Nothing.
About the research of federal funding or the statement of exploitation
Inapplicable.
Background technology
At least one invention relates to for reducing bioactive composition and method in process flow such as the aqueous process stream.Biologically active in the process flow has problems because of a variety of causes, includes but not limited to hygienic issues, process equipment efficiency and product quality problem.For example, in paper technology, operation has adverse effect to the high bioactivity level to equipment.Particular type paper such as problem that thin paper/the recycled writing paper goods are relevant are more remarkable with making, this is because high fungus levels shows the dilemma, and namely providing is enough to the stable biocide agent so that it is not easy the biocide that is consumed the biocide scheme of (good continuation) and adequate level is provided to resist the contradiction between the bioactive periodicity crest (continuation of the less stabilisation of needs/reduction).And, the bleaching of regenerated fiber/processing shows other dilemmas to papermaker, this is because papermaker is wanted the adding (this can eliminate halogen such as chlorine) of the sulphite after the balance regenerated fiber is bleached/processed and the needs of the chlorine in the keeping system, more specifically, keep the constant level of chlorine in the papermaking systems and do not add contradiction between the needs of more halogen/chlorine.Therefore, require further improvement biocide-stabilizer formula and delivering method, it can mode treatment system more effective and more environmental protection, and as using chlorine/halogen still less, this also further reduces the formation of halogen accessory substance.
At least one invention relates to is stablizing effective method and composition on the oxidant biocide.Oxidant biocide such as peroxidating acid and halogen chemical such as clorox have been widely used in paper pulp and the paper industry.These oxidant biocides in time kill on a large amount of microorganisms very efficient.Unfortunately, after they were introduced in the fresh water (FW) system, oxidant biocide itself was unstable, and they are easy to Quick Oxidation and lose in time their effectiveness.In the environment that contains very high population microorganism, as in the fresh water (FW) that is rich in the organic and inorganic material that microorganism can eat, a large amount of microorganisms can survives until the oxidant biocide is lost effectiveness.Therefore, unless there are a lot of residual biocides to exist, microbial population will recover rapidly after the oxidant biocide is processed.In some cases, the bacterial strain of halogen resistant is grown because of the single-oxidizer biocide that repeats to introduce.This can cause system to be subject to the impact of bacterial growth out of control.(referring to such as textbook: Disinfection, Sterilization, and Preservation, the 5th edition, Seymour S.Block, Lippincott Williams ﹠amp; Wilkins, (2001) are at least at pp.31-57).
This problem since in many cases the repeated application of oxidant biocide be commercial infeasible fact and more complicated.Many oxidant biocides have disadvantageous side effect to other required additives of the commercial acceptable paper products of paper brightener, dyestuff and production.Repeat to add also corrodible many papermaking machines of oxidant biocide.
A kind of technology that is used for head it off is that stabilisation oxidant biocide makes it suppress the viability of microorganism in long-time section, weakens simultaneously the negative effect to gained paper and paper making equipment that the oxide biocide has.Such as United States Patent (USP) 3,328,294,3,749,672,3,170,883,5,565,109 and 7,651,622 is described, and previous trial on stabilisation oxidant biocide comprises uses sulfamic acid, salt-stabilized chlorine, monochloro amine, the halogen of DMH stabilisation, the AmBr-Cl of sulfamic acid 2Chlorine with the organic nitrogen stabilisation.Although stable a little, proved that these trials are the biocide than required more poor efficiency.The N-hydrogen source also has been used to stabilisation oxidant biocide, but they are also unsatisfactory, and this is because they are volatile and their dosage requires too strict.This stringency has hindered various flexibly molar ratios regulates, and this regulates the specific condition that often needs to adapt to its specific water system of processing.Therefore, to efficient, with other biocide compatible and on dosage and concentration variable higher stabilisation halogen biocide have and clearly need and practicality.
Another technical description of head it off is in U.S. publication application 2006/0231505A and 2003/0029812A1, and they disclose the application of biocide blend.More long-acting but the biocide of poor efficiency of the another kind that the oxidant halogen of initially killing in a large number organism is provided and provides long-acting microbial more to suppress is be provided this mixture.Unfortunately, many biocides itself are incompatible with other biocide, and use the excess investment that the multiple biocide of the various problems that have they self preparation and add need to be on complicated applications equipment.And multiple biocide dispenser is installed in along on each aspect of paper production line, has therefore greatly increased the complexity of cost and adding biocide.Therefore, need to simplify production biocide and put-on method.
Except as otherwise noted, the technology of this part description is not to admit that any patent, publication or out of Memory that this paper quotes are " prior aries " with respect to the present invention.In addition, this part should not be construed as other relevant information existence that is studied or does not have definition among the 37CFR § 1.56 (a).
