Se estiver abaixo dessa faixa, aumente a temperatura do aquecedor de condicionamento em 2 \u00b0C por ciclo e verifique novamente. Se a temperatura estiver correta, colete uma amostra de umidade pelo m\u00e9todo Karl Fischer diretamente da sa\u00edda da tremonha.

Primeiro, me\u00e7a a parede da pr\u00e9-forma a 0\u00b0, 90\u00b0, 180\u00b0 e 270\u00b0 usando um medidor ultrass\u00f4nico. Se a pr\u00f3pria pr\u00e9-forma estiver exc\u00eantrica (desvio maior que 0,05 mm), o problema est\u00e1 na ferramenta de inje\u00e7\u00e3o \u2014 tipicamente um desequil\u00edbrio de temperatura na zona do canal quente ou uma ponta de inje\u00e7\u00e3o obstru\u00edda. Se a pr\u00e9-forma for sim\u00e9trica, o problema \u00e9 mec\u00e2nico \u2014 tipicamente uma haste de estiramento desgastada ou exc\u00eantrica com TIR superior a 0,1 mm.

Calcule a sua taxa de alongamento axial (comprimento da pr\u00e9-forma em rela\u00e7\u00e3o ao comprimento da garrafa) e a taxa de alongamento circunferencial (di\u00e2metro externo da pr\u00e9-forma em rela\u00e7\u00e3o ao di\u00e2metro externo da garrafa). Se a taxa de alongamento biaxial combinada (BUR) for inferior a 10\u00d7, o projeto da pr\u00e9-forma \u00e9 fundamentalmente inadequado para o volume de garrafa desejado \u2014 isso requer um redesenho da pr\u00e9-forma, e n\u00e3o um ajuste no processo. Se a BUR estiver correta, verifique a temperatura da \u00e1gua de resfriamento do molde: garrafas desmoldadas acima de 15 \u00b0C apresentam uma orienta\u00e7\u00e3o molecular parcialmente relaxada, reduzindo diretamente a resist\u00eancia \u00e0 compress\u00e3o. Verifique tamb\u00e9m se a temperatura de condicionamento da pr\u00e9-forma n\u00e3o ultrapassa 115 \u00b0C, pois pr\u00e9-formas superaquecidas t\u00eam sua resist\u00eancia natural ao alongamento reduzida.<\/p>\n<\/div>\n<\/div>\n<div style=\"background: #fff; border-radius: 10px; border: 1px solid #e2e8f0; overflow: hidden;\">\n<div style=\"padding: 20px 24px; border-left: 4px solid #f97316;\">\n<h3 style=\"font-family: 'Barlow Condensed',sans-serif; font-size: 18px; font-weight: 800; color: #0a1628; margin: 0 0 10px;\">Qual o teor de umidade do PET necess\u00e1rio para a moldagem por sopro com estiramento?<\/h3>\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.8;\">A resina PET deve ser seca at\u00e9 um teor de umidade de 50 ppm ou inferior (medido por titula\u00e7\u00e3o de Karl Fischer) antes da inje\u00e7\u00e3o no processo ISBM. Acima de 50 ppm, as mol\u00e9culas de \u00e1gua hidrolisam as liga\u00e7\u00f5es \u00e9ster do PET em temperaturas do cilindro de 270\u2013295 \u00b0C, gerando g\u00e1s CO\u2082 que forma bolhas vis\u00edveis na parede da garrafa.
