How to evaluate the quality of clean cloth
1. The amount of dust generated by the clean cloth, including the amount of dust particles released in the air (APC) and the amount of dust particles released in the liquid (LPC). Many people think that shaking and dwarfing is an intolerable problem for clean cloths. In fact, it is not. On the contrary, shaking swarf is a physical property of the clean cloth wiping material itself. It is only the level of chipping.
2. The amount of ions released by the dust-free cloth is mainly to check the metal ions and non-metal ions with high activity. If your wiped surface has precision metal materials, it is recommended that the precipitation of ions be an important inspection item, because active ions can easily damage the surface of precision metal through battery reactions.
3. The non-volatile matter (NVR) of the lint-free cloth in the solvent, usually the solvent is used, just use which solvent to evaluate. The amount of residue is usually tested with precision weighing equipment. However, the user can also determine whether the residue of the dust-free cloth is within the required range by trying to wipe whether it has fogged (special attention: check the strength of the lamp) It will have a great impact on the test results. If the light is very strong, all dust-free cloths will find foggy residue)
