Why gaseous hydrogen peroxide is better than fogging ?
Recently, we are frequently asked why gaseous hydrogen peroxide is better than fog ?
Firstly we need to know a basic concept :
hydrogen peroxide fog is liquid particle, eventough the particles can be small to micron size , but all the chemical and physical properties are the same as liquid phase .
Gaseous hydrogen peroxide is a mist of gas and atomized particles , so the chemical properties contain not only liquid but also gas chemical and physical properties .
So what is the advantages of vapour phase of hydrogen peroxide ?
Stronger disinfecting ability
The disinfection efficiency of gaseous plasma hydrogen peroxide is much higher than that of liquid hydrogen peroxide, which can achieve ultra-broad-spectrum disinfection. At present, almost all the known microorganisms including prion and spore can be killed by gaseous plasma hydrogen peroxide . But liquid hydrogen peroxide is ineffective against prions. The pathogens in the indoor environment are diverse. We cannot determine what pathogenic microorganisms are present before killing, so we cannot carry out targeted disinfecting, but can only disinfect all of them. Therefore, broad-spectrum and disinfecting ability become very important.
Since the disinfecting efficiency of gaseous plasma hydrogen peroxide is much higher than that of liquid hydrogen peroxide, the consumption of cubic meters for the same level of biological reduction is much lower than that of liquid hydrogen peroxide, achieving 99.9999% of the standard of killing Bacillus stearothermophilus, Each cubic meter requires 6-10ml of 7.5% hydrogen peroxide solution, and liquid requires more than 15ml .
No dead angles
According to scientific surveys, traditional wiping disinfection can cover up to 70% of the surface of the indoor space. This data has not taken into account the larger area of ‘unkilled’ surfaces caused by the human mistake. We understand this data with common sense: hand-operated wiping cannot reach hard-to-reach corners and high spots.
Regarding the fogging system , the small particles will sink due to gravity and eventually adhere to the surface of the object to achieve disinfection. However, no matter how small it is, it is still liquid particles. Increasing the spray velocity will also cause condensation on the roof, and a large amount of mist will again aggregate into water.
But the we spray gas , we can cover everywhere, overcoming obstacles and spreading evenly into every corner of the space like air!
Bigger space, smaller body
Imagine that we blow rocks, water and air with the same amount of wind , which one will blow farther? Under the same aerodynamic force, gaseous hydrogen peroxide can be blown farther. The same aerodynamics means the same size of the aerodynamic system, which means that the gaseous hydrogen peroxide equipment can be made smaller under the same processing space.
