A new irradiation device for medium scale plastic products

  • A new irradiation device for the exposure of plastic products is presented. Developed in the BAM division 3.1 "Dangerous Goods Packaging" it can be used for artificial UV irradiation of plastic Containers filled with hazardous liquids. Present regulations and tests only investigate the exposure effects of UV and of media separately, but as the damaging effect is expected to be synergistic for at least some media, a combined test was looked for. A chamber of 60 cm by 60 cm base area and 1 m height gives space for up to 40 cm wide objects. Two fluorescent UV lamp arrays are arranged on opposite walls, separated from the chamber by quartz glass panes. By continuously rotating the exposure object by means of a rotary disc that the object is placed on, spatial irradiation homogeneity is achieved over the exposure duration. The spectral irradiance of the chosen UVA 340 nm lamps gives the best match of global solar radiation in the short wavelength ränge.

The spectral irradiance of the chosen UVA 340 nm lamps gives the best match of global solar radiation in the short wavelength ränge. The close arrangement of the UVA lamps (15 each side) results in 60 W m'2 UV irradiance. Constant temperature is adjusted to typically 40 °C by the control of the fan speed. This temperature is chosen, as it is the required temperature for three week storage of filled polyethylene Containers, for proving Chemical compatibility in the field of dangerous goods. To ensure homogeneity, an interiorfan provides for air circulation.zeige mehrzeige weniger
