Nano -titanium dioxide inoparadza mabhakitiriya kuti iwane antibacterial madhara pasi pekuita kwe photocatalytic. Nekuti iyo yemagetsi chimiro che nano -titanium dioxide inzvimbo yemutengo izere neTIO2 uye isina chinhu chinotungamira nzvimbo. Mumvura nemhepo, nano-titanium dioxide iri pasi pezuva, kunyanya pasi pemirairo ye ultraviolet. Apo simba remagetsi rinosvika kana kudarika bhendi rayo nguva. Zvemagetsi zvinogona kusimudzirwa kubva kunzvimbo yemutengo kuenda kunzvimbo yekutungamira. Mutsara wekuita kunoitika, iyo inoshambadzirwa uye yakanyungudika muokisijeni kutora maerekitironi kuti aumbe O2 ·. Iyo inogadzirwa supersonic anion yemahara radicals inogadzirwa neakawanda organic matter reactions (oxidation). Panguva imwecheteyo, CO2 neH2O inogona kugadzirwa nezvinhu zvehupenyu mubhakitiriya; nepo acupoints ichabatwa paOH uye H2O oxidation yeOH neH2O pamusoro peTIO2 pamusoro kusvika · OH, · OH, iyo ichava nekukwanisa kwakasimba oxidation. Maatomu anoburitsa mahara radicals matsva, anokurudzira kuita kwecheni, uye pakupedzisira akonzeresa kuparara kwebhakitiriya.

Iyo sterilization mhedzisiro yeTIO2 iri mune yayo quantum saizi maitiro. Kunyangwe titanium pink poda (yakajairika TiO2) zvakare ine photocatalytic mhedzisiro, inogona zvakare kugadzira zvemagetsi nemakomba. Zvakaoma kutamba mhedzisiro yeantibacterial mhedzisiro, uye TiO2, iyo inosvika pachiyero che nano -level decentralization, yakatamiswa kubva mumuviri kuenda kumusoro. Chero bedzi nguva ye nanoseconds, picoseconds, uye kunyange femllo, iyo inoumbwa ye photochemical electronics uye cavities inokudzwa mu nanoseconds. Inogona kukurumidza kuenda kumusoro. Kurwisa mabhakitiriya zvipenyu uye tamba inowirirana antibacterial effect.

TiO2 inoshandiswa zvakanyanya mumachira semhando nyowani ye inorganic antibacterial agent
Iyo nano -level TIO2 particles ine yakasimba antibacterial properties pasi pechiedza, uye nekuwedzera kwehutachiona hwehutachiona uye nguva yechiedza, iyo antibacterial rate inowedzera, uye antibacterial effect inosimbiswa zvikuru. Zvinokwanisika kurapa nano -TiO2 pamucheka nenzira yekunyura, uye jira rakagadziriswa rine antibacterial iri pachena, asi iyo inonamatira uye inoparadzanisa inoda kuwedzerwa kuvandudza kusanganiswa kweTIO2 nemucheka. Mushure mekuwedzera maadhesive uye dispersing agents, antibacterial yemucheka ine yakanaka inodzivirira mvura.

Zvakanakira nano -titanium dioxide antibacterial: yakachengeteka uye isina-chepfu kumuviri wemunhu, hapana kutsamwa kune ganda; simba rinopesana nehutachiona, huwandu hwakawanda hwehutachiona hwehutachiona; hapana hwema,; kureba kwemvura, nguva refu yekuchengetedza; kugadzikana kwakanaka kwekushisa, kusingashanduki kwemavara pakupisa kwepamusoro, kusina kuora, pasinei nekuparara, pasinei nekuparara, pasinei nekuparara, pasinei nekuparara. Usaputsika, usaora; kusagadzikana kwakanaka.
