Web27 feb. 2024 · How the electrostatic therapy Therapy works-EFT is a simple, non-invasive technique using static electricity which produces fast demonstrable clinical results. The theory is that when an electric filed with high voltage AC is applied on a human body, cells metabolism is stimulated by supplementing ions and the Acid-Base Balance of Electolyte … WebElectronic devices are fundamental to our global economy, improve our lives immeasurably, and underlie virtually every aspect of modern life. Yet very few of us have any idea of how electronic devices actually work. In fact, these increasingly complex devices operate on a few basic principles that are both fascinating and easy to understand.

Web11 aug. 2024 · Electrostatic spraying cleaning kills germs, bacteria, and viruses from the surfaces and can last for a while. It has demonstrated effectiveness against viruses like SARS-CoV-2. Therefore, per the EPA’s Emerging Pathogen Policy, these products can be used against SARS-CoV-2 when used correctly on hard, non-porous surfaces. Web27 nov. 2024 · Static generation is proportional to the speed of the material. Faster speeds create higher charges. The speed of the material also determines whether more than one static eliminator bar is required. Some years ago, the rule was that if the material speed was over 300 m/min then 2 or more AC static eliminators were required. flintstones way-outs
