Functional detachable thermal insulation sleeve

Abstract

The invention discloses a functional detachable thermal insulation sleeve. The functional detachable thermal insulation sleeve is suitable for the field of heat preservation of pipelines and equipment, the applicable temperature range is from -20 to 800 DEG C, and the thermal insulation sleeve comprises fixed buckles, an insulating composite layer and an outer protective layer; the fixed buckles are fixed to the outer protective layer of the thermal insulation sleeve and distributed on the opposite sides of the thermal insulation sleeve; the insulating composite layer comprises a basic thermalinsulation layer, a basic reflective layer, a second thermal insulation layer, a second reflective layer, a third thermal insulation layer, and a third reflective layer from the inside to the outside, and the insulating composite layer is of a multilayer composite structure which effectively enhances the thermal insulation effect; the insulating composite layer is formed by sewing. The functionaldetachable thermal insulation sleeve is manufactured and prepared by utilizing the portability of the fixed buckles and the excellent high temperature and heat preservation performance of the multilayer composite material and has extensive application value in the market.

Description

technical field [0001] The invention relates to the technical field of heat preservation of pipes and equipment, in particular to a functional detachable heat preservation cover. Background technique [0002] Insulation materials are divided into two categories: organic and inorganic: 1. Inorganic insulation materials, commonly used are foamed concrete, mineral wool, asbestos, glass wool, vermiculite, diatomaceous earth, expanded perlite and rock wool, etc.; 2. Organic insulation materials , with the development of the chemical industry, such as polyurethane rigid foam, etc. have been used in heating pipes. This thermal insulation material has low thermal conductivity, good corrosion resistance, low water absorption, light weight, high strength, and simple processing and molding, but the temperature resistance needs to be further improved. The insulation of heating pipes generally consists of two parts: insulation layer and protective layer. To prevent corrosion, first coa...

AI Technical Summary

Problems solved by technology

It has the advantages of energy saving and environmental protection, simple structure, good sealing, light insulation layer, no need to fill any heat insulation materials, and easy construction. However, its insulation effect needs to be improved, and the damage rate is high during the replacement process.

[0006] At present, the quality of pipe insulation materials in the market is uneven, the manufacturing cost is high, the life is short, especially the insulation performance is poor, the installation is complicated, and it consumes a lot of manpower and material resources. Therefore, research on low-cost, high-performance, and portable pipe insulation structures, Has a wide range of market application value
