中国过去 10余年安排的一批科研开发项目相继完成 ,先后进入中试及工业化试验阶段 ,投放市场的臭氧消耗物质 (ODS)替代品品种不断增多 ,形成较为齐全的产品系列。ODS替代品的装置生产能力扩大 ,产量急增 ,其中臭氧损耗潜值 (ODP) <0 0 5的ODS替代品的产能增加较快。我国具有自主知识产权的混合工质品种不断推出 ,全球变暖潜值 (GWP)值低的ODS替代品将得到更快的发展。 A batch of R & D projects arranged by China over the past 10 years have been completed one after another. They have successively entered the pilot and pilot phase of industrialization. The number of substitutes for ODS put on the market continues to increase, forming a complete product line. ODS alternatives have expanded their capacity and output soared, with ODS replacements with ODP <0 0 5 increasing rapidly in capacity. Our country has independent intellectual property rights of mixed working medium varieties are introduced, low global warming potential (GWP) value of ODS substitutes will get faster development.
