摘要
介绍了用原位凝固注模成形法制备铁-莫来石复合材料坯体的基本工艺过程,研究了复合材料浆料的固相含量、原位凝固剂等对坯体性能的影响。结果表明,原位凝固剂可使浆料原位凝固,通过调节固相含量、凝固剂、缓冲剂可以控制凝固时间和坯体的强度,坯体具有密度较高且均匀,足够的脱模强度,尺寸变化率小等特点。
The basic processing of Fe 3Al 2O 3·2SiO 2 composite green by in situ coagulation in slip casting is reported.The influences of the solid content and coagulant in composite slurry on the properties of composite green body are investigated.The results show that the in situ coagulation of composite slurry is facilitated by the coagulant.By changing the contents of solid,coagulant and buffer in composite slurry,the coagulation time and strength of composite green body can be adjusted.The composite green body is characterized by high density and homogeneity,sufficient ejection strength and little dimensional change rate.
