Problems solved by technology

The existing reflective layer for long-distance heating network mainly uses 802, 804 and 902 high-strength glues to bond glass fiber cloth and aluminum foil, but these three kinds of glues are blackened or even carbonized at high temperatures, and the glue bonding effect It will completely fail; at the same time, the existing production process of the aluminum foil reflective layer is not perfect, especially the glue drying speed of the aluminum foil and the glass fiber cloth is slow, which affects the production speed of the product; in addition, the glue application method on the production line mainly adopts the rolling method If this method is used, the glue will be applied unevenly due to the large area of ​​glue curing and poor fluidity, which will lead to poor performance of subsequent products, resulting in waste of high temperature resistant glue and increasing the cost of the enterprise.

Embodiment 1

[0040] Through the test in the heat network test device, when the central temperature of the DN400 steam pipeline is 420 °C and the ambient temperature is 25 °C, the reflective layer mass-produced by the company with patent authorization publication number ℃N205579044U is used. The temperature difference between the front and back of the reflective layer is about 5 °C. After the test, the adhesive of the reflective layer disappeared completely, and the aluminum foil and the glass fiber cloth were separated.

Embodiment 2

[0042] like Figure 4 As shown, through the test in the heat network test device, when the central temperature of the DN400 steam pipeline is 420 ° C and the ambient temperature is 25 ° C, the high temperature resistant reflective layer provided by the present invention is used, and the thickness of the high temperature resistant flame retardant adhesive 3 is 0.5mm. , The temperature difference between the front and back of the reflective layer is about 21 °C, and the reflective layer is not damaged after the test.

Embodiment 3

[0044] like Figure 4 As shown, through the test in the heat network test device, when the central temperature of the DN400 steam pipeline is 420 ° C and the ambient temperature is 25 ° C, the high temperature resistant reflective layer provided by the present invention is used, wherein the thickness of the high temperature resistant flame retardant adhesive 40 is 0.7 mm, the temperature difference between the front and back of the reflective layer is about 26 °C, the reflective layer is not damaged after the test, and the energy saving effect is remarkable.

Abstract

The invention discloses a special reflective layer production system for a long heat transmission network, the special reflective layer production system comprises a glass fiber cloth conveying device1, an aluminum foil conveying device 2, a pressing device 3 and a finished product conveying device 4, the glass fiber cloth conveying device 1 and the aluminum foil conveying device 2 are respectively arranged on two sides of the pressing device 3. The pressing device 3 comprises rolling a guide roller 38 and a rolling roller 39 which are arranged up and down. And after glass fiber cloth 5 conveyed by the glass fiber cloth conveying device 1 and an aluminum foil 6 conveyed by the aluminum foil conveying device 2 are pressed by the pressing device 3 to form a high-temperature resistant reflective layer 7, and the high-temperature resistant reflective layer 7 is conveyed from the pressing device 3 to a winding device 23 for storage. The special reflective layer production system is beneficial to improving the adhesiveness of the high-temperature resistant reflective layer, the production efficiency can be improved by 3-6 times, and meanwhile, the usage amount of high-temperature glue is reduced, and the special reflective layer production system is a resource-saving and environment-friendly production method.

Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to a special reflection layer production system for a long-distance heat transmission network. Background technique [0002] The reflection layer of the long heat transmission network is an indispensable and important part of the heat network pipeline engineering. When used, it can reduce the use of thermal insulation materials and save the installation space, which is suitable for a wide range of use. The existing special reflective layer for long heat transmission net mainly uses 802, 804 and 902 high-strength glues to bond glass fiber cloth and aluminum foil, but these three kinds of glues are blackened or even carbonized at high temperature, and the glue has a bonding effect. At the same time, the existing production process of aluminum foil reflective layer is not perfect, especially the drying speed of the glue sticking aluminum foil and glass fiber cloth is slow,...
