Description

       Cigarete and cigarete paper including flints of rare earth elements}

     Safe and harmless ignition when smoking is mixed with appropriate amount of tobacco species or cigarette powder to produce a fine ignition when smoking to induce a visual and auditory stimulation to smokers when smoking.

       Rare earth elements refer to scandium, yttrium, Group 3 of the periodic table, and the 15 elements of the lanthanide series, which are atomic numbers 57 to 71, usually silver-white or gray metals (La, Ce, Pr, Pm, Nd, Pm, Sm, Eu, Gd). , Tb, Dy, Ho, Er, Tm, Yb, Lu) Rare earth metals have unique physical and chemical properties in all industries such as electronics, metals, chemicals, nuclear power, optical glass and abrasives, fluorescent materials, pigments, magnetic materials , Magnetic bubble memory material, metal additive, high temperature high strength ceramics, reactor structure and moderator, hydrogen absorbent, etc., and its chemical properties are used as oxygen scavenger because of its high affinity for oxygen. There is a gas absorbent use such as a ignition alloy, a light bulb and a vacuum tube. It is also used in high temperature materials due to the formation of stable oxides and high melting point sulfides. Because rare earth elements are physiologically inert, they are harmless to the human body and therefore have no pollution problem. Cerium oxalate and niodymium isoniconate appeared in the 1930s as medicines for seasickness and thrombosis. In 1903, the Austrian chemist Welsbach was a ignition alloy composed of 50% cerium (Ce), 25% lanthanum (La), 15% neodymium (Nd) and 10% praseodymium (Pr) iron (Fe). Auer alloys were invented and are now called mische metals and are used for oxygen removal of pyroalloys or vacuum tubes.

   To exert the ignition effect by mixing the igniter with tobacco or tobacco paper, the first solution should be stable and harmless to the human body. First of all, it should not be affected by moisture, so it can be added in the manufacturing process of tobacco or tobacco paper. Second, it should not be ignited at room temperature or in contact with moisture. Third, it should be harmless to human body.

       First, it should be able to maintain flammability at the time of cigarette paper production or contact with moisture after the completion of tobacco. Classic flammable substances such as sulfur used in gunpowder or matches are vulnerable to moisture and lose their flammability when they come into contact with moisture. Rejection is caused by the peculiar smell. When ignition alloy powder is used, tobacco paper can be used in the manufacturing process because it is not nourished by moisture, and its flammability can be maintained even after contact with moisture after completion.

      Second, stability should be maintained since it should not ignite at room temperature or in contact with moisture. Organometallic compounds such as organometallic compounds, alkylaluminum, and alkyllithium, especially lower alkylmetal compounds, are generally highly reactive and are resistant to heat. Unstable and spontaneously ignite in the air. In particular, lower alkyl metals, alkali and alkaline earth metal compounds of Groups 3A (B, Al, Ga, In, Tl), Groups 2A (Be, Mg), and Groups 2B (Zn, Cd) are particularly strong. On the other hand, in higher alkyl metal compounds, spontaneous flammability is reduced. Mg, Al, Zn Sb, Bi are compounds that combine with CH3-, C2H5-, C3H7- in the alkyl group ignite soon after exposure to air. In particular, alkylaluminum is widely used in the organic synthesis industry such as polyethylene, polypropylene polymerization of Ziegler catalysts and higher alcohols, or as a reducing agent alkylating agent, and is also used in the production of pure metal aluminum using a pyrolysis reaction. In many cases, aluminum aluminum leaks from piping attached to storage tanks, and comes into contact with air and spontaneously ignites. Many metals have a fire hazard and most of them burn under certain conditions. Thermal conductivity is a physical factor that determines combustion. It is very rare for large metals to burn in mass. Highly active metals such as K, Na and Mg are not. Al, Fe, and the like are difficult to burn since heat dissipation by heat conduction is faster than reaction heat, and thus temperature rise is difficult. However, when these metals are also in a subdivided state, the surroundings are accumulated in the air, reducing the thermal conductivity, and at the same time, the contact area with oxygen is increased, thereby increasing the reaction rate per unit area, thereby facilitating combustion. Acceleration is the contact between moisture or moisture in the air and carbon dioxide gas, and the alkali metal element reacts with oxygen, water vapor and C02 in the air to form a surface coating of oxides and carbonates to isolate the air so that no rapid reaction occurs at room temperature. Belonging to alkali metals are very chemically active and susceptible to oxidation. Especially in contact with water it reacts violently to release hydrogen gas. At that time, hydrogen gas may ignite due to the heat generated violently. And with respect to moisture, it is accompanied by a rapid heat generation and flammable gas combustion.

Alkaline metal elements such as Be, Ca, Mg and Sr rarely react directly at room temperature. However, when a large amount of fine powder exists, it may oxidize and generate heat in contact with moisture in the air, thereby gradually increasing the temperature and spontaneously igniting. Al, Zr, Zn, Fe, Mn, Su and these alloys also have no risk of spontaneous ignition in the agglomerate state, but may be generated by moisture or heat in the air when present in large quantities in powder form. Reduced iron and reduced nickel ignite when they come into contact with air and become oxides. They are widely used as catalysts, which can be released with the gas and ignite. Nuclear fission metals widely used in the nuclear industry include uranium, plutonium, thorium, and the like. Magnesium powder is particularly easy to ignite among metal powders, and oxidizes and ignites when it is in damp air. Also in magnesium alloy, when magnesium is large, it may ignite by small heating, abrasion, etc. In the case of aluminium powder, the oxidation rate is slow and the thermal conductivity is large, so the heat storage is low and the risk of ignition is small. However, in the case of fine or porous state, the contact area with air is large and oxidative heat generation often leads to ignition. If aluminum powder is in contact with lead oxide, even if it gives a small ignition source, it causes thermite reaction and generates severe heat. However, micrometals composed of rare earth elements have a flash point between 130 and 150 degrees C and are safe at room temperature and in contact with water.

      Third, it should be harmless to human body when smoking. Rare earth element is harmless to human body because it is physiologically inert.

      When mixed with a suitable amount of rare earth element powder with cigarette powder or included in tobacco paper, it can cause a small and igniting effect safely and harmlessly when smoking, inducing visual and auditory stimuli.

       Agglomerated micrometallic alloys composed of rare earth elements are crushed or ground into fine powders to make powders of constant size. The powder is suitably sized from 50 to 300 micrometers. The general cigarette is divided into a body part and a filter part. The body part is divided into a tobacco part and a cigarette paper, and the filter part is subdivided into a filter and a filter paper. However, in the present invention, the composition of the invention belongs to the manufacturing process of tobacco paper (cigarette paper).
