Abstract
The invention discloses a reverse osmosis membrane scale inhibitor and a preparation method thereof. The scale inhibitor is prepared from polyepoxysuccinic acid, amino trimethylene phosphonic acid, diethylenetriamine pentaacetic acid pentasodium salt, hexadecyl tributyl phosphonium bromide, distilled water, dodecyl triphenyl phosphonium bromide, methoxymethyl triphenyl phosphonium bromide, 1, 2-benzisothiazolin-3-one, hydroxyethylidene-1,1-diphosphonic acid, polyacrylic acid and benzotriazole. The usage amount of the scale inhibitor is less and is only 1 to 5 mg/L; the effect is lasting, i.e., after the scale inhibitor is placed for one month at 60 to 80 DEG C, the scale inhibiting ratio is 96 to 100 percent; the reverse osmosis membrane scale inhibitor has a good sterilizing effect and positive effects in improving calcium scale resistance and iron dispersing property.
Description
Technical field
The application belongs to environmental protection reagent process field, particularly relates to a kind of environmental protection, reverse osmosis membrane antisludging agent that corrosion inhibition is good and preparation method thereof.
Background technology
Antisludging agent (scaleinhibitor): be the slightly solubility inorganic salts had in energy disperse water, prevention or the precipitation of interference slightly solubility inorganic salts in metal surface, fouling function, and maintain the class medicament that hardware has good heat-transfer effect.Cold exchange device antiseptic corrosion inhibitor is with epoxy resin and specific amino resin for base-material, and it is formulated to add the appropriate various auxiliary agent such as various antirust, anticorrosion, is one pack system.It has excellent shielding, impervious, rustless property, good scale inhibition, thermal conductivity, the performances such as excellent weak acid resistant, highly basic, organic solvent, its strong adhesion, and rete is bright, pliable and tough, fine and close, hard.
The result of peptizaiton stops into dirt interparticlely contact with each other and condense, thus can stop the growth of dirt.Becoming dirty particle can be calcium, magnesium ion, can also be dust, silt or other water-insolubles.Dispersant is the polymer with certain relative molecular mass (or degree of polymerization), and the height of dispersive property is closely related with the size of relative molecular mass (or degree of polymerization).The degree of polymerization is too low, then few by the population of absorption dispersion, dispersion efficiency is low; The degree of polymerization is too high, then too much by the population of absorption dispersion, water body becomes muddy, even forms flco (effect is now close with flocculant).Compared with chelation, peptizaiton is efficient.In middle high hardness water, the divergent function of antisludging agent plays a major role.
Reverse osmosis membrane antisludging agent is the antisludging agent being specifically designed to counter-infiltration (RO) system, can extend the cleaning systems cycle, makes membrane lifetime extend and reduce costs, and can ensure that system is normally run according to design aquifer yield.Large, medium and small boiler stops fouling and corrosion, and chemical treatment method in useable stove, adds antiseptic corrosion inhibitor in boiler feed water, reduces boiler water hardness demineralized water, and reduce fouling and corrosion, this method is simple and practical, receives praises from customers.
Reverse osmosis antisludging agent is the antisludging agent being specifically designed to counter-infiltration (RO) system and nanofiltration (NF) and ultrafiltration (UF) system, can prevent face fouling, can improve aquifer yield and produce water quality, reducing operating cost.Effective control inorganic matter fouling in very large concentration range, do not condense with iron-aluminium oxide and silicon compound and form insoluble matter, effectively can suppress polymerization and the deposition of silicon, dense water side SiO2 concentration can reach 290, can be used for counter-infiltration CA and TFC film, NF membrane and milipore filter, splendid dissolubility and stability are all effective within the scope of 5-10 to water ph value.
Effective control calcium carbonate, calcium sulfate, strontium sulfate fouling, the LSI of calcium carbonate is up to+3.0 still unlikely foulings, for all main reverse osmosis membranes, dispersion is blocked particulate and is maintained reverse osmosis membrane surface clean, the pH scope of water still belongs in effective range from 5-9, direct interpolation or dilution use, compatible to relevant flocculant, can be used for controlling diaphragm piece-rate system fouling precipitation and reduce particles holography.Before the effect saying reverse osmosis antisludging agent, first sketch counter-infiltration system: counter-infiltration system is through fine filter by former water, seed activity carbon filter, compression charcoal filter etc., pressurizeed by pump again, utilize aperture to be 1/10000 μm and (be equivalent to 1/6000 of Escherichia coli size, viral 1/300) reverse osmosis membrane (RO film), the water of higher concentration is made to become low concentration of water, simultaneously by industrial pollutants, heavy metal, bacterium, the impurity be mixed in a large number in water such as virus are all isolated, thus reach the physical and chemical index and sanitary standard of drinking regulation, output is to clear to pure water, the optimal selection that human body supplements high-quality moisture content in time. the water degree of purity produced due to RO reverse osmosis technology is the highest in a cutting water technology of current mankind grasp, cleanliness factor almost reaches 100%.
Be applicable to the material of various film pipe, be applicable in various different water quality, still have the scale prevention ability of high effect, reduce the cleaning frequency of film pipe, the demand of acid adding can be replaced, prevent acid adding cause possible etching problem, addition is extremely low, there is splendid thresholding effect simultaneously, the scale inhibition that can obtain optimum economic benefit controls, to iron, effect that the metal ions such as manganese all have good chelating stable, prevent it from producing dirt on film pipe, product efficacy and stability are all much better than the antisludging agent of calgon or straight polymer type, reverse osmosis membrane system can be allowed to operate in higher producing water ratio.Reverse osmosis membrane is the key equipment of counter-infiltration system, and when system long-time continuous is run, in water, calcium magnesium plasma constantly can be separated out and in reverse osmosis membrane surface attachment, form fouling and clogging fenestra, can affect the water outlet efficiency of counter-infiltration system like this, damages reverse osmosis membrane.Due to reverse osmosis membrane costly, so in system cloud gray model, one section of medicine system be increased, in water, add reverse osmosis antisludging agent, delay precipitation and the face fouling of calcium ions and magnesium ions.
Reverse osmosis technology principle is under the effect higher than solution osmotic pressure, these materials and water can not be separated according to other materials through pellicle.The membrane aperture of reverse osmosis membrane is very little, therefore, it is possible to effectively remove dissolved salts, colloid, microorganism, organic matter etc. in water.System have water quality good, consume energy low, pollution-free, technique is simple, the advantage such as easy and simple to handle.And universal along with humanity concept, and the formation of novel harmonious society, designs a kind of nontoxic, odorless, environmental protection and good reverse osmosis membrane antisludging agent of corrosion inhibition and preparation method thereof is very important.
