The invention provides a thermal insulation material for combustion type heating cigarettes as well as a preparation method and application of the thermal insulation material. The thermal insulation material comprises the following components: aerogel particles, hollow glass beads, ceramic fibers and expanded graphite. When the thermal insulation material is applied to combustion type heating cigarettes, the thermal insulation environment can be effectively constructed, the thermal loss of the cigarettes is reduced, the thermal uniformity and the utilization efficiency are improved, and finally the technical effect of more complete carbonization of cigarette core materials is achieved.

The invention provides a resistance-adjustable heating plate preparation method and application thereof, and the method comprises the following steps: dispersing a porous graphene-carbon nanotube hybrid in a solvent, adding an organosilicon polymer precursor, and carrying out mixing and grinding to obtain a slurry; the slurry is coated on a substrate to form a coating area, at least one high-temperature sintering area and at least one low-temperature sintering area are arranged in the coating area, the high-temperature sintering area and the low-temperature sintering area are sintered in different areas, and the sintering temperature of the high-temperature sintering area is higher than that of the low-temperature sintering area; and obtaining the heating plate. According to the preparation method of the heating plate with the adjustable resistance, provided by the invention, the slurry is prepared from the porous graphene-carbon nanotube hybrid and the organosilicon polymer precursor, a uniform conductive network is formed by virtue of the porous structure of the hybrid, and the film forming and bonding strength is guaranteed; partitioned sintering is carried out in the same coating area, high and low surface resistance areas are formed by using temperature difference, thermal stress is reduced by the integrated conductive layer, and the reliability of the heating plate is remarkably improved while the process is simplified.

This invention discloses a pressure calcination process for producing high-purity graphite, relating to the field of graphite production technology, including the following steps: S1, mixing graphite raw materials with a binder; S2, placing the graphite raw materials containing the binder into a mold on a placement platform, and then placing the placement platform and the mold together into a calcination furnace; This invention uses a designed flipping mechanism to drive the mold to flip, realizing the exchange of positions between the upper and lower layers of graphite raw materials, allowing the previously underheated bottom raw materials to directly receive infrared radiation from the resistance wire, eliminating temperature gradients, improving calcination uniformity, and simultaneously working with a transparent pressure plate to compact and flatten the graphite raw materials in the mold before and after flipping, ensuring uniform heating for more complete carbonization of the binder, resulting in consistent density of the green body, and promoting the full volatilization of impurities in various areas of the raw materials, laying the foundation for subsequent graphitization, and improving the purity and quality stability of high-purity graphite products.
