Abstract

This paper presents the use of ashes from brown coal combustion (BCA) as fillers in rubber mixtures, to reduce the emission of volatile organic compounds. Two types of ash, BCA1 and BCA2, were selected as fillers for styrene-butadiene rubber (SBR). The ashes were produced during the treatment of brown coal at the Bełchatów Power Plant in the years 2017 and 2018. The morphology and chemical composition of the ash were tested. Morphology studies using scanning microscopy showed differences in the grain sizes of the ashes, and EDS analysis showed a difference in their chemical compositions. Vulcanizates with different weight proportions of the individual ashes were produced. Mixtures were made with the addition of 10-30 pts. wt. ashes per 100 g of SBR. The addition of BCA1 ash at 10 and 30 pts. wt. reduced the emission of volatile organic compounds (VOC) while maintaining the good strength properties of the mixtures.

摘要

本文介绍了将褐煤燃烧产生的灰烬（BCA）用作橡胶混合物中的填料，以减少挥发性有机化合物的排放。选择了两种类型的灰烬BCA1和BCA2作为丁苯橡胶（SBR）的填料。这些灰烬是2017年和2018年在贝乌哈托夫发电厂处理褐煤期间产生的。对灰烬的形态和化学成分进行了测试。使用扫描显微镜进行的形态学研究显示了灰烬粒度的差异，而能谱分析显示了它们化学成分的差异。制备了具有不同重量比例的各灰烬的硫化橡胶。每100克SBR添加10 - 30重量份的灰烬制成混合物。添加10和30重量份的BCA1灰烬可减少挥发性有机化合物（VOC）的排放，同时保持混合物良好的强度性能。
