Preparation method of carbon fiber reinforced porous graphite separator
The invention discloses a preparation method of a carbon fiber reinforced porous graphite partition plate. Needle coke with the size of 50-200 microns, phenolic resin, pore-forming agent ammonium bicarbonate and carbon fibers which are strictly controlled are used; the preparation method comprises the following steps: weighing needle coke, phenolic resin, pore-forming agent ammonium bicarbonate and carbon fibers according to specifications, putting the weighed materials into a three-dimensional mixer, mixing and stirring the materials, then putting the uniformly stirred powder into a mold according to the corresponding volume density, carrying out compression molding in a mold pressing manner, and carrying out carbonization and graphitization treatment on the demolded material; therefore, the obtained carbon fiber reinforced porous graphite separator has the characteristics of high strength, high through hole rate, uniform pore size distribution and the like.
一种碳纤维增强多孔石墨隔板制备方法，以质量百分比计；使用严格控制好的尺寸在50‑200μm的针状焦、酚醛树脂、造孔剂碳酸氢铵、碳纤维；并将针状焦、酚醛树脂、造孔剂碳酸氢铵、碳纤维按规格称重后放入三维混料机中进行混料搅拌，随后将搅拌均匀的粉料按照相应的体积密度装入模具中，使用模压的方式进行压制成型，对脱模后的材料进行碳化以及石墨化处理；从而得到的碳纤维增强多孔石墨隔板具有强度高、通孔率高、孔径分布均匀等特点。
