DZNS Refractory Chem 1600

Ultra-high temperature refractory concrete for aggressive environments. DZNS Refractory Chem 1600 is an ultra-high temperature refractory concrete in the form of a dry packaged mixture, designed for use in extremely aggressive chemical environments at temperatures up to 1600 °C. The material is designed for use in conditions combining high temperatures, acid-alkaline aggression, chemically active gases, corrosive condensate and continuous production cycles, where standard refractory materials cannot withstand the loads.

Temperature resistance:

• Maximum operating temperature: up to 1600 °C
• Recommended operating temperature: up to 1500 °C

Scope of application (aggressive environments):

Used for:

• Lining of high-temperature chemical reactors;
• Boilers and thermal units with aggressive environments;
• Gas ducts and chimneys with chemically active emissions
• Combustion chambers and thermal zones;
• Industrial installations in the chemical, energy and processing industries;
• Continuous-operation thermal units.

Features of aggressive environments

The material is specially adapted to:

• The effects of strong acidic and alkaline environments;
• The action of chemically active gases;
• Corrosion-active condensate;
• Intensive thermal cycles;
• Increased humidity and steam;
• Prolonged continuous operation modes.

Key advantages:

• Extremely high chemical resistance
• Thermal resistance up to 1600 °C
• Stable operation in extremely aggressive environments
• Exceptional resistance to thermal shock
• Minimal shrinkage even at high temperatures
• Long-term operation in the most severe conditions

Technical features

• Material type: dry concrete mix;
• Structure: dense, chemically and thermally stable;
• Binder: special ultra-high-temperature mineral, resistant to acids and alkalis;
• Filler: high-purity refractory mineral filler of a special grade;
• Heating behaviour: stable without degradation at temperatures up to 1600 °C.

Recommendations for use

1. Mix with clean water until a homogeneous plastic mass is obtained;
2. Apply to a thoroughly cleaned and prepared surface;
3. Avoid rapid drying after application;
4. Perform the first heating in stages and in a controlled manner, with a gradual increase in temperature.
