Description
本発明は、樹脂成形体における露出固形材料の測定方法に関する。 The present invention relates to a method for measuring an exposed solid material in a resin molded body.
従来、樹脂と、樹脂とは異なる固形材料を複合した樹脂成形体がある。この種の樹脂成形体においては、外観や手触り等の観点から固形材料が樹脂成形体の表面に浮き出ないことが望ましい場合がある。また、水分や日光に直接晒されることで、劣化したり、変色したりしやすい植物繊維等のセルロース材料を含む樹脂成形体では、耐久性等の観点から、セルロース材料が外部環境に晒されないことが望ましい。また、このような樹脂成形体では、固形材料が表面に浮き出て露出するだけでなく、固形材料を含むが故に表層に微細なクラックが生じやすく、成形体の表面近くに内包された固形材料がクラックを通じて外部環境に晒される場合もある。これらの外部環境に晒されている固形材料（露出した固形材料）について、従来、その量を測定する方法は見当たらない。 Conventionally, there is a resin molded body in which a resin and a solid material different from the resin are combined. In this type of resin molded body, it may be desirable that the solid material does not float on the surface of the resin molded body from the viewpoint of appearance or touch. In addition, in resin molded products containing cellulose materials such as plant fibers that are easily deteriorated or discolored by direct exposure to moisture and sunlight, the cellulose materials should not be exposed to the external environment from the viewpoint of durability. Is desirable. Further, in such a resin molded body, not only the solid material floats on the surface and is exposed, but also because the solid material is included, fine cracks are likely to occur in the surface layer, and the solid material enclosed near the surface of the molded body In some cases, it may be exposed to the external environment through cracks. Conventionally, there is no method for measuring the amount of these solid materials exposed to the external environment (exposed solid materials).
製品の表面の欠陥を検出する方法としては、下記特許文献１に、大型計算機用磁気ディスク装置等に使用されている薄膜磁気ヘッドの表面上の凹状欠陥と凸状異物を検出する方法が開示されている。この方法は、薄膜磁気ヘッドの平坦部に落斜照明したときに、平坦な正常部分と、凹状欠陥及び凸状異物部分とで、反射光に明暗の差が生じることを利用するものである。具体的には、落斜照明されている平坦部の検査領域に対する撮影画像を２値化処理して、正常部分と、凹状欠陥及び凸状異物部分とを識別する。 As a method for detecting defects on the surface of a product, the following Patent Document 1 discloses a method for detecting concave defects and convex foreign matter on the surface of a thin film magnetic head used in a magnetic disk device for a large computer. ing. This method utilizes the fact that when a flat portion of a thin film magnetic head is illuminated obliquely, there is a difference in brightness between reflected light between a flat normal portion and concave defects and convex foreign matter portions. Specifically, the captured image for the inspection area of the flat part illuminated by the oblique illumination is binarized to identify the normal part and the concave defect and convex foreign substance part.
このような薄膜磁気ヘッドの表面の欠陥を検出する方法は、極めて滑らかな平坦面における凹凸の検出には有効である。しかし、検査領域の形状が平坦ではない場合や、平坦であってもその平滑性の精度が低い場合には、反射光の明暗によって、正常部分と欠陥部分とを必ずしも的確に識別することができない。したがって、種々の形状に成形される樹脂成形体において、露出した固形材料を検出するのに応用できる技術ではない。 Such a method for detecting defects on the surface of a thin film magnetic head is effective for detecting irregularities on a very smooth flat surface. However, when the shape of the inspection region is not flat or when the accuracy of the smoothness is low even if it is flat, the normal part and the defective part cannot always be accurately identified by the brightness of the reflected light. . Therefore, it is not a technique that can be applied to detecting an exposed solid material in a resin molded body molded into various shapes.
そこで、本発明では、樹脂と、樹脂とは異なる材質の固形材料とを含む樹脂成形体において、露出している固形材料の量を測定することを課題とした。 Therefore, an object of the present invention is to measure the amount of exposed solid material in a resin molded body including a resin and a solid material made of a material different from the resin.
本発明は、樹脂と、前記樹脂とは異なる材質の固形材料と、を含む樹脂成形体において露出する固形材料の量を測定する、樹脂成形体における露出固形材料の測定方法であり、検体作成工程と、測定工程とを備える。検体作成工程は、前記固形材料と接触すると、その接触した固形材料の色を変化させることのできる薬液に前記樹脂成形体を接触させ、前記薬液の作用により前記露出する固形材料の色を他の構成材料の色と相違するように変化させて前記樹脂成形体の検体を作成する工程である。測定工程は、前記検体の外観の画像を取得し、該画像を画像処理することにより前記露出する固形材料を他の構成材料との色の相違に基づき検出して、前記露出する固形材料の量を測定する工程である。 The present invention is a method for measuring an exposed solid material in a resin molded body, which measures an amount of a solid material exposed in a resin molded body including a resin and a solid material of a material different from the resin. And a measuring step. When the specimen preparation step is brought into contact with the solid material, the resin molding is brought into contact with a chemical solution that can change the color of the solid material in contact with the solid material, and the color of the exposed solid material is changed to another color by the action of the chemical solution. In this step, the specimen of the resin molded body is prepared by changing the color so as to be different from the color of the constituent material. In the measurement step, an image of the appearance of the specimen is acquired, and the exposed solid material is detected based on a color difference from other constituent materials by performing image processing on the image, and the amount of the exposed solid material It is the process of measuring.
この測定方法によれば、検体を作成するにあたり、樹脂成形体を薬品と接触させることで、外部環境に晒されている固形材料に直接薬品を作用させるため、露出する固形材料を確実に着色させることができる。そして、検体の外観の画像を画像処理することにより、露出する固形材料を検出することで、その量を測定して数値化することができる。 According to this measurement method, when the specimen is prepared, the resin molded body is brought into contact with the chemical, so that the chemical directly acts on the solid material exposed to the external environment, so that the exposed solid material is surely colored. be able to. Then, by performing image processing on an image of the appearance of the specimen, by detecting the exposed solid material, the amount can be measured and digitized.
一実施形態において、前記固形材料はセルロース材料であり、前記薬液は前記セルロース材料と接触することで該セルロース材料を炭化させる酸性溶液であり、前記樹脂は前記酸性溶液によって炭化しない樹脂である。前記樹脂がポリオレフィン樹脂であり、前記固形材料がセルロース材料である場合、前記薬液としては、硫酸を用いることができる。 In one embodiment, the solid material is a cellulose material, the chemical solution is an acidic solution that carbonizes the cellulose material by contact with the cellulose material, and the resin is a resin that is not carbonized by the acidic solution. When the resin is a polyolefin resin and the solid material is a cellulose material, sulfuric acid can be used as the chemical solution.
本発明によれば、樹脂と、樹脂とは異なる材質の固形材料とを含む樹脂成形体において、露出している固形材料の量を測定することができる。 ADVANTAGE OF THE INVENTION According to this invention, in the resin molding containing resin and the solid material of the material different from resin, the quantity of the exposed solid material can be measured.

〔露出固形材料の測定方法〕
本発明の樹脂成形体における露出固形材料の測定方法は、検体作成工程と、測定工程と、をこの順で備える。
[Measurement method of exposed solid material]
The method for measuring an exposed solid material in the resin molded body of the present invention includes a specimen preparation step and a measurement step in this order.
（検体作成工程）
検体作成工程では、測定に供する樹脂成形体を薬液に接触させて検体を作成する。検体作成工程で用いる薬液は、接触した固形材料の色を樹脂の色と相違するように変化させることのできるものである。つまり、薬液に接触した固形材料は色が変化することにより、接触していない固形材料と異なる色になるとともに、樹脂とも異なる色になる。ここで、色が相違する（異なる）ことは、色味又は濃淡のいずれかが相違することを意味する。検体は、薬液に接触した固形材料の色が変化した後に、樹脂や薬液に接触していない固形材料と色が相違しているものである。そうであれば、薬液に接触した樹脂が元の色から変化していても構わない。
(Sample preparation process)
In the specimen preparation step, a specimen is prepared by bringing a resin molded body to be used for measurement into contact with a chemical solution. The chemical solution used in the specimen preparation step can change the color of the solid material that comes into contact with the resin so that it is different from the color of the resin. In other words, the color of the solid material that has come into contact with the chemical liquid changes to a color different from that of the solid material that has not been in contact, and a color different from that of the resin. Here, the difference in color (difference) means that either the color or shading is different. The specimen is different in color from the solid material not in contact with the resin or the chemical liquid after the color of the solid material in contact with the chemical liquid is changed. If so, the resin in contact with the chemical may be changed from the original color.
検体作成工程で用いる薬液は、あらゆる液体状の薬品の中から選択することができ、測定の対象となる樹脂成形体を構成する樹脂と固形材料の材質に対応して個別に選択される。例えば、樹脂がポリオレフィン樹脂であり、固形材料がセルロース材料である場合には、硫酸、塩酸、硝酸等の強酸性の薬液を用いることができる。この場合、ポリオレフィン樹脂は薬品に接触しても変色しない。しかし、薬液に接触したセルロース材料は黒く変色する。これは、酸によりセルロースが炭化することによる。この場合、薬液の濃度および接触時間は、セルロース材料が変色するが崩壊しないように設定される。硫酸を用いる場合の濃度の目安は、５〜６０ｗｔ％である。６０ｗｔ％より高濃度の硫酸や濃硫酸を用いることもできるが、粘度が高くなり、樹脂成形体の表面の微細なクラックに入り込みにくいため、クラック内で露出するセルロース材料には接触させにくい。接触時間は、薬液の濃度に応じて適宜設定される。例えば、ポリプロピレンに木粉が含まれる樹脂成形体を５０ｗｔ％の硫酸に１週間浸漬することで、接触した木粉（露出した木粉）を確実に変色させることができる。 The chemical solution used in the specimen preparation step can be selected from all liquid chemicals, and is individually selected according to the resin and solid material constituting the resin molding to be measured. For example, when the resin is a polyolefin resin and the solid material is a cellulose material, a strongly acidic chemical solution such as sulfuric acid, hydrochloric acid, or nitric acid can be used. In this case, the polyolefin resin does not change color even when it comes into contact with chemicals. However, the cellulose material in contact with the chemical solution turns black. This is because cellulose is carbonized by acid. In this case, the concentration of the chemical solution and the contact time are set so that the cellulose material changes color but does not collapse. The standard of the density | concentration in the case of using a sulfuric acid is 5-60 wt%. Although sulfuric acid or concentrated sulfuric acid having a concentration higher than 60 wt% can be used, the viscosity becomes high and it is difficult to enter into fine cracks on the surface of the resin molded body, so that it is difficult to contact the cellulose material exposed in the cracks. The contact time is appropriately set according to the concentration of the chemical solution. For example, by immersing a resin molded body containing wood powder in polypropylene for 1 week in 50 wt% sulfuric acid, it is possible to reliably change the color of the contacted wood powder (exposed wood powder).
選択される薬液が接触することにより固形材料が変色する原理は、特に限定されない。例えば、樹脂は染まりにくいが固形材料は染まりやすい染料を薬液として選択することもできる。 There is no particular limitation on the principle of discoloration of the solid material by contact with the selected chemical solution. For example, it is also possible to select a dye that is difficult to dye a resin but easy to dye a solid material as a chemical solution.
検体作成工程について、図１を参照しながら、更に詳しく説明する。樹脂成形体１１では、樹脂２１中に固形材料３１が分散した状態で含まれている。検体作成工程では、樹脂成形体１１の少なくとも測定の対象となる表面１３に薬液４１を接触させる。接触させる方法としては、薬液４１に樹脂成形体１１全体又は一部を浸漬させたり、或いは、薬液４１を表面１３に乗せたりすることができる。樹脂成形体１１の表面１３に薬液４１が接触すると、薬液４１に接触した固形材料３１が変色する。図１においては、変色する固形材料３１を黒く塗りつぶして示している。樹脂成形体１１に含まれる固形材料３１のうち、表面１３に浮き出ることで外部に晒されている固形材料３５は、薬液４１の作用で変色する。また、樹脂成形体１１の表面１３から内部へ進行する裂け目（クラック１５）にも薬液４１が入り込むため、クラック１５を通じて外部に晒されている固形材料３７も変色する。このように、露出した固形材料３５，３７が変色して検体が得られる。
The specimen preparation process will be described in more detail with reference to FIG. In the resin molded

測定工程では、検体作成工程で得られた検体の測定対象部分の外観の画像を取得し、画像処理し、露出する固形材料を他の構成材料（樹脂及び露出していない固形材料）との色の相違に基づき検出する。図２には、検体Ｋを測定対象部分である表面１３側から見た様子が示されている。表面１３に露出した固形材料３５のみならず、樹脂２１に埋まった露出していない固形材料３３や、クラック１５を通じて露出した固形材料３７が透けて見えている。
(Measurement process)
In the measurement process, an image of the appearance of the measurement target part of the specimen obtained in the specimen preparation process is acquired, image-processed, and the exposed solid material is colored with other constituent materials (resin and unexposed solid material) Detect based on the difference. FIG. 2 shows a state in which the specimen K is viewed from the
画像処理としては、２値化が最も好ましく採用される。図３には、図２で示される検体Ｋの画像を２値化した画像が示されている。変色した固形材料３５，３７と、他の構成材料である樹脂２１及び露出していない固形材料３３との画素値を分離することで、変色した固形材料３５，３７だけを他の構成材料とは異なる色で示し、検出することができる。図３に示される２値化した画像５１において、符号５５で示される黒色部分は、図２に示される露出した固形材料３５，３７に対応し、符号５３で示される白色部分は、他の構成材料に対応する。
As image processing, binarization is most preferably employed. FIG. 3 shows an image obtained by binarizing the image of the specimen K shown in FIG. By separating the pixel values of the discolored
露出した固形材料は、検出した画素数（面積）により、その量を測定して数値で示すことができ、これを、樹脂成形体の表面の単位面積当たりの欠陥率と定義することができる。あるいは、露出した固形材料の数により、その量を数値化してもよい。 The amount of the exposed solid material can be measured and indicated by a numerical value based on the number of detected pixels (area), and this can be defined as a defect rate per unit area of the surface of the resin molded body. Alternatively, the amount may be quantified according to the number of exposed solid materials.
〔クラックの深さの評価方法〕
上記露出固形材料の測定方法を用いて、同一の樹脂成形体について、検体を作成する際に薬液を接触させる時間を変化させて、測定される露出した固形材料の量を追跡すると、樹脂成形体の表面に生じたクラックの深さの程度を相対評価することができる。すなわち、検出されるまでに要する薬液の接触時間が長いほど、より深いクラックに起因する露出固形材料であると推測される。つまり、クラックがより深いものと推測できる。
[Evaluation method of crack depth]
When the amount of exposed solid material to be measured is tracked by changing the time for contacting the chemical solution when preparing the specimen for the same resin molded body using the above-described method for measuring the exposed solid material, The degree of the depth of the crack generated on the surface of the film can be relatively evaluated. That is, it is estimated that it is an exposed solid material resulting from a deeper crack, so that the contact time of the chemical | medical solution required until it is detected is long. That is, it can be estimated that the crack is deeper.
上記の露出固形材料の測定方法及びクラックの深さの評価方法によれば、樹脂成形体の表層の欠陥を容易に数値化することができる。これらの方法は、樹脂成形体の材料開発、成形装置開発又は成形条件の検討等に利用することができ、開発等のスピードアップに貢献するものである。 According to the method for measuring the exposed solid material and the method for evaluating the crack depth, the surface layer defects of the resin molded body can be easily quantified. These methods can be used for material development of resin molded bodies, molding apparatus development, or examination of molding conditions, and contribute to speeding up development.
