Regarding the special calcium carbonate for high-end cigarette paper, the United States and France are at the leading level in this regard. China has started the exploration of special calcium carbonate for the paper industry since the 1980s, and produced several different types of special calcium carbonate products for the paper industry. However, there are few types, low production volume, and outdated production process equipment, and high-end commodities depend on imports.
Encapsulated cigarette paper, called coil paper, or large screw thread paper, is very different from general printing paper. For example, materials are generally produced with hemp as the main raw material, and are characterized by good water absorption capacity, high ductility, good overheating, and low odor. You can dismantle a cigarette, flatten the paper, ignite a corner with a cigarette butt, and you will find that a whole piece of paper will gradually burn, copper paper is definitely not acceptable, and the copper paper is thick smoke and pungent. The taste of the paper is slightly smoky, and the taste is relatively low.
If you want to make cigarettes by hand, you can’t use thin paper, but you can’t use newspapers and magazines. Printing paper and printing ink are harmful. Different cigarettes are commonly used in different coils. In addition to materials, many businesses pay attention to the coils.
After adding light calcium carbonate to the cigarette paper, it can improve the opacity, fineness, touch and flexibility of the printing paper, improve the air permeability, and adjust the burning rate of the cigarette.
Because of unscientific particle shape and particle size, ordinary domestic light calcium spreads in blocks on cigarette paper. The calcium carbonate sheet blocks the space between the chemical fibers in the printing paper, and the chemical fibers that are not blocked have high air permeability, which is easy to cause uneven air permeability. and unstable, and the paper version is relatively thin to the touch and has a poor refractive index.
The imported calcium carbonate is divided into layers on the paper, and there are safe channels between the calcium carbonate crystal particles, which cannot block the gas basis, so as to ensure the uniformity and reliability of the air permeability of the cigarette paper. The air permeability and heat resistance are relatively high, and the performance indicators are good, but the cost is high.
Adding calcium carbonate to cigarette paper has the following benefits:
(1) Raise the refractive index so that the tobacco pipe does not leak the background color, which is also an important factor for cigarettes.
(2) Adjust the burning rate so that the burning rate of the cigarette paper and the tobacco pipe is consistent, and the cigarette is kept burning without extinguishing.
(3) The ash content of the cigarette paper after burning can be firmly bonded to the tobacco pipe, and the ash is good.
(4) Improve the fineness of cigarette paper and make it more beautiful and elegant.
(5) Make the cigarette paper have high air permeability, reduce the amount of tar, and improve the air permeability of the cigarette paper.
