Os compradores geralmente comparam um pacote com v\u00e1rios fotoiniciadores em vez de um produto isolado.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>A tecnologia de cura por UV \u00e9 amplamente dividida em sistemas radicais livres de UV e sistemas cati\u00f4nicos de UV. Os revestimentos cati\u00f4nicos de UV com excelentes propriedades de processamento em latas de metal, a\u00e7o laminado e ind\u00fastria de embalagens flex\u00edveis s\u00e3o amplamente utilizados, e o principal mercado agora tamb\u00e9m est\u00e1 na Europa e nos Estados Unidos.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Os materiais UV cati\u00f4nicos e UV de radicais livres s\u00e3o muito diferentes, mas a composi\u00e7\u00e3o geral \u00e9 semelhante. Os sistemas cati\u00f4nicos s\u00e3o dominados por materiais ep\u00f3xi, mas o ep\u00f3xi comum do tipo bisfenol A reage lentamente, com mais aplica\u00e7\u00f5es de materiais alic\u00edclicos do tipo ep\u00f3xi\/oxetano; os sistemas de radicais livres est\u00e3o agora muito maduros comercialmente, com materiais de acrilato modificados com ep\u00f3xi\/poli\u00e9ster\/poliuretano que oferecem mais op\u00e7\u00f5es de solu\u00e7\u00f5es.<\/p>\n<p>&nbsp;<\/p>\n<p>O sistema cati\u00f4nico UV pode escolher menos tipos de mat\u00e9rias-primas em compara\u00e7\u00e3o com o sistema de radical livre, e o pol\u00edmero \u00e9 principalmente a resina ep\u00f3xi alic\u00edclica de baixa viscosidade. Tomemos como exemplo as resinas ep\u00f3xi alic\u00edclicas.<\/p>\n<p>O TTA21 de v\u00e1rias especifica\u00e7\u00f5es de pureza \u00e9 o produto mais dominante no setor de revestimentos UV. Como a aplica\u00e7\u00e3o de revestimentos UV cati\u00f4nicos continua a crescer significativamente, espera-se que a quantidade de resinas ep\u00f3xi alic\u00edclicas representadas pelo TTA21 aumente.<\/p>\n<p>&nbsp;<\/p>\n<p>Na aplica\u00e7\u00e3o espec\u00edfica de tintas\/revestimentos, al\u00e9m de ambos necessitarem de luz UV para fornecer energia de cura, os dois sistemas apresentam grandes diferen\u00e7as nas caracter\u00edsticas de desempenho e rea\u00e7\u00e3o.<\/p>\n<p>&nbsp;<\/p>\n<p>1. Efeito de bloqueio de oxig\u00eanio<\/p>\n<p>O sistema cati\u00f4nico UV n\u00e3o tem o efeito de bloquear o oxig\u00eanio, mas tem mais medo da \u00e1gua; a umidade afetar\u00e1 a efici\u00eancia de cura do sistema cati\u00f4nico; os radicais livres UV s\u00e3o o oposto e s\u00e3o mais afetados pelo bloqueio de oxig\u00eanio.<\/p>\n<p>&nbsp;<\/p>\n<p>2. Ades\u00e3o ao substrato<\/p>\n<p>Normalmente, nos casos em que \u00e9 mais dif\u00edcil aderir \u00e0 superf\u00edcie do substrato, como vidro\/metal\/pl\u00e1stico de alta densidade, o c\u00e1tion UV tem melhor desempenho de ades\u00e3o do que a base livre de UV.<\/p>\n<p>&nbsp;<\/p>\n<p>3. Taxa de encolhimento do volume<\/p>\n<p>A taxa de encolhimento da cura da formula\u00e7\u00e3o do sistema de radicais livres UV \u00e9 geralmente superior a 10%, enquanto o sistema de c\u00e1tions UV pode controlar a taxa de encolhimento de 1-3%, sendo uma boa solu\u00e7\u00e3o para resolver o encolhimento do volume.<\/p>\n<p>&nbsp;<\/p>\n<p>4. Caracter\u00edsticas de cura escura<\/p>\n<p>O sistema de c\u00e1tion UV pode continuar a reagir \u00e0 camada interna depois de interromper a irradia\u00e7\u00e3o da fonte de luz, para completar o material ap\u00f3s a cura. Essas s\u00e3o as caracter\u00edsticas de cura escura, muito adequadas para aplica\u00e7\u00f5es de revestimento espesso, o aquecimento do c\u00e1tion ap\u00f3s a velocidade de cura \u00e9 significativamente \u00fatil; o radical livre UV \u00e9 um sistema de rea\u00e7\u00e3o stop-and-go.<\/p>\n<p>&nbsp;<\/p>\n<p>5. Seguran\u00e7a de contato<\/p>\n<p>O grau de rea\u00e7\u00e3o do sistema de c\u00e1tion UV \u00e9 pr\u00f3ximo a 100%, a seguran\u00e7a pode ser certificada por testes REACH\/FDA, pode ser usada em embalagens de alimentos e outros campos relacionados.<\/p>\n<p>&nbsp;<\/p>\n<p>6. Velocidade de cura da luz<\/p>\n<p>Em geral, a velocidade de cura do sistema radical livre UV \u00e9 maior do que a do sistema cati\u00f4nico, afetada pela secagem da superf\u00edcie cati\u00f4nica dos produtos bloqueadores de oxig\u00eanio, mas a velocidade real de secagem n\u00e3o \u00e9 t\u00e3o r\u00e1pida quanto a do radical livre.<\/p>\n<p>&nbsp;<\/p>\n<p>Notas de formula\u00e7\u00e3o<\/p>\n<p>&nbsp;<\/p>\n<p>O sistema de c\u00e1tion UV pode ser misturado com o sistema de radical livre UV em qualquer propor\u00e7\u00e3o, chamado de sistema h\u00edbrido UV, pode melhorar a velocidade de cura relativa do c\u00e1tion UV e do encolhimento do radical livre UV, afetado pela barreira de oxig\u00eanio e outras defici\u00eancias, a mesma espessura de filme da diferen\u00e7a de energia de cura do sistema n\u00e3o \u00e9 grande.<\/p>\n<p>&nbsp;<\/p>\n<p>O sistema de c\u00e1tion UV depende do iniciador gerado pelo \u00e1cido forte de Lewis para fazer o ponto ativo da rea\u00e7\u00e3o de abertura do anel; a f\u00f3rmula geralmente afeta a atividade do iniciador do material, principalmente pigmentos org\u00e2nicos azo (podem ser modificados para fazer a prote\u00e7\u00e3o) e radicais livres misturados com TPO\/819\/907 e outras estruturas que cont\u00eam P, S e outros elementos do iniciador, e semelhante a 115 aminas de v\u00e1rios n\u00edveis.<\/p>\n<p>&nbsp;<\/p>\n<p>A umidade tem um impacto maior sobre a cura do sistema de c\u00e1tion UV, portanto, \u00e9 adequado controlar a umidade ambiente dentro de 50%, enquanto o aquecimento acelera a taxa de rea\u00e7\u00e3o.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><a href=\"https:\/\/longchangchemical.com\/pt\/product\/uv-photoinitiator\/\"><span style=\"color:
