High-purity isostatic pressing graphite material for spectral analysis and preparation method of high-purity isostatic pressing graphite material
The invention relates to a preparation method of a high-purity isostatic pressing graphite material for spectral analysis. The preparation method comprises the following steps: obtaining components meeting index conditions, preparing secondary carbon black, carrying out primary dry mixing, carrying out secondary dry mixing, carrying out wet mixing, carrying out isostatic compaction and subsequent process treatment, and carrying out graphitization treatment to prepare the high-purity isostatic pressing graphite material for spectral analysis. By fusing with other materials in the raw materials, the mechanical strength of the finished graphite material can be supplemented; according to the preparation method, the raw materials are ground, then are subjected to compression molding and sintering carbonization treatment, and finally are subjected to a graphitization process, so that the density and the strength of the high-purity graphite material can be increased.
本发明涉及一种光谱分析用高纯等静压石墨材料的制备方法，包括以下步骤：获取满足指标条件的各组分‑二次炭黑的制备‑第一次干混‑第二次干混‑湿混‑等静压成型及后续工艺处理‑石墨化处理制成光谱分析用高纯等静压石墨材料，本发明通过在原料沥青焦中加入二次炭黑、石墨粉等，与原料中的其他材料相融合，可以补充成品石墨材料的机械强度；本发明对原料进行研磨，再通过模压成型、烧结炭化处理，最后通过石墨化工艺，可以增加高纯石墨材料的密度和强度。
