由于硅橡胶薄膜的透气性比聚乙烯薄膜和聚氯乙烯薄膜高,CO_2、O_2和N_2的透性比为12:2:1,透过乙烯的能力也较强。因此,根据一定的贮量和温度条件,在塑料薄膜贮藏密封系统上镶嵌一定面积的硅橡胶薄膜(简称硅膜),形成硅膜气体交换窗(简称硅窗),使系统中的O_2和CO_2维持在一定范围内,从而免去气调贮藏的许多昂贵设备和烦杂
As the permeability of silicone rubber film is higher than that of polyethylene film and polyvinyl chloride film, the permeation ratio of CO 2, O 2 and N 2 is 12: 2: 1, and the ability to permeate through ethylene is also stronger. Therefore, a certain area of silicon rubber film (referred to as silicon film) is inlaid on a plastic film storage sealing system according to a certain storage and temperature conditions to form a silicon membrane gas exchange window (hereinafter referred to as silicon window) to make O 2 and CO 2 Maintained within a certain range, thus eliminating the many expensive gas storage equipment and complicated
