Adiabatic principle Material properties |
Reduce conduction heat
There are infinitely many nanopores in nano-insulation materials, the density is very small, and the heat flow can only be along the gas
Pore wall transfer and long path stiffening effect greatly reduce the heat conduction capability.
Restricted convection
The average diameter of the pores of the nano thermal insulation material is 2-50mm, which is much smaller than the free collision path of air molecules 70mm.
Making air molecules lose their ability to flow freely and limiting their participation in heat convection.
Partition heat radiation
The inner wall of the pores of the nano-porous adiabatic material shows an infinite number of refracting and reflecting surfaces, which can block the thermal radiation well.
Small thermal conductivity, more energy saving
The thermal conductivity of nanometer adiabatic material is only 1/5-1/3 that of the traditional material, which not only reduces the heat loss effectively, but also improves the space utilization. As can be seen from the table, when the temperature is more than 100 degrees, the performance advantage of nano-insulation materials is more obvious. The use of nanomaterials reduces heat dissipation area and heat loss, which is beneficial to energy saving and steam long-distance transportation.
Super waterproof fire performance
Nano adiabatic material hydrophobicity can reach more than 99%, showing lotus leaf effect, grade A noncombustible standard to avoid material due to water caused by settlement, adiabatic performance decline. At the same time, the fire rating for the national building materials Class A non-combustible standard, can withstand -200 degrees of ultra-low temperature to 800 degrees of high temperature, the performance of the material does not change.
Long service life
The nanometer adiabatic material has no obvious change in appearance under the condition of 1.78kGy irradiation dose. The life of the product was measured using Arrhenius research method. The test showed that the aerogel was used at 350℃ for 20 years, and the shrinkage rate was less than 2%.
Good soundproof effect
Extremely low sound wave transmission speed, about 100 m/s, sound insulation capacity up to 44dB, can be used as efficient sound insulation material.
Green environmental protection
The material is composed of inorganic materials, and it does not contain any substances harmful to human body through SGS test. The material contains very little soluble chloride ions and has no corrosion to the equipment and pipes for a long time.
Construction is convenient
The density of nanometer adiabatic material is about 200Kg/m3, the tensile strength is more than 200KPa, and the compression springback rate is more than 90%. It has good flexibility, high tensile strength, box cutter cutting, convenient construction
