As we all know, the current common sterilization methods mainly include ozone micro sterilization, formaldehyde sterilization, ultraviolet radiation sterilization, etc. The above sterilization methods have been used in various occasions, but the traditional sterilization methods have fatal shortcomings in practical application. In order to solve the problems brought by the traditional sterilization methods, such as poor sterilization effect, high corrosivity and harm to human body and environment, hydrogen peroxide sterilization came into being.
Hydrogen peroxide (H2O2) is a naturally occurring chemical substance, which widely exists in air and water. As early as the 18th century, human beings discovered and began to use hydrogen peroxide, which is widely used in food, beverages, medical equipment and medical care. The sterilization principle is that the oxygen (O -) in hydrogen peroxide exists in the form of high energy state, which is very unstable and can be decomposed and reduced to oxygen (O2) at any time under normal temperature. During the reduction of hydrogen peroxide, oxygen atoms will be separated, and at this time, oxygen atoms have strong oxidation and decomposition capabilities. It can quickly penetrate the cell membrane of bacteria and react irreversibly with it to kill bacteria. It can also react with the viral envelope to oxidize and quickly kill viruses. When oxygen atoms encounter organic or inorganic substances, oxidation will occur to remove organic pollutants and odor in the air, generate non-toxic substances, and decompose into oxygen and water after disinfection. It has a good killing effect on many microorganisms such as Escherichia coli, Salmonella, Staphylococcus aureus, Staphylococcus albus, poliovirus and fungi. The use of hydrogen peroxide mainly depends on the degree of oxidation, and different concentrations of hydrogen peroxide have different uses.
Since the outbreak of the epidemic, the disinfection quality of hospitals, emergency centers, PCR laboratories and other places has been greatly challenged, and it is urgent to improve the standard of space sterilization. The biggest characteristic of hydrogen peroxide sterilization is to use low concentration of disinfectant to achieve a high level of disinfection effect, and it will not produce corrosivity to articles in the environment. Although some domestic brands also use low concentration disinfectants, most of them are difficult to meet the sterilization requirements, so they will add peracetic acid or acetic acid synergist or increase the dose of disinfectant in the unit sterilization space to achieve the goal, which will bring irreversible impact on the environment.
Ofim hydrogen peroxide sterilization principle is to use the unique characteristics of hydrogen peroxide dry fog that makes irregular movement in the air, does not settle, and cannot polymerize to produce large droplets, which will rebound and do not break after contact with it. The smaller the hydrogen peroxide dry fog particles, the longer the suspension time in the air, and the better the disinfection effect, The use of Ofim hydrogen peroxide for sterilization has the advantages of good diffusion and non corrosion of color steel plate and equipment. Oxfam hydrogen peroxide sterilization has very strong bactericidal ability and does not contain acetic acid and peracetic acid, which can kill the spores of black withered grass to the 6th power of 10; It can kill more than 200 kinds of microorganisms including Gram bacteria, fungi, mycoplasma, viruses, superbacteria, etc., including Acinetobacter baumannii, MRSA, MREA, Clostridium difficile and other common drug-resistant bacteria; It is convenient to move in each ward and environment, and is extremely convenient to use; The risk of corrosion to the environment is almost equal to 0; The residue is less than 1ppM, which complies with OSHA requirements and is harmless to human health, and can provide test reports of all the above bactericidal species.
