Silver Nanoparticles Usages

Iyo yakawanda kwazvosirivheri nanoparticlesinoshandiswa ndeye anti-bacterial uye anti-virus, zvakasiyana-siyana zvinowedzera mumapepa, mapurasitiki, machira e-anti-bacterial anti-virus.About 0.1% ye nano layered nano-silver inorganic antibacterial powder ine inhibition yakasimba uye inouraya pa escherichia coli, staphylococcus aureus nemamwe akawanda epathogenic microorganism.Sechigadzirwa chitsva chekurwisa hutachiona, chine hupamhi hwakakura, hapana kurwisa kwemishonga, haikanganisike nePH kukosha uye antibacterial yakasimba, haisi nyore kuve oxided, zvichingodaro.Silver nanoparticles is zvakabudirira kushandiswa mukuvaka, kuchengetedzwa kwetsika dzetsika, zvigadzirwa zvekurapa.

Silver nanoparticles antibacterial mechanism inonyanya kuve neanotevera akati wandei maficha:

1. iyo inobudirira midziyo ye antibacterial fiber effect pa cell membrane proteins.Inogona kuparadza zvakananga bacteria cell membrane, inokonzera sero zvinyorwa zvinoputika.Sirivha nanoparticles yakashongedzwa pane cell membrane kuvhara mabhakitiriya uye humwe hutachiona kukura, kureva, nano sirivheri inogona kumisa mabhakitiriya kuti atore zvakakosha senge amino acid, uracil, nekudaro ichitadzisa kukura kwayo.

2. antibacterial machira pamusoro anoburitsa imwe wavelength kureba kwere infrared ray, iyo inotadzisa kuita kwebhakitiriya, ichiuraya mabhakitiriya.

3. pamusoro catalytic mhedzisiro yesirivheri nanoparticles, inokanganisa yakajairwa metabolism yebhakitiriya uye kuberekesa kwakajairika kuuraya mabhakitiriya.

Kupararira kwesirivha nanoparticles kunowanzokurudzirwa kuti kuwedzera ma surfactants uye mechanical dispersion method inobatanidza, ichaita kuti iwedzere kupararira. Unogona kushandisa supersonic jet chigayo depolymerize uye kugadziriswa kwepamusoro kune sirivheri nanoparticles powder.Kushandura kwedu kunonyanya kushandiswa kwepamusoro kunosanganisira PVP, oleic acid, etc.
