粘结剂组成对粘结剂和喂料热性能的影响

Influences of Binder Constituent on Thermal Properties of Binder and Feedstock

摘要:

研究制备了PW，BO，OP3大系列10种组成的粘结剂及相应10种W-Ni-Fe粉末与粘结剂的混合料。并采用热失重-差热分析(TGA-DTA)分析了粘结剂和喂料的热性能。研究结果表明，粘结剂组成对粘结剂和喂料的热性能如熔点、热分解温度和热分解曲线有很大的影响。通过此变化可以更为准确地确定不同粘结剂组成的喂料中的粘结剂脱除工艺和脱除方式。

Abstract:

PW, BO, OP three series of binders containing ten different constituents and ten corresponding binder -powder mixtures were prepared. TGA-DTA thermal analysis was used to investigate binder and feedstock properties. The results show that in the binder system, organic polymer component and content have a great influence on the thermal properties of binder and feedstock such as binder melting point, decomposition temperature degradation curves. The thermal behavior can exactly determine the debinding way and process of the binders.
