Respuesta breve:<\/strong>Al fabricar marcos de sellado rectangulares o de formas irregulares con tiras de silicona extruida, las uniones en las esquinas deben garantizar la continuidad de la secci\u00f3n transversal, la precisi\u00f3n dimensional y la estanqueidad tras la compresi\u00f3n. El m\u00e9todo de uni\u00f3n, el \u00e1ngulo de corte, las plantillas de posicionamiento y la vulcanizaci\u00f3n secundaria influyen conjuntamente en la resistencia y el aspecto.<\/p><\/blockquote>\n\n

\u00bfPara qu\u00e9 situaciones son adecuadas estas piezas de silicona?<\/h3>\n\n

Definir primero los escenarios de aplicaci\u00f3n reales ayuda a traducir los requisitos relativos a los materiales, la estructura y la verificaci\u00f3n en condiciones t\u00e9cnicas aplicables.<\/p>\n\n

  • Armarios, cajas y marcos de sellado para puertas<\/li>
  • Sellado de ventanas de equipos y paneles de gran tama\u00f1o<\/li>
  • Juntas de estanqueidad de contorno irregular en lotes peque\u00f1os<\/li><\/ul>\n\n

    Par\u00e1metros que deben confirmarse antes de la selecci\u00f3n del modelo<\/h3>\n\n

    Se recomienda facilitar la siguiente informaci\u00f3n antes de solicitar un presupuesto o una muestra, con el fin de reducir las repeticiones en la elaboraci\u00f3n de muestras y los malentendidos sobre las especificaciones.<\/p>\n\n

    • Forma de la secci\u00f3n transversal, per\u00edmetro y radio de curvatura<\/li>
    • Presi\u00f3n de sellado, tracci\u00f3n y condiciones de temperatura<\/li>
    • Aspecto, resistencia y tolerancias dimensionales de los racores<\/li><\/ul>\n\n

      Aspectos clave del dise\u00f1o estructural<\/h3>\n\n

      Es necesario evaluar de forma conjunta las dimensiones estructurales, las relaciones de montaje y la elasticidad de los materiales; por lo general, aumentar un par\u00e1metro por s\u00ed solo no mejora directamente la fiabilidad.<\/p>\n\n

      • Elegir entre esquinas en \u00e1ngulo recto, en bisel o moldeadas<\/li>
      • Las uniones se sit\u00faan lejos de las zonas de mayor tracci\u00f3n y de las juntas cr\u00edticas<\/li>
      • Longitud y diagonal del bastidor de control de posicionamiento de la plantilla<\/li><\/ul>\n\n

        Producci\u00f3n y control de calidad<\/h3>\n\n

        La uniformidad en la producci\u00f3n en serie se consigue mediante el control conjunto de los lotes de materiales, el estado de los moldes, la ventana de moldeo y los m\u00e9todos de inspecci\u00f3n.<\/p>\n\n

        • El corte debe ser liso y limpio, y hay que controlar la cantidad de pegamento.<\/li>
        • Realizar la uni\u00f3n t\u00e9rmica o la uni\u00f3n adhesiva utilizando un molde de posicionamiento<\/li>
        • Rectificar la uni\u00f3n sin alterar la secci\u00f3n transversal efectiva<\/li><\/ul>\n\n

          Elementos que se recomienda verificar<\/h3>\n\n

          Las pruebas de verificaci\u00f3n deben realizarse, en la medida de lo posible, en condiciones reales o equivalentes, y se debe volver a comprobar el funcionamiento tras el envejecimiento o los ciclos de prueba.<\/p>\n\n

          • Comprobaci\u00f3n de la resistencia a la tracci\u00f3n y al desgarro de las uniones<\/li>
          • Realizar pruebas continuas de estanqueidad al aire o al agua en estado de montaje<\/li>
          • Revisi\u00f3n de las grietas en las juntas tras el envejecimiento t\u00e9rmico y la compresi\u00f3n<\/li><\/ul>\n\n

            Preguntas frecuentes<\/h3>\n\n

            \u00bfSe puede sellar simplemente peg\u00e1ndolo con pegamento?<\/h4>\n\n

            A\u00fan es necesario verificar la compatibilidad de los materiales, la secci\u00f3n transversal de las uniones y la resistencia a largo plazo.<\/p>\n\n

            \u00bfEs mejor una uni\u00f3n en inglete de 45 grados que una en \u00e1ngulo recto?<\/h4>\n\n

            Hay que valorarlo teniendo en cuenta la secci\u00f3n transversal, las fuerzas aplicadas y la capacidad t\u00e9cnica.<\/p>\n\n

            \u00bfC\u00f3mo se facilita la informaci\u00f3n a los proveedores?<\/h3>\n\n

            Se recomienda facilitar planos en 2D o 3D, fotograf\u00edas de muestras, requisitos de materiales y dureza, entorno de uso, cantidad prevista, criterios de aceptaci\u00f3n y una lista de la documentaci\u00f3n de conformidad. Chengxin Silicone podr\u00e1 evaluar, en funci\u00f3n de esta informaci\u00f3n, los materiales, los moldes, el proceso de moldeo y el plan de verificaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
