The ideal chemical disinfectant should have the following conditions：

(1) The bactericidal spectrum is wide and the effect is fast.

Although researchers at home and abroad have conducted extensive screening of chemical disinfectants over the years, they have not found a disinfectant that can meet all of the above conditions. Therefore, when disinfecting, it is necessary to choose a suitable disinfectant according to the purpose of disinfection and the characteristics of the object of disinfection, that is, each disinfectant has its scope of application, and there is also a certain market space, which can obtain a better sterilization range and sterilization effectiveness through complex combinations.
