د پالتو لپاره د کرسټلینینګ کرښه

>> په لومړي ګام کې، د پالتو بیاپلانډ د IRD دننه د 15 دقیقو په جریان کې د IRD دننه کرسټیل شوی او وچ شوی دی. This crystallization and drying process is achieved by a direct heat-up procedure using Infrared radiation, to achieve a material temperature of 170˚C. In contrast to the slow hot-air systems, the quick and direct energy input facilitates a perfect egalisation of permanently fluctuating input moisture values – the control system of the IR radiations allows responding to altered process conditions within seconds. پدې توګه، د 5،000 او 8،000 ppm ترمنځ ارزښتونه د IRD دننه د IRD دننه د 8-50پم پاتې کچه ته راټیټیږي.

>>په IRD کې د کرسټالیز کولو پروسې ثانوي اغیزې په توګه، د ځمکې د موادو لوی کثافت ډیروي،په ځانګړي توګه د روښانه وزن فلیکس کې. This secondary effect is very interesting against the background that the tendency towards thin-walled bottles prevents the recycling material from achieving bulk densities of > 0.3 kg/dm³. An increase of the bulk density by 10 to 20 % can be achieved in the IRD, which appears to be insignificant at first sight, but improves the feed performance at the extruder inlet substantially – while the extruder speed remains unchanged, there is a substantially improved filling performance on the screw.
