摘要： Shear forces are used for essentially salt-free coagulation of plastics dispersions or rubber dispersions. For this, method of use is made of an apparatus with at least one shearing module which has a stator and a rotor arranged within the stator, where the surfaces facing toward one another in the stator and in the rotor are in each case smooth, or at least the rotor exhibits a structure formed on its surface and facing from this in the direction of the stator, and between the stator and the rotor there is a gap of predetermined gap width. The process is carried out by passing the dispersion to be coagulated through the gap between stator and rotor and precipitating the dispersion by rotation of the rotor with predetermined shear rate and shear deformation.

摘要： The invention relates to a process for the drying of coagulated water-containing rubber particles. These are treated with an aqueous solution of any desired substances in monodisperse solution in water in such a way that, at least for some period, the surface of the rubber particles is completely covered by the aqueous solution. It is preferable to use an aqueous solution of substances selected from the group consisting of salts, alcohols, acids and sugars. This method can reduce the internal water content between the particles resulting from coagulation, without major usage of energy or time.
