The specific content of Dongguan dust cloth, according to the requirements of the clean room has the corresponding cleanliness, staff work clothes itself can not be dust, itself can not produce static electricity, that is, anti-static function of the dust jacket, can not produce dust, but also can not absorb dust.
Static electricity has a physical feature that can attract small objects, which is the mechanical effect of the electrostatic force, due to the role of electrostatic forces, will be small dust adsorption, these dust will accumulate in the surface of the semiconductor, which is easy to form a bad product, in this regard, a purpose is to achieve clean. Usually clean cloth to wipe clean material has several aspects to define: Dongguan clean cloth
1 no volatile matter in the solvent, usually using a solvent, it is used to evaluate the solvent. The amount of residue is usually measured with a precision weighing device, but the user can also be used to wipe the fog in a way to determine whether the residual is required.
2 dust dust emissions, including the release of dust in the air and the release of dust in the liquid. A lot of people think that the problem of the dust is not clean, in fact, it is just the opposite, shake off the dust is a clean cloth to wipe the material itself is a matter of nature, but the number of bits off.
3 the amount of the dust free ion, mainly to check the high activity of metal ions and non-metallic ions. If you have a precision metal material on the surface of the polished surface, it is recommended that the precipitation of ions as an important examination project, because the active ion is very easy to destroy the surface of precision metal through the battery reaction.
