The composition for bactericidal corrosion inhibitors contains tetracycline antibiotics and a bivalent tin salt. The invention also discloses application of the composition for bactericidal corrosion inhibitors in treatment of circulating cooling water. According to the technical scheme, by applying the composition for bactericidal corrosion inhibitors to a circulating cooling water system, good bactericidal and corrosion inhibition effects can be achieved at the same time.
Description
Technical field
The present invention relates to a kind of disinfecting corrosion inhibitor composition and application thereof, particularly, relate to a kind of disinfecting corrosion inhibitor composition and the application in circulating water cooling treatment thereof.
Background technology
The running maintenance of industrial circulating cooling water system relates to the problem solving fouling, corrosion and microbiological manipulation three aspects.For solving this three problems, the cost-effective method generally adopted adds Scale inhibitors, inhibiter and sterilant.Sterilant is divided into oxidizing bactericide and non oxidizing bactericide.Conventional oxidizing bactericide has strong chlorine oil, Babysafe, organic bromine etc.; Conventional non oxidizing bactericide has quaternary ammonium salt, isothiazolinone, glutaraldehyde etc.In water treatment, the method that usual employing alternately adds oxidizing bactericide and non oxidizing bactericide carrys out the microbe population in controlled circulation water coolant.But although the chlorine series bactericidal agent instantaneous sterilization effective sterilization time length is short, and certain corrodibility is existed to carbon steel equipment.Quaternary ammonium salt easily produces resistance, and in the last few years, a lot of people was carrying out modification to quaternary ammonium salt, or searching quaternary alkylphosphonium salt replaces quaternary ammonium salt, but the lifting that sterilization effect is too large.
CN1789159A discloses a kind of disinfecting corrosion inhibitor, and this disinfecting corrosion inhibitor comprises sterilant, tensio-active agent, inhibiter, solvent and organophosphate, forms through being uniformly mixed.Described disinfecting corrosion inhibitor can play the effects such as sterilization algae removal, sludge stripping, pre-film in the recirculating cooling water system of copper material.It is narrow that this invention limits strict use range to equipment material, is mainly applicable to the recirculating cooling water system of copper material.
CN1418830A discloses a kind of both sexes disinfecting corrosion inhibitor, and this both sexes disinfecting corrosion inhibitor is made up of alkyl quaternary amine inner salt, quaternary ammonium halide, nonionogenic tenside, solvent and water.Though this disinfecting corrosion inhibitor is both sexes disinfecting corrosion inhibitor, corrosion mitigating effect is not good, and when working concentration is 40mg/L, corrosion inhibition rate only has 69%.
Microbiotic is the class secondary metabolite with antipathogen or other activity produced in life process by microorganism (comprising bacterium, fungi and actinomycetes) or high animals and plants, and other living cells can be disturbed to grow the chemical substance of function.Antibiotic antibacterial or germicidal action mechanism mainly contains 4 kinds: the synthesis of anti-bacteria cell walls, interact with cytolemma and change membrane passage, interferencing protein synthesis and suppress transcribing and copying of nucleic acid.Microbiotic is mainly for the mechanisms play effect of " bacterium has and people or other higher animal do not have ", and therefore microbiotic is multiplex with it people and animal.Also there is the agricultural antibiotic being used for farm crop at present.But do not see the report be used for by microbiotic in recirculating cooling water system.
Summary of the invention
The object of the invention is to overcome in prior art the defect being difficult to obtain sterilization and all good disinfecting corrosion inhibitor of corrosion mitigating effect, disinfecting corrosion inhibitor composition and the application thereof all preferably of a kind of sterilization and corrosion mitigating effect is provided.
To achieve these goals, the present inventor has carried out a large amount of experiments, found that, tetracycline antibiotics and stannous salt is coordinated and not only has preferably sterilization effect as disinfecting corrosion inhibitor, also have good corrosion inhibition.Therefore, the invention provides a kind of disinfecting corrosion inhibitor composition, wherein, this disinfecting corrosion inhibitor composition contains tetracycline antibiotics and stannous salt.
