What is a Microporous Board?

1. Introduction

At a time of rising energy costs and increasingly stringent requirements for energy conservation in industrial production, highly efficient thermal insulation materials have become the focus of attention in many industries. Nano-microporous insulation boards stand out with their excellent thermal insulation performance. Did you know? In the steel smelting process, the use of nano-microporous insulation boards can reduce the heat loss of the furnace by about 30%, which not only saves energy, but also significantly improves the production efficiency. So, what exactly is a nano-microporous adiabatic plate?

Microporous Board1

Nano-microporous insulation boards are high-performance insulation materials that play a key role in a wide range of fields. From high-temperature industrial production to low-temperature cold-chain logistics, from building fire prevention to equipment protection, nano-microporous insulation boards have demonstrated their unique value, which is significant for improving product quality, ensuring safety, and improving energy efficiency.

2. Composition and structure

(1) Main components

Nano-microporous insulation boards are mainly composed of pyrolytic silica, with the addition of infrared shading agents such as silicon carbide (SiC), zirconium silicate (ZrSiO₄), alumina (Al₂O₃) and reinforced by special fibers. Pyrolytic silica is the basic structure, providing a stable physical support for the sheet. The infrared shading agents effectively block and reflect infrared rays, reducing the transfer of heat radiation. Special fibers, on the other hand, enhance the overall strength of the sheet, making it more durable in various application scenarios.

 (2) Nanopore structure

Nano-microporous insulation boards have a unique nanopore structure with a pore size of about 20 nanometers. This tiny pore size is like countless tiny “air traps”, which can lock the gas molecules firmly. The gas molecules are unable to move freely, thus greatly inhibiting internal convection. At the same time, the nanoscale structure reduces the path of heat conduction, reduces the heat conduction inside the material, as in the heat transfer road set up a heavy barrier.

3. Principle of Thermal Insulation

Principle of Thermal Insulation

(1) Reduce heat conduction

Compared with traditional thermal insulation materials, the microstructure of nano-microporous insulation board greatly reduces the path of heat conduction. There are more solid connection points inside the traditional materials, and heat is easily conducted through these points. The nano structure of the nano-microporous adiabatic plate makes the contact points between the solids greatly reduced, effectively reducing the heat conduction efficiency, so that the heat is difficult to pass in the material.

(2) Suppression of convection

The small nanometer-sized holes inside restrict the gas molecules to a very small space, and the gas cannot form convection circulation. This is like dividing the air into countless tiny “islands”, each of which is unable to exchange heat with the rest of the air, thus preventing the heat from dissipating by convection.

(3) Blocking thermal radiation

Added infrared shading agents play a key role in high-temperature environments. They effectively block and reflect infrared rays, reducing the transfer of heat in the form of radiation. In a high-temperature environment such as a glass manufacturing furnace, IR shading agents can block a large amount of heat radiation, improving the insulation of the furnace and reducing energy consumption.

4. Types and grades

(1) Common types

There are various types of nano-microporous insulation boards . Rigid boards and boards are suitable for use where precise installation and a stable structure are required, such as the lining of industrial furnaces. Flexible felts and blankets, on the other hand, can be easily adapted to complex shapes and are commonly used in curved areas of pipes and equipment. Customized shapes are available to meet the unique needs of special equipment, while granular nano-microporous materials are used to fill irregular spaces and gaps.

(2) Different grade characteristics

Grades of nanoporous insulation boards are categorized primarily based on their temperature resistance and compositional differences. For example, the MIP – 950 grade, which can withstand temperatures up to 1000°C, consists of fumed silica particles (7 – 12 nm) and is the standard grade for a wide range of applications, while the MIP – 1050 grade, which uses nano-sized (SiO₂) and (ZrSiO₄), is suitable for industrial applications at higher temperatures, and the MIP – 1150 grade, which uses nano-sized alumina, can withstand extreme temperatures. MIP – 1150 grade is made of Aluminum Oxide Nanoparticles, which can withstand extreme high temperatures and meet the most demanding high temperature environments.

5. Performance and Advantages

(1) Ultra-low thermal conductivity

The nano structure of nano-microporous insulation board makes its thermal conductivity extremely low, even lower than that of static air. This means that its thermal insulation effect is 3 to 6 times higher than that of traditional materials. In practical applications, using the same thickness of nano-microporous insulation board and traditional insulation materials, nano-microporous insulation board can block heat transfer more effectively and reduce energy consumption.

(2) Excellent high temperature stability

This sheet can maintain excellent thermal insulation performance at temperatures as high as 1200°C. In high temperature reactors in the petrochemical industry, nano-microporous insulation boards can withstand harsh high-temperature environments to ensure stable operation of the equipment, while maintaining good thermal insulation to improve the safety and efficiency of the production process.

(3) lightweight and efficient

Nano-microporous insulation boards achieve the same thermal insulation effect as traditional materials while reducing weight by more than 50%. In weight-sensitive areas such as aerospace and transportation, this lightweight feature not only helps reduce energy consumption, but also improves the overall performance of the equipment.

(4) Environmentally friendly and non-toxic

Nano-microporous insulation boards are free of harmful fibers and toxic substances, meet environmental standards, and can be recycled. This makes it an ideal choice for various industries under the concept of sustainable development, which not only meets the production needs, but also reduces the negative impact on the environment.

(5) High resistance to thermal shock

Its robust composition allows it to remain stable in environments with rapid temperature changes. In the process of steel production, frequent temperature fluctuations are a great test for the insulation material. With its excellent thermal shock resistance, the nano-microporous insulation board can withstand such a test to ensure the normal operation of equipment and reduce maintenance costs.
