Abstract
Se divulga un proceso de fabricacion de escamas, en donde: se provee una cámara de deposicion al vapor; se coloca un dispositivo de transporte en la cámarade deposicion al vapor; se provee una fuente de material de recubrimiento desprendible y una fuente de deposicion al vacío en la cámara de deposicionorientadas hacia el dispositivo de transporte, en el cual la fuente de deposicion deposita una capa de material para escamas; se aplica un vacío a la cámara, ymientras la cámara es evacuada, se aplican capas alternativas de un recubrimiento desprendible desde la fuente correspondiente y una capa de escamasdepositadas por vapor desde la fuente de deposicion al vacío al dispositivo de transporte en secuencia a efectos de obtener un sandwich multilaminar de capasde material para escamas y capas de recubrimiento desprendibles interpuestas, alternativas; en tanto las capas de recubrimiento desprendible comprenden unmaterial con capacidad de disolverse que forma una capa barrera continua lisay una superficie de soporte donde pueden configurarse las capas de material paraescamas, de modo que al retirarse el sandwich de la cámara evacuada se obtenga un sandwich multilaminar que puede ser fácilmente descompuesto en escamas de untamano de partículas fino mediante un tratamiento subsecuente con un material que esencialmente disuelve por completo las capas de recubrimiento desprendibleinterpuestas para separarlas de las escamas. Las escamas pueden estar recubiertas sobre ambas caras por capas poliméricas de proteccion aplicadas desde fuentesde deposicion al vacío adecuadas o similares instaladas en dicha cámara. El recubrimiento desprendible puede ser un material termosolidificado que esligeramente entrecruzado en la cámara de vacíoy posteriormente tratado con un material disolvente de despolimerizacion que rompe los enlaces químicos losuficiente como para separar las capas.A scale manufacturing process is disclosed, where: a steam deposition chamber is provided; a transport device is placed in the steam deposition chamber; a source of removable coating material and a source of vacuum deposition are provided in the deposition chamber oriented towards the transport device, in which the deposition source deposits a layer of scale material; a vacuum is applied to the chamber, and while the chamber is evacuated, alternative layers of a removable coating are applied from the corresponding source and a layer of steam-deposited flakes from the vacuum deposition source to the transport device in sequence in order to obtain a multilaminar sandwich of layers of material for flakes and interposed removable layers of coating, alternatives; while the layers of removable cover comprise a material capable of dissolving that forms a continuous smooth barrier layer and a support surface where the layers of flake material can be configured, so that when removing the sandwich from the evacuated chamber a multilaminar sandwich is obtained that it can be easily decomposed into fine particle size scales by subsequent treatment with a material that essentially completely dissolves the interposed removable coating layers to separate them from the scales. The scales may be coated on both sides by polymeric protective layers applied from suitable vacuum deposition sources or the like installed in said chamber. The removable coating may be a thermosolidized material that is lightly crosslinked in the vacuum chamber and subsequently treated with a depolymerization solvent material that breaks the chemical bonds sufficiently to separate the layers.
