DBNPA is short for 2,2-dibromo-3-Nitriloproion Amide. It is a broad-spectrum and highly effective industrial fungicide. DBNPA is mostly made use of to avoid the growth of bacteria and algae in papermaking, commercial distributing cooling water, mechanical lubricating substances, pulp, wood, paint, and plywood. This fungicide is currently the primary organic bromine fungicide.
DBNPA can rapidly permeate microbial cell membranes. Act on certain protein teams. It will certainly quit the regular redox of the cell. The branch of DBNPA can likewise precisely bromide or oxidize special enzyme metabolites of microorganisms, which eventually causes cell fatality.
DBNPA has a wide range of antiseptic residential properties. It has an excellent killing effect on microorganisms, fungis, yeast, algae, organic sludge, as well as pathogenic microorganisms.
DBNPA is defined by exceptionally rapid sanitation rate and high performance. The sanitation rate can reach greater than 99% in 5-10 mins. DBNPA was compared to the various other 3 biocides. The outcomes reveal that when the very same bactericidal impact is attained, the dose of DBNPA is just 7.5 ppm. The dose is much less than the other three fungicides.
After DBNPA is contributed to the system, its active elements can rapidly act on planktonic microbes as well as rapidly disinfect. At the exact same time, the permeability of natural bromine is better. The energetic parts in the medicament can promptly permeate the steel surface area. Act upon smaller microbial teams. Make it disaggregate swiftly. Prevents the development of biofilms.
For a system that has actually formed a biofilm, its active components do not react with the sludge layer in the biofilm. It rapidly permeated deeper into the biofilm. Microbial community acting on the border in between biofilm and also steel surface area. Breaking its viscosity, triggering the biofilm to diminish.
DBNPA can swiftly weaken right into co2, ammonia, and also bromide after the sanitation is finished. It will certainly not create the buildup of hazardous ions in the water body as well as has no influence on the setting. This makes emissions unrestricted. This is a differentiating feature of organic bromine biocides various from various other non-oxidizing biocides.
Oilfield wastewater has a high sulfate content, which is extremely helpful to the proliferation of sulfate-reducing bacteria. The expansion of sulfate-reducing microorganisms will trigger H2S web content in the water to enhance continuously. DBNPA can swiftly act on sulfate-reducing microorganisms. Before it responds with sulfate to form H2S, it can be rapidly killed.
As a non-oxidizing bactericide, DBNPA is used together with bromine-type oxidizing bactericide to boost the microbial control result of the system under regular leakage conditions.
DBNPA synergizes with bromine-based oxidizing fungicides under the severe water quality conditions of the oil refining system to much better control microbes.
DBNPA has a great peeling performance in systems where organic slime breeds severely.
After the system uses DBNPA fungicide, the air conditioning tower packaging as well as the tower wall surface are tidy, and also no sticky mud algae breeds.
DBNPA assists to preserve the recurring chlorine of brominated oxidizing fungicides.
