Noticeable advantage of the present invention is that sulfamic acid and nitrogen stabilizing agent are easy to combination, so that when mixing two kinds of materials, realizes high products collection efficiency and some waste is only arranged.In addition, different from the single stable agent that contains the inorganic nitrogen stabilizing agent, the mixture of sulfamic acid and nitrogen stabilizing agent works under many different ratio content.Therefore, the relative amount of sulfamic acid or nitrogen stabilizing agent can be according to the corresponding increase of its specific environment that will be used for or minimizing.For example, can disturb at the nitrogen stabilizing agent in the situation of specific Paper additive such as OBA or DYE, will increase the relative amount of sulfamic acid.On the contrary, have at sulfamic acid in the situation of consistency problem, can increase the content of nitrogen stabilizing agent.
In at least one embodiment, the content of pharmaceutical formulation is directed to biological character of invading and harassing.For example, if bacterium has just begun to permeate one or more process equipments, use contains the preparation of relative equivalent sulfamic acid and nitrogen stabilizing agent, this is because optimization is to cause low impact and the low-level corrosion on additive, this is the effect of more expecting than efficient biocide when invasion is very slight.On the contrary, when polluting very serious or long-term clustered, the effect of biocide is more important on the impact of additive or corrosion than the time, therefore uses the preparation of the more sulfamic acid of molar content that contains relative nitrogen stabilizing agent.Therefore, by using the preparation only have two kinds of variablees, can provide a large amount of condition special ratios, this needs the simple input system can be in industrial equipment dynamic response different condition in the life-span.
In at least one embodiment, with composition as the biocide in the cooling tower.
In at least one embodiment, reduce the biomembrane on surface with composition.Biomembrane is the gathering of the fixing organism on the equipment surface.Because reduced the surface of the available exposure that biocide works, usually caused particular problem so this assembles.And, usually exist biocide effect and biocide on the compromise between the biomembranous impact, yet but the present invention has avoided the illeffects of process equipment has effectively neutralized biomembrane.
In at least one embodiment, process microorganism in the film system with composition.When microorganism finds that when possessing attractability, the film system is easy to the biomembrane clustered usually for their surface (because composition, shape or the two).A little less than because also be highly brittle with respect to the process equipment film system of other form, compromise problem roughly is in film even more important.Fortunately be that said composition is effectively processed the biomembrane of film and they are not damaged.In at least one embodiment, the film system is the porous film.In at least one embodiment, film is the part of water treatment system.
In at least one embodiment, before with composition adding system, said composition has specific pH.In at least one embodiment, pH is greater than 5 and less than 12, and most preferably between 8 and 10.
In at least one embodiment, the ratio of the content of balanced combination thing is with optimization composition efficient and practicality.In the prior art, to use chloro amido sulfonate with 1: 1 ratio of chlorine.This causes stronger than the combination of desirable chlorine, and therefore this has reduced the speed that discharges sulfamate from sulphate, reduces the efficient of composition with this.In at least one embodiment, ratio is different, so composition is more effective.In at least one embodiment, the ratio of sulfamate and stabilizing agent is (less than 4) in the composition: 1 and (greater than 1): between 1.Experimental data shown in some cases the ratio of 1: 1 and 4: 1 not exclusively work or act on poor, 8: 1 to 4: 1 ratio slightly work and 3: 1 very effective as biocide.This shows that not only the beyond thought synergy based on concentration works, and this is absolute novel and beyond thought.
Embodiment
Can understand better aforementioned content by reference following examples, the purpose of following examples is explanations, and is not intended to and limits the scope of the invention.
