Por exemplo, a altera\u00e7\u00e3o da superf\u00edcie do carbonato de c\u00e1lcio afeta os comp\u00f3sitos de borracha. Isso afeta seu desempenho. Al\u00e9m disso, o carbonato de c\u00e1lcio pesado e o N550 fortalecem a borracha de cloropreno quando adicionados. A borracha usava malha 800, malha 2.800 e carbonato de c\u00e1lcio pesado de malha 4.000. Foi comparado com carbonato de c\u00e1lcio leve. Os resultados mostraram que:<\/p>\n\n\n\n<p>A borracha preenchida com carbonato de c\u00e1lcio pesado apresenta maior tens\u00e3o de tra\u00e7\u00e3o e menor viscosidade Mooney. Isso \u00e9 comparado \u00e0 borracha preenchida com carbonato de c\u00e1lcio leve. Isso melhora o processamento. Al\u00e9m disso, o tempo de queima \u00e9 um pouco mais curto. Mas ainda atende aos requisitos de produ\u00e7\u00e3o.<\/p>\n\n\n\n<p>\u00c0 medida que o tamanho da malha do carbonato de c\u00e1lcio pesado aumenta, a viscosidade Mooney aumentar\u00e1. O mesmo acontecer\u00e1 com o tempo de queima e a resist\u00eancia \u00e0 tra\u00e7\u00e3o. O mesmo acontecer\u00e1 com a resist\u00eancia ao rasgo e \u00e0 ruptura do composto de borracha. Este aumento melhorar\u00e1 a seguran\u00e7a do processamento e as propriedades mec\u00e2nicas. No entanto, o coeficiente de envelhecimento pode ser ligeiramente menor. Isso reduziria a resist\u00eancia ao envelhecimento.<\/p>\n\n\n\n<p>A borracha preenchida com carbonato de c\u00e1lcio pesado \u00e9 mais lisa. Tamb\u00e9m \u00e9 mais resistente ao envelhecimento e ao ar. Eles s\u00e3o melhores do que aqueles de borracha leve com enchimento de carbonato de c\u00e1lcio. Eles s\u00e3o como compostos de borracha preenchidos com carbonato de c\u00e1lcio leve. Eles t\u00eam as mesmas propriedades mec\u00e2nicas e de flex\u00e3o e perda de histerese. Mas, adicionar carbonato de c\u00e1lcio pesado a camadas de borracha herm\u00e9ticas ainda pode melhor\u00e1-las bastante. Essas vantagens do carbonato de c\u00e1lcio pesado o tornam amplamente utilizado. \u00c9 usado em compostos de borracha de camada herm\u00e9tica. Compostos de borracha herm\u00e9ticos s\u00e3o usados principalmente em edif\u00edcios e na ind\u00fastria aeroespacial. Eles impedem vazamentos de g\u00e1s, vapor de \u00e1gua ou l\u00edquido. Sua qualidade afeta diretamente o desempenho de seguran\u00e7a do projeto. Portanto, o carbonato de c\u00e1lcio pesado \u00e9 uma carga inorg\u00e2nica de alta qualidade. Pode melhorar o desempenho da borracha herm\u00e9tica. Tamb\u00e9m reduz custos e ajuda ind\u00fastrias relacionadas.<\/p>","protected":false},"excerpt":{"rendered":"<p>Agora, a borracha herm\u00e9tica do pneu usa principalmente carbonato de c\u00e1lcio leve para aumentar o volume.
