3.Application scope and Usage
Environmental medical disinfection: It can be used as an external medical device and for disinfection and sterilization of skin and wounds.
Food processing industry (pipe and equipment disinfection): By using polyhexamethylene guanidine to regularly disinfect pipes, containers and factory floors, 99.9% of Escherichia coli can be killed.
Paper industry: Polyhexamethylene guanidine has good bactericidal and antibacterial properties against common microorganisms, and can also disperse and eliminate the adhesive substances produced during the deposition process.
Aquaculture industry: Highly effective in killing Vibrio parahaemolyticus, Vibrio green, Vibrio yellow, Haemophilus vibrio, Pseudomonas, and rapidly reducing the content of harmful bacteria in water bodies.
Textile industry: Wool fabrics treated with polyhexamethylene guanidine have excellent antibacterial properties and wash resistance against Staphylococcus aureus.
Agricultural fruit and vegetable disinfection: Treat seeds, bulbs or tubular seeds with polyhexamethylene guanidine. It can solve vegetable diseases; address soil problems and improve soil quality; it can also be used for the preservation and preservation of fruits and vegetables.
