Description
Technical field
The application belongs to environmental protection reagent process field, particularly relates to a kind of nontoxic, bactericidal effect significant water treatment composite scale bactericide and preparation method thereof.
Background technology
Bactericide TH-401 is the Biocidal algae-killing agent be combined into by quaternary ammonium salt and peroxide, have efficient, wide spectrum, low toxicity, drug effect fast and the advantages such as lasting, penetration is strong, easy to use, low price, applicable temperature and pH wider range.Bactericide TH-401 is applicable to the industrial circulating cooling water systems such as power plant, chemical industry, chemical fertilizer, oil refining, metallurgy, uses as sterilization algae removal and adhesive mud remover.Adopt impact type dosing, dosage is generally 100-200mg/L, namely has thorough killing effect to Homonemeae.As suitably dosage can be strengthened for obtaining quick peeling effect when algae is more, and removing floating thing in time, when the too large impact of foam runs, can defoamer be added.
Bactericide XT-402 is the Biocidal algae-killing agent be combined into by quaternary amine and isothiazolinone, have efficient, wide spectrum, low toxicity, drug effect fast and lasting, penetration is strong, easy to use, the temperature that is suitable for and the advantage such as pH value range is wider, Long-Time Service can not make bacterium algae develop immunity to drugs.
The efficient adhesive mud remover of TH-409 has good dispersiveness and permeability, and its penetration power is strong, toxicity is low, and effect is fast, has good decomposition stripping effect to the foundry loam be made up of glutinous mud, greasy filth, bacterium algae secretion and bacterium algae etc.The efficient adhesive mud remover of TH-409, to all non-corrosiveness such as metal, rubber, plastics, soluble in waterly not to affect by the hardness of water body.Therefore be widely used in the circulation of every profession and trade and be used as sludge stripping and cleaning.The efficient adhesive mud remover of TH-409 also can make the Biocidal algae-killing agent of circulation, cleaning agent and papermaking preservative etc.
1227 is a kind of cationic surfactants, belong to non oxidizing bactericide, there is wide spectrum, efficiently sterilization algae removal ability, effectively can control bacterium algae propagation and foundry loam growth in water, and there is good sludge stripping effect and certain dispersion, osmosis, have simultaneously certain to deoil, deodorizing capability and corrosion inhibition.1227 toxicity are little, without accumulation property toxicity, and soluble in water, do not affect by the water hardness, therefore be widely used in, in the recirculating cooling water system of the industries such as oil, chemical industry, electric power, weaving, growing in order to controlled circulation cooling water system bacterium algae, having special efficacy to stabilized.1227 biocide mildewcide and softening agent, antistatic additive, emulsifier, the conditioners etc. that can be used as textile printing and dyeing industry.
The abbreviation of the English BENZOTRIAZOLE of BTA is exactly BTA.The German call of Germany's BTA just can find GERMANY YOUNGING GROUP at the English BENZOTRIAZOLE of GOOGLE English website search BTA, and being translated as Chinese is exactly German Yang Ying group.The method of translation is the trade mark result of the trade mark inquiry YOUNGING inside the China trademark net sponsored according to trademark office of State Administration for Industry and Commerce; Germany BTA content is high, and dopant species is few, and be the prerequisite that BTA can be water-soluble, content is higher, and solvability is higher, and addition is fewer.The foreign cherry BTA of Germany can use water-soluble solution, can dissolve with oil.Water is exactly the meaning of clear water, and oil, is exactly solvent, comprises ethanol, benzene, toluene, chloroform and DMF.The molten characteristic of water oil two, be doomed German foreign cherry BTA must content height impurity just to reach water less oily two molten.The foreign cherry BTA content of Germany is high, and import tariff is also high, and price is do not have advantage completely relative to domestic BTA.But for ask for something product environment-protecting asepsis, do the water treatment system of expensive goods, oil product antirust, perfect Treatment of Metal Surface, the permanent inhibition of lubricating oil, or the BTA of necessary use Water/oil dual-purpose.Germany YOUNGING ocean cherry BTA can water-soluble can oil molten, adding procedure does not need emulsifier, greatly reduces the side effect added BTA azoles and be derived.The BTA of the foreign cherry YOUGNING of Germany is applicable to domestic industrial production.
PBTCA(2-phosphate-1,2,4-butane tricarboxylate) be the phosphine carboxylic acid of new generation that last century, the eighties was invented, be a kind of low-phosphorus corrosion and scale inhibitor leading at present, be now widely used in industrial production.With dialkyl phosphites, maleic acid dialkyl in industrial production, and alkyl acrylate etc. is raw material, under strong basicity catalytic condition, through a step successive reaction synthesis.Its productive rate is 87.7%; Adopt the methods such as IR, 31P-NMR, 1H-NMR, 13C-NMR to confirm the molecular structure of synthetic product, and achieve desirable result.
One of surfactant that benzalkonium bromide is the most frequently used, there is cleaning, sterilizing and algae removal effect, being widely used in the aspects such as sterilization, sterilization, anticorrosion, emulsification, de-sludging, solubilising, is industrial circulation water treatment is conventional so far non-oxydizing sterilization algicide, one of slimes dispersant agent and cleaning agent.This product is one of the most frequently used surfactant, there is cleaning, sterilizing and algae removal effect, being widely used in the aspects such as sterilization, sterilization, anticorrosion, emulsification, de-sludging, solubilising, is industrial circulation water treatment is conventional so far non-oxydizing sterilization algicide, one of slimes dispersant agent and cleaning agent.When the control of microorganisms for circulation is with cleaning, this product and benzalkonium chloride have similar activity, but in equivalent assay situation, this product has better bactericidal activity than benzalkonium chloride.Such as under the consumption of 10mg/L working substance, this product is 98.9% to the killing rate of heterotroph, and benzalkonium chloride is 98.3% to the killing rate of heterotroph.In addition, this product has lower toxicity than benzalkonium chloride, has same application notice, and under usual service condition, its working concentration is 50 ~ 100mg/L.This product has efficiently sterilization algae removal, toxicity is little, water soluble, do not affect by the water hardness, easy to use, low cost and other advantages.And universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of corrosion mitigating effect is good, sterilizing rate is high and water treatment composite scale bactericide that scale inhibition effect is good and preparation method thereof is very important.
