Aerogel Material Apply in Kiln& Furnace

Refractory insulation materials for industrial furnaces are a class of materials that are resistant to high temperatures, have low thermal conductivity, are resistant to thermal shock, are flame retardant, and can slow down the heat loss caused by heat conduction and heat convection.

In recent years, the industry has conducted a lot of in-depth research on refractory insulation materials and successfully developed many types of materials such as glass wool, mineral wool, microporous calcium silicate, composite silicate, closed-cell expanded perlite, ceramic fiber and so on. However, the disorderly exploitation and improper use of refractory raw materials have led to serious waste of resources, serious environmental pollution, high energy consumption, overcapacity of primary products and low proportion of high value-added products.

Therefore, "green and high performance" refractory insulation materials can meet the requirements of national sustainable development strategy and energy saving and emission reduction policy. Besides, most of the refractory insulation materials are loose and porous, and the voids in the materials account for a large proportion, so the materials will absorb a lot of water when they are in contact with water, and the thermal conductivity of water is much larger than that of air, which will seriously affect the thermal insulation performance of the materials.

Traditional insulation materials in Kiln & Furnace have such weakness,

• High thermal conductivity, thick insulation layer, and unsatisfactory insulation effect.
• Mostly hard material, loose and porous, difficult to accumulate dense, convection heat dissipation is very obvious.
• Easy to crisp and crack in long-term use, resulting in poor insulation effect.
• Infrared diffuse reflection is serious, resulting in furnace heat storage, high lining temperature, easy to be oxidation corrosion.

Compared to mentioned above, Sino-Aerogel Insulation Materials have such advantages, 

• Low thermal conductivity, high temperature resistance, adiabatic and flame retardant, can significantly reduce the heat loss of industrial furnaces.
• Effectively reduce the thickness of the insulation layer, saving space and construction costs.
• Tensile and compressive resistance, dense material structure, which can effectively reduce air convection heat dissipation.
• Safe and environmentally friendly.
• Good infrared reflection effect is conducive to improving the heat exchange in the furnace, improving the temperature uniformity in the furnace chamber and reducing the temperature of the furnace lining.
