Kufotokozera:
Ntchito zazikuluufa wa nano Ag:
1. Antibacterial: lipoti la mayeso a Ag dispersion likupezeka
Njira ya antibacterial ya nano silver powder nthawi zambiri imakhala ndi izi:
1.1.The pamwamba catalysis wa nanopowder siliva zimakhudza yachibadwa kagayidwe ndi kuberekana mabakiteriya, kuchititsa imfa ya mabakiteriya.
1.2.Zosakaniza zogwira ntchito mu antibacterial fiber zimagwira ntchito pama protein membrane a cell.Itha kuwononga mwachindunji nembanemba ya cell ya bakiteriya ndikupangitsa kuti zomwe zili mu cell zizituluka.Nano Ag ndi adsorbed pa nembanemba selo, amene amalepheretsa mabakiteriya ndi tizilombo tina kuyamwa amino zidulo, uracil ndi zakudya zina zofunika kukula, potero kulepheretsa kukula kwawo.
1.3.Kutalikirana kwa infuraredi kunyezimira komwe kumapangidwa kuchokera pamwamba pa nsalu ya antibacterial yokhala ndi Ag nanoparticle kumakhala ndi mawonekedwe amtundu wina, womwe ungalepheretse ntchito ya mabakiteriya ndikupangitsa kufa kwawo.
2. Chothandizira: tinthu tating'onoting'ono ta siliva titha kusintha kwambiri liwiro komanso mphamvu yamankhwala.
3. Phala lapamwamba: phala lophatikizika, inki yopangira, zida zatsopano zomangira nano phala lasiliva, ndi zina.
Malingaliro ena amomwe mungapangire nano Ag kubalalitsidwa:
Ponena za kubalalitsidwa kwa nano siliva ufa, nthawi zambiri akulimbikitsidwa kuwonjezera surfactant yoyenera pamodzi ndi makina kubalalitsidwa njira kukwaniritsa bwino kubalalitsidwa.Mphero ya jet ya supersonic itha kugwiritsidwa ntchito kutsitsa ndikusintha pamwamba pa ufa wa siliva wouma.Kusinthidwa komwe kumagwiritsidwa ntchito kwambiri kumaphatikizapo: PVP, oleic acid yokutidwa siliva nano ufa, etc.
Mkhalidwe Wosungira:
Silver nanoparticle iyenera kusungidwa pamalo ozizira komanso owuma.
