La perlite Randalite pr\u00e9sente une combinaison d’eau occluse, ce qui lui conf\u00e8re la propri\u00e9t\u00e9 exceptionnelle de se dilater lorsqu’elle est soumise \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es.<\/p>\n
La perlite expans\u00e9e, apr\u00e8s de d\u00e9licats processus de broyage et de classification, se transforme en un adjuvant de filtration dont les particules imbriqu\u00e9es peuvent former un g\u00e2teau incompressible, avec 80-90 % d’espaces creux, \u00e0 travers lequel passeront les liquides \u00e0 filtrer, en retenant les \u00e9l\u00e9ments solides en suspension, m\u00eame ceux de taille microscopique.<\/p>\n
La Randalite est utilis\u00e9e pour la filtration de liquides pharmaceutiques ou alimentaires, tels que le vin, le glucose, le sucre, la bi\u00e8re, les mo\u00fbts, les liqueurs, l’eau, les huiles et les produits pharmaceutiques en g\u00e9n\u00e9ral.<\/p>\n
La Randalite est une perlite particuli\u00e8rement adapt\u00e9e \u00e0 la r\u00e9alisation d’une pr\u00e9-couche coh\u00e9rente et facilement g\u00e9rable dans les filtres \u00e0 vide. Gr\u00e2ce \u00e0 sa faible granulom\u00e9trie, il permet d’obtenir des liquides d’une bonne propret\u00e9.<\/p>\n","protected":false},"excerpt":{"rendered":"
