Static Problems In Plastic Bottle Production
What Causes Static?
Static charge is generated by friction from motion (for example, stockinged-feet sliding on a carpet) or contact and separation between two materials. Many of the materials used in clean measurement can create and hold very high levels of static charge for long periods of time.
Why Does This Happen?
Static is caused by friction. Many of the materials used in clean measurement areas are excellent insulators that can create and hold very high levels of static charge for long periods of time.
Effects of static on precision weighing
Static charges will both attract or repulse particulates. A strong charge on filter paper will attract particulates. Electrostatic force can cause movement in small objects, including the weigh pan of an analytical balance. Static charge attracts particles to weighing samples, transport carriers and scale components. Weighing inaccuracy, sample loss and contamination result. A static charge on samples and other objects in the weighing chamber interacts with the components of the scale, resulting in inaccuracies and “zero” drift.
How to Remove Static
The best method to remove static in weighing is with an ionizer. Ionizers create molecules called “ions” that combine with static charges and neutralize them. Transforming Technologies supplies specialized ionizers that do not require power cords, and airflow. They are easily mounted in chambers and do not disturb the fine powders.
