The reflection of aluminum foil

The reflection of aluminum foil

Aluminum foil also has a good reflection, aluminum foil surface more bright and smooth expansion, reflective performance is stronger!

The purity of aluminum material has obvious influence on the reflectivity of aluminum foil. When the impurities in the aluminum foil, impurity scattering will increase the absorption of radiation. To obtain high reflectivity aluminum foil, the purity should not be less than 99.6%.

The reflectivity of aluminum foil is also different

Due to the different surface smoothness of aluminum roll, the light reflectivity of aluminum foil is also different. When the foil surface is rough, 1235 aluminum foil, affected by the irradiation wavelength of the light reflectivity was the emergency plan, the overall trend is increased with the increase of the wavelength reflectivity increases, when the light wavelength is 6505m when the highest reflectance. However, with the increase of the wavelength of light, the reflectivity of the aluminum foil and the surface of the single side light decrease. Interestingly, when the irradiated light is tilted from the longitudinal direction, the reflectance of the dark surface is higher than that of the smooth surface.

What is the reflectivity of aluminum foil related to?

When the light is irradiated from the side of the aluminum foil, the reflectivity of the smooth surface is higher than that of the dark surface. For smooth aluminum foil investment field, horizontal vertical reflectivity is 10% higher than that of the light reflection ability of aluminum foil is particularly strong. The reflectivity of light is related to the purity of aluminum foil, flatness, surface roughness and heat ray wavelength.

With the increase of the purity of aluminum foil and the increase of the thermal wavelength, it is expected that the reflectivity of aluminum foil will increase. With the decrease of flatness and the increase of surface roughness, the reflectivity of aluminum foil is reduced.
