Disinfectants are often used in daily life, which can easily stimulate respiratory tract, damage intestinal flora, and affect the health of family members. Therefore, when indoor disinfection is not appropriate, it will also bring health risks to the human body.
At present, there are two types of disinfection sites on the market
Direct effect on internal genetic material nucleic acid: ultraviolet disinfection
Inactivation of proteins by acting on them: most chemical disinfectants, high temperature
The inactivation of protein mainly changes and destroys the secondary or tertiary structure by heating, dehydration, oxidation, salt formation, deamination and charge change.
Ethanol (commonly known as alcohol) can kill the virus with envelope structure, so it is effective for the new coronavirus.
Specifically, alcohol has a certain fat solubility, according to the principle of "similar solubility", it can destroy the lipid envelope composed of phospholipid bilayer; at the same time, when contacting the glycoprotein on the surface of virus envelope, it can dehydrate and denature the protein, thus inactivating the virus.
However, there are some safety risks in alcohol disinfection. For example, when using alcohol, do not close to the heat source or spray directly to the air to avoid fire; do not spray alcohol on clothes to prevent fire caused by static electricity; when disinfecting the surface of electrical appliances, remember to cut off the power supply, and all items can be reused after the alcohol volatilization.
Another well-known disinfectant is chlorine containing disinfectant. (formaldehyde removal)
All chlorine containing disinfectants have one thing in common - hypochlorite (HClO) can be produced after being dissolved in water.
Hypochlorite has small molecular weight and strong oxidation. After contacting with new coronavirus, it will oxidize the envelope protein to denature it, and damage its protein shell, so that its protein cross-linking is lost, thus further destroying the biological enzyme system and genetic genes, making it lose its activity.
Although chlorine containing disinfectants are not as easy to cause fire and damage electrical appliances as alcohol disinfectants, they also have potential safety hazards.
Chlorine containing disinfectants are generally irritant, so masks and gloves should be worn to protect them when they are configured and repackaged. Chlorine containing disinfectants are highly oxidizing and should be kept away from high temperature, fire source and children. Chlorine containing disinfectants should avoid contacting metal objects and colored clothes to avoid corrosion or fading. (formaldehyde removal)
For many enterprises and families, there are problems such as low efficiency, unsafe and unprofessional in self disinfection. Choosing a professional disinfection agency can solve these problems perfectly, which is the indoor environment quickly reaching the safety standard.
