Dust-free cloth quality assessment method
For the evaluation of the dust-free cloth material, we should establish a combination of the cleanliness evaluation and the actual application effect. Generally, whether the dust-free cloth is suitable or not, we should first summarize what kind of wiping cloth is selected, and then propose the dust-free cloth. Cleanliness requirements.
The cleanliness of the dust-free cloth wiping material is one of the key aspects of its quality abnormality. The cleanliness level directly affects the dust-free cloth decontamination ability. Generally, the cleanliness of a clean cloth wipe is defined in the following aspects:
1. The amount of dust generated by the dust-free cloth, including the amount of dust released in the air (APC) and the amount of dust released in the liquid (LPC). Many people think that jittery chipping is an intolerable problem of dust-free cloth. In fact, on the contrary, the jitter-removing chip is a medium-physical property of the dust-free cloth itself, but it is only how high or low the chipping is.
2, the amount of dust-free cloth ions, mainly check for high-activity metal ions and non-metal ions. If the surface of your wipe is made of precision metal. It is recommended that the precipitation of ions be an important inspection item because the active ions easily destroy the surface of the precision metal by the battery reaction.
3. The amount of non-volatile matter (NVR) of the dust-free cloth in the solvent. Usually, the solvent is used, and the solvent is used for evaluation. The amount of residue is usually tested with a sophisticated weighing device, but the user can also determine if the residue of the lint-free cloth is within the required range by wiping it or not (special attention: check the strength of the lamp) It will have a great impact on the results of the test. If it is under very strong light, all the dust-free cloth will be found to be foggy.)
