Then it is necessary to think about the antioxidant with the most, most antioxidants have a most suitable concentration scale. Within this scale, followed by the amount of antioxidants, antioxidant effectiveness added to the maximum. Beyond this scale, it will bring adverse effects. The amount of antioxidant depends on the nature of the plastic, the power of the antioxidant, synergistic effect, the conditions of use of the product and the cost of the offer and many other factors. Usually amine antioxidant activity than phenolic antioxidants, so there should be greater antioxidant function, but the former in the air under the effect of oxygen and light will change color, itself is mostly colored, and toxic, so the use in plastics to be careful. In commercial formulations, <a href=\"https:\/\/longchangchemical.com\/de\/product\/chlumiao-1010-cas-6683-19-8\/\">Antioxidationsmittel 1010<\/a> is often paired with <a href=\"https:\/\/longchangchemical.com\/de\/product\/chlumiao-168-cas-31570-04-4\/\">Antioxidant 168<\/a> to balance long-term stability and processing protection. Now the primary consideration of antioxidant cooperation.<\/p>\n<p>(l) add and effect.<\/p>\n<p>Die Verwendung einer Vielzahl von Antioxidantien, kann ihre jeweiligen Eigenschaften und Wirkungen zu f\u00f6rdern, die Erh\u00f6hung der Gesamtwirkung. Zum Beispiel kann die unterschiedliche Verdunstung oder r\u00e4umliche Best\u00e4ndigkeit der gehinderten Phenole und wenn sie verwendet werden, ihre antioxidative Wirkung in einem breiten Temperaturbereich f\u00f6rdern, die Wirkung wird verst\u00e4rkt. Wenn in der Formel nur eine Art von Antioxidans verwendet wird, ist es unvermeidlich, in einer gr\u00f6\u00dferen Menge zu beteiligen, die intensive Oxidationsreaktionen bei hohen Konzentrationen verursachen wird, was nicht erlaubt ist. Aber die Wahl von mehreren niedrigen Konzentrationen von Antioxidantien und die Verwendung, nicht nur die gew\u00fcnschte Absicht zu erreichen, und auch zu verhindern, intensive Oxidation, und tragen ihre additive Wirkung.<\/p>\n<p>(2) Synergistische Wirkung.<\/p>\n<p>Wenn zwei verschiedene Aktivit\u00e4ten der wichtigsten Antioxidans und verwenden, die hohe Aktivit\u00e4t des Antioxidans, um Wasserstoffatome zu geben, so dass die Oxidation der aktiven Kette zu stoppen; und geringe Aktivit\u00e4t des Antioxidans kann die hohe Aktivit\u00e4t des Antioxidans, um Wasserstoffatome zu liefern, so dass es regeneriert und entwickelt eine dauerhafte antioxidative Wirkung, so dass die antioxidative Wirkung ist sehr gut.<\/p>\n<p>Bei der Verwendung von Haupt- und Hilfsantioxidantien sollte auf die Entwicklung von Synergieeffekten geachtet werden. Wie die wichtigsten Antioxidans einfach geben Wasserstoffatome, Wasserstoffatome k\u00f6nnen Peroxid freie Radikale in Hydroperoxide zu machen, die Kettenreaktion zu stoppen; und dann Hydroperoxide und Hilfsantioxidans Peroxid Spaltmittel Wirkung, erzeugen inaktive Stabilisierungsprodukte. So stark verlangsamen die Geschwindigkeit der Oxidationsreaktionen, das Hinzuf\u00fcgen der antioxidative Wirkung. Wie in der Polyolefin weit in das Antioxidans 264 und DLPT-System verwendet wird, ist ein Beispiel.<\/p>\n<p>Ein Antioxidans-Molek\u00fcl hat zwei oder mehr verschiedene stabilisierende Funktionen, sagte, da die synergistische Wirkung, wie Schwefel-haltigen gehindert phenolischen Antioxidans, hat es eine Kettenreaktion zu stoppen und Peroxid-Differenzierung Mittel der Zwei-Schicht-Effekt, dieses Antioxidans kann die antioxidative Wirkung zu st\u00e4rken, ist eine w\u00fcnschenswerte Antioxidans.<\/p>\n<p>Antioxidans und Hitze, Licht Stabilisator, sollte ausgew\u00e4hlt werden, um eine synergistische Wirkung haben, und bem\u00fchen uns, gegens\u00e4tzliche Effekte zu verhindern. Wie die meisten Amin und phenolische Antioxidantien, in der Gegenwart von Ru\u00df deutlich reduziert die Wirksamkeit der gegens\u00e4tzlichen Wirkung, die durch Ru\u00df direkt katalysieren die Oxidation von Antioxidantien sein kann, verarmt einige der Antioxidans verursacht durch. Thioether gebundenen Antioxidans und Ru\u00df, aber es ist ein synergistischer Effekt. Daher sollte die erste aufgegeben werden, und die letztere sollte verwendet werden.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>A practical selection route for antioxidant, UV absorber, and HALS packages<\/h2>\n<p>Most stabilizer decisions work best when they are treated as package decisions rather than single-product decisions.
