Nano board is a new type of thermal insulation material manufactured with the latest high-tech technology, and its thermal conductivity is smaller than that of still air. Under high temperature conditions, the heat insulation performance is 3 to 4 times better than traditional fiber insulation materials. Nano board has a significant energy saving effect. It has the characteristics of light weight, high temperature resistance, simple processing and fast construction.material.

The nano board has ultra-low thermal conductivity, can greatly save energy compared with the traditional heat insulation material.

This product has been widely used in aerospace, military industry, machinery, ceramic chemical metallurgy, electrical appliances and other complex thermal engineering equipment, which has solved many worldwide problems. The product packaging has glass fiber cloth, aluminum foil and waterproof plastic film, which can be bent for construction.

It can replace traditional thermal insulation materials, opening up a new way of thermal insulation technology.

(1) Prevent thermal movement of gas molecules

According to the theory of molecular thermal motion, the heat transfer of gas is mainly through the collision of higher-speed molecules on the high-temperature side to lower-speed molecules on the low-temperature side, and the heat is transported step by step. If a series of barriers are established in the direction of the temperature gradient and the barrier distance is less than the average free path of the gas molecules, and the barriers are closed and close to the pores in the vacuum state, it will effectively prevent the thermal movement of the gas molecules.

(2) Reduce heat conduction

The thermal conductivity of nanoporous silicon micropowder is 0.016～0.024W/m.k, which is the super thermal insulation material with the lowest thermal conductivity. For aluminum foil with a thickness of only 6 to 10 μm, the thermal conductivity is 0.038 to 0.042 W/m.k, which is a very good thermal insulation material.

(3) Insulation radiation

The composite reflective insulation panel is composed of nano-SiO2 and aluminum foil. The multi-layer aluminum foil plays the role of reflecting heat radiation with a reflectivity of more than 87%, and at the same time plays the role of isolating heat conduction, heat convection and heat radiation.
