Polystyrene: UV Lamp Test
« on: June 05, 2019, 11:46:18 AM »
Iíve been busy this week trying out Peroxide bleaching of a (pure Polystyrene) AEI Neophone.

Iíve written down the procedure and results with photos but might be a tad long to read....?

Here is the last bit. I tried a Cream Peroxide treatment under UV lights.

The endcaps were under the UV bulbs for one hour.

What do you guys think, same or can you see any lightening?

Iíve been doing this Peroxide bleach experiment for 3 days, I would have continued for more than an hour today but other things called me away....

...everything looks like it has a tint of orange to me now.

I'm thinking, it will take much longer than a hour to tell any difference?

I like your set up...

I run my black-light overnight with the phone pieces in peroxide and water. That does the job.

Thanks.  :)

You are correct, more than an hour needed on this bit of the project .....I think after 3 days I got a bit impatient with this part. On reflection hourly intervals though most likely a good thing, this little unit of mine probably not safe to leave on unattended for long periods. Other chores called me away so not wanting to leave it unattended I had to call it a day.

That looks interesting. Black light....
Could you give more info on your setup?

Oh - Lightbulb (literally) moment, your photo has given me an idea....  :D

Have you tried short-wave UV light?

No I haven't, have you tried it?

That might give uneven results because of QSB.

QSB?

Sorry, I should have refrained from posting that.

QSB refers to a variation of signal strength due to atmospheric or geographic conditions. It is common in long distance short wave radio transmissions.

It doesn't apply to nearby short wave UV transmissions. Short wave UV is higher energy UV.

Jack; wouldn't it be "apples n' oranges" considering one concerns radio waves and the other light waves?
