Durante o armazenamento de longo prazo da resina de goma-laca, devido \u00e0 polimeriza\u00e7\u00e3o de v\u00e1rios genes livres, a vida t\u00e9rmica do produto de resina \u00e9 reduzida, o ponto de fus\u00e3o aumenta, a cor se aprofunda e a mat\u00e9ria insol\u00favel em etanol quente aumenta gradualmente, esse \u00e9 o \"envelhecimento\" da resina de goma-laca. Durante esse processo, a resina de goma-laca se aglomera em peda\u00e7os duros que s\u00e3o dif\u00edceis de esmagar, chamados de \"aglomera\u00e7\u00e3o\". A qualidade dos produtos de resina envelhecida e aglomerada diminuir\u00e1 at\u00e9 certo ponto.<\/h4>\n\n<!-- lc-qa-start -->\n<p><strong>Quick answer:<\/strong> For general industrial-chemical topics, the safest commercial decision usually comes from checking application fit, specification, process compatibility, and handling requirements together instead of relying on one simplified rule.<\/p>\n<!-- lc-qa-end -->\n\n\n\n\n\n\n<h4 class=\"wp-block-heading\">O envelhecimento e a aglomera\u00e7\u00e3o dos produtos de goma-laca est\u00e3o relacionados \u00e0s condi\u00e7\u00f5es de armazenamento. Quando a temperatura, o aumento da umidade ou os catalisadores est\u00e3o presentes, eles aceleram o envelhecimento e a aglomera\u00e7\u00e3o.<\/h4>\n\n\n\n<h4 class=\"wp-block-heading\">Tendo em vista as caracter\u00edsticas qu\u00edmicas e f\u00edsicas da pel\u00edcula de insetos, ela deve ser armazenada em local seco, ventilado e fresco, evitando o sol, a chuva e a proximidade do calor e da umidade. Nesse ambiente de armazenamento, a goma-laca pode ser armazenada por tr\u00eas anos, e os produtos com mais de tr\u00eas anos devem ser inspecionados novamente para confirmar que atendem aos padr\u00f5es antes de serem usados.<\/h4>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Entre em contato conosco agora!<\/strong><\/h4>\n\n\n\n<h4 class=\"wp-block-heading\">Aceitamos servi\u00e7os personalizados e, normalmente, entraremos em contato com voc\u00ea dentro de 24 horas.
