During the process of using vape, surely everyone has had dry hits (scorched or burnt cotton) at least ten times. When opening the coil and replacing the cotton, they are shocked by the pile of sticky, black cotton, I bet everyone wonders how much charcoal smoke they have inhaled. In this article, I will talk in detail about the cases that lead to burnt cotton, and share some tips to help you recognize burnt cotton as soon as possible.
Causes of cotton scorching:
Because the soot in the essential oil tank prevents the essential oil from rising, causing the cotton to burn.
Case 1:
The cotton you replace is too thin, when replacing cotton with a cotton core that is too thin, you think they will produce good juice, this is not true. Because the cotton core is too thin, when the essential oil enters, due to the surface tension of the essential oil, the circumference of the cotton line in the coil core shrinks, creating gaps. At first, the coil feels very good, but the amount of vaping increases very quickly because the points are too full of essential oil, the evaporation is not decisive. Imagine it like cooking soup, when there is no vaping, the juice is clean, the vapor rises to the other parts still fragrant, but from the burnt part to the burning part, it is extremely fast. Not to mention whether the juice you use is of the best quality
Case 2:
The coil is misaligned. When you roll the coil on the coil jig, it is very important to roll it tightly to keep the loops even. The same goes for cases where you replace the cotton and squeeze the coil. The surface of the coil has concave and convex loops that prevent the inner surface of the coil from completely contacting the cotton to lead the essential oil up. These points also create lumps like case 1 and create a jam. Or it is almost burned right from the beginning at the loops that are squeezed.
Case 3:
There is a hot spot on the coil, which is very difficult to detect, but it causes the cotton and essential oil to form a sticky layer, which is very difficult to detect on the first day of changing the cotton. Or the cotton will burn right from the start.
Due to cotton burning from the beginning:
Simply no more juice causes the heat to transfer to the cotton, and the cotton burns. Usually because you made the cotton too tight.
The case of soot causing juice residue, gradually it makes the tank heavier, creating a layer that prevents juice from permeating, evaporating, and preventing flavor particles from being fired. The culmination of this one-way situation is that your coil provides enough heat that the other tank covers your coil without any juice, and it burns.
Tips to know before your vape device burns cotton:
When you first change the cotton, it smells great, but after only 3-4 hours of use, it suddenly becomes bland without burning.
When you vape full of e-liquid or leave the power a little below the limit, it's fine, but just adjust it to 5W or take a little longer puff and you'll smell a bit of burning. You should make sure to adjust the coil evenly and replace the cotton.
When you are smoking and see bubbles rising abnormally (bubbles rising on both sides after a while of smoking only on one side, rising on one side from the beginning is fine), or the bubbles suddenly get bigger (at this time, not only the cotton pad but also the entire tank).
