The best package is rarely the cheapest single grade.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>Inchiostro UV significa che sotto l'azione della luce ultravioletta, le sostanze fotosensibili del sistema reagiscono chimicamente per generare frammenti attivi, che innescano la polimerizzazione e la reticolazione dei monomeri o dei prepolimeri attivi del sistema, in modo che il sistema si trasformi istantaneamente da rivestimento liquido a rivestimento solido.<\/p>\n<p>Composizione dell'inchiostro UV: \u00c8 composto principalmente da prepolimero, diluente reattivo, fotoiniziatore, colorante organico e ausiliario.<\/p>\n<h2><strong>Qual \u00e8 la differenza tra l'inchiostro UV e l'inchiostro comune?<\/strong><\/h2>\n<p>L'inchiostro UV \u00e8 un inchiostro privo di solventi a polimerizzazione ultravioletta; il suo principio di essiccazione \u00e8 lo stesso dell'olio a luce UV, i materiali fotosensibili ricevono fotoni ultravioletti per innescare la reazione fotochimica di polimerizzazione del prepolimero e del diluente. Il tempo di reazione \u00e8 molto breve, circa 0,1-0,2S, e la reazione avviene dopo la formazione dello strato di pellicola di inchiostro indurente sulla superficie. Non c'\u00e8 materiale volatile o permeabile durante la reazione. Caratterizzato da una rapida velocit\u00e0 di essiccazione, buona brillantezza del film, resistenza all'attrito, il prezzo dell'inchiostro UV \u00e8 relativamente alto.<\/p>\n<p>Il principio di essiccazione dell'inchiostro ordinario \u00e8 l'ossidazione, la permeazione e la volatilizzazione del solvente all'interno dell'inchiostro; questi diversi processi richiedono tempi pi\u00f9 lunghi; con la stampa dell'inchiostro offset ordinario su schermo 90% sono necessarie quasi 20 ore per l'essiccazione.<\/p>\n<p>Generalmente la stampa su macchine da stampa piane non prevede l'utilizzo di substrati adsorbenti (come superfici plastiche in PVC, cartone dorato e argentato, superfici in acciaio, ecc. Poich\u00e9 questi materiali, se stampati con inchiostro ordinario, il foglio precedente non asciutto sfregher\u00e0 il retro del foglio successivo danneggiando la stampa.<\/p>\n<p>Tradotto con www.DeepL.com\/Translator (versione gratuita)<\/p>\n<h2><strong>Quali sono le applicazioni dei tipi di inchiostro da stampa UV utilizzati per le caratteristiche?<\/strong><\/h2>\n<p>1. Inchiostro uv duro, generalmente utilizzato in fogli;<br \/>\n2. L'inchiostro uv morbido viene generalmente utilizzato su materiali morbidi;<br \/>\n3. L'inchiostro uv neutro viene generalmente utilizzato su materiali moderatamente morbidi e duri.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Alcuni clienti di pannelli in PVC espanso affermano che \u00e8 facile che si stacchino dopo la stampa. Lo stesso pannello non presenta problemi quando lo riprendiamo e lo colpiamo. \u00c8 un problema di inchiostro utilizzato per la stampa UV?<\/strong><\/h2>\n<p>Il disegno del PVC si stacca: per prima cosa verificare la causa dell'inchiostro uv stesso, dopo la stampa, toccare se \u00e8 completamente asciutto, se non lo \u00e8, aumentare la potenza della lampada a led; in secondo luogo, sostituire l'inchiostro uv, si consiglia di utilizzare l'inchiostro uv duro, che \u00e8 pi\u00f9 adatto per i materiali in pvc; infine, la plastica pu\u00f2 essere utilizzata Coating, pulire una volta prima della stampa.<\/p>\n<h2><strong>Come rimuovere l'inchiostro UV dopo la polimerizzazione?<\/strong><\/h2>\n<p>1. Utilizzare un disossidante chimico per rimuovere e controllare se l'inchiostro \u00e8 completamente indurito. Prima si usa il solvente, meglio si pulisce.<\/p>\n<p>2. Se l'inchiostro \u00e8 completamente polimerizzato, lasciar cadere il solvente sul punto in cui l'inchiostro deve essere rimosso e attendere 24 o 48 ore per rimuoverlo.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Formulazione dell'inchiostro UV<\/strong><\/h2>\n<h3><strong>1. Il pigmento<\/strong><\/h3>\n<p>lTipo:<\/p>\n<p>I pigmenti organici (ftalocianina, azo) sono ricchi di colore, brillanti e di buona qualit\u00e0;<\/p>\n<p>I pigmenti inorganici (biossido di titanio, nerofumo) sono resistenti alla luce, al calore, ai solventi e poco costosi;<\/p>\n<p>l Impatto sulle prestazioni: La quantit\u00e0 di pigmento aggiunta al sistema \u00e8 di 5-20%. Secondo la legge di Lambert Beer, quando al sistema vengono aggiunti pigmenti che assorbono la luce, la quantit\u00e0 totale di fotoni assorbiti dal fotoiniziatore diminuisce.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>2.
