What disinfectant are they spraying in china?

In 2020, the COVID-19 coronavirus has taken countless people's lives. The outbreak began in Wuhan, China, as early as January 2019. After just three months, China has basically controlled the infection and spread of the virus, and the entire social order has slowly recovered from the closure of the city and isolation to the development before the epidemic.
At present, most cities in China have resumed work, and the economy has gradually entered the formal, then, in China, what measures have the ordinary people taken to fight the virus? Below, we will explain in detail to everyone.
Since the spread of COVID-19, the protection measures of ordinary Chinese people have been mainly based on three points: wearing masks, self-isolation, and disinfection. In Chinese families, the most commonly used disinfectants are 75% alcohol disinfectant and 84 disinfectant. Not only cheap, but also convenient to buy.
There are many types of 75% alcohol series, including 75% alcohol antibacterial hand sanitizer, 75% alcohol disinfectant, etc. According to WHO, 75% concentration of alcohol has a disinfection effect of 99.99%. If the concentration is too high or too low, it cannot completely eliminate bacteria .
The 95% alcohol concentration is very high. An excessively high concentration of alcohol will form a protective film on the surface of the bacteria to prevent it from entering the bacteria and it is difficult to completely kill the bacteria. If the alcohol concentration is too low, although it can enter the bacteria, it cannot coagulate the protein in the body, nor can it completely kill the bacteria.
75% medical alcohol, because the water is mixed with alcohol, the concentration of alcohol becomes thinner. Dilute alcohol does not rush to solidify the protein on the surface of the bacteria, but penetrates into the bacteria, and then solidifies the protein in the whole bacteria. So as to achieve the purpose of sterilization. When the alcohol concentration is 75%, its sterilization ability is the strongest.
The other is 84 disinfectant, also known as 84 bleach. It is a chlorine-containing disinfectant with sodium hypochlorite as the main component. Generally, the disinfection effect of sodium hypochlorite> 5% is the most obvious. Sodium hypochlorite has strong oxidizing property and can be hydrolyzed to produce strong oxidation. Hypochlorous acid, which can oxidize reducing substances, makes the microorganisms eventually lose their function and cannot reproduce or infect. It is mainly used for disinfecting the surface and environment of objects.
84 Disinfectant has strong disinfection ability, but it must be operated according to the instructions when using it!
(1) Wear protective masks and gloves when using. 84 Disinfectant solution is corrosive and irritating to the skin and oral mucosa. If it directly contacts the original solution, it will be slightly painful.
(2) Before use, you must read the instruction manual carefully, and prepare the corresponding concentration of disinfectant according to the actual dosage. The higher the concentration of the disinfectant is, the better. The disinfectant with too high concentration can not only achieve an effective disinfection effect, but also cause environmental pollution.
(3) Sodium hypochlorite is susceptible to the influence of organic matter (such as blood, body fluids, etc.), thereby reducing the sterilization ability and affecting the disinfection effect. If there is organic matter, it needs to be cleaned before disinfection.
(4) Remember to rinse after disinfection. The residue of disinfectant will cause some harm to the human body, so after using disinfectant to disinfect tableware, tea sets, kitchen chopping boards, children's toys and other supplies, it must be washed repeatedly with clean water many times.
(5) 84 disinfectant can not be mixed with other cleaning agents such as Jielingling, it will generate chemical reaction to generate chlorine gas. Chlorine gas is a kind of gas that stimulates and damages the respiratory tract. Large amounts of inhalation of the human body can cause symptoms such as coughing, difficulty breathing, and dizziness. When the concentration of chlorine in the air reaches a certain level, it will cause chlorine poisoning, which may be life-threatening.
