VOCs abatement evaluation of supercritical carbon dioxide green spraying in industrial surface coating

  • 摘要: 工业企业VOCs源头减排是“十五五”期间空气质量改善的重点工作任务。超临界二氧化碳(ScCO2)喷涂技术作为同时减少涂料中VOCs含量和涂料使用量的VOCs源头减排前沿技术,其在示范应用层面的涂着效率提升情况和VOCs减排效果尚缺乏实证。研究选取了木质家具-聚氨酯、木质家具-丙烯酸、金属件-氟碳3个我国工业涂装行业常见的溶剂型涂料体系,构建了ScCO2喷涂涂着效率、VOCs减排率测算方法,并对其减排效果进行了实测和分析。结果表明:60,40 cm喷涂距离下,3个示范应用场景的ScCO2喷涂与高压无气喷涂相比,平均涂着效率提升率分别为(30.62±8.75)%、(31.74±12.83)%,平均VOCs减排率分别为(62.10±1.59)%、(53.73±11.78)%。在木质家具和金属件涂装工艺中均可实现较为显著的VOCs减排和溶剂减量效果。
