Embodiment 2
[0041] The odor evaluation device is the same as in Example 1, and the steps of the method of use are:
[0042] a. The volume to the heating device 1 is 2m 3 Put the parts to be tested in the sample bag 2, use the bead 7 and the pressure groove 8 to clamp and seal the opening 6 of the sample bag 2, keep the air valve 4 open, and connect the end of the heating device 1 outer air pipe 3 to a vacuum pump to vacuum the sample Bag 2 is vacuumed;
[0043] b. Fill 1.6m into the sample bag 2 3 For high-purity air, close the air valve 4;
[0044] c. Turn on the heating device to raise the temperature to 65°C and keep it for 6h;
[0045] d. Turn off the heating device 1, open the air valve 4, connect the end of the air pipe 3 to an air pump, and export the gas to be tested in the sample bag 2 for odor evaluation.
Embodiment 3
[0047] The odor evaluation device is the same as in Example 1, and the steps of the method of use are:
[0048] a. The volume to the heating device 1 is 3m 3 Put the parts to be tested in the sample bag 2, use the bead 7 and the pressure groove 8 to clamp and seal the opening 6 of the sample bag 2, keep the air valve 4 open, and connect the end of the heating device 1 outer air pipe 3 to a vacuum pump to vacuum the sample Bag 2 is vacuumed;
[0049] b. Fill 2.4m into the sample bag 2 3 For high-purity nitrogen, close the gas valve 4;
[0050] c. Turn on the heating device to raise the temperature to 100°C and keep it for 2 hours;
