摘要: The present invention describes an approach to the design of temperature regulation systems combining, in a single structure, a heat absorption or release system by fusion or solidification of a particular material and also a particulate oxide that contributes to reflecting infrared radiation. The production of the thermofunctional nanostructure comprises six successive processing steps: a) pre-emulsifying the organic material and dispersing the colloidal oxide nanoparticles in an aqueous phase, the pre-emulsion; b) reducing droplet size in the pre-emulsion by high-pressure homogenisation; c) adsorbing the monomer in the resultant emulsion; d) polymerising and forming thermoftmctional nanostructures; e) cooling the nanosuspension containing the thermofunctional structures; and optionally f) drying the product. The resultant thermofunctional nanostructure can be in the form of a colloidal dispersion in an aqueous medium or of a nanoparticle powder, if the aqueous nanostructure dispersion is subjected to a drying process. This thermofunctional nanostructure can be applied to obtain products in the fields of cosmetics, pharmaceuticals, medical equipment, prostheses, textiles, paints, coatings, composites, packaging, civil engineering, electrical or electronic equipment, the automobile and paper industries.

摘要: The present invention refers to a machine for cutting the external coating and methods for removing the Coated Pipe Preservation System for Onshore and Subsea Pipelines, called, for short, PPS System or PPS, represented in FIGS. 1 (1.1), (1.2), (1.3), and (1.4). This Machine, called the PPS Stationary Cutting Machine, represented in FIGS. 7 and 8, in addition to performing the cut at the correct angle (β), represented in FIG. 2 (2.4), makes the FBE Exposure Band (FBE Tail), represented in FIG. 2 (2.3), in order to ensure that the Collar (Cutback), represented in FIG. 2 (2.2), meets the specifications regarding dimensions (C) and (T), represented in FIGS. 2 (2.6) and (2.7), and the finishing at the interface with the Pipe External Coating, being applicable to straight pipes that rotate during the cutting of the external coating. The PPS Automated Drawing Device, represented in FIGS. 9 and 10, used together with the PPS Stationary Cutting Machine, is intended to draw and/or reposition the PPS System in an automated manner through the Cover (1.3, 8.3, and 9.5), increasing productivity and operational safety.
Together with the PPS Automated Drawing Device, the assembly is installed in the PPS Cutting and Drawing Stations, represented in FIGS. 11 to 14, to be implanted in Onshore Bases (Spoolbases) (11), Type J (J Lay) (12) Launch Vessels, and Type S (S Lay) Launch Vessels (13), for the Construction and Installation of Subsea Pipelines (Subsea or Submerged Pipelines), and at the Pipe Sites (14), for Onshore Pipelines (Buried Pipelines).-

摘要: The present invention relates to a nanoencapsulated temperature regulating agent which presents a nanoencapsulated temperature regulating agent (ARTN/NTRA) that aggregates, in a same nanostructure, an organic material capable of undergoing melting by absorbing heat, or solidification by releasing heat, and IR radiation screening nanoparticles, a colloidal oxide capable of reflecting the infrared radiation which causes surfaces exposed to a heat source to heat up. The NTRA produced may be either in the form of a colloidal dispersion in an aqueous medium or in the form of nanoparticles, if the aqueous dispersion of the NTRAs is subjected to any drying process such as spray-drying, fluidized-bed drying, filtration, lyophilization, centrifugation, inter alia. The association of temperature regulating mechanisms and the fact that the NTRA is on a nanometric scale imparts greater efficiency for heat transfer processes and surface-covering power, guaranteeing greater reflection of infrared radiation. By virtue of its versatility and different forms of presentation, this NTRA makes it possible to obtain different types of products for use in the cosmetics, pharmaceuticals, medical equipment, prostheses, textiles, paints, coatings, composites, packaging, civil engineering, electrical or electronic equipment, automobile and paper-making industries.
