Test Purpose:
The air permeability of the outer package was judged by testing the moisture absorption rate of the deodorant desiccant.
Test data:
Sample 1: Deodorant desiccant, the raw material is modified spherical activated carbon, O-cloth packaging, raw material is 25 g/bag, product number is 25-101 BO160-007. The picture is as follows:
Sample 2: Deodorant desiccant, the raw material is modified spherical activated carbon, DuPont paper packaging, 15 g / bag, product number 15-101AG120-009. The picture is as follows:
| Time(Day) | Sample 1(g) | Sample2(g) | ||
| 0 | 24.60 | 24.84 | 15.13 | 15.21 |
| 1 | 27.52 | 27.76 | 16.70 | 16.78 |
| 2 | 28.32 | 28.56 | 17.34 | 17.40 |
| MAX absorption | 15.12% | 14.97% | 14.6% | 14.39% |
| Average absorp | 15.05% | 14.50% | ||
Test result:
The deodorizing desiccant of two different packaging materials with modified spherical activated carbon as raw material, the moisture absorption rate of deodorizing desiccant packaged with SMS non-woven fabric is 15.05% in the same time, except DuPont paper packaging. The moisture absorption rate of the stinky desiccant was 14.50%. It can be seen that the SMS nonwoven fabric has good gas permeability.
