Este produto \u00e9 conhecido pela sua excelente qualidade e tem um pre\u00e7o muito competitivo. Chimassorb 944 \u00e9 um estabilizador de luz de amina impedida polim\u00e9rica que oferece estabilidade t\u00e9rmica e de luz a longo prazo para v\u00e1rios pol\u00edmeros.<\/p>\n<p>Tem uma f\u00f3rmula molecular de (C35H69N5O)n, e o seu peso molecular m\u00e9dio \u00e9 de cerca de 2000 - 5000. O produto apresenta-se como um p\u00f3 branco a esbranqui\u00e7ado. Tem um intervalo de ponto de fus\u00e3o de aproximadamente 100 - 135\u00b0C. O Chimassorb 944 \u00e9 sol\u00favel em solventes org\u00e2nicos comuns, como tolueno, xileno e ciclohexanona, mas tem baixa solubilidade em \u00e1gua.<\/p>\n<h2 id=\"uses\">Utiliza\u00e7\u00f5es do produto<\/h2>\n<p>O chimassorb 944 de alta qualidade \u00e9 amplamente utilizado na ind\u00fastria de pol\u00edmeros. Pode ser adicionado a poliolefinas (como o polietileno e o polipropileno), pol\u00edmeros estir\u00e9nicos (como o poliestireno e o ABS) e pl\u00e1sticos de engenharia (como a poliamida e o poli\u00e9ster). <\/p>\n<p>No caso das poliolefinas, ajuda a evitar a degrada\u00e7\u00e3o das cadeias polim\u00e9ricas causada pela luz ultravioleta (UV) e pelo calor. Isto leva a uma melhor reten\u00e7\u00e3o da cor, redu\u00e7\u00e3o de fissuras e aumento da vida \u00fatil dos produtos pl\u00e1sticos finais. Por exemplo, em mobili\u00e1rio de pl\u00e1stico para exterior, a adi\u00e7\u00e3o de chimassorb 944 pode garantir que o mobili\u00e1rio mant\u00e9m o seu aspeto original e as suas propriedades mec\u00e2nicas durante mais tempo.<\/p>\n<p>Em revestimentos, pode ser utilizado para aumentar a durabilidade da pel\u00edcula de revestimento. Protege o revestimento contra o amarelecimento, a perda de brilho e a fissura\u00e7\u00e3o devido \u00e0 exposi\u00e7\u00e3o prolongada \u00e0 luz solar e a outros factores ambientais. Isto \u00e9 particularmente importante para revestimentos de autom\u00f3veis, revestimentos arquitect\u00f3nicos e revestimentos industriais.<\/p>\n<h2 id=\"usage\">Como utilizar o produto<\/h2>\n<p>Ao utilizar o chimassorb 944 de alta qualidade, \u00e9 crucial seguir a dosagem recomendada. O intervalo de dosagem t\u00edpico \u00e9 de 0,1 - 1,5% por peso, dependendo do tipo de pol\u00edmero, da aplica\u00e7\u00e3o final e do n\u00edvel de prote\u00e7\u00e3o esperado. <\/p>\n<p>Para o processamento de pol\u00edmeros, pode ser adicionado durante os processos de extrus\u00e3o, moldagem por inje\u00e7\u00e3o ou moldagem por sopro. Pode ser pr\u00e9 - misturado com os gr\u00e2nulos de pol\u00edmero ou adicionado diretamente ao equipamento de processamento. \u00c9 importante assegurar a dispers\u00e3o uniforme do estabilizador na matriz polim\u00e9rica para obter os melhores resultados. <\/p>\n<p>Nos revestimentos, pode ser adicionado durante a fase de formula\u00e7\u00e3o. Deve ser cuidadosamente misturado com outros componentes do revestimento para garantir uma distribui\u00e7\u00e3o homog\u00e9nea no sistema de revestimento.<\/p>\n<h2 id=\"case_studies\">Estudos de casos de utiliza\u00e7\u00e3o<\/h2>\n<p>Caso 1: Uma empresa de fabrico de pl\u00e1sticos produzia caixotes do lixo exteriores em polietileno. Antes de utilizar o chimassorb 944, os caixotes come\u00e7avam a apresentar sinais de desbotamento da cor, fissuras e perda de resist\u00eancia mec\u00e2nica ap\u00f3s cerca de 6 meses de exposi\u00e7\u00e3o ao ar livre. Ap\u00f3s a incorpora\u00e7\u00e3o de 0,8% em peso de chimassorb 944 na resina de polietileno durante o processo de extrus\u00e3o, as caixas mantiveram a sua cor original e as suas propriedades mec\u00e2nicas durante mais de 2 anos. Este facto n\u00e3o s\u00f3 melhorou a qualidade do produto, como tamb\u00e9m aumentou a satisfa\u00e7\u00e3o do cliente e reduziu os custos de p\u00f3s-venda da empresa.<\/p>\n<p>Caso 2: Um fabricante de revestimentos para autom\u00f3veis estava a enfrentar problemas com a durabilidade da sua camada superior. O revestimento come\u00e7ava a amarelar e a perder o brilho ap\u00f3s alguns meses de exposi\u00e7\u00e3o \u00e0 luz solar. Ao adicionar 0,5% em peso de chimassorb 944 \u00e0 formula\u00e7\u00e3o do revestimento, o amarelecimento foi significativamente reduzido e a reten\u00e7\u00e3o do brilho foi melhorada. Isto levou a um aumento da competitividade no mercado dos seus revestimentos para autom\u00f3veis.<\/p>\n<h2 id=\"contact\">Informa\u00e7\u00f5es de contacto<\/h2>\n<p>Se voc\u00ea tiver alguma d\u00favida sobre Alta qualidade chimassorb 944 cas 71878 - 19 - 8, n\u00e3o hesite em contactar-nos.
