Mattone isolante di diatomite all'ingrosso

Diatomite insulation brick is often used as insulation for high-temperature kilns and other thermal equipment. Diatomite bricks comprise a small amount of binder and combustible materials added to diatomite. The production of diatomite bricks requires wetting, mixing Raw materials, modanatura, firing, and other steps.

The main chemical composition of diatomite insulation firebrick

Diatomite insulation brick’s main chemical composition is SiO₂, followed by Al₂O₃, and impurities such as iron oxides, potassium, sodium, calcium, and magnesium.

Advantages of diatomite bricks

1. The fire-resistant thermal expansion rate is small, and not easy to deform.
2. It has lightweight and high compressive strength.
3. Good heat preservation effect, and reduces energy consumption.
4. Low bulk density and small thermal conductivity.
5. The construction is convenient and the surface is smooth.

Application of diatomite insulation bricks

Diatomite insulation bricks are often used in electric power, metallurgia, industria chimica, and cement industries, especially in pipes and fireplaces of thermal equipment.
