Hot-pressed graphite polar plate and preparation method thereof, alkaline electrolytic bath and water electrolysis hydrogen production equipment
The invention discloses a hot-pressed graphite polar plate and a preparation method thereof, an alkaline electrolytic bath and water electrolysis hydrogen production equipment, the hot-pressed graphite polar plate comprises a main polar plate and a polar frame, the polar frame surrounds the peripheral side of the main polar plate, and the polar frame and the main polar plate are of an integrally formed structure; wherein the main polar plate comprises graphite powder, alkali-resistant resin, a conductive agent and carbon fibers according to a first preset proportion; the pole frame comprises graphite powder and alkali-resistant resin in a second preset proportion; the content of the alkali-resistant resin in the second preset proportion is greater than the content of the alkali-resistant resin in the first preset proportion. A certain amount of conductive agent and carbon fiber are added into the main polar plate, and carbon black can be selected as the conductive agent, so that the conductivity and the electrical property of the main polar plate can be improved; the content of alkali-resistant resin in the pole frame is greater than that of alkali-resistant resin in the main pole plate, so that the resin content of the pole frame is more than that of the main pole plate, the strength and the corrosion resistance of the pole frame are further enhanced, and the overall performance of the electrolytic cell can be effectively improved.
本发明公开了一种热压石墨极板及制备方法、碱性电解槽和电解水制氢设备，所述热压石墨极板包括主极板和极框，极框围绕所述主极板的周侧，且所述极框和所述主极板为一体成型结构；其中，主极板包括第一预设比例的石墨粉、耐碱性树脂、导电剂和碳纤维；极框包括第二预设比例的石墨粉和耐碱性树脂；第二预设比例中的耐碱性树脂含量大于第一预设比例中的耐碱性树脂含量。主极板中添加一定量的导电剂和碳纤维，导电剂可选用碳黑，这样可提高主极板的电导率及电学性能；由于极框中耐碱性树脂含量大于主极板中的耐碱性树脂含量，因此相对于主极板，极框的树脂含量更多，使极框的强度和耐腐蚀性进一步增强，可有效提高电解槽的整体性能。
