The new Micro-nano Insulation Bricks products can solve the need for thermal insulation of the wall and bottom of various large furnaces, and the working temperature can be from 600℃ to 1400℃. With a wide range of applications, good thermal insulation performance, and high strength, the product can meet the requirements of energy saving and environmental protection for various industrial furnaces.
Main Performance Advantages and Features of Micro-nano Insulation Bricks
(a) Low thermal conductivity: With low thermal conductivity, it has a 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, and the dimensions can be customized according to customer requirements.
Indicators New High-Temperature Micro-nano Insulation Bricks can achieve
High-Temperature Micro-nano Insulation Bricks can be used as a thermal insulation backing layer of refractory materials, and the application includes all kinds of industrial furnaces, hot blast furnaces, heating furnaces, smelting furnaces, flue pipes, hot air ducts, and other heating and heat-generating parts.
For Roller kilns, Tunnel kilns
Application positions: Furnace walls and bottom insulation layer of the ceramic roller kiln.
Substitute for the following: Lightweight clay brick, high alumina insulating brick, and mullite insulating bricks.
Advantages: not easy to shrink, not easy to pulverize, performance not easy to decay, and more cost-effective.
For Large Hot Air Ducts
Application positions: Insulation layer of a large hot air duct.
Substitute for the following: Lightweight clay bricks, high alumina poly-light bricks.
Advantages: lower outside wall temperature, more energy efficiency, lighter weight of thermal equipment, and more cost-effectiveness.
Rongsheng refractory manufacturers have been working hard to provide better refractory products for customers. Finally, we achieved a breakthrough in refractory insulation materials.
First of all, we can visually experience the advantages of our new thermal insulation bricks products through an experimental comparison picture below.
Then, By comparing with clay insulation bricks under the same experimental conditions, it can be found that our new high-temperature insulation brick product has a complete appearance and almost no change in size.
High-Temperature Micro-nano Insulation Bricks Wide Applications and Advantages
Our technical department announced some of its performance indicators: the bulk density can be ≤ 0.4 g/cm3 and thermal conductivity can be ≤ 0.11. It can work in the temperature range of 600-1400°C. Due to these advantages, the insulating bricks’ application advantages are as follows:
✔ Insulation layer of roller kiln, tunnel kiln walls, and bottoms. It is not easy to shrink, not easy to pulverize, and its performance is not easy to decay.
✔ Insulation layer for large hot air ducts. The outer wall temperature is lower and more energy-saving. Thermal equipment is lighter in weight and more cost-effective.
1. Reduce the outer wall temperature of high-temperature industrial kiln
The actual measured data when the wall thickness of two different materials is 300mm, the data are compared as follows:
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%↓.
2. Reduce the weight of the furnace body of the high-temperature industrial kiln
The actual measured data, when the temperature of the outside wall reaches 80°C, the data are compared as follows:
Using Rongsheng light-weight thermal insulation bricks, only 210mm thick (thin) is needed;
Using ordinary lightweight 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 the furnace wall by 57.14%↓.
Its high performance-price ratio will make it widely used in the insulation layer of more and more high-temperature industrial furnaces. Effectively reduce the temperature of the outer wall of the kiln, saving production energy and costs. Let Rongsheng help you better with the high-temp insulating bricks.
