数据集使用建议 | 使用此数据集时,确保分析的范围与所涵盖的生产过程—特别是中国的乙烯法—一致。如果建模PVC生产过程,请考虑该数据可能会整合中国数据不足时的欧洲来源信息。特别注意电力输入,该输入基于中国的国家电网结构,反映了2020年的电力结构数据。为了进行一致的环境影响评估,采用了ReCiPe方法(欧洲H/H)。在推断结果时重要的是保持已定义的功能单位为1公斤树脂生产,以便可以可靠地比较不同的数据集。 |
产品或过程的技术目的 | 该数据集代表了中国使用乙烯法生产的聚氯乙烯(PVC)。通过此方法生产的PVC通常用于包括管材和配件在内的建筑材料、电线电缆制造、消费品和医疗设备等多种应用。该数据集评估了由乙烯和电石工艺生产的PVC的环境影响。 |

时间代表性描述 | Process-based data from China were used, yet if not available, data from Europe were applied instead. The electricity input was developed based on the national grid structure in China (Table S3), which was obtained from the share of the electric power structure in 2020 (National Bureau Statistics of China, 2020). |
