Tlhaloso:
Lisebelisoa tse ka sehloohongphofo ea nano Ag:
1. Antibacterial: tlaleho ea tlhahlobo ea Ag dispersion e teng
Mochine oa antibacterial oa nano silver powder ka kakaretso o na le lintlha tse latelang:
1.1.Tšebeliso ea bokaholimo ba li-nanopowder tsa silevera e ama metabolism e tloaelehileng le ho ikatisa ha libaktheria, ho baka lefu la libaktheria.
1.2.Lisebelisoa tse sebetsang ka har'a likhoele tsa antibacteria li sebetsa ho liprotheine tsa membrane ea lisele.E ka senya ka ho toba lera la sele ea baktheria 'me ea etsa hore likahare tsa lisele li tsoe.Nano Ag e adsorbed holim'a lera la sele, e thibelang libaktheria le likokoana-hloko tse ling ho monya li-amino acid, uracil le limatlafatsi tse ling tse hlokahalang bakeng sa khōlo, kahoo li thibela kholo ea tsona.
1.3.Mahlaseli a hole a infrared a tsoang ka holim'a lesela la antibacteria le Ag nanoparticle a na le leqhubu le itseng, le ka thibelang ts'ebetso ea libaktheria mme la baka lefu la tsona.
2. Catalyst: likaroloana tsa nano tsa silevera li ka ntlafatsa haholo lebelo le katleho ea lik'hemik'hale tsa lik'hemik'hale.
3. Peista ea maemo a holimo: peista e nang le motsoako o kopanyang, enke e tsamaisang, lisebelisoa tse ncha tsa nano bonding nano paste ea silevera, joalo-joalo.
Mehopolo e meng ea ho etsa hore nano Ag e hasane:
Mabapi le ho hasana ha phofshoana ea silevera ea nano, hangata ho kgothaletswa ho eketsa surfactant e loketseng e kopantsoeng le mekhoa ea ho hasana ea mechine ho finyella ho hasana hantle.Leloala la jet la supersonic le ka sebelisoa ho theola le ho fetola holim'a phofo e omisitsoeng ea silevera.Phetoho e sebelisoang ka ho fetesisa ea bokaholimo e kenyelletsa: PVP, oleic acid e tlotsitsoeng ka silevera ea nano phofo, jj.
Boemo ba polokelo:
Nanoparticle ea silevera e lokela ho bolokoa sebakeng se phodileng le se omileng.
