    Theoretical and experimental investigation of the die drool phenomenon for metallocene based LLDPE

  • Original language description

    Die drool phenomenon has been experimentally investigated for metallocene based LLDPE on the specially designed annular extrusion die.The flow at the end of the die has been analyzed theoretically by the FEM employing modified White-Metzner model as theconstitutive equation. It has been revealed that the negative pressure occurs at the die lip area which seems to be driving factor for the die drool phenomenon

    Teoretická a experimentální analýza fenoménu die drool pro metalocenový LLDPE

  • Czech description

    Die drool byl experimentálně analyzován pro metalocenový LLDPE na speciálně vyrobené kruhové vytlačovací hlavě. Výtok taveniny byl teoreticky analyzován pomocí FEM a modifikovaného White-Metznerova modelu. Bylo zjištěno, že řídícím parametrem pro jev Diedrool je sací efekt na výstupní štěrbině.
