The dust can adsorb charged ions, about 90% -95% of the suspended dust is positively or negatively charged, the stability of the dust in the air is enhanced by the repulsion of the like charges, the dust is promoted to be gathered and deposited on the mesh cover by the attraction of the opposite charges, and the charged body has the property of attracting light and small objects, so the dust can be gradually accumulated and adhered on the mesh cover. According to the literature, solid suspended matters with the particle size of less than 75 microns in the air, particularly dust with the particle size of more than 0.1-10 microns, are reported to have higher dispersity, the finer particles of the dust are, the longer the floating time in the air is, and the dust in the air can also have bacterial corpses, oil stains, water and some flocculent fibers, so that the appearance of the dust suspended in the air is very complicated, the multi-component dust is more easily enriched and adhered to a plastic mesh cover, and the mesh cover gradually becomes very dirty and unattractive after a long time, therefore, the development of an easily cleaned dust-proof mesh cover has important practical application value.
