produto<\/h2>\n<p>Um rolo para pel\u00edculas estiradas biaxialmente foi concebido para as etapas de processamento a alta velocidade e sens\u00edveis \u00e0 temperatura utilizadas na produ\u00e7\u00e3o de pel\u00edculas pl\u00e1sticas orientadas. A JWELL fornece solu\u00e7\u00f5es de rolos para linhas de estiramento biaxial BOPP, BOPET, BOPA e BOPI, bem como tipos de rolos utilizados em equipamentos para separadores de baterias de l\u00edtio. As posi\u00e7\u00f5es de processo dispon\u00edveis incluem rolos de arrefecimento, estiramento, pr\u00e9-aquecimento, tra\u00e7\u00e3o, corona, borracha e revestidos a TEFLON.<\/p>\n<p>Como os rolos de produ\u00e7\u00e3o de pel\u00edculas funcionam a velocidades de rota\u00e7\u00e3o elevadas, a precis\u00e3o da equilibragem din\u00e2mica \u00e9 essencial para um desempenho est\u00e1vel da linha. A JWELL utiliza equipamento dedicado de inspe\u00e7\u00e3o de equilibragem din\u00e2mica de grande escala e v\u00e1rios m\u00e9todos de equilibragem para verificar rolos destinados a aplica\u00e7\u00f5es exigentes de pel\u00edcula. Isto contribui para uma rota\u00e7\u00e3o suave e um funcionamento fi\u00e1vel quando s\u00e3o necess\u00e1rias estabilidade da banda e condi\u00e7\u00f5es de processamento consistentes.<\/p>\n<p>A varia\u00e7\u00e3o da temperatura da superf\u00edcie dos rolos \u00e9 outro fator importante na conforma\u00e7\u00e3o de pel\u00edculas pl\u00e1sticas. Os rolos podem utilizar um canal interno de circula\u00e7\u00e3o em espiral para melhorar a permuta t\u00e9rmica ao longo da superf\u00edcie de trabalho. A conce\u00e7\u00e3o destina-se a minimizar a flutua\u00e7\u00e3o de temperatura admiss\u00edvel durante a produ\u00e7\u00e3o, contribuindo para condi\u00e7\u00f5es t\u00e9rmicas mais uniformes nas etapas de estiramento da pel\u00edcula e processamento relacionado.<\/p>\n<p>Para a produ\u00e7\u00e3o de separadores de baterias de l\u00edtio, a gama de produtos pode incluir rolos de estiramento, secagem e extra\u00e7\u00e3o concebidos para cumprir os requisitos de precis\u00e3o e estabilidade do equipamento. Os compradores devem indicar o tipo de pel\u00edcula, a posi\u00e7\u00e3o do rolo, o comprimento da face e o di\u00e2metro, a velocidade da linha, o meio de controlo da temperatura, o tratamento de superf\u00edcie, o requisito de equilibragem e as condi\u00e7\u00f5es de funcionamento. Estes dados permitem avaliar a estrutura do rolo e a configura\u00e7\u00e3o do processo para a linha pretendida de pel\u00edculas BOPP, BOPET, BOPA, BOPI ou de separadores.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rolos de alta precis\u00e3o para linhas de estiramento BOPP, BOPET, BOPA e BOPI, com equilibragem din\u00e2mica a alta velocidade, permuta t\u00e9rmica eficiente por canais em espiral e baixa varia\u00e7\u00e3o da temperatura superficial.
