The researches exhibit that the magnesium oxide is uncomplicated to hydration, and variety a layer of magnesium hydrate. The oxygen in the remedy can deliver the reactive oxygen species via the reduction response of solitary electron. There is a layer of hydroxyl ion on the surface of magnesium oxide. Owing to the oxygen fuel has chemical balance in alkaline atmosphere, the reactive oxygen species with higher focus can exist on the magnesium oxide area. And the reactive oxygen species has robust oxidability, it can destroy the peptide bond framework of the mobile walls of the microbes. For that reason, it can kill microbes quickly. nnIn addition, the nano magnesia particle can develop harmful adsorption, and also can harm the cell walls of the microorganisms. This sort of antibacterial mechanism can triumph over the defects: ag-variety antibacterial agent is gradual and easy to discolor. ZnO-TiO2 antibacterial agent require the ultraviolet irradiation. nnAt current, there are two approaches to exploit magnesium oxide antibacterial product:
nnIn the very first location, in buy to increase the mildew resistance of nano magnesium oxide, it need to controlling the particle dimensions and morphology options. For illustration, the scientist has previously succeed in studying and producing a sort of flaky nano magneisum oxide powder. It expresses effective antibacterial, antiseptic qualities
for the anthrax, staphylococcus, escherichia coli and many others. nnIn the 2nd put, exploiting the novel compound via recombining the magnesium oxide and other antibacterial supplies. There are some main antibacterial materials: activated carbon and magnesium oxide, metallic oxide, magnesium oxide and chlorine, bromine gas and magnesium oxide, etcetera. The nano magnesia powder were distributed evenly on the activated carbon matrix. For the staphylococcus aureus, it has superb antibacterial residence. nnThe chlorine and bromine gasoline in the halogen factor is solid bactericide
. Nonetheless, the large vapor force with poison won't be able to be made use of by itself. It can variety a steady gasoline program of magnesium oxide and halogen factor as a result of making use of the magnesia's robust adsorption. So, we can use it safely and efficiently. nnIn the factor of metallic oxide recombination and antibacterial agent, the magnesium oxide and titanium dioxide composite powder can be geared up by codeposition technique, and then, researching its antibacterial system. Below the UV-mild, the titanium dioxide can crank out electrons and holes by photocatalysis. Having said that, it is effortless to composite, and loose photocatalysis and mold resistance. On the area of electronic shell, magnesia exists the blemish, and THPS biocide
can settle for electron and hole. Therefore, it inhibits the recombination amongst electron and gap, raise the photocatalytic performance and enhance the mould resistance. nnIn the generation follow, the nano magnesium oxide plays an important function in creating quite a few antibacterial elements, such as the antibacterial ceramics, antibacterial plastics and so on. nnHebei Meishen Technology Co., Ltd is the specialist magnesium oxide supplier and manufacturer.
