    摘要: The invention relates to a piston system (1) for use in a homogenizer, comprising a piston (2) that is configured and arranged to make a reciprocating movement in use of the piston system, a cylinder (3) that is configured and arranged to receive and guide at least a first part of the piston, a first supply channel (8) that is configured and arranged to supply a lubricating medium (9) to a portion (10) of the first part of the piston that in use is arranged inside the cylinder, and a second supply channel (13) that is configured and arranged to, in use, supply a cooling medium (14) to a second part of the piston outside the cylinder. Also disclosed is a process for the production of an elastomer agglomerate composition forcing a slurry comprising elastomeric particles through an aperture to obtain the elastomer agglomerate composition using the piston system.

    摘要: The invention relates to a process for the production of an elastomer agglomerate composition, comprising the steps of: (a) providing a slurry comprising elastomeric particles in water, wherein the slurry has a temperature of 40 to 80° C., wherein the elastomeric particles are selected from the group consisting of polybutadiene particles, poly(styrene butadiene) particles comprising at least 50 wt % of units derived from butadiene, poly(acrylonitrile butadiene) particles and polybutylacrylate particles and combinations thereof, and wherein the slurry is substantially free of chemical agglomerants, preferably the amount of the chemical agglomerants being less than 0.01 wt % with respect to the total of the solids content in the slurry and any chemical agglomerants; and (b) forcing the slurry through an aperture to obtain the elastomer agglomerate composition.
