Product Overview:
2.2-Dibromo-3-Nitrilopropion Amide (DBNPA) is a broad-spectrum and high-efficiency industrial fungicide.
Its used for water treatment agents, bactericidal algicide, papermaking and pharmaceutical intermediates to prevent bacteria and algae in the field of papermaking, industrial circulating cooling water, lubricants for metal processing, Wood, paint and plywood in the growth and reproduction. It also could be used as slime control agent, widely used in paper mill pulp and circulating cooling water system.
As a broad-spectrum and highly effective biocide, it can rapidly penetrate the cell membrane of microorganisms and act on certain protein groups to stop normal redox cells and cause cell death. At the same time, its branches can also selectively brominate or oxidize specific enzyme metabolites of microorganisms, eventually leading to the death of microorganisms. This product has a good peeling performance, no foam when used, liquid products and water can be any mutual miscibility, low toxicity.
Package: 25kg cardboard drum or woven bag;
Usage:
For water treatment agents, bactericidal algaecides, paper pulp, and pharmaceutical intermediates
Use range:
It is mainly used as a bactericidal algaecide to prevent bacteria and algae from growing in paper industry water, industrial cooling water, air conditioning water, metalworking lubricants, water emulsions, pulp, wood, plywood and coatings, and fibers.
Precautions:
The aqueous solution is relatively stable under acidic conditions and is easily hydrolyzed under alkaline conditions. Raising the pH, heating, and irradiating with ultraviolet or fluorescent light can greatly increase the dissolution rate. Easy to be deoxidized by reducing agents such as hydrogen sulfide to become non-toxic amines of cyanoacetic acid, greatly reducing the bactericidal rate.
