The best package is rarely the cheapest single grade.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>Das Hauptmerkmal von UV-Pulverbeschichtungen besteht darin, dass der Prozess in zwei unterschiedliche Phasen unterteilt ist, wobei w\u00e4hrend der Schmelzspachtelungsphase keine fr\u00fche Aush\u00e4rtung des Harzes stattfindet, so dass ausreichend Zeit zur Verf\u00fcgung steht, damit sich die Beschichtung vollst\u00e4ndig nivellieren und Luftblasen aussto\u00dfen kann; durch den Einsatz der UV-H\u00e4rtungstechnologie k\u00f6nnen die Temperaturen des Erw\u00e4rmungs- und Aush\u00e4rtungsprozesses erheblich gesenkt und die Produktionseffizienz verbessert werden. Durch den Einsatz der UV-H\u00e4rtungstechnologie wird die Temperatur des Aufheiz- und Aush\u00e4rtungsprozesses erheblich gesenkt, was die Produktivit\u00e4t erh\u00f6ht und UV-Beschichtungen f\u00fcr alle Arten von w\u00e4rmeempfindlichen Substraten geeignet macht.<\/p>\n<p>Im Vergleich zu UV-geh\u00e4rteten Fl\u00fcssiglacken haben lichtgeh\u00e4rtete Pulverlacke keine aktive Verd\u00fcnnung, eine geringe Filmschrumpfung und eine hohe Haftung auf dem Substrat. Lichth\u00e4rtende Pulverlacke k\u00f6nnen in einer Schicht aufgetragen werden und bilden eine Beschichtung von hervorragender Qualit\u00e4t mit einer Dicke von 75~125\u03bcm. Daher sind lichth\u00e4rtende Pulverlacke auch l\u00f6sungsmittelfrei und umweltfreundlich und haben gr\u00f6\u00dfere technische, wirtschaftliche und \u00f6kologische Vorteile als duroplastische Pulverlacke und UV-Fl\u00fcssiglacke.<\/p>\n<p>Lichth\u00e4rtende Pulverbeschichtungen bestehen aus einem Hauptharz, einem Photoinitiator, Pigmenten, F\u00fcllstoffen, verschiedenen Additiven und so weiter. Das Hauptharz ist die wichtigste filmbildende Substanz von lichth\u00e4rtenden Pulverbeschichtungen und ist die Hauptkomponente, die die Beschaffenheit der Beschichtung und die Leistung des Beschichtungsfilms bestimmt. Formulierung von lichth\u00e4rtenden Pulverbeschichtungen, auf der einen Seite, das Harz ist erforderlich, um das Pulver gute Lagerstabilit\u00e4t zu geben, auf der anderen Seite, die verwendeten Rohstoffe m\u00fcssen bei einer niedrigeren Temperatur (wie 100 \u2103 unter) mit der erforderlichen Schmelzviskosit\u00e4t, um sicherzustellen, dass die Beschichtung in der Lichth\u00e4rtung vor und Lichth\u00e4rtung Prozess mit guten Fluss und Nivellierung Eigenschaften, gefolgt von Lichth\u00e4rtung Reaktion unter 120 \u2103. Die wichtigsten Harze, die entwickelt wurden, sind im Allgemeinen unges\u00e4ttigte Polyester, Vinyletherharze, unges\u00e4ttigte Polyesteracrylate, Urethanacrylate, Epoxidharze usw.<\/p>\n<p>Der Zusatz von hyperverzweigten Harzen kann die Glas\u00fcbergangstemperatur des Harzes herabsetzen, was zu einer Verbesserung der rheologischen Eigenschaften und der Leistung des Beschichtungsfilms f\u00fchrt. Hyperverzweigte Polymere haben eine hohe Funktionalit\u00e4t, sph\u00e4risch symmetrische dreidimensionale Struktur und inter- und intramolekulare Strukturmerkmale wie Kettenverschr\u00e4nkung, niedrige Viskosit\u00e4t, gute Zwischenl\u00f6slichkeit, hohe Aktivit\u00e4t, und es ist einfach, die Oberfl\u00e4che von mehreren funktionellen Gruppen und andere Merkmale zu \u00e4ndern, k\u00f6nnen in Beschichtungen als filmbildende Substanzen, Viskosit\u00e4tsmodifikatoren, etc. verwendet werden, um die Leistung des Beschichtungsfilms zu verbessern.<\/p>\n<p>Der Initiator kann aus einer breiten Palette von Arten, wie die Verwendung von \u03b1-Hydroxyketon (AHK) und Doppel-Acyl-Phosphin-Oxid (BAPO) Kombination, AHK wegen seiner Unempfindlichkeit gegen\u00fcber Sauerstoff-Blockierung und die daraus resultierende Beschichtung hat gute Oberfl\u00e4cheneigenschaften ausgew\u00e4hlt werden, und in seiner Struktur der Benzolring Substituent auf der gegen\u00fcberliegenden Seite eines polaren Hydroxy-Ethyl-Sauerstoff-Substituenten und machen die Verbindung in UV-h\u00e4rtbaren Pulverbeschichtungen Extrusion und Filmbildung Temperatur unter der geringen Fl\u00fcchtigkeit. BAPO hat zwei signifikante Absorptionsspitzen bei etwa 370nm und 400~450nm, mit hoher Photoreaktivit\u00e4t und Absorptionseigenschaften, kann die Bed\u00fcrfnisse der tiefen Aush\u00e4rtung erf\u00fcllen; kationische Aush\u00e4rtung System kann Sulfoniumsalz, Jodoniumsalz, etc. verwendet werden.<\/p>\n<h2><strong><a

screen photoinitiators, the most useful decision frame is usually cure quality plus application fit: which package cures reliably, keeps appearance acceptable, and still works under the lamp, film thickness, and substrate conditions of the actual process.<\/p>\n<ul>\n<li><strong>Match the package to the lamp first:<\/strong> mercury lamps, UV LEDs, and visible-light systems can rank the same photoinitiators very differently.<\/li>\n<li><strong>Check depth cure and surface cure separately:<\/strong> a film that feels dry on top can still be weak underneath.<\/li>\n<li><strong>Balance yellowing with reactivity:<\/strong> the strongest deep-cure route is not always the best commercial choice if color or migration risk becomes unacceptable.<\/li>\n<li><strong>Use the final formula as
