New coronaviruses are on the rise, it is important to prevent new coronaviruses, and do a good job of disinfection. Protecting yourself and your family with scientific means is also a contribution to fighting the virus together.

 Q1, first of all, which disinfectants are viruses sensitive to?

The new coronavirus is sensitive to almost all disinfectants. The virus is sensitive to ultraviolet light and heat. 56 ℃ 30min, 75% ethanol, benzalkonium bromide, chlorine disinfectant, peracetic acid, hydrogen peroxide, etc. can effectively inactivate the virus.

Q2. How to disinfect indoor air and articles?

(1) Alcohol: Alcohol can denature and solidify the protein of bacteria. 75% medical alcohol can be used to disinfect the skin.

(2) Steamer: disinfection can be achieved within 20 minutes from boiling. Suitable for sterilizing tableware, clothing and gauze for wound dressing.

(3) Boiling: the protein of bacteria can also be denatured at 100 ℃, and all the disinfection and sterilization items need to be soaked in the water surface. Suitable for small items such as tableware, certain toys, baby bottles and so on.

(4) Natural ultraviolet rays: Natural ultraviolet rays are sunlight, and the sterilization effect cannot be ignored. Suitable for air, clothing, plush toys, bedding, etc.

(5) Air cleanliness: Keep the indoor air clean, frequent ventilation is necessary, especially in autumn and winter, don't neglect the ventilation because of the cold.

(6) 84 Disinfectant: The disinfectant contains chlorine, which can effectively sterilize and sterilize. It can be sterilized and sterilized after being directly diluted in a plastic pot, but you need to avoid food and tableware. Suitable for tables, chairs, beds, walls, floors, etc.




Q3, how to disinfect the surface of objects?

When disinfecting the surface of an object, you can choose the methods of cleaning, wiping, spraying and soaking. Generally, chlorine-based disinfectants, such as 84 disinfectant, 500mg / L are applied to the surface of the object for 10 minutes to basically kill the coronavirus. 75% alcohol can also be wiped and disinfected.




Q4. How to sterilize tableware and items directly imported?

Disinfect tableware, etc. can be boiled in water, boiled and disinfected in water for 15 to 30 minutes can generally kill coronavirus. It can also be disinfected by ultraviolet light for more than 30 minutes to kill coronavirus.




Q5. How to disinfect clothes and bedding?

Clothes and bedding should be washed frequently, exposed to sunlight, and even heated. Many washing machines have the function of heating, disinfection and sterilization.




Q6, common home disinfection

Recently, it has been reported that coronavirus is found on the door handle, so the disinfection of the surface of these items that may be touched daily is very important. Items should be wiped with a chlorine-containing disinfectant containing 250-500 mg / L of available chlorine, and then washed with water; at least once a day. Mobile phones can be wiped and disinfected with medical alcohol.

② Ground surface Wet mopping the floor with 250-500mg / L chlorine disinfectant at least once a day.




Q7. Can edible vinegar for indoor use kill new coronavirus?

No! The concentration of acetic acid contained in edible vinegar is very low, which can not achieve the disinfection effect, and it is easy to cause irritation to human eyes and respiratory tract. Vinegar vinegar prevention method is not reliable.

Q8, how to disinfect public transport

One is to do a good job of surface disinfection. Under normal circumstances, the environment on public transportation should be kept clean and hygienic, and preventive disinfection measures should be taken. After the operation of public transportation such as airplanes, trains, subways, buses, ships, etc., use 250mg / L ~ 500mg / L of available chlorine for the surface of internal objects (such as the inner wall of the body, the steering wheel of the driver, the armrests in the car, tables and chairs, etc.) The chlorine-containing disinfectant can be sprayed or wiped, or it can be wiped with an effective disinfectant wipe. Seat covers and other textiles should be kept clean and washed and disinfected regularly.

When vomiting occurs on public transportation, disinfectants (such as chlorine-containing disinfectants) or disinfecting dry towels should be used to cover and disinfect the vomit. After removing the vomit, the surface of the objects should be disinfected with disinfectants such as Xinjieer.

When there are suspected or confirmed cases, under the guidance of professionals, the contaminants should be completely removed before disinfection; if there are no visible contaminants, 100mg / L of chlorine disinfectant or 500mg / L Wipe or spray disinfect with chlorine dioxide disinfectant. The floor disinfection is sprayed once from the outside to the inside, and the spraying amount is 100ml / m2-300ml / m2. After the indoor disinfection is completed, the spray is repeated once from the inside to the outside. The disinfection time should be no less than 30 minutes.

The second is to strengthen ventilation. Under normal circumstances, natural ventilation or mechanical ventilation can be used. For relatively closed environments such as airplanes, high-speed rails, and subways, it is recommended to appropriately increase the air-conditioning ventilation power to increase the number of ventilations, and pay attention to cleaning and processing the air-conditioning filters regularly; When driving at low speed, you can also open the window for ventilation during the stop to maintain air circulation.

When there is a suspected or confirmed case, under the guidance of professionals, select disinfectants such as peracetic acid, chlorine-containing disinfectants, chlorine dioxide, hydrogen peroxide, etc. under unmanned conditions, and use the ultra-low volume spray method for disinfection.
