Are you familiar with the new thermal insulation material - nano thermal insulation board?


With the rapid development of modern industry, the value of refractory materials is similar to high-speed gear lubricant. In order to ensure its safe and rapid development, the structure of the refractory industry has been adjusted several times, gradually changing from heavy Light, intense, functional changes, low thermal conductivity, small bulk density, multifunctionality - trends in the development of refractory materials in the future.

Among many high-temperature insulation materials, when the temperature exceeds 1000°C, ceramic fibers have the best thermal insulation performance, such as crystal fibers containing zirconium fibers, high alumina fibers, etc.; at temperatures less than 1000°C °C, nano-microporous thermal insulation The thermal insulation performance of the material is good, and the thermal conductivity is only 0.031W/mK (600℃ hot surface).

Nanoinsulation board

The main raw materials for nano thermal insulation boards are nano silica, nano alumina, zirconium dioxide, binder and so on.

The small size of nanoparticles in the nanosized inorganic refractory powder (particle size less than 20 µm) lengthens the heat conduction path, making heat conduction difficult.

The pores of Shengyang's nano-microporous insulation material have a maximum diameter of about 50 nanometers, which is less than the free path of gas convection (70 nanometers), and the gas inside is in a state of zero convection.

The added IR opacity agent is uniformly distributed in the nanoplate, and the heat transferred by the radiation is reflected, dissipated, and absorbed by the opacifying agent to a minimum.

The Nano Insulation Board adopts lightweight inorganic nano-SiO2 and low thermal conductivity ceramic fibers as raw materials, and high reflectivity aluminum foil as bottom material. and baking process after continuous mold coating.

Nanoplast application notes

Using temperature: The application point at which the energy-saving effect of the nano-microporous insulation board is most noticeable is between 600 to 800 °C on a hot surface;

Usage place: The microporous nanoplate should be placed between two layers of ceramic fiber materials, which has better energy-saving performance, and can also protect the nanoplate during construction, preventing external forces from damaging the internal structure of the nanoplate during construction and affecting the use effect.

Nano thermal insulation board has ultra-low thermal conductivity, which saves energy compared to traditional thermal insulation materials. Taking as an example a pipe with a diameter of 150 mm and a temperature of 600 degrees, when the thickness of the pipe is only one third of the thickness of traditional mineral wool, 1400 kilowatt-hours of electricity per meter of pipe per person can be saved. per year and about 140 kilowatt-hours of energy per year for a pipe with a total length of 1000 m. 10,000 kilowatt-hours of electricity.
