Product Advantages

Key Features for Insulating Firebrick

•Low thermal conductive , low heat storage

•Purity

•Good thermal insulation , enable the use of thin-walled constructions

•The good alumina contents confer good refractoriness

•Low iron and alkali fluxcontent contributes to their stability to reducing atmosphere

•These can be machined to special shapes , incurring fewer sections and joints

Insulating Firebrick are classified to Clay Insulating Brick,High Alumina Insulating Brick and Mullite Insulating Brick.

Features of Mullite Insulation Bricks：

1. Excellent thermal insulation performance: Mullite thermal insulation bricks have low thermal conductivity, excellent thermal insulation effect and durability. In a high temperature environment, it can effectively reduce the loss of heat energy and avoid waste of heat energy.

2. Excellent fire resistance: Mullite is a natural inorganic non-metallic material, which can maintain stable physical and chemical properties at high temperatures, is not easy to melt and deform, and has strong fire resistance.

3. Stable chemical properties: Except for strong corrosive media such as dilute acid and hydrofluoric acid, mullite is basically not corroded and damaged by general chemical substances, and has good chemical property stability.

Products Applications

Use of mullite insulation bricks:

1. High-temperature industrial field: Mullite insulation bricks are widely used in high-temperature industrial fields such as iron and steel smelting, electric power, glass, ceramics, cement, and petrochemical industry. In these fields, mullite insulation bricks can be used as lining materials for various kilns, high-temperature reaction kettles, heat treatment furnaces, etc., to improve the working efficiency and service life of these industrial equipment.

2. Construction field: Mullite insulation bricks can also be used in the field of building thermal insulation. For example, in the fields of thermal insulation materials such as thin-layer external wall insulation and roof insulation, the excellent thermal insulation performance and durability of mullite insulation bricks can provide people with efficient building insulation materials.
