Method for improving stability of prebaked anode
The invention discloses a method for improving the stability of a prebaked anode, which is characterized by comprising the following steps of: cleaning the surface of the anode by using acid, alkali and other solutions to remove dirt and oxides on the surface, removing grease and dirt on the surface of the anode by using an organic solvent, corroding the surface of the anode by using a strong acid solution to remove oxides and impurities; a uniform oxide layer is formed on the surface of the anode, and high-temperature roasting needs to be carried out when the prebaked anode is prepared; through the steps of cleaning, degreasing, acid pickling and the like, dirt and impurities on the surface of the anode can be effectively removed, and the smoothness and uniformity of the surface of the anode are guaranteed; an inert gas protective atmosphere is adopted in the oxidation and heating roasting process, so that the surface of the anode can be prevented from being oxidized and polluted; in addition, slow cooling is achieved in the cooling process, cracks and deformation on the surface of the anode can be avoided, and the stability of the anode is guaranteed; therefore, all the steps in the method are key steps for preparing the high-quality prebaked anode, and the stability of the prebaked anode can be improved.
本发明公开了一种提高预焙阳极稳定性的方法，其技术方案要点是：使用酸、碱等溶液清洗阳极表面，去除表面污物和氧化物，使用有机溶剂去除阳极表面的油脂和污垢，使用强酸溶液腐蚀阳极表面，去除氧化物和杂质，在高温下，使阳极表面形成一层均匀的氧化层，在制备预焙阳极时，需要进行高温焙烧；通过清洗、脱脂和酸洗等步骤，可以有效地去除阳极表面的污垢和杂质，保证阳极表面的光洁度和均匀性；在氧化和加热焙烧过程中采用惰性气体保护气氛，可以避免阳极表面受到氧化和污染；此外，在冷却过程中缓慢冷却，可以避免阳极表面出现裂纹和变形，保证阳极的稳定性；因此，本发明中的步骤都是制备高质量预焙阳极的关键步骤，可以提高预焙阳极的稳定性。
