What microscope is used for dust particles, and what microscope is used for dust

The fineness of dust is what is used to indicate the number of dust and meshes
The fineness of the dusting dust has a direct influence on the selection of the dust bag. The determination of the number of dust is not easy to measure, generally can be observed with a microscope, and then there is calculation. The number of holes is the number of holes, which is the number of holes per square inch. The larger the mesh size is, the hole diameter is selected when the dust bag is used, and the normal temperature cloth bag generally exceeds 400 mesh. The film covering measures are adopted, and the high temperature cloth bag is generally above 300 mesh. The bag filter cloth must have suitable pores to allow the air to pass smoothly and the smaller the barrier. Fine dust enters the inside of the filter cloth. Once the fine particles of dust enter the filter cloth, they cannot be removed, resulting in greatly reduced air permeability of the filter cloth, increased dust removal resistance, and even the dust bag can no longer be used.
