由于有机物的吸收,在一般室内环境中长时间(几个月)存放的膜通常会变暗/变褐色。在储存期间,应确认产品是否保持密封。
· 保持膜密封并防止一般暴露,可减少有机物的影响。长期储存时,建议使用密封袋存放。
· 变色不影响性能,使用稀硝酸浸泡可除去颜色。
采用具有热封箔衬袋的平整信封包装

储存及稳定性

Storage is to keep sealed in bag. After opening, storage of more than 1 year could cause yellow coloring of the membrane. Simple 1/2 hr soak in De ionized water is all that is needed prior to most uses.
