Explain the principle and measurement index of static eliminator
The so-called static eliminator means that a certain value of high voltage is generated by the high-voltage power generator and applied to the discharge needle. Due to the discharge effect, the air around the discharge needle is ionized and the same amount of positive and negative ions are generated. The same amount of positive and negative ions are delivered to the needs through the airflow. A space or object that eliminates static electricity, in which positive ions are neutralized with negative static electricity, and negative ions are neutralized with positive static electricity, so as to achieve the purpose of eliminating static electricity and preventing static electricity.
Test index of static eliminator
The main indicators to measure the performance of static eliminators are: static elimination speed, ion balance (* final residual voltage) and overall stability. According to the test standard ANSI/ESD STM3.1-2000 of the ESD Association, the static elimination speed refers to the time required for static electricity to be neutralized from ±1000V to ±100V. The faster the speed, the better the performance; within the specified time (usually 20S) The residual voltage value after static electricity is neutralized is the ion balance, and the ion balance is close to zero for superior performance. For the desktop ion fan, the test point is: 30cm directly in front; for the ion blowing gun, the test point is: 15cm directly in front; for the suspended ion fan, the test point is: 45cm directly below, using the instrument: ME-268A-1T or CPM374 CHARGED PLATE MONITOR (static eliminator detection analyzer); the long-term stability of the performance indicators of the whole machine is more and more valued by customers and users. How to ensure that the static eliminator can ensure good performance after a long period of work The speed of electricity dissipation and the degree of ion balance are the issues and research topics that every manufacturer must consider. Haiweida Airlines has carefully studied the selection of materials and the manufacturing process with good intentions.
