O ponto de fulgor do alto e do baixo afeta diretamente a aplica\u00e7\u00e3o de plastificantes, o que significa o ponto de fulgor do plastificante? Como testar o ponto de fulgor do plastificante?<\/p>\n<p>Primeiro, qual \u00e9 o significado de ponto de fulgor do plastificante?<\/p>\n<p>1, o ponto de fulgor do plastificante<\/p>\n<p>O ponto de fulgor, tamb\u00e9m conhecido como ponto de fulgor, \u00e9 um dos indicadores importantes de l\u00edquidos inflam\u00e1veis; os plastificantes, como material molecular l\u00edquido, tamb\u00e9m t\u00eam um ponto de fulgor. A temperatura do ponto de fulgor do plastificante \u00e9 mais baixa do que o ponto de igni\u00e7\u00e3o, \u00e9 um plastificante l\u00edquido na superf\u00edcie da mistura de vapores e ar em contato com o fogo e a primeira ocorr\u00eancia de temperatura de fulgor de chama azul. O ponto de fulgor do plastificante com o mesmo ponto de igni\u00e7\u00e3o, indicando o tamanho da possibilidade de explos\u00e3o ou inc\u00eandio, o transporte, o armazenamento e o uso da seguran\u00e7a t\u00eam uma grande rela\u00e7\u00e3o.<\/p>\n<p>2, o impacto do ponto de fulgor do plastificante<\/p>\n<p>O ponto de fulgor e a volatilidade do plastificante, a temperatura de processamento e outros aspectos relacionados, na sele\u00e7\u00e3o do plastificante, o ponto de fulgor pode ser usado como refer\u00eancia para alguns outros indicadores.<br \/>\n(1) A rela\u00e7\u00e3o entre o ponto de fulgor e a volatilidade: o mesmo que o ponto de ebuli\u00e7\u00e3o do plastificante, quanto menor o ponto de fulgor, indicando que maior a volatilidade do plastificante.<br \/>\n(2) A rela\u00e7\u00e3o entre o ponto de fulgor e a temperatura de processamento: quanto mais baixo for o ponto de fulgor, isso indica que as condi\u00e7\u00f5es de combust\u00edvel do plastificante s\u00e3o mais relaxadas; portanto, ao processar, \u00e9 necess\u00e1rio prestar aten\u00e7\u00e3o especial ao fato de que a temperatura de processamento \u00e9 maior do que o ponto de fulgor do plastificante, caso contr\u00e1rio, a possibilidade de perigo aumenta.<br \/>\nPlastificante ambiental de PVC para uso geral<br \/>\nSegundo, o m\u00e9todo de detec\u00e7\u00e3o do ponto de fulgor do plastificante<\/p>\n<p>O m\u00e9todo de detec\u00e7\u00e3o do ponto de fulgor do plastificante consiste em encher a amostra de plastificante no copo de teste at\u00e9 a linha de superf\u00edcie l\u00edquida especificada, o in\u00edcio de um aumento mais r\u00e1pido na temperatura da amostra e, em seguida, lentamente a uma taxa constante para se aproximar do ponto de fulgor e, de tempos em tempos, na temperatura especificada para testar a pequena chama varrida sobre a superf\u00edcie do l\u00edquido no copo sobre a superf\u00edcie do l\u00edquido devido \u00e0 chama e \u00e0 causa da superf\u00edcie l\u00edquida dos vapores no flash de fogo quando o limite de temperatura, ou seja, para o ponto de fulgor dos plastificantes. As etapas espec\u00edficas s\u00e3o as seguintes:<br \/>\n1, antes que o teste seja aberto para o ventilador de exaust\u00e3o.<br \/>\n2, a amostra ser\u00e1 carregada no copo de medi\u00e7\u00e3o, de modo que a superf\u00edcie do l\u00edquido plastificante e a parede do n\u00edvel da linha gravada do copo, uma pipeta muito grande seja sugada, como manchas fora do copo, precisem ser despejadas, lavadas e secas depois de recarregar a amostra, conforme necess\u00e1rio.<br \/>\n3\u3001Coloque o copo de medi\u00e7\u00e3o de teste na mesa de aquecimento do instrumento.<br \/>\n4\u3001Insira o sensor fixo e o term\u00f4metro no copo de medi\u00e7\u00e3o de modo que fique a 6 ml do fundo do copo.<br \/>\n5 \u3001 Aque\u00e7a o copo de medi\u00e7\u00e3o, quando a temperatura atingir o ponto de fulgor esperado, acenda o dispositivo de igni\u00e7\u00e3o e ajuste o di\u00e2metro da chama para cerca de 4 ml.<br \/>\n6, quando pr\u00f3ximo ao ponto de fulgor do plastificante, aumento da temperatura em velocidade constante, de modo que a superf\u00edcie da amostra do vapor dispare, quando a amostra na superf\u00edcie l\u00edquida do in\u00edcio da extin\u00e7\u00e3o instant\u00e2nea da chama azul, registre a temperatura, como um ponto de fulgor da amostra de plastificante.<br \/>\n7. No final do teste, feche o dispositivo de igni\u00e7\u00e3o a tempo, o sensor e o term\u00f4metro levantados, o copo de teste removido da plataforma de aquecimento do instrumento e, em seguida, desligue o interruptor de alimenta\u00e7\u00e3o da fonte de g\u00e1s.<br \/>\n8, para ser resfriado na amostra do copo, despeje-o no balde de reciclagem de l\u00edquidos residuais e limpe e seque o copo de medi\u00e7\u00e3o em tempo h\u00e1bil para testar novamente.<br \/>\nPlastificantes ambientais P-fenil<br \/>\nTerceiro, o ponto de fulgor das notas de teste do plastificante<\/p>\n<p>1, o teste deve ser selecionado para evitar o vento e o local claro, o operador n\u00e3o deve sair no meio.<br \/>\n2, ao final do teste, fa\u00e7a um bom trabalho de limpeza e corte a fonte de alimenta\u00e7\u00e3o e a fonte de g\u00e1s.<br \/>\n3, para garantir a precis\u00e3o dos dados do teste, os copos de medi\u00e7\u00e3o abertos devem ser limpos e secos em tempo h\u00e1bil.<br \/>\n4, o teste deve ter medidas de seguran\u00e7a para evitar queimaduras, inc\u00eandios e outros acidentes.<\/p>\n<p>Qual \u00e9 o significado do ponto de fulgor do plastificante, acima est\u00e1 a defini\u00e7\u00e3o do ponto de fulgor e os m\u00e9todos de detec\u00e7\u00e3o para voc\u00ea organizar, espero ajud\u00e1-lo. N\u00e3o \u00e9 dif\u00edcil perceber que o ponto de fulgor do plastificante afeta diretamente a temperatura do ambiente do plastificante, portanto, na sele\u00e7\u00e3o, \u00e9 preciso prestar mais aten\u00e7\u00e3o ao ponto de fulgor para evitar perigos devido \u00e0 alta temperatura do processamento do produto.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Plastificantes retardantes de chama da mesma s\u00e9rie<\/strong><\/h2>\n<table style=\"border-collapse: collapse;
