1. Application of PHMG powder in antibacterial plastic products
Bacteria, viruses and other pathogenic microorganisms are one of the main killers of human health. They can easily breed on the surface of polymer materials such as plastics and fibers, posing a great threat to the health of people who use and come into contact with these materials. Therefore, adding an antibacterial agent to the polymer material can kill or inhibit the reproduction of bacteria and viruses on the material within a certain period of time, thereby keeping the material clean and hygienic. Guanidine polymers are mainly used as antibacterial agents because they contain guanidine functional groups.
2. Application of PHMG powder in non-woven fabrics
Guanidine hydrochloride and hexamethylenediamine melt polycondensation to prepare polyhexamethyleneguanidine hydrochloride with higher molecular weight and degree of polymerization, and apply it to the antibacterial finishing of cotton knitted fabrics, so that the fabric has good antibacterial properties. It is effective and has certain durability. The synthesis, structure and molecular weight of polyhexamethyleneguanidine hydrochloride show that the prepared polyhexamethyleneguanidine hydrochloride can meet the requirements of textile antibacterial finishing; use it as textile antibacterial finishing Finishing of pure cotton knitted fabrics; Polyhexamethyleneguanidine hydrochloride has little effect on the whiteness of finished bleached fabrics and the shade of finished dyed fabrics. It has a certain resistance to washing and chlorine bleaching. It reflects the antibacterial finishing fabrics. The antibacterial activity under natural conditions, the operation is easier and faster, and the safety is higher.
