Example Embodiment
[0040] Example 2
[0041] The odor evaluation device is the same as in Example 1. The steps of the method of use are:
[0042] a. The inner volume of heating device 1 is 2m 3 Place the parts to be tested in the sample bag 2 of the sample bag, use the bead 7 and the pressure groove 8 to clamp the opening 6 of the sample bag 2 tightly, keep the air valve 4 open, and connect the vacuum pump to the end of the outer air pipe 3 of the heating device 1 Vacuum bag 2;
[0043] b. Fill the sample bag 2 with 1.6m 3 For high purity air, close valve 4;
[0044] c. Turn on the heating device and raise the temperature to 65°C for 6h;
[0045] d. Turn off the heating device 1, open the gas valve 4, and connect the end of the gas pipe 3 to a suction pump to export the gas to be tested in the sample bag 2 for odor evaluation.
Example Embodiment
[0046] Example 3
[0047] The odor evaluation device is the same as in Example 1. The steps of the method of use are:
[0048] a. The internal volume of heating device 1 is 3m 3 Place the parts to be tested in the sample bag 2 of the sample bag, use the bead 7 and the pressure groove 8 to clamp the opening 6 of the sample bag 2 tightly, keep the air valve 4 open, and connect the vacuum pump to the end of the outer air pipe 3 of the heating device 1 Vacuum bag 2;
[0049] b. Fill the sample bag 2 with 2.4m 3 For high purity nitrogen, close valve 4;
[0050] c. Turn on the heating device and raise the temperature to 100°C for 2h;
[0051] d. Turn off the heating device 1, open the gas valve 4, and connect the end of the gas pipe 3 to a suction pump to export the gas to be tested in the sample bag 2 for odor evaluation.
