What are the types of insulation materials for electrolytic cells?

What are the types of insulation materials for electrolytic cells? The lining of the aluminum electrolytic cell adopts a layered composite insulation system, which is divided into six categories according to its shape: fiber flexible insulation, hard insulation bricks/boards, powder bulk materials, nano ultra-low thermal conductivity insulation, amorphous casting anti-seepage insulation, and special composite insulation. It is suitable for different temperature ranges (300-1350 ℃) of the bottom, sides, ends, and shell backing of the cell. There are different types of insulation materials for electrolytic cells, and Rosewool Insulation Refractory Co.,Ltd. have everything they need. Moreover, different levels and grades can provide solutions according to customers' usage temperature and application needs;

What are the types of insulation materials for electrolytic cells?

1. Ceramic fiber series

The core material is aluminum silicate fiber, classified into temperature resistance levels, with multiple forms of blankets/boards/modules, and flexible bonding with irregular structures; There are ordinary aluminum silicate fibers, high alumina ceramic fibers, zirconium containing ceramic fibers, ceramic fiber modules, etc;

2. Hard shaped insulation board/insulation brick (main insulation layer at the bottom of the groove, mainstream in the industry)

Hard silica calcium stone insulation board, vermiculite insulation board, magnesia stone insulation brick

3. Nano microporous/aerogel insulation board (high-end energy-saving ultra-low heat conduction layer)

Nano microporous insulation board, aerogel felt composite insulation board

4. Amorphous insulation casting material/anti-seepage material (composite anti-seepage and insulation integrated)

The anti-seepage pouring material and insulation refractory mortar on the side of the electrolytic cell, as well as the transition isolation between carbon bricks and insulation layer, block the penetration of electrolytes and sodium vapor.
