摘要： The invention discloses a starch-based multi-channel airflow unit and a preparation method and an application thereof. The preparation method of the present invention comprises the following steps: melting a polylactic acid, wherein a temperature of a first temperature control zone is 135°C to 145°C, a temperature of a second temperature control zone is 175°C to 185°C, a temperature of a third temperature control zone is 190°C to 200°C, and a temperature of a fourth temperature control zone is 175°C to 185°C; gelatinizing a starch-based material, adding the starch-based material in the third temperature control zone and fully mixing the mixture; adding a polyol in the third temperature control zone, and fully mixing the mixture; and extruding out the mixed material through twin screws, sizing in vacuum, cooling and sizing, and winding and cutting to obtain the starch-based multi-channel airflow unit. According to the preparation method of the present invention, a damage of a molecular structure of the polylactic acid in a melting and mixing process is reduced by sizing a specific temperature for heating in the four zones in the material melting and mixing process, so that polylactic acid molecules are sufficiently molten but not decomposed, thus achieving an effect of stable structure. The prepared starch-based cooling material has an excellent thermoplastic performance, is convenient for processing and molding, has an excellent strong cooling effect and can have a cooling effect of 120°C.

摘要： The invention provides a heat-not-burn cigarette product. The heat-not-burn cigarette product of the invention includes a cigarette product and a heater in matched use with the cigarette product. A sucking resistance when the cigarette product and the heater in matched use with the cigarette product are used together is P 1 , and a sucking resistance of the cigarette product is P 2 , wherein a ratio of P 2 /P 1 is greater than or equal to 50%. By controlling a total sucking resistance when the cigarette product and the heater in matched use with the cigarette product are used together, a sucking resistance of each part and a proportional relationship between the sucking resistance of each part and the total sucking resistance, a sucking sense of the heat-not-burn cigarette product according to the invention is greatly improved. The sucking resistance of the cigarette product in the heat-not-burn cigarette product of the invention accounts for more than 50% of the total sucking resistance of the heat-not-burn cigarette product, thus realizing optimized design of an air channel and proper supply of air, realizing balance between the sucking resistance and a smoke amount, and improving a sucking feeling. A sucking resistance of a tobacco section accounts for 40% to 80% of a sucking resistance of a cigarette product section, thus achieving effects of sufficient smoke amount and low interception.
