Aplicativo:<\/strong>
\nO CHLUMIAO\u00aeDSTDP \u00e9 um tipo de antioxidante auxiliar de tio\u00e9ster com excelente desempenho. Seu efeito antioxidante \u00e9 maior do que o do CHLUMIAO\u00aeDLTDP, com baixa volatilidade, baixa perda de processamento t\u00e9rmico, sem polui\u00e7\u00e3o e sem colora\u00e7\u00e3o. Tem um efeito sin\u00e9rgico quando usado junto com os principais antioxidantes CHLUMIAO\u00ae 1010 e CHLUMIAO\u00ae 1076, CHLUMIAO\u00ae CA, etc. \u00c9 amplamente utilizado em produtos derivados do petr\u00f3leo, como polietileno, polipropileno e resina ABS, e a dosagem geral \u00e9 de 0,1% a 1,0%.<\/p>\n

Armazenamento:<\/strong><\/p>\n

Evite a exposi\u00e7\u00e3o ao sol ou o armazenamento em altas temperaturas e deve ser armazenado em local fresco, seco e ventilado para evitar umidade, \u00e1gua e calor.<\/p>\n

Pacote:<\/strong>
\nUse caixa de papel\u00e3o forrada com saco pl\u00e1stico, o peso l\u00edquido de cada caixa \u00e9 de 25 kg<\/p>\n<\/div>\n

<\/p>\n

Quando entramos em contato com pl\u00e1sticos ou outros pol\u00edmeros, frequentemente ouvimos falar de antioxidantes. Talvez tamb\u00e9m entendamos que a adi\u00e7\u00e3o de antioxidantes \u00e9 antioxidante, antienvelhecimento, mas talvez a grande maioria dos amigos ainda n\u00e3o entenda o mecanismo. Hoje, aprenderemos a conhecer as causas do envelhecimento dos materiais polim\u00e9ricos, o mecanismo e sua solu\u00e7\u00e3o.<\/p>\n

O que \u00e9 oxida\u00e7\u00e3o?
\nExplica\u00e7\u00e3o profissional: a oxida\u00e7\u00e3o (oxida\u00e7\u00e3o), definida de forma restrita como a rea\u00e7\u00e3o qu\u00edmica entre o oxig\u00eanio e outros elementos materiais, tamb\u00e9m \u00e9 um processo importante da unidade qu\u00edmica. Em termos gerais, a oxida\u00e7\u00e3o se refere ao processo no qual uma subst\u00e2ncia perde el\u00e9trons (o n\u00famero de oxida\u00e7\u00e3o aumenta).
\nExplica\u00e7\u00e3o comum: amarelamento, envelhecimento, endurecimento, fragilidade, amolecimento, embotamento, ferrugem e outros fen\u00f4menos causados pelo vento, sol e chuva, oxig\u00eanio no ar, eros\u00e3o hidrodin\u00e2mica e e\u00f3lica podem ser categorizados como oxida\u00e7\u00e3o.<\/p>\n

O melhor exemplo \u00e9 o fen\u00f4meno de uma ma\u00e7\u00e3 cortada, exposta ao ar por algum tempo, que gradualmente se torna amarela. De fato, n\u00e3o s\u00e3o apenas as ma\u00e7\u00e3s que oxidam, nossa pele tamb\u00e9m oxida, produtos pl\u00e1sticos e pol\u00edmeros oxidam e envelhecem! O envelhecimento \u00e9 um processo comum na natureza, o mais comum ao nosso redor \u00e9 a vida desde o nascimento, o crescimento, o processo de envelhecimento, que \u00e9 o mais t\u00edpico de um processo de envelhecimento.<\/p>\n

A corros\u00e3o de materiais met\u00e1licos tamb\u00e9m \u00e9 um tipo de envelhecimento, de objetos brilhantes para ferrugem, at\u00e9 a perda de valor.
\nO mesmo acontece com os pol\u00edmeros. Durante o processamento e o uso, devido aos efeitos combinados de calor, oxig\u00eanio, \u00e1gua, luz, microrganismos, meios qu\u00edmicos e outros fatores ambientais, a composi\u00e7\u00e3o qu\u00edmica e a estrutura dos pol\u00edmeros sofrem uma s\u00e9rie de altera\u00e7\u00f5es, e suas propriedades f\u00edsicas se deterioram, como endurecimento, ader\u00eancia, fragilidade, descolora\u00e7\u00e3o, perda de resist\u00eancia etc., o que \u00e9 conhecido como envelhecimento.<\/p>\n

Envelhecimento do pol\u00edmero molecular, o que produzir\u00e1 problemas?
\n1, reduzir as propriedades mec\u00e2nicas
\n2, descolora\u00e7\u00e3o
\n3, reduzir a transpar\u00eancia
\n4, amarelamento, envelhecimento
\n5, rachaduras
\n6, odor (\u00e1lcoois, alde\u00eddos, cetonas)
\n—–
\nEnvelhecimento de pol\u00edmeros, quais s\u00e3o os fatores respons\u00e1veis?
\n1, a estrutura do pol\u00edmero: liga\u00e7\u00e3o dupla, o anel de benzeno n\u00e3o \u00e9 uma estrutura suficientemente est\u00e1vel, o que leva facilmente \u00e0 decomposi\u00e7\u00e3o do pol\u00edmero e ao amarelamento
\n2, s\u00edntese de pol\u00edmero de impurezas residuais: per\u00f3xido, \u00edons met\u00e1licos levam \u00e0 degrada\u00e7\u00e3o do pol\u00edmero, amarelamento
\n3\u3001Oxig\u00eanio (ar): a presen\u00e7a de oxig\u00eanio, oz\u00f4nio causado pela decomposi\u00e7\u00e3o do pol\u00edmero
\n4, energia: estresse mec\u00e2nico, calor, luz ultravioleta
\n5\u3001Polui\u00e7\u00e3o do ar: NOx, SOx.
\n6, \u00e1gua, umidade: pode levar \u00e0 dissolu\u00e7\u00e3o, precipita\u00e7\u00e3o de biol\u00f3gicos: degrada\u00e7\u00e3o causada por enzimas biol\u00f3gicas<\/p>\n

Por que os pol\u00edmeros envelhecem?
\nOs pol\u00edmeros formam mol\u00e9culas de estado excitado na presen\u00e7a de calor ou luz. Quando a energia \u00e9 alta o suficiente, as cadeias moleculares se quebram para formar radicais livres, que podem formar rea\u00e7\u00f5es em cadeia dentro do pol\u00edmero que continuam a iniciar a degrada\u00e7\u00e3o e tamb\u00e9m podem causar liga\u00e7\u00f5es cruzadas. O culpado: Radicais livres R-<\/p>\n

Se houver oxig\u00eanio ou oz\u00f4nio no ambiente, uma s\u00e9rie de rea\u00e7\u00f5es de oxida\u00e7\u00e3o tamb\u00e9m \u00e9 induzida, resultando na forma\u00e7\u00e3o de hidroper\u00f3xidos (ROOH), que se decomp\u00f5em em grupos carbonila.
\nSe houver \u00edons met\u00e1licos residuais do catalisador no pol\u00edmero ou se \u00edons met\u00e1licos como cobre, ferro, mangan\u00eas, cobalto etc. forem introduzidos durante o processamento ou o uso, a rea\u00e7\u00e3o de degrada\u00e7\u00e3o oxidativa do pol\u00edmero ser\u00e1 acelerada. Os pol\u00edmeros protegem contra o envelhecimento.<\/p>\n

Portanto, os antioxidantes se tornaram um elixir que salva vidas para o setor de materiais!
\nPara evitar o envelhecimento dos pol\u00edmeros, voc\u00ea pode isolar a luz e o calor e, o mais importante, adicionar antioxidantes! Ent\u00e3o, aqui est\u00e1 a quest\u00e3o! Onde encontrar antioxidantes eficientes, genu\u00ednos e de boa qualidade?<\/p>","protected":false},"excerpt":{"rendered":"
