In early 2020, the novel coronavirus pneumonia epidemic broke out, and "disinfection and sterilization" became a must-have job almost every day, and disinfection and bactericide products were in short supply for a while. Disinfection and bactericide is a kind of chemical agent that can effectively control or kill bacteria, fungi, viruses, algae and other microorganisms.
In early 2020, the novel coronavirus pneumonia epidemic broke out, and "disinfection and sterilization" became a must-have job almost every day, and disinfection and bactericide products were in short supply for a while. Disinfection and bactericide is a kind of chemical agent that can effectively control or kill bacteria, fungi, viruses, algae and other microorganisms. According to its mechanism of action, it can be divided into oxidative fungicides and non-oxidative fungicides. Oxidative fungicides kill bacteria by inactivating active enzymes in bacteria or directly oxidizing them with strong oxidative properties. The main products are generally chlorine-containing and peroxide preparations, which have the advantages of strong bactericidal power, easy availability of raw materials, and simple use. However, such preparations will have a strong irritating effect on human skin, respiratory mucosa and eyes during production and use, and will produce oxidative corrosion on the surfaces of contacted objects, especially metal surfaces, and are prone to combustion and explosion during storage and transportation. Such preparations are generally used alone, and it is difficult to formulate detergents with bactericidal functions. Non-oxidative fungicides include chlorophenols, organoaldodes, quaternary ammonium salts, biguanides and other non-oxidative compounds, of which quaternary ammonium salts are an important class. Such fungicides are a class of broad-spectrum, efficient and low-toxicity fungicides, which are widely used in sterilization and disinfection in daily life and industrial fields. In the fight against the epidemic for the majority of healthcare workers and the people to provide washing, disinfection, sterilization protection of sterilization laundry detergent, sterilization hand sanitizer and other washing products, quaternary ammonium salt disinfection bactericides have played a key role.
