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. Optische witmaker OB en Optische witmaker OB-1 zijn totaal verschillende chemicali\u00ebn.<\/strong><\/h3>\n\n\n\n\n

2. Optische witmaker OB<\/a> en Optische witmaker OB-1<\/a>lijken deze twee broers. Wanneer veel mensen voor het eerst Optische witmaker OB en Optische witmaker OB-1 horen, nemen ze aan dat Optische witmaker OB-1 een complex van ob is. Met het product, wordt de zuiverheid van ob verminderd met een tot optische witmaker OB-1. Dus, wat is het verschil tussen optische witmaker OB en optische witmaker OB-1, wat voor soort product moet gebruiken optische witmaker OB, en wat voor soort product is meer geschikt voor optische witmaker OB-1.<\/h4>\n\n\n\n

Chemische naam: Optische witmaker OB-1<\/h4>\n\n\n\n

Andere Naam: Fluorescente witmaker 393; 4,4\u2032-Bis(2-benzoxazolyl)stilbeen; Fluorescente witmaker OB-1<\/h4>\n\n\n\n

De optische witmaker OB-1 is geschikt voor het wit maken van chemische vezels zoals polyestervezel, nylonvezel en polypropyleenvezel. Verhelderen en ophelderen van polypropyleen plastic, harde PVC, ABS, EVA, polystyreen, polycarbonaat, enz. Het wordt toegevoegd aan de conventionele polymerisatie van polyester en nylon.<\/h4>\n\n\n\n

Om kunststoffen met verschillende eigenschappen uniform wit te maken, moet de fluorescerende witmaker zich niet alleen aanpassen aan de verwerkingsomstandigheden van de kunststof, maar ook voldoende moleculaire dispersie of volledige oplosbaarheid in de kunststof hebben. In kunststof kan het optische ophelderingseffect niet worden weergegeven of sterk worden verminderd. De selectie van de juiste modellen van verschillende materialen zal het ophelderende effect van de fluorescerende witmaker sterk verbeteren.<\/h4>\n\n\n\n

3. De molecuulformule van Optische witmaker OB is C26H26N2O2S, en de molecuulformule van Optische witmaker OB-1 is C28H18N2O2. In de bovenstaande afbeelding kunnen we duidelijk zien dat het twee totaal verschillende chemische stoffen zijn.<\/h4>\n\n\n\n

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

Welk product gebruikt Optische witmaker OB, welk product is meer geschikt voor Optische witmaker OB-1?<\/strong><\/h3>\n\n\n\n

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

Hoewel het twee verschillende chemische stoffen zijn, kun je aan de hand van de naamgeving ook raden dat er veel overeenkomsten zijn tussen de twee. Optische witmaker OB en Optische witmaker OB-1 hebben bijvoorbeeld een breed scala aan toepassingen. De meeste plastic ob en optische witmaker OB-1 kunnen samen worden gebruikt, en het witmakende en verhelderende effect is duidelijk. Dus, waar is het verschil?<\/h4>\n\n\n\n

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

1. Smeltpunt: Optische witmaker OB-1>Optische witmaker OB<\/h3>\n\n\n\n

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

Omdat het smeltpunt van optische witmaker OB 200 graden is, en het smeltpunt van optische witmaker OB-1 zelfs 360 graden is, bepaalt dit dat optische witmaker OB niet kan worden gebruikt voor plastic producten op hoge temperatuur, zoals behuizingen van airconditioners en sommige keukengereedschappen. Daarom, als uw product verwerking op hoge temperatuur vereist, is optische witmaker OB-1 uw eerste keuze.<\/h4>\n\n\n\n

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

2. Dispersie en stabiliteit: Optische witmaker OB>Optische witmaker OB-1<\/h3>\n\n\n\n

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

Hier moeten we eerst uitleggen dat een goede dispergeerbaarheid betekent dat het product gemakkelijker en gelijkmatig oplost. Verf en inkt stellen bijvoorbeeld hoge eisen aan de dispergeerbaarheid van de fluorescerende witmaker; goede stabiliteit betekent dat het product niet gemakkelijk migreert en in een later stadium vergeelt. Sommige inferieure schoenzolen waren bijvoorbeeld wit en schoon toen ze voor het eerst werden gekocht, maar ze werden geel en verkleurden na een tijdje, wat aantoont dat de stabiliteit van de fluorescerende witmaker slecht is.<\/h4>\n\n\n\n

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

Natuurlijk zeg ik niet dat de dispersie en stabiliteit van optische witmaker OB-1 niet goed is, maar het is iets slechter dan ob. Vanwege dit verschil raadt Lianda Fluorescentietechnologie over het algemeen niet aan om de optische witmaker OB-1 te gebruiken in inktcoatings en zachte kunststoffen. Ob is relatief beter in dispergeerbaarheid en weersbestendigheid, en het is niet gevoelig voor vergeling. De situatie van migratie.<\/h4>\n\n\n\n

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

De prijs is het grootste verschil tussen Optische witmaker<\/strong><\/strong> ob en optische witmaker OB-1<\/strong><\/h3>\n\n\n\n

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

In feite is het grootste verschil tussen Optische witmaker OB en Optische witmaker OB-1 de prijs. Ik herinner me dat 6 jaar geleden, de prijs van optische witmaker OB was vergelijkbaar met die van optische witmaker OB-1. Echter, vanwege China's landelijke milieubescherming rectificaties, de levering van grondstoffen van optische witmaker OB had problemen, zodat de prijs van optische witmaker OB omhooggeschoten. Optische witmaker OB is meer dan twee keer zo duur als optische witmaker OB-1. Volgens de schatting van Longchang chemische R & D-afdeling, kan het toenemen. Vanwege het enorme prijsverschil, moeten klanten die gebruik kunnen maken van de optische witmaker Optische witmaker OB-1 proberen te kiezen Optische witmaker OB-1. Degenen met speciale eisen, zoals high-end inkt coatings en zachte kunststoffen, worden aanbevolen om optische witmaker OB gebruiken.<\/h4>\n\n\n\n

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

Geconfronteerd met de stijgende prijs van optische witmaker OB, heeft de R & D-afdeling van Longchang Chemical bleef innoveren en speciale poetsmiddelen geschikt voor verschillende producten te vervangen optische witmaker OB, het verminderen van de kosten voor klanten, zoals ld- voor kleur masterbatches ontwikkeld. s01, ld-y01 voor speciale inkt op basis van olie coatings, enz.

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":"
