Manufacturers/Suppliers: What's in my atomizer?

[ted26]

How many times when drunk did you light your cig the wrong way round and get a mouthful of that tasty flavour? yuck!

Well, after alot of researching it seems that the most common heat-resistant aromatic polyamide fibers are Nommex and Kevlar. Here is some toxicological info on what is produced when they burn. What do you guys think?



NOMEX & KEVLAR FIBER DUSTS ARE NOT AN
EXPLOSION HAZARD. BURNING NOMEX & KEVLAR PRODUCE HAZARDOUS GASES SIMILAR
TO THOSE FROM WOOL; MOSTLY CARBON MONOXIDE, CARBON DIOXIDE, NITROGEN OXIDES
& SMALL AMOU NTS OF HYDROGEN CYANIDE, AMMONIA, ALDEHYDES, ALIPHTIC
HYDROCARBONS & OTHER TOXIC GASES DEPENDING ON BURN CONDITIONS.

I'm not sure we can assume the Janty wick is Nomex or Kevlar, it might be something else.

If it is one of those and if it does degrade into the gases Jarvis listed above (in capitals for emphasis ) then I think Janty should be looking to use something more suitable. This is a weak point on atomisers anyway so maybe something can be developed that will address this degradation problem.

I haven't heard of or seen any dead Janty atomisers that have been taken apart for analysis. It's possible that the wicks don't degrade in them and Janty might have already addressed the problem?

Either way I don't care, I'm going to keep using mine and tell myself that it's not as bad as smoking ... probably.

Borrowed couple fibers from my ruyan disposable cigar and placed them between wires of my famous j-type thermocouple. Then heated using colt lighter to 1050C. No ash, smoke, or anything else for that matter. It started to glow yellow though. After cooling it appeared white just as I would expect from fiber of this type. Bended it with tweezers, it bends. Individual fibers can be seperated so it didn't melt. No sign of any burning.
Sucks to be right all the time.

The sweet spot of flame is couple millimeters above flame if someone wants to test this. White flame is hottest. Unfortunatelly I can't heat it to 1650C to see if it melts. Hot coal might reach that temperature. But measuring that high temperatures would need r or s type thermocouple which I do not have.

Weren't some of these gasses tested for/covered by the New Zealand Report (see pages 18 - 21) by Dr. Murray Laugesen ?

Yes this study didn't find any of these gasses under normal conditions, but It doesn't mention anything about when the fiber starts to burn out and that's the point were any hazardous gases might be emitted. I've not stopped smoking mine but I will definitely toss the atomizer as soon as it starts giving off that familiar burnt taste.

Does anyone know what temperature the coil reaches when it is operating? I can't seem to find this info anywhere, but I'm willing to bet it can get up past 200c, which is the maximum temp that most aramids are rated for frequent use.

[trog100]

a dull cherry red is 500 C.. i have seen my at a dull cherry red often..

i would guess the average running temp would be around 300 to 400 C.. which i repeat boringly so is why they dont last long.. many tested.. many dead.. dozens.. he he..

Ok, I've finally got a dead Janty atomiser that isn't covered by warranty and decided to take it apart to see what state the wick was in.


That's the wire that surrounded the pot, the pot with heating coil and the fibre wick.


The - 'heat-resistant aromatic polyamide fiber', matted with burned black crunchy stuff. I'm not sure if that black stuff is burned fibre or residue from eliquid. It's crunchy and crumbly, like the head of a burned match only a bit denser and harder.


This is the state of the heating coil. It has that black stuff stuck to it and the wire itself is very brittle, I think the metal degraded to a certain extent too.




So I'm not sure how much the wick degraded, there certainly didn't seem to be a lot of it left intact once the carbon stuff had been crumbled away.
