Description
本发明属于加热不燃烧卷烟加工技术领域。更具体地，本发明涉及一种用于磁粒均热的感应加热材料。The invention belongs to the technical field of heat-not-burn cigarette processing. More specifically, the present invention relates to an induction heating material for soaking magnetic particles.
传统的卷烟需要通过明火点燃燃烧香烟，卷烟在高温燃烧过程中会释放近6000种对人和周围环境有害的物质，这些有害成分经烟气被人体吸收后会危害吸烟者和周围人群的健康。有研究表明，尼古丁和多数烟草香味成分在低温度下(300-500℃)就可以转移到烟气中，降低烟草燃烧裂解温度，在保持发烟基质满足生理满足感和香气的同时，可使烟气多种有害成分可以大幅度降低。加热不燃烧卷烟就是利用特殊热源对烟丝进行加热，加热的温度最高不超过500℃，烟气有害化学成分和生物毒性大幅降低，从而显著减少了对人体和环境的危害。Traditional cigarettes need to be ignited and burned through an open flame. During the high-temperature combustion process, the cigarette releases nearly 6,000 substances harmful to people and the surrounding environment. These harmful components are absorbed by the human body and endanger the health of smokers and surrounding people. Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at low temperatures (300-500°C), lowering the temperature of tobacco burning and pyrolysis, and keeping the smoking matrix to meet physiological satisfaction and aroma while making Many harmful components of flue gas can be greatly reduced. Heat-not-burn cigarettes use special heat sources to heat cut tobacco. The heating temperature does not exceed 500°C. The harmful chemical components and biological toxicity of the smoke are greatly reduced, thereby significantly reducing the harm to the human body and the environment.
加热不燃烧卷烟烟草制品根据加热方式的不同，可分为电阻加热型、理化反应加热型、燃料加热型等，均是不需要燃烧只是通过加热烟丝，烘烤出烟草中的尼古丁和香味物质，来满足吸烟者的需求。目前市面主要是以电阻加热型为主，传热效率低，加热完成后腔体中残留物质多，影响抽吸口感，并且连续抽吸后加热器温度急剧升高，有爆炸的风险。Heating non-burning cigarettes Tobacco products can be divided into resistance heating type, physicochemical reaction heating type, fuel heating type, etc. according to different heating methods. All of them do not need to be burned, but the nicotine and flavor substances in the tobacco are baked by heating the tobacco. To meet the needs of smokers. The current market is mainly based on the resistance heating type, which has low heat transfer efficiency. After the heating is completed, there are many residual substances in the cavity, which affects the suction taste, and the heater temperature rises sharply after continuous suction, and there is a risk of explosion.
电磁感应加热，是通过电子线路板组成部分产生交变磁场，对应金属表面切割交变磁力线从而产生交变的电流(即涡流)，涡流使金属原子高速无规则运动，原子互相碰撞、摩擦而产生热能，起到加热物品的效果，热效率可达95％，烟枪无需清洁，加热器的热量均被感应加热材料和发烟段所带走不存在加热器发烫问题。但是目前电磁感应加热技术，由于在交变磁场中发烟基质的感应加热材料为常规的铁素材料，铁素的居里温度为769℃，在加热过程中一致加热直至769℃，抽吸几口后，会出现焦胡味，极大的影响了抽吸口感，导磁性感应加热材料的居里温度会影响发烟段的加热温度，导致发烟段受热不均，温度不宜控制，大大降低消费者的消费体验。Electromagnetic induction heating generates an alternating magnetic field through the components of the electronic circuit board, which cuts the alternating magnetic field lines corresponding to the metal surface to generate alternating currents (ie eddy currents). The eddy currents cause the metal atoms to move randomly at high speeds, and the atoms collide and rub against each other. The heat energy has the effect of heating the object, the thermal efficiency can reach 95%, the smoke gun does not need to be cleaned, the heat of the heater is taken away by the induction heating material and the smoking section, and there is no problem of the heater being hot. However, the current electromagnetic induction heating technology, because the induction heating material of the smoking substrate in the alternating magnetic field is a conventional ferrite material, the Curie temperature of ferrite is 769℃, and it is heated up to 769℃ in the heating process. After the mouth, a burnt smell will appear, which greatly affects the taste of the suction. The Curie temperature of the magnetic induction heating material will affect the heating temperature of the smoking section, resulting in uneven heating of the smoking section, and the temperature is not suitable for control, which greatly reduces Consumer experience.
因此，针对现有技术的诸多技术缺陷，本发明人通过调整电磁感应加热的导磁性金属感应加热材料，进行了大量的试验与分析，终于完成了本发明。Therefore, in view of many technical shortcomings of the prior art, the inventors conducted a lot of experiments and analyses by adjusting the magnetic metal induction heating material heated by electromagnetic induction, and finally completed the present invention.

在本发明中，所述的基体材料、导磁性金属与耐高温导磁性非金属的重量比是1.0：0.2～1.0：0.2～0.5。基体材料与耐高温导磁性非金属用量在所述范围内时，如果导磁性金属的用量低于0.2，则会磁感体感应能力不足，加热效率偏低；如果导磁性金属的用量高于1.0，则会导致成本上升；因此，导磁性金属的用量为0.2～1.0是合理的，优选地是0.4～0.8；同样地，基体材料与导磁性金属用量在所述范围内时，如果耐高温导磁性非金属的用量低于0.2，则会影响加热的均匀性；如果耐高温导磁性非金属的用量高于0.5，则会磁感体感应能力不足，加热效率偏低；因此，耐高温导磁性非金属的用量为0.2～0.5是恰当的，优选地是0.2～0.4。In the present invention, the weight ratio of the base material, the magnetic metal and the non-metal with high temperature resistance is 1.0:0.2-1.0:0.2-0.5. When the amount of the base material and the non-metallic non-metallic material with high temperature resistance is within the stated range, if the amount of the magnetic metal is less than 0.2, the induction capacity of the magnetic sensor will be insufficient and the heating efficiency will be low; if the amount of the magnetic metal is higher than 1.0 , It will lead to an increase in cost; therefore, it is reasonable for the amount of magnetic metal to be 0.2 to 1.0, preferably 0.4 to 0.8; similarly, when the amount of base material and magnetic metal are within the range, if the If the amount of magnetic nonmetal is less than 0.2, it will affect the uniformity of heating; if the amount of high temperature resistant magnetic nonmetal is higher than 0.5, the induction capacity of the magnetic sensor will be insufficient, and the heating efficiency will be low; therefore, high temperature resistant magnetic permeability The amount of non-metal is 0.2-0.5, preferably 0.2-0.4.
根据本发明，被所述耐高温导磁性非金属包裹的导磁性金属均匀地分散在所述的基体材料中，其包裹方法参见文献CN 201610385850、发明名称《一种复合功能磁条及其制备方法》。所述耐高温导磁性非金属包裹层厚度是0.2～1.0mm。如果耐高温导磁性非金属包裹层厚度超过所述的范围是不可取的，因为包裹层过厚则影响加热效率，包裹层过薄则影响加热的均匀性。According to the present invention, the magnetically permeable metal wrapped by the high-temperature-resistant magnetically permeable non-metal is uniformly dispersed in the matrix material. For the wrapping method, see document CN 201610385850, the name of the invention "a composite functional magnetic strip and its preparation method ". The thickness of the high-temperature resistant and magnetically permeable non-metal coating layer is 0.2 to 1.0 mm. It is not advisable if the thickness of the non-metallic coating with high temperature resistance and magnetic permeability exceeds the stated range, because too thick the coating will affect the heating efficiency, and too thin the coating will affect the uniformity of heating.
或者，所述的导磁性金属以点、线、条或其它规则形状方式镶嵌在所述的耐高温导磁性非金属材料表面上，其镶嵌方法参见文献CN201310050678、发明名称《用于固定地紧固金属镶嵌物的装置》。镶嵌在耐高温导磁性非金属材料表面上的导磁性金属量是0.002～0.01g/mm
2。如果导磁性金属量低于0.002g/mm
2，则生产成本过高；如果导磁性金属量高于0.01g/mm
2，则有效的感应材料质量不足，加热效率低；因此，导磁性金属量为0.002～0.01g/mm
2是合适的，优选地是0.004～0.008g/mm
2；其导磁性金属量测定方法参见文献李东、熊倩，《一种非铁磁性金属上非铁磁性金属涂镀层厚度的测量方法》，《无损检测》，2018年2月。根据本发明，所述的感应加热材料呈棒、片或颗粒形状。当然，所述的感应加热材料也可以为其它的形状，只是它们的最大宽度应该小于卷烟直径，而长度短于发烟基质发烟段。
Alternatively, the magnetically permeable metal is embedded on the surface of the high-temperature-resistant magnetically permeable non-metal material in a manner of dots, lines, bars or other regular shapes. For the inlay method, see document CN201310050678, the name of the invention "For fixed fastening Installation of metal inlays. The amount of permeable metal embedded on the surface of the non-metallic material with high temperature resistance is 0.002～0.01g/mm 2 . If the amount of permeable metal is less than 0.002g/mm 2 , the production cost is too high; if the amount of permeable metal is higher than 0.01g/mm 2 , the effective induction material quality is insufficient and the heating efficiency is low; therefore, the amount of permeable metal 0.002～0.01g/mm 2 is suitable, preferably 0.004～0.008g/mm 2 ; the method for determining the amount of magnetic metal content can be found in the literature Li Dong and Xiong Qian, "A Non-ferromagnetic Metal on a Non-ferromagnetic Metal Method for Measuring Coating Thickness, "Non-destructive Testing", February 2018. According to the present invention, the induction heating material is in the shape of rods, sheets or particles. Of course, the induction heating materials can also have other shapes, but their maximum width should be smaller than the diameter of the cigarette, and the length should be shorter than the smoking section of the smoking substrate.
根据非接触式红外辐射温度测量标准方法检测，本发明感应加热材料的居里温度为290～500℃。其居里温度超过所述的范围是不可取的，这是因为如果居里温度低于290℃则会导致本发明装置达不到使被加热烟草材料释放烟气所需要的温度条件，而居里温度超过500℃则会烟草原料发生燃烧，导致设备过热而使消费者难以承受。According to the non-contact infrared radiation temperature measurement standard method, the Curie temperature of the induction heating material of the present invention is 290-500°C. It is undesirable for the Curie temperature to exceed the stated range. This is because if the Curie temperature is lower than 290°C, the device of the present invention will not reach the temperature conditions required for the heated tobacco material to release smoke. If the internal temperature exceeds 500°C, the tobacco raw materials will burn, causing the equipment to overheat and making it unbearable for consumers.
本发明的感应加热材料应用于控制发烟基质感应加热材料中。The induction heating material of the present invention is applied to the induction heating material for controlling the smoking substrate.
优选地，所述的感应加热材料均匀地分散在发烟基质中。将所述的感应加热材料均匀地分散在加热不燃烧发烟基质中，得到磁粒均热的加热不燃烧卷烟。根据《YC_T 138-1998_烟草及烟草制品感官评价方法》标准规定组织评吸专家进行评吸，其评吸结果列于下面的表1中。Preferably, the induction heating material is uniformly dispersed in the smoking matrix. The induction heating material is uniformly dispersed in the heating non-combustion smoking matrix to obtain the heating non-combustion cigarette with uniform heating of magnetic particles. According to the standards of "YC_T 138-1998_ Sensory Evaluation Method for Tobacco and Tobacco Products", evaluation experts are organized to conduct evaluations. The evaluation results are listed in Table 1 below.
同时，使用中心加热元件的HNB烟草烟弹作为对照样品也进行了评吸，其评吸结果也列于表1中。At the same time, the HNB tobacco cartridge using the central heating element as a control sample was also evaluated, and the evaluation results are also listed in Table 1.
