Embodiment 1
[0025] The composition of each component of the porous carbonaceous heat source material in this embodiment is as follows:
[0026]
[0027] The above-mentioned raw materials and 60g water are initially mixed, and then sent into the screw extruder to continue mixing, while blowing agent CO 2 It is poured into an extruder, extruded after foaming, and then dried and cut to obtain a porous carbonaceous heat source material.
[0028] The screw process parameters are set as follows: the temperature is 25-35° C., and the screw speed is 100 rpm.
[0029] Blowing agent CO 2 The injection flow rate is 6mL / min.
Embodiment 2
[0031] The composition of each component of the porous carbonaceous heat source material in this embodiment is as follows:
[0032]
[0033] The above-mentioned raw materials and 100g water are initially mixed, and then sent into the screw extruder to continue mixing, while blowing agent CO 2 It is poured into an extruder, extruded after foaming, and then dried and cut to obtain a porous carbonaceous heat source material.
[0034] The screw process parameters are set as follows: the temperature is 25-35° C., and the screw speed is 150 rpm.
[0035] Blowing agent CO 2 The injection flow rate is 10mL / min.
Embodiment 3
[0037] The composition of each component of the porous carbonaceous heat source material in this embodiment is as follows:
[0038]
[0039] The above-mentioned raw materials and 130g water are initially mixed, and then sent into the screw extruder to continue mixing, while blowing agent CO 2 It is poured into an extruder, extruded after foaming, and then dried and cut to obtain a porous carbonaceous heat source material.
[0040] The screw process parameters are set as follows: the temperature is 25-35° C., and the screw speed is 180 rpm.
[0041] Blowing agent CO 2 The injection flow rate is 16mL / min.
[0042] The carbonaceous heat sources prepared in Example 1, Example 2, and Example 3 were evaluated for three indicators: ignitability, CO release, and combustion shrinkage rate. The results are shown in Table 1.
[0043] It can be seen from Table 1 that the ignition temperature, CO emission and shrinkage rate of the carbonaceous heat source prepared by the present inve...
