Description
Technical field
The invention belongs to chemical industry water-treatment technology field, particularly relate to one and be applied to industrial circulating water foundry loam bactericide and mud stripper.
Background technology
In industrial circulation water treatment process, it is frequently encountered corrosion and scaling, microorganism problem.Along with the raising of water technology, most corrosion and scaling problem obtains good solution, but the biological clay problem of system is still more prominent.The composition of biological clay includes the microorganism such as algae, antibacterial of all kinds of complexity, fungus and inorganic and organic impurities.These microorganisms are bonded together by the binding of epicyte, them are made to be difficult to be subject to the impact of the environmental factors (such as antibacterial, dirt dispersion agent or other Water Treatment Chemicals) beyond biological clay, so, the microorganism in foundry loam is more difficult than the microorganism of free growth mode of swimming kills.Additionally, some antibacterial is also possible to be attracted to the organic of biological clay outer layer or inorganic impurity decomposition and lost efficacy.Microorganism in biological clay not only number many thousands of up to ten thousand times than plankton, and it would furthermore be possible to cause hardware underdeposit corrosion.Therefore, the biological clay in circulation is carried out cleaning and peel off very necessary.
At present, domestic cycle cooling water system adhesive mud remover, it mostly is cationic surface active agent, mainly dodecyl dimethyl benzyl ammonium chloride (1227), myristyl benzyl dimethyl ammonium chloride (1427) etc., its peeling effect is pretty good, but in use other water treatment agents may be produced impact, simultaneously, As time goes on the progress of technology, QI-insufficiency part also displays, it is easily developed immunity to drugs by antibacterial, using dosage is big, costly, and foam is many in use, not easily it is eliminated, thus recirculating cooling water system is produced impact.Therefore development of new adhesive mud remover substitutes used adhesive mud remover product, and the safety and stability improving recirculating cooling water system operation is significant.
Summary of the invention
It is an object of the invention to: for the problem pointed out in background technology, by with double; two phenyliminos-dialkyl phenylpropyl-dodecyl dimethyl ammonium chloride for raw material, adopt by composite method, prepare the efficiently special non-oxydizing sterilization remover of circulation and solve above-mentioned technical problem.
This invention address that the technical scheme that above-mentioned technical problem adopts is as follows: one is applied to industrial circulating water foundry loam bactericide and mud stripper, this remover is made up of by ratio of weight and the number of copies following component: KF-508 bio-dispersant: 2.0-2.5 part, penetrating agent: 2.0-2.5 part, bi-quaternary ammonium salt: 15.0-16.0 part, water: 80-80.5 part.Described KF-508 bio-dispersant is: the mixture composite by dimethyl amine Medronate sodium and macromolecule organic, described penetrating agent is: dodecyl dimethyl benzyl ammonium chloride cationic surfactant, and described bi-quaternary ammonium salt is: double; two phenyliminos-dialkyl phenylpropyl-dodecyl dimethyl ammonium chloride.
The present invention, with double; two phenyliminos-dialkyl phenylpropyl-dodecyl dimethyl ammonium chloride for raw material, adopts composite method, prepares the efficient non-oxydizing sterilization remover of circulation.Containing bio-dispersant, penetrating agent and biquaternary ammonium salts bactericides in its medicament.The protective layer of sulfate reducting bacteria and nitrobacteria can be passed, it is effectively killed, be not only suitable for oil refining class circulation and be also applied for all kinds of chemical fertilizer, chemical circulation, and be environment-friendly and low-toxicity, degradable.
Beneficial effects of the present invention: the present invention is by synthesizing organic diammonium compound, this compounds adopts a connection base or claims chain bridge to be linked up by the quaternary ammonium salt molecule that two traditional, each compound molecule is made to contain two hydrophilic groups and two hydrophobic groups and the N+ ion of two positive charges.On the one hand, showing as bigger surface activity, being particularly due in molecule has two positively charged N+, is more beneficial for the biocide molecules absorption at bacterium surface, thus changing the permeability of cell wall, makes thalline break；After antibacterial is adsorbed onto phage surface, is conducive to hydrophobic group and hydrophilic group to go deep into class lipid layer and the albumin layer of somatic cells respectively, causes that enzyme loses activity.Additionally, introduce the atoms such as S, N, synergism in chain bridge, bi-quaternary ammonium salt compounds is made to have stronger sterilizing ability.The present invention not only increases remover bactericidal property, meanwhile, greatly reduces its toxicity, reduces the generation of biomolecule resistant as far as possible.Laboratory experiment and production practices have proven to the present invention and tradition mono-quaternaries Compound Phase ratio, have higher anti-microbial property and less toxicity.
