New Micro-nano Insulating Brick Series
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.
Micro-nano Insulating Brick Main Advantages and Features
(a) Low thermal conductivity: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.
(b) Low heat capacity:Due to its ultra-light bulk density and low thermal conductivity, the insulating brick accumulates less heat inside, making it more energy efficient.
(c) Good stability:With very low iron oxide and alkali metal content, its stability is better within the specified service temperature.
(d) High strength: Its strength at normal and high temperatures is higher than other products with the same bulk density at the same temperature.
(e) Low size tolerance:The size tolerance is within 0.05mm, the dimensions can be customized according to customer requirements.

New Micro-nano Insulating Brick Typical Applications
It can be used as a thermal insulation backing layer of refractory materials, and the application include: all kinds of industrial furnaces, hot blast furnaces, heating furnaces, smelting furnaces, flue pipes, hot air ducts and other heating and heat generating parts.
(a)Roller kilns Tunnel kiln
Application: Furnace walls and bottom insulation layer of the ceramic roller kiln.
Alternative of following: Lightweight clay brick, high alumina insulating brick, mullite insulating
brick.
Advantages: not easy to shrink, not easy to pulverize, performance not easy to decay, more cost-effective.
(b)Large Hot Air Duct
Application position: Insulation layer of large hot air duct.
Alternative of following: Lightweight clay bricks, high alumina poly-light bricks
Advantages: lower outside wall temperature, more energy efficient, lighter weight of thermal
equipment more cost effective.
The actual measured data when the wall thickness of two different materials is 300mm, the data are compared as follows:
1. With Rongsheng lightweight thermal insulation bricks, the temperature of the outer wall is 70°C (low);
2. With ordinary lightweight heat-insulating bricks, the outside wall temperature is 83°C (high).
The difference of outside wall temperature: 13°C↓.
Conclusion: Rongsheng lightweight thermal insulation bricks reduce the outer wall temperature by 18.57%↓.
The actual measured data, when the temperature of the outside wall reaches 80°C, the data are compared as follows:
1.Using Rongsheng light-weight thermal insulation bricks, only 210mm thick (thin) is needed;
2.Using ordinary light-weight thermal insulation bricks, 330mm thick (thick) is needed.
The difference of wall thickness: 120mm↓.
Conclusion: Rongsheng light-weight thermal insulation bricks reduce the thickness of furnace wall by 57.14%↓
