Abstract:
More than 99.9% of Escherichia Coli,Staphylococcus Aureus and HBsAg on the surface of the haircutting appliance could be killed or inactivated in the box with two Ultraviolet-rays lamps for 10 minutes,but the killing rates did not reach the levelof 99.9% when the haircutting appliance was exposed for 5 minutes.If the disinfecting box was set with only one lamp and covered with reflecting material,more than 99% of the bacteria on the side of haircutting appliance back to the light was killed by the reflecting light for 10 minutes.Even after shining for 20 minutes,the killing rate was still less than 99.9%,which did not meet the criterion of killing bacteria.
