O material branco geralmente tem uma leve absor\u00e7\u00e3o de luz azul de 450 a 480 nm na luz vis\u00edvel, o que causa uma falta de azul, tornando-o levemente amarelado e dando uma sensa\u00e7\u00e3o de envelhecimento. Por esse motivo, as pessoas tomaram diferentes medidas para tornar os itens mais brancos e coloridos. Antes do surgimento do agente de clareamento fluorescente, havia dois m\u00e9todos principais de clareamento normalmente usados.<\/p>\n<p>1, adicionar o m\u00e9todo de clareamento azul. Esse m\u00e9todo pode ter um efeito de clareamento, mas o efeito \u00e9 limitado e, como a quantidade total de luz refletida \u00e9 reduzida, os itens escurecem.<\/p>\n<p>2, m\u00e9todo de branqueamento qu\u00edmico. Principalmente por meio da rea\u00e7\u00e3o redox e do desbotamento do material, mas a celulose causar\u00e1 alguns danos, e o tecido alvejado geralmente fica amarelo, mas afeta o efeito de clareamento.<\/p>\n<p>&nbsp;<\/p>\n<p>O agente de clareamento fluorescente pode compensar as defici\u00eancias do m\u00e9todo de clareamento tradicional e apresenta grande superioridade. O agente clareador fluorescente pode absorver a luz ultravioleta pr\u00f3xima de energia mais alta, de modo que suas mol\u00e9culas entrem no estado excitado e, em seguida, as mol\u00e9culas excitadas saltem para o estado fundamental de energia mais baixa e emitam fluoresc\u00eancia. O comprimento de onda fluorescente da radia\u00e7\u00e3o \u00e9 de cerca de 450 nm de luz azul, a cor amarela dos itens amarelados pode ser compensada pela luz azul refletida pelo agente clareador fluorescente, aumentando assim a brancura aparente dos itens. Como a intensidade da luz emitida excede a intensidade da luz vis\u00edvel original projetada no tecido tratado, \u00e9 produzido um efeito de clareamento levemente crom\u00e1tico.<\/p>\n<p>O uso do agente de branqueamento fluorescente \u00e9 muito amplo, desde o uso inicial apenas para t\u00eaxteis, at\u00e9 agora amplamente utilizado em papel, detergentes, pl\u00e1sticos, revestimentos, tintas, couro e muitos outros campos, o uso do agente de branqueamento fluorescente e a quantidade ainda est\u00e1 em expans\u00e3o. O agente de branqueamento fluorescente com valor pr\u00e1tico, al\u00e9m de absorver a luz ultravioleta e emitir fluoresc\u00eancia azul-violeta e alta efici\u00eancia de fluoresc\u00eancia, deve ser quase incolor ou ligeiramente amarelo, com as caracter\u00edsticas dos corantes comuns, boa afinidade com tecidos branqueados, como fibras, boas propriedades de solubilidade ou dispers\u00e3o e melhor solidez \u00e0s propriedades de lavagem, luz solar e engomar. Em pa\u00edses de todo o mundo, a propor\u00e7\u00e3o de branqueadores fluorescentes usados em diferentes setores \u00e9 diferente, mas o uso da propor\u00e7\u00e3o da ordem \u00e9 basicamente o mesmo: ou seja, usado principalmente em detergentes, seguido por papel, terceiros t\u00eaxteis, pl\u00e1sticos e outras \u00e1reas de menor quantidade. Os branqueadores fluorescentes tamb\u00e9m podem ser usados em combina\u00e7\u00e3o com absorvedores de UV para resolver o problema de branqueamento por intemp\u00e9ries de alguns produtos de pol\u00edmero.<\/p>\n<p>A rea\u00e7\u00e3o de fluoresc\u00eancia refere-se \u00e0 subst\u00e2ncia que aceita a irradia\u00e7\u00e3o da luz UV invis\u00edvel e \u00e9 radicalizada e, em seguida, a energia da radicaliza\u00e7\u00e3o no processo de libera\u00e7\u00e3o da luz vis\u00edvel, que \u00e9 uma fotoluminesc\u00eancia do fen\u00f4meno de luminesc\u00eancia fria. Os fluorescentes podem produzir rea\u00e7\u00f5es fluorescentes, mas os elementos que produzem rea\u00e7\u00f5es fluorescentes n\u00e3o s\u00e3o apenas agentes fluorescentes. A luz fluorescente mostrar\u00e1 a rea\u00e7\u00e3o fluorescente da subst\u00e2ncia, mas nem todo agente clareador fluorescente \u00e9 fluorescente. Alguns produtos qu\u00edmicos di\u00e1rios de alta qualidade com ingredientes naturais, como vitamina E e glicerina, tamb\u00e9m ser\u00e3o expostos \u00e0 luz violeta de 365 nm para mostrar uma rea\u00e7\u00e3o fluorescente. Portanto, a irradia\u00e7\u00e3o com luz violeta s\u00f3 pode comprovar a presen\u00e7a de rea\u00e7\u00e3o fluorescente, mas n\u00e3o pode identificar se \u00e9 um agente clareador fluorescente.<\/p>\n<p>Internacionalmente, o agente clareador fluorescente \u00e9 considerado um corante branco, e cada estrutura do agente clareador fluorescente tem seu n\u00famero de \u00edndice de corante correspondente. Na China, os branqueadores fluorescentes s\u00e3o geralmente considerados um importante auxiliar de acabamento funcional. De acordo com o tipo de estrutura qu\u00edmica, os branqueadores fluorescentes usados no setor t\u00eaxtil incluem principalmente seis categorias: 1, tipo bis(triazinilamino)estilbeno; 2, tipo estilbeno bifenil; 3, tipo bis(benzo)azole; 4, tipo estilbeno; 5, tipo pirazolina; 6, tipo cumarina. Ao usar o agente de clareamento fluorescente, o agente de clareamento fluorescente apropriado deve ser selecionado de acordo com a composi\u00e7\u00e3o qu\u00edmica e as propriedades f\u00edsicas da fibra, de modo a obter um efeito de clareamento satisfat\u00f3rio.<\/p>\n<p>Como mencionado acima, o primeiro grande uso de branqueadores fluorescentes \u00e9 na lavagem de roupas. O detergente para tecidos \u00e9 uma necessidade na vida cotidiana dos moradores. Os surfactantes e aditivos s\u00e3o os principais componentes dos detergentes para tecidos, que desempenham um papel fundamental no desempenho dos detergentes e no efeito de limpeza das roupas lavadas. As f\u00e1bricas de impress\u00e3o e tingimento t\u00eaxtil no tratamento de branqueamento fluorescente do tecido da f\u00e1brica s\u00e3o uma tecnologia comum e difundida, mas n\u00e3o alcan\u00e7am uma solidez permanente na lavagem, ou seja, \u00e0 medida que as pessoas usam e lavam, o agente de branqueamento fluorescente cai, a roupa fica velha e at\u00e9 amarelada etc. Adicionar uma certa quantidade de agente branqueador fluorescente no detergente com a variedade certa pode n\u00e3o apenas aumentar a brancura ou o brilho do tecido que est\u00e1 sendo lavado e melhorar o efeito de lavagem, mas tamb\u00e9m melhorar a apar\u00eancia do detergente. Atualmente, 50% do consumo mundial de branqueadores fluorescentes \u00e9 usado no setor de detergentes. Portanto, pode-se dizer que os branqueadores fluorescentes se tornaram um dos aditivos importantes e indispens\u00e1veis na formula\u00e7\u00e3o de detergentes para tecidos. Ao lavar roupas, um detergente geralmente enfrenta v\u00e1rias fibras de tecidos ao mesmo tempo, como algod\u00e3o, poli\u00e9ster-algod\u00e3o, poli\u00e9ster puro, l\u00e3, seda, viscose, n\u00e1ilon etc. Para obter um melhor efeito de clareamento e brilho em diferentes fibras ao mesmo tempo, h\u00e1 requisitos para a sele\u00e7\u00e3o de agentes clareadores fluorescentes. A classe de bifenil bis-estiril, a classe de aminostilbeno bis-triazina de branqueadores fluorescentes s\u00e3o dois amplamente utilizados na estrutura t\u00eaxtil do produto, o efeito de clareamento da fibra t\u00eaxtil \u00e9 bom e, mais importante, \u00e9 aplic\u00e1vel a uma ampla gama de variedades de fibras.<\/p>\n<p>Ap\u00f3s anos de experimentos cient\u00edficos e aplica\u00e7\u00f5es pr\u00e1ticas, o agente clareador fluorescente \u00e9 um produto qu\u00edmico seguro e inofensivo, al\u00e9m de ser dif\u00edcil de ser absorvido pelo corpo humano atrav\u00e9s da pele e causar riscos t\u00f3xicos. Essas subst\u00e2ncias s\u00e3o geralmente aceitas internacionalmente como aditivos convencionais para papel, produtos pl\u00e1sticos, t\u00eaxteis, detergentes para roupas etc.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Produtos da mesma s\u00e9rie<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<table style=\"border-collapse: collapse;
