Application :<\/strong>
\nLe CHLUMIAO\u00ae DLTDP est un excellent antioxydant auxiliaire, largement utilis\u00e9 dans le polypropyl\u00e8ne, le poly\u00e9thyl\u00e8ne, l'ABS, le PBT et d'autres mat\u00e9riaux synth\u00e9tiques, et peut \u00e9galement \u00eatre utilis\u00e9 dans le traitement du caoutchouc et les graisses lubrifiantes. Ce produit est principalement utilis\u00e9 en combinaison avec des antioxydants ph\u00e9noliques principaux pour produire un effet synergique, ce qui peut augmenter consid\u00e9rablement l'effet antioxydant de l'antioxydant principal et am\u00e9liorer les performances de traitement et la dur\u00e9e de vie du produit. En raison de sa faible toxicit\u00e9, il peut \u00eatre utilis\u00e9 pour fabriquer des films d'emballage alimentaire.<\/p>\n

Stockage :<\/strong><\/p>\n

\u00c9viter l'exposition au soleil ou le stockage \u00e0 haute temp\u00e9rature, et conserver dans un endroit frais, sec et ventil\u00e9 pour \u00e9viter l'humidit\u00e9, l'eau et la chaleur.<\/p>\n

Paquet :<\/strong>
\nUtiliser un carton doubl\u00e9 d'un sac en plastique, le poids net de chaque carton est de 25 kg.<\/p>\n

Effet de coordination des antioxydants ph\u00e9noliques
\n1, effet synergique<\/p>\n

Lorsque deux antioxydants \u00e0 terminaison de cha\u00eene, tels que des ph\u00e9nols encombr\u00e9s, sont utilis\u00e9s, la forte activit\u00e9 de l'antioxydant donne des atomes d'hydrog\u00e8ne, de sorte que les radicaux libres sont inactifs ; et la faible activit\u00e9 de l'antioxydant peut \u00eatre utilis\u00e9e pour la forte activit\u00e9 de l'antioxydant qui fournit des atomes d'hydrog\u00e8ne pour le r\u00e9g\u00e9n\u00e9rer, de sorte que l'efficacit\u00e9 \u00e0 long terme de l'effet antioxydant est meilleure. Diff\u00e9rentes obstructions spatiales de l'antioxydant lorsqu'il est utilis\u00e9 conjointement, mais aussi l'inhibition de l'effet de transfert des radicaux libres. Par exemple, apr\u00e8s l'arr\u00eat des radicaux peroxyles (ROO\u30fb) par des ph\u00e9nols encombr\u00e9s tr\u00e8s actifs, les radicaux aryloxyle g\u00e9n\u00e9r\u00e9s peuvent facilement d\u00e9clencher le vieillissement oxydatif des macromol\u00e9cules. Le ph\u00e9nol encombr\u00e9 \u00e0 faible activit\u00e9 peut amener les radicaux aryloxyle \u00e0 g\u00e9n\u00e9rer le ph\u00e9nol encombr\u00e9 \u00e0 forte activit\u00e9, \u00e9vitant ainsi l'effet de transfert de cha\u00eene caus\u00e9 par l'interaction entre les radicaux aryloxyle et les macromol\u00e9cules.<\/p>\n

 <\/p>\n

Le ph\u00e9nol entrav\u00e9 et le d\u00e9composeur d'hydroperoxyde et leur utilisation, d'une part, peuvent permettre la r\u00e9g\u00e9n\u00e9ration de l'antioxydant principal, d'autre part, peuvent d\u00e9composer l'hydroperoxyde, l'effet synergique est plus fort, c'est l'antioxydant actuel des plastiques qui est souvent utilis\u00e9 comme \"partenaire en or\", tel que l'antioxydant 1010 et l'antioxydant 168 de l'utilisation de l'antioxydant. La m\u00eame mol\u00e9cule avec deux ou plusieurs m\u00e9canismes de stabilisation diff\u00e9rents et la r\u00e9action synergique, connue sous le nom d'effet auto-synergique. Par exemple, l'antioxydant 300 et l'antioxydant 2246-S fonctionnent simultan\u00e9ment comme antioxydants primaires et secondaires.<\/p>\n

En outre, l'antioxydant principal et l'absorbeur d'ultraviolets, le passivateur d'ions m\u00e9talliques peuvent \u00e9galement produire un effet synergique. Le stabilisateur composite de l'antioxydant principal pour les antioxydants ph\u00e9noliques, tels que l'antioxydant 1010, l'antioxydant 1076, l'antioxydant 264, etc., l'antioxydant secondaire pour le phosphite, l'antioxydant 168, les principales vari\u00e9t\u00e9s d'antioxydants composites sur le march\u00e9 sont pour la plupart des produits import\u00e9s.<\/p>\n

2, contre l'effet<\/p>\n

Par exemple, les amines et les antioxydants ph\u00e9noliques sur les plastiques de poly\u00e9thyl\u00e8ne sont les principaux antioxydants efficaces, le noir de carbone est \u00e9galement un antioxydant tr\u00e8s efficace, mais lorsque des amines ou des antioxydants ph\u00e9noliques encombr\u00e9s sont ajout\u00e9s au poly\u00e9thyl\u00e8ne contenant du noir de carbone, non seulement les deux n'ont pas d'effet synergique, mais la stabilit\u00e9 originale de leurs effets respectifs est pire, c'est-\u00e0-dire que l'effet antagoniste est produit. Cet effet antagoniste n'est pas seulement li\u00e9 au type d'antioxydant, mais aussi aux vari\u00e9t\u00e9s de r\u00e9sine, comme dans les plastiques ABS, le noir de carbone et le ph\u00e9nol encombr\u00e9, qui non seulement n'ont pas d'effet antagoniste, mais ont aussi un effet synergique plus important.<\/p>\n

3. Effet d'oxydation important<\/p>\n

Lorsque la concentration d'antioxydant dans le syst\u00e8me polym\u00e8re d\u00e9passe une certaine valeur, l'antioxydant r\u00e9agit directement avec l'oxyg\u00e8ne mol\u00e9culaire, les mol\u00e9cules d'antioxydant sont sujettes \u00e0 la formation de nouveaux radicaux libres et produisent une r\u00e9action d'oxydation renforc\u00e9e. Par cons\u00e9quent, l'utilisation g\u00e9n\u00e9rale d'antioxydants a une concentration critique de la meilleure utilisation de la gamme de concentration, sinon le dosage est trop \u00e9lev\u00e9 au lieu de produire une r\u00e9action d'oxydation renforc\u00e9e, acc\u00e9l\u00e9rant ainsi le vieillissement des polym\u00e8res.<\/p>","protected":false},"excerpt":{"rendered":"
