During the process of using vape, surely everyone has had a dry hit (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 into their body. In this article, I will talk in detail about the cases that lead to burnt cotton, and share some tips to help you recognize the situation of 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 you replace the 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 low points. At first, the coil feels very good to smoke, but the amount of vapor created 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 vapor, 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 rings even. The same goes for cases where you replace the cotton and squeeze the coil. The surface of the coil has convex and concave rings that prevent the inner surface of the coil from contacting the cotton to fully 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 start at the rings 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:
There is simply no juice left, causing the heat to transfer to the cotton, and the cotton burns. Usually because you are making the cotton too tight.
The case of soot causing juice residue, gradually it makes the tank heavier, creating a layer that prevents the juice from permeating, evaporating, and preventing the flavor particles from being shot. The culmination of this one-way situation is that your coil provides enough heat that the 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 with full e-liquid or leave the wattage a little lower, 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 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 layer).
