P: Mongobo oa ho qetela oo u ka o fumanang ke ofe? A na u na le meeli ho mongobo oa pele oa thepa e tala?
A: Mongobo oa ho qetela oo re ka o fumanang ≤30ppm (Nka PET e le mohlala). Mongobo oa pele o ka ba 6000-15000ppm.
P: Re sebelisa Double parallel screw extruding le vacuum degassing system bakeng sa PET Extrusion granulating line, na re ntse re hloka ho sebelisa pre-dryer?
A: Re fana ka maikutlo a ho sebelisa Pre-dryer pele ho extrusion. Hangata sistimi e joalo e na le tlhoko e tiileng ea mongobo oa pele oa lisebelisoa tsa PET. Joalo ka ha re tseba PET ke mofuta oa thepa e ka monyang mongobo o tsoang sepakapakeng e tla etsa hore mohala oa extrusion o sebetse hampe. Kahoo re fana ka maikutlo a ho sebelisa pre-dryer pele ho sistimi ea hau ea extrusion:
