Classification of Insulation Bricks
Insulation bricks can be classified into three major categories based on their material, application, and performance. Common types include lightweight clay bricks, high-alumina lightweight aggregate bricks, and mullite lightweight insulation bricks, etc. Different types have significantly different application scenarios.
Henan Lite is a comprehensive industrial base for refractory materials in China. Thecompany has four major product series production bases: refractory bricks, unshapedrefractory materials, fiber products, and kiln furniture. its products are widely used invarious industries such as steel metallurgy, glass, ceramics, and petrochemicals
Classification of Insulation Bricks by Materials and Processes
The core classification basis of insulation bricks is the raw materials and production processes. The main types and characteristics are as follows:
A.Type Primary B.Raw Materials C.Key Performance D.Typical Application Scenarios
1.Lightweight Clay Brick ,Clay ,Aluminum content 30%-46%, fire resistance temperature 800-1200℃ Industrial kiln furnace insulation layer, thermal power boiler
2.High-Aluminum Lightweight Aggregate Brick ,High-alumina bauxite ,Aluminum content ≥ 48%, fire resistance temperature 1350℃ Glass kiln furnace, steel heat treatment furnace
3.Mullite Lightweight Insulation Brick ,Mullite High strength, low thermal conductivity (0.15-0.35W/(m·K)) Petrochemical industrial furnaces, ceramic kiln trucks
4.Siltstone Insulation Brick, Siltstone Light weight, good insulation, but highly hygroscopic Wall insulation layer, low-temperature heat insulation environment
5.Expanded Perlite Insulation Brick, Expanded perlite ,A1 grade fireproof, waterproof, moisture-proof, thermal conductivity 0.07W/m·K Building partition wall, boiler lining, cold storage
6.Sintered Insulation Brick, Clay, shale, fly ash, etc. Density grade 700-1000kg/m³, strength MU3.5-MU15 Building enclosure structure.
Recommendations for Selecting Insulation Bricks
Industrial kilns: Prefer mullite lightweight bricks and high-alumina lightweight bricks, considering both high-temperature resistance and heat insulation properties .
Building partitions: Perlite insulation bricks or fired insulation bricks, which are fireproof, moisture-proof, and easy to install .
Low-temperature insulation: Silica fume insulation bricks have low costs, but attention should be paid to moisture-proofing treatment
