干洗织物,皮革用的有机溶剂干洗剂以往多采用卤代烃CFC—113。此化合物对臭氧层有较大破坏作用。当今,保护臭氧层的呼声越来越高,干洗过程中CFC—113的泄漏问题亟待解决。 本文介绍一种成本低、工艺简单、不破坏环境的干洗方法。其关键是:(1)以对臭氧层影响很小的第二代卤代烃—— In dry-cleaning fabrics, dry-cleaners for organic solvents used in leather, CFC-113 was often used. This compound has a greater damaging effect on the ozone layer. Nowadays, the ozone layer protection is getting louder and louder and the issue of CFC-113 leakage in the dry cleaning process needs to be solved urgently. This article describes a low cost, simple process, does not damage the environment dry cleaning methods. The key is: (1) With a second generation halohydrocarbon, which has little effect on the ozone layer,
