摘要
氯氟烃的生产和使用已经被禁止,由于氢氯氟烃的臭氧消耗潜值和全球变暖潜能值而正在被淘汰。LBA是第四代发泡剂,它的臭氧消耗潜值为0,全球变暖潜能值很小。我们系统地研究了LBA在冰箱领域的应用。我们通过筛选聚醚和催化剂的种类,并调节水分含量来获得合适的配方。实验结果表明文中的LBA组合聚醚的性能超过了HFC-245fa的组合聚醚性能。
The production and use of CFCs are banned,HCFCs are being phased out due to its ODP and GWP.LBA is a fourth generation blowing agents. The ODP of LBA equal to zero and its GWP is very low. The application of LBA in refrigerator industry was systematically studied. Polyethers or catalysts was selected,and adjusted the moisture content to get a suitable formulation. The result showed that the property of the prepared LBA premixed polyether surpassed the property of HFC-245 fa premixed polyether.
