Abstract
The invention discloses corrosion and scale inhibition biodegradable bactericide used for water treatment. The bactericide is prepared from 5-30% of hexadecyl dimethyl (2-sulphurous) ethyl ammonium, 5-20% of acrylic acid-allyloxy polyether-acrylate copolymers, 5-30% of polyquaternium, 2-25% of polyaspartic acid and 25-50% of water. The 28-day degradation rate of the bactericide reaches 90%, and the bactericide has a good bactericidal effect on microorganism soil bacteria, sulfate reducting bacteria, iron bacteria and heterotrophic bacteria, has the corrosion and scale inhibition functions, has a good dispersion effect on calcium carbonate scale and is environment-friendly bactericide used for water treatment.
Description
Technical field
The present invention relates to water conditioner technical field, especially one has the biodegradable water treatment sterilant of scale inhibitor.
Background technology
Along with the quick growth of China's economy, shortage of water resources has become one of important factor of restriction China Economic development.China's industrial water consumption accounts for 1/5th of national water consumption, but recycling rate of water used by the industries is but well below level of developed countries, wherein industrial cycle water coolant is the rich and influential family in process water, therefore the water-treated prod that development research is new and technique, improve the repeating utilization factor of industrial circulating water, the contradiction for alleviation and solution shortage of water resources and water resource waste is most important.
The market consumption of oxidative bactericide chloride in water treatment biocide is in addition very large, such as chlorine, clorox, Babysafe etc., but undeniablely all there is following shortcoming: one is dangerous large, more or less there is certain hazardness to user of service; Two is that performance can be had a greatly reduced quality in alkaline water coolant, because the hypochlorous acid playing germicidal action can form the hypochlorite of sterilization effect difference pH value more than 8.0 time.Also very large to the demand of sterilant at oil-field water process and paper industry, the conventional sterilant used as 1227, isothiazolinone effect is general, and consumption is greatly, and bacterium easily develops immunity to drugs.
Therefore, environment amenable in the urgent need to one, the water treatment biocide of excellent in sterilization effect is met the need of market.
Summary of the invention
The technical problem to be solved in the present invention is for dangerous large, consumption is large and environment is unfriendly etc. the shortcoming of current water treatment sterilant, provides one to have the biodegradable water treatment sterilant of scale inhibitor.
For solving the problems of the technologies described above, what the present invention adopted has the biodegradable water treatment sterilant of scale inhibitor, is made up of: hexadecyldimethyl benzyl ammonium (2-sulfurous acid) ethyl ammonium 5-30% following component; Vinylformic acid-allyloxy polyether-acrylic acid esters co-polymer 5-20%; Polyquaternium 5-30%; Poly aspartic acid 2-25%; Water 25-50%.
As limitation of the invention, described vinylformic acid-allyloxy polyether-acrylic acid esters co-polymer is vinylformic acid-allyloxy polyether-methyl acrylate, vinylformic acid-allyloxy polyether-ethyl propenoate or vinylformic acid-allyloxy polyether-Propylene glycol monoacrylate.
Hexadecyldimethyl benzyl ammonium (2-sulfurous acid) ethyl ammonium of employing in formula of the present invention can the serial anerobe such as stabilized (SRB), iron bacteria effectively, is a kind of non oxidizing bactericide of petrochemical industry, chemical industry, medicine, electric power, metallurgy industry circulating water treatment.This product, except having sterilization, inhibition effect, also has the ability of anti-bacteria breeding, all has special efficacy to the industrial circulating water sterilization algae removal in the chemical enterprises such as petrochemical plant, fertilizer plant, refinery, pharmaceutical factory and power station, mine.In addition, this product has excellent slimes dispersant effect, can be used for slimes dispersant and the water cooling tower purification of various refrigerating unit.
Employing doped quaternary ammonium salt series bactericidal agent mainly positively charged ion passes through the effects such as electrostatic force, hydrogen bond force and the hydrophobic binding between surfactant molecule and protein molecule, adsorb electronegative bacterial body, be gathered on cell walls, generating chamber's inhibition effect, cause bacterial growth suppressed and dead; Simultaneously its hydrophobic alkyl can also with the hydrophilic group effect of bacterium, change the permeability of film, then lysis occur, destroy cellularstructure, cause dissolving and the death of cell.This series bactericidal agent has efficiently, low toxicity, the impact not being subject to pH value change, easy to use, the feature such as have stronger stripping effect, stable chemical performance, dispersion and corrosion inhibition better to slime layer.
And the poly aspartic acid Main Function in formula is scale inhibition and/or dispersion, have corrosion inhibition concurrently.As Scale inhibitors, be particularly suitable for the formation of calcium carbonate scale, calcium sulfate scale, barium sulfate scale and the calcium phosphate scale suppressed in water coolant, feedwater and reverse-osmosis treated.Normal and vinyl polymeric dispersant (as polyacrylic acid, hydrolytic polymaleic anhydride, acrylic acid-acrylic acetoacetic ester-itaconic acid copolymer etc.), phosphine based compound corrosion inhibiting and descaling agent (as HEDP, ATMP, PBTCA etc.) etc. are re-dubbed efficient, multi-functional corrosion inhibiting and descaling agent.There is biodegradable simultaneously.
After adopting technique scheme, the product water process sterilant degradation rate of 28 days that the present invention obtains reaches 90%, has good sterilization effect to microbe soil bacterium, sulphate reducing bacteria, iron bacteria and peculiar bacterium.Having both corrosion-mitigation scale-inhibition function simultaneously, have good dispersion effect to calcium carbonate scale, is a kind of environmentally friendly water treatment sterilant.
