Ela \u00e9 feita de uma mistura cuidadosa de aglutinantes, pigmentos (inclusive pigmentos, corantes etc.), cargas, aditivos e outras subst\u00e2ncias.<\/p>\n<p>H\u00e1 muitos tipos diferentes de tinta, que podem ser subdivididos de acordo com o m\u00e9todo de impress\u00e3o em tintas offset (litogr\u00e1ficas), tintas de rotogravura, tintas de impress\u00e3o tipogr\u00e1fica, tintas flexogr\u00e1ficas, tintas de serigrafia, tintas de tampografia e tintas de jato de tinta. Do ponto de vista do substrato, elas podem ser divididas em tintas para papel, tintas para pl\u00e1stico, tintas para metal, tintas para vidro, tintas para cer\u00e2mica e tintas para impress\u00e3o t\u00eaxtil. Em termos de m\u00e9todos de secagem, h\u00e1 tintas de secagem vol\u00e1til, tintas de secagem osm\u00f3tica, tintas de secagem oxidativa, tintas de cura por calor, tintas de cura por luz e tintas de cura por feixe de el\u00e9trons. Al\u00e9m disso, h\u00e1 tintas para fins especiais e de combate \u00e0 falsifica\u00e7\u00e3o, como tintas fotossens\u00edveis, tintas t\u00e9rmicas, tintas sens\u00edveis \u00e0 press\u00e3o, tintas espumantes, tintas perfumadas, tintas condutoras, tintas magn\u00e9ticas, tintas de cristal l\u00edquido, tintas para jato de tinta e tintas para microc\u00e1psulas, cada uma com suas pr\u00f3prias vantagens.<\/p>\n<p>Os m\u00e9todos representativos de secagem de tinta usados no processo de impress\u00e3o variam de acordo com o tipo de impress\u00e3o e incluem principalmente secagem por evapora\u00e7\u00e3o, secagem por osmose, secagem por polimeriza\u00e7\u00e3o oxidativa, cura por calor e cura por UV\/EB.<\/p>\n<p>A secagem por evapora\u00e7\u00e3o, por exemplo, funciona por meio de aquecimento para evaporar o solvente ou a umidade na tinta para obter a secagem. As tintas \u00e0 base de solvente cont\u00eam VOCs e t\u00eam um impacto negativo no meio ambiente. Por exemplo, os solventes \u00e0 base de \u00e1gua ou as tintas com solvente de alto ponto de ebuli\u00e7\u00e3o geralmente exigem grandes fornos para secar, o que inevitavelmente consome muita energia. Ap\u00f3s a secagem, o filme de tinta \u00e9 simplesmente os ingredientes s\u00f3lidos da tinta presos ao substrato, e sua resist\u00eancia depende muito da resist\u00eancia do pr\u00f3prio material conectado. Olhando para tr\u00e1s na hist\u00f3ria, nos prim\u00f3rdios do setor de impress\u00e3o, antes do despertar da consci\u00eancia ambiental, as tintas \u00e0 base de solvente eram amplamente utilizadas devido \u00e0s suas vantagens, como a velocidade de secagem r\u00e1pida. Entretanto, com o aumento das exig\u00eancias de prote\u00e7\u00e3o ambiental, suas desvantagens se tornaram gradualmente mais proeminentes.<\/p>\n<p>A secagem osm\u00f3tica envolve a permea\u00e7\u00e3o do solvente e da \u00e1gua da tinta no material do substrato, enquanto os componentes s\u00f3lidos, como a resina e o pigmento, aderem \u00e0 superf\u00edcie do substrato para concluir o processo de secagem. Esse tipo de tinta \u00e9 amplamente usado na impress\u00e3o em materiais absorventes porosos, como papel, por exemplo, impress\u00e3o de jornais, e tem as vantagens de tempos de secagem curtos e de n\u00e3o precisar de equipamentos especiais de secagem. No entanto, ela \u00e9 in\u00fatil para materiais n\u00e3o perme\u00e1veis, como pl\u00e1sticos. No caso pr\u00e1tico da impress\u00e3o colorida de jornais, \u00e9 necess\u00e1rio garantir que a tinta seque rapidamente e que a cor n\u00e3o seja distorcida ap\u00f3s a impress\u00e3o no papel, o que exige muito das propriedades de secagem penetrante da tinta.<\/p>\n<p>As tintas de secagem por polimeriza\u00e7\u00e3o oxidativa usam \u00f3leo de linha\u00e7a, \u00f3leo de soja e outros \u00f3leos que cont\u00eam liga\u00e7\u00f5es duplas como aglutinantes e dependem da rea\u00e7\u00e3o de polimeriza\u00e7\u00e3o oxidativa do oxig\u00eanio no ar para obter a secagem. Semelhante \u00e0 secagem osm\u00f3tica, embora n\u00e3o exija equipamentos especiais de secagem e n\u00e3o consuma energia, o processo de secagem leva um certo tempo e n\u00e3o pode prosseguir imediatamente para o pr\u00f3ximo processo. Na impress\u00e3o tradicional de livros, esse tipo de tinta j\u00e1 foi usado em grandes quantidades, mas a opera\u00e7\u00e3o de pulveriza\u00e7\u00e3o de p\u00f3 realizada para evitar que a sujeira aderisse ao verso pode causar problemas ambientais, o que levou o setor a buscar alternativas mais ecol\u00f3gicas.<\/p>\n<p>As tintas termofixas usam resinas de liga\u00e7\u00e3o cruzada termofixas, como resinas ep\u00f3xi, resinas de poliuretano e resinas amino como aglutinantes, e s\u00e3o combinadas com um agente de cura por calor para formar um sistema de dois componentes. Eles s\u00e3o misturados em uma propor\u00e7\u00e3o espec\u00edfica e agitados antes de serem aquecidos em um t\u00fanel de secagem por infravermelho ou com ar quente para reticular termicamente e curar o filme. Embora essas tintas tenham excelentes propriedades, seu alto consumo de energia, a evapora\u00e7\u00e3o do solvente e a falta de respeito ao meio ambiente levaram \u00e0 sua substitui\u00e7\u00e3o gradual por tintas UV que economizam energia e s\u00e3o ecologicamente corretas. Assim como algumas grandes gr\u00e1ficas, na busca por uma produ\u00e7\u00e3o eficiente e pela prote\u00e7\u00e3o ambiental, elas eliminaram suas linhas de produ\u00e7\u00e3o de tintas de cura t\u00e9rmica e passaram a usar tintas UV.<\/p>\n<p>As tintas de cura UV\/EB cont\u00eam subst\u00e2ncias reativas que s\u00e3o curadas por luz ultravioleta ou irradia\u00e7\u00e3o de feixe de el\u00e9trons. As tintas UV\/EB t\u00eam um impacto ambiental m\u00ednimo, pois n\u00e3o cont\u00eam solventes ou outros COVs e podem ser usadas em substratos n\u00e3o absorventes, como o pl\u00e1stico. As tintas UV\/EB podem ser curadas instantaneamente, de modo que a pr\u00f3xima etapa do processo pode come\u00e7ar imediatamente ap\u00f3s a impress\u00e3o. Elas tamb\u00e9m n\u00e3o curam sem exposi\u00e7\u00e3o \u00e0 luz ultravioleta (UV) ou de feixe de el\u00e9trons (EB) e, portanto, n\u00e3o aderem \u00e0 m\u00e1quina de impress\u00e3o. No campo da impress\u00e3o de embalagens de alimentos, por exemplo, as propriedades de cura r\u00e1pida das tintas UV podem efetivamente impedir que a tinta contamine os alimentos, garantindo a seguran\u00e7a dos mesmos.<\/p>\n<p>As tintas UV oferecem muitas vantagens: em primeiro lugar, n\u00e3o emitem solventes, o que \u00e9 seguro e n\u00e3o agride o meio ambiente; em segundo lugar, s\u00e3o altamente produtivas, com velocidades de impress\u00e3o de 100 a 400 m\/min e at\u00e9 mesmo de 1.500 a 3.000 m\/min para tintas de fibra \u00f3ptica, desempenhando um papel importante nas modernas linhas de produ\u00e7\u00e3o de impress\u00e3o de alta velocidade; em terceiro lugar, curam rapidamente, permitindo que os materiais impressos sequem rapidamente e sejam empilhados sem se contaminarem devido \u00e0 tinta n\u00e3o secar, eliminando a necessidade de tirar o p\u00f3 e mantendo o ambiente da impressora e da oficina limpo e livre de polui\u00e7\u00e3o por poeira. Em quarto lugar, a tinta cura imediatamente ap\u00f3s a impress\u00e3o, de modo que os pontos n\u00e3o se expandem e a tinta n\u00e3o penetra no papel, garantindo excelente qualidade de impress\u00e3o. A satura\u00e7\u00e3o, a intensidade e a clareza das cores do material impresso s\u00e3o significativamente melhores do que as das tintas comuns. Quinto, ela pode ser processada on-line, adaptando-se perfeitamente ao modelo de produ\u00e7\u00e3o de linha de montagem. Em sexto lugar, ela \u00e9 adequada para impress\u00e3o em substratos sens\u00edveis ao calor, ampliando a gama de materiais de impress\u00e3o.<\/p>\n<p>Entretanto, as tintas UV n\u00e3o s\u00e3o perfeitas. Seu pre\u00e7o relativamente alto limita seu escopo de aplica\u00e7\u00e3o at\u00e9 certo ponto. Em pequenas empresas de impress\u00e3o, onde o controle de custos \u00e9 rigorosamente aplicado, o fator pre\u00e7o muitas vezes as impede de usar tintas UV. Algumas mat\u00e9rias-primas (diluentes reativos, fotoiniciadores) t\u00eam odor, s\u00e3o t\u00f3xicas ou irritantes para a pele, o que tem um impacto negativo na aplica\u00e7\u00e3o da impress\u00e3o de embalagens para alimentos, medicamentos e produtos infantis. Na impress\u00e3o de embalagens de medicamentos, se a seguran\u00e7a das mat\u00e9rias-primas da tinta n\u00e3o puder ser garantida, isso pode representar uma amea\u00e7a potencial \u00e0 qualidade do medicamento. Al\u00e9m disso, as caracter\u00edsticas de cura instant\u00e2nea das tintas UV podem causar encolhimento do volume, o que aumenta a tens\u00e3o interna na camada de tinta e reduz a ades\u00e3o ao substrato. Isso \u00e9 mais \u00f3bvio em aplica\u00e7\u00f5es de impress\u00e3o para produtos como metal e pode afetar a durabilidade do material impresso. Al\u00e9m disso, ela precisa ser armazenada ao abrigo da luz e em baixas temperaturas (&lt;30\u00b0C) durante o transporte e o armazenamento, o que imp\u00f5e requisitos relativamente rigorosos \u00e0s condi\u00e7\u00f5es de armazenamento.<\/p>\n<p>O material de liga\u00e7\u00e3o das tintas UV s\u00e3o os olig\u00f4meros, principalmente resinas acr\u00edlicas com propriedades de cura pela luz. Em vez de solventes ou \u00f3leos, s\u00e3o usados diluentes reativos, principalmente poli\u00e9steres acr\u00edlicos com propriedades de cura pela luz. O catalisador \u00e9 um fotoiniciador, que pode sofrer uma rea\u00e7\u00e3o fotoqu\u00edmica sob luz ultravioleta para produzir radicais livres ou c\u00e1tions, que, por sua vez, iniciam a polimeriza\u00e7\u00e3o e a liga\u00e7\u00e3o cruzada dos olig\u00f4meros acr\u00edlicos e dos poli\u00e9steres acr\u00edlicos e, por fim, secam a tinta.<br \/>\nSe, no futuro, for poss\u00edvel desenvolver um novo tipo de material de tinta UV que mantenha suas vantagens de cura r\u00e1pida e respeito ao meio ambiente e, ao mesmo tempo, resolva problemas como pre\u00e7o alto e mat\u00e9rias-primas irritantes, o setor de impress\u00e3o certamente dar\u00e1 in\u00edcio a uma nova revolu\u00e7\u00e3o. Esse tipo de tinta poder\u00e1 ser amplamente utilizado em mais campos, promovendo ainda mais o desenvolvimento da tecnologia de impress\u00e3o, que se tornar\u00e1 mais eficiente, ecologicamente correta e de alta qualidade.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>A practical buying checklist for UV ink applications<\/h2>\n<p>In UV printing, the best technical choice usually comes from balancing curing performance with print behavior.
