Technical Field
The invention relates to the energy-saving and environment-friendly industry, in particular to a method for paving an aluminum foil on a prefabricated curve groove concrete insulation board.
Background
The prefabricated groove heat-insulation board is a general name of a floor heating module in ' technical rules of radiation heating and cooling ' released by housing of the people's republic of China and ministry of urban and rural construction. The prefabricated groove heat-insulation board is a template which is prefabricated into grooves with fixed intervals and sizes in a factory and has a load-bearing function, and is used for laying heating pipes or heating cables in the grooves after being assembled on site.
The concrete insulation board is a lightweight porous concrete board which is prepared by adding a foaming agent into slurry prepared from a cement-based cementing material, aggregates, an admixture, an additive, water and the like, mixing, stirring, casting and forming, and performing natural or steam curing, and is also called as a foam concrete insulation board. The concrete heat-insulation board has the excellent characteristics of light weight, good heat-insulation performance, sound absorption and insulation, fire prevention and the like, is suitable for outer wall heat insulation and a fireproof isolation strip thereof, is also applied to floor heating heat insulation engineering, has the advantages of energy conservation and environmental protection, low carbon and waste utilization, no toxicity and no harm, can utilize industrial waste residues, and can promote sustainable development. The concrete insulation board is one of the leading products of building insulation, and is more and more widely applied to the installation of floor heating.
In order to better realize energy conservation and emission reduction, a metal heat conduction layer of a groove with the same size as the outer diameter of a heating pipe is paved on a prefabricated groove heat insulation board used in floor heating installation engineering, the heat energy below is reflected to the upper side as much as possible for utilization, and the heat supply efficiency can be improved. This heat-conducting layer adopts the aluminium foil usually, and it is very easy to adopt the aluminium foil to lay the heat-conducting layer in sharp slot, because the aluminium foil does not have flexibility and ductility, when laying the aluminium foil as the heat-conducting layer on curve slot foam concrete heated board, the aluminium foil of pressing into curve slot often tears easily because the ductility is not enough, influences the heat conduction effect. At present, no good method exists for paving an aluminum foil heat conduction layer on a prefabricated curve groove concrete heat insulation plate. There is also a method of spraying a heat-conducting coating by adding an adhesive to high heat-conducting metal powder, but the cost of manufacturing the heat-conducting coating by using the metal powder is very high, and the heat-conducting performance of the adhesive is difficult to ensure because the adhesive often has a heat-resisting function.
