Abstract

The invention relates to a solid-liquid combined peracetic acid disinfectant and a preparation method thereof, relates to the technical field of disinfectant and venom, and is mainly used for disinfection and sterilization of soft endoscopes. After A and B are mixed, dissolved and diluted, sterilization can be achieved within 10 min, and disinfection can be achieved within 5 min. Enteropathogenic bacteria, pyogenic cocci, pathogenic saccharomycetes, bacterial spores, aspergillus niger and tortoise mycobacteria can be killed, and viruses can be inactivated. The pesticide has the advantages of high efficiency, broad spectrum, quick effect, good safety, simple and fast use, and no corrosion. Particularly, the agent B in the composition is solid powder, and the agent A and the agent B are mixed and dissolved to form a concentrated solution which can be diluted by 6 times for use, so that the logistics cost is saved. The device is suitable for high-level disinfection and sterilization of various medical instruments, endoscopes and the like in medical and public institutions.

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a solid-liquid combined peracetic acid disinfectant and a preparation method thereof. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] Peracetic acid is a kind of disinfection (sterilization) agent belonging to peroxides. It is an internationally recognized high-level disinfection and sterilization agent. It has the advantages of guaranteed bactericidal effect, high efficiency, no residue, and green environmental protection. Proteins in bacteria are oxidized, thereby killing microorganisms. At present, the commonly used peracetic acid on the market includes unit peraceti...
