Description

Technical Field

[0001] The present invention relates to a peeling method for easily peeling off films one by one from the uppermost layer on a mold peeling film of a film group formed by stacking films. Background Art

[0002] For molds used in construction sites, a coating agent has been proposed to protect the surface. In such a case, the mold unit price is increased due to the need to form a coating, and the performance of the mold is reduced when the coating is damaged.

[0003] In order to solve the above problems, a solution of sticking a protective film on the mold surface has been proposed. However, since the protective film is formed in a single layer, its usable period is short and needs to be replaced frequently, which makes it inconvenient to reuse the mold.

[0004] In order to solve the above problems, mold release films have been proposed. The mold release film is a film group formed by laminating films, and after being attached to a mold, if the film exposed on the top layer is damaged during use, the damaged films can be peeled off one by one for use. Summary of the invention

[0005] Technical issues to be solved

[0006] In a state where a mold peeling film formed by a film group composed of stacked films is pasted on a mold, when a damaged film needs to be torn off, a method is used in which a film to be torn off is held by hand and then torn off. However, the stacked films are in a state of being bonded by an adhesive with strong bonding force, and no gap is formed between the stacked films, so they cannot be easily torn off one by one. Therefore, the present invention provides a method for easily tearing off a damaged film in a state where the mold peeling film is pasted on a mold.

[0007] Solutions to technical problems

[0008] In order to achieve the above-mentioned purpose, the present invention provides a method of being equipped with a peeling tool with an edge formed at the end, which can make the top layer of the film be lifted up by simply pressing the edge against the edge of the film group and pushing it, and then tearing it off by holding the lifted position with hands and pulling it.

[0009] Effects of the Invention

[0010] According to the present invention, the damaged film can be easily torn off from the mold release film pasted on the mold. As a result, it can contribute to pasting the mold release film on the mold and facilitating its use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In one aspect of the present invention, there is provided a method for peeling a film from a mold release film, which includes preparing a release tool having a peeling end formed with an edge on one side, and only by tilting the release tool at a certain angle and abutting the edge formed on the peeling end against the edge of the film set and then pushing it toward the center of the film set, a holding position can be formed where the film overlapping on the outermost layer is pushed and lifted at the edge of the film set, and then by grasping the holding position, the film laminated on the outermost layer can be torn off from the film set.

[0023] Next, the present invention will be described in detail with reference to Figures 1 to 8 is an exploded view of the release film according to the present invention, and

[0024] Figure 1 is an exemplary view of the state where the release film according to the present invention is pasted on the mold. Figure 2

[0025]

[0025] As shown in the figure, the mold release film according to the present invention includes a film group 100 formed by laminating film layers 120. The film 120 is made of synthetic resin material and is cut into a certain area. A material that can be easily bent and easily separated from concrete while having a certain strength can be selected. The shape of the film 120 as described above can be made into a quadrilateral or a rectangle according to the shape of the formwork used at the construction site, but it is not limited thereto.

[0026] The film 120 is laminated in multiple layers. When laminating the film 120, an adhesive can be used. The adhesive has the property of being able to be re-separated after bonding. Thus, the film 120 can be laminated by coating it on the surface of the film 120, and individual films 120 can be torn off from the film group 100 when needed.

[0027] The adhesive can be coated on the bottom surface of the upper-layer film 120 among the laminated films 120. In the above situation, the adhesive does not remain on the surface of the lower-layer film 120 exposed after tearing off the upper-layer film 120, thereby preventing foreign substances from adhering to the surface of the film group 100.

[0028] The film group 100 as described above is pasted onto the mold surface. It is used by pasting it onto the mold surface through an adhesive or a bonding agent. By pasting the film group 100 onto the mold, not only can the mold surface be protected, but also according to the material characteristics of the film 120, the mold can be easily separated from the concrete when the mold is separated after the concrete curing is completed.

[0029] In addition, the mold is installed in a state where the film group 100 is pasted onto the mold surface. Next, after pouring the concrete and curing it, the mold is separated and reused. In the above process, the surface of the film 120 in the film group 100 that comes into contact with the concrete may be contaminated or damaged. The contaminated or damaged film 120 as described above needs to be torn off from the film group 100. The film 120 is laminated in multiple layers to form the film group 100. Only the damaged film 120 needs to be removed to maintain the performance of the film group 100. Therefore, during the process of reusing the mold, the mold can be repeatedly reused by sequentially removing the contaminated or damaged films.

[0030] Figure 3 And Figure 4 is an exemplary diagram illustrating an example of the release tool used in the present invention, and Figures 5 to 8 is an exemplary diagram illustrating the process of peeling off the film using the release tool according to the present invention.

[0031] In the present invention, the release tool 300 is used to tear off the film 120 from the film group 100 pasted onto the mold 200.

[0032] The peeling tool 300 has a peeling end 320 with edges formed on one side. As needed, the other side can adopt a structure with a handle 360 formed thereon. In the case where the handle 360 is formed, the part other than the handle 360 can be configured in an overall flat shape, but as long as it constitutes the structure of the peeling end 320 with edges, it is not particularly limited.

[0033] The edges formed on the peeling end 320 are formed by the joining of two surfaces, and the angle formed by the two surfaces can be formed at an angle of approximately 45 to 100 degrees. Preferably, it can be formed at an angle of 90 degrees or close to 90 degrees.

[0034] When it is necessary to separate the film 120 from the film stack 100, hold the handle 360 of the peeling tool 300 by hand and abut the edges formed on the peeling end 320 against the surface of the film stack 100 at the edge of the film stack 100 ( Figure 5 ). The position where the peeling tool 300 abuts is preferably near the edge of the film stack 100, but it is not limited thereto.

[0035] The peeling tool 300 will abut against the surface of the film stack 100 in a state of being inclined at a certain angle. Thereby, the edges formed on the peeling end 320 will come into contact in a direction of being embedded and overlapping the uppermost film 120.

[0036] In the state where the edges formed on the peeling end 320 are abutted against the appropriate position as described above, push the peeling tool 300 toward the center of the film stack 100. Thereby, the edges formed on the peeling end 320 will be embedded into the surface of the uppermost film 120 to a certain depth ( Figure 6 ), thereby pushing the uppermost film 120 that overlaps. As a result, the uppermost film 120 that overlaps will move and warp relative to the film 120 that overlaps below it ( Figure 7 and Figure 8 ). The warped part as described above is the holding position.

[0037] Among them, when the angle of the edges formed on the peeling end 320 is too small, a structure similar to a blade will be formed. Therefore, there will be a problem that the peeling end 320 is embedded too deeply into the uppermost film 120 that overlaps. As a result, the film 120 formed on the uppermost layer will not move but be cut, and thus the holding position cannot be formed smoothly. On the contrary, when the angle of the edges formed on the peeling end 320 is too large, the edges formed on the peeling end 320 will be difficult to be embedded into the surface of the uppermost film 120 to an appropriate depth. Therefore, it will be difficult to ensure an appropriate frictional force with the surface of the film 120, and thus the uppermost film 120 that overlaps cannot be pushed. As a result, the holding position cannot be formed smoothly.

[0038] After forming the gripping position in the manner described above, grasp the gripping position by hand and pull. By doing so, the film 120 that overlaps to the top layer on the film set 100 can be torn off and peeled from the film 120 that overlaps to its lower layer. The films 120 can be torn off one by one from the film set 100.

[0039] Through the process described above, the damaged film 120 can be easily removed from the film set 100 pasted on the mold 200, so that the mold 200 can be reused smoothly.
