1. Which disinfectants are effective against coronavirus?

Coronavirus is sensitive to common disinfectants. Among the various disinfectants, 75% alcohol, 84 disinfectant (sodium hypochlorite), chlorine dioxide, Compound Potassium Peroxymonosulphate, glutaraldehyde, povidone iodine and peroxyacetic acidcan effectively inhibit or kill the coronavirus.

However, the disinfectants of cationic surfactants have poor effect on the coronavirus, such as chlorhexidine, Bromogeramine,centoxic, etc.

3. Which disinfectants or disinfection spray is suitable for air in public places?

There are various ways to sanitizing the air in public places, including :

·Ventilation

·Install the central air conditioning ventilation system air disinfection device.

·Spray disinfection

Peroxyacetic acid or hydrogen peroxide are commonly used the disinfectant spray for air.

The concentration of peracetic acid is 0.2%-0.5%, and the dosage is 8ml/m³. After spraying, space needs to be sealed for 30 mins.

The concentration of hydrogen peroxide is 3%, and the dosage is 30ml/m³. After spraying, the space needs to be sealed for 60 mins.

In the process of spray disinfection, you will need to leave the scene,or make personal protection and leave the scene immediately after the spray operation.

·Fumigation

In this method ,3% Peracetic acid is used to fumigate in a closed room with a dosage of 30ml/m³, and the disinfection requirements can be achieved after 60 minutes of action.

As Peracetic acid has certain bleaching and corrosion effects, so

you will need to pay attention to the safety of indoor articles and electrical appliances when fumigating,and cannot be present.

After fumigation, open the door and open the window, and enter the site after the peracetic acid in the air has dissipated.

·UV lamp disinfection

·Electrostatic adsorption purification sterilizer

 

4. Which disinfectants or disinfection spray is suitable for passager in public places?

smart disinfection tunnel.jpg

With the returning to work and production tide,a new disinfection spray gateway at many public places has come into your eyes,called disinfection tunnel.

 

When you pass through the disinfection tunnel, the nozzle will spray a disinfection mist for you to wash your hands or to your whole body, and all surfaces of passing by are possibly sanitized but not directly exposed to the nozzle.

The disinfection tunnel adopts compound potassium peroxymonosulphate powder mixing with water to realize the antibacterial spray.

You can see its working principle as follows:

After dissolving in water, compound Potassium Peroxymonosulphate continuously produces hypochlorite, hydrogen ion, new ecological oxygen, sulfuric acid-free radical, hydroxyl free radical and other active substances through a chain reaction, oxidizes and chlorinates pathogens, penetrates the envelope structure of the enveloped virus, interferes the synthesis of DNA and RNA of pathogens, coagulates and denatures the proteins of pathogens, and then interferes the activity of pathogen enzyme system and affects its activity Metabolism, increase the permeability of cell membrane, cause the loss of enzymes and nutrients, pathogen dissolution and rupture, and then quickly and effectively kill pathogens.

Besides, potassium peroxymonosulphate is a compound disinfectant. The disinfectants containing chlorine, iodine, aldehydes, phenols, biological extracts (essential oil), quaternary amines (benzalkonium bromide, benzalkonium chloride) and metals (silver sulfate, silver nitrate) are all single side disinfectants.

But also potassium peroxymonosulphate produces H and acid, that will do double disinfection. And the chlorine and chlorine oxide,can sanitizing the halogen . And through the release of oxygen free radicals, it plays the role of oxidant.

Whereby,oxygen-free radical is the most active component in the potassium peroxymonosulphate, but also the most important part.

Last, a chain reaction takes place to oxidize sodium chloride into chlorine and decompose it into hypochlorite.

Moreover, there is no residue from potassium peroxymonosulphate . and no injurious and abnormal effect on people and animals.


5. What are the household disinfectants?

75% of ethanol (medical alcohol)

75% of alcohol has a good effect of anti-virus, less irritant and corrosive, and can be used for hand and skin disinfection, as well as disinfection of small object surface.

It is recommended to buy small bottles of alcohol (< 500ml) for home use. You can use it to make your DIY disinfectant spray. When used, the alcohol solution can be installed in a small spray bottle, and cotton balls or gauze can be used to make alcohol cotton balls and cotton yarns to wipe.

You need to pay attention to the following aspects:

1. Avoid physical contact with alcohol.

2. When the household uses alcohol to disinfect the surface of electrical appliances, remember to cut off the power supply, and all articles can be reused only after the alcohol volatilizes.

3. It should not be used for large area disinfection and air disinfection.

4. It is not recommended to use with 84 disinfectant at the same time, the disinfection effect will be weakened or even gas may be produced.

5. Proper storage: alcohol belongs to inflammable dangerous goods, which should not be stored in large quantities at home, generally no more than 500ml, far away from the heat source environment, stored in a cool place, and pay attention to ventilation when using.


Chlorine containing disinfectant

Commonly homemade disinfectants including bleaching powder, bleaching water, 84 disinfectant, chlorine-containing disinfectant or effervescent tablets, etc., which can be soaked, sprayed, wiped and other ways of use.

You will use this disinfectant mainly for the surface and environmental disinfection.

When disinfecting the surface of the object, use the concentration of 500mg / L; when there are obvious pollutants, use the concentration of 2000mg / L. When it is used for soaking disinfection, the soaking time is 10-30 minutes, and then rinse with water.


You need to pay attention to the following aspects:

1. These disinfectants are obviously irritant and corrosive, so masks and gloves should be worn when they are used; if they are accidentally splashed into the eyes, they should be washed with water immediately, and those who are serious should be hospitalized.

2. It is prepared in cold water. Different concentrations are prepared according to different sanitizing purposes.

3. It can corrode metal, bleach, and fade the fabric.

4. Do not contact with inflammable, keep away from fire source; use in a well-ventilated area.

5.84 it is strictly prohibited to mix disinfectant with acid substances (such as vinegar, toilet cleaner, alcohol, etc.), which will produce a large amount of chlorine gas after mixing, resulting in personnel poisoning.


Chlorine dioxide

You can use chlorine dioxide to sanitize the surface of objects. The concentration of chlorine dioxide is usually 50mg / L to 100mg / L, and the effect is 10 to 15 minutes.

You need to pay attention to the following aspects:

1. Chlorine dioxide is highly corrosive, irritating to eyes, mucous membranes, and skin, and dangerous to burn. Masks and gloves should be worn when using it. In case of inadvertent contact, a large amount of water should be used for washing and timely medical treatment.

2. Chlorine dioxide is a kind of inflammable and explosive dangerous goods, which will cause combustion and explosion in case of opening the fire and high heat. It must be kept away from the heat source and stored in a cool and ventilated place.

6. In addition to the use of disinfectants, what other sanitizing measures?

As the coronavirus is sensitive to UV and heat, so UV sanitizer and physical heating are also the methods you can use for home disinfection.


UV sanitizer

Some families may also be equipped with disinfection cabinets (UV lamps), and some chronic patients (peritoneal dialysis patients) have UV lamps at home, which can be used for air and object surface disinfection.

You will need to take note:

1. The UV penetration is poor, it directly irradiates the surface of the object, so it is only suitable for the surface disinfection of the object.

2. UV can damage human skin and cornea. Therefore, you will need to close the doors and windows during indoor sanitizing and avoid it. The exposure time should not be less than 30 minutes. After disinfection, the room should be fully ventilated.


Physical heating (30 minutes above 56 ℃)

The disinfection method of physical heating is convenient and safe, so it can be widely used for the disinfection of various heat-resistant items such as clothes, tableware, toys, milk bottles, and other small items.

When washing, you can choose a washing machine with the function of heating and washing (above 56 ℃), or choose a dryer to dry the clothes.

You need to note: for the new coronavirus, the temperature should be at least 56 ℃, and the disinfection time should be at least 30 minutes to ensure that the virus is fully inactivated.

6.Conclusion

From above all kinds of disinfectants or disinfection spray, I would like to conclude that not all kinds of sanitizing products can kill coronavirus or not all disinfection methods are effectively to kill the virus.

Whereby,what I would like to recommend is the Compound Potassium  Peroxymonosulphate ,a safety and healthy disinfectant the same as the bleach in the tap water we drink every day, or the best detergent we used to clean our fruits and melons.

And it was widely used as lysol disinfectant spray in products of public value disinfection tunnel for more public safety protection.

 

Last I would like to say:

 

Scientific understanding disinfectants

 

Scientific proportioning and application

 

There's no need to panic

 

You can't be careless

 

Fight a good epidemic prevention and interdiction war

 

We fight with you
