Придание шероховатости поверхности полимерных пленок

Изобретение относится к металлообработке и, более конкретно, к улучшению шероховатости поверхности ламинированных металлических изделий, таких как алюминиевые банки для напитков. Шероховатость поверхности полимерной пленки, которой ламинирована металлическая подложка, может быть улучшена за счет применения достаточного нагрева после нанесения слоя воска на полимерную пленку. В некоторых случаях тонкую жидкую пленку или слой дисперсии воска на водной основе могут наносить на поверхность металлической подложки, ламинированной полимерной пленкой. После нагревания полимерной пленки и слоя воска до температуры, при которой полимерная пленка и слой воска начинают расплавляться, шероховатость поверхности полимерной пленки может улучшиться благодаря наличию воска. Изобретение обеспечивает создание банки для напитков, обладающей достаточной защитой между металлом банки для напитка и содержащимся в нем напитком, чтобы избежать повреждения металла агрессивными напитками, такими как газированные напитки ...

СИСТЕМЫ И СПОСОБЫ БЕСКОНТАКТНОГО НАТЯЖЕНИЯ МЕТАЛЛИЧЕСКОЙ ПОЛОСЫ

Изобретение относится к области прокатки. Способы бесконтактного натяжения металлической полосы во время обработки металла включают пропускание металлической полосы рядом с магнитным ротором. Магнитный ротор расположен на первом расстоянии от металлической полосы, при этом создают натяжение металлической полосы посредством магнитного ротора путем вращения магнитного ротора. Вращение магнитного ротора приводит к возбуждению магнитного поля в металлической полосе, так что металлическая полоса испытывает натяжение в направлении вверх или вниз по технологической цепочке. В других аспектах вращение магнитного ротора возбуждает магнитное поле в металлической полосе, так что к металлической полосе прилагается усилие, нормальное к поверхности металлической полосы. Изобретение обеспечивает возможность регулирования усилия натяжения полосы при ее разматывании или сматывании в процессе прокатки без повреждения ее поверхности. 3 н. и 14 з.п. ф-лы, 8 ил.
