Description

Technical Field

[0001] This utility model belongs to the technical field of rock wool, specifically relating to an industrial insulation rock wool for use in industrial pipelines and equipment insulation. Background Technology

[0002] Rock wool boards are widely used in building and industrial insulation due to their excellent fire resistance, thermal insulation, heat insulation, and sound absorption properties. In the industrial sector, rock wool is commonly used for insulation of pipes, tanks, and equipment. For example, the "Industrial Equipment Pipeline Insulation Standard" stipulates that pipes with an external surface temperature exceeding 50°C must be insulated. Existing industrial insulation rock wool includes rock wool felt, with an aluminum foil layer on the outside of the rock wool felt.

[0003] In practical applications, industrial insulating rock wool is wrapped around the outside of pipes and then secured to the outside with wire. However, when using wire for binding, the two ends of the wire are often twisted together. For safety reasons, the twisted wire is then bent towards the aluminum foil layer. Because the aluminum foil layer has weak puncture resistance, bending the twisted wire towards it can easily cause the ends of the wires to puncture the aluminum foil layer.

[0004] Because the aluminum film layer has a moisture-proof function, if the aluminum film layer is damaged, water vapor will enter the rock wool layer, causing the thermal conductivity of the rock wool layer to increase significantly, thus affecting the insulation effect. Utility Model Content

[0005] The purpose of this invention is to provide an industrial thermal insulation rock wool that can prevent the ends of the iron wires from puncturing the aluminum film layer when the iron wires are bent together and brought close to the aluminum film layer.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An industrial thermal insulation rock wool includes a rock wool layer, an aluminum film layer on the outside of the rock wool layer, and rock wool strips on the outside of the aluminum film layer. The rock wool strips do not completely cover the aluminum film layer in the circumferential direction. The density of the rock wool strips is greater than that of the rock wool layer. The ends of metal wires that are circumferentially wound around the aluminum film layer and the outside of the rock wool layer are intertwined, and the intertwined ends of the metal wires are located on the outside of the rock wool strips.

[0007] Based on the above scheme and as a preferred option, the density of the rock wool strips is greater than 70 kg / m3.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the length of the rock wool strip is less than the length of the rock wool layer.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the rock wool layer and the aluminum film layer are bonded together with phenolic resin.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the outer surface of the rock wool layer is provided with a groove for the rock wool strip to be inserted.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are: The industrial thermal insulation rock wool of this utility model adopts a rock wool strip structure with a certain thickness. The two ends of the metal wire are intertwined and located on the outside of the rock wool strip. When the intertwined iron wire is bent, the iron wire will stick to the rock wool strip, which can effectively prevent the ends of the iron wire from puncturing the aluminum film layer.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0016] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0017] This utility model discloses an industrial thermal insulation rock wool, including a rock wool layer 1, which is typically a felt structure made of rock wool material. In one embodiment, the density of the rock wool layer 1 is 30 kg / m³. 3An aluminum film layer 2, also known as aluminum foil, is provided on the outer side of the rock wool layer 1. Rock wool strips 3 are provided on the outer side of the aluminum film layer 2, and the density of the rock wool strips 3 is greater than that of the rock wool layer 1. The rock wool strips 3 do not completely cover the aluminum film layer 2 in the circumferential direction. In the specific application of the industrial thermal insulation rock wool of this utility model, the rock wool layer and the aluminum film layer cover the outside of the pipe, forming a tubular structure. From the cross-section, the rock wool strips 3 are only distributed locally in the circumferential direction, so the rock wool strips 3 are not distributed in the entire circumferential direction. The two ends of the metal wires used for circumferentially winding around the aluminum film layer 2 and the outer side of the rock wool are intertwined, and the position where the two ends of the metal wires intertwine is located on the outer side of the rock wool strips 3. In this utility model, the rock wool strips 3 have a density of 70-90 kg / m³. 3 The rock wool board is cut into strips with a thickness of 5cm and a width of 8cm. Since the rock wool strip 3 has a certain thickness, the two ends of the metal wire are intertwined on the outside of the rock wool strip 3. When the intertwined wires are bent, the wires will stick to the rock wool strip 3, which can effectively prevent the ends of the wires from puncturing the aluminum film layer 2.

[0018] In one embodiment, the length of the rock wool strip 3 is less than the length of the rock wool layer 1. In the description of this embodiment, the direction perpendicular to the plane of the drawing is defined as the length direction. Because the rock wool strip 3 is shorter, it can be installed only where wires need to be tied, which facilitates construction.

[0019] In this embodiment, the rock wool layer 1 and the aluminum film layer 2 are bonded together with phenolic resin. Because the rock wool layer 1 and the aluminum film layer 2 are bonded together, it is easy to wrap the industrial thermal insulation rock wool around the outside of the pipe, thus simplifying construction.

[0020] In this embodiment, a groove 4 is provided on the outer surface of the rock wool layer 1, into which the rock wool strips 3 are inserted. As shown in the figure, the rock wool layer 1 adopts a multi-layer rock wool felt structure, which has a first rock wool felt layer 5, a second rock wool felt layer 6, and a third rock wool felt layer 7. The second rock wool felt layer 6 and the third rock wool felt layer 7 are located above the first rock wool felt layer 5, and there is a gap between the second rock wool felt layer 6 and the third rock wool felt layer 7, thereby forming the groove 4. The second and third rock wool felts are both bonded or sewn to the first rock wool felt. In practical applications, since the groove 4 is used to insert the rock wool strips 3, the overall flatness is higher after covering the outside of the pipe.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
