A maior vantagem das tintas \u00e0 base de \u00e1gua \u00e9 a \u00f3bvia redu\u00e7\u00e3o das emiss\u00f5es de COV (Compostos Org\u00e2nicos Vol\u00e1teis) na atmosfera, o que pode reduzir efetivamente os efeitos nocivos dos solventes prejudiciais aos seres humanos e a polui\u00e7\u00e3o dos produtos de embalagem, especialmente adequados para a impress\u00e3o de embalagens de alimentos, bebidas, produtos farmac\u00eauticos, cigarros e outros produtos com requisitos rigorosos de higiene. No entanto, devido \u00e0 natureza de seus componentes, as tintas \u00e0 base de \u00e1gua t\u00eam uma caracter\u00edstica distinta: s\u00e3o propensas \u00e0 forma\u00e7\u00e3o de espuma. A forma\u00e7\u00e3o de espuma afeta o bom andamento do processo de impress\u00e3o e a qualidade do produto impresso.<\/p>\n<p>&nbsp;<\/p>\n<p>A espuma pertence ao sistema de dispers\u00e3o de g\u00e1s disperso em l\u00edquido. A espuma \u00e9 a forma\u00e7\u00e3o de uma massa de g\u00e1s envolta por um filme l\u00edquido, e o processo de destrui\u00e7\u00e3o da espuma consiste em separar o g\u00e1s do filme l\u00edquido de grosso a fino, at\u00e9 a ruptura do processo. Os fatores que afetam a estabilidade da espuma dependem principalmente da velocidade de afinamento do filme l\u00edquido (ou seja, a taxa de perda de l\u00edquido na camada l\u00edquida) e da for\u00e7a do filme l\u00edquido.<\/p>\n<p>&nbsp;<\/p>\n<p>Na gera\u00e7\u00e3o de espuma, a \u00e1rea de superf\u00edcie do l\u00edquido aumenta, a energia do sistema aumenta; na destrui\u00e7\u00e3o da espuma, a \u00e1rea de superf\u00edcie do l\u00edquido diminui, a energia do sistema diminui, do ponto de vista energ\u00e9tico, a redu\u00e7\u00e3o da tens\u00e3o superficial do l\u00edquido favorece a forma\u00e7\u00e3o de espuma e a alta tens\u00e3o superficial do l\u00edquido n\u00e3o facilita a forma\u00e7\u00e3o de espuma. Entretanto, a baixa tens\u00e3o superficial n\u00e3o contribui necessariamente para a estabilidade da espuma. Somente quando o filme l\u00edquido tem uma certa resist\u00eancia, \u00e9 poss\u00edvel formar bolhas poli\u00e9dricas, a baixa tens\u00e3o superficial ajuda na estabilidade da espuma.<\/p>\n<p>&nbsp;<\/p>\n<p>A tinta \u00e0 base de \u00e1gua \u00e9 uma tinta l\u00edquida, muito mais fina do que a tinta offset, e no processo de transfer\u00eancia de impress\u00e3o de tinta \u00e9 f\u00e1cil misturar-se ao g\u00e1s e gerar espuma. O material de liga\u00e7\u00e3o da tinta \u00e0 base de \u00e1gua \u00e9 feito pela resina do tipo solu\u00e7\u00e3o ou emuls\u00e3o, \u00e1gua e uma pequena quantidade de etanol e aditivos. A resina precisa ser dissolvida em \u00e1gua por meio de rea\u00e7\u00e3o de am\u00f4nia. Essa resina sol\u00favel em \u00e1gua tem uma estrutura semelhante a sab\u00e3o e \u00e9 f\u00e1cil de produzir bolhas. Al\u00e9m disso, para melhorar a ades\u00e3o das tintas \u00e0 base de \u00e1gua ao substrato, \u00e9 necess\u00e1rio adicionar alguns surfactantes para reduzir a tens\u00e3o superficial do sistema, e a menor tens\u00e3o superficial promover\u00e1 a gera\u00e7\u00e3o de bolhas. Portanto, muitas vezes \u00e9 necess\u00e1rio adicionar antiespumantes ao imprimir com tintas \u00e0 base de \u00e1gua.<\/p>\n<p>&nbsp;<\/p>\n<p>A aplica\u00e7\u00e3o de antiespumantes est\u00e1 em conflito com as medidas para melhorar a estabilidade da espuma. Alguns antiespumantes s\u00e3o rea\u00e7\u00f5es qu\u00edmicas para atingir o objetivo de antiespumar (como sais de \u00e1cido ou c\u00e1lcio que podem destruir a pel\u00edcula de sab\u00e3o), enquanto a maioria dos antiespumantes reduz ainda mais a tens\u00e3o superficial do sistema, de modo que s\u00e3o f\u00e1ceis de espalhar e adsorver na superf\u00edcie do l\u00edquido, reduzindo assim a for\u00e7a da pel\u00edcula da superf\u00edcie do l\u00edquido para atingir o objetivo de antiespumar. Os tipos de antiespumantes s\u00e3o diversos, al\u00e9m de \u00e1lcoois, \u00e1cidos graxos, fosfatos, amidas, etc., o \u00f3leo de silicone tamb\u00e9m \u00e9 um excelente antiespumante comumente usado.<\/p>\n<p>&nbsp;<\/p>\n<p>Ele pode ser usado em sistemas aquosos e n\u00e3o aquosos. A tens\u00e3o superficial do \u00f3leo de silicone \u00e9 extremamente baixa e, quando adicionado a sistemas aquosos, ele ser\u00e1 preferencialmente adsorvido no filme l\u00edquido, de modo que o filme formado tenha uma tens\u00e3o superficial menor do que a superf\u00edcie original do filme formador de bolhas. Como regra geral, \u00e9 mais prov\u00e1vel que isso produza bolhas, mas como o antiespumante de \u00f3leo de silicone \u00e9 um hidrocarboneto de cadeia curta, embora tenha uma tens\u00e3o superficial mais baixa, pode fazer com que a for\u00e7a do filme de superf\u00edcie formado seja muito baixa e, portanto, pode promover a ruptura de bolhas, de modo a atingir efetivamente o objetivo de eliminar as bolhas.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><div class=\"vc_row-full-width vc_clearfix\"><\/div><section id=\"ut-section-69f9747ae857a\"

defect first and then screens compatibility, dosage range, and process stage. That is often much more reliable than choosing only by chemistry family or by a single dramatic lab result.<\/p>\n<ul>\n<li><strong>Start from the defect, not the additive name:<\/strong> wetting loss, crater, microfoam, and instability often need different solutions even inside the same formula.<\/li>\n<li><strong>Check compatibility at the intended dosage:<\/strong> the strongest additive can still be the wrong commercial choice if it narrows the process window too much.<\/li>\n<li><strong>Review the stage of use:<\/strong> some products are most useful during grind, while others matter more during let-down, filling, or final application.<\/li>\n<li><strong>Balance cure or film quality with defect control:<\/strong> the right additive fixes the problem without sacrificing adhesion, gloss, or appearance.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/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\/pt\/product\/chlumiaf-094\/\">CHLUMIAF 094<\/a>:<\/strong> A balanced defoamer reference for waterborne coatings and many general foam-control screens.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiaf-3062\/\">CHLUMIAF 3062<\/a>:<\/strong> Useful when printing-ink and UV-ink compatibility matter in the defoaming screen.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiaf-3037\/\">CHLUMIAF 3037<\/a>:<\/strong> A stronger process-defoaming option when persistent foam survives harsher conditions.<\/li>\n<\/ul>\n<h3>FAQ for buyers and formulators<\/h3>\n<p><strong>Why does an additive that looks powerful in a beaker sometimes fail in production?<\/strong><br \/>Because shear, temperature, substrate, and the full formula can all change the way the additive performs under real process conditions.<\/p>\n<p><strong>Should the most aggressive additive always be preferred?<\/strong><br \/>Not usually. The best additive is the one that solves the real defect while preserving the broadest safe operating window.<\/p>\n<p><!-- lc-commercial-end --><\/p>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] Water-based inks are prone to blistering, defoamer in water-based inks Water-based ink, can be diluted with water or ethanol, can be rinsed with tap water, but printed on the<\/p>","protected":false},"author":1,"featured_media":5913,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[114],"tags":[],"class_list":["post-5937","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-catalysts-chemical-auxiliary-agents"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.3.1 -
