Preparation method of boron carbide porous skeleton
The invention discloses a preparation method of a boron carbide porous skeleton. The preparation method comprises the following steps: S1, adding aluminum oxide particle powder or aluminum powder into boron carbide powder, adding a high-molecular binder, preparing feed at a relatively high loading capacity, and uniformly mixing in mixing equipment to prepare mixed powder; s2, the mixed powder is placed in a mold, a hydraulic machine is used for direct compression molding in the mold, and a boron carbide briquette is prepared; s3, putting the boron carbide briquette into a vacuum furnace, heating to 500-600 DEG C, removing the high-molecular binder, heating to 1900-1950 DEG C, and forming a sintered porous framework under the pressure of 20-30 MPa. The material mixing main shaft drives the material pushing plate to rotate through the rotating disc, the material pushing plate pushes additives to rotate on the surface of the fixed filter screen frame, the additives can be filtered through the fixed filter screen frame, and impurities carried by the additives can be effectively reduced.
本发明公开了一种碳化硼多孔骨架制备方法，包括以下步骤;S1、在碳化硼粉体中添加氧化铝颗粒末或铝粉，并加入高分子粘结剂，以较高装载量制作喂料，在混料设备中均匀混合，制取混合粉；S2、将混合粉在模具内，利用液压机在模具中直接压制成型，制取碳化硼坯块；S3、将碳化硼坯块置入真空炉中加热至500‑600℃脱除高分子粘结剂，并升温至1900‑1950℃，压力20‑30MPa形成烧结多孔骨架。本发明设置的混料主轴将通过转盘带动推料板转动，推料板将推动添加物在固定滤网架的表面转动，通过固定滤网架可对添加物过滤处理，能够有效的减少添加物携带的杂质。
