International Classification:

G05B 13/02

US Classification:

700104, 700111

Abstract:

A method to evaluate, determine and optimize production parameters for a coating application of a UV cationic polymerizable coating system to a substrate is provided. The method is based on a simulation model which includes both shadow and dark cure processes. Both of an active center generation process and the active center diffusion process are mathematically described. In the model, the two processes are considered separately since they are driven by different fundamental phenomena and occur on different timescales. Evaluation or prediction of the effect of process variables on the curing of a cationic coating of a complex substrate according to the described method allows characterization and understanding of process variables which may save set-up costs and improve production efficiency.

Abstract:

A method for depolymerizing rubber tires. Rubber fuel may be pyrolyzed to produce a recovered carbon containing strands responsive to a magnet and vaporized rubber-derived compounds containing particulate material. The vaporized rubber-derived compounds containing particulate material may be passed through a cyclone to separate the particulate material from the vaporized rubber-derived compounds. The vaporized rubber-derived compounds may be contacted with a first liquid hydrocarbon material having a first boiling point to at least partially condense the vaporized rubber-derived compounds and produce a first liquid hydrocarbon product and a first residual vapor. The first liquid hydrocarbon product, the first residual vapor, and the recovered carbon may be separately recovered.

US Classification:

430324

Abstract:

The invention relates to a method for applying a photo-activated layered polymer coating to a substrate material in which one or more layers do not contain photoinitiator, or are not exposed to initiating light, but cure due to migration of cationic active centers. At least two separate monomer layers are applied to the substrate material. At least one of the monomer layers includes a photoinitiator capable of producing cationic active centers. The at least one layer including the photoinitiator is exposed to a source of UV radiation at a desired wavelength forming cationic active centers. The at least two separate monomer layers react in a polymerization reaction forming a cured layered material. The cationic active centers of the exposed monomer layer migrate to the unexposed layer such that both layers cure via the polymerization reaction.
