Wat is kathodeblok?<\/span><\/h2>\n

Het kathodeblok is essentieel als negatieve elektroden in het elektrolyseproces van aluminium uit aluminiumoxide. Het helpt de effici\u00ebntie van het smelten van aluminium, dat veel elektriciteit verbruikt, te verbeteren. Het is dus het centrale deel van de kathodestructuur van de aluminium elektrolytische cel. <\/span><\/p>\n

Het fungeert dus als een kathodegeleider in het productieproces van aluminiumelektrolyse. Het bestaat als het voeringsmateriaal van de <\/span>elektrolytisch<\/span><\/a>zus<\/a> celcontainer. <\/span>Met de wereldwijd snel stijgende vraag naar aluminium spelen kathodeblokken een essenti\u00eble rol in de industrie.<\/p>\n

Toepassingen<\/h2>\n

De primaire functie van het kathodekoolstofblok is als de voering<\/a> materiaal van de elektrolysecel en voor de geleiding van elektrische stroom.<\/p>\n

Tegelijkertijd moet het bestand zijn tegen de erosie van kryolietsmelt op hoge temperatuur tijdens het aluminiumelektrolyseproces.<\/p>\n

Er is ook de elektrochemische werking van slak van hoge temperatuur in het elektrolyseproces.<\/p>\n

Daarom speelt de kwaliteit ervan een essenti\u00eble rol in de werking van aluminium elektrolytische cellen.<\/p>\n

De kwaliteit heeft een directe invloed op de levensduur van de elektrolytische cel, vooral wat betreft weerstand tegen natriumcorrosie, thermische uitzettingssnelheid en weerstand.<\/p>\n

Het verbeteren van de kwaliteit verlaagt het energieverbruik tijdens de productie en is van groot belang voor het verlengen van de levensduur van de elektrolytische cel.<\/p>\n

De belangrijkste oorzaak van schade aan het van een aluminium elektrolytische cel<\/a> is dat de infiltratie van natrium de uitzetting van het koolstofblok veroorzaakt en de infiltratie van de gesmolten elektrolyt de thermische uitzettingsco\u00ebffici\u00ebnt verhoogt.<\/p>\n

 <\/p>\n

Kenmerken<\/span><\/h2>\n

Het heeft een lage weerstand en een goed geleidingsvermogen, dus de spanningsval is klein, wat het stroomverbruik van elektrolytische productie kan verminderen. <\/span><\/p>\n

Het heeft een specifieke mechanische sterkte. Tijdens <\/span>aluminium elektrolyse<\/span><\/a>zet het volume van het kathodeblok uit, wat resulteert in een aanzienlijke expansie <\/span><\/p>\n

spanning en hoge mechanische sterkte, waardoor de schade beperkt wordt. <\/span><\/p>\n

De lage porositeit breekt niet snel af wanneer de hoeveelheid elektrolyt die erin doordringt toeneemt. <\/span><\/p>\n

Het asgehalte is klein, zodat het de specifieke weerstand niet verhoogt en het geleidingsvermogen niet be\u00efnvloedt. <\/span><\/p>\n

De schadeco\u00ebffici\u00ebnt is klein, wat de levensduur kan verlengen.<\/span><\/p>\n

Kathodeblokken worden gebruikt voor de metselwerkbekleding van aluminium elektrolytische cellen. Als een positieve elektrode geleidend koolstofmateriaal, heeft het de kenmerken van weerstand tegen hoge temperaturen, weerstand tegen gesmolten zoutcorrosie en goede geleidbaarheid. Er zijn vele soorten, waaronder gewoon koolstofkathodeblok, semi-grafiet koolstofblok, hooggrafiet koolstofblok en grafietkathodeblok.
