The epidemic in COVID-19 has become more serious in some places, and the epidemic has not completely ended. We must not relax our vigilance and do a good job of prevention. Alcohol disinfection is essential when you come back from home at ordinary times. There are many kinds of wine, which one is more effective for COVID-19? I brought an introduction.
What kind of alcohol can kill coronavirus? 75% alcohol can be disinfected. Alcohol does have a certain disinfection effect, but not all alcohol can inhibit and kill COVID-19. Only medical alcohol has obvious effect, and medical alcohol is a mixed solution of ethanol and water. The experiment shows that when the concentration of ethanol is 75%, its disinfection and sterilization effect is the best.

Is it better to use disinfectant alcohol at home at 75 degrees or 95 degrees?
Wipe the ultraviolet lamp with 95% alcohol. This kind of alcohol is commonly used in hospitals, but it is only used to clean camera lenses at home.
70% ~ 75% alcohol is used for disinfection. This is because excessive concentration of alcohol will form a protective film on the surface of bacteria, preventing it from entering the interior of bacteria, and it is difficult to completely kill bacteria. If the alcohol concentration is too low, it can enter bacteria, but it can't coagulate protein in the body and kill bacteria completely. Among them, 75% alcohol has the best disinfection effect.
75% alcohol is used for disinfection. When eating out, you can bring some cotton balls containing 75% alcohol. Cotton balls are soaked in alcohol, and bottles should be sealed. Before eating, wiping tableware and hands with alcohol cotton balls can prevent bacterial infection to some extent.
Alcohol is irritating to some extent, and can generally be used for local disinfection of skin, not for mucous membranes and large-area wounds. Finally, it should also be noted that after using alcohol with a concentration higher than 70%, never touch open flames to prevent burns, fires and other accidents.
What if I can't buy medical alcohol?
Here is an emergency plan: more than 75% liquor can also be used to disinfect the surface of objects, but the effect is certainly not as good as medical alcohol. This is an emergency measure and cannot be used for a long time.
Chlorine disinfectant
Note that either the name contains the word "chlorine" or a chlorine-containing disinfectant. Chlorine-containing disinfectant refers to a disinfectant that dissolves in water to produce sodium hypochlorite. And p-chloroxylenol, p-chloroxylenol, although there is chlorine in the name, actually belong to phenolic disinfectants. In daily life, 84 disinfectant, bleaching powder, chlorine-containing disinfectant powder or chlorine-containing effervescent tablets are all chlorine-containing disinfectants. After direct dilution, it can be sterilized in plastic containers. When buying, you must carefully look at the packaging and effective ingredients of the goods.
When using, be sure to avoid skin and mouth and nose. Please follow the following steps:
Wear a mask, latex gloves and waterproof apron.
At the same time, it is recommended to wear goggles to prevent the solution from splashing into the eyes and causing injury;
Bleaching solution should be prepared and used in a well-ventilated place;
Cold water should be mixed with bleach, and hot water will affect the sterilization effect;
Peroxide disinfectant
Peroxide disinfectants are widely used, among which chlorine dioxide, hydrogen peroxide and peracetic acid are representative substances. Be sure to dilute it before use.
Chlorine dioxide: suitable for disinfection of general objects and environmental surfaces, tableware, medical and epidemic prevention, etc.
Hydrogen peroxide: surface disinfection: spray, wipe or soak the surface of the object with the original solution (according to the manufacturer's instructions) for 20 minutes.
Peroxyacetic acid: generally not recommended for home use.
Peroxide disinfectant has good disinfection effect and is a safe, green and environmentally friendly disinfectant. However, most peroxide disinfectants are unstable, and long-term use will cause damage to human and animal eyes and respiratory mucosa. If it is used, it is best to choose a disinfectant prepared in the market.
