EXPERIMENTAL DETERMINATION OF ABSORPTIVITIES FOR OUTSIDE SHEETS OF FREIGHT CONTAINERS TO SOLAR RADIATION

Absorption of solar radiation by typical outside sheets (painted iron, non-painted aluminium and reinforced plastic) of freight containers have been measured. The values of painted iron sheets vary with their colors, ranging, from the largest value of dark blue, the second of red and brown, the third of green, orange and blue to the smallest of white. Aluminium sheet (not painted) has very small absorptivities, but the value of a dusty one increases with the amount of dust covering the sheet. The value of an oxidized or scratched surface of an aluminium sheet is larger than that of a nonpainted aluminum sheet. Absorptivities of canvas (vinylon and pure-cotton) have also been measured. The value of pure cotton is the largest (nearly equal to 1.0) in the day time of a calm day, decreasing with the increase of wind speed. While the deckstowed container is being transported in the sunlight, the roof of a container sometimes has a very high temperature, often resulting in cargo damage in the container. Making use of the absorptivities obtained by this experiment, the tempertures of the inside and the outside of a container will be analytically estimated by using the thermodynamic and related equations.
