Although each manufacturer adopt different ways when in the coating production of electrostatic eliminating measures, such as ion flow in addition to static electric appliance, the body. Power supply ground wire simple ground electrostatic eliminating measures, these measures have different eliminate electrostatic effect, but can't ensure safety in production.

Although each manufacturer adopt different ways when in the coating production of electrostatic eliminating measures, such as ion flow in addition to static electric appliance, the body. Power supply ground wire simple ground electrostatic eliminating measures, these measures have different eliminate electrostatic effect, but can't ensure safety in production.

    1、Ion flow in addition to static electrical appliances category measures, only suitable for the elimination of processed surfaces has accumulated static charges, not eliminate through subsequent guide roller to generate static electricity; Guide roller is numerous, especially near the coating head space space is limited, inconvenient to use this class in addition to static electric equipment in addition to static electricity.


    2、Using simple grounding resistance higher organisms. Power supply ground wire grounded to eliminate electrostatic measures, in theory is limited to use ohm's law: V = IR concept. Ohm's law is reflect electricity body for conductor, orderly evenly throughout the surface charge conditions, voltage, current, the relationship between the carrier resistance. And the carrier of static charges in coating production of insulation paper, plastic film, rubber, its static charges above the disorder spread on the insulator surface, so with the idea of ohm's law can't be solve the problem of electrostatic accumulation. Production site using electrostatic tester for measuring voltage value is a kv, but it is spreading in the paper, plastic film and the guide roll all the total energy of the surface electrostatic charge (voltage), and every moment can exist in material dispersed on the surface of guide roller contact of electrostatic voltage is limited. Scattered in every static charges on insulator could not by the National People's Congress to ground flow. Especially when the electrostatic charge is a positive charge, it is a load electricity body material in a number of material molecules after losing electrons of charged particles (cation), is still the load component of electric materials, obviously, based on the theory of ohm's law, a positive charge is impossible along the earth wire of the National People's Congress.
