Alkali (acid) series refractory castable Features: 1, using high alkaline siliceous aggregates, high temperature aluminum-silicon components lined with a base layer to generate high-viscosity liquid to prevent air base erosion, and enhance resistance lining basic energy; 2, has some anti-skinning properties. Use parts: pre-heater system, cooler cooling section physical and chemical properties: Name of special high-strength alkali-resistant refractory castable refractory castable acid and alkali (provincial new products) high-temperature alkaline refractory castable grades JS-13NL JS- T130 JS-14N maximum use temperature (℃) 1300 1350 1400 volume density (kg / m3) 110 ℃ × 24h≥ 2100 2200 2200 Chemical Composition (%) Al2O3≤ 48 48 ≥45 SiO2≥ 50 45 / cold compressive strength ( MPa) 110 ℃ × 24h≥ 70 80 80 1100 110 ℃ × 24h≥ 7 8 8 1100 ℃ × 3h≥ 7 8 8 firing line after the rate change ℃ × 3h≥ 70 80 80 Cold flexural strength (MPa) (%) 1100 ℃ × 3h≥ -0.5 -0.3 ± 0.4 Thermal conductivity (W / (mk)) 350 ℃ ≤ 0.87 0.90 0.90 alkali resistance JC / T808-1987 a one two Acid Test (%) HG / T3210 -2002≥ / 94 / Construction of reference water (%) 6.5 7.5 6-7 6-7 1-3 Construction of vibration using the site level using a dry process kiln with preheater incineration function, use the same site - 13NL and flue, chimney lining the lower and so the overall work. Upgrading of product characteristics JS-13NL of 1. -13NL: anti-alkali crack, high strength, energy and good integrity. 2. T130 also acid and alkali, using the results compared -13NL better and live longer. 3. According to user requirements can add heat-resistant steel fiber 4. Refer to the construction process.
