Description

The present invention relates to a sputter adhesion preventing material having non-adhesiveness to sputtering and a spatter adhesion preventing apex using the same.

Conventionally, in the pre-furnace work for operating the tap opening / closing machine of the refuse melting furnace, a heat-resistant apron is further worn on the fire-resistant clothing as a protective device against scattered spatter. Here, as a material for the apron, ceramic powder is applied to the surface of a glass fiber heat-resistant cloth material or a cloth material such as leather, chemical fiber, and cotton using a heat-resistant adhesive such as silicone rubber. A composite cloth material having a ceramic layer fixedly formed (see, for example, Patent Document 1) can be used.

JP-A-10-166153

However, when using an apron made of a glass fiber heat-resistant cloth material, the apex itself is lower in temperature than the spattering temperature of the spatter. There is a problem. In addition, when using an apron using a composite cloth material with a ceramic adhesive layer formed, if the spatter scattered comes into contact with the adhesive part constituting the ceramic layer, the heat resistance temperature of the adhesive itself is scattered. Since the temperature is lower than the sputtering temperature, the adhesive easily changes in quality, resulting in a problem that the holding power of the ceramic powder is reduced and the ceramic layer is partially dropped. For this reason, if the apron is used continuously, there is a problem that the ceramic layer is gradually lost and the heat resistance of the apex gradually decreases.
Therefore, an apron using a silica fiber heat-resistant cloth material having heat resistance that is not damaged at the temperature of the spattering scattered is used. However, since the silica fiber is not damaged even if it comes into contact with the sputter, the silica fiber is entangled with the spatter that has been scattered, and the sputter that has come into contact is firmly restrained by the silica fiber. For this reason, the problem that spatter easily adheres to the apex has arisen.

The present invention has been made in view of such circumstances, and an object thereof is to provide a spatter adhesion preventing material having heat resistance and spatter non-adhesion and a highly durable spatter adhesion prevention apex using the same.

Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.

FIG. 3 is a plan view of a scale-like laminate according to a modification of the spatter adhesion preventing material, and FIG. 4A is a scale shape according to another modification of the spatter adhesion preventing material. (B) is a cross-sectional view taken along the line PP of (A), FIG. 5 is a partial side cross-sectional view of the spatter adhesion preventing material according to the third embodiment of the present invention, and FIG. 6 (A). FIGS. 7A and 7B are partial side cross-sectional views of a first modification and a second modification of the spatter adhesion preventing material, respectively, and FIG. 7 is an explanatory diagram of a spatter adhesion prevention apron according to the fourth embodiment of the present invention. FIG. 8 is an explanatory view of a modified example of the spatter adhesion preventing apron.

As shown in FIG. 1, a spatter adhesion preventing material 10 according to the first embodiment of the present invention includes a base cloth 11 made of silica fiber and a metal that is a spatter adhesion preventive layer formed on the surface of the base cloth 11. An aluminum layer 12 which is an example of the layer is included. Here, the aluminum layer 12 is formed on the surface of the base fabric 11 by, for example, spraying aluminum. As the aluminum spraying method, for example, a molten droplet is formed by continuously supplying an aluminum wire into a combustion flame of a mixed gas of oxygen and acetylene to form fine droplets. It is possible to use hot wire flame spraying that is accelerated by compressed air flow and collides with the surface of the base fabric 11 to be deposited. The aluminum droplets that collide with the base fabric 11 are entangled with the silica fibers 13 constituting the base fabric 11 and solidified to form minute granular deposits 14 and adhere to the surface of the base fabric 11. And while the deposit 14 continues on the surface of the base fabric 11, the thickness increases and the aluminum layer 12 is formed. As a result, the surface of the base fabric 11 is covered with the aluminum layer 12, and it is possible to prevent the scattered sputter and the silica fiber 13 from coming into direct contact.

Here, in the surface layer portion of the aluminum layer 12, aluminum is oxidized during the formation of the aluminum layer 12, and an aluminum oxide film is generated. Therefore, the aluminum oxide film inhibits the contact between the sputter and the aluminum, and aluminum It is understood that spatter adherence to layer 12 is prevented. For this reason, the sputter that has come into contact with the aluminum layer 12 immediately drops off from the aluminum layer 12, and heat transfer from the sputter to the aluminum layer 12 is interrupted. For this reason, it is understood that thermal damage due to sputtering of the aluminum layer 12 is suppressed.
In addition, the thickness of the aluminum layer 12 formed on the base fabric 11 is 0.05 mm or more, preferably 0.1 mm or more, 0.5 mm or less, preferably 0.2 mm or less. If the aluminum layer 12 is less than 0.05 mm, the base fabric 11 is easily exposed when wrinkles occur on the surface of the aluminum layer 12, which is not preferable. Further, when the thickness exceeds 0.5 mm, it becomes difficult for the aluminum layer 12 to deform following the deformation of the base cloth 11. For example, when the base cloth 11 is largely bent, the interface between the base cloth 11 and the aluminum layer 12 is difficult. The possibility that the aluminum layer 12 peels off due to cracking is increased, which is not preferable.

The aluminum layer can also be formed by depositing aluminum on the surface of the silica fiber base fabric 11, or by electroless plating of aluminum on the surface of the silica fiber base fabric 11 or aluminum on the surface of the base fabric 11. It can also be formed by forming a sprayed film or a vapor deposition film uniformly to impart conductivity and then performing electroplating.
Furthermore, a silver layer or a brass layer can be formed as a spatter adhesion preventing layer instead of the aluminum layer. Here, the formation of the silver layer or the brass layer can be performed by any of vapor deposition, thermal spraying, and electroless plating on the surface of the base fabric 11, and further, the surface of the base fabric 11 is thermally sprayed with silver or brass. It can also be performed by electroplating after each film is formed to impart conductivity. An oxide film formed by oxidation of silver is formed on the surface layer portion of the silver layer, and an oxide film formed by oxidation of zinc and copper constituting the brass is formed on the surface layer portion of the brass layer. It is understood that contact between silver and brass is hindered and spatter adherence to the silver layer or brass layer is prevented. For this reason, the sputter that comes into contact with the silver layer or the brass layer immediately drops off from the silver layer or the brass layer, the heat transfer from the sputter to the silver layer or the brass layer is cut off, and thermal damage due to the sputter of the silver layer or the brass layer is caused. It is understood that it is suppressed.

As shown in FIG. 2A, the spatter adhesion preventing material 15 according to the second embodiment of the present invention is not adhered to the surface of the silica fiber base cloth 11 and the base cloth 11 against the spatter. It has a scale-like laminate 17 formed by attaching an aluminum plate 16, which is an example of a metal plate having the property, to a scale. The scaly laminate 17 has a first aluminum plate row 18 attached side by side in the horizontal direction on the base fabric 11 with the edges on both sides of each aluminum plate 16 being in close contact, and the first aluminum plate row 18 sideways. The second aluminum plate row 19 formed on the base fabric 11 is shifted in the direction by a distance corresponding to half the width of the aluminum plate 16 and the lower side overlaps the upper side of the first aluminum plate row 18. Have. Note that the second aluminum plate member row 19 is shifted by a distance corresponding to half the width of the aluminum plate member 16 in the lateral direction so that the lower side overlaps the upper side of the second aluminum plate row 19. One aluminum plate array 18 is formed on the base fabric 11. Thereby, the surface of the base fabric 11 can be covered with the first and second aluminum plate member rows 18 and 19. Here, the 1st and 2nd aluminum board | plate material row | line | columns 18 and 19 straddle the boundary part of the adjacent aluminum board | plate material 16, and penetrate each aluminum board | plate material 16, for example, the base fabric 11 via the string 20 made from a silica fiber. It is formed by sewing.

In addition, the aluminum plate 16 has a rectangular shape on one side in a plan view and an arc shape on the other side. Further, as shown in FIG. , Curved upward. By adopting such a shape, the aluminum plate 16 can be easily sewn to the base cloth 11 by passing the string 20 through one side of the aluminum plate 16, and the first and second aluminum plate rows 18 and 19 can be prevented from interfering with the aluminum plate material 16 constituting the first aluminum plate material row 18 and the aluminum plate material 16 constituting the second aluminum plate material row 19. It is possible to prevent objects from being caught on the other side. Moreover, the thickness of the aluminum plate material 16 can be 0.5-2 mm, for example. If the thickness of the aluminum plate material 16 is less than 0.5 mm, the aluminum plate material 16 is easily deformed and it is difficult to maintain the shape, which is not preferable. If the thickness of the aluminum plate exceeds 2 mm, the scale-like laminate 17 becomes heavy and the weight of the spatter adhesion preventing material 15 becomes large, which is not preferable.

By configuring the scaly laminate 17 as described above, in the first aluminum plate member row 18 (second aluminum plate member row 19), the string 20 exposed at the boundary portion of each aluminum plate member 16 can be The aluminum plate member row 18 (second aluminum plate member row 19) can be covered with the second aluminum plate member row 19 (first aluminum plate member row 18) that overlaps the upper side. This prevents the spatter that is scattered from coming into contact with the string 20 and prevents the object from being caught by the string 20.

Furthermore, when the base fabric 11 is deformed by forming the scaly laminate 17 with the first and second aluminum plate material rows 18 and 19, the scaly laminate 17 is at least a unit of length of the aluminum plate 16 in the vertical direction. In the lateral direction, the aluminum sheet 16 can be deformed in units of the lateral width, and exposure of the base fabric 11 can be suppressed when the scale-like laminate 17 is deformed. For this reason, it can prevent that the spatter which scattered has contacted the base fabric 11. FIG.
Further, since an aluminum oxide film is formed on the surface layer portion of the aluminum plate material 16, it is considered that the contact between the sputter and the aluminum is inhibited by this aluminum oxide film and the adhesion of the sputter to the aluminum plate material 16 is prevented. . For this reason, it is understood that the sputter that has come into contact with the aluminum plate 16 is immediately dropped from the aluminum plate 16, the heat transfer from the sputter to the aluminum plate 16 is cut off, and thermal damage due to the sputtering of the aluminum plate 16 is suppressed.

Here, as shown in FIG. 3, a scale-like laminate 23 in which the overlapping width of the first aluminum plate member row 21 and the second aluminum plate member row 22 is increased can also be formed. In this case, since the aluminum plate member 24 constituting the second aluminum plate member row 22 exists below the boundary portion between the adjacent aluminum plate members 24 in the first aluminum plate member row 21, the scale-like laminate 23 is greatly deformed. Even if the boundary between the adjacent aluminum plate members 24 is separated, the exposure of the base cloth 11 can be prevented, and the scattered spatter can be reliably prevented from coming into contact with the base cloth 11.
The aluminum plate may be rectangular or square when viewed from above, or flat when viewed from the side, refracted upward at the center, and linearly raised at the other side. Further, in the present embodiment, the aluminum plate materials are all made substantially the same size, but a plurality of types of aluminum plate materials having different sizes can be used to form the scale-like laminate. Thereby, the deformability of the scaly laminate can be adjusted, and the scaly laminate can be deformed according to the deformation of the base fabric.

Further, as shown in FIG. 4, a cover portion 26 is formed on one edge portion on both sides of the aluminum plate material 25, and the cover portion 26 covers the other edge portion of the adjacent aluminum plate material 25. The aluminum plate material row 27 and the second aluminum plate material row 28 may be formed into a scale-like laminate 23a.
By adopting such a configuration, even when the overlap width between the first aluminum plate member row 27 and the second aluminum plate member row 28 is small, the first and second aluminum plate member rows 27 and 28 are greatly deformed. Even if the boundary between the adjacent aluminum plate members 25 is separated, the exposure of the base cloth 11 can be prevented, and the scattered spatter can be reliably prevented from coming into contact with the base cloth 11.

Further, any one of a silver plating plate material, a brass plate material, and a carbon plate material (an example of a non-metal plate material) can be used instead of the aluminum plate material. When using a silver-plated plate material, there is an oxide film formed by oxidation of silver on the surface layer portion. When using a brass plate material, the surface layer portion is formed by oxidation of zinc and copper. It is understood that there is an oxide film, and this oxide film inhibits the contact between the sputter and silver or brass and prevents the spatter from adhering to the silver-plated plate material or the brass plate material. When the carbon plate material is used, the adhesion of the spatter to the carbon material is very poor, so that the spatter adherence to the carbon plate material is prevented. In this way, the spatter that comes into contact with the silver plating plate, brass plate, or carbon plate is immediately removed, and heat transfer from the sputter to the silver plating plate, brass plate, or carbon plate is cut off, and the silver plating plate, brass plate It is understood that thermal damage due to sputtering of the carbon plate material is suppressed.

As shown in FIG. 5, the spatter adhesion preventing material 29 according to the third embodiment of the present invention includes a base fabric 11 made of silica fiber and a heat-resistant adhesive having flexibility on the surface of the base fabric 11. An aluminum thin plate layer 31 having flexibility and attached via an adhesive layer 30 of a silicone-based adhesive as an example.
As a result, the surface of the base fabric 11 is covered with the aluminum thin plate layer 31, and the scattered spatter and the silica fiber 13 can be prevented from coming into direct contact. In addition, since an aluminum oxide film is formed on the surface layer portion of the aluminum thin plate layer 31, contact between the sputter and the aluminum is inhibited by the aluminum oxide film, and adhesion of the sputter to the aluminum thin plate layer 31 is prevented. It is understood. As a result, it is understood that the sputter that has come into contact with the aluminum thin plate layer 31 is immediately dropped, heat transfer from the sputter to the aluminum thin plate layer 31 is cut off, and thermal damage due to sputtering of the aluminum thin plate layer 31 is suppressed.

Here, the thickness of the aluminum thin plate layer 31 is 0.05 mm or more, preferably 0.1 mm or more and 0.5 mm or less, preferably 0.2 mm or less. If the aluminum sheet layer 31 is less than 0.05 mm, the base fabric 11 is easily exposed when wrinkles occur on the surface of the aluminum sheet layer 31, which is not preferable. Further, when the thickness exceeds 0.5 mm, it becomes difficult for the aluminum thin plate layer 30 to deform following the deformation of the base fabric 11. For example, when the base fabric 11 is largely bent, the adhesive layer 30 and the aluminum thin plate layer 31. The possibility that the aluminum thin plate layer 31 is peeled off due to a crack at the interface is increased.

Moreover, as shown in FIG. 6 (A), even if the aluminum thin plate layer 31 is attached to the base fabric 11 using, for example, aluminum split pins 32, the aluminum thin plate layer 31 is shown in FIG. 6 (B). May be attached to the base fabric 11 using, for example, an aluminum rivet 33. By attaching the aluminum thin plate layer 31 to the base cloth 11 without using an adhesive layer, the aluminum thin plate layer 31 does not peel from the base cloth 11 even if the aluminum thin plate layer 31 is greatly deformed together with the base cloth 11. Can do.
Further, instead of the aluminum thin plate layer 31, a silver thin plate layer or a brass thin plate layer having a thickness of 0.05 mm or more, preferably 0.1 mm or more and 0.5 mm or less, preferably 0.2 mm or less is attached to the base fabric 11. May be. Further, instead of the aluminum thin plate layer 31, a carbon fiber cloth material is used as a base cloth through a heat-resistant adhesive layer having a flexibility such as a silicone adhesive, or an aluminum cotter pin or aluminum. You may attach using a rivet.

As shown in FIG. 7, the spatter adhesion preventing front 34 according to the fourth embodiment of the present invention includes a front part 35 mainly composed of the spatter adhesion preventing material 10 according to the first embodiment of the present invention, A hook string 36 is sewn on both sides of the upper end portion of the front hook portion 35. With this configuration, the spatter adhesion preventing front 34 can be hung on the neck via the hanging strap 36 by passing the head through the opening 37 surrounded by the upper end of the front hanging portion 35 and the hanging strap 36. it can.
As a result, the range from the chest to the feet of the fire clothes can be covered with the spatter adhesion prevention apex 34. For example, spatter scattered during the operation of the tap opening / closing machine of the refuse melting furnace is prevented from directly adhering to the fire clothes. it can. And since the aluminum layer 12 is supported by the silica fiber base fabric 11, it has sufficient heat resistance. For this reason, the spatter adhesion preventing apex 34 can achieve both the heat resistance and the difficult adhesion of the sputtering, and the durability can be improved.

Further, as shown in FIG. 8, as the spatter adhesion preventing front 38, a front hook 39 is composed of a breast pad 40 and a waist pad 41, and fasteners for fixing both ends of the hook string 42 on both sides of the upper end part of the breast pad 40. 43, the attachment holes 44 are formed on both sides of the upper end portion of the waist pad 41, and one end portion of the waist strap 45 is inserted into the attachment hole 44 from the front side to be sewn to the back surface side of the waist pad 41. You can also. Here, as the fastener 43, a hook-and-loop fastener, a snap button, or the like can be used.
With such a configuration, both ends of the strap 42 can be fixed to both sides of the upper end of the breast pad 40 via the fasteners 43, and an opening surrounded by the upper end of the breast pad 40 and the hook 42. By passing the head through 46, the spatter adhesion preventing front 38 can be hung on the neck via the hanging strap 42. Furthermore, the waist rest 41 can be fixed around the waist by tying the other side of each waist strap 45.
