Abstract
Método de tratamiento de láminas complejas, de las que comprenden al menos una primera lamina simple de un polímero, preferentemente de PET, una segunda lámina simple de un polímero, preferentemente de PE, y al menos una capa de adhesivo, preferentemente EVA o acrílico. Las láminas se presentan en forma de escamas y se separan sometiéndolas a un primer baño de agitación en agua caliente con al menos un ácido dicarboxílico y al menos un ácido graso, preferentemente ácido oxálico y ácido oleico; más un segundo baño de agitación con un agente cáustico, preferentemente sosa cáustica, y un agente tensoactivo. Las láminas de PE y PET se separan mediante al menos un baño de densado. Las láminas de PET se tratan a continuación mediante un baño de agitación, un silo de secado y una máquina de separación de partículas extrañas. Tras cada baño, excepto entre los dos baños de densado, se pasan las escamas por una centrífuga.
