Abstract

It is drawn up a list of physical laws describing the behavior of an aerosol system. First the influence of sedimentation, diffusion, coagulation and impaction is described. In the second part the evaporation and the condensation from droplets in relation to the vapor tension of disinfectants is regarded. Finally the circumstances under which the vaporized disinfectants will reach the microorganisms by diffusion are described. It is demonstrated, that the terminus technicus "aerosol disinfection" should be restricted to systems, that operate with drop diameters less than or equal to 10 microns.

摘要

列出了描述气溶胶系统行为的物理定律清单。首先描述了沉降、扩散、凝聚和撞击的影响。第二部分考虑了液滴的蒸发和与消毒剂蒸汽压相关的凝结。最后描述了汽化消毒剂通过扩散到达微生物的情况。结果表明，术语“气溶胶消毒”应仅限于使用直径小于或等于10微米液滴的系统。
