Una l\u00ednea de pel\u00edcula CPE mate sufr\u00eda acumulaci\u00f3n de material sobre un rodillo de contacto recubierto de silicona l\u00edquida. El rodillo funcionaba bien reci\u00e9n recubierto, pero despu\u00e9s de aproximadamente dos d\u00edas empezaba a formarse una fina capa de residuo semejante a una piel.<\/p>

Era dif\u00edcil de limpiar, aumentaba el tiempo de parada, generaba desperdicio durante limpieza y arranque y afectaba al aspecto mate. Bajo la luz, la superficie parec\u00eda tener una capa fina levantada o desprendida.<\/p>

Cuando se limpiaba esa capa, el efecto mate pod\u00eda recuperarse. Esto indicaba que el problema estaba estrechamente relacionado con el estado de la superficie despu\u00e9s del funcionamiento, no \u00fanicamente con la pel\u00edcula.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Contacto con pel\u00edcula caliente y sensibilidad del acabado mate<\/h2>\r\n

CPE matte film is sensitive to contact surface condition. In this type of film line, the roller is not only helping the material pass through the line. Its surface condition can also affect release, surface reflection, and the final matte appearance.<\/p>\r\n

The line used a die temperature of around 220\u00b0C, and the roller worked in a hot film contact section. After repeated contact, the previous LSR cover began to hold transferred material on the surface. Once this residue layer formed, the film was no longer contacting a stable silicone surface. The contact became less consistent, and the matte effect became harder to maintain.<\/p>\r\n

For this position, release behavior after running, heat stability, and easy cleaning were more important than simply matching the old roller as a normal replacement.<\/p>\r\n <\/div>\r\n <\/section>\r\n\r\n

El recubrimiento LSR anterior no mantuvo la superficie estable<\/h2>\r\n

The earlier roller was also made with liquid silicone rubber, but the cover specification did not stay stable enough under the actual running condition. It could work at the beginning, but after heat, contact pressure, and repeated film release, the surface started to collect residue.<\/p>\r\n

This kind of problem is common in demanding release positions. Two rollers may both be described as LSR rollers, but their actual behavior can be very different after production running. Compound design, curing condition, surface finish, hardness balance, and heat stability all affect whether the roller remains clean enough in service.<\/p>\r\n

In this case, the earlier cover did not provide enough release stability and heat resistance for the CPE matte film position. The result was frequent cleaning, unstable surface condition, and reduced control over the matte film appearance.<\/p>\r\n <\/div>\r\n <\/section>\r\n\r\n <\/div>\r\n<\/section>\r\n\r\n
