Modification method of carbon anode for fluorine preparation
The invention belongs to the field of fluorine preparation anode materials, and particularly relates to a method for modifying a carbon anode for fluorine preparation, which comprises the following steps of: (1) preheating and vacuumizing a prefabricated carbon plate by adopting a vacuum pressure impregnation tank; (2) carrying out pressure dipping treatment on the prefabricated carbon plate by adopting epoxy resin; and (3) putting the carbon plate subjected to the epoxy resin dipping treatment into a pit type resistance furnace for high-temperature roasting, so as to obtain the fluorocarbon anode. The method only needs one-time resin impregnation and one-time high-temperature roasting for preparation, raw materials are cheap and easy to obtain, and equipment operation is simple; the modified fluorine-making carbon plate has the advantages of high bulk density, low porosity, high current density, high mechanical strength, long service cycle and the like, and is suitable for large-scale use of a medium-temperature electrolysis fluorine-making process.
本发明属于制氟阳极材料领域，具体涉及一种制氟用碳阳极的改性方法，该方法包括：步骤(1)、采用真空压力浸渍罐对预制碳板进行预热、抽空处理；步骤(2)、采用环氧树脂对预制碳板进行加压浸渍处理；步骤(3)、将环氧树脂浸渍处理后的碳板放入井式电阻炉中进行高温焙烧，即得到制氟碳阳极。本发明方法仅需一次树脂浸渍、一次高温焙烧即可制得，原料便宜易得，设备操作简单；改性处理后的制氟碳板具有体密度大、气孔率低、电流密度大、机械强度高、使用周期长等优点，适合中温电解制氟工艺规模化使用。
