Quick answer:<\/strong> For fluorescent-whitening and food-contact discussions, buyers usually focus on specification fit, migration risk, regulatory boundaries, and how the additive behaves in the finished plastic system rather than treating it as a simple color question.<\/p>\n\n\n\n

1. L'azurant optique OB et l'azurant optique OB-1 sont des produits chimiques compl\u00e8tement diff\u00e9rents.<\/strong><\/h3>\n\n\n\n\n

2. Azurant optique OB<\/a> et Agent d'\u00e9claircissement optique OB-1<\/a>Ces deux produits se ressemblent comme deux gouttes d'eau. Lorsque de nombreuses personnes entendent pour la premi\u00e8re fois parler de l'azurant optique OB et de l'azurant optique OB-1, elles pensent que l'azurant optique OB-1 est un complexe d'ob. Avec le produit, la puret\u00e9 de l'ob est r\u00e9duite d'une unit\u00e9 pour devenir l'azurant optique OB-1. Alors, quelle est la diff\u00e9rence entre l'azurant optique OB et l'azurant optique OB-1, quel type de produit doit utiliser l'azurant optique OB et quel type de produit convient le mieux \u00e0 l'azurant optique OB-1 ?<\/h4>\n\n\n\n

Nom chimique : Agent de blanchiment optique OB-1<\/h4>\n\n\n\n

L'azurant optique OB-1 convient au blanchiment des fibres chimiques telles que les fibres de polyester, les fibres de nylon et les fibres de polypropyl\u00e8ne. L'azurage et l'\u00e9claircissement du plastique polypropyl\u00e8ne, du PVC rigide, de l'ABS, de l'EVA, du polystyr\u00e8ne, du polycarbonate, etc. Il est ajout\u00e9 dans la polym\u00e9risation conventionnelle du polyester et du nylon.<\/h4>\n\n\n\n

Afin d'obtenir un blanchiment uniforme de plastiques aux propri\u00e9t\u00e9s diff\u00e9rentes, l'agent blanchissant fluorescent doit non seulement s'adapter aux conditions de traitement du plastique, mais \u00e9galement pr\u00e9senter une dispersion mol\u00e9culaire suffisante ou une solubilit\u00e9 compl\u00e8te dans le plastique. Dans le plastique, l'effet optique de blanchiment ne peut pas \u00eatre affich\u00e9 ou fortement r\u00e9duit. La s\u00e9lection des bons mod\u00e8les de diff\u00e9rents mat\u00e9riaux am\u00e9liorera consid\u00e9rablement l'effet d'\u00e9claircissement de l'agent de blanchiment fluorescent.<\/h4>\n\n\n\n

3. La formule mol\u00e9culaire de l'azurant optique OB est C26H26N2O2S et celle de l'azurant optique OB-1 est C28H18N2O2. L'image ci-dessus montre clairement qu'il s'agit de deux produits chimiques compl\u00e8tement diff\u00e9rents.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Quel produit utilise l'azurant optique OB, quel produit convient le mieux \u00e0 l'azurant optique OB-1 ?<\/strong><\/h3>\n\n\n\n

<\/p>\n\n\n\n

Bien qu'il s'agisse de deux substances chimiques diff\u00e9rentes, leur d\u00e9nomination laisse deviner qu'elles pr\u00e9sentent de nombreuses similitudes. Par exemple, l'azurant optique OB et l'azurant optique OB-1 ont un large \u00e9ventail d'applications. La plupart des mati\u00e8res plastiques et l'azurant optique OB-1 peuvent \u00eatre utilis\u00e9s en commun, et l'effet de blanchiment et d'\u00e9claircissement est \u00e9vident. Quelle est donc la diff\u00e9rence ?<\/h4>\n\n\n\n

<\/p>\n\n\n\n

1. Point de fusion : L'azurant optique OB-1>L'azurant optique OB<\/h3>\n\n\n\n

<\/p>\n\n\n\n

Le point de fusion de l'azurant optique OB \u00e9tant de 200 degr\u00e9s et celui de l'azurant optique OB-1 de 360 degr\u00e9s, l'azurant optique OB ne peut pas \u00eatre utilis\u00e9 pour les produits en plastique \u00e0 haute temp\u00e9rature, tels que les bo\u00eetiers de climatiseurs et certains ustensiles de cuisine. Par cons\u00e9quent, si votre produit n\u00e9cessite un traitement \u00e0 haute temp\u00e9rature, l'azurant optique OB-1 est votre premier choix.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

2. Dispersion et stabilit\u00e9 : Optical brightener OB>Optical brightener OB-1<\/h3>\n\n\n\n

<\/p>\n\n\n\n

Il convient tout d'abord d'expliquer qu'une bonne dispersibilit\u00e9 signifie que le produit est plus facile \u00e0 dissoudre et \u00e0 r\u00e9partir. Par exemple, la peinture et l'encre ont des exigences \u00e9lev\u00e9es en mati\u00e8re de dispersibilit\u00e9 de l'agent de blanchiment fluorescent ; une bonne stabilit\u00e9 signifie que le produit n'est pas facile \u00e0 migrer et \u00e0 jaunir \u00e0 un stade ult\u00e9rieur. Par exemple, certaines semelles de chaussures de qualit\u00e9 inf\u00e9rieure \u00e9taient blanches et propres lorsqu'elles ont \u00e9t\u00e9 achet\u00e9es pour la premi\u00e8re fois, mais elles ont jauni et se sont d\u00e9color\u00e9es apr\u00e8s un certain temps, ce qui montre que la stabilit\u00e9 de l'agent de blanchiment fluorescent est m\u00e9diocre.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Bien s\u00fbr, je ne dis pas que la dispersion et la stabilit\u00e9 de l'azurant optique OB-1 ne sont pas bonnes, mais elles sont l\u00e9g\u00e8rement moins bonnes que celles de l'ob. En raison de cette diff\u00e9rence, Lianda Fluorescence Technology ne recommande g\u00e9n\u00e9ralement pas l'utilisation de l'azurant optique OB-1 dans les rev\u00eatements d'encre et les plastiques souples. L'Ob est relativement meilleur en termes de dispersibilit\u00e9 et de r\u00e9sistance aux intemp\u00e9ries, et il n'est pas sujet au jaunissement. La situation de la migration.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Le prix est la principale diff\u00e9rence entre \u00c9claircisseur optique<\/strong><\/strong> ob et azurant optique OB-1<\/strong><\/h3>\n\n\n\n

<\/p>\n\n\n\n

En fait, la plus grande diff\u00e9rence entre l'azurant optique OB et l'azurant optique OB-1 est le prix. Je me souviens qu'il y a six ans, le prix de l'azurant optique OB \u00e9tait similaire \u00e0 celui de l'azurant optique OB-1. Toutefois, en raison des rectifications apport\u00e9es \u00e0 la protection de l'environnement \u00e0 l'\u00e9chelle nationale en Chine, l'approvisionnement en mati\u00e8res premi\u00e8res de l'azurant optique OB a connu des probl\u00e8mes, de sorte que le prix de l'azurant optique OB a grimp\u00e9 en fl\u00e8che. L'azurant optique OB est plus de deux fois plus cher que l'azurant optique OB-1. Selon les estimations du d\u00e9partement R&D de Longchang Chemical, ce prix pourrait augmenter. En raison de l'\u00e9norme diff\u00e9rence de prix, les clients qui peuvent utiliser l'azurant optique OB-1 devraient essayer de choisir l'azurant optique OB-1. Ceux qui ont des exigences particuli\u00e8res, comme les rev\u00eatements d'encre haut de gamme et les plastiques souples, sont invit\u00e9s \u00e0 utiliser l'azurant optique OB.<\/h4>\n\n\n\n

<\/p>\n\n\n\n

Face \u00e0 la flamb\u00e9e des prix de l'azurant optique OB, le d\u00e9partement R&D de Longchang Chemical a continu\u00e9 \u00e0 innover et \u00e0 d\u00e9velopper des azurants sp\u00e9ciaux adapt\u00e9s \u00e0 divers produits pour remplacer l'azurant optique OB, r\u00e9duisant ainsi les co\u00fbts pour les clients, tels que ld- pour les m\u00e9langes ma\u00eetres de couleur. s01, ld-y01 pour les rev\u00eatements sp\u00e9ciaux d'encre \u00e0 base d'huile, etc. Les clients qui en ont besoin peuvent nous contacter.<\/h4>\n\n\n\n

How buyers usually evaluate specialty additives in compliance-sensitive plastics<\/h2>\n

Food-contact and compliance-sensitive additive projects usually need a tighter screen than general industrial formulations. The strongest path usually combines specification review, migration thinking, and validation in the real polymer system.<\/p>\n

    \n
  • Start from the regulatory boundary:<\/strong> customer and market requirements often decide the screening route before formulation optimization begins.<\/li>\n
  • Check the polymer and processing route:<\/strong> the same additive can behave differently across resin systems, temperatures, and contact conditions.<\/li>\n
  • Review appearance together with compliance:<\/strong> visual performance still needs to be balanced against safety and documentation needs.<\/li>\n<\/ul>\n

    FAQ for buyers and formulators<\/h3>\n

    Why do compliance-sensitive plastic additives need more than a basic specification check?<\/strong>
    Because end-use exposure, migration limits, and customer requirements can change whether an additive is commercially acceptable.<\/p>\n

    Is visual effect enough to justify additive selection in food-contact plastics?<\/strong>
    Usually no. Appearance needs to be reviewed together with processing, documentation, and compliance fit.<\/p>\n","protected":false},"excerpt":{"rendered":"
