除气对制备等静压石墨的影响研究

Degassing effect on the preparation of isostatic graphite

等静压石墨生产中,除气是一步重要的环节,它对成型工艺、压坯性能有较大的影响。本文针对冷/热等静压法生产特种石墨,主要从压坯的形貌、体积密度、显气孔率和抗压强度来分析除气对工艺和产品质量的影响。

During manufacture of isostatic graphite,degassing is an important part,which has great influence on molding process and compact performance. In this paper, the effects of degassing on the compact morphology, bulk density, apparent porosity and compressive strength of the cold/hot isostatic pressing manufacture special graphite were discussed.
