detrimental info for atomizer cleaning!!!

[Sun Vaporer]

Thank you for all your help Sun. I will now officially un-hijack this thread. My apologies!

You are welcome--as the original OP correctly points out--the contact points snapping is the real issue in atomizer failure. Presevation is what we are working on -----Sun

Before this becomes folklore, I should point out that the deposit is most definitely NOT chromium oxide. It is juice residue, plus a bit of tin (presumably from the solder joints, which is a bit strange as the tin is likely only a small fraction of the solder; but the thinking is that this is due to some kind of electro-chemical action or perhaps a 'tin whiskers' effect).

Nichrome

From Wikipedia, the free encyclopedia

Jump to: navigation, search
Nichrome is a brand name for a nickel-chromium resistance wire, a non-magnetic alloy of nickel and chromium. A common alloy is 80% nickel and 20% chromium, by weight, but there are many others to accommodate various applications. It is silvery-grey in colour, is corrosion resistant, and has a high melting point of about 1400 °C. Due to its relatively high resistivity and resistance to oxidation at high temperatures, it is widely used in heating elements, such as in hair dryers, electric ovens and toasters. Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.
Nichrome is used in the explosives and fireworks industry as a bridgewire in reliable electric ignition system, such as electric matches and model rocket igniters.
Nichrome wire is commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used because of its ability to withstand the high temperatures that occur when a clay work is fired in a kiln.
The alloy tends to be expensive due to its high nickel content. Distributor pricing is typically indexed to commodity market prices for nickel.
Other areas of usage include motorcycle silencers, and in certain microbiological lab apparatus.
For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide. [1]

How do you take apart a 510 atty? is it possible?

How do you take apart a 510 atty? is it possible?

510 attys are very hard to take apart........The glue is amazing. Only one i've had apart was due to dropping it off a ladder twice and just dropping in several other times. If you do ever get one apart make sure to pull all the fibers between the bridge and the coil out(eventually they will start to burn) They do not affect the performance.

Actually I've had 2 apart(but I bent the **** out of it and buggered it up a lot even with heating the glue.) I'm amazed I got it back it was so bent up, but it tasted so bad I had to

Yes, of course there is a minute layer of oxide. But that's not the problem!

The deposit that kills atomisers can get bigger than the coil itself. It is NOT chromium oxide (this would never be more than a few atoms thick) !

It is charred juice residue.

ps: a correction re tin in the deposit; it can be the major constituent of some solders.

Kinna--I do not know why that is so hard to understand. I guess that is why we lost Exo---------Sun

Maybe Exo will be back one day ...

I don't blame the poster - it's an easy mistake to make. The oxide is a fact; but it is so tiny in amount and didn't even show up in the deposit analysis that Exo did.

The juice deposit is clearly demonstrable by the teaspoon method (heat some juice on a teaspoon and see what's left after most evaporates).

Need to dig up one of those 'horror' pictures of a typical atty after a month's use !
