The PVC produced using the calcium carbide process is used in various applications in the plastics industry. It can be utilized in the manufacturing of construction materials, piping, cable insulation, flooring, and other PVC-related products that require specific properties imparted by the calcium carbide method. 采用电石法生产的PVC可用于塑料工业中的各种应用。可用于建筑材料、管道、电缆绝缘、地板及其他需要电石法特定属性的PVC相关产品的制造。 Q6TxbJsPGooDczxnxKCcQKbmnHc.png Unit process, black box None 无 None 无 None 无 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). None 无 ReCiPe method (Europe H/H) was used as the assessment method for consistency. None 无 An, J., Wu, F., Wang, D. & You, J.

Resources, Conservation and Recycling 180, (2022). When using this LCA data set for PVC produced by the calcium carbide method, ensure to account for the methodological differences between data sourced from China and Europe. Be attentive to the fact that electricity input is modeled based on China's national grid structure of 2020. If the data set cannot fulfill regional specific conditions, it might be less accurate. The ReCiPe method (Europe H/H) should be employed for impact assessment, ensuring methodological consistency. Consider 1 kg of resin production as the functional unit for your assessments. 在使用电石法生产PVC的生命周期评价(LCA)数据集时，确保考虑了来自中国和欧洲数据源的方法论差异。注意电力输入是基于2020年中国国家电网结构建模的。如果数据集不能满足特定地区条件，可能会降低其准确性。应使用ReCiPe方法（欧洲H/H）进行影响评估，确保方法论的一致性。将1公斤树脂生产作为你评估的功能单位。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Huijuan Guo, GHJ@email.ncu.edu.cn 郭慧娟, GHJ@email.ncu.edu.cn GHJ@email.ncu.edu.cn GHJ@email.ncu.edu.cn 2024-04-19T20:02:03+08:00 2024-04-20T14:47:26.937120+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=3d95ab31-54d9-478e-8ee7-6ee5c1fb19d7&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses hydrogen chloride Input 2.05 2.05 Missing unimportant Hydrochloric acid Hydrochloric acid acetylene Input 0.44 0.44 Missing unimportant Process water Input 0.58 0.58 Missing unimportant Processed water Processed water Electricity Input 0.62 0.62 Missing unimportant process steam Input 4.52 4.52 Missing unimportant Steam Steam polyvinylchloride resin (B-PVC) Output 1.0 1.0 Missing unimportant PVC PVC ethylene Output 4.4e-08 4.4e-08 Missing unimportant chemical oxygen demand Output 0.00147 0.00147 Missing unimportant mercury Output 1e-09 1e-09 Missing unimportant Waste (unspecified) Output 10.0 10.0 Missing unimportant Acid Gases Output 12.5 12.5 Missing unimportant Acid gases Acid gases Dust Output 0.00095 0.00095 Missing unimportant Dust Dust
