As you have probably noticed this morning, a real panic begins to surge in the world of vape following an article dealing with the interview given by the Dr. Konstantinos Farsalinos on a " RY4 radio »On May 22, 2015 (it starts to date…). In this one, the researcher in cardiac surgery from Onassis warns us of a risk about the practice of " Dry Burn "(Make her resistance blush to clean her).
FARSALINOS: "MAKING A DRY BURN DESTROYS THE MOLECULAR STRUCTURE OF METAL"
In this famous interview, we find from the 44th minute Dr. Farsalinos and here are his words: " I want to advise, not only to vapers but also to reviewers: don't make the coil blush. This is one of the worst practices: to make the coil red in order to tighten the turns or to check if the heating is uniform. This is disastrous. Because when we heat the metal to red, we destroy the bonds between the molecules of the metal, thus greatly facilitating the emission of metal in the vapor. It's the worst thing you can do. »Then he adds a little later in the interview« It only takes one dry burn to destroy the molecular structure of the metal. " and to finish " If you want to clean the coil, use water or alcohol ((on the metal wire)). Even acetone, as long as you wash it off with water ”. Obviously it did not take more to see the vaping community in turmoil, everyone wondering whether or not we were in danger with our montages.
A PANIC AMONG THE FRENCH STEAMERS ...
While this interview was released 3 days ago, and nobody really had a reaction in the world in France, we immediately take the fly without even asking the right questions. Some are already talking about stopping vaping, banning kanthal, buying temperature-controlled mods (Pipeline / Hana Modz / Vapor Shark) or using titanium coils to solve the problem. But if so far there has been little reaction, it may be quite simply because the Dr. Konstantinos Farsalinos forgot an important notion: There are no molecules in metals, there are only metallic cations and electrons which move freely. In addition, many people are starting to step up to the plate by explaining these phenomena by the figures: The proof is that it is impossible to have any destructuring with the temperature of a red coil.
THE METALS OF OUR RESISTANCES DESIGNED TO STAY STABLE UP TO 1900 °!
Indeed, as explained to us German magazine "Dampfer" in its first issue of the year (available for free in Pdf) the maximum temperature used by the e-cigarette (and therefore for dry burn) will never be enough for a serious decomposition of matter. At this temperature of a dry burn (approximately 800 °) the metal will not be able to create free particles and even in the worst case, they would be extremely insignificant. The metals used to make resistors are designed to remain stable up to 1400 ° C which is double the temperature of a dry-burn. For the more courageous we will add these more technical comments:
« When we speak for example of Kanthal A1, we are talking about a stainless steel for which it is necessary to reach a temperature close to 900 ° C to begin to have a non-permanent transformation at the level of the atomic structure of its atoms (its structure in Centered cubic network will transform into face-centered cubic up to more than 1300 ° C) without changing its characteristics and it will become identical to cooling again. It is just a change in crystal structure and in no case a "molecular" change (improper term because steel does not have a "molecular" structure but a crystal structure) of its components! Until these famous 900 ° C, the iron in the alloy will even be unable to dissolve the carbon present at only 0,08%, so I wouldn't even speak of Manganese (present at a rate of 0,4%) , Silicon (0,7%) or Chromium (between 20,5 and 23,5%) which will be unable to change state! "(Frederic Charles)
EDIT: THE RESPONSE OF DR FARSALINOS
« I say nothing more than common sense tells me. These threads are not made to evaporate a liquid that you will inhale later. Studies find traces of metals in the vapor of e-cigarettes. It is common sense that when you heat metals until they redden, you affect their molecular structure. Along with the corrosive effects of liquids, it is possible that some metals react with the coil. I haven't done any measurements, but with common sense I recommend what I said earlier. If anyone wants to continue to “dry burn” I have no problem with that. I am not going to punish anyone and I am not going to stop anyone from doing it. The study conducted by Williams proved the presence of nickel and chromium from the nichrome wire, and they had not done "Dry burn". I guess your yarn will get even worse if you use “Dry Burn”. After that, that remains my recommendation. »
