Njengesixhobo esitsha esinemisebenzi emininzi, i-magnesium oxide inethemba lokusetyenziswa ngokubanzi kwiinkalo ezininzi, ngokutshatyalaliswa kwendawo ehlala abantu, iibhaktheriya ezintsha kunye neentsholongwane zivela, abantu bafuna ngokukhawuleza izinto ezintsha ezichasene ne-antibacterial, i-nanomagnesium oxide kwintsimi ye-antibacterial. antibacterial show eyakhayo iinzuzo ezizodwa.
Uphando lubonisa ukuba i-concentration ephezulu kunye ne-ion ephezulu ye-oksijini esebenzayo ekhoyo kumphezulu we-nano-magnesium oxide ine-oxidation eyomeleleyo, enokuthi itshabalalise ubume be-peptide bond yodonga lwe-cell membrane yebhaktheriya, ngaloo ndlela ibulala ibhaktheriya ngokukhawuleza.
Ukongezelela, i-nano-magnesium oxide particles inokuvelisa i-adsorption eyonakalisayo, enokuthi itshabalalise i-membrane yeeseli zebhaktheriya. Umatshini onjalo wokulwa neebhaktheriya unokoyisa ukunqongophala kwemitha ye-uv yee-antimicrobial agents zesilivere ezifuna ii-antimicrobials ezicothayo, ezitshintsha umbala kunye ne-titanium dioxide.
Injongo yolu phononongo kuphononongo lwe-nano-magnesium hydroxide elungiselelwe yinkqubo yenqanaba lolwelo lwemvula njengomzimba ohamba phambili, kunye nophononongo lwe-nano-magnesium oxide calcination kwiipropathi ze-antibacterial yi-nano-magnesium hydroxide calcin.
Ukucoceka kwe-magnesium oxide elungiselelwe yile nkqubo inokufikelela ngaphezu kwe-99.6%, ubungakanani be-particle i-avareji ingaphantsi kwe-nanometers ye-40, ubukhulu be-particle busasazwa ngokulinganayo, kulula ukusabalalisa, izinga lokulwa ne-antibacterial ye-E. coli kunye ne-Staphylococcus aureus ifikelela ngaphezu I-99.9%, kwaye inoluhlu olubanzi lwezicelo kwintsimi ye-antibacterial ebanzi.
Izicelo kwintsimi yeengubo
Ngengubo njengomphathi, ngokongeza i-2% -5% ye-nano-magnesium oxide, ukuphucula i-anti-bacterial, i-flame retardant, i-hydrophobic coating.
Izicelo kwintsimi yeeplastiki
Ngokongeza i-nanomagnesium oxide kwiiplastiki, izinga lokulwa ne-antibacterial yeemveliso zeplastiki kunye namandla eplastiki anokuphuculwa.
Ukusetyenziswa kwiikeramics
Ngokutshizwa komphezulu we-ceramic, i-sintered, iphucula i-flatness kunye neempawu ze-antibacterial ze-ceramic surface.
Izicelo kwibala leempahla ezilukiweyo
Ngokongezwa kwe-nanomagnesium oxide kwifayibha yelaphu, i-retardant yomlilo, i-antibacterial, i-hydrophobic kunye nokumelana nokunxiba kwelaphu kunokuphuculwa, okunokusombulula ingxaki yokukhukuliseka kwebhaktiriya kunye nebala. Isetyenziswa kakhulu kwibala lempahla yasemkhosini neyasekuhlaleni.
Ukuqukumbela
Okwangoku, siqale kade kuphando malunga nezixhobo zokulwa nentsholongwane, kodwa kwakhona ukusetyenziswa kophando kunye nophuhliso kusekwinqanaba lokuqala, emva kweYurophu kunye ne-United States kunye neJapan kunye namanye amazwe, i-nano-magnesium oxide ekusebenzeni okugqwesileyo. yeempawu ezilwa ne-antibacterial, iya kuba yinto entsha eyintandokazi ye-antibacterial, kuba izinto ezichasene ne-antibacterial yaseChina kwintsimi yekona yokugqithisa inika into efanelekileyo.
