PVC Ntim Zaj duab xis Classification

Antibacterial Mechanism: Photocatalytic antibacterial agents feem ntau yog TiO2. Nyob rau hauv lub teeb, ib tug loj tus naj npawb ntawm hydroxyl thiab oxygen radicals yog tsim nyob rau saum npoo. Ob lub radicals no muaj cov tshuaj lom neeg muaj zog thiab tuaj yeem ua rau cov organic decomposition ntawm ntau yam kab mob, yog li nthuav tawm cov tshuaj tua kab mob.

Daim ntawv thov ntawm Photocatalytic Inorganic Antibacterial Agent Films: Txij li thaum thawj lub lag luam tawm ntawm photocatalytic cov neeg ua haujlwm hauv Nyij Pooj xyoo 1995, thaj chaw thov dav dav tau ntim khoom noj.

Lwm cov yeeb yaj kiab tshuaj tua kab mob muaj xws li cov tshuaj tua kab mob ntuj thiab cov tshuaj tua kab mob polymeric. Lawv cov txheej txheem tiv thaiv kab mob cuam tshuam nrog kev sib cuam tshuam ntawm tus nqi ntawm cov saw hlau molecular nrog cov kab mob, yog li inhibiting microbial reproduction thiab ua tiav cov tshuaj tua kab mob. Chitosan, sorbic acid, thiab curcuminol feem ntau yog siv rau hauv ntim khoom noj.

Cov teebmeem ntawm cov tshuaj tiv thaiv kab mob sib xyaw ua yeeb yaj kiab feem ntau yog tshwm sim hauv cov hauv qab no: txuas ntxiv lub sijhawm tshuaj tua kab mob; ua antibacterial thaj chaw ntawm tsawg concentration; Kev nthuav dav cov kab mob tua kab mob, inhibiting ntau cov kab mob ntau dua li ib qho yeeb yaj kiab tshuaj tua kab mob.

Inorganic antibacterial agents yog cov tshuaj tua kab mob uas ua los ntawm cov kab mob bactericidal thiab bacteriostatic ntawm cov hlau xws li nyiaj, tooj liab, zinc, thiab titanium thiab lawv cov ions. Thaum xyoo 1980s, cov kws tshawb fawb Nyij Pooj tau pib ncaj qha ntxiv cov nyiaj sib txuas rau cov resins, tsim thawj cov kab mob yas yas siv cov tshuaj tua kab mob inorganic. Antibacterial Mechanism: Vim tias inorganic antibacterial agents yog leaching tiv tauj hom tshuaj tua kab mob, cov nyhuv antibacterial ntawm inorganic antibacterial agent films yog passive. Muaj ob txoj kev piav qhia rau cov kab mob tua kab mob ntawm cov hlau ions: Ib qho yog cov tshuaj tiv thaiv kev sib cuag. Thaum cov hlau ions nyob rau hauv cov yeeb yaj kiab inorganic antibacterial neeg sawv cev tuaj rau hauv kev sib cuag nrog cov kab mob, lawv rhuav tshem cov qauv protein ntawm cov kab mob, ua rau microbial tuag lossis ua haujlwm tsis zoo. Lwm qhov yog reactive oxygen hom mechanism. Cov micro-hlau ions faib rau ntawm qhov chaw ntawm cov tshuaj tua kab mob inorganic zaj duab xis tuaj yeem nqus tau lub zog los ntawm ib puag ncig, ua kom cov pa oxygen adsorbed hauv huab cua thiab dej rau saum npoo ntawm lub ntim zaj duab xis, tsim cov hydroxyl radicals thiab cov pa oxygen reactive. Cov no muaj peev xwm redox muaj zog, uas tuaj yeem rhuav tshem lub peev xwm ntawm cov kab mob, inhibit lossis tua cov kab mob, thiab tsim cov nyhuv antibacterial.
