Abstract
The invention relates to a germicide used in an industrial circulation cooling water system and is characterized in that the germicide contains the following components: 1-3% of mixture of 5-chlor-2-isobutyl-4-isothiazole-3-one and 2-isobutyl-4-isothiazole-3-one or mixture of 5-chlor-2-butyl-4-isothiazole-3-one and 2-butyl-4-isothiazole-3-one, 3-10% of solution adjuvant, 0.1-1% of stabilizer and water in balance. The germicide, in common concentration, is compatible with chlorine, corrosion inhibitor and scale inhibitor in water. When used in the closed circulation cooling water system, the use amount of the germicide is low, thereby preventing drug resistance of bacteria. Additionally, the germicide doesn't produce foams and is not antagonistic to water stabilizer in the circulation cooling water system of blast furnace.
Description
Technical field:
The present invention is specifically related to a kind of bactericide that is used for industrial circulating cooling water system.
Background technology:
In industrial circulating cooling water system, along with the cooling water system increase of running time, the breeding of various bacteriums and algae will aggravate, the pipeline or the reduction heat exchange efficiency of the biological clay meeting occluding device that bacterium and algae reproduction produce, also can produce underdeposit corrosion simultaneously, make water quality deterioration, thereby influence industrial production.For suppress, killing microorganisms and algae, adopt the method that adds Biocidal algae-killing agent usually.
Biocidal algae-killing agent commonly used at present has chlorine, chlorine dioxide, clorox, chlorinated isocyanurates, quaternary ammonium salt, glutaraldehyde, isothiazolinone etc.The present Biocidal algae-killing agent that the uses method that adopts two kinds of medicaments alternately to add mostly in use, dosage more (generally more than 80mg/L), and microorganism is easy to generate drug resistance, and use cost is higher, and the foam that produces in the use is more.
Summary of the invention:
It is less to the purpose of this invention is to provide in the inclosed recirculated cooling water system when using dosage, bacterium is difficult for producing drug resistance, and medicament does not produce foam, and medicament itself and blast furnace closed system water quality stabilizer can not produce a kind of bactericide that is used for industrial circulating cooling water system of antagonism.
The present invention is made up of following material: be the mixture 1%～3% of 5-chloro-2-isobutyl group-4-isothiazoline-3-ketone and 2-isobutyl group-4-isothiazoline-3-ketone by weight percentage; Cosolvent 3%～10%; Stabilizing agent 0.1%～0.3%; All the other are water.
5-chloro-2-isobutyl group-4-isothiazoline-3-ketone, 2-isobutyl group-4-isothiazoline-3-ketone are organic sulfur compound biocides efficiently, when it with can promptly suppress microbial growth after microorganism contacts, and this effect is irreversible, finally cause the death of biological cell, before cell death, synzyme and secretion have adhering material and biomembrane material again through the microorganism of treated with same.Simultaneously can also pass the foundry loam top layer at an easy rate, thereby kill the microorganism in the foundry loam, 5-chloro-2-isobutyl group-4-isothiazoline-3-ketone, the 2-isobutyl group-existing bactericidal property rapidly of 4-isothiazoline-3-ketone can also stop the formation of foundry loam effectively.5-chloro-2-isobutyl group-4-isothiazoline-3-ketone, 2-isobutyl group-4-isothiazoline-3-ketone can be controlled miscellaneous algae, fungi and bacterium in the cooling water, and in the pH value scope of broad the good performance of killing livestock be arranged all.
Under common working concentration (concentration of sterilant is 80-100mg/L), can be compatible with each other in water with chlorine, corrosion inhibiter and antisludging agent, under the working concentration of recommending (concentration of sterilant is 80-100mg/L), be a kind of biocide of low toxicity, and lasting medicine, bacterium are difficult for producing drug resistance.The foam that do not produce soluble in water.
