Abstract:
(EN) The present invention provides methods for producing exfoliated clay platelets from a swellable clay material. In embodiments, the method for producing exfoliated clay platelets includes providing an exfoliating agent comprising an anionic extractant, and exposing the swellable clay material to the exfoliating agent, wherein the exfoliating agent produces exfoliated clay platelets from the swellable clay material. Methods for treating paper precursors and paper sheets are also disclosed, as are paper products formed from such paper precursors or paper sheets.
(FR) La présente invention concerne des procédés de fabrication de plaquettes d'argile exfoliée à partir d'une matière argileuse gonflable. Selon des modes de réalisation, le procédé de fabrication de plaquettes d'argile exfoliée comprend la fourniture d'un agent exfoliant comprenant un agent d'extraction anionique et l'exposition de la matière argileuse gonflable à l'agent exfoliant, l'agent exfoliant produisant des plaquettes d'argile exfoliée à partir de la matière argileuse gonflable. L'invention concerne également des procédés de traitement de précurseurs de papier et de feuilles de papier, ainsi que des articles en papier fabriqués à partir de ces précurseurs de papier ou feuilles de papier.
