Tiene un ancho de rodillo de 300 mm y permite un ajuste flexible del espesor de la chapa dentro del rango de 0,2 a 2 mm. Los rodillos de acero est\u00e1n cromados duramente y pulidos a espejo, y cuentan con una dureza Rockwell superior a 60 para garantizar su durabilidad durante un uso a largo plazo. Las opciones de calentamiento incluyen calentamiento el\u00e9ctrico o por aceite para adaptarse a los requisitos espec\u00edficos del proceso; el sistema admite temperaturas de hasta 300 \u00b0C con una precisi\u00f3n de control de \u00b12 \u00b0C, lo que cumple plenamente con las exigencias de estabilidad t\u00e9rmica de la formulaci\u00f3n de compuestos de PVC.<\/p>\n\n\n\n
En laminador abierto de dos rodillos<\/strong> Est\u00e1 dise\u00f1ada para ofrecer una alta seguridad operativa, y cuenta con un mecanismo de apagado autom\u00e1tico que se activa mediante la cubierta protectora y un sistema de frenado de emergencia que se activa al abrirse la puerta en sentido contrario. El espacio entre los dos rodillos se puede ajustar manualmente con una precisi\u00f3n de 0,01 mm, lo que permite un control preciso del espesor de la l\u00e1mina. Est\u00e1 equipada con una pantalla t\u00e1ctil TFT de Siemens y un sistema de control centralizado PLC de Siemens; una funci\u00f3n de almacenamiento de recetas facilita el cambio r\u00e1pido entre los par\u00e1metros del proceso, mientras que las protecciones de seguridad mec\u00e1nicas y el\u00e9ctricas garantizan el cumplimiento de las normas de seguridad de la CE.<\/p>\n\n\n\n El PVC es un material sensible al calor con un rango de procesamiento muy limitado; las temperaturas insuficientes provocan una plastificaci\u00f3n inadecuada, mientras que las temperaturas excesivas causan descomposici\u00f3n y decoloraci\u00f3n. La HTR-120 utiliza un sistema de control de temperatura de precisi\u00f3n para mantener la temperatura de la superficie del rodillo dentro del rango establecido, lo que previene de manera efectiva la degradaci\u00f3n t\u00e9rmica del PVC durante el proceso de compuestos. In PVC formulation development, the uniformity of the mixing process directly impacts product performance. Issues such as poor plasticizer dispersion or uneven heat stabilizer distribution become immediately apparent during a trial run on an open two-roll mill. Hartek recently conducted a pre-sales trial for a client using a laboratory-scale two-roll open mill (Model: HTR-120).
