Abstract

Une galette de déshumidification (3) est décrite, comprenant un gel de silice (SiO2) et un adhésif (2) à base d'eau, le gel de silice (SiO2) étant broyé pour former une micro-poudre absorbante (1) avec une granulométrie comprise entre 25 et 500 mesh (env. 710 µm à env. 31 µm), puis étant mélangé intimement à l'adhésif (2) à base d'eau selon un rapport en poids de 80% à 98% en poids : 20% à 2% en poids en vue d'une mise en forme prédéterminée par moulage et, séquentiellement, d'un processus de cuisson et d'un processus de refroidissement, afin de former une galette de déshumidification (3) préformée, ayant une pluralité de pores (21). L'invention concerne également le procédé correspondant.A dehumidifying wafer (3) is described, comprising a silica gel (SiO2) and a water-based adhesive (2), the silica gel (SiO2) being ground to form an absorbent micro-powder (1) with a particle size of between 25 and 500 mesh (approx. 710 µm to approx. 31 µm), then being intimately mixed with the water-based adhesive (2) according to a weight ratio of 80% to 98% by weight: 20% to 2% by weight for a predetermined shaping by molding and, sequentially, a baking process and a cooling process, in order to form a preformed dehumidifying wafer (3) having a plurality of pores (21). The invention also relates to the corresponding method.
