Abstract: Vents and micro-structures of rubber molds may become clogged with rubber that is difficult to remove. These vents and micro-structures can be cleaned of rubber, even if heat aged, by subjecting the mold to high temperatures in the presence of a solvent to devulcanize any rubber present. If the rubber used with the mold being cleaned includes carbon black, a solvent may be used to dissolve the devulcanized polymer, leaving the carbon black which can be removed by water jets or other cleaning means.

Abstract: A dual vessel reactor and a method of carrying out a reaction using a dual vessel reactor are provided using a non-condensable gas to substantially isolate the inner vessel from the outer vessel during the reaction and limit the heating of the outer vessel when steam from the inner vessel condenses on the interior surface of the outer vessel. By limiting the heating of the outer vessel through the condensation of the steam or other vapour from the inner vessel, the operating temperature of the outer vessel is kept below an upper threshold of the operating temperature of a seal used to seal the door in the outer vessel.

Abstract: A method for the controlled removal of water from devulcanized rubber, comprising steps of contacting the devulcanized rubber with a solvent, dissolving the water out of the devulcanized rubber and into solution without removing other components in the rubber such as polymer, separating the devulcanized rubber from the solvent, and drying the devulcanized rubber. By controlling the amount of water that is in the solvent-solution, and/or the amount of time the devulcanized rubber is in contact with the solvent solution the amount of water that is removed can be controlled. By controlling the amount of water that is removed the rheology/viscosity (e.g. G′ and G″) of the devulcanized rubber can be controlled.
