The best package is rarely the cheapest single grade.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>L'encre UV signifie que sous l'action de la lumi\u00e8re ultraviolette, les substances photosensibles du syst\u00e8me r\u00e9agissent chimiquement pour g\u00e9n\u00e9rer des fragments actifs, ce qui d\u00e9clenche la polym\u00e9risation et la r\u00e9ticulation des monom\u00e8res ou pr\u00e9polym\u00e8res actifs du syst\u00e8me, de sorte que le syst\u00e8me passe instantan\u00e9ment d'un vernis liquide \u00e0 un vernis solide.<\/p>\n<p>Composition de l'encre UV : Elle est principalement compos\u00e9e d'un pr\u00e9polym\u00e8re, d'un diluant r\u00e9actif, d'un photo-initiateur, d'un colorant organique et d'un auxiliaire.<\/p>\n<h2><strong>Quelle est la diff\u00e9rence entre l'encre UV et l'encre ordinaire ?<\/strong><\/h2>\n<p>L'encre UV est une encre sans solvant \u00e0 s\u00e9chage ultraviolet, son principe de s\u00e9chage est le m\u00eame que celui de l'huile \u00e0 lumi\u00e8re UV, les mat\u00e9riaux photosensibles re\u00e7oivent des photons ultraviolets pour d\u00e9clencher la r\u00e9action photochimique de polym\u00e9risation du pr\u00e9polym\u00e8re et du diluant. Son temps de r\u00e9action est tr\u00e8s court, environ 0,1-0,2S, la r\u00e9action apr\u00e8s la formation d'une couche de film d'encre durcissant sur la surface. Il n'y a pas de mati\u00e8re volatile ou perm\u00e9able pendant la r\u00e9action. Elle se caract\u00e9rise par une vitesse de s\u00e9chage rapide, une bonne brillance du film et une bonne r\u00e9sistance au frottement, mais le prix de l'encre UV est relativement \u00e9lev\u00e9.<\/p>\n<p>Le principe de s\u00e9chage de l'encre ordinaire est l'oxydation, la perm\u00e9ation, la volatilisation des solvants \u00e0 l'int\u00e9rieur de l'encre, ces diff\u00e9rents processus prennent plus de temps, avec l'encre offset ordinaire de la trame 90%, il faut pr\u00e8s de 20 heures pour s\u00e9cher.<\/p>\n<p>En r\u00e8gle g\u00e9n\u00e9rale, les presses \u00e0 papier \u00e0 plat n'utilisent pas de substrats adsorbants (tels que les surfaces en plastique PVC, les cartons dor\u00e9s et argent\u00e9s, les surfaces en acier, etc. ) lors de l'impression avec de l'encre UV. Comme ces mat\u00e9riaux sont imprim\u00e9s avec de l'encre ordinaire, la feuille d'encre pr\u00e9c\u00e9dente non s\u00e8che frottera le dos de la feuille suivante, ce qui endommagera l'impression.<\/p>\n<p>Traduit avec www.DeepL.com\/Translator (version gratuite)<\/p>\n<h2><strong>Quelles sont les applications des types d'encre d'impression UV utilis\u00e9s par les caract\u00e9ristiques ?<\/strong><\/h2>\n<p>1.
