Brief Description
The new micro-nano insulating brick series products solve the needs of thermal insulation of the wall and bottom of various large furnaces, and the working temperature can be from 600°C to 1400°C. With a wide range of application, good thermal insulation performance and high strength, the product can meet the requirements of energy saving and environmental protection of various furnaces.
Advantages
With low thermal conductivity, it has good heat insulation effect and can make the furnace wall thickness thinner under the same temperature condition, thus saving more cost.
Due to its ultra-light bulk density and low thermal conductivity, the insulating brick accumulates less heat inside, making it more energy efficient.
With very low iron oxide and alkali metal content, its stability is better within the specified service temperature.
Its strength at normal and high temperatures is higher than other products with the same bulk density at the same temperature.
The size tolerance is within 0.05mm, the dimensions can be customized according to customer requirements.
