Description
Technical field
The present invention relates to a kind of anti-incrustation corrosion inhibitor, particularly a kind of high-efficiency composite scale corrosion inhibitor.
Background technology
The Scale inhibitors being applied the earliest in water treatment approximately will be calculated polymeric phosphate.Polymeric phosphate, except having scale effect, also has corrosion inhibition concurrently.But its shortcoming is facile hydrolysis is orthophosphoric acid salt, if control improperly, can make original not too serious calcium carbonate scale problem change very serious calcium phosphate scale problem into.The appearance of the organic phosphoric acid sixties in 20th century (salt) Scale inhibitors, shows that in water, the mitigation and antiscaling technology of calcium carbonate has been obtained breakthrough progress.Also make the ultralow chromium treatment formulations of recirculated cooling water be applied.This ultralow chromium formula uses within the scope of the pH of 7.5-8.5 value.The utilization of high pH value makes the requirement of the chromate amount for inhibition be down to 5-10mg/L from the 15-25mg/L of traditional chromium-phosphorus-zinc formula, has greatly alleviated the disadvantageous effect to environment.Why can do like this, be because the application of organic phospho acid (salt) Scale inhibitors, makes to cause dirty salt calcium carbonate in water and obtain in the cathodic area of metallic surface the deposition of control.This controlledly calcium carbonate of deposition, has played the effect of cathodic corrosion inhibitor.
The application of organic phospho acid (salt) Scale inhibitors, also making this phosphorus of recirculated cooling water poly-phosphate-organic phospho acid (salt)-polyacrylic acid (salt) is that basic treatment formula is used widely.But in existing composite water conditioner, due to the unsuitable composite effect of creating antagonism of each component, cause effect to reduce or the phenomenon lost happens occasionally, the increasing to such an extent as to cost of the consumption of water body medicament inferior increases obviously.And for water bodys inferior such as calcium sulfate scale and barium sulfate scale, calcium magnesium silicate, ironic hydroxide dirt, zinc hydroxide dirts, also there is no so specific Scale inhibitors in addition at present, due to medicament long-term storage, run into the unfavorable factors such as oxygen, moisture, each component interaction, the drug effect of composite water conditioner can be scattered and disappeared gradually.
Summary of the invention
The object of the invention is to provide a kind of high-efficiency composite scale corrosion inhibitor, become assignment system unreasonable to solve existing anti-incrustation corrosion inhibitor, wide spectrum, water body reagent cost inferior do not increase obviously, to the water body poor effect inferior such as calcium magnesium silicate, ironic hydroxide dirt, zinc hydroxide dirt, calcium sulfate scale and barium sulfate scale, the technical problem such as should not put for a long time.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of high-efficiency composite scale corrosion inhibitor, and this anti-incrustation corrosion inhibitor is mainly made up of following compositions in weight percentage:
10～15 parts of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, 10～15 parts of sodium lignosulfonates, 3～5 parts of benzotriazoles, 2～5 parts of methylsulfonic acids, 5～8 parts of poly-epoxy succinic acids, 6～9 parts of sodium wolframates, 2～5 parts of thiocarbamides, 7～12 parts, tensio-active agent, 30～40 parts of deionized waters.
As preferably, described tensio-active agent is one or several mixtures of octadecyl amine hydrochlorate, dioctadecylamine hydrochloride, stearyl dimethyl benzyl ammonium chloride, palmityl trimethyl ammonium chloride, dodecyl dimethyl phenyl bromo-phosphonium.
In the present invention's formula, on its structural unit of sodium lignosulfonate, contain phenolic hydroxyl group and carboxyl, can generate insoluble protein complex, be used for controlling suspended substance and iron dirt, there is dispersive ability.Being a kind of dispersion agent and integrated agent, is also a kind of inhibiter.In circulating water treatment agent, utilize the complexing action of this product and zinc, the zinc in water is laid in, a certain amount of zine ion can be constantly provided, suppress the corrosion of water system.
Benzotriazole can stabilizing water quality, suppress the corrosion of water system.
Acid restrainer thiocarbamide, reduces the corrosion of acid system to porcelain, stainless steel, metallic surface greatly, is conducive to keeping device crust, can make cleaned any surface finish as newly.
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid is a kind of organophosphorus acids anti-incrustation corrosion inhibitor, can form stable complex compound with the many kinds of metal ions such as iron, copper, zinc, oxide compound that can dissolution of metals surface.1-Hydroxy Ethylidene-1,1-Diphosphonic Acid still can play good corrosion-mitigation scale-inhibition effect at 250 DEG C, still very stable under high pH value, and not facile hydrolysis is difficult for decomposing under general light and heat condition.Resistance to acids and bases, resistance to oxychlorination performance are good compared with other organic phosphoric acid (salt).1-Hydroxy Ethylidene-1,1-Diphosphonic Acid can belong to ion with underwater gold, especially calcium ion forms six annulus inner complexs, thereby the good scale inhibition effect of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid tool the obvious threshold effect of tool, when with the scope of the invention in the compound use such as benzotriazole, poly-epoxy succinic acid, sodium wolframate time, show desirable synergistic effect.
Even if tensio-active agent is a class also remarkable material of reduction table (boundary) surface tension in the time of very low concentrations.Along with going deep into of Surfactant research, it is generally acknowledged at present if under low concentration the remarkable material of change table (boundary) surface properties or character related to this, that derive from thus, can incorporate tensio-active agent category into.No matter which kind of tensio-active agent, its molecular structure forms by two portions.One end of molecule is the hydrophobic group of non-utmost point oleophylic, sometimes also referred to as oleophilic group; The other end of molecule is the hydrophilic hydrophilic group of polarity, sometimes also referred to as lipophobic group or be called visually hydrophilic head.Two class formations divide the two ends in same molecule and are connected with chemical bond with the diametrically opposite molecular fragment of performance or group, form a kind of structure of asymmetric, polarity, thereby given not only hydrophilic, but also oleophylic of such particular molecule, not again just the characteristic of the hydrophilic or oleophylic of entirety.This peculiar structure of tensio-active agent is referred to as " amphiphilic structure " (amphiphilic structure) conventionally, surfactant molecule thereby be also often known as " parents' molecule ".What the present invention adopted is cats product.
The each component of the present invention performance synergy, has scale inhibition, inhibition lasting medicine, efficient, stable chemical nature, not facile hydrolysis etc., the low feature of cost in water.It is better to water body effects inferior such as calcium magnesium silicate, ironic hydroxide dirt, zinc hydroxide dirt, calcium sulfate scale and barium sulfate scales, be applicable to Different Waters scale inhibitor.This invention is applied in the water system such as boiler, pipeline, and its Heat stability is good even still keeps good dispersing property at 250 DEG C, and scale inhibition, corrosion inhibition are good.And in poor-quality water, disperse hydrous oxide and organic dirt etc. also very effective.Can effectively prevent the formation of incrustation scale, the sticky body of microorganism, thereby the good scale inhibition effect of tool the obvious threshold effect of tool.
