Due to the need for sanitation and epidemic prevention, disinfectants are needed in many places in our lives. Disinfectants are used to kill pathogenic microorganisms on the vector to make them harmless. Thereby cutting off the transmission route of infectious diseases and achieving the purpose of controlling infectious diseases.
What are the commonly used disinfectants in your life?Alcohol is often used for medical disinfection. However, not the higher the concentration of alcohol, the better the anti-virus effect. Generally 70% to 75% of alcohol is used for disinfection, and 75% of alcohol has the best disinfection effect. . Because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, and it is difficult to completely kill the bacteria; if the alcohol concentration is too low, although it can enter the bacteria, it can not coagulate the protein in the body. It is also impossible to kill the bacteria completely.
In addition, the "84 disinfectant" commonly found in life is also a kind of disinfectant, which is one of the necessary disinfection products in public places and families. 84 disinfectant is a disinfectant with sodium hypochlorite as the main active ingredient, which can kill intestinal pathogenic bacteria, pyogenic bacteria and bacterial spores. Suitable for disinfection of general object surfaces, white clothing and hospital contaminated items.
Chlorine dioxide is a new type of highly effective disinfectant with high-efficiency, broad-spectrum bactericidal action. With the improvement of living standards, people's requirements for drinking water quality are getting higher and higher. As an efficient, non-toxic and safe oxidizing disinfectant, chlorine dioxide is regarded as the first choice for tap water disinfectants.
Iodophor also has a broad-spectrum bactericidal action that kills bacterial propagules, fungi, protozoa and parts of the virus. It can be used as a disinfectant in medical treatment, it can be used for disinfection of skin and mucous membranes; it can also deal with burns, skin mold infections, etc. It can also be used for disinfection before surgery and other skins, skin disinfection at various injection sites, disinfection of instruments, etc.
Burns, frostbite, knife wounds, abrasions, contusions and other general trauma, disinfection with iodophor is also very good. Compared with alcohol, the iodophor-induced irritation is mild and easy to be accepted by patients. It is widely used and effective. Iodophor basically replaces skin and mucous membrane disinfectants such as alcohol, red mercury, iodine and purple syrup. In addition, the low concentration of iodophor is a light brown solution that does not easily contaminate clothing.
Common disinfectants are iodine, hydrogen peroxide, ethanol, potassium permanganate, and the like.
Different types of disinfectants are used differently. For example, peracetic acid and 84 disinfectant are highly irritating, preferably not sprayed in someone's room; both are corrosive and bleachable, so they are not suitable for washing clothes. At the same time, any disinfectant must be disposed of after use. If you use disinfectant when washing clothes, be sure to rinse it twice with water. Disinfecting the dish, wash it repeatedly with running water, so as not to eat the residual disinfectant ingredients into the body; Stay in the room, you should close the door for half an hour, go home and ventilate.
