Heat preservation structure for spandex yarn heat-conducting pipeline

Abstract

The invention discloses a heat preservation structure for a spandex yarn heat-conducting pipeline. The heat preservation structure comprises the pipeline and a composite heat preservation structure body arranged on the outer surface of the pipeline. The composite heat preservation structure body comprises a high-temperature heat preservation layer, a rubber heat preservation layer and a reflectinglayer which are arranged in a laminated mode; the high-temperature heat preservation layer is arranged on the outer surface of the pipeline; a first heat-insulation material layer is arranged betweenthe high-temperature heat preservation layer and the rubber heat preservation layer, and a second heat-insulation material layer is arranged between the rubber heat preservation layer and the reflecting layer; a carbon fiber heat-insulation layer serves as the second heat-insulation material layer, a carbon dioxide aerogel heat-insulation layer serves as the first heat-insulation material layer,the thickness of the first heat-insulation material layer is 20-30 mm, and the thickness of the second heat-insulation material layer is 15-20 mm; and a paint-baked steel plate reflecting layer servesas the reflecting layer. The heat preservation structure for the spandex yarn heat-conducting pipeline is simple, and by using the composite heat preservation structure body, the heat preservation structure has the good heat preservation and heat-insulation effects.

Description

technical field [0001] The invention relates to the technical field of spandex yarn production, and more specifically relates to a thermal insulation structure for spandex yarn heat-conducting pipes. Background technique [0002] At present, in the spandex yarn textile production process, the spandex yarn is often processed by heating rollers, so as to improve the quality, smoothness and softness of the spandex yarn. In the spandex textile production process, steam treatment is usually required to improve the quality, smoothness and softness of spandex yarn. [0003] In the prior art, one of the methods is to use steam to process the spandex yarn, which requires the steam pipeline to have a good thermal insulation effect. However, the current existing heat-insulating materials applied to pipelines have complex structures, difficult installation, poor sealing performance, and unsatisfactory heat-insulating effects. [0004] For this reason, it is necessary to address the ab...
