According to the novel coronavirus novel coronavirus infection diagnosis and treatment plan, 75% of alcohol has a good killing effect on the new coronavirus. Therefore, the majority of people are using alcohol 75% for anti-virus in the near future, but the editor reminds us to use the right methods, understand the precautions in the use process, and prevent fire and personal accidents.
Alcohol 75% is used for disinfection. This is because the excessive concentration of alcohol will form a protective film on the surface of the bacteria to prevent it from entering the body of the bacteria, so it is difficult to kill the bacteria completely. If the alcohol concentration is too low, although it can enter the bacteria, it can not coagulate the protein in the body, nor can it kill the bacteria completely.
The difference between industrial alcohol and medical alcohol 1. purity Medical alcohol refers to the alcohol used in medicine. There are many kinds of purity of medical alcohol, the common ones are 95% and 75%. 75% alcohol is suitable for disinfecting intact skin without wound. For skin with wound, do not disinfect with 75% alcohol, which will cause strong tingling and affect wound healing. Industrial alcohol refers to the alcohol used in industry. The purity of industrial alcohol is generally 95% and 99%.
2. Toxicity Because of its low concentration, medical alcohol can be used for disinfection of human body. Industrial alcohol can not be used for disinfection of human body, because methanol will lead to poisoning, and some of it will be absorbed by the skin when it is used for disinfection of skin. After poisoning, it can lead to blindness or even death.
3. usage Medical alcohol is mainly used for disinfection and sterilization. Industrial alcohol can be used in printing, electronics, hardware, perfume, chemical synthesis, pharmaceutical synthesis, etc. It can be used as cleaning agent and solvent.
When using alcohol to disinfect indoors, good ventilation shall be ensured. Used towels shall be cleaned with clear water and then placed in the ventilation place to dry. Before using alcohol, the inflammables around the place of use shall be removed. When using, it shall not be close to the heat source and avoid the open fire. Before using alcohol to disinfect the surface of electrical appliances, the power supply shall be turned off first and the electrical appliances shall be cooled down.
When alcohol 75%, 84 disinfectant, sodium hypochlorite and other disinfectants are used for disinfection, self-protection must be done well. The disinfectant contains irritancy, and long-term contact will cause certain damage to the human body. Therefore, masks and gloves must be worn during disinfection to prevent splashing on the human skin.
