Ultra High Strength Nano Insulation Block
Ultra High Strength Nano Insulation Block/High strength/Low thermal conductivity
Summary:
The temperature of the cold side of large rotary kilns in the cement industry is generally 280-320℃. Since there is no material with both high strength and low thermal conductivity, it cannot be effectively insulated, resulting in a huge waste of energy. According to the calculation, using 40-50mm thick ultra-high strength nano insulation block with conventional cement kiln working layer material can reduce the cold surface temperature of the kiln body by 100℃-130℃. A medium-sized clinker production line with a daily production capacity of 5.000 tons can save about 5,500 tons of standard coal per year. It can save 20 billion yuan of fuel cost every year in the cement rotary kiln. Not to mention, various types of rotary kilns are applied in dozens of industries, which can save hundreds of billions for enterpises every year.

Range of application:
This series of products combines the compressive strength of heavy bricks with a density of over 2.3g/cm3, while also possessing the thermal conductivity of lightweight bricks with a density of 0.8g/cm3. It is the best choice for insulation materials with high requirements for compressive strength on dynamic kilns such as cement rotary kilns, hazardous waste rotary kilns, alumina calcination rotary kilns, and pellet rotary kilns.
Packaging and Storage:
Wooden pallets+thermoplastic film packaging, The packaging size and weight vary depending on the variety;Store in a dry, ventilated, moisture-proof, and sun protected warehouse. Storage period is 24 months.
