O fotoiniciador na inicia\u00e7\u00e3o da pr\u00e9-polimeriza\u00e7\u00e3o e na rea\u00e7\u00e3o de polimeriza\u00e7\u00e3o do mon\u00f4mero torna-se parte da estrutura do pol\u00edmero curado em um filme, e h\u00e1 uma parte n\u00e3o envolvida na cura em um filme.<\/p>\n<p>O efeito da concentra\u00e7\u00e3o do fotoiniciador sobre a taxa de cura por luz \u00e9 mostrado na figura. A partir da figura, pode-se observar que a concentra\u00e7\u00e3o do fotoiniciador em 7% da intensidade de luz UV necess\u00e1ria para a menor taxa de cura \u00e9 a mais r\u00e1pida, mas, em seguida, aumentar a concentra\u00e7\u00e3o em vez de reduzir a taxa de cura.<\/p>\n<p>Se a concentra\u00e7\u00e3o do fotoiniciador for muito alta, haver\u00e1 dois problemas: o primeiro \u00e9 que a fot\u00f3lise do fotoiniciador produzir\u00e1 parte do material n\u00e3o curado, enfraquecendo a resist\u00eancia qu\u00edmica e as propriedades f\u00edsicas do revestimento; O segundo \u00e9 a alta concentra\u00e7\u00e3o de fotoiniciador, a taxa de polimeriza\u00e7\u00e3o da superf\u00edcie e a taxa de polimeriza\u00e7\u00e3o da propor\u00e7\u00e3o do corpo do revestimento aumentam, diferentes espessuras do revestimento em diferentes tens\u00f5es, o que far\u00e1 com que o revestimento fique amassado, mas tamb\u00e9m levar\u00e1 a fraturas na estrutura de cura e na camada de cura e no substrato.<\/p>\n<p>O efeito inibit\u00f3rio do oxig\u00eanio na mol\u00e9cula de oxig\u00eanio do fotoiniciador \u00e9 um radical duplo de estado trilinear, embora n\u00e3o possa iniciar a polimeriza\u00e7\u00e3o do acrilato, mas \u00e9 f\u00e1cil competir com a rea\u00e7\u00e3o que envolve outros radicais. A fot\u00f3lise do fotoiniciador ap\u00f3s a forma\u00e7\u00e3o do estado trilinear e dos complexos de rea\u00e7\u00e3o do oxig\u00eanio, a decomposi\u00e7\u00e3o complexa da inativa\u00e7\u00e3o do iniciador do estado b\u00e1sico, esse fen\u00f4meno tamb\u00e9m \u00e9 conhecido como \"quenching\"; outro fen\u00f4meno \u00e9 que os radicais livres gerados pelo fotoiniciador e as mol\u00e9culas de oxig\u00eanio geram um per\u00f3xido mais est\u00e1vel, de modo que os radicais livres s\u00e3o \"removidos\". Esses dois fen\u00f4menos far\u00e3o com que a taxa de polimeriza\u00e7\u00e3o seja bastante reduzida; evid\u00eancias experimentais na presen\u00e7a de revestimento de oxig\u00eanio com espessura de 1pm dentro da taxa de cura ser\u00e3o reduzidas em 20 vezes.<\/p>\n<p>Para superar o impacto do oxig\u00eanio na taxa de cura, podem ser tomadas as seguintes medidas. Primeiro, o uso de g\u00e1s inerte, como a prote\u00e7\u00e3o de nitrog\u00eanio, esse m\u00e9todo de equipamento e os custos de material s\u00e3o mais altos; segundo, aumentar a concentra\u00e7\u00e3o de fotoiniciador; terceiro, o revestimento \u00e9 adequadamente misturado com cera, a cera flutuar\u00e1 na superf\u00edcie para formar uma camada protetora, isolar o papel do oxig\u00eanio, n\u00e3o deve ser muito quando misturado, caso contr\u00e1rio, afetar\u00e1 o brilho; Em quarto lugar, adicione um sensibilizador de amina para reduzir a inibi\u00e7\u00e3o do oxig\u00eanio na superf\u00edcie; em quinto lugar, adicione alguns grupos trifuncionais ou quatro grupos funcionais de mon\u00f4mero de acrilato.<\/p>\n<p>A escolha de fotoiniciadores a partir dos seguintes aspectos: um \u00e9 o pre\u00e7o, o pre\u00e7o de diferentes fotoiniciadores varia dezenas de vezes; o segundo \u00e9 a cor, alguns fotoiniciadores produzem subst\u00e2ncias coloridas ap\u00f3s a fot\u00f3lise, como o benzalde\u00eddo; o terceiro \u00e9 o cheiro, como o acoplamento de benzeno com dimetilcetona, a rea\u00e7\u00e3o produz formiato de metila, o odor n\u00e3o pode ser usado para embalagens de alimentos; O quarto \u00e9 a corrosividade, como os derivados da acetofenona, ap\u00f3s a rea\u00e7\u00e3o que produz \u00e1cido clor\u00eddrico; o quinto \u00e9 a estabilidade, duas benzofenonas e derivados de boa estabilidade, e a estabilidade da benzoildimetilcetona \u00e9 ruim; o sexto \u00e9 a taxa de cura, como a taxa de cura da benzofenona barata \u00e9 muito baixa; o s\u00e9timo \u00e9 que o fotoiniciador absorve os comprimentos de onda da luz UV, o gr\u00e1fico a seguir mostra v\u00e1rias faixas de comprimento de onda sens\u00edveis \u00e0 luz do fotoiniciador.<\/p>\n<p>&nbsp;<\/p>\n<h2><\/h2>\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\/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<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/product\/photoinitiator-cq\/\">CHLUMINIT CQ<\/a>:<\/strong> A direct reference for visible-light and color-sensitive curing discussions.<\/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.
