Nanometer zinc oxide is originally amphoteric oxide, divided into powder and liquid two, in the actual production, often encounter the test of nanometer zinc oxide failed, then what is the cause of nano zinc oxide loss of effectiveness? Kenada new materials for your answer.
The reasons for the unsatisfactory antibacterial effect of nano-zinc oxide powder (KND-HQ20W) used in plastics, especially in antibacterial films.
1 Nano zinc oxide (KND-HQ20W) dispersion is not uniform, can be analyzed through transmission, observe the dispersion of nano zinc oxide KND-HQ20W in plastic sheets.
2. The amount of nano-zinc oxide is insufficient, and the recommended amount of common bacteria is 0.5-0.6%, and fungi is 0.8-1.5%.
The application of nano zinc oxide dispersion (KND-HF30 series) in textile finishing is not ideal for antibacterial reasons
1. In the process of using with softeners, anions and ions do not match.
2. Caking and hard precipitation occurred when the nano-zinc oxide dispersion was placed for too long.
The above is to introduce the cause analysis of the failure of nano zinc oxide, and I hope it can be helpful to you.
