CN102937226A - Outer thermal-insulation film of heating pipeline - Google Patents

Abstract

The invention relates to an outer thermal-insulation film of a heating pipeline, belonging to the technical field of thermal-insulation films. A first bonding agent layer is arranged outside a first heat-insulation layer, a second heat-insulation layer is arranged outside the first bonding agent layer, a second bonding agent layer is arranged outside the second heat-insulation layer, and an outer protection layer is arranged outside the second bonding agent layer. The outer thermal-insulation film of the heating pipeline has the beneficial effects that a design of two layers of heat-insulation thermal-insulation layers is adopted, the heat-insulation thermal-insulation effect is good, the overmuch heat loss in a heat transport process is avoided, the heat supply efficiency is improved, and the energy resource is saved.

Description

The outer thermal insulation film of heating pipeline

?

Technical fieldThe present invention relates to the outer thermal insulation film of heating pipeline, belong to the thermal insulation film technical field.

Background techniqueThermal insulation film arises at the historic moment for preventing heat loss, heating pipeline is the visual plant of north heating in winter, in the heat delivery process, itself has heat loss pipeline, in order to reduce the heat loss amount, usually can be provided with thermal insulation layer in pipeline, the long-term use of pipeline worn out, inner thermal insulation layer is damaged, and causes losing heat insulation effect, wastes energy; For preventing that this situation from producing, on the outer wall of pipeline, can twine again thermal insulation film, traditional heating pipeline thermal insulation film is because being heated for a long time, and is easily aging.

Summary of the inventionIn view of the defective that prior art exists, the purpose of this invention is to provide the outer thermal insulation film of heating pipeline of a kind of long service life, high insulating effect.

For achieving the above object; the technology used in the present invention solution is: the outer thermal insulation film of heating pipeline; the first insulating is outward the first sticker layer; the first sticker layer is outward the second insulating; the second insulating is outward the second sticker layer, and the second sticker layer is outward external protection.

The outer thermal insulation film of heating pipeline, its beneficial effect is: adopt two-layer insulating design, make heat insulation and preservation effect better, avoid too much heat loss in the pipeline heat energy transportation process, improve heat supply efficiency, energy saving.

Description of drawings

Fig. 1 is the structural drawing of the outer thermal insulation film of heating pipeline.

Fig. 1 reference character is as follows: 1, the first insulating, the 2, first sticker layer, the 3, second insulating, the 4, second sticker layer, 5, external protection.

Embodiment

Outside the heating pipeline that Fig. 1 shows in the structure diagram of thermal insulation film; its main structure comprises: be the first sticker layer 2 outside the first insulating 1; the second insulating 3 outside the first sticker layer 2; to be external protection 5 outside the second sticker layer 4, the second sticker layers 4 outside the second insulating 3.

Claims (1)

1. the outer thermal insulation film of heating pipeline; it is characterized in that: the first insulating (1) is outer to be the first sticker layer (2); the first sticker layer (2) is outer to be the second insulating (3); the second insulating (3) is outer to be the second sticker layer (4), and the second sticker layer (4) is outer to be external protection (5).
