| Abstract: | Multiaperture silver-carrying silicon dioxide antibacterial agents are made out of sodium silicate material. Experiment results show that the antibacterial effect is related to the technology of supporting formulation. The preferable effect of the alkaline processing is as good as 97.5%. The suitable conditions for supporting formulation and its silver containing, which are obtained by the orthogonal experiment approach, are as follows： Na2CO3 mass=5g, ethanol quantity=1ml, reaction temperatures=70.0 ＆ 45℃, AgNO3 concentration=0.3mol/L, and reaction time= 16h.The average bactericidal rate is as high as 97.8 %. |
