Was ist ein Kathodenblock?<\/span><\/h2>\n

Der Kathodenblock ist als negative Elektrode bei der Elektrolyse von Aluminium aus Tonerde unerl\u00e4sslich. Er tr\u00e4gt zur Verbesserung der Effizienz der Aluminiumschmelze bei, die viel Strom verbraucht. Er ist also der zentrale Teil der Kathodenstruktur der Aluminium-Elektrolysezelle. <\/span><\/p>\n

Es fungiert also als Kathodenleiter bei der Herstellung von Aluminiumelektrolysen. Es existiert als Auskleidungsmaterial der <\/span>Elektrolyt<\/span><\/a>Schwesterchen<\/a> Zellcontainer. <\/span>Angesichts der weltweit rasant steigenden Nachfrage nach Aluminium spielen Kathodenbl\u00f6cke eine wichtige Rolle in der Industrie.<\/p>\n

Anwendungen<\/h2>\n

Die Hauptfunktion des Kathodenkohleblocks ist die des Auskleidung<\/a> Material der Elektrolysezelle und f\u00fcr die Leitung des elektrischen Stroms.<\/p>\n

Gleichzeitig muss es der Erosion der Hochtemperatur-Kryolithschmelze w\u00e4hrend des Aluminium-Elektrolyseprozesses standhalten.<\/p>\n

Hinzu kommt die elektrochemische Wirkung der Hochtemperaturschlacke im Elektrolyseprozess.<\/p>\n

Seine Qualit\u00e4t spielt daher eine entscheidende Rolle f\u00fcr den Betrieb von Aluminium-Elektrolysezellen.<\/p>\n

Die Sorte wirkt sich direkt auf die Lebensdauer der Elektrolysezelle aus, insbesondere in Bezug auf die Natriumkorrosionsbest\u00e4ndigkeit, die W\u00e4rmeausdehnungsrate und den spezifischen Widerstand.<\/p>\n

Die Verbesserung seiner Qualit\u00e4t verringert den Stromverbrauch in der Produktion und ist von gro\u00dfer Bedeutung f\u00fcr die Verl\u00e4ngerung der Lebensdauer des Elektrolyseurs.<\/p>\n

Die Hauptursache f\u00fcr Sch\u00e4den an einem Aluminium-Elektrolyt Zelle<\/a> ist, dass die Infiltration von Natrium die Ausdehnung des Kohlenstoffblocks verursacht und die Infiltration des geschmolzenen Elektrolyten seinen W\u00e4rmeausdehnungskoeffizienten erh\u00f6ht.<\/p>\n

 <\/p>\n

Merkmale<\/span><\/h2>\n

Es hat einen geringen Widerstand und eine gute Leitf\u00e4higkeit, so dass der Spannungsabfall gering ist, was den Stromverbrauch bei der elektrolytischen Produktion verringern kann. <\/span><\/p>\n

Es hat eine besondere mechanische Festigkeit. W\u00e4hrend <\/span>Aluminium-Elektrolyse<\/span><\/a>wird das Volumen des Kathodenblocks vergr\u00f6\u00dfert, was zu einer erheblichen Ausdehnung f\u00fchrt <\/span><\/p>\n

Spannung und hohe mechanische Festigkeit, was die Schadensquote verringert. <\/span><\/p>\n

Die geringe Porosit\u00e4t des Materials bricht nicht schnell zusammen, wenn der in das Material eindringende Elektrolytgehalt zunimmt. <\/span><\/p>\n

Der Aschegehalt ist gering, so dass er den spezifischen Widerstand nicht erh\u00f6ht und die Leitf\u00e4higkeit nicht beeintr\u00e4chtigt. <\/span><\/p>\n

Der Besch\u00e4digungskoeffizient ist gering, wodurch die Lebensdauer verl\u00e4ngert werden kann.<\/span><\/p>\n
