摘　　要：为了改善湿砂造型的生态环境,科莱恩公司推出了一种低排放添加剂技术,可让铸造厂的湿砂系统的BTEX排放量降低到80%,并且可以优化生产效率,使铸件表面粗糙度降低。探讨了当前膨润土湿砂减排的主要技术,以期对这项技术的潜力进行评估,并为铸造厂和相关产业所需的可持续性改进做出贡献。概述了新技术的原理,并解释了公司创新研发的新的检测方法,用于测量和比较在实际铸造工艺条件下此新技术与加光亮碳形成剂的湿型砂的芳烃排放物的比较。最后,展示了低排放添加剂新技术在欧洲铸造厂实际应用中取得的成果。The introduction of a unique low emission additive technology by Clariant, is enabling found- ries to reduce BTEX emissions from green sand systems by up to 80 % and produce highest quality cast- ings with improved surface quality at optimum productivity. To assess the potential of this technology to contribute to the sustainability improvements wanted by foundries and related industries, this article ex- amines the current primary techniques for emission reduction from bentonite--based green sand. It out- lines the principles of the new technology and explains the innovative testing method developed by the company to measure and compare emissions of aromatics from lustrous carbon formers under realistic foundry process conditions. Finally, it shows results achieved in practice in a European foundry using the new low emission additive technology.
