What is the life expectancy of a static control device?
A static control device will work for millions of cycles if the charged paper does not touch the fibers. Electro Static Technology recommends a distance of 2mm to 7mm between the fiber tips and the charged paper.
How can I measure the amount of static charge on a surface?
Static charges are difficult to measure directly. An indirect method is to measure the surface voltage with an electrostatic field meter. The surface voltage can be measured before and after the installation of a static control device. The amount of voltage reduction is an indicator of the static control device effectiveness.
Does a static control device remove all the charge from a charged surface?
No, the electric field between the fiber tips and the charged surface will be reduced as the charge is reduced. At some point, the electric field will be reduced to a level that will not sustain ionization. All passive static control devices leave a residual charge. The objective of a static control device is to reduce the charge to a level that will not cause a paper process flow problem.
