After the outbreak of COVID-19 epidemic, the demand for 84 disinfectant increased quickly, which was hard to buy. Previously, this low-cost, easy-to-use, and reliable disinfectant has played a huge role in defeating hepatitis A and SARS epidemics, and can be called an "artifact" for epidemic prevention.
Why is it called "84 disinfectant"? Some people say that "84" is a homophony of "Pasteurization", and that "pasteurization" is currently a universal disinfection method in the world. In fact, this statement is incorrect! "84 disinfectant" is called "84" only because it was invented in 1984. In 1984, the Beijing No.1 Hospital for Infectious Diseases developed a disinfectant that can quickly kill all types of hepatitis viruses. At first, its name was "84 Hepatitis Decontamination Liquid", and later it was changed to "84 Disinfectant".
The main disinfectant component of 84 disinfectant is sodium hypochlorite (NaClO), with an effective chlorine content of 5.5% to 6.5%. It is a colorless or yellow liquid with a pungent odor. The carbon dioxide (CO2) in the air dissolves in 84 disinfectant and reacts with sodium hypochlorite to generate bleaching hypochlorous acid, thereby exerting a disinfection effect.
Please pay attention to the following points when using:
Wear protective masks and gloves;
Three elements of effective disinfection: disinfection method, disinfectant concentration, and working time, all of which are indispensable;
When disinfecting the indoor environment, please pay attention to ventilation;
Place the 84 disinfectant away from children.
In addition, although 84 disinfectant is powerful, it cannot be used at will! Remember not to mix with the following match!
The mixture of 84 disinfectant and medical alcohol may produce chlorine, which is a highly toxic gas. Once inhaled, it can easily infect the respiratory tract and lungs, causing bronchitis and pulmonary edema. Excessive inhalation can cause cardiac arrest.
Be careful if you have "Toilet Cleaner" at home, it is the enemy of "84 disinfectant"! The main component of 84 disinfectant is sodium hypochlorite, and the main component of Toilet Cleaner is hydrochloric acid. And the mixture of the two will produce a chemical reaction to generate chlorine, which is no longer "disinfection", but "toxin production"!
After the laundry detergent and 84 disinfectant are mixed, a neutralization reaction will occur, which not only destroys the disinfection effect of 84 disinfectant, but also reduces the effective ingredients in the laundry detergent. In addition, some of the ingredients in the laundry detergent react with 84 disinfectant to produce toxic substances.
