Influencia del calcio en la retención de humedad por arcilla

ABSTRACT Bentonite as a raw material is an economical alternative to produce desiccants. The literature indicates that it is a good water adsorbent in relation to the desiccants commonly used in industry (silica gel, molecular sieve). In this sense, it is a valid alternative and an economic option since the clay is a natural compound, which makes it environmentally friendly. In this way, it is possible to protect products from moisture with the addi-tional advantage that its desiccant capacity remains practically constant after successive cycles of adsorption - regeneration, using low temperat...
