Product Description
Product Description:
Floating bead brick is a heat-insulating refractory product made of floating bead as the main raw material.Floating beads are hollow aluminum silicate glass beads floated from fly ash from thermal power plants.It has light body, thin wall, hollow, smooth surface, high temperature resistance and good heat insulation performance.Utilizing these excellent properties of floating beads, a lightweight heat-insulating refractory material with excellent heat preservation performance can be manufactured.The production of floating bead bricks can be formed by a semi-dry method.
Product Features:
Low thermal conductivity, high strength, firmness and durability, simple construction, lightweight and easy to load and unload, economical, environmentally friendly, sound insulation, fire prevention and other functions.
typical application:
There are thermal boilers, glass furnaces, cement furnaces, fertilizer gas furnaces, blast furnaces, thermal furnaces, coking furnaces, electric furnaces, casting and casting bricks, etc.
The physical and chemical indicators are as follows:
Refractoriness≥1580℃
Compressive strength at room temperature≥10MPa
Thermal conductivity (350±25℃)≤0.5W/(m·K)
Reburning line changes (1250℃×2h) ≤2%
