The invention discloses high-efficiency scale inhibition and dispersion bactericide and a preparation method thereof. The high-efficiency scale inhibition and dispersion bactericide comprises, by weight, from 15 to 40 parts of amino sulfonic acid, from 20 to 30 parts of polymaleic anhydride, from 10 to 15 parts of sodium molybdate, from 10 to 15 parts of phosphonic hydroxy acid-PBTCA (phosphonobutane-1, 2, 4-tricarboxylic acid), from 30 to 50 parts of benzyl ethoxyl imidazoline quaternary ammonium salt, from 5 to 18 parts of imidazoline derivatives, from 1 to 5 parts of dimethylformamide and from 30 to 50 parts of distilled water. The high-efficiency scale inhibition and dispersion bactericide is applicable to circulating water with high hardness (ranging from 10mmol/L to 12mmol/L), high alkalinity (ranging from 10mmol/L to 12mmol/L) and high temperature (ranging from 60 DEG C to 85 DEG C), and has good scale inhibition, corrosion inhibition and sterilization effects.
Description
Technical field
The present invention relates to the technical field that water treatment agent is produced, particularly a kind of efficient scale disperses sterilant and method of manufacture thereof.
Background technology
The water resources poorness is a great problem of China facing always, and along with the developing rapidly of domestic economy, water consumption sharply rises especially in recent years, and the pollution of water resources also is on the rise.The Treatment of Industrial Water technology is polluted, prolonged service life of equipment etc. for conserve water resource, minimizing water, and is significant.Therefore, along with improving constantly of Treatment of Industrial Water and environmental protection requirement, domestic water conditioner kind is enriched constantly, and performance improves constantly.According to the requirement of Sustainable development, the greenization process of water technology will be accelerated, and develops the green water treatment agent agent (being commonly called as water quality stabilizer) that is fit to the environment protection demand; It is the one big type of fine chemical product that is used for industrial circulating cooling water system; Comprise Scale inhibitors, dispersion agent, inhibiter, coagulating agent, help chaste tree, biocide, clean-out system and skimmer etc. with fixed attention, be widely used in chemical industry, metallurgy, chemical fibre, pharmacy, generating, oil production and other any industrial sector that needs the application cycle water coolant, the research and development of Chinese water conditioner have obtained certain achievement; Especially in recent years; The novel water conditioner of developing successively, green water conditioner and clean production, but because the industrial development history of domestic water treatment agent is shorter; A little less than the relative thin of basis; With abroad compare, backward in technique, integral level is not high.Therefore, along with the raising of global environmental consciousness, the efficient compound scale inhibition disperses the research of sterilant to become the research direction of water quality stabilizer.
Summary of the invention
The object of the present invention is to provide a kind of efficient scale to disperse sterilant and method of manufacture thereof; Mainly solve above-mentioned existing in prior technology problem; It is applicable to high firmness (10~12mmol/L), high basicity (10~12mmol/L), high-temperature water quality (60~85 ℃), have preferably scale inhibition and disperse sterilization effect.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of efficient scale disperses sterilant; It is characterized in that: it according to the composition of parts by weight is 15~40 parts of amidosulfonic acids, 20~30 parts of HPMAs, 10~15 parts of Sodium orthomolybdates, 10~15 parts of phosphine hydroxy acid-PBTCA, 30~50 parts of benzyl oxyethyl group imidazoline quaternary ammonium salts, 5~18 parts of imidazolidine derivatives, 1~5 part of N, 30~50 parts of zero(ppm) water.
A kind of efficient scale disperses the method for manufacture of sterilant, it is characterized in that: its process step is, A, zero(ppm) water joined in the reaction vessel and stirs; B, in container, add amidosulfonic acid and stir; C, in container, add HPMA, fully stir it is mixed; D, in container, add Sodium orthomolybdate and phosphine hydroxy acid-PBTCA, fully stir, mix; E, to container the order add benzyl oxyethyl group imidazoline quaternary ammonium salt, imidazolidine derivatives, N, stirred 3 hours, stir, get product.
The advantage that prescription of the present invention and method can embody is.
1, sodium acetate base oxethyl imidazoline quaternary ammonium salt, benzyl oxyethyl group imidazoline quaternary ammonium salt can with the one or more metal ion-chelants in iron, copper, zinc, aluminium, calcium, the magnesium plasma; Forming the dicyclo of three-dimensional arrangement or encircling inner complex more to be scattered in the water; The normal crystallization of incrustation scale is destroyed, suppress the generation of various salt crust effectively, its chemicalstability is good; Simultaneously mikrobes such as sulfatereducting bacteria common in the system are had significantly and kill, suppress effect, have inhibition, bactericidal property concurrently.
2, HPMA, phosphine hydroxy acid-PBTCA, Sodium orthomolybdate are under the effect of terepthaloyl moietie, through one type of water-soluble high-molecular compound of homopolymerization formation.The deposition that can stop lime carbonate or calcium phosphate scale; Corrosion inhibition rate is high, and the carboxyl functional group article on plasma in its compound has stronger sequestering power simultaneously, and dispersion, cohesion are not only arranged; Can also in the inorganic scale crystallisation process, disturb the normal alignment of lattice, thereby play scale effect.
3, the thionamic acid in the mixture can be removed the incrustation scale and the corrosion product of the equipment surface of made such as iron, steel, copper, stainless steel.
4, safety and environmental protection, free from environmental pollution.
