国内外主要的ODS替代品有HFC—134a、120系列产品、HFC-32、HFC-152a等。其中HFC-134a广泛用于汽车和冰箱行业,全球生产能力达到19.4万t/a,我国市场消费量已经超过1000t/a。目前国内还没有开展全面的ODS替代工作,所以用量不大,几乎全部依赖进口。随着2010年停用ODS期限的临近,国内应从市场调研、产品开发等各方面做好建设ODS替代品项目的工作。
Major ODS substitutes at home and abroad are HFC-134a, 120 series products, HFC-32, HFC-152a and so on. Among them, HFC-134a is widely used in the automobile and refrigerator industries and has a global production capacity of 194,000 t / a. The consumption in China’s market has exceeded 1,000t / a. At present, China has not carried out comprehensive ODS alternative work, so the amount is not large, almost all rely on imports. As the deadline for deactivating the ODS is approaching in 2010, domestic efforts should be made to build ODS alternatives from market research and product development.
