No entanto, durante a polimeriza\u00e7\u00e3o de radical livre, a dist\u00e2ncia entre os mon\u00f4meros ou olig\u00f4meros muda da dist\u00e2ncia da a\u00e7\u00e3o da for\u00e7a de van der Waals antes da cura para a dist\u00e2ncia da a\u00e7\u00e3o da liga\u00e7\u00e3o covalente ap\u00f3s a cura, e a dist\u00e2ncia entre os dois encolhe, de modo que o encolhimento do volume \u00e9 \u00f3bvio. Juntamente com o tempo de cura muito curto, a camada de tinta da tens\u00e3o residual interna \u00e9 muito grande, portanto, em compara\u00e7\u00e3o com a tinta geral \u00e0 base de solvente, a tinta offset UV tende a deteriorar a ades\u00e3o.<\/p>\n<p>Atualmente, para alguns substratos pl\u00e1sticos especiais (como PE, PP e parte do PET), a tinta offset UV n\u00e3o pode proporcionar uma boa ades\u00e3o, principalmente porque esses materiais t\u00eam diluente ativo que n\u00e3o pode ser dissolvido, caracter\u00edsticas de baixa polaridade de superf\u00edcie, foi curado entre o filme de tinta e o substrato n\u00e3o pode formar uma for\u00e7a efetiva, resultando em uma ades\u00e3o ruim. A solu\u00e7\u00e3o do problema de ades\u00e3o da tinta offset UV a esses pl\u00e1sticos \u00e9 um problema t\u00e9cnico insuper\u00e1vel no setor. De acordo com a experi\u00eancia pr\u00e1tica, para resolver o problema de ader\u00eancia da tinta offset UV em substratos dif\u00edceis, geralmente s\u00e3o considerados os seguintes aspectos: \u2460 Aumentar o diluente ativo com baixa tens\u00e3o superficial para melhorar a molhabilidade da tinta no substrato. \u2461 Selecionar o diluente ativo e o olig\u00f4mero de baixa funcionalidade para reduzir a tens\u00e3o da tinta e o encolhimento do volume. \u2462 Selecione o olig\u00f4mero com alto peso molecular e baixa Tg. \u2463 Use olig\u00f4mero modificado por grupo funcional especial, como acrilato de poli\u00e9ster clorado. \u2464 Adicione um promotor de ades\u00e3o.<\/p>\n<p>No entanto, esse tratamento geralmente leva a um desempenho de cura ruim da tinta e \u00e0 deteriora\u00e7\u00e3o da capacidade de impress\u00e3o. Com base na situa\u00e7\u00e3o da aplica\u00e7\u00e3o, \u00e9 muito dif\u00edcil fazer com que a tinta offset UV tenha um bom desempenho de ades\u00e3o a todos os substratos, portanto, ao mesmo tempo em que se melhora o desempenho da tinta, tamb\u00e9m \u00e9 necess\u00e1rio realizar o pr\u00e9-tratamento da superf\u00edcie do substrato (como tratamento corona, tratamento com chama) ou aumentar a viscosidade do revestimento prim\u00e1rio, etc., para melhorar o desempenho da superf\u00edcie do substrato. Em suma, isso deve ser combinado com o processo de impress\u00e3o para resolver o problema da tinta offset UV para as dificuldades de ades\u00e3o do substrato.<\/p>\n<p>O uso da tinta offset UV tamb\u00e9m requer aten\u00e7\u00e3o \u00e0s seguintes quest\u00f5es.<\/p>\n<p>(1) Placa de impress\u00e3o<br \/>\nA impress\u00e3o offset pode usar chapas PS positivas e negativas. No caso de uma chapa PS do tipo positivo, deve-se usar uma chapa PS do tipo positivo especializada em tinta UV, pois os diluentes ativos e os fotoiniciadores podem decompor os pontos da chapa PS comum, resultando em uma diminui\u00e7\u00e3o da resist\u00eancia de impress\u00e3o da chapa de impress\u00e3o. Se voc\u00ea usar uma chapa PS geral do tipo positivo, precisar\u00e1 assar a chapa, ou seja, de acordo com o m\u00e9todo convencional de chapa PS comum feita ao sol, voc\u00ea precisar\u00e1 assar a chapa por 10 a 15 minutos (temperatura de 250 \u2103).<\/p>\n<p>(2) Rolos e mantas de borracha<br \/>\nPara usar rolos especiais UV, o uso de tinta \u00e0 base de \u00f3leo e rolos do tipo tinta UV tamb\u00e9m pode ser usado para seu efeito. A sele\u00e7\u00e3o da manta de tinta geral \u00e0 base de \u00f3leo e da tinta UV com a manta pode ser feita, mas, devido \u00e0 tinta UV no diluente ativo, o processo de impress\u00e3o nos rolos e nas mantas comuns penetrar\u00e1, por um lado, resultando em uma redu\u00e7\u00e3o do diluente ativo na tinta, destruindo a fluidez da tinta; por outro lado, resultando na corros\u00e3o dos rolos e das mantas, a curto prazo, a superf\u00edcie dos rolos e das mantas de borracha e a expans\u00e3o da deforma\u00e7\u00e3o da superf\u00edcie do vidro, a impress\u00e3o a longo prazo dos rolos e das mantas. A longo prazo, os rolos de impress\u00e3o e a superf\u00edcie da manta apresentar\u00e3o descascamento ou rachaduras localizadas. Portanto, geralmente escolhemos borracha EPDM (borracha EPDM) ou borracha de silicone feita de rolos de borracha, a melhor dureza em 40SH de Shaw ou mais. Selecione a manta de borracha especial UV, a mistura da manta de borracha para adicionar componentes de resina anti-UV, a radia\u00e7\u00e3o UV pode ser resistente \u00e0 manta de borracha e n\u00e3o \u00e9 f\u00e1cil de pulverizar. Ou use uma manta autoadesiva UV, a manta tamb\u00e9m cont\u00e9m componentes de resina anti-UV, para impress\u00e3o UV, e a vida \u00fatil pode ser estendida.<\/p>\n<p>(3) Dispersar e moer<br \/>\nO pigmento de tinta de impress\u00e3o offset UV usado em uma variedade de tintas nas maiores, geralmente de 15% a 21%, portanto, a dispers\u00e3o e a moagem s\u00e3o muito importantes, geralmente a primeira resina de dispers\u00e3o, o diluente ativo, o umectante e o dispersante e a dispers\u00e3o do pigmento no moinho de areia na dispers\u00e3o e na moagem, feitos de pasta de cor e, em seguida, misturam o restante dos componentes, com a moagem da m\u00e1quina de tr\u00eas rolos feita de tinta.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>How formulators usually evaluate this photoinitiator topic<\/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>Refer\u00eancias de produtos recomendadas<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/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\/pt\/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\/pt\/product\/irgacure-1173-cas-7473-98-5\/\">CHLUMINIT 1173<\/a>:<\/strong> A practical comparison point for classic short-wave UV initiation.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/product\/photoinitiator-itx-cas-5495-84-1\/\">CHLUMINIT ITX<\/a>:<\/strong> A useful long-wave support route in many printing-ink packages.<\/li>\n<\/ul>\n<h3>FAQ para compradores e formuladores<\/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.
