\u00bfQu\u00e9 es el bloque cat\u00f3dico?<\/span><\/h2>\n

El bloque cat\u00f3dico es esencial como electrodo negativo en el proceso de electr\u00f3lisis del aluminio a partir de la al\u00famina. Ayuda a mejorar la eficiencia de la fundici\u00f3n de aluminio, que consume mucha electricidad. Por lo tanto, es la parte central de la estructura cat\u00f3dica de la celda electrol\u00edtica de aluminio. <\/span><\/p>\n

As\u00ed pues, act\u00faa como conductor cat\u00f3dico en el proceso de producci\u00f3n por electr\u00f3lisis del aluminio. Existe como el material de revestimiento de la <\/span>electrol\u00edtico<\/span><\/a>hermana<\/a> contenedor de c\u00e9lulas. <\/span>Con el r\u00e1pido aumento de la demanda de aluminio en todo el mundo, los bloques cat\u00f3dicos desempe\u00f1an un papel esencial en la industria.<\/p>\n

Aplicaciones<\/h2>\n

La funci\u00f3n principal del bloque de carb\u00f3n cat\u00f3dico es la de forro<\/a> material de la c\u00e9lula de electr\u00f3lisis y para la conducci\u00f3n de la corriente el\u00e9ctrica.<\/p>\n

Al mismo tiempo, debe soportar la erosi\u00f3n de la criolita fundida a alta temperatura durante el proceso de electr\u00f3lisis del aluminio.<\/p>\n

Tambi\u00e9n existe la acci\u00f3n electroqu\u00edmica de la escoria de alta temperatura en el proceso de electr\u00f3lisis.<\/p>\n

Por lo tanto, su calidad desempe\u00f1a un papel vital en el funcionamiento de las c\u00e9lulas electrol\u00edticas de aluminio.<\/p>\n

El grado afecta directamente a la vida \u00fatil de la c\u00e9lula electrol\u00edtica, especialmente en t\u00e9rminos de resistencia a la corrosi\u00f3n del sodio, \u00edndice de expansi\u00f3n t\u00e9rmica y resistividad.<\/p>\n

La mejora de su calidad reduce el consumo de energ\u00eda en la producci\u00f3n y es de gran importancia para prolongar la vida \u00fatil del electrolizador.<\/p>\n

La principal causa de da\u00f1o a la misma de un electrol\u00edtico de aluminio c\u00e9lula<\/a> es que la infiltraci\u00f3n de sodio provoca la dilataci\u00f3n del bloque de carbono, y la infiltraci\u00f3n del electrolito fundido aumenta su coeficiente de dilataci\u00f3n t\u00e9rmica.<\/p>\n

 <\/p>\n

\"Bloques\u00a0\"Bloque<\/p>\n

 <\/p>\n

Caracter\u00edsticas<\/span><\/h2>\n

Tiene baja resistencia y buena conductividad, por lo que su ca\u00edda de tensi\u00f3n es peque\u00f1a, lo que puede reducir el consumo de energ\u00eda de la producci\u00f3n electrol\u00edtica. <\/span><\/p>\n

Tiene una resistencia mec\u00e1nica espec\u00edfica. Durante <\/span>electr\u00f3lisis del aluminio<\/span><\/a>el volumen del bloque cat\u00f3dico se expande, lo que provoca una expansi\u00f3n considerable <\/span><\/p>\n

tensi\u00f3n y alta resistencia mec\u00e1nica, lo que reducir\u00e1 el \u00edndice de da\u00f1os. <\/span><\/p>\n

Su baja porosidad no se rompe r\u00e1pidamente cuando aumenta el contenido de electrolito que penetra en \u00e9l. <\/span><\/p>\n

El contenido de ceniza es peque\u00f1o, por lo que no aumentar\u00e1 la resistencia espec\u00edfica ni afectar\u00e1 a la conductividad. <\/span><\/p>\n

Su coeficiente de da\u00f1o es peque\u00f1o, lo que puede prolongar su vida \u00fatil.<\/span><\/p>\n
