L'encre luminescente g\u00e9n\u00e9rale est constitu\u00e9e d'une encre durcissant \u00e0 chaud dop\u00e9e avec des mat\u00e9riaux luminescents, et les produits luminescents sont pr\u00e9par\u00e9s par durcissement \u00e0 chaud, ce qui est difficile \u00e0 utiliser dans l'encre UV, qui est d\u00e9termin\u00e9e par les caract\u00e9ristiques sp\u00e9ciales des mat\u00e9riaux luminescents. Les mat\u00e9riaux luminescents \u00e0 longue r\u00e9manence sont des poudres inorganiques d'une taille de 10 \u00e0 60\u03bcm. Dans des conditions sp\u00e9ciales et avec des particules encore plus grosses, ces poudres ont une certaine couleur et sont opaques ; dans la pratique, il faut imprimer une certaine \u00e9paisseur pour obtenir un meilleur effet d'\u00e9mission de lumi\u00e8re.<\/p>\n<p>La poudre luminescente dans l'encre est une m\u00e9thode courante de pr\u00e9paration des encres luminescentes. Dans le pass\u00e9, les encres luminescentes \u00e9taient pr\u00e9par\u00e9es \u00e0 partir d'un m\u00e9lange d'encre thermodurcissable et de poudre luminescente. Avec le d\u00e9veloppement de la technologie UV, la combinaison de la poudre luminescente et de l'encre UV pour pr\u00e9parer l'encre luminescente UV a \u00e9t\u00e9 progressivement adopt\u00e9e par la majorit\u00e9 des fabricants d'imprimantes, en particulier pour la production de signes lumineux avec l'encre luminescente UV au lieu de l'encre luminescente thermodurcissable, qui pr\u00e9sente des avantages consid\u00e9rables. L'impression d'encre lumineuse UV par la technologie de s\u00e9rigraphie est une m\u00e9thode courante de pr\u00e9paration des enseignes lumineuses.<\/p>\n<p>\u2460 S\u00e9lection de la poudre lumineuse : L'encre luminescente UV doit tenir compte de la s\u00e9lection de la poudre luminescente dans la s\u00e9rigraphie, l'exigence de base de la poudre luminescente est une luminosit\u00e9 \u00e9lev\u00e9e et une taille de particule mod\u00e9r\u00e9e. Les particules de grande taille ne peuvent pas \u00eatre manqu\u00e9es par l'\u00e9cran, l'\u00e9paisseur d'impression de petite taille n'est pas suffisante, vous devez augmenter le nombre d'impressions pour atteindre les exigences d'\u00e9paisseur, le travail et le temps, utiliser g\u00e9n\u00e9ralement 50 ~ 80\u03bcm de la poudre luminescente est plus appropri\u00e9. La poudre luminescente de terre rare est jaune-vert clair, donc choisir de faire le substrat de signalisation au bleu ou au vert est appropri\u00e9.<\/p>\n<p>\u2461 production de pochoirs. Les enseignes lumineuses n\u00e9cessitent g\u00e9n\u00e9ralement une couche lumineuse imprim\u00e9e plus \u00e9paisse, de sorte que l'\u00e9cran habituel en polyester monofilament de 80 mesh, de sorte que la poudre lumineuse puisse passer \u00e0 travers l'\u00e9cran, tout en imprimant la couche lumineuse, est \u00e9galement plus \u00e9paisse. En ce qui concerne la plaque, il convient de tenir compte des produits de signalisation g\u00e9n\u00e9rale, tels que certains panneaux de noms de lieux, pour lesquels le m\u00eame motif ne sera pas imprim\u00e9 plusieurs fois de suite ; dans ce cas, vous pouvez choisir un photopolym\u00e8re r\u00e9sistant \u00e0 l'huile de qualit\u00e9 inf\u00e9rieure, ce qui permet d'\u00e9conomiser des co\u00fbts.<\/p>\n<p>\u2462 appr\u00eat pr\u00e9-couch\u00e9. Lors de l'impression de la couche luminescente avant l'impression d'un substrat blanc, la couche luminescente est imprim\u00e9e sur le substrat blanc. L'impression de la couche de substrat est l'une des \u00e9tapes n\u00e9cessaires \u00e0 l'impression de l'encre luminescente, le pr\u00e9-rev\u00eatement de la surface du substrat contribuera \u00e0 am\u00e9liorer la performance luminescente de l'encre luminescente. L'utilisation de diff\u00e9rents pigments de la couche de substrat sur la performance lumineuse de l'encre n'est pas la m\u00eame, l'ajout d'une couche de substrat blanc en dioxyde de titane est le plus propice \u00e0 l'am\u00e9lioration de la performance lumineuse des encres luminescentes, car la couche de substrat blanc peut rendre la lumi\u00e8re incidente ainsi que la fluorescence \u00e9mise plus pleinement r\u00e9fl\u00e9chies \u00e0 travers la couche d'encre, maximisant ainsi le r\u00f4le des encres luminescentes.<\/p>\n<p>Il convient de noter que l'encre lumineuse UV doit avoir une bonne adh\u00e9rence sur le substrat blanc, sinon la couche d'encre lumineuse se d\u00e9tachera facilement apr\u00e8s le durcissement. L'encre PVC blanche est g\u00e9n\u00e9ralement utilis\u00e9e parce que la plupart des encres UV ont une bonne adh\u00e9rence sur la couche d'encre PVC, ce qui \u00e9vite le ph\u00e9nom\u00e8ne de d\u00e9tachement de la couche lumineuse de la signal\u00e9tique.<\/p>\n<p>\u2463 Veillez \u00e0 l'adh\u00e9rence entre les couches lors de l'impression et du s\u00e9chage \u00e0 plusieurs reprises. L'utilisation de l'encre UV doit tenir compte d'un point tr\u00e8s important : la production d'enseignes n\u00e9cessite souvent que la couche lumineuse atteigne une certaine \u00e9paisseur, ce qui requiert plusieurs impressions pour r\u00e9pondre aux exigences d'\u00e9paisseur. Comme l'encre UV est imprim\u00e9e une fois imm\u00e9diatement apr\u00e8s le durcissement, la surface durcie est lisse, l'impression suivante est effectu\u00e9e sur la base de la couche pr\u00e9c\u00e9dente, cette fois l'encre UV doit avoir une bonne adh\u00e9rence entre chaque couche, ce qui emp\u00eache le ph\u00e9nom\u00e8ne de d\u00e9lamination. Par cons\u00e9quent, lors de la s\u00e9lection de l'encre UV, il convient d'accorder une attention particuli\u00e8re au probl\u00e8me de l'adh\u00e9rence entre les couches.<\/p>\n<p>Les mat\u00e9riaux \u00e9lectroluminescents \u00e0 longue r\u00e9manence et les encres UV utilis\u00e9s en combinaison avec l'impression doivent tenir compte des points suivants.<\/p>\n<p>\u2460 long afterglow light-emitting material is a kind of inorganic powder material, light-emitting material density is easy to precipitate, so you need to stir before use, at same time, light-emitting material is easy to react with rust, heavy metals, etc., so it is not appropriate to use metal rods in the dispersing and grinding process, and it is not suitable to be stored in metal containers, otherwise it will lead to the material to become black, affecting the effect of the use of the material. Le choix des r\u00e9cipients est appropri\u00e9 : verre, c\u00e9ramique, rev\u00eatement en \u00e9mail, r\u00e9cipients en plastique.<\/p>\n<p>\u2461 L'encre luminescente est transform\u00e9e en film, la fonction d'absorption de la lumi\u00e8re est r\u00e9alis\u00e9e par les particules de mat\u00e9riaux \u00e9lectroluminescents. En raison des exigences de la lumi\u00e8re \u00e0 travers les mat\u00e9riaux \u00e9lectroluminescents li\u00e9s ensemble dans la r\u00e9sine, la transmission de la lumi\u00e8re doit \u00eatre bonne, sans pouvoir masquant, de sorte que la s\u00e9lection de la r\u00e9sine, du vernis doit \u00eatre incolore ou d'une transparence claire.<\/p>\n<p>\u2462 Plus la teneur en mat\u00e9riau luminescent est \u00e9lev\u00e9e, plus la luminosit\u00e9 est forte, mais pour que le mat\u00e9riau luminescent adh\u00e8re correctement aux produits rev\u00eatus, la proportion de r\u00e9sine ne doit pas \u00eatre inf\u00e9rieure \u00e0 10% au minimum. Bien entendu, plus la proportion de r\u00e9sine est \u00e9lev\u00e9e, plus le rev\u00eatement luminescent est lisse et bien fini. Par cons\u00e9quent, le dosage de la mati\u00e8re luminescente est g\u00e9n\u00e9ralement de 20%-60% de la masse totale ou de 10%-35% du volume, ou le dosage de la mati\u00e8re luminescente est d\u00e9termin\u00e9 en fonction de l'exigence de luminosit\u00e9.<\/p>\n<p>\u2463UV Encre luminescente en s\u00e9rigraphie \u00e0 consid\u00e9rer le choix des mat\u00e9riaux luminescents, mat\u00e9riaux luminescents, les exigences de base de la haute luminosit\u00e9, la taille des particules mod\u00e9r\u00e9e. La taille des particules ne peut pas fuir l'\u00e9cran, la taille des particules de petite \u00e9paisseur d'impression n'est pas suffisante, il faut augmenter le nombre d'impressions pour atteindre les exigences d'\u00e9paisseur, la perte de temps, l'utilisation de 20 ~ 80\u03bcm de poudre luminescente est plus appropri\u00e9e. Les mat\u00e9riaux luminescents sont plus color\u00e9s, la production de produits de signalisation choisit g\u00e9n\u00e9ralement des mat\u00e9riaux luminescents jaune-vert clair.<\/p>\n<p>\u2464 Processus de production, les mat\u00e9riaux \u00e9lectroluminescents ne peuvent pas \u00eatre broy\u00e9s, ne peuvent pas utiliser le broyeur \u00e0 trois rouleaux, la pr\u00e9paration de l'encre \u00e9lectroluminescente ne peut se faire qu'\u00e0 l'aide d'un disperseur ou d'un m\u00e9langeur \u00e0 grande vitesse. La m\u00e9thode sp\u00e9cifique consiste \u00e0 mettre la r\u00e9sine ou le vernis dans le r\u00e9cipient, \u00e0 ajouter des additifs, \u00e0 mettre en marche l'agitateur, \u00e0 ajouter l'agent anti-coulant, \u00e0 agiter lentement les mat\u00e9riaux \u00e9lectroluminescents \u00e0 leur tour. Apr\u00e8s avoir ajout\u00e9 la mati\u00e8re lumineuse, augmenter la vitesse jusqu'\u00e0 ce que la mati\u00e8re lumineuse soit uniform\u00e9ment dispers\u00e9e dans le mat\u00e9riau, puis filtrer pour obtenir le produit.<\/p>\n<p>\u2465 Les compos\u00e9s de m\u00e9taux lourds ne doivent pas \u00eatre utilis\u00e9s comme additifs.<\/p>\n<p>Faites attention au choix de la taille des mailles. Les mat\u00e9riaux \u00e9mettant de la lumi\u00e8re en g\u00e9n\u00e9ral, en raison de la taille plus importante des particules, n\u00e9cessitent un tamis de plus petite taille ; il est g\u00e9n\u00e9ralement pr\u00e9f\u00e9rable d'utiliser un tamis de 100 mesh. Le degr\u00e9 de durcissement du produit apr\u00e8s l'impression a \u00e9galement un impact sur la qualit\u00e9 finale du produit ; il est possible de v\u00e9rifier si le durcissement est complet de quatre mani\u00e8res diff\u00e9rentes. Premi\u00e8rement, le test de duret\u00e9 du crayon, g\u00e9n\u00e9ralement de 3 ~ 4H, peut \u00eatre consid\u00e9r\u00e9 comme une encre compl\u00e8tement durcie. Deuxi\u00e8mement, on teste la m\u00e9thode de chute du solvant, mais aussi la r\u00e9sistance au solvant, l'acide propionique tombe sur la surface de l'impression apr\u00e8s 20 minutes et ne subit aucun changement, ce qui prouve que l'encre a \u00e9t\u00e9 compl\u00e8tement durcie. Troisi\u00e8mement, le test de la m\u00e9thode de compression, c'est-\u00e0-dire la fibre de coton plac\u00e9e sur la surface de l'impression, avec un fond lisse, des poids de 500g press\u00e9s sur la surface de la fibre de coton pendant 2 ~ 3min, puis enlever les poids, si la fibre de coton ne colle pas \u00e0 la surface de l'impression pour prouver qu'il a \u00e9t\u00e9 compl\u00e8tement durci. Quatri\u00e8mement, la m\u00e9thode de test de la grille, l'utilisation de la force de la grille dans la surface de l'impression en croix, puis l'utilisation du ruban adh\u00e9sif pour coller \u00e0 la surface de la croix, s'il n'y a pas d'encre collante, ce qui indique que le durcissement est complet et que l'adh\u00e9rence de la couche d'encre apr\u00e8s le durcissement est relativement bonne.<\/p>\n<p>&nbsp;<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>A practical selection route for photoinitiator-related projects<\/h2>\n<p>When technical buyers or formulators 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 the benchmark:<\/strong> pigment load, monomer package, and film thickness can all change the apparent ranking of the same initiator.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-tpo-l-cas-84434-11-7\/\">CHLUMINIT TPO-L<\/a>:<\/strong> A strong low-yellowing reference for LED-oriented UV systems.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-819-irgacure-819-cas-162881-26-7\/\">CHLUMINIT 819<\/a>:<\/strong> Useful when a formulation needs stronger absorption and deeper cure support.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/cas-270586-78-2\/\">CHLUMINIT TMO<\/a>:<\/strong> A valuable comparison point when lower yellowing or TPO-replacement discussions matter.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/photoinitiator-184-cas-947-19-3\/\">CHLUMINIT 184<\/a>:<\/strong> A classic free-radical benchmark for fast surface cure in many UV systems.<\/li>\n<\/ul>\n<h3>FAQ for buyers and formulators<\/h3>\n<p><strong>Why are blended photoinitiator packages so common?<\/strong><br \/>Because one product may 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.
