Action principle of the present invention:
The plasma that the present invention adopts is a kind of ionized gas, belongs to the low temperature plasma field, during work under an atmospheric pressure environment temperature near room temperature.Plasma electrical source produces the medium-high frequency high voltage, act on the plasma generating electrodes, the generation plasma also acts in the material barrel, material in the material barrel is subject to the highfield effect in plasma environment, so that the neutral gas molecule in the material barrel produces continuously ionization, form state of matter electronegative and that the ion equivalence zone positive charge coexists mutually, when ionization rate and recombination rate balance, form plasma state, after plasma state occurring in the material barrel, molecule and atom are not only arranged, also has a large amount of charged particles, the energy that its charged particle has is approximately from several eV to several thousand eV, and the moisture in the material and air molecule produce a large amount of hydroxyl free radical HO in plasma environment, hydroperoxyl radical HO
2, active oxygen atom O
3, activation hydrogen atom H isoreactivity composition and abundant ultraviolet ray, thereby greatly improved stress efficacy with microprotein and nucleic acid substances, can within the extremely short time, make microbial death, reach the innoxious purpose of material.Its sterilization functions mechanism mainly comprises following three aspects:: (1) active group effect: the compositions such as a large amount of active oxygen ions that contain in the plasma, the free group of high energy, very easily with bacterium, mould and gemma, virus in protein and nucleic acid substances generation oxidation reaction and sex change, a large amount of active oxygen ions have decomposed the necessary enzyme of the inner glucose of bacterium; Also can be directly and bacterium, virus have an effect, destroy its cell membrane and ribonucleic acid, the macromolecule polyalcohols such as decomposing D NA, RNA, protein, lipid and polysaccharide, be penetrated into the after birth tissue, the inside lipopolysaccharides that enters in the cell membrane reacts in outer membrane lipoprotein, and the distortion of bacterium generation permeability causes cytolysis death.Utilize a large amount of active oxygen ions can destroy the molecular structure that produces stink substance, the stink that decomposing organic pollutant produces in corruption is decomposed.(2) high-velocity particles breakdown effects: the electronics of kinetic energy and ion produce and puncture bacterium thalline and viral phenomenon.(3) ultraviolet effect: in forming the process of plasma, be attended by ultraviolet ray and produce, (3.3～3.6eV) are absorbed by protein in microorganism or the virus this high energy ultraviolet photon, cause its molecule degeneration inactivation.
Research work shows: experimental selection Escherichia coli and bacillus subtilis are the experiment bacterial strain, selecting negative corona to carry out discharge parameter studies under the negative corona condition the impact of sterilization effect, sterilization rate raises with the rising of discharge voltage, in pole plate arcing distance 2cm, discharge time when being 10min, Escherichia coli, the sterilization rate of bacillus subtilis when 20Khz, 13.5kV are respectively 95%, 86%, when voltage is elevated to 20kV, action time, the sterilization rate of two kinds of bacteriums all reached 100% during 5min.All qualified through the monitoring of 20 multiple chemical indicating cards; Be asepsis growth through more than 20 biological indicator monitorings; Article after 20 sterilizations are carried out the equal asepsis growth of Bacteria Culture.That material after the plasma treatment did not all occur in 15 days is mouldy, rotten, fermentation, the phenomenon such as smelly.
