Nano - titaniyamu woipa amawola mabakiteriya kukwaniritsa antibacterial zotsatira pansi pa zochita za photocatalytic. Chifukwa mawonekedwe amagetsi a nano -titanium dioxide ndi malo amtengo odzaza ndi TIO2 ndi malo opanda kanthu kalozera. M'madzi ndi mpweya, nano-titanium dioxide ili pansi pa dzuwa, makamaka pansi pa cheza cha ultraviolet. Pamene mphamvu yamagetsi ifika kapena kupitirira gulu lake kusiyana Nthawi. Zamagetsi zitha kukokedwa kuchokera kudera lamitengo kupita kumalo owongolera. A angapo zochita zimachitika, amene adsorbed ndi kusungunuka mu mpweya kugwira ma elekitironi kupanga O2 ·. The kwaiye supersonic anion free radicals amapangidwa ndi zambiri organic kanthu zimachitikira (makutidwe ndi okosijeni). Panthawi imodzimodziyo, CO2 ndi H2O zikhoza kupangidwa ndi zinthu zamoyo mu mabakiteriya; pamene ma acupoints adzatengedwa pa OH ndi H2O oxidation ya OH ndi H2O pamtunda wa TIO2 pamwamba mpaka · OH, · OH, yomwe idzakhala ndi mphamvu ya okosijeni yamphamvu. Ma atomu amapanga ma free radicals atsopano, amapangitsa kuti unyolo uchitike, ndipo pamapeto pake amayambitsa kuwonongeka kwa bakiteriya.

Mphamvu ya Sterilization ya TIO2 ili mu kukula kwake kwachulukidwe. Ngakhale titaniyamu pinki ufa (wamba TiO2) imakhalanso ndi photocatalytic zotsatira, imatha kupanganso zamagetsi ndi mabowo. Ndizovuta kusewera zotsatira za antibacterial zotsatira, ndipo TiO2, yomwe imafika pamlingo wa nano -level decentralization, yasamutsidwa kuchoka ku thupi kupita kumtunda. Malingana ngati nthawi ya nanoseconds, picoseconds, ngakhale femllo, gulu la photochemical electronics ndi cavities limakulitsidwa mu nanoseconds. Ikhoza kusuntha mofulumira pamwamba. Menyani tizilombo ta bakiteriya ndikusewera ndi antibacterial effect.

TiO2 imagwiritsidwa ntchito kwambiri muzovala ngati mtundu watsopano wa antibacterial wothandizira
Nano-level TIO2 particles ali ndi mphamvu zowononga antibacterial pansi pa kuwala, ndipo ndi kuwonjezeka kwa antibacterial ndende ndi nthawi yowala, mlingo wa antibacterial ukuwonjezeka, ndipo mphamvu ya antibacterial imalimbikitsidwa kwambiri. Ndi zotheka kuchitira nano -TiO2 pa nsalu ndi njira akuwukha, ndi kukonzedwa nsalu ali antibacterial zoonekeratu, koma zomatira ndi dispersant ayenera kuwonjezeredwa kusintha kuphatikiza kwa TIO2 ndi nsalu. Pambuyo kuwonjezera zomatira ndi dispersing wothandizira, ndi antibacterial wa nsalu ndi zabwino madzi zosagwira ntchito.

Ubwino wa nano - titaniyamu woipa antibacterial: otetezeka ndi sanali poizoni kwa thupi la munthu, palibe mkwiyo kwa khungu; mphamvu antibacterial wamphamvu, osiyanasiyana antibacterial osiyanasiyana; palibe fungo,; kukana madzi kwautali, nthawi yayitali yosungira; kukhazikika kwabwino kwa kutentha, kusasintha kwa mtundu pa kutentha kwakukulu, palibe kuwonongeka, mosasamala kanthu za kuwonongeka, mosasamala kanthu za kuwonongeka, mosasamala kanthu za kuwonongeka. Musagwedezeke, musawonongeke; kusakhazikika bwino.
