What are the common sizes of aluminum silicate ceramic fiber blanket for electrolytic cell insulation material?

What are the common sizes of aluminum silicate ceramic fiber blanket for electrolytic cell insulation material? There are several commonly used “standard sizes” of aluminum silicate ceramic fiber blankets for electrolytic cell insulation to meet the needs of different parts. Most manufacturers can customize according to the groove type, and commonly used blankets with thicknesses of 20mm, 30mm, and 50mm are used in different areas to balance insulation effect and construction convenience.

The key insulation materials for electrolytic cells include 1260 ℃ ordinary aluminum silicate blanket, 1400 ℃ high aluminum blanket, and 1430 ℃ zirconium containing blanket. The core requirements are high temperature resistance, low thermal conductivity, alkali resistance, no slag shedding, and resistance to aluminum liquid flue gas corrosion.

Ceramic fiber blanket standard commonly used sizes (rolled blanket)

1. Width (most commonly used)
610mm (mainstream, most commonly used for electrolytic cell construction)
1220mm (large surface laying, less used)
2. Length
7200mm (7.2m/roll, industry standard)
6000mm, 8000mm can also be customized
3. Thickness (required for electrolytic cells)
10mm、20mm、30mm、40mm、50mm
Insulation for the side and bottom of the electrolytic cell: 30mm, 40mm, 50mm are most commonly used

When selecting ceramic fiber blankets for electrolytic cells, in addition to paying attention to size, it is also important to confirm the following two parameters:

1. Temperature resistance level: Aluminum silicate fiber blanket is divided into ordinary type (temperature resistance of about 1000 ℃), standard type (1050 ℃), high-purity type (1100 ℃), high aluminum type (1200 ℃), and zirconium containing type (above 1350 ℃). Please choose the appropriate model based on the actual operating temperature of the electrolytic cell.
2. Bulk density: The conventional bulk density is generally between 96kg/m ³ and 128kg/m ³. The higher the bulk density, the better the compression resilience and overall insulation performance of the blanket.
