Manufacturing process and application of cold isostatic pressing graphite
The invention relates to a manufacturing process and application of cold isostatic pressing graphite. The manufacturing process comprises the following steps: S1, providing pitch coke and petroleum coke, and providing modified pitch; S2, activating to obtain activated pitch coke and activated petroleum coke; S3, obtaining a mixed raw material; S4, obtaining a mixed material; S5, performing rolling treatment on the mixed material to obtain a thin sheet, and grinding the thin sheet to obtain powder; S6, performing cold isostatic pressing forming treatment on the powder, to obtain a parison; and S7, performing roasting-dipping treatment, to obtain a roasted blank. The roasting treatment is performed by heating and cooling based on a 744-hour roasting temperature curve. The impregnation treatment is performed in a composite impregnation liquid, and the composite impregnation liquid comprises medium-temperature coal tar pitch and furan resin. According to the manufacturing process, the production efficiency is high, the manufacturing cost is low, high-purity, high-weather-resistance and high-quality graphite can be manufactured, and the service life is long when the manufactured graphite is applied to a polycrystalline silicon bottom plate.
本发明涉及一种冷等静压石墨的制作工艺及其应用。上述制作工艺包括如下步骤：S1提供沥青焦、石油焦，提供改制沥青；S2活化处理得到活化沥青焦、活化石油焦；S3得到混合原料；S4得到混配料；S5所述混配料经轧制处理变成薄片，对所述薄片进行研磨，得到粉末；S6对所述粉末进行冷等静压成型处理，得到型坯；S7焙烧‑浸渍处理，制得焙烧料坯。焙烧处理基于744小时焙烧温度曲线进行升温降温。所述浸渍处理在复合浸渍液中进行，其中，所述复合浸渍液包括中温煤沥青和呋喃树脂。本发明的制作工艺，生产效率高、制作成本低，可制作得到高纯度、高耐候性以及高质量的石墨，并且制得的石墨应用在多晶硅底板中时，使用寿命长。
