Se o tamanho da part\u00edcula de negro de fumo for muito pequeno (20 nm), a concentra\u00e7\u00e3o de negro de fumo \u00e9 geralmente definida em 2,5%+0,5%. De acordo com o m\u00e9todo de fabrica\u00e7\u00e3o e utiliza\u00e7\u00e3o do negro de fumo, o pigmento negro de fumo geralmente \u00e9 melhor utilizado para colora\u00e7\u00e3o de pl\u00e1sticos, e sua sele\u00e7\u00e3o \u00e9 determinada basicamente pela escurid\u00e3o que o produto deve atingir.<\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Carrier_selection\"><\/span>Sele\u00e7\u00e3o de operadora<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">Para o transportador de masterbatch de negro de fumo, geralmente \u00e9 selecionado polietileno linear LLDPE com ampla aplicabilidade, principalmente na forma de p\u00f3. A resina LLDPE como transportador \u00e9 prop\u00edcia \u00e0 dispers\u00e3o e processamento de negro de fumo. Tamb\u00e9m \u00e9 adequado para moldagem por inje\u00e7\u00e3o por extrus\u00e3o e sopro de filme. Ap\u00f3s o enxerto, tamb\u00e9m \u00e9 usado para HIPS ABS PP LDPE HDPE, etc. O masterbatch de negro de fumo geralmente seleciona a resina com o mesmo \u00edndice de fus\u00e3o da resina de matriz pl\u00e1stica como transportador, e \u00e9 melhor selecionar a resina do mesmo sistema que o transportador.<\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Compatibility\"><\/span>Compatibilidade<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">Compatibilidade \u00e9 o fator que determina a qualidade do masterbatch de cor preta. Se o lote mestre de cores for produzido a partir de chips ou materiais reciclados, ele poder\u00e1 conter poluentes ou outros pol\u00edmeros n\u00e3o fus\u00edveis. Isso causar\u00e1 alguns problemas imprevis\u00edveis e dif\u00edceis, al\u00e9m de desperdi\u00e7ar tempo e mat\u00e9ria-prima do consumidor final. Neste momento, a resina base pode ser selecionada para produzir masterbatch de cores de alta qualidade, que apresenta boa compatibilidade durante o processo de fus\u00e3o. Masterbatch de cores de alta qualidade pode ser produzido com LLDPE, LDPE, HDPE, PP, PS, SAN, PA e outros materiais.<\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Requirements_of_dispersion_degree_on_equipment\"><\/span>Requisitos de grau de dispers\u00e3o em equipamentos<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">O masterbatch de cor preta \u00e9 produzido com negro de fumo. O negro de fumo bruto \u00e9 uma mistura muito dif\u00edcil e suja, cheia de poeira, leve e fofa. A menos que sejam adotadas medidas de tratamento em grande escala, isso poluir\u00e1 a m\u00e1quina e os trabalhadores e sujar\u00e1 o ambiente de trabalho. Por causa disso, geralmente \u00e9 selecionado para completar a pr\u00e9-dispers\u00e3o do negro de fumo em um transportador de resina, ou seja, o lote mestre de cor preta. O suporte de resina \u00e9 limpo, flui livremente e \u00e9 f\u00e1cil de usar. Al\u00e9m da sujeira, o negro de fumo tem outra caracter\u00edstica que \u00e9 dif\u00edcil de dispersar. Se o negro de fumo bruto for derretido diretamente durante a inje\u00e7\u00e3o no molde, o efeito de colora\u00e7\u00e3o ser\u00e1 muito fraco. As listras e manchas pretas de carbono sem dispers\u00e3o aparecer\u00e3o obviamente se estiverem pr\u00f3ximas dos locais com menos cor.<\/p>\n\n<p class=\"wp-block-paragraph\">O negro de fumo, que \u00e9 dif\u00edcil de dispersar, tamb\u00e9m confunde os fabricantes de masterbatch de cores. A dispers\u00e3o do masterbatch de cor preta \u00e9 muito fraca. Quando o usu\u00e1rio final mistura ou molda esses masterbatches pretos, seu desempenho \u00e9 apenas ligeiramente melhor do que o negro de fumo, mas o efeito tamb\u00e9m \u00e9 insatisfat\u00f3rio. Para obter uma dispers\u00e3o est\u00e1vel e elevada, \u00e9 necess\u00e1rio utilizar equipamento especial de alto n\u00edvel: misturador interno mais unidade de anel de \u00e1gua de parafuso duplo. Com for\u00e7a de dispers\u00e3o suficiente, o misturador interno mais a unidade de parafuso duplo podem misturar completamente o negro de fumo e a resina base para realizar a produ\u00e7\u00e3o cont\u00ednua.<\/p>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"764\" class=\"wp-image-5375\" src=\"https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1-1024x764.jpg\" alt=\"Masterbatch de negro de fumo 1\" srcset=\"https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1-1024x764.jpg 1024w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1-300x224.jpg 300w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1-600x448.jpg 600w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1-768x573.jpg 768w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-1.jpg 1190w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"830\" height=\"665\" class=\"wp-image-5374\" src=\"https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-2.jpg\" alt=\"Masterbatch de negro de fumo 2\" srcset=\"https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-2.jpg 830w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-2-300x240.jpg 300w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-2-600x481.jpg 600w, https:\/\/www.cowinextrusion.com\/wp-content\/uploads\/2023\/02\/Carbon-black-masterbatch-2-768x615.jpg 768w\" sizes=\"(max-width: 830px) 100vw, 830px\" \/><\/figure>\n<\/div>\n<\/div>\n\n<p class=\"wp-block-paragraph\">\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">\u00a0<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Selection of carbon black Carbon black is the most cheap, high-quality and excellent ultraviolet stabilizer.
