1) impregnation and compression petroleum coke
浸渍压密石油焦
2) compressed petroleum coke
压密石油焦
1.
A test is done on pre-baked anode made from calcined coke in aspects of apparent density,real density,porosity,resistivity of powder,compressive strength,which shows compressed petroleum coke improves its chemical and physical performances.
采用压密煅烧石油焦制成预焙阳极,通过体积密度、真密度、显气孔率、电阻率、耐压强度、透气度的测试,结果表明,压密石油焦能显著地改善预焙阳极的理化性能,使预焙阳极制造过程中沥青加入量控制在13%,预焙阳极的体积密度达到1。
4) impregnation sealant
浸渍密封
1.
A kind of heat-resistant material-polyimide was chosen as impregnation sealant,and the proper impregnating and solidifying methods were used,through which the graphite rings could be efficiently impregnated twice and after solidifying, polyimide was obtained with heat-resistance (obvious heat-degradation was not observed at 450℃).
选择耐高温的高分子材料———聚酰亚胺作为浸渍密封剂，采用二次真空、加压浸渍工艺和适当的固化方法，既能使聚酰胺酸有效地浸渍石墨环，又能使固化后得到的聚酰亚胺具有最佳耐高温性（在４５０℃没有明显的热解现象）。
5) graphite Impregnation
