Description
Technical field
The invention belongs to water treatment agent technical field, be specifically related to a kind of Treatment of Industrial Water bactericide.
Background technology
The poor a great problem being China always and facing of water resource, developing rapidly especially in recent years along with domestic economy, water consumption sharply rises, and the pollution of water resource is also on the rise.Treatment of Industrial Water technology for saving water resource, to reduce water pollutions, extension device service life etc. significant.And the pollution of industrial circulating water system mainly primarily of microorganism the organic attachment growing formation caused by.In cycle water, microorganism generally refers to bacterium and algae.Along with the increase of industrial circulating water cycle-index, due to the enrichment method of nutrient, the rising of water temperature and illumination create condition to the rapid breeding of bacterium in industrial circulating water and algae.On the one hand, microorganism causes the direct pollution of water body; On the other hand, the microorganism in industrial circulating water brings great harm to equipment, a large amount of glutinous mud that it produces, in cycle water, cause corrosion, and glutinous mud is attached to metal surface generation fouling and hinders its heat transfer, significantly reduces circulating cooling effect.Therefore controlling the microorganism in industrial circulating water and process to control degenerating of water quality, and can reduce the service life of energy consumption, prolongation instrument and equipment, is the key of circulating water cooling treatment.
The bactericide that current industrial circulating water uses, aerobic type bactericide and non-oxygen type bactericide can be divided into by its sterilization mechanism, conventional aerobic type bactericide adds liquid chlorine, clorox, chloramines, chlorine dioxide etc., and non-oxygen type bactericide is as cationic surfactant 1227.But the problems such as toxicity is large, difficult degradation that this series bactericidal agent exists, cause the residual quantity of bactericide in water too high, particularly aerobic type bactericide, chlorine and the organic matter in water react, the organochlorine compound of generation carcinogenicity; These bactericide also can have strong reactivity to the material of equipment and pipeline, easily cause corrosion or corrode, will certainly reduce the germicidal efficiency of these bactericide and bring extra equipment damage.Simultaneously, the vitality of the bacterium in water is extremely strong, can develop immunity to drugs to the bactericide of one or more Long-Time Service, must cause the problems such as the germicidal efficiency of bactericide declines, dose increase, therefore, need constantly to research and develop new industrial water conditioning agent and substitute the bactericide generally used at present.
Summary of the invention
The object of this invention is to provide a kind of Treatment of Industrial Water bactericide, meet the requirement of industry water microbial diversity sterilization processing, also there is the advantage of low, the easy degraded of toxicity simultaneously.
For achieving the above object, the present invention is by the following technical solutions:
A kind of Treatment of Industrial Water bactericide, it is made up of the raw material of following portions by weight:
Glycosyl gemini quaternary ammonium salt 18 ~ 25 parts
Alkyl glycoside 2 ~ 5 parts
Isothiazolinone 4 ~ 10 parts
Sodium dichloro cyanurate 5 ~ 10 parts.
Described glycosyl gemini quaternary ammonium salt is carbon chain lengths is C
8~ C
14glycosyl gemini quaternary ammonium salt in one or both combination, the structure of glycosyl gemini quaternary ammonium salt is as follows:
Wherein R=C
nh
2n+1, n=8 ~ 14.
Described alkyl glycoside is as bleeding agent, and employing carbon chain lengths is C
8~ C
14alkyl glycoside.
A kind of preparation method's step of Treatment of Industrial Water bactericide is as follows: glycosyl gemini quaternary ammonium salt, alkyl glycoside, isothiazolinone and sodium dichloro cyanurate are weighed by formula, add successively in stirred tank, namely mechanical mixture evenly obtains Treatment of Industrial Water bactericide.
Beneficial effect of the present invention:
(1) mechanism of action of quaternary ammonium salt bactericide is: cation is by effects such as electrostatic force, hydrogen bond force and the hydrophobic bindings between surfactant molecule and protein molecule, adsorb electronegative bacterial body, be gathered on cell wall, 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 cell structure, cause dissolving and the death of cell.This quaternary ammonium salt is the double-type cationic surfactant containing glycosyl, and double-type cationic surfactant is larger than the positive charge density of common cation surfactant, has less critical micelle concentration and stronger sterilizing ability.The density of positive charge is larger, is more conducive to penetrating bacterium surface cell wall, makes antibacterial agent have better bactericidal effect.Two alkane chains of Gemini surface active agent simultaneously with cellular lipids layer generation hydrophobic binding, stronger than the hydrophobic effect of single alkane chain, also enhance bactericidal effect.Introduce glycosyl in traditional cation surfactant molecule after, the biological degradability of this cationic surfactant is improved, is conducive to environmental protection.This series bactericidal agent has efficiently, low toxicity, be not subject to pH value change impact, easy to use, have stronger stripping effect, stable chemical performance, dispersion and corrosion inhibition better to slime layer.
(2) alkyl glycoside is carbon chain lengths is C
8~ C
14alkyl glycoside.It is fast that this Novel alkyl glucosides bleeding agent has seepage velocity, do not affect by other ionic species and concentration in water, is conducive to promoting that sterilization component enters bacterial cell, and Synergistic improves bactericidal effect, also has the stripping effect to bacterium algae mud.
(3) isothiazolinone is key by disconnecting bacterium and algae protein matter and plays to kill livestock and act on.After isothiazolinone contacts with microorganism, can promptly irreversibly suppress it to grow, thus cause the death of microbial cell, therefore to common bacteria, fungi, algae etc., there is very strong suppression and killing action.Efficiency of killing livestock is high, and degradability is good, has and does not produce the features such as residual, handling safety, compatibility are good, stability is strong, use cost is low.Can with chlorine and most of anions and canons and non-ionic surface active agent miscible.During high dose, isothiazolinone is peeled off biological sludge in industrial remarkable result.
(4) sodium dichloro cyanurate is sterilization one of wide spectrum, efficient, safe disinfectant the most in oxidizing bactericide, is also the leading products in chlorated fulminuric acid class.Can kill fast and the powerful algae such as blue-green alge, red algae, marine alga suppressing the systems such as cycle water, cooling tower, pond.Killing action is thoroughly had to the sulfatereducting bacteria, iron bacteria, fungi etc. of circulation.Thoroughly kill the bacterium algae propagation in the equipment such as system pipeline, heat exchanger, cooling tower, solve bacterium algae and form the problems such as the blocking of glutinous mud, corrosion pipeline
(5) the composite Treatment of Industrial Water bactericide of Four composition provided by the invention, is played the potentiality of each component to greatest extent, meets the requirement of industry water microbial diversity sterilization processing by Synergistic.Bactericide provided by the invention also has the advantage of low, the easy degraded of toxicity.
