Carbon anode plate for electrolytic fluorine preparation and preparation method thereof
The invention relates to the technical field of carbon anode plates, and particularly discloses a carbon anode plate for electrolytic fluorine production and a preparation method thereof, and the preparation method comprises the following steps: immersing a thermosetting impregnant containing metal salt into pores and the surface of the carbon anode plate; and carbonizing the metal salt and the thermosetting impregnant in the pores and on the surface of the carbon anode plate through roasting to form the metal oxide-containing carbon anode plate for electrolytic fluorine production. According to the method, after the carbon anode plate is dried, metal nitrate or sulfate and a thermosetting impregnant are embedded into the carbon anode plate, so that F on the surface of the carbon anode and graphite form nearly ionic bond combination in the electrolysis process, the surface is still kept flat after treatment, and the anode effect of the carbon anode plate can be effectively retarded when the electrolytic cell works.
本发明涉及碳阳极板技术领域，具体公开了一种电解制氟用碳阳极板及其制备方法，该制备方法包括如下步骤：通过将含有金属盐的热固型浸渍剂浸入碳阳极板孔道及表面；通过焙烧使碳阳极板的孔道内及表面上的金属盐和热固型浸渍剂碳化，以形成含有金属氧化物的电解制氟用碳阳极板。本发明先将碳阳极板烘干后利用金属的硝酸盐或硫酸盐以及热固型浸渍剂，嵌入碳阳极板使电解过程中碳阳极表面的F与石墨形成近于离子键结合，并且经过处理后表面仍保持平整，可以有效地阻滞碳阳极板在电解槽工作时的阳极效应。
