Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an algae-proof sheet which is attached to a moist part such as a revetment, a bridge, or a footboard of a ship-side elevating ladder on which many people walk so as to prevent slipping and to provide an appropriate cushioning property.

[0002]

[Prior Art]

 Since concrete revetments on the coast, riverbanks, and lakeshores, or the Tsukihashi, which holds ships alongside the shore, are always exposed to seawater and river water and are moist, algae often form and adhere to the surface. A large amount of algae may adhere to the surface of objects immersed in seawater or river water other than seawalls and Tsukihashi, and moss may be generated just by being exposed to rainwater in places with poor sunlight. ..

When a person walks on a revetment or a bridge over which algae adheres, it is very dangerous because the algae on the surface makes the foot slippery. Conventionally, a special paint is applied to the surface of a concrete revetment and a bridge to prevent the generation of algae.

[0004]

[Problems to be solved by the device]

 Even if it is possible to temporarily prevent the generation of algae by applying a special paint to the surface of the concrete revetment and the bridge, the surface of the paint itself is smooth, so there is not much danger of pedestrians slipping. It doesn't change. Also, since this special paint is easily peeled off by the impact of human walking, it is rarely actually applied to the surface of concrete revetments and the bridge.

The present inventor has carried out various studies on the problem that the surface of revetments and bridges exposed to seawater or river water is slippery by algae, and as a result, by covering with a sheet of a specific composition, the algae in a wet place. We succeeded in preventing the occurrence of. Therefore, it is an object of the present invention to provide an algae-preventing sheet that has an anti-slip effect on a seawall, a bridge, etc. where many people walk. Another object of the present invention is to provide an algae-preventing sheet which has an appropriate cushioning property to facilitate walking when attached to a wet place.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the algae sheet 1 according to the present invention integrates a normal synthetic fiber 2 and a fiber 3 containing a copper component by needle punching (see FIG. 1). Usual synthetic fibers 2 are polyester, polypropylene, acrylic fiber, nylon fiber and the like. As the fiber 3 containing a copper component, synthetic fibers are subjected to copper plating by vapor deposition, copper ions are dispersed in the synthetic fibers to form a copper compound, synthetic fibers are mixed with copper fibers, and copper powder is added to the polymer. The fiber kneaded with may be used.

The algae control sheet 1 has cushioning properties by having a certain thickness, and a base fabric 4 such as a woven fabric may be interposed in the middle or lower side of the sheet for reinforcement. If the water resistant adhesive 5 is applied to the back surface of the algae-proof sheet 1, it can be directly attached to a wet place where algae are likely to be generated.

As shown in FIG. 2, the algae-preventing sheet of the present invention is attached around an object such as a cylinder 10 existing in a wet place where algae are likely to be generated, and prevents algae from adhering to the surroundings. be able to. Since this algae-proof sheet has cushioning properties, it protects the cylindrical body 10 from an external impact, and if the sheet is removable, it can be easily replaced and dried.

As shown in FIG. 3, the algae-preventing sheet of the present invention may be stationary at a wet place where algae are likely to be generated by fixing at least both ends thereof. If the algae control sheet can be removed by such measures, it can be easily replaced and dried.

[0010]

[Action]

 To test the inhibitory action of algae generation by copper, as the fiber 3 containing a copper component, a sheet piece A of copper fiber (trade name: Kapron) with a diameter of 30 μm, a copper plating fiber with a diameter of 13.5 μm (trade name) A sheet piece B of (Metax) and a sheet piece C of copper ion dispersed fiber (trade name: Sandalon) having a diameter of 22 μm are manufactured. The sheet piece A has a sample weight of 0.046 g and a copper fiber weight of 0.03%, the sheet piece B has 0.123 g and 0.018%, and the sheet piece C has 0.102 g and 0.015%.

Next, raw water containing algae (water from Kunyo Pond, Itami City) was taken in four beakers, and each of the beakers was placed with sheet pieces A, B, and C, and left outdoors with a beaker containing only raw water. To do. The amount of water in each beaker is 200 cm ³ , and when it reaches about 100 cm ³ by natural evaporation, distilled water is added to restore the volume to 200 cm ³ .

[0012] In the time-course observation, the beaker containing only raw water showed the generation of algae in about 1 week, and the beaker containing the sheet pieces A, B, and C finally showed the generation of a small amount of algae after 1 month. It ’s just done. After that, although there was little change due to unseasonable weather, algae outbreaks will progress rapidly from the 70th day as the weather improves.

The experiment period was 90 days, and in the appearance observation after the lapse of the predetermined period, the most algae were found in beakers containing only raw water, followed by beakers containing sheet pieces B, C, and A in the following order. Become. Finally, the water is evaporated and the dry weight of the generated algae is measured as follows. Beaker with Sheet A: 0.027g Beaker with Sheet B: 0.037g Beaker with Sheet C: 0.028g Beaker with raw water only: 0.060g

From the test results, it is clear that copper has an action of suppressing the generation of algae. In the normal sheet usage mode, the algae are generated much less than the test result because the sheet is generally in running water at a lower water temperature than in this test.

【Example】

The present invention will be described based on examples. FIG. 1 shows an algae control sheet 1 according to the present invention. 80% of green polyester fiber having an average fiber length of 76 mm at 70 denier and 20% of copper-plated fiber of polyester having an average fiber length of 64 mm at 15 denier (trade name: METAX, manufactured by Takase Senko) A card wrap with a weight of 400 g / m ² is used, and a polypropylene slit yarn plain weave 90 g / m ² base fabric 4 is placed underneath it, and the whole is integrated by needle punching. Get the material.

200 g / m ^{2 of} acrylic acid ester adhesive 5 is applied to the back surface of this felt material. The algae-preventing sheet 1 may be attached via an adhesive 5 to a concrete revetment, a bridge, a boardwalk, etc. where algae are likely to occur, and a new sheet may be attached if it is damaged or soiled.

In order to test again the action of suppressing the generation of algae by the algae control sheet 1, 1000 cm ³ of raw water containing algae (Kunyo Pond water in Itami City) was placed in 2 beakers, and the algae control sheet was placed in one beaker. Insert 10g of the slice cut from 1, and leave the other beaker with raw water for 3 months.

According to visual observation after the lapse of a predetermined period of time, the amount of algae generated was 2 in the beaker containing only 10 g of the raw water compared to 10 in the beaker containing the sheet slice. The generated algae are filtered, and the dry weight thereof is measured as follows. Beaker containing 10g of sheet section: 38mg Beaker of raw water only: 410mg

From this test result, it is apparent that the algae control sheet 1 has an action of suppressing the generation of algae. In the normal sheet usage mode, the algae generation is less than the test result because it is generally in the state of running water.

The algae-preventing sheet 1 is safe because it prevents algae from being generated on the surface of concrete revetments, bridges and promenades, and prevents slipping by algae when many people walk. Since the algae-proof sheet 1 is colored green, it is preferable for enhancing the aesthetic appearance, and in some cases, it can be used for confirming the sticking position.

If a release paper is attached to the back surface of this algae-proof sheet and cut to an appropriate size, it can be carried when fishing, etc., and immediately fixed at the site of use to fix the foot position at the fishing spot. Available. For example, if this algae-proof sheet is attached to a rocky area for rock fishing, it can be used to check the rock fishing position and fix the scaffold when regularly visiting the island.

This algae control sheet is also used as a cushioning material by utilizing its cushioning property, and in this case, the sheet may be considerably thickened. For example, if this algae sheet is attached to the berth slope of the yacht harbor, it will be a safety measure to prevent the yacht from slipping, and it will be effective for soft landing of the yacht. If this algae sheet is attached to the bottom surface and wall surface of the ferry boat's elevator opening / closing port, it will help prevent the wheels from slipping and reduce collisions with the wall when the vehicle is raised / lowered. If it is attached to the side of a ship such as a boat or the side wall of a concrete revetment, the impact when they contact each other can be mitigated.

Although the algae sheet 11 shown in FIG. 2 is made of the same felt material as described above, the back surface is not coated with an adhesive. The algae-preventing sheet 11 is formed into a tubular shape by stitching on both sides or chucks 12 and wound around the tubular body 10 that is immersed in seawater 13 or lake water for a long time to prevent algae from adhering to the periphery. ..

Examples of this type of cylindrical body 10 include measuring equipment such as water temperature and water surface and ship fittings. Since the algae sheet 11 has a cushioning property at the same time as preventing the adhesion of algae, it protects the cylinder 10 and prevents it from slipping when held by hand.

The algae-preventing sheet 11 can be easily exchanged and dried if it can be attached and detached with a chuck 12 or the like, and in the case of a measuring instrument, it can be removed or the attachment position can be shifted when checking the scale. If there is a possibility that the algae-preventing sheet 11 may be displaced when it is attached for a long period of time, it may be firmly fixed with a separate fastening member (not shown).

The algae-proof sheet 15 shown in FIG. 3 has both side ends sewn in a tubular shape, and no adhesive is applied to the back surface. The algae-proof sheet 15 is placed on a plate 17 having a large number of protrusions 16 on its surface, and then the fixing rods 19 are inserted into the cylindrical portions 18 on both sides of the plate 17, so that algae are likely to be generated in a wet place. Rest at. When the algae control sheet 15 is attached on the plate 17, the projections 16 on the plate surface bite into the sheet 15, so that the sheet 15 will not be displaced without using an adhesive.

The algae-preventing sheet 15 is attached to the surface of a concrete revetment, a bridge, a boardwalk or the like together with the plate 17 to prevent algae from being generated, and to prevent a large number of people from sliding with algae. The algae control sheet 15 can be removed only by pulling out the fixing rods 16 and 16, and the sheet can be easily replaced and dried.

The algae-proof sheet 20 shown in FIG. 4 is sewn into a tubular shape as a whole, and no adhesive is applied to the back surface. The algae-proof sheet 20 can be stopped in a wet place where algae are likely to be generated, simply by fitting it to a plate 22 having a large number of protrusions 21 on its surface. When the algae-proof sheet 20 is fitted to the plate 17, the projections 16 on the plate surface bite into the sheet 15 to prevent the sheet from slipping. The algae control sheet 20 can be removed only by pulling it out from the plate 22, and it is easy to replace and dry the sheet.

When the algae control sheet 15 or 20 is used together with the plate as a footboard of a ship-side elevating ladder, it has an appropriate cushioning property so that even an elderly person or a child can easily ascend and descend from the ship. The algae control sheet 15 or 20 can be used as a scaffolding board at a construction site during the rainy season together with a plate, and can also be used as an emergency staircase in a building exposed to rain and an entrance / exit of a building.
