Buyers usually compare a blended package instead of one isolated product.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>Die Aush\u00e4rtung der Beschichtung ist der Prozess, bei dem die Beschichtung auf das zu beschichtende Objekt aufgetragen wird und mit verschiedenen Mitteln einen trockenen Beschichtungsfilm (einschlie\u00dflich Hart- und Weichfilm) bildet.<\/p>\n<p>Die Faktoren, die die Aush\u00e4rtungsgeschwindigkeit beeinflussen, sind haupts\u00e4chlich die Art der Beschichtung, die Schichtdicke, die Aush\u00e4rtungsmethode, die Aush\u00e4rtungsbedingungen, die Aush\u00e4rtungsger\u00e4te und die spezifischen Aush\u00e4rtungsprotokolle usw.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>(1) Art der Beschichtung<\/strong><\/h2>\n<p>Unter den gleichen Aush\u00e4rtungsbedingungen variiert die Aush\u00e4rtungsgeschwindigkeit der verschiedenen Lacke stark. Allgemein gesprochen, fl\u00fcchtige Farbe Aush\u00e4rtung schnell, \u00d6l-basierte Farbe Aush\u00e4rtung langsam, polymere Farbe ist sehr unterschiedlich, polymere Farbe in der lichtempfindlichen Farbe Aush\u00e4rtung am schnellsten, w\u00e4hrend andere polymere Farbe ist mehr zwischen fl\u00fcchtigen Farbe und \u00d6l-basierte Farbe, bei der Verwendung von mechanisierten Flie\u00dfband f\u00fcr die Endbearbeitung, fl\u00fcchtige Farbe, S\u00e4ure-h\u00e4rtende Amino-Alkyd-Farbe ist h\u00e4ufiger verwendet.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>(2) Dicke der Beschichtung<\/strong><\/h2>\n<p>Im Veredelungsprozess wird die Beschichtung grunds\u00e4tzlich nicht auf einmal gebildet, sondern in der Regel durch mehrere d\u00fcnne Schichten (z. B. \u00d6llack wird in der Regel einmal etwa 35\u03bcm aufgetragen, Nitrocelluloselack etwa 15\u03bcm, usw.). Unter den gleichen Aush\u00e4rtungsbedingungen, die d\u00fcnne Beschichtung bei der Aush\u00e4rtung, die innere Spannung ist klein, die Bildung von weniger Beschichtungsdefekte; w\u00e4hrend die Beschichtung zu dick ist, ist die innere Spannung gr\u00f6\u00dfer, leicht zu Falten und andere Defekte zu produzieren, w\u00e4hrend aufgrund der Verdampfung von L\u00f6sungsmittel, die Beschichtung Schrumpfung, was zu ungleichm\u00e4\u00dfigen Glanz, interne Nicht-H\u00e4rtung, etc. In der Praxis hat sich gezeigt, dass zus\u00e4tzlich zu Polyesterlack die physikalischen Eigenschaften des durch mehrere Schichten gebildeten Lackfilms besser sind als die gleiche Dicke des durch eine Schicht gebildeten Lackfilms.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>(3) Aush\u00e4rtungsbedingungen<\/strong><\/h2>\n<p>1- Aush\u00e4rtungstemperatur Die Aush\u00e4rtungstemperatur hat einen entscheidenden Einfluss auf die Aush\u00e4rtungsgeschwindigkeit der meisten Farbbeschichtungen. Wenn die Aush\u00e4rtungstemperatur zu niedrig ist, sind die L\u00f6sungsmittelverdampfung und die chemische Reaktion tr\u00e4ge, und die Beschichtung kann nur schwer ausgeh\u00e4rtet werden. Eine Erh\u00f6hung der Temperatur kann die L\u00f6sungsmittelverdampfung und die Wasserverdampfung beschleunigen, die Oxidationsreaktion und die thermochemische Reaktion der Beschichtung beschleunigen, und die Aush\u00e4rtungsgeschwindigkeit der Beschichtung wird beschleunigt, aber die Temperatur kann nicht unbegrenzt erh\u00f6ht werden, weil die Temperatur und die Aush\u00e4rtungsgeschwindigkeit nicht proportional zueinander sind, wenn die Aush\u00e4rtungstemperatur zu hoch ist, wird die Aush\u00e4rtungsgeschwindigkeit nicht wesentlich erh\u00f6ht, aber der Lackfilm wird vergilbt oder Nicht nur, dass die Temperatur in den Prozess der Aush\u00e4rtung der Beschichtung hat auch einen Einfluss auf das Substrat, das Substrat erhitzt wird, was zu Ver\u00e4nderungen im Feuchtigkeitsgehalt, das Substrat Schrumpfung und Verformung, und sogar Verziehen, Rissbildung, fl\u00fcchtige Lackschicht, Aush\u00e4rtungstemperatur \u00fcbersteigt 60 \u2103, das L\u00f6sungsmittel verdampft heftig, die Oberfl\u00e4chenschicht schnell trocken fest, die interne L\u00f6sungsmittel Dampf erreicht die Oberfl\u00e4chenschicht ist einfach, Blasen zu produzieren, so dass bei der Verwendung von k\u00fcnstlichen Aush\u00e4rtung Methoden, die Oberfl\u00e4chentemperatur ist in der Regel nicht mehr als 60\u2103.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Die Aush\u00e4rtung von Lacken erfolgt durch die folgenden drei allgemein verwendeten Methoden<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>I.

control yellowing or lamp fit well while another improves cure depth or line-speed performance, so the full package is often stronger than any single grade.<\/p>\n<p><strong>Should incomplete cure always be solved by adding more initiator?<\/strong><br \/>Not automatically. The real limitation may be the lamp, film thickness, pigment shading, or the rest of the reactive system rather than simple under-dosage.<\/p>\n<p><!-- lc-commercial-end --><\/p>\n<h2><strong><b>Kontaktieren Sie uns jetzt!<\/b><\/strong><\/h2>\n<h4><strong><b>Wenn Sie COA, MSDS oder TDS von UV-Photoinitiator ben\u00f6tigen, geben Sie bitte Ihre Kontaktinformationen in das untenstehende Formular ein.
