Nano Insulation Board: The Next Generation High Temperature Thermal Insulation Solution for Industrial Energy Efficiency
【Summary】 Sanhe Nano Insulation Board provides ultra-low thermal conductivity, high temperature resistance, and energy-saving solutions for cement kilns, aluminum electrolysis, steel, and battery thermal protection applications.
Introduction
With increasing global demand for energy conservation, carbon reduction, and improved thermal efficiency, industries operating under extreme temperatures are continuously searching for more advanced insulation technologies.
Traditional insulation materials such as ceramic fiber, calcium silicate board, and lightweight refractory materials often face challenges including high thermal conductivity, large installation thickness, and performance degradation after long-term exposure to high temperatures.
Nano insulation boards (Microporous Insulation Boards)represent a new generation of high-performance thermal insulation materials. Through advanced nano-microporous technology, they provide extremely low thermal conductivity, excellent temperature resistance, and superior dimensional stability, helping industrial equipment reduce heat loss and improve energy efficiency.
What Is Nano Microporous Insulation Board?
Nano insulation board is an advanced inorganic thermal insulation material manufactured through nano-scale pore structure technology.
The internal microporous structure effectively suppresses the three major heat transfer methods:
- Thermal conduction
- Thermal convection
- Thermal radiation
By limiting gas molecule movement inside nano-scale pores and blocking infrared radiation, the material achieves outstanding thermal resistance performance.
Compared with conventional insulation materials, nano insulation boards can achieve the same insulation effect with significantly reduced thickness, making them ideal for applications where installation space is limited.
Key Advantages of Sanhe Nano Insulation Board
1. Ultra-Low Thermal Conductivity
One of the biggest advantages of nano insulation boards is their extremely low thermal conductivity.
Typical performance:
Thermal conductivity at room temperature: approximately 0.020 W/(m·K)
Thermal conductivity at 800°C: approximately 0.032 W/(m·K)
Compared with traditional insulation materials, heat transfer can be reduced significantly, improving overall equipment thermal efficiency.
2. High Temperature Resistance
Sanhe nano insulation boards are designed for demanding high-temperature environments.
Depending on different models:
SH950:
Continuous operating temperature: up to 950°C
Peak temperature resistance: up to 1200°C
SH1150:
Long-term service temperature: up to 1050°C
Excellent passive fire protection performance
These properties make nano insulation boards suitable for furnaces, kilns, industrial heating equipment, and thermal protection systems.
3. Thin Design, Space Saving
Compared with conventional insulation materials, nano insulation boards provide superior insulation performance with much smaller thickness.
Typical comparison:
| Item | Traditional Insulation | Sanhe Nano Insulation Board |
|---|---|---|
| Required thickness | 100 mm | 20–30 mm |
| Space saving | — | More than 70% |
| Thermal conductivity at 600°C | 0.15–0.25 W/(m·K) | <0.027 W/(m·K) |
This advantage is especially valuable in equipment upgrades, compact furnace structures, and industrial retrofit projects.
Applications of Nano Insulation Boards
1. Cement Industry
In cement production, rotary kilns and thermal processing equipment operate continuously at temperatures above 1000°C.
Heat loss from kiln shells directly affects:
Fuel consumption
Production efficiency
Equipment lifespan
Nano insulation boards are widely used in:
Kiln hoods
Kiln tails
Preheaters
Calciners
Tertiary air ducts
Clinker coolers
Practical applications show that nano insulation boards can reduce equipment surface temperature, improve heat recovery efficiency, and reduce thermal losses.
2. Aluminum Electrolysis Industry
Aluminum smelting requires reliable thermal insulation systems capable of resisting high temperatures and harsh chemical environments.
Nano insulation boards and vermiculite insulation materials are used in:
Electrolytic cell insulation systems
Furnace thermal barriers
High-temperature equipment insulation
For aluminum electrolytic cells, vermiculite insulation boards provide excellent resistance against fluoride and cryolite electrolyte penetration while maintaining stable thermal insulation performance.
3. Steel and Metallurgical Industry
Steel production equipment experiences extreme thermal cycling and significant heat loss.
Nano microporous insulation materials are applied in:
Steel ladles
Tundish systems
Torpedo ladles
Reheating furnaces
Benefits include:
Reduced shell temperature
Lower heat loss
Improved energy efficiency
Extended refractory service life
For example, nano insulation materials applied in steel ladles have demonstrated shell temperature reductions of approximately 80–100°C in practical applications.
4. New Energy and Battery Industry
With the rapid development of electric vehicles and energy storage systems, thermal safety has become increasingly important.
Nano insulation materials are used for:
Battery thermal protection
Energy storage systems (ESS/BESS)
Thermal barriers between battery cells
Sanhe nano insulation pads help reduce heat transfer between battery cells, delay thermal propagation, and improve system safety.
