STATIC CHARGE GENERATION
STATIC CHARGE GENERATIONWhenever two dissimilar surfaces placed in close contact are separated, one surface loses electrons and becomes positively charged, while the other surface gains electrons and becomes negatively charged. This is known as triboelectric charging. Any material, solid or liquid, may be charged triboelectrically by friction, contact and separation of materials, or fluid flow. The magnitude of the charge will be affected by the surface condition, area of contact, speed of separation or rubbing, and the humidity. Whether the material remains charged depends on its conductivity and the availability of a path for the charge to flow to ground. If charge is allowed to accumulate on a material it may attract and bond particles to its surface.The prin…
