Description
Technical field
The present invention relates to water treatment agent fields, and in particular, to a kind of malic acid composite slow-corrosion scale resistor composition and apple
Tartaric acid composite slow-corrosion scale resistor and its application.
Background technique
The scale inhibition processing of industry water has always been concerned with that it is convenient to carry out scale inhibition processing by water treatment agents such as antisludging agents
And it is efficient.
Phosphorous water treatment agent is gradually replaced by " green scale corrosion inhibitor " due to causing the eutrophication of water quality, even
It is considered the nontoxic low-phosphorous organic water treatment agent of phosphine carboxylic acid (salt) type, also decomposes and be positive due to the complexity of water body itself at last
Phosphate, so as to cause the eutrophication of water body.In the early 1990s, the U.S. laboratory Betz has developed poly-epoxy succinic acid
Class antisludging agent has good effect to calcium carbonate scale, environmentally protective, has a wide range of application, but its single structure of functional groups limit
The dispersibility to iron is made, not significant to the effect of the dirty matter such as calcium phosphate, calcium sulfate, corrosion inhibition is also general.
Environmentally protective corrosion inhibiting and descaling agent undoubtedly has become the developing direction of water treatment agent, many existing no-phosphate corrosion resistances
Although dirty agent appreciates the importance of environmental protection, but still remain self-defect.
The Southeast China University symbol goddess in the moon etc. have synthesized the macromolecular list with polyethyleneoxy long-chain by sulfonating agent of sulfamic acid
Body polyether sulfonate (APES) is that aqueous monomer phase has synthesized block copolymer with APES and acrylic acid (AA), which is nothing
Phosphorus antisludging agent, to the scale inhibition performance of calcium phosphate up to 92%；The researcher is using ammonium persulfate as initiator, with acrylic acid and allyl
Nonyl phenol polyethers ammonium sulfate is that monomer has synthesized TS-10/AA polymer antisludging agent, and calcium phosphate scale inhibition performance is up to 99.3%；It is insufficient
Place is that two kinds of antisludging agents are nitrogenous and sulphur, and its effect for hindering calcium carbonate scale has no research.
Then the symbol goddess in the moon etc. are also with allyl polyglycol monoether, monoxone, sodium hydroxide, maleic anhydride etc. for raw material system
For a kind of novel non-phosphate nitrogen-free antisludging agent maleic anhydride/allyl polyglycol carboxylic acid sodium, resistance calcium phosphate scale rate is reachable
99%, but the effect of this antisludging agent of one resistance calcium carbonate scale is unknown, and the two maleic anhydride monomer has certain toxicity, can be to ring
Border causes damages, and also will affect scale inhibition effect.
Jiangsu University's Qiu Feng celestial being etc. is modified maleic anhydride (MA) using beta-cyclodextrin (β-CD), prepares maleate
Change beta-cyclodextrin (β-CD-MA), then is prepared for without phosphorus with sodium p styrene sulfonate (SSS) monomer using ammonium persulfate as initiator
Antisludging agent β-CD-MA-SSS, calcium carbonate scale inhibition rate are up to 99.9%, but the antisludging agent is in addition to the toxicity of maleic anhydride, in structure
Also contain sulphur, has certain harm to environment.
Nanjing Normal University's this grade of Yang Wei is received with acrylic acid and allyl polyglycol carboxylic acid and has synthesized a kind of nothing for monomer
Acrylic acid of the phosphorus nitrogen-free without sulphur/allyl polyglycol carboxylic acid is received antisludging agent (AA/APEC), and discovery AA/APEC has good
The performance of calcium sulfate scale is hindered, but the effect for hindering calcium carbonate and calcium phosphate scale has no research.
University Of Tianjin is permitted to know, and intelligent equal using itaconic acid, hydroxypropyl acrylate and sodium allylsulfonate as raw material to be prepared for itaconic acid more
Membered copolymer research of non-phosphorus scale inhibitor, which uses in units such as Zibo power plant Nan Ding, Gaoqing steam power plants, but itaconic acid valence
Lattice are relatively high, and sulfur-bearing in the antisludging agent structure, to the scale inhibition performance of calcium carbonate only 60% or so.
It is multiple that Chinese invention patent application CN1850661A discloses a kind of environmental type for circulating water cooling treatment
Corrosion inhibiting and descaling agent is closed, the invention is by according to epoxy sodium succinate, poly (sodium aspartate), hydrolysis of polymaleic anhydride, sodium gluconate, zinc
The dirt dispersion agents such as salt and corrosion inhibiter compound in proportion, have the characteristics that without phosphorus, biodegradable, but this antisludging agent structure
In it is nitrogenous, poly-epoxy succinic acid and hydrolyzed polymaleic anhydride are general to resistance calcium phosphate scale effect, and maleic anhydride monomer has one
Determine toxicity.
Chinese invention patent application CN102417242A discloses a kind of environment-friendly type composite corrosion-inhibiting for recirculated cooling water
Antisludging agent is compounded in proportion by poly-epoxy succinic acid, poly-aspartate, benzotriazole, sodium gluconate and sodium tungstate,
Equally have the characteristics that outside defect without phosphorus, biodegradable but nitrogenous in removing structure and that resistance calcium phosphate scale is ineffective, day
The price of aspartic acid valuableness and the toxicity of sodium tungstate will also hinder its application.
Chinese invention patent application CN102225809A discloses a kind of ascorbic acid phosphate-free corrosion inhibition antisludging agent and preparation side
Method, the corrosion inhibiting and descaling agent by hydrolyzed polymaleic anhydride, acrylic ternary copolymer, ascorbic acid, sulfamic acid compound, zinc salt,
Gluconate and distilled water are combined, and resistance calcium carbonate scale rate may be up to 98% or more, and the chemicals treatment cost of water per ton is not
0.12 yuan of foot, but contain sulphur, nitrogen in this corrosion inhibiting and descaling agent structure, hydrolyzed polymaleic anhydride is undesirable to the scale inhibition effect of calcium phosphate.
Chinese invention patent application CN101235145A discloses a kind of glycine/aspartic acid as green scale inhibitor
The preparation method of copolymer, gained copolymer are 72% or so to the scale inhibition performance of calcium carbonate in tap water, and shortcoming is as resistance
It is nitrogenous in the copolymer of dirty agent and at high cost, preparation method is complicated.
Summary of the invention
