Charges, electrons, and ions cause static problems. When chemically different materials touch and separate, one will have positive charge, and the other

Good Static!

Published: March 15, 2010

While most static issues in the converting industry involve solving static problems, in other industrial applications, static charge plays an important and beneficial role.

For example, in 1907, Dr. Frederick G. Cottrell, a professor of chemistry at the University of California, Berkeley, applied for a patent on a device for charging particles and then collecting them through electrostatic attraction — the first electrostatic precipitator. Cottrell first applied the device to the collection of sulfuric acid mist and lead oxide fume emitted from various acid-making and smelting activities. Vineyards in northern California were being adversely affected by the lead emissions [http://en.wikipedia.org/wiki/Electrostatic_precipitator].
 
So, next time your cut sheets jam because the static level is too high, remember that the same static attraction is helping clean the air!

A winding roll on a slitter shows signs of high static. The crackling might be enough for your customer to notice. Will this roll be a problem? When is

Fieldmeter or Voltmeter?

Published: December 24, 2009

I received an interesting email question. What is the difference between an electrostatic fieldmeter and a non-contacting electrostatic voltmeter? And, if I had to pick either one or the other, which one is more useful for solving static problems?

How Much Static?

Published: December 18, 2009

Static is only one of many challenges in commercializing new products and in running production processes. How can we organize our information and prioritize our work so that each issue gets the attention it deserves, and no more? Analysis tools to drive data driven decisions and project prioritization concepts that have proven so valuable in managing operations should also be applied to static issues. To move ahead with on this, we need to establish a performance baseline that is acceptable, and identify maximum levels of static that are satisfactory.

How Static Bars Work

Welcome to the world of STATIC!

Published: July 29, 2009

Thank-you for visiting ‘Kelly on Static.’ Here, I will share some fundamental concepts of static electricity, apply these concepts to real-world roll-to-roll manufacturing operations, and answer questions on electrostatic theories and applications. I’ll be sharing my thoughts on how webs become charged, how static charge causes problems, and how to dissipate charge to prevent problems.
