Verification of Aluminum Tape Effect | Cyclone Vacuum Cleaner Edition

Fine dust was stuck in the dust cup of the cyclone vacuum cleaner due to static electricity. I thought that if I put aluminum tape here, I could confirm the effect of static electricity removal. Instead of aluminum tape, I stuck a 10mm wide copper foil tape.

It is a state of the garbage cup before applying the copper foil tape. After cleaning, throw away the garbage inside and turn it for about 30 seconds. You can see how the dust is stuck inside due to static electricity. The first photo shows a copper foil tape attached to this.

This is a photo after applying copper foil tape and turning the vacuum cleaner for about 30 seconds. Air flows counterclockwise through the garbage cup. It flows from left to right in the photo. There is a dust-free band on the leeward side (right side) of the copper foil tape.

This is a picture of the inside of the garbage cup. There is a dust-free band on the leeward side (left side) from the middle of the copper foil tape. It is probable that the copper foil tape affected static electricity and changed the adhesion of dust.

For further verification, the position of the copper foil tape was shifted and reattached. If you shift the position, you can easily see that a dust-free band is formed in the place where the original copper foil tape was pasted.

This is a photo after changing the position of the copper foil tape and turning the vacuum cleaner for about 30 seconds. There is a dust-free band where the copper foil tape is applied. In addition, the place where it was originally pasted has dust attached like other places. It was confirmed that there was a change by pasting the copper foil tape.

Verification with aluminum tape. I cut a 40mm wide aluminum tape about 10mm and attached it.

This is a photo after turning the vacuum cleaner for about 30 seconds. You can see that there is a dust-free band and that the dust is thin overall.

In this experiment, it is not possible to explain the phenomenon, but it was found that attaching aluminum tape (copper foil tape) makes it difficult for dust to adhere. One of the effects should be less resistance to air flow due to dust. I think that this experiment proved that there is some effect by sticking aluminum tape (copper foil tape) in a place where static electricity is likely to occur due to friction with air.
