Plastic recycling is essential as the world continues to emphasize sustainability. Recycled plastic pellets from post-consumer and industrial waste offer value in various applications, including traffic cones, plastic chairs, detergent bottles, trash cans, and flower pots. 

Ensuring consistent color in products made from reprocessed materials can be complex. Here at HunterLab, we offer a range of solutions to measure the color of recycled pellets for precise results.

Challenges in Measuring Recycled Materials

Quantifying color in recycled plastic pellets presents unique challenges, such as:

• Material variations: Recycled pellets contain plastics from different sources, resulting in color variations. They are often blended to achieve a desired color. Color measurement can help ensure consistent blending ratios and a uniform final product color.
• Contamination: Foreign materials present in recycled pellets can affect color measurement accuracy. Implementing measures to minimize contamination in recycled pellets can improve color consistency.
• Physical form: Recycled pellets vary in size, shape, and opacity, affecting how light interacts with the material during measurement. These properties demand the right equipment and measurement methods for precision and consistency.

Best Practices for Precise Color Measurement

Spectrophotometers/colorimeters are the industry standard for precise color measurement. These devices analyze how light interacts with a sample and quantify the intensity of wavelengths across the visible spectrum to translate color into numbers. The following best practices will help you make the most of this technology to support your goals:

• Prepare and present samples accurately and consistently: It is crucial to maintain consistent sample preparation. Per ASTM D6290-19, operators must use a clean, optically clear and scratch-free sample cup filled to a sufficient depth to ensure effective opacity. Additionally, covering the sample cup with an opaque cover is crucial to block ambient room light and prevent external interference during measurement.
• Measure across a large area: The larger the sample area measured, the more precise and repeatable the results. Refer to ASTM D6290-19 Standard Test Method for Color Determination of Plastic Pellets for guidance on proper measurement methods. Specifically, the standard recommends taking three separate measurements using a "dump-and-fill" technique with fresh pellets to ensure an accurate and representative average.
• Determine the relevant color spaces: Choose a shared color space to establish communication throughout the production chain.
• Leverage color quality control software: Ensure your spectrophotometer integrates with or includes built-in color quality control software. This technology allows you to compare the color of your recycled pellets to target specifications or predefined color ranges.

世界が持続可能性を重視し続ける中、プラスチックのリサイクルは不可欠なものとなっている。消費者や産業廃棄物から再生されたプラスチックペレットは、交通コーン、プラスチック椅子、洗剤ボトル、繊維製品、ゴミ箱、植木鉢など、さまざまな用途に使用できる。 

再加工材料から作られた製品の色を一定に保つことは、難しいことです。HunterLabでは、正確な結果を得るための再生ペレットの色測定ソリューションを提供しています。

リサイクル素材測定の課題

再生プラスチックペレットの色の測定は、製造業者にとって次のようなユニークな課題をもたらす：

• 素材のバリエーション： リサイクルペレットにはさまざまな原料のプラスチックが含まれているため、色のバリエーションがある。希望の色に仕上げるためにブレンドされることがよくあります。色測定は、一貫したブレンド比率と均一な最終製品の色を確保するのに役立ちます。
• 汚染: 再生ペレットに含まれる異物は、色の測定精度に影響を及ぼす可能性がある。再生ペレットの汚染を最小限に抑える対策を実施することで、色の一貫性を向上させることができます。
• 物理的形状：再生ペレットはサイズ、形状、不透明度が異なることがあり、測定中に光が材料とどのように相互作用するかに影響するため、正確さと再現性のために適切な機器と測定方法が必要となる。

Das Recycling von Kunststoffen wird immer wichtiger, da die Welt immer mehr Wert auf Nachhaltigkeit legt. Recycelte Kunststoffgranulate aus Post-Consumer- und Industrieabfällen können in verschiedenen Anwendungen eingesetzt werden, z. B. für Verkehrsleitkegel, Plastikstühle, Waschmittelflaschen, Textilien, Mülleimer und Blumentöpfe. 

Die Sicherstellung einer einheitlichen Farbe bei Produkten aus wiederaufbereiteten Materialien kann eine Herausforderung sein. Hier bei HunterLab bieten wir eine Reihe von Lösungen zur Messung der Farbe von recycelten Pellets für genaue Ergebnisse.

Herausforderungen bei der Messung recycelter Materialien

Die Messung der Farbe von recyceltem Kunststoffgranulat stellt die Hersteller vor besondere Herausforderungen, wie zum Beispiel:

• Materialschwankungen: Recycelte Pellets enthalten Kunststoffe aus verschiedenen Quellen, was zu Farbschwankungen führt. Sie werden oft gemischt, um die gewünschte Farbe zu erreichen. Eine Farbmessung kann dazu beitragen, ein einheitliches Mischungsverhältnis und eine einheitliche Farbe des Endprodukts zu gewährleisten.
• Verunreinigung: Fremdstoffe in recyceltem Granulat können die Genauigkeit der Farbmessung beeinträchtigen. Die Umsetzung von Maßnahmen zur Minimierung von Verunreinigungen in recycelten Pellets kann die Farbkonsistenz verbessern.
• Physikalische Form: Recycelte Pellets können in Größe, Form und Opazität variieren, was sich auf die Interaktion des Lichts mit dem Material während der Messung auswirkt und die richtige Instrumentierung und Messmethode für Genauigkeit und Wiederholbarkeit erfordert.

El reciclado de plástico se está convirtiendo en algo esencial a medida que el mundo sigue haciendo hincapié en la sostenibilidad. Los gránulos de plástico reciclado procedentes de residuos industriales y de posconsumo pueden utilizarse en diversas aplicaciones, como conos de tráfico, sillas de plástico, botellas de detergente, textiles, cubos de basura y macetas. 

Garantizar un color uniforme en los productos fabricados con materiales reprocesados puede ser todo un reto. Aquí en HunterLab, ofrecemos una gama de soluciones para medir el color de pellets reciclados para obtener resultados precisos.

Retos de la medición de materiales reciclados

La medición del color de los gránulos de plástico reciclado presenta retos únicos para los fabricantes, como:

• Variaciones de material: Los gránulos reciclados contienen plásticos de diversas procedencias, lo que da lugar a variaciones de color. A menudo se mezclan para conseguir el color deseado. La medición del color puede ayudar a garantizar proporciones de mezcla coherentes y un color uniforme del producto final.
• Contaminación: Los materiales extraños presentes en los granulados reciclados pueden afectar a la precisión de la medición del color. La aplicación de medidas para minimizar la contaminación en los granulados reciclados puede mejorar la uniformidad del color.
• Forma física: Los gránulos reciclados pueden variar en tamaño, forma y opacidad, lo que afecta a la forma en que la luz interactúa con el material durante la medición y requiere la instrumentación y los métodos de medición adecuados para obtener precisión y repetibilidad.

Consistent color is crucial for plastic products since it impacts brand identity and marketability. Plastic's appearance is based on opacity, texture, and gloss. Every modern manufacturer of opaque sheet plastic must always deliver the correct color to consumers. 

HunterLab's color measurement solutions help execute quality control throughout manufacturing processes. 

Factors that Affect the Appearance of Color

Environmental factors, optical illusions, and surface conditions determine the appearance of an object's color. Other factors include:

• Subjectivity: Eye sensitivity varies from person to person, causing color to appear different.
• Light sources: Different types of light, such as fluorescent, incandescent, and sunlight, have different effects on the appearance of color.
• Surfaces: Surface conditions such as texture and glossiness influence the object's color.
• Background: An object can appear a different color against a bright or dark background.
• Surface area: A color covering a large surface area appears brighter and more vivid than when covering a small object.

Spectrophotometers for the Color Measurement of Opaque Sheet Plastic

HunterLab offers instruments suited for color measurement of opaque plastics. Our Agera spectrophotometer caters to opaque plastics like films, sheets, enclosures, and pellets. It measures color across a spectrum with UV control. Additionally, it incorporates a 60-degree gloss measurement and a 5-megapixel camera to assist with sample positioning.
