Anonymous users2024-02-11It cannot be used for disinfection. Industrial alcohol is used for disinfection, and the concentration of ethanol in industrial alcohol cannot reach the concentration of 75% of the applied alcohol, and it cannot effectively kill bacteria, viruses and other pathogenic microorganisms. Industrial alcohol usually contains a lot of impurities, such as formaldehyde, acetaldehyde, etc., which not only do not have any disinfection effect, but will cause great harm to the human body.
Therefore, 75% alcohol should be used for disinfection or sterilization, rather than industrial alcohol for disinfection. Industrial alcohol disinfection will not play a role in disinfection, but will cause great harm to the human body, and its gains will outweigh the losses.

Anonymous users2024-02-10It is very clear to you that this situation is very dangerous, because the alcohol should be relatively said that the current disinfectant alcohol is 75%, and only the special one is 49%, so at this time, the alcohol used in the case of Chi Pei in the cavity of the field is not very circulating, Wu Dan ridge is easy to be flammable and explosive, so you must pay attention to it at this time. There is also a lot of ultraviolet radiation, that is to say, it can kill bacteria in the air, about 10 minutes, its effect can be revealed, so it is not recommended to use a closed space at this time, because its heat and penetration are very strong, easy to cause hidden dangers and fires.

Anonymous users2024-02-09Long-term disinfection with 75% alcohol may cause the resistance of the bacteria to it, thus reducing or even losing the sterilization effect and leading to unnecessary errors, the disinfection of the instrument can be used alternately with benzalkonium bromide, and the direct use of the human body can be used alternately with iodine wine.
Industrial alcohol cannot be used for the disinfection of the human body, because methanol will cause poisoning, and some of it will be absorbed for disinfection, and it can lead to blindness and even death after poisoning.
Disinfection mechanism. To denature proteins, it is necessary to stretch and relax the long chains of protein molecules that are curled and helixed, and the key is to destroy the various forces that form curls and helixes.
The alcohol molecule has two ends, one end is hydrophobic (-ch), which can destroy the force of attraction between hydrophobic groups inside the protein; One end is hydrophilic (-OH), but it struggles to break the force of attraction between the hydrophilic groups on the outside of the protein.
On the other hand, although the water molecule can relax the attraction between the hydrophilic groups of the protein, it cannot destroy the attraction between the hydrophilic groups in its protein even if it burrows inside the bacteria.
Therefore, neither pure alcohol nor water is sufficient to denature the protein within the bacteria, and the protein will lose its physiological activity only if alcohol and water coexist while relaxing the various attractions that maintain the geometry of the protein. Therefore, only a certain concentration of alcohol solution can achieve a good disinfection and sterilization purpose.

84 is calcium hypochlorite, that is, a low-concentration bleach aqueous solution, do not disinfect clothes, otherwise... It is not good to use the same disinfectant for a long time, because it is impossible for general disinfectants to kill all bacteria, which may cause an imbalance in the bacterial population and form double pollution. You can add me for a detailed explanation. >>>More

Argon itself is not toxic, but it has a suffocating effect at high concentrations. There is a risk of suffocation when the concentration of argon in the air is higher than 33%. When the concentration of argon exceeds 50%, severe symptoms appear, and when the concentration reaches more than 75%, death can occur within minutes. >>>More
