Introduction to different densities of ceramic fiber board insulation materials for electrolytic cells? Ceramic fiber board has become a key backing insulation material in the insulation system of electrolytic cells, especially aluminum electrolytic cells, due to its excellent thermal insulation performance and structural stability. Its density is the core indicator that determines the insulation effect, mechanical strength, and applicable parts. Typically, the density of ceramic fiberboard ranges widely from 200 kg/m ³ to over 900 kg/m ³ to meet the operational requirements of different areas such as the bottom, sides, and end walls of the electrolytic cell.
Ceramic fiber board is the preferred choice for hard fire-resistant insulation of the side walls, bottom of the electrolytic cell, cathode steel rod, furnace mouth, flue and other parts. Different densities directly affect high temperature resistance, compression resistance, powdering resistance, and insulation effect. The following will explain them one by one according to the commonly used densities of electrolytic cells.
Suggestions for selecting different densities of ceramic fiberboard:
Aluminum electrolytic cell scenario: Priority should be given to ceramic fiber boards with a capacity of 260-320kg/m ³ or 350-400kg/m ³. Low density board meets the basic insulation needs and has a lower cost; Medium density board performs better in areas with high temperature or mechanical stress, such as side walls.
High temperature industrial scenario: If the temperature exceeds 1400 ℃, special formula ceramic fiberboard containing zirconium or other materials should be selected, with a density usually between 350-400kg/m ³.
Economic considerations: The higher the density, the higher the material cost and construction difficulty, and it is necessary to balance performance and cost according to specific working conditions.
