Since the mid-1970s, foreign countries have begun to develop a bromine-based bromochlorohydantoin sheet with performance and effect basically similar to that of chlorine-based disinfectant. The difference is that its corrosiveness is lower than that of chlorine-based disinfectant, but its disinfection effect is quicker Moreover, its application conditions and environmental behavior have more advantages than chlorine-based antimicrobial agents, and are called an ideal replacement for chlorine-based antimicrobial agents. At present, the market share of chlorine-based disinfectants is lower than that of bromine-based disinfectants. Bromine-based disinfectants can be described as the leading varieties in the field of disinfectants. The rate of increase is about 4%-9% per year. Its replacement products It also appeared one after another by virtue of its increasingly excellent performance.

Among the bromine-based disinfectants, the hydantoin series of bromochlorohydantoin tablets have been widely used in the disinfection treatment of biological slime treatment in paper mills, cooling water treatment, swimming pool water purification, etc., because of their many advantages. The industry values. The characteristics of this antibacterial agent are long dosage period, small dosage, wide applicable pH range and so on. It is very useful for killing microorganisms in biological slime and fungi and algae in water at a concentration of not more than 1mg/L. It is a low-damage, environmentally acceptable antimicrobial species. In view of the above characteristics, the application in Europe, America, Japan and other places has been rising steadily over the years. This kind of bromine and chlorine series sterilizing tablets are widely used in papermaking, cooling water treatment, pulp industry and swimming pool water treatment. In recent years, my country has also increased the research and development of brominated hydantoin series of sterilants, and the results are obvious, and a variety of products have been developed.

Hydantoin bromine-based antiseptics are the main products of bromochlorodimethylhydantoin, bromodimethylhydantoin, bromochloromethylethylhydantoin and bromochlorohydantoin. Bromochlorohydantoin tablets and bromodimethylhydantoin tablets are widely applicable, and their usage is larger. At present, bromo-halogenated hydantoin has the tendency to replace chlorine-based antiseptics such as chlorine chlorinated isocyanuric acid antiseptics, because of its high useful halogen content, good stability, low odor, slow release, and no damage to skin and mucous membranes. Performance characteristics, in addition, it has environmental advantages such as alkaline range operation and acceptable environmental behavior.
