A more efficient preparation of rubber-based adhesives through high-speed rubber cutting and dissolving
The rubber cutter blade should be equipped with sharp, saw-like teeth. In some processes, depending on the raw materials and the formulation requirements, the blade can be "open" and configured much like standard high-speed dispersers typically used in the coatings industry. Most rubber cutter arrangements include a stationary shroud around the blade, similar to a rotor stator or homogenizer-type arrangement. The shroud directs flow and funnels the circulating solids/solvent suspension back into close contact with the blade and the shroud, where further size-reduction takes place. When higher viscosities are involved or other parameters become factors, it becomes appropriate to consider a dual-shaft machine with a jacketed mixing vessel for heat-transfer needs.
