Abstract:
The invention relates to a method for treating a monomer, pre-polymer, polymer or a corresponding mixture, in particular for producing a dope for producing a polymer fibre, in particular a p-aramide fibre, in which the monomer, pre-polymer, polymer, additives or a corresponding mixture is admixed with a solvent, blended, fused, homogenised and/or degassed and then discharged, which takes place at least partially in a reactor (7), is to force-feed the monomer, pre-polymer, polymer or a corresponding mixture into the reactor (7) using a force-feed device (4).
Abstract:
In a method for implementing mechanical, chemical and/or thermal processes in a product which is located in a housing (1) with mixing and cleaning elements and/or transporting elements (6) on at least one shaft (4, 5), and is transported via said elements (6) from an inlet (2) to an output (10), the intention is for a cross section of the housing (1) to be adjusted in variable fashion at least once in the longitudinal direction thereof.
Abstract:
The invention relates to a device for treating a product that can be transported in a housing from an entry point to an exit point, particularly a torr factor for carrying out a roasting process utilizing a hardly flowable product forming nests and having no wall adhesion, wherein chambers are to be formed by disk-shaped elements disposed on a shaft.
