DEVICE FOR ISOLATING POLYMERS FROM HYDROCARBON SOLUTIONS Russian patent published in 1995 - IPC

FIELD: production of synthetic rubber. SUBSTANCE: pins of device are secured along concentric circumferences and free ends of pins are interconnected by rings. Cross section of pins is elliptical in shape with long axes of ellipses being positioned tangentially in relation to concentric circumferences. Such design allows application of mechanical strain onto rubber crumb in aqueous solution in means intended for exerting mechanical action upon polymer crumb in the process of two-step water degassing. EFFECT: improved efficiency of rubber crumb degassing process. 3 dwg
