Experimental Study on the Mechanism of Micro-Particle Adhering to the Charged Surface of Membrane
In order to figure out the adhering mechanism between the airbome particle and the charged surface, the experiment was conducted by using the pE、 PET、 ITO films as the sampling surfaces.The films were placed under natural conditions, and the micro-image analysis system was used to analyze the experimental data quantificationally.It was found the adhesive process was not constant due to the change of conductive characteristic of the ITO film.When the sampling films were placed horizontally, the amount of particle adhering to the sampling films was in descending sequence as: PE > PET >Slides > 1TO.When the films were placed vertically, the amount of particle adhering to the PET film increased with the sampling time, while the amount decreased with the sampling time on the ITO film and Slides.However, there was not significant change on PE film during the sampling time frame.The particle size adhering to the surface changed from 0 to 30μm for all the testing materials, and 90% of the particle sized from 0 to 10μm.The amount of the particle size ranging between 1-4μm is the largest.The average size of particle at the beginning of the sampling was in a descending sequence as: ITO > PE > PET.The average particle size decreased with the sampling time went on, but it did not change significantly at the late stage of sampling.
