Static electricity issues in lined centrifuges
Thread Content
Separated materials: 95% ethanol, hydrochloric acid, propanol, and a mixture of these materials. pH of the materials: between 4 and 5. Separation equipment: centrifuge with plastic lining throughout. Current measures: the separation process is carried out under nitrogen protection, with online monitoring to control oxygen levels. Concerns: Since it is a centrifuge with plastic lining, it is difficult to ensure proper static grounding; what is the risk of static electricity during manual unloading? Furthermore, how can static grounding be effectively achieved under such operating conditions?
1. Even centrifuges with plastic lining do not achieve satisfactory electrostatic effects, unless an appropriate amount of activated carbon is included in the lining to improve its conductivity; however, it is still necessary for such centrifuges to have electrostatic properties. 2. The risk is low during proper centrifugation, mainly due to nitrogen protection. 3. Significant wind noise occurs during manual unloading; the following methods are provided for reference: 1. Use conductive bags for receiving the material and ensure they are grounded; 2. Have the operators wear anti-static and static-preventing clothing; 3. Wait for a period of time after centrifugation has stopped before unloading the material. Facilitates static electricity discharge. Any substance can conduct static electricity, only at different speeds.
Thank you! :handshake
Increasing humidity can help reduce the generation of static electricity. There are also anti-static plastics available, so it is sufficient to request that anti-static plastic be used during ordering.
I want to tell everyone that the hazards of static electricity are significant; I have seen videos of gas station explosions caused by static electricity, so it is essential to take this seriously.
It’s okay to connect it to ground,,,
