Equipo de mezcla para pigmentos y colorantes de Deyue: mezcladoras de cinta, cinta-paletas, doble eje y cónica para color uniforme, bajo polvo y opciones ATEX.

Del dióxido de titanio al óxido de hierro y la ftalocianina, los pigmentos en polvo exigen una mezcla que dé color uniforme sin romper aglomerados ni generar calor. Deyue suministra sistemas de mezcla para pigmentos diseñados para una consistencia cromática alta (< 0,5 % de variación) y una manipulación segura de polvos finos y pulvurulentos.

Retos habituales en la mezcla de pigmentos

  • Aglo: las partículas submicrónicas se reagrupan; la intensidad debe romper los grumos sin sobre-moler.
  • Uniformidad de color: el tono final depende de una dispersión homogénea de pequeños lotes de color en grandes bases.
  • Polvo y riesgo de explosión: los pigmentos orgánicos son combustibles; importan el confinamiento y las opciones ATEX.
  • Contaminación: el arrastre entre lotes arruina el tono; una limpieza rápida es esencial.
  • Sensibilidad al cizallamiento: algunos pigmentos tratados se degradan con cizallamiento alto.

Mezcladores Deyue recomendados para pigmentos

Para producción en volumen, la mezcladora de cinta DLH ofrece lotes económicos y repetibles de 35 L a 15 m³. Cuando dominan los aglomerados, la mezcladora de cinta y paletas DPH añade acción intensiva que dispersa los grumos y alcanza < 0,5 % CV. Las líneas de ciclo rápido usan la mezcladora de doble eje DJH, con variante continua (DJHX) para toneladas. Los lotes sensibles al cizallamiento se mezclan suavemente en la mezcladora cónica de tornillo DSHL, y el laboratorio o I+D usa la mezcladora de laboratorio DEH.

Sistemas auxiliares: alimentación, transporte, envasado

Una línea cerrada de bajo polvo empareja la mezcladora con una estación de vaciado de sacos, transporte por vacío o sinfín y envasado en sacos válvula. La captación de polvo en cada punto de transferencia mantiene el tono limpio y el puesto seguro.

  1. Vaciado de sacos con captación de polvo.
  2. Pesado y carga en la mezcladora.
  3. Mezcla hasta la homogeneidad deseada (8-15 min típico).
  4. Secado opcional en la mezcladora de vacío DRH.
  5. Transporte y envasado en sacos válvula o FIBC.
