Abstract

A CONTINUOUS METHOD FOR COAGULATING NATURAL RUBBER LATEX COMPRISES PASSING A STREAM OF LATEX THROUGH A VERTICAL COLUMN. THE LATEX TRAVELS DOWN THE COLUMN AS A THIN FILM ON THE INNER SURFACE THEREOF UNTIL IT COMES INTO CONTACT WITH STEAM WHICH HAS BEEN INJECTED INTO THE COLUMN. THE LATEX IS RAPIDLY HEATED BY THE STEAM AND COAGULATES, THE RESULTING COAGULUM BEING COLLECTED AT THE BOTTOM OF THE COLUMN. THE METHOD IS PARTICULARLY SUITABLE FOR THE COAGULATION OF EPOXIDISED NATURAL RUBBER LATEX. APPARATUS FOR PERFORMING THIS METHOD IS ALSO DESCRIBED.
