The best package is rarely the cheapest single grade.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>Le photo-initiateur est \u00e9galement un composant important de l'encre UV, qui d\u00e9termine le taux de photopolym\u00e9risation de l'encre UV. Le choix du photo-initiateur doit d'abord tenir compte du spectre d'absorption du photo-initiateur pour correspondre au spectre d'\u00e9mission de la source de lumi\u00e8re UV. La source de lumi\u00e8re UV est principalement utilis\u00e9e pour la lampe \u00e0 mercure \u00e0 moyenne pression, son spectre d'\u00e9mission dans la r\u00e9gion UV de 365nm, 313nm, 302nm, 254nm et d'autres longueurs d'onde a une forte intensit\u00e9 d'\u00e9mission, de nombreux photo-initiateurs dans les longueurs d'onde ci-dessus ont une grande absorption.<\/p>\n<p>L'encre UV est un syst\u00e8me color\u00e9 compos\u00e9 de pigments, car les pigments absorbent, r\u00e9fl\u00e9chissent et diffusent la lumi\u00e8re ultraviolette. Les diff\u00e9rentes couleurs de pigments n'ont pas la m\u00eame absorption et r\u00e9flexion de la lumi\u00e8re ultraviolette, ce qui affecte l'absorption de la lumi\u00e8re ultraviolette par le photo-initiateur de l'encre UV, et donc le taux de durcissement de la lumi\u00e8re de l'encre UV ; il est donc particuli\u00e8rement important d'utiliser le pigment qui absorbe les UV avec un impact minimal sur le photo-initiateur.<\/p>\n<p>L'absorption du pigment dans la r\u00e9gion UV de la plus petite zone de longueur d'onde, commun\u00e9ment appel\u00e9e la \"fen\u00eatre\" du pigment, cette zone de longueur d'onde est la plus travers\u00e9e par la lumi\u00e8re UV et l'absorption la plus favorable du photo-initiateur. Afin de tirer pleinement parti de l'effet synergique des diff\u00e9rents photo-initiateurs, les encres UV choisissent souvent plus de deux types de photo-initiateurs utilis\u00e9s conjointement, afin d'utiliser pleinement la source de lumi\u00e8re UV \u00e9mise par diff\u00e9rentes longueurs d'onde de la lumi\u00e8re UV et la \"fen\u00eatre\" du pigment pour assurer la transmission de la lumi\u00e8re UV, afin d'obtenir la quantit\u00e9 minimale de photo-initiateur, la vitesse de durcissement de la lumi\u00e8re de l'encre UV la plus rapide.<\/p>\n<p>Les photo-initiateurs couramment utilis\u00e9s pour les encres UV sont BP, 651, 1173, 184, MBF, ITX, 907, 369, TPO et 819. Il s'agit de photo-initiateurs de photopolym\u00e9risation \u00e0 radicaux libres, dont 651, 1173, 184, MBF, 907, 369, TPO et 819 sont des photo-initiateurs de craquage, BP et ITX \u00e9tant des photo-initiateurs de capture de l'hydrog\u00e8ne. .<\/p>\n<p>Il convient ici de souligner que l'encre blanche UV choisit g\u00e9n\u00e9ralement le TPO ou le 819 et le 184 avec l'utilisation du TPO et du 819 sont des photo-initiateurs \u00e0 base d'oxyde de phosphine acyle, l'activit\u00e9 photo-initiatrice est \u00e9lev\u00e9e, la longueur d'onde d'absorption UV est grande, il y a un effet de photoblanchiment, ce qui convient \u00e0 une vari\u00e9t\u00e9 de pigments pour le durcissement \u00e0 la lumi\u00e8re, en particulier le pigment blanc de dioxyde de titane. 184 est une classe de photo-initiateurs r\u00e9sistants au jaunissement, avec TPO et 819 avec l'utilisation d'un excellent durcissement de l'encre blanche UV. L'utilisation, le durcissement de l'encre blanche UV est excellent.<\/p>\n<p>En outre, le photo-initiateur m\u00e9thyl benzoylformate (MBF) est un photo-initiateur \u00e0 meilleure r\u00e9sistance au jaunissement, moins utilis\u00e9 dans le pass\u00e9, MBF et TPO ou 819 avec l'utilisation d'une encre blanche UV, son taux de durcissement \u00e0 la lumi\u00e8re et sa r\u00e9sistance au jaunissement sont meilleurs que la combinaison 184 et TPO ou 819, et conviennent donc particuli\u00e8rement \u00e0 la production d'encre UV blanche et d'encre UV de couleur claire. L'encre UV noire, dont le pigment est principalement du noir de carbone, absorbe presque enti\u00e8rement la lumi\u00e8re UV et doit \u00eatre utilis\u00e9e avec un syst\u00e8me photo-initi\u00e9 efficace. On estime actuellement que les combinaisons 369 et ITX avec TPO ou 819 sont les meilleures.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><a
