Mask Protection from a haze while shipping and storage

摘要

We searched for low-outgassing and electroconductive polymer, found that polycarbonate with carbon fiber (PC+CF) was good material as mask case. The amount of gas generation from PC+CF was less than 1/10 of the conventional PMMA material. We also measured the performance of chemical absorbent (PureAID~R) too. This absorbent was effective in removing generated carbon gas from the case and penetrated acid, base and carbon (ABC) gasses into it. The PureAID~R mainteined clean condition in the case while shipping and storage. Functional filter was designed for mask shipping by air plane. The functional filter removed more than 90% ABC gasses. We recommend that the case for mask protection from a haze should adopt low-outgassing polymer composition, chemical absorbent and functional filter. RSP6025-A mask shipper and new concept of RSP150 are adopted these items.
