Anonymous users2024-02-10Alcohol is volatile, can take away part of the surface bacteria, and 70%-75% of the alcohol is used for sterilization and disinfection, and the anti-virus effect is very good, but alcohol can only destroy part of the bacteria, high temperature disinfection is generally the use of high temperature to inactivate some bacteria, so as to achieve disinfection, but there is no real sense of 100% or complete disinfection.

Anonymous users2024-02-09Alcohol is volatile, in addition to taking away part of the surface bacteria, it can also denature bacterial proteins, the effect of using 70%-75% alcohol is better than 95%, because 95% alcohol volatilizes faster. However, alcohol can only destroy some bacteria, and high-temperature disinfection is the use of high temperature and high pressure to inactivate bacteria, so as to achieve the purpose of disinfection.

Anonymous users2024-02-08Because alcohol and high temperature can change the structure of protein molecules, so the structure of the virus changes.

Anonymous users2024-02-07The sterilization principle of alcohol and high temperature is to penetrate bacteria and coagulate and denature them by destroying the proteins they reproduce.

Anonymous users2024-02-06High temperature changes the denaturation of protein molecules, and the same is true for alcohol.

Anonymous users2024-02-04We don't know why high-concentration alcohol can have so many disinfecting effects, and for high-concentration alcohol, it can also help us to be in a certain safe state in our lives. Then we usually see some people, after they fall and are injured, or their own ** has some extra wounds, they will use high concentration of alcohol to disinfect, this water is a certain help for themselves. Then the high concentration of alcohol can make the coagulation of some proteins stronger and stronger, and for such high concentration of alcohol, when in contact with bacteria, the surface of such bacteria can be quickly coagulated.
Because it can stop the invasion of bacteria.
It will allow some of these bacteria to form a protective film, and prevent the alcohol from continuing to penetrate into the bacteria. At this time, some cells inside the bacteria can be completely killed, so at the right time, some cells in the envelope can break through the envelope and resurrect. And we can also see that if there are some alcohol concentrations that are very good, we can feel that some of the proteins that make up the bacteria have coagulated.
If we experiment, we will also feel that it can help us to reach a certain state. <>
Prevent us from being harmed.
And the common name of alcohol is such a kind of ethanol, which is actually a commonly used disinfectant. We will feel that we are usually very effective when we wipe some of our own wounds, and we are able to block our own contact with germs sufficiently, thus reducing our own damage. Usually after we have a traumatic injury on our own body, we will disinfect it with alcohol, and such a disinfection method has also been recognized by everyone.
Because after all, everyone thinks that after alcohol is disinfected, let our own ** be in a protected state. At this time, it will also allow our own muscle tissue to regenerate, and it will not leave scars due to the influence of such bacteria.

Anonymous users2024-02-03Because most bacteria will die under high concentrations of alcohol, they can also kill all these bacteria in this case, which is one of the most important reasons why high concentrations of alcohol can be disinfected.

Anonymous users2024-02-02Because alcohol can absorb bacteria, the moisture of the egg white can dehydrate and denature and solidify, so it can achieve the purpose of killing bacteria at this time, so it can be disinfected.

Anonymous users2024-02-01It is because alcohol has a very strong ability to penetrate and can penetrate the inside of bacteria, so alcohol can have a disinfectant effect.

Anonymous users2024-01-31Hello! I'm happy to answer your questions, and here's what I've got for you:
75% alcohol wipes can be used to disinfect. The main ingredient of 75% alcohol wipes is alcohol, and the alcohol concentration of this kind of wipes can reach 75%, so it has a disinfection effect.
75% alcohol wipes need to be careful when using, do not use them in places with relatively high temperatures, because the ignition point of this kind of thing is relatively low, and if it is used in places with relatively high temperatures, it is easy to burn.
75% alcohol wipes are not recommended to wipe clothes in a large area, clothes are very easy to generate static electricity, if static electricity occurs during use, the consequences are unimaginable.
75% alcohol wipes should be properly stored in a cool place, avoid balconies, places with fires, and out of the reach of children.
Do not put 75% alcohol wipes in the car, the temperature in the car will be very high in summer, and it is very dangerous to put 75% alcohol wipes in the car at this time.
75% alcohol wipes are suitable for use in well-ventilated places, and alcohol wipes should be kept away from some flammable and explosive materials when using them. Before discharging the surface of the appliance and the state surface, the power should be turned off, and then gently wiped with alcohol after cooling, which is safer.

Anonymous users2024-01-28Hospitals often use alcohol to disinfect patients' wounds, and alcohol has a good disinfection effect, so many hospitals have a strong smell of home alcohol, so why can alcohol be disinfected? What is the reason for alcohol disinfection? Let's find out with me.
Alcohol disinfection works by coagulating proteins in the bacteria's body, thereby killing the bacteria. However, 95% alcohol can quickly coagulate the proteins on the surface of the bacteria and form a protective film to prevent the alcohol from entering the bacteria, so it cannot completely kill the bacteria.
If the alcohol concentration is less than 70%, it can enter the bacteria, but it cannot coagulate the proteins in the body, and it cannot completely kill the bacteria. Only 70%-75% alcohol can enter the bacteria smoothly, and can effectively coagulate the proteins in the bacteria, so it can completely kill the bacteria.

Anonymous users2024-01-27The molecule of alcohol (ethanol) has a great ability to penetrate, it can penetrate the membrane on the surface of bacteria, penetrate into the interior of bacteria, change the molecular structure of proteins that make up the basis of bacterial life, cause protein denaturation (protein coagulation), and thus play a bactericidal role. In addition to this, alcohol can also change the molecular structure of amylase (a protein), making it inactive and catalytic.
When the concentration of alcohol is too high, a large number of denatured proteins form a hard membrane on the surface of the bacteria that prevents alcohol molecules from penetrating further into the bacteria, and this membrane plays a role in protecting the bacteria.
Alcohol at a concentration of 75 has the strongest bactericidal power. (i.e. medical alcohol).
It is not a very wise choice to use a nose sticker, there will be fewer blackheads after use, but the pores on the nose will also open and become larger, and the nose is not as elastic as other parts, if there are a lot of blackheads on the nose, the best advice is to go to a beauty salon, where there are professional solutions. You can also buy that kind of special blackhead export liquid, dip some export liquid on the nose with a cotton pad for a few minutes, and then take off the cotton pad There will be a lot of blackheads, blackheads are sucked up, of course, the pores have become a lot bigger, at this time, you need to apply a tightening pore**, there are single buys and there are also export liquid with **, not expensive, dozens of yuan is good. Some people will use acne injections at home to squeeze out blackheads, which is also feasible, but it is important to remember that you must not forget to shrink your pores, and these actions are best done at night, because there will be a night of repair time at night, and you will not come into contact with dust and dirt from the outside world.
