Latex testing machine SECOMAK

(a.k.a the Klaxon Test Machine)


The latex rubber stability test machine / apparatus tests the mechanical stability of concentrated natural and synthetic latex rubber when subjected to high speed mechanical stirring or mechanical shear.


Stirring is applied to the latex rubber at a constant of 14,000 rpm until the end point, or latex instability is reached.


The approach to the end point is usually indicated by a drop in meniscus of the latex, loss of turbulence and a change in the sound of stirring action.


The end point is determined by the first appearance of small pieces of coagulated rubber.


This end point is confirmed by the presence of an increased amount of coagulated rubber after 15 seconds additional rotation.


The end point in this case is the presence of approximately 1% of coagulum based on total solids.
