Abstract
The invention provides a water treatment corrosion inhibitor and a water treatment agent containing the same. The water treatment corrosion inhibitor is prepared from sodium silicate, sodium oleate, sodium dodecyl benzene sulfonate and hexamethylenetetramine, wherein the addition of various components in each liter of water to be processed is as follows: 0.1-2g of sodium silicate, 0.02-2g of sodium oleate, 0.1-2g of sodium dodecyl benzene sulfonate, and 0.05-2g of hexamethylenetetramine; and the water treatment agent comprises sodium humate and a corrosion inhibitor. The corrosion inhibitor disclosed by the invention is free of poison and pollution, and can be compounded with a sodium humate water treatment agent for use. The corrosion inhibitor can generate a synergistic effect together with sodium humate; the functions of the anti-scaling action, the contaminant separation, sterilization and algae removal, and corrosion inhibition are fully developed; and the sodium humate water treatment agent product is further perfected.
Description
Technical field
What the present invention relates to is a kind of preparation for water treatment.
Background technology
In the modern industry recirculating cooling water system, usually adopting traditional phosphorus is fouling and the etching problem that water conditioner comes Controlling System.But phosphorus be water conditioner easily and the Ca in water coolant
2+And Mg
2+Generate secondary incrustation scale and incrustation scale skewness in system Deng reaction; The phosphorus that exists in system provides nutrition source for fungus algae, makes the fungus algae overpreading, has produced biological clay, must use sterilant ability sterilization algae removal.The cooling waste water of system's blowdown has not only polluted environment, and easily makes body eutrophication, produces red tide.Therefore, replace the important and urgent task that the phosphorus line formulation water conditioner has become current treatment of cooling water.
Sodium salts humic acids is macromolecular compound, has the several functions such as demineralized water, antiscale, protection against corrosion and scale removal, and the Sodium salts humic acids low price, and nontoxic, chemical stability is good, can deposit for a long time use.Sodium salts humic acids is a kind of good scale remover, the scale effect mechanism of Sodium salts humic acids is not merely calcium, magnesium ion to be stabilized in water, but generated grain slag (not forming hard scale), reach scale inhibition effect by blowdown, at this moment calcium, magnesium ion concentration change a part of grain slag amount that does not generate incrustation scale that comprised, and Sodium salts humic acids also can be adsorbed on the metallic surface, prevents fouling.So Sodium salts humic acids is the inevitable requirement of industry as scale remover, but the corrosion inhibition of Sodium salts humic acids is not very desirable.Show according to the part survey data of U.S. EPRI (Electric Power Research Institute), the fault of boiler tube boiler makes equipment availability reduce by 3%.In the fault in power station, boiler failure can account for more than 70%.And in boiler failure take the explosion of economizer, superheater and water wall, leak as main.Abrasion and corrosion is the major cause of explosion, leakage.The generating set of current China is just developing into subcritical, supercritical pressure unit is not if take some countermeasures to the etching problem of heat power equipment, just unit is difficult to safe operation.
So must seek a kind of inhibiter that can be composite with Sodium salts humic acids, by this inhibiter and Sodium salts humic acids compound use, reach scale removal and inhibition double effects to carbon steel.
Summary of the invention
The object of the present invention is to provide a kind of nontoxic pollution-free, can with the water treatment corrosion inhibitors of Sodium salts humic acids generation synergistic effect.The present invention also aims to provide a kind of water conditioner that contains inhibiter.
The object of the present invention is achieved like this:
Water treatment corrosion inhibitors of the present invention is comprised of water glass, sodium oleate, Sodium dodecylbenzene sulfonate and hexamethylenetetramine, and in every liter of pending water, the add-on of each component is water glass 0.1-2g, sodium oleate 0.02-2g, Sodium dodecylbenzene sulfonate 0.1-2g, hexamethylenetetramine 0.05-2g.
The water conditioner that contains inhibiter of the present invention comprises Sodium salts humic acids and inhibiter, described inhibiter is comprised of water glass, sodium oleate, Sodium dodecylbenzene sulfonate and hexamethylenetetramine, in every liter of pending water, the add-on of each component is Sodium salts humic acids 0.025g, water glass 0.1-2g, sodium oleate 0.02-2g, Sodium dodecylbenzene sulfonate 0.1-2g, hexamethylenetetramine 0.05-2g, is 8.0-9.0 with the sodium hydroxide adjust pH.
The present invention has overcome the poor problem of existing Sodium salts humic acids water treatment corrosion resisting property, and a kind of composite corrosion inhibitor is provided.This composite corrosion inhibitor nontoxic pollution-free, can with the composite use of Sodium salts humic acids water conditioner.The unique distinction of this inhibiter is, can with Sodium salts humic acids generation synergistic effect, antiscale, scale removal, sterilization algae removal and corrosion inhibition are given full play to, further improve Sodium salts humic acids water conditioner product.
Composite corrosion inhibitor is widely used, and has utilized just the synergistic effect between each component of inhibiter, can increase absorption coverage and absorption stability, changes rate of adsorption, thereby improves inhibition efficiency.There is synergy between the inhibition material owing to having utilized, reduced the consumption of inhibiter, reduced production cost, thereby promoted the fast development of inhibiter technology in modern age, enlarged the range of application of inhibiter, also solved the difficulty that single component is difficult to overcome.For example sodium oleate and hexamethylenetetramine are composite, and the lipid acid of long-chain is adsorbed on the metallic surface, form the better protecting film, hinder corrosive medium and infiltrate the metallic surface and play protective effect preferably.
Water conditioner of the present invention not only can reach the purpose of antiscale, scale removal, sterilization, but also has good corrosion mitigating effect.
