摘　　要：粘结型催化剂在制作成型后,其强度发展与原材料、养生期间所处的温度、湿度以及养生方式和时间密切相关。应用不同种类水泥、不同水泥含量制备了粘结型催化剂,分别测定其在不同养生方式、不同养生时长下的强度变化,分析粘结型催化剂养生后强度变化规律。结果表明,在不同方式的养生条件下,催化剂养生前后强度变化表现出明显差异,蒸锅养生方式操作最为简便,效果符合生产需求;在同一种养生条件下,随着养生时间的持续会加大养生前后强度提升的幅度,蒸锅养生(6~8)h效果最佳;通过改变催化剂中水泥含量和在物料混合的早期过程及时采取养生措施,同样可使催化剂强度变化表现出不同规律,可为推荐粘结型催化剂的养生方式等提供理论依据。The strength development of bonded catalysts is influenced by various factors such as raw materials,curing temperature and humidity,curing methods,and curing time.This study investigated the strength changes of bonded catalysts using different cement types and contents under various curing methods and durations.The results revealed significant differences in catalyst strength before and after curing,with steamer curing being the most effective and easiest to operate.Longer curing times led to increased strength enhancement,with optimal results achieved after(6~8)h of steaming.Additionally,adjusting cement content and implementing timely curing measures during the early mixing stage further improved catalyst strength.These findings provide a theoretical basis for recommending curing methods for bonded catalysts,optimizing their performance in various applications.
