In order to remove old wallpaper.
Forgive me, it's pretty late, and it's the first time I've ever visited this website.
I was in bed when this website and this idea popped into my head
Just print over it

Audio Frequency Heat

Probably bogus, but to help out a newbie... [Boomershine, Oct 15 2010]

Welcome to the Halfbakery! Is there any evidence that glues will fail or decompose when exposed to a specific frequency? I can sort of see the logic if the glues were crystalline in structure but I'm pretty sure this isn't the case. |
|
| |
"the frequescy to desolve" glue? What's this - Klingon? |
|

Greetings! And welcome! If websites pop into your head before you have ever visited them, you may find Google would be interested to hire you. |

Welcome, [TheDoc], to the Halfbakery! |

Problem is......as [hippo] points out, there's nothing in your
post to suggest that wallpaper glue would be dissolved by
any particular audio frequency..... |
|
| |
I dunno Max.....I turned on the radio the other morning and there was a recording of the sound of Sarah Palin farting under water. When I had finished listening, I noticed that the cereal box, which was sitting adjacent to the radio's speaker, had fallen apart and all the glue previously holding the cardboard sides in place, had collected in little puddles at the corner points. |
|
| |
Sarah Palin gets me all melty, too. |
|
| |
I used to work with a carpenter that had some sort of radio-frequency glue heater. I dunno if it was for drying the glue or for removing it. |
|
| |
A sonic frequency isn't going to do much. |

I would like this website to pop into my head whilst in bed, then I wouldn't have to get up and go to my computer!! Hi! |

Isn't that article about using heat to produce sound? |
|
| |
Also, I don't think most wallpaper glues soften with heat -
they're water-based pastes. Steam softens them, but I
believe that's mainly the effect of the water diffusing into
the glue (accelerated, admittedly, by heat). |

Well, excuuuuse me for trying to help a new guy...a
little latitude would be nice. (I certainly didn't *read*
the thing, but if you're going to be picky about
this...) |

From the link:
"Conductor is heated and allowed to cool using an
audio frequency AC current." (I think they meant to
leave out the "and allowed to cool.") |

Hello. I reckon you could make an adhesive foam from a substance which is quite brittle when it solidifies, wait for it to set, then aim a resonant frequency of sound at it. Cavitation might be another option. |

As, indeed, does plaster...This would be a wall/paper
remover. |
|

Well roll on the sonic disruptor gun then. |

Um, the 60 hertz that Americans use for AC current is an audio frequency. I once hooked up an audio amplifier to a bad power supply and got a pure 60 hertz sound, damned loud. |
|
| |
But an AC current is not audio, until it is run through a sonic machine. Whatever that is. |
