From the birth of electronic cigarettes to the present, the atomizing coil has undergone about three iterations (or three major materials), the earliest is the glass fiber rope, and later the cotton coil appeared, and then the ceramic coil. All three materials can absorb e-liquid, and then heat through the heating wire to achieve the atomization effect.
Each of the three materials has advantages and disadvantages. The advantage of the glass fiber rope is that it is cheap, and the disadvantage is that it is easy to break. The main advantage of the cotton coil is that the taste is restored the best, and the disadvantage is that it is easy to burn. The industry is called paste coil, which will absorb the burnt smell. The advantage of the ceramic coil is that it has good stability, is not easy to break, and will not burn, but under the current technology, all materials have the risk of oil leakage.
Glass fiber rope: The earliest atomized oil guide material in the early stage of electronic cigarette development was glass fiber rope.
It has the characteristics of high-temperature resistance, strong oil absorption, and fast oil guiding speed. Between 2014 and 2015, because many e-cigarette users were worried about the phenomenon of "dropping powder" from glass fiber ropes into the lungs, this material was gradually eliminated by mainstream equipment at home and abroad.
Cotton coil: At present (big smoke electronic cigarette) mainstream atomizing coil material.
Compared with the previous fiberglass oil guide rope, it is safer and the smoke is fuller and more realistic. The cotton coil structure is in the form of a heating wire wrapped around cotton, and the atomization principle is that the heating wire is atomized decoration, and the cotton is the oil-conducting material.
The biggest advantage of the cotton wick is the taste! The reduction degree of the smoke oil taste is better than that of the ceramic coil, and the amount of smoke should be denser, but the power of the smoke rod is not completely constant, which will cause the overall performance to fluctuate. It's exceptionally good, and the experience of using it deteriorates more and more later, and there may be a phenomenon of smoke fluctuating in the middle. If the power of the cotton coil is too high or after being used for a period of time, it is easy to cause the phenomenon of smearing, and the situation that the power is suddenly too large to cause the dry burning of the cotton coil cannot be ignored, but the ceramic coil does not have this concern.
The phenomenon of unstable output power can be optimized by chips. For example, the electronic cigarette of INS uses low voltage to achieve stable power output to ensure that the taste of each puff is the same under different power levels.
Ceramic coil: Mainstream atomizing coil material of pod vape (all Relx series, MOTI, Vvild, Snow Plus, YOOZ, INS, and other mid-to-high-end products of e-cigarette brands all use ceramic coils).
The ceramic atomizing coil is more delicate and smoother than the cotton coil, but the reduction degree of the smoke oil taste is a little worse than that of the cotton coil. The main advantage is stability and durability, which is the reason why many merchants prefer ceramics. Ceramics rarely have a paste-coil phenomenon like cotton coils, and they are almost always stable. Under the condition of constant voltage, There is little difference in the fullness and taste of the smoke.
The first generation of micro-porous ceramic atomizing coils are molded by injection molding, and the ceramic material is fired around the heating wire.
The second-generation microporous ceramic atomizing coil uses printing to embed the heating wire on the surface of the microporous ceramic substrate.
The third-generation microporous ceramic atomizing coil is to embed the heating wire into the surface of the microporous ceramic substrate.
And for some pods that can be refilled with oil, choosing ceramics is not only durable but also cleanable. And the cotton coil you have no choice but to change the cotton.
Above, if you like the fuller and more realistic feeling of the smoke, choose cotton coil, and if you like the nuanced taste, choose ceramic.
Cotton coil and ceramic coil are not incompatible with each other. They each have their audience. Only by constantly improving themselves can they better serve users.
