🎯Review 5 basic knowledge of alcohol
1. The alcohol concentration is not as high as possible
If the concentration of alcohol is too high, the effect of killing viruses and bacteria will be worse. Generally speaking, alcohol with 70~78% has the best effect.
95% alcohol: If the concentration is too high, the protein on the surface of bacteria and viruses will coagulate rapidly to form a hard film, which will cause protection, but will prevent alcohol from entering the bacteria to kill bacteria.
75% alcohol: moderate concentration, can penetrate into bacteria and viruses, completely coagulate the protein of bacteria, and have the functions of sterilization and virus removal. Alcohol with a concentration of 70-78% has a considerable effect.
2. How to buy and how much?
Because 75% alcohol is highly flammable and easy to volatilize, if it is hoarded in large quantities and not stored carefully, it is likely to cause a fire when not paying attention.
In general, the amount of storage at home should be less than 500ml, and can be divided into several small bottles; and the storage location should be far away from fire, avoid high temperature or exposure, and it is best to store in a dark place, and do not expose it to the sun.
3. How to store alcohol?
Common plastic bottle materials are very easy to be dissolved and softened by alcohol, leading to dangers of alcohol leakage. It is recommended to use the plastic bottles originally purchased for alcohol or glass bottles.
4. What can be done during disinfection?
Alcohol is recommended to be wiped and sprayed sparingly. After disinfection, open windows for ventilation to avoid fire caused by high concentrations, especially if there is high concentration of alcohol in the air, it is easy to explode due to a small fire.
It is recommended that alcohol disinfection can be used to wipe small items such as doorknobs and keys to avoid large-scale spraying, and open windows for ventilation after disinfection to reduce the concentration of alcohol in the air.
5. Where can I spray for disinfection?
Many people worry about viruses and droplets on their clothes, and they want to spray alcohol to disinfect them. But in fact, alcohol is difficult to kill the virus contained in the droplets. It is better to wash it directly; if it is a simple virus, in fact, as long as it is placed in an outdoor ventilated place for 2 hours, the virus will overflow or slowly lose its activity. It is not easy to infect people again.
Therefore, spraying alcohol on the clothes cannot achieve the effect of disinfection. On the contrary, it may cause static electricity when putting on the clothes and cause a fire due to the alcohol residue.
