DZNS Refractory Chem 1200

Refractory concrete for aggressive environments. DZNS Refractory Chem 1200 is a specialised refractory concrete in the form of a dry packaged mixture, designed for use in chemically aggressive environments with operating temperatures up to 1200 °C. The material is designed for stable operation when exposed to acidic and gaseous environments, chemically active vapours, condensate and temperature fluctuations, where standard refractory concretes quickly degrade.

Temperature resistance:

• Maximum operating temperature: up to 1200 °C
• Recommended operating temperature: up to 1100 °C

Scope of application (aggressive environments)

Used for:

• Lining of boilers and thermal units;
• Gas ducts and chimneys;
• Combustion chambers;
• Installations with acidic and gaseous environments;
• Chemical and industrial installations;
• Periodic thermal units.

Features of aggressive environments:

The material is specially adapted to:

• The effects of acidic gases and vapours;
• The effects of chemically active condensate;
• Increased humidity;
• Temperature fluctuations;
• Corrosion-active operating conditions.

Main advantages

• Increased chemical resistance
• Stable operation in aggressive gas environments
• Thermal stability up to 1200 °C
• Resistance to temperature cycles
• Minimal shrinkage after heating
• Long-term operation in corrosive conditions

Technical features

• Material type: dry concrete mix;
• Structure: dense, chemically resistant;
• Binder: special mineral, resistant to acidic environments;
• Filler: refractory mineral filler;
• Behaviour when heated: stable, without loss of strength or crumbling.

Packaging

• Bag — 25 kg
• BigBag — 1000 kg (with polypropylene liner for moisture protection)
