Ultrasonic cooperative nano-silver washing and sterilizing method

Abstract

The invention relates to the technical field of washing and sterilizing, and discloses an ultrasonic cooperative nano-silver washing and sterilizing method which adopts an ultrasonic cleaner, a visible spectrophotometer and a nano-silver washing agent. The ultrasonic cooperative nano-silver washing and sterilizing method is characterized in that the nano-sliver washing agent is added into the ultrasonic cleaner, and a to-be-cleaned object is added into the nano-sliver washing agent under an ultrasonic state to perform sterilization and disinfection of the object. The nano-silver washing agentdisclosed by the invention has good antibacterial sterilizing effect, is free of any drug resistance, is good in sterilization effect, can kill various germs within several minutes, is strong in permeability, has good sterilizing effect on common bacteria, stubborn bacteria, drug-resistant bacteria, funguses and the like; meanwhile, a layer of protective film is arranged outside the nano-silver washing agent, so that steric hindrance effect is also achieved, and therefore, nano-silver particles can be stably dispersed in a water phase, and the antibacterial effect is lasting; and the ultrasonic cooperative nano-silver washing and sterilizing method is matched with oscillating sterilizing of the ultrasonic cleaner, so that the cleaning and sterilizing effect of a workpiece is better.

Description

technical field [0001] The invention relates to the technical field of washing and sterilization, in particular to a method for washing and sterilizing nano-silver in cooperation with ultrasonic waves. Background technique [0002] The current sterilization technology is still not perfect. Thermal sterilization, such as high temperature and high pressure sterilization, is too strong, which may damage the nature of the product itself. With the development of ultrasonic technology, ultrasonic sterilization has attracted more and more attention. [0003] As we all know, in the process of ultrasonic cleaning and sterilization, in the cleaning liquid, when the ultrasonic intensity exceeds a certain cavitation threshold, cavitation will occur, that is, the tiny bubble nuclei (gas or bubble nuclei) in the liquid will be activated under the action of ultrasound. , which is manifested as a series of dynamic processes such as oscillation, growth, shrinkage and collapse of the nuclei. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an ultrasonic wave-assisted nano-silver washing and sterilization method, which has a long-lasting antibacterial effect, cooperates with the vibration and sterilization of the ultrasonic cleaner, so that the cleaning and sterilization effect of the workpiece is better, and solves problems such as Recalcitrant bacteria such as streptococcus often risk their lives to escape from the explosion zone, so as to avoid being killed by ultrasonic waves, so the single ultrasonic sterilization effect is not very ideal.
