一、概述硅橡胶是一种有机硅的高分子聚合物。由于硅橡胶薄膜对 O_2与 CO_2具有优越的透气性和适当的透气比以及能排出多种有害气体等特性。因此,近年来国内外已较广泛地应用硅橡胶气调袋来储藏果品、蔬菜,均取得了良好的效果,但是,到目前为止,尚未见到硅橡胶薄膜应用于粮食储藏方面的技术资料报导。从1978年开始,我国上海、北京、天津、新疆、辽宁等地区相继应用硅橡胶薄膜作为气调窗(以下简称为硅窗)的方法和储藏果品、蔬菜,已取得较好的成效。1979年上海市粮食部门也应用硅窗对大米进行尝试,结果表明,对储藏大米的气体组分有一定的选择性。1982
First, an overview Silicone rubber is a silicone polymer. As the silicone rubber film O_2 and CO_2 have superior permeability and appropriate ventilation ratio and can emit a variety of harmful gases and other characteristics. Therefore, in recent years, silicone rubber gas-filled bags have been widely used at home and abroad for storing fruits and vegetables, and good results have been achieved. However, up to now, no technical information on the application of silicone rubber films for food storage has been reported . Since 1978, the method of using silicone rubber film as tone window (hereinafter referred to as silicon window) and the storage of fruits and vegetables in Shanghai, Beijing, Tianjin, Xinjiang and Liaoning have achieved good results. In 1979, the grain department of Shanghai Municipality also applied silicon windows to try rice, and the results showed that it has certain selectivity to the gas components of stored rice. 1982
