O processo de cura \u00e9 um processo de rea\u00e7\u00e3o fotoqu\u00edmica, ou seja, sob a a\u00e7\u00e3o da energia da luz ultravioleta, o pr\u00e9-pol\u00edmero \u00e9 curado em um filme em um per\u00edodo muito curto de tempo; a luz UV, al\u00e9m de causar a cura da superf\u00edcie do material, penetra mais na tinta l\u00edquida cur\u00e1vel por UV e estimula a cura adicional da tinta profunda; em compara\u00e7\u00e3o com a tinta tradicional, a polimeriza\u00e7\u00e3o da tinta cur\u00e1vel por UV e a secagem s\u00e3o mais completas, sem qualquer evapora\u00e7\u00e3o ou contaminantes \u00e0 base de solvente, cura 100%. A tecnologia de cura por UV foi desenvolvida rapidamente no mundo e nos setores de eletr\u00f4nicos, impress\u00e3o, constru\u00e7\u00e3o, decora\u00e7\u00e3o, medicina, maquin\u00e1rio, qu\u00edmica e automotivo para promover a aplica\u00e7\u00e3o.<\/p>\n<p>&nbsp;<\/p>\n<p>A tecnologia de cura por UV \u00e9 amplamente utilizada, principalmente por causa de suas vantagens exclusivas: cura r\u00e1pida, atendendo \u00e0s necessidades da produ\u00e7\u00e3o automatizada moderna; livre de polui\u00e7\u00e3o, em linha com a dire\u00e7\u00e3o do desenvolvimento de revestimentos e tintas modernos; filme de revestimento de alta qualidade, alta dureza, resist\u00eancia a arranh\u00f5es, resist\u00eancia \u00e0 corros\u00e3o e outras vantagens, e tem atra\u00eddo muita aten\u00e7\u00e3o.<\/p>\n<p>&nbsp;<\/p>\n<p>Aqui discutimos os seis fatores que afetam a cura incompleta por luz UV<\/p>\n<p>&nbsp;<\/p>\n<p>1, a energia da luz ultravioleta.<\/p>\n<p>(1). A energia da luz UV \u00e9 insuficiente, geralmente porque a densidade de pot\u00eancia de produ\u00e7\u00e3o da l\u00e2mpada UV \u00e9 muito pequena ou porque os par\u00e2metros do transformador n\u00e3o correspondem, o que causa uma cura incompleta.<\/p>\n<p>(2). Os revestimentos UV no fotoiniciador n\u00e3o s\u00e3o suficientes para absorver uma energia UV razo\u00e1vel, resultando em uma cura incompleta.<\/p>\n<p>&nbsp;<\/p>\n<p>2. A temperatura dentro do forno UV est\u00e1 muito baixa.<\/p>\n<p>Forno UV devido ao volume excessivo de ar do ventilador centr\u00edfugo ou ao papel do resfriamento excessivo da \u00e1gua, a situa\u00e7\u00e3o de bloqueio de oxig\u00eanio \u00e9 muito forte, resultando em temperatura da superf\u00edcie da l\u00e2mpada UV muito baixa para funcionar corretamente, resultando em cura incompleta dos revestimentos UV.<\/p>\n<p>&nbsp;<\/p>\n<p>3, a dist\u00e2ncia da l\u00e2mpada de cura por luz.<\/p>\n<p>A l\u00e2mpada UV e o refletor e a dist\u00e2ncia entre a superf\u00edcie do objeto iluminado \u00e9 de 7 a 8 cm quando a energia UV \u00e9 mais forte, mas, de acordo com os diferentes substratos de cura, a dist\u00e2ncia geral de cura \u00e9 selecionada em cerca de 10 a 15 cm.<\/p>\n<p>(1). A dist\u00e2ncia \u00e9 muito baixa, pois a temperatura da superf\u00edcie da l\u00e2mpada UV \u00e9 muito alta e o substrato \u00e9 deformado pelo calor.<\/p>\n<p>(2). A dist\u00e2ncia \u00e9 muito alta, a energia UV \u00e9 pequena, a superf\u00edcie do substrato n\u00e3o est\u00e1 seca e pegajosa.<\/p>\n<p>&nbsp;<\/p>\n<p>4, a espessura do revestimento UV.<\/p>\n<p>A espessura do revestimento UV desempenha um papel fundamental no efeito da cura UV, de acordo com a tonalidade da tinta, a temperatura, a velocidade de cura, a superf\u00edcie do substrato e outras condi\u00e7\u00f5es diferentes para a implanta\u00e7\u00e3o adequada.<\/p>\n<p>(1). O revestimento \u00e9 muito espesso, o tempo de secagem \u00e9 relativamente longo sob a irradia\u00e7\u00e3o da mesma fonte de luz de pot\u00eancia, o que, por um lado, afeta a secagem profunda do revestimento UV e, por outro lado, faz com que a temperatura da superf\u00edcie do substrato fique muito alta, levando \u00e0 deforma\u00e7\u00e3o do substrato.<\/p>\n<p>(2). A camada de revestimento \u00e9 muito fina, o que resultar\u00e1 em um brilho ruim na superf\u00edcie do produto e n\u00e3o conseguir\u00e1 obter o efeito de superf\u00edcie necess\u00e1rio.<\/p>\n<p>&nbsp;<\/p>\n<p>5. Velocidade da correia transportadora da linha de revestimento.<\/p>\n<p>De acordo com os diferentes substratos, revestimentos e dist\u00e2ncia de cura, a velocidade da correia transportadora do equipamento, ou seja, a velocidade da fotopolimeriza\u00e7\u00e3o, deve ser ajustada adequadamente.<\/p>\n<p>(1). A velocidade de cura \u00e9 muito r\u00e1pida, o revestimento UV da superf\u00edcie do substrato fica pegajoso ou a superf\u00edcie seca, mas n\u00e3o seca por dentro.<\/p>\n<p>(2). Se a velocidade de opera\u00e7\u00e3o for lenta, a superf\u00edcie do substrato envelhecer\u00e1.<\/p>\n<p>&nbsp;<\/p>\n<p>6, o ambiente do processo de fotopolimeriza\u00e7\u00e3o.<\/p>\n<p>A viscosidade do revestimento UV muda muito devido \u00e0 temperatura, portanto, a temperatura ambiente deve ser ajustada, geralmente controlada a 15-25 \u2103 \u00e9 mais apropriada; a temperatura muito baixa produzir\u00e1 o fen\u00f4meno da casca de laranja, e preste aten\u00e7\u00e3o para que a impress\u00e3o n\u00e3o seja exposta \u00e0 luz solar direta.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><a
