Problems solved by technology

However, the slow-release disinfection products at home and abroad mainly use trichloroisocyanuric acid as the main component, or bromochlorohydantoin as the main component, plus auxiliary materials, and are solid products made by specific pressing equipment. Monitoring and measurement during use It is found that there are big problems in the slow-release and controlled-release effects of this kind of products, mainly manifested in the instability of the release curve, which is too much affected by the external environment, and the controlled release cannot be achieved, which shows that there are also problems with the stability of the preparation. Finally, in the actual use process, it is difficult to grasp the dosage and interval of drug delivery.

Abstract

The new type of slow released bromochloro disinfectant composition has dibromo Hydantoin or bromochloro Hydantoin as main component and polymer and forming agent as supplementary material and is prepared through conventional preparation process. It has the features of excellent control capacity of bactericidal factor release, long term stability, high bactericidal efficiency, broad bactericidal spectrum, high safety and environment friendship. It may be used in sterilizing and killing algae of water treating works, swimming pool, medical sewage treatment, fish pond, etc.

Description

technical field [0001] The invention relates to a novel bromine-chlorine disinfection slow-release composition and a preparation method thereof. It involves the quantitative design of chlorine bromine disinfection sustained-release formulations, and the manufacturing and processing methods of tablets, granules and other solid sustained-release products. Background technique [0002] The use of solid chloramine disinfectants has a long history. It has the characteristics of broad spectrum and high efficiency. It mainly uses chloramine compounds to react with organic decomposers, and quickly dissolves to form an efficient disinfectant aqueous solution containing hypochlorous acid. This type of product That is, the currently widely used chlorine-containing effervescent disinfectant has more applications in the medical industry, mainly used in the disinfection of surgical instruments, etc., and has a certain range of use and space, but the application cost is too high. Some pro...
