MIXER Russian patent published in 1995 - IPC

FIELD: synthesis of thermostable fibres. SUBSTANCE: mixer has vertical case 1, in which agitator is positioned. Agitator has shaft 5 and mixing members arranged through the height and made of peripheral 7 and central 6 blades separated by partitions 8. All partitions are joined in series by continuous spiral strip 9. When rotating the agitator, the blades with partitions sink powder-like monomer at the expense of formation of intensive flows. Spiral strip imparts axial circulation to viscous solution. EFFECT: enhanced efficiency of synthesis of thermostable fibres. 2 cl, 4 dwg
