Abstract
The invention relates to a composite thermal insulating structure, in particular to a composite thermal insulating structure for a high-temperature pipeline. The composite thermal insulating structure wraps the periphery of the pipeline, and the composite thermal insulating structure is composed of a nanometer-scale rare earth thermal insulating structure coating layer, a polyphenyl granule layer and a foaming polyurethane layer from outside to inside in sequence. A bonding layer is arranged between the nanometer-scale rare earth thermal insulating structure coating layer and the pipeline. The thickness of the nanometer-scale rare earth thermal insulating structure coating layer is 1-7cm, the thickness of the polyphenyl granule layer is 2-4 cm, and the thickness of the foaming polyurethane layer is 2-3 cm. The thickness of the bonding layer is 1mm. The composite thermal insulating structure for the high-temperature pipeline has the advantages that due to the fact that the nanometer-scale rare earth thermal insulating structure coating layer, the polyphenyl granule layer and the foaming polyurethane layer are used in a matched and mutually-bonded mode, the thermal insulating effect is good and installation is easy.
Description
technical field [0001] The invention relates to a composite thermal insulation structure, in particular to a composite thermal insulation structure for high-temperature pipelines. Background technique [0002] The temperature of the transport medium in industrial pipelines varies greatly. According to the temperature of the transport medium, the pipeline can be divided into low temperature pipeline, normal temperature pipeline, medium temperature pipeline and high temperature pipeline. Among them, rock wool, calcium silicate and aluminum silicate are generally used for thermal insulation of high-temperature pipelines. The thermal insulation effect is not good. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a composite thermal insulation structure for high-temperature pipelines. The structure has good thermal insulation effect, is easy to install, and is not easy to fall off. [0004] The te...
