Anonymous users2024-01-23The main component of medical alcohol is ethanol. Medical alcohol is made by distillation of starch plants through saccharification and re-fermentation, which is equivalent to the process of making liquor, but the distillation temperature is lower than that of liquor, the number of distillations is more than that of liquor, the alcohol content is high, the output of finished products is high, and the ether and aldehyde components other than alcohol are more than wine, which cannot be drunk, but can be exposed to human medical treatment. It is a plant-based product.
UsesIn daily life, it is common for some people to use medical alcohol to scrub wounds to achieve the purpose of sterilization and disinfection. It is worth noting that the alcohol available in pharmacies has two concentrations, 75% and 95%, and the two concentrations of alcohol are not used for the same purpose.
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 (a C2H5), which can destroy the attraction between hydrophobic groups inside the protein; One end is hydrophilic (OH), but it is difficult to break the force of attraction between 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.

Anonymous users2024-01-21The main component of medical alcohol is ethanol. Medical alcohol is made of starchy plants through saccharification and then fermentation by distillation, which is quite derived from the process of making liquor, but the distillation temperature is lower than that of liquor, the number of distillations is more than that of liquor, the liquor is streamlined and coarse, the finished product is high, and the ether and aldehyde components other than alcohol are more than wine, which cannot be drunk, but can be contacted by human medical treatment. It is a plant-based product.

Furniture closely related to people's lives, if it is full of bacteria and mold erosion, people face uncomfortable feelings everywhere, which not only reduces the quality of life, but also brings terrible diseases to human beings due to the breeding of bacteria and mold, such as infectious diseases (sweat spots, athlete's foot), dermatitis in infants, bedsores in the elderly, etc. Furniture mold is mainly due to the damp environment, sofas, carpets, quilts, pillows and even plush toys may be disturbed by moisture, for fabric sofas and carpets, be sure to regularly remove dust from their surfaces, if necessary, blow gently with a hair dryer. As soon as the weather clears, it's time to put your damp furnishings in the sun.
The current national standard for formaldehyde emission of parquet is E1, that is, E1, so as long as it meets the national standard, it can be used with confidence and will not cause harm to the human body.
This depends on what the smell is, if it is a chemical substance, it is naturally not good, but some wood itself contains a strange fragrance and is beneficial.
The harm of furniture to the body lies in the content of formaldehyde, if there is not much formaldehyde, then there is no big problem, if there is more formaldehyde, it is recommended to spray more herbs. It would be better to remove formaldehyde.
