Description
本発明は、防水塗料を塗布することにより壁面に防水塗膜を形成する防水塗装方法に関する。 The present invention relates to a waterproof coating method for forming a waterproof coating on a wall surface by applying a waterproof paint.
防水性が求められる建造物では、壁面や床面等に防水塗装が施されることがある。このとき、所望の防水性が確保できたかを確認する方法として、防水塗膜の膜厚を計測する方法が有効である。防水塗膜の膜厚を管理する方法として、例えば特許文献１に防水施工方法が開示されている。 In buildings where waterproofness is required, waterproof coating may be applied to walls, floors, and the like. At this time, a method of measuring the film thickness of the waterproof coating is effective as a method for confirming whether the desired waterproof property has been secured. As a method for managing the film thickness of the waterproof coating film, for example, Patent Document 1 discloses a waterproof construction method.
特許文献１の防水施工方法では、塗膜形成面に視覚的に識別可能なマーキングを設け、液状防水材を塗布することによってマーキングを隠蔽可能としている。特許文献１によれば、液状防水材の防水塗膜によってマーキングが隠蔽されることにより、目的の膜厚が形成されたことを確認可能であるとしている。 In the waterproof construction method of Patent Document 1, a visually identifiable marking is provided on the coating film forming surface, and the marking can be concealed by applying a liquid waterproof material. According to Patent Document 1, it is possible to confirm that the target film thickness has been formed by hiding the marking with the waterproof coating film of the liquid waterproof material.
しかしながら、特許文献１の防水施工方法では、防水塗膜によってマーキングが隠蔽されていることを目視判断によって確認する。このため、特許文献１の方法であると、定性的な確認はできるものの、定量的な膜厚結果を確認できるわけではない。したがって、特許文献１の方法は、防水塗装の作業時の目安として用いるには有効であると考えられるが、防水塗膜の膜厚を厳密に管理する必要がある現場においては有用ではない。 However, in the waterproof construction method of Patent Document 1, it is confirmed by visual judgment that the marking is concealed by the waterproof coating film. For this reason, although it can qualitatively confirm by the method of patent document 1, it cannot necessarily confirm a quantitative film thickness result. Therefore, although it is thought that the method of patent document 1 is effective for using it as a standard at the time of the work of waterproof painting, it is not useful in the field where it is necessary to manage the film thickness of a waterproof paint film strictly.
防水塗膜の膜厚を定量的に確認する方法としては、渦電流式膜厚計を用いることが考えられる（例えば特許文献２）。特許文献２では、鉄以外の金属またはステンレス製のマーカーを床に貼り付けた後、その上にワックス、塗料等を塗布し、マーカー上の皮膜の膜厚を渦電流式膜厚計で計測している。 As a method for quantitatively confirming the film thickness of the waterproof coating, it is conceivable to use an eddy current film thickness meter (for example, Patent Document 2). In Patent Document 2, a marker made of a metal other than iron or stainless steel is attached to the floor, and then wax, paint or the like is applied thereon, and the film thickness of the film on the marker is measured with an eddy current film thickness meter. ing.
特許文献２のようにワックスや塗料を塗布する対象が床（床面）である場合、床は水平面であるため、ワックスや塗料を比較的均一に塗布しやすい。したがって、床に形成された塗膜の膜厚もほぼ均一になり、数か所のマーカーにおいて膜厚を測定すれば、床のほぼ全体の膜厚を確認することが可能である。これに対し、塗布する対象が壁（壁面）である場合、壁は垂直面である。このため、特に上下方向において塗布量に差が生じやすく、塗膜の膜厚を均一にすることが難しい。また作業員の熟練度による膜厚の差も生じやすい。このため、壁面の上下方向で塗膜の膜厚を詳細に確認することが可能な方法の開発が望まれていた。 When the object to which the wax or paint is applied as in Patent Document 2 is a floor (floor surface), the floor is a horizontal surface, and therefore it is easy to apply the wax and paint relatively uniformly. Therefore, the film thickness of the coating film formed on the floor becomes almost uniform, and if the film thickness is measured with several markers, it is possible to confirm the film thickness of almost the entire floor. On the other hand, when the object to be applied is a wall (wall surface), the wall is a vertical surface. For this reason, a difference in the coating amount tends to occur particularly in the vertical direction, and it is difficult to make the film thickness uniform. Also, a difference in film thickness due to the skill level of the worker is likely to occur. For this reason, development of the method which can confirm the film thickness of a coating film in the up-down direction of a wall surface in detail was desired.
本発明は、このような課題に鑑み、壁面に形成された塗膜の膜厚を、渦電流式膜厚計を用いて上下方向で詳細に確認することが可能な防水塗装方法を提供することを目的としている。 In view of such problems, the present invention provides a waterproof coating method capable of confirming in detail the film thickness of a coating film formed on a wall surface in the vertical direction using an eddy current film thickness meter. It is an object.
上記課題を解決するために、本発明にかかる防水塗装方法の代表的な構成は、壁面に左右方向で所定間隔ごとに上下方向に延びる導電性テープを貼着し、壁面に防水塗料を塗布することにより防水塗膜を形成することを特徴とする。 In order to solve the above problems, a typical configuration of the waterproof coating method according to the present invention is to apply a waterproof paint to a wall surface by sticking a conductive tape extending in the vertical direction at predetermined intervals in the left-right direction on the wall surface. Thus, a waterproof coating film is formed.
上記構成では、上下方向に延びる導電性テープを壁面に貼着した後に防水塗膜を形成する。これにより、導電性テープ上に形成された防水塗膜の膜厚を、上下方向の任意の位置で確認することができる。したがって、膜厚が薄い箇所に更に追加で防水塗料を塗布することにより、壁面全体において防水塗膜の膜厚が均一化され、防水性能を高めることが可能となる。 In the said structure, after sticking the electrically conductive tape extended in an up-down direction to a wall surface, a waterproof coating film is formed. Thereby, the film thickness of the waterproof coating film formed on the conductive tape can be confirmed at an arbitrary position in the vertical direction. Therefore, by additionally applying the waterproof paint to the thin film thickness, the thickness of the waterproof coating film is made uniform over the entire wall surface, and the waterproof performance can be improved.
上記導電性テープを貼着した後に壁面にプライマーを塗布し、プライマーが乾燥した後に壁面に防水塗料を塗布するとよい。かかる構成のように防水塗料を塗布する前にプライマーを塗布することにより、導電性テープの伸縮力と防水材の伸縮力の相違による引っ張り力の緩和と、導電性テープの厚みによる凹凸を平滑にすることができる。 A primer may be applied to the wall surface after the conductive tape is attached, and a waterproof paint may be applied to the wall surface after the primer has dried. By applying the primer before applying the waterproof paint as in this configuration, the tensile force due to the difference between the expansion force of the conductive tape and the expansion force of the waterproof material is alleviated and the unevenness due to the thickness of the conductive tape is smoothed. can do.
ここで、導電性テープを貼着する前にプライマーを塗布すると、壁面に形成された防水皮膜において導電性テープの縁の近傍において欠損が発生してしまうことがわかった。これに対し、導電性テープを貼着した後にプライマーを塗布することにより、欠損の発生を抑制することが可能となる。また導電性テープを貼着した後に壁面にプライマーを塗布することにより、導電性テープ上にもプライマーが塗布される。 Here, it was found that if a primer was applied before the conductive tape was adhered, a defect occurred in the vicinity of the edge of the conductive tape in the waterproof coating formed on the wall surface. On the other hand, it becomes possible to suppress generation | occurrence | production of a defect | deletion by apply | coating a primer after sticking a conductive tape. Moreover, a primer is apply | coated also on a conductive tape by apply | coating a primer to a wall surface after sticking a conductive tape.
当該防水塗装方法では、渦電流式膜厚計を用いて導電性テープ上の防水塗膜の膜厚を測定するとよい。これにより、防水塗膜の膜厚を定量的に確認することが可能となる。 In the waterproof coating method, the film thickness of the waterproof coating on the conductive tape may be measured using an eddy current film thickness meter. Thereby, it becomes possible to confirm the film thickness of a waterproof coating film quantitatively.
本発明によれば、壁面に形成された塗膜の膜厚を、渦電流式膜厚計を用いて上下方向で詳細に確認することが可能な防水塗装方法を提供することが可能となる。 ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the waterproof coating method which can confirm the film thickness of the coating film formed in the wall surface in detail up and down using an eddy current type film thickness meter.
以下に添付図面を参照しながら、本発明の好適な実施形態について詳細に説明する。かかる実施形態に示す寸法、材料、その他具体的な数値などは、発明の理解を容易とするための例示にすぎず、特に断る場合を除き、本発明を限定するものではない。なお、本明細書及び図面において、実質的に同一の機能、構成を有する要素については、同一の符号を付することにより重複説明を省略し、また本発明に直接関係のない要素は図示を省略する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.
図１は、本実施形態にかかる防水塗装方法を説明する図である。図２は、図１の各断面図である。図１（ａ）および図２（ａ）に示すように、本実施形態の防水塗装方法では、まず壁面１０２に左右方向で所定間隔ごとに上下方向に延びる導電性テープ１１０を貼着する。導電性テープ１１０としては、例えばアルミシートがラミネートされたテープを例示することができる。ただし、これに限定するものではなく、渦電流によって塗膜の膜厚を計測することが可能であれば、他の導電性テープを用いることも可能である。 FIG. 1 is a diagram for explaining a waterproof coating method according to the present embodiment. FIG. 2 is a cross-sectional view of FIG. As shown in FIGS. 1 (a) and 2 (a), in the waterproof coating method of the present embodiment, first, a conductive tape 110 extending in the vertical direction is attached to the wall surface 102 at predetermined intervals in the horizontal direction. As the conductive tape 110, for example, a tape laminated with an aluminum sheet can be exemplified. However, the present invention is not limited to this, and other conductive tapes can be used as long as the film thickness of the coating film can be measured by eddy current.
導電性テープ１１０を貼着したら、図１（ｂ）および図２（ｂ）に示すように、壁面１０２にプライマー１２０を塗布する。その後、プライマー１２０が乾燥したら、図１（ｃ）および図２（ｃ）に示すように、壁面１０２に防水塗料を塗布することにより、壁面１０２に防水塗膜１３０が形成される。このとき、プライマーや防水塗料は、図１（ｂ）や図１（ｃ）の矢印に示すように、左右方向にジグザグに壁面１０２に吹きつけられながら上下方向にわたって塗布される。防水塗料としては、例えばウレタン防水塗料を例示することができるが、これに限定するものではなく、他の防水塗料を用いてもよい。 When the conductive tape 110 is attached, the primer 120 is applied to the wall surface 102 as shown in FIGS. 1 (b) and 2 (b). Thereafter, when the primer 120 is dried, a waterproof paint 130 is formed on the wall surface 102 by applying a waterproof paint to the wall surface 102 as shown in FIGS. 1 (c) and 2 (c). At this time, as shown by the arrows in FIGS. 1B and 1C, the primer and the waterproof paint are applied in the vertical direction while being sprayed on the wall surface 102 in a zigzag manner in the horizontal direction. Examples of the waterproof paint include urethane waterproof paint, but are not limited to this, and other waterproof paint may be used.
上記構成によれば、導電性テープ１１０上に防水塗膜１３０が形成されることで、渦電流式膜厚計を用いて防水塗膜１３０の膜厚を計測することができる。したがって、防水塗膜１３０の膜厚を定量的に確認することが可能となる。このとき、特に導電性テープ１１０が上下方向に延びていることにより、防水塗膜１３０の膜厚を、上下方向の任意の位置で確認することができる。したがって、膜厚が薄い箇所に更に追加で防水塗料を塗布することにより、壁面１０２全体において防水塗膜１３０の膜厚が均一化され、防水性能を高めることが可能となる。なお導電性テープ１１０は、下は足元まで（壁面１０２の地際近傍まで）延びていることが好ましい。人間（作業員）が塗布する場合、足元の膜厚が最も不安定になりやすいためである。 According to the said structure, the film thickness of the waterproof coating 130 can be measured using the eddy current type film thickness meter by forming the waterproof coating 130 on the electroconductive tape 110. FIG. Therefore, the film thickness of the waterproof coating 130 can be confirmed quantitatively. At this time, in particular, since the conductive tape 110 extends in the vertical direction, the film thickness of the waterproof coating 130 can be confirmed at an arbitrary position in the vertical direction. Therefore, by additionally applying a waterproof paint to a portion having a small film thickness, the film thickness of the waterproof coating 130 is made uniform over the entire wall surface 102, and the waterproof performance can be improved. In addition, it is preferable that the conductive tape 110 extends below to the feet (to the vicinity of the ground of the wall surface 102). This is because when a human (worker) applies it, the film thickness at the foot is most likely to be unstable.
上述したように、防水塗料を塗布する前にプライマー１２０を塗布することにより、防水塗膜と導電性テープの伸縮力の違いによる引っ張り力を緩和することで、欠損の発生を抑制することができる。また導電性テープ１１０を貼着した後にプライマー１２０を塗布することにより、導電性テープ１１０上にもプライマー１２０の皮膜が形成され、導電性テープの厚みによる凹凸も平滑となる。 As described above, by applying the primer 120 before applying the waterproof paint, it is possible to suppress the occurrence of defects by reducing the tensile force due to the difference in the stretching force between the waterproof coating and the conductive tape. . Further, by applying the primer 120 after the conductive tape 110 is adhered, a film of the primer 120 is also formed on the conductive tape 110, and the unevenness due to the thickness of the conductive tape becomes smooth.
ここで発明者らは、導電性テープ１１０を貼着する前にプライマー１２０を塗布する構成についても実験を行った。 Here, the inventors also conducted an experiment on a configuration in which the primer 120 was applied before the conductive tape 110 was adhered.
図３は試験片Ａ（実施例）と試験片Ｂ（比較例）を説明する図、図４は欠損を説明する図である。試験片Ａ，Ｂのいずれも、壁面としてウレタン下地１０２ａを用いた。導電性テープ１１０としてアルミテープを用いた。防水塗膜１３０としては、ポリウレア樹脂（三井化学産資：スワエール）を用いた。 FIG. 3 is a diagram illustrating a test piece A (Example) and a test piece B (Comparative Example), and FIG. 4 is a diagram illustrating a defect. In both test pieces A and B, the urethane base 102a was used as the wall surface. An aluminum tape was used as the conductive tape 110. As the waterproof coating 130, polyurea resin (Mitsui Chemicals: Swale) was used.
図３（ａ）に示す試験片Ａ（実施例）と図３（ｂ）に示す試験片Ｂ（比較例）とでは、導電性テープ１１０とプライマー１２０を施す順番が異なっている。試験片Ａでは、１ｍ四方のウレタン下地１０２ａの上に１ｍの導電性テープ１１０を５本貼り付け、導電性テープ１１０の上から圧着して下地に密着させた。その後にプライマー１２０を塗布し、防水塗膜１３０を吹きつけた。試験片Ｂでは、プライマー１２０を塗布した後に導電性テープ１１０を貼り付けた。 The test piece A shown in FIG. 3A (Example) and the test piece B shown in FIG. 3B (Comparative Example) differ in the order in which the conductive tape 110 and the primer 120 are applied. In the test piece A, five 1 m conductive tapes 110 were affixed on a 1 m square urethane substrate 102a, and were pressure-bonded from above the conductive tape 110 to adhere to the substrate. After that, the primer 120 was applied and the waterproof coating 130 was sprayed. In the test piece B, the conductive tape 110 was affixed after applying the primer 120.
すると試験片Ｂでは、図４に示すように、防水塗膜１３０において、導電性テープ１１０の縁の近傍に欠損が発生した。試験片Ｂで欠損が生じた原因について推察すると、導電性テープ１１０の縁部に段差が生じているため、防水塗膜１３０が硬化する際の凝縮により欠損（切れ目）が発生してしまうものと予想される。 Then, in the test piece B, as shown in FIG. 4, in the waterproof coating 130, a defect occurred near the edge of the conductive tape 110. Assuming the cause of the defect in the test piece B, there is a step at the edge of the conductive tape 110, and the defect (cut) occurs due to condensation when the waterproof coating 130 is cured. is expected.
これに対し試験片Ａでは、防水塗膜１３０における欠損が発生しなかった。これは、導電性テープ１１０がプライマー１２０に被覆されることにより、導電性テープ１１０の縁部の付着面との段差が埋まり、平滑になったものと考えられる。このことからも、導電性テープ１１０を貼着した後にプライマー１２０を塗布するという順番が好ましいことが理解できる。 On the other hand, in the test piece A, a defect in the waterproof coating 130 did not occur. This is thought to be because the conductive tape 110 was covered with the primer 120, so that the step with the adhesion surface at the edge of the conductive tape 110 was filled and smoothed. Also from this, it can be understood that the order in which the primer 120 is applied after the conductive tape 110 is adhered is preferable.
導電性テープ１１０を貼着する間隔としては、作業員が防水塗料の塗布作業をする際の移動間隔の半分程度の間隔とすることが好ましい。例えば、作業員が防水塗料の塗布作業をするときに１ｍずつ移動する場合には、導電性テープ１１０は５０ｃｍ間隔で貼着するとよい。これにより、適切な間隔で防水塗膜１３０の膜厚を計測することが可能となる。 The interval at which the conductive tape 110 is attached is preferably about half the movement interval when the worker performs the waterproof paint application operation. For example, when the worker moves by 1 m when applying the waterproof paint, the conductive tape 110 may be attached at intervals of 50 cm. Thereby, the film thickness of the waterproof coating 130 can be measured at appropriate intervals.
具体例として、幅１３．３ｍ、奥行き７．６ｍ、高さ１２．５ｍの防水層を５槽備えた施設では、５０ｃｍ間隔で導電性テープ１１０を貼り付けると、１槽あたり１１９９ｍ、５槽で５９９５ｍになる。ここで図３に示した試験片Ｂ（比較例）のように５ｍに１つの割合で欠損があると仮定すると、１２００個程度の欠損が発生する計算になる。欠損は補修して埋める必要があるため、その数が多くなると工期および費用の増大を招いてしまう。すなわち本発明によれば、欠損の発生を防止し、導電性テープ１１０の貼着延長が長くなる場合でもプライマー塗布の品質を確保することができる。 As a specific example, in a facility equipped with 5 waterproof layers having a width of 13.3 m, a depth of 7.6 m, and a height of 12.5 m, when the conductive tape 110 is pasted at intervals of 50 cm, 1199 m per tank and 5 tanks 5995m. Here, assuming that there is a defect at a rate of 1 per 5 m as in the test piece B (comparative example) shown in FIG. 3, the calculation results in about 1200 defects. Since defects need to be repaired and filled, an increase in the number leads to an increase in work period and cost. That is, according to the present invention, it is possible to prevent the occurrence of defects and ensure the quality of primer application even when the sticking extension of the conductive tape 110 becomes long.
図５は、渦電流式膜厚計１００による測定位置について説明する図である。図５（ａ）に示すように、渦電流式膜厚計１００は、円筒形のプローブ１００ａ、およびそれに接続された測定装置１０４を備える。プローブ１００ａの中心にはコア１００ｂが配置されている。本実施形態では、図５（ａ）に示す直径１６ｍｍのプローブ１００ａを用いて防水塗膜１３０の膜厚を測定する場合を例示して説明する。 FIG. 5 is a diagram for explaining a measurement position by the eddy current film thickness meter 100. As shown in FIG. 5A, the eddy current film thickness meter 100 includes a cylindrical probe 100a and a measuring device 104 connected thereto. A core 100b is disposed at the center of the probe 100a. In this embodiment, the case where the film thickness of the waterproof coating 130 is measured using the probe 100a having a diameter of 16 mm shown in FIG.
図５（ｂ）に示すように、渦電流式膜厚計１００のプローブ１００ａが導電性テープ１１０の外側にある場合は、当然にして防水塗膜１３０の膜厚は計測できない。図５（ｃ）に示すように、プローブ１００ａの一部が導電性テープ１１０上に位置する場合、プローブ１００ａのコア１００ｂは導電性テープ１１０の縁の上に位置する。この場合、計測値は、実際の膜厚よりも厚い値が出る。すなわち、誤差が生じるため信頼性のある値を得られない。図５（ｄ）に示すように、プローブ１００ａの全体が導電性テープ１１０上に位置する場合、コア１００ｂは導電性テープ１１０の中心に位置し、正確な膜厚が計測される。 As shown in FIG. 5B, when the probe 100 a of the eddy current film thickness meter 100 is outside the conductive tape 110, the film thickness of the waterproof coating 130 cannot be measured. As shown in FIG. 5C, when a part of the probe 100 a is located on the conductive tape 110, the core 100 b of the probe 100 a is located on the edge of the conductive tape 110. In this case, the measured value is larger than the actual film thickness. That is, since an error occurs, a reliable value cannot be obtained. As shown in FIG. 5D, when the entire probe 100a is positioned on the conductive tape 110, the core 100b is positioned at the center of the conductive tape 110, and an accurate film thickness is measured.
図６は、導電性テープ１１０の幅による計測値の誤差について説明する図である。図６（ａ）は、導電性テープ１１０の幅が２０ｍｍのときの膜厚の計測値である。図６（ｂ）は、導電性テープ１１０の幅が２５ｍｍのときの膜厚の計測値である。図６（ｃ）は、導電性テープ１１０の幅が３０ｍｍのときの膜厚の計測値である。膜厚の計測では、各幅の導電性テープ１１０の膜厚を５回計測し、最大値および最小値を除外した３回分の計測値を評価対象とした。導電性テープ１１０の試験片には、厚み２．０６ｍｍとした。 FIG. 6 is a diagram for explaining an error in measurement values due to the width of the conductive tape 110. FIG. 6A is a measurement value of the film thickness when the width of the conductive tape 110 is 20 mm. FIG. 6B is a measured value of the film thickness when the width of the conductive tape 110 is 25 mm. FIG. 6C shows a measured value of the film thickness when the width of the conductive tape 110 is 30 mm. In the measurement of the film thickness, the film thickness of the conductive tape 110 of each width was measured five times, and the measurement values for three times excluding the maximum value and the minimum value were used as evaluation targets. The test piece of the conductive tape 110 had a thickness of 2.06 mm.
計測箇所は、導電性テープ１１０上、導電性テープ１１０の左右両縁それぞれの近傍、および導電性テープ１１０の左右両縁それぞれの外側の５か所とした。以下、導電性テープ１１０の左縁の外側の計測箇所をＰ１、導電性テープ１１０の左縁近傍の計測箇所をＰ２、導電性テープ１１０上の計測箇所をＰ３、導電性テープ１１０の右縁近傍の計測箇所をＰ４、導電性テープ１１０の右縁の外側の計測箇所をＰ５と称する。 There were five measurement points on the conductive tape 110, in the vicinity of the left and right edges of the conductive tape 110 and on the outer sides of the left and right edges of the conductive tape 110. Hereinafter, the measurement location outside the left edge of the conductive tape 110 is P1, the measurement location near the left edge of the conductive tape 110 is P2, the measurement location on the conductive tape 110 is P3, and the vicinity of the right edge of the conductive tape 110 This measurement location is referred to as P4, and the measurement location outside the right edge of the conductive tape 110 is referred to as P5.
図６（ａ）〜図６（ｃ）に示すように、導電性テープ１１０の左右の外側の計測箇所Ｐ１およびＰ５では、導電性テープ１１０の幅が２０ｍｍ〜３０ｍｍのいずれの場合においても、防水塗膜１３０の膜厚を検知することができない。また導電性テープ１１０の左右の縁近傍の計測箇所Ｐ２およびＰ４では、導電性テープ１１０の幅が２０ｍｍ〜３０ｍｍのいずれの場合においても、１箇所あたりの３つの計測値にばらつきが生じてしまう。 As shown in FIG. 6A to FIG. 6C, at the measurement points P1 and P5 on the left and right outer sides of the conductive tape 110, the conductive tape 110 is waterproof regardless of the width of 20 mm to 30 mm. The film thickness of the coating film 130 cannot be detected. Further, at the measurement locations P2 and P4 near the left and right edges of the conductive tape 110, the three measured values per location vary in any case where the width of the conductive tape 110 is 20 mm to 30 mm.
導電性テープ１１０上の計測箇所Ｐ３では、導電性テープ１１０の幅が２０ｍｍのときは、Ｐ３の３つの計測値においてばらつきが生じている。このことから、プローブ１００ａの直径が１６ｍｍのとき、導電性テープ１１０の幅が２０ｍｍであると安定した計測結果が得られないことが理解できる。一方、導電性テープ１１０の幅が２５ｍｍおよび３０ｍｍの場合、計測箇所Ｐ３では、それぞれの幅の３つの計測箇所の値が一致している。 At the measurement location P3 on the conductive tape 110, when the width of the conductive tape 110 is 20 mm, there are variations in the three measured values of P3. From this, it can be understood that when the diameter of the probe 100a is 16 mm, a stable measurement result cannot be obtained when the width of the conductive tape 110 is 20 mm. On the other hand, when the width of the conductive tape 110 is 25 mm and 30 mm, at the measurement location P3, the values of the three measurement locations of the respective widths match.
上記の結果から、導電性テープ１１０の幅とプローブ１００ａの幅の比が、「２０ｍｍ／１６ｍｍ＝１．２５」であると膜厚の計測値が安定せず、「２５ｍｍ／１６ｍｍ＝１．５６」であると膜厚の計測値が安定することがわかる。このことから、導電性テープ１１０の幅は、計測に用いる渦電流式膜厚計１００のプローブ１００ａの幅の１．５倍以上とすることが好ましいことが理解できる。 From the above results, when the ratio of the width of the conductive tape 110 and the width of the probe 100a is “20 mm / 16 mm = 1.25”, the measured value of the film thickness is not stable, and “25 mm / 16 mm = 1.56”. It can be seen that the measured value of the film thickness is stable. From this, it can be understood that the width of the conductive tape 110 is preferably 1.5 times or more the width of the probe 100a of the eddy current film thickness meter 100 used for measurement.
以上、添付図面を参照しながら本発明の好適な実施形態について説明したが、本発明はかかる実施形態に限定されないことは言うまでもない。当業者であれば、特許請求の範囲に記載された範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
