and indissoluble produces pressure, be conducive to their reduction with high price iron of peeling off, accelerate the process of pickling, but traditional acid solution treatment process also also exists obvious defect: namely in treating processes, the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, cause the mechanical properties decrease of metal, affect the intensity of iron and steel itself, easily form acid mist simultaneously, affect the health of operator and corrode equipment around and environment, the consumption of acid solution is also comparatively large, increases processing cost, this kind of acid can form excessive erosion to steel.In addition a large amount of residue produced, need often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.
Summary of the invention
The object of this invention is to provide a kind of scale remover and preparation method thereof, remove rust deposite ability strong, the scale removal time is short.
The present invention is by the following technical solutions:
Scale remover, comprises the component of following parts by weight: 50 ~ 70 parts, sulfuric acid, naphthalic acid 20 ~ 40 parts, N-ehtylethanolamine 25 ~ 65 parts, 80 ~ 110 parts, water, sorbitan mono-oleic acid ester 15 ~ 35 parts, methyl iso-butyl ketone (MIBK) 40 ~ 80 parts, 3-phenylpropionaldehyde 45 ~ 65 parts, auxiliary agent 3 ~ 9 parts.
As preferably, scale remover, comprises the component of following parts by weight: 60 parts, sulfuric acid, naphthalic acid 30 parts, N-ehtylethanolamine 45 parts, 95 parts, water, sorbitan mono-oleic acid ester 25 parts, methyl iso-butyl ketone (MIBK) 60 parts, 3-phenylpropionaldehyde 55 parts, auxiliary agent 6 parts.
As preferably, the mass concentration of sulfuric acid is 95 ~ 98%.
As preferably, auxiliary agent is fatty alcohol ethylene epoxide ether or polyoxyethylene oleic acid ester.
The preparation method of scale remover, comprises the following steps: sulfuric acid, naphthalic acid, N-ehtylethanolamine, water are stirred, and adds sorbitan mono-oleic acid ester, auxiliary agent, 3-phenylpropionaldehyde successively, mixes, finally add methyl iso-butyl ketone (MIBK).
beneficial effect
The scale removal time of the present invention is short, and only 13 ~ 16min just can remove rust deposite, and the scale remover clean-up time not adding sorbitan mono-oleic acid ester obviously extends, and illustrates that the present invention removes rust deposite ability strong, can remove rust deposite very soon.
