Abstract
PROCESSO PER LA PRODUZIONE DI CARTA E CARTONE, CHE COMPRENDE AGGIUNGERE ALL'IMPASTO DI CELLULOSA UN AMIDO MATURALE ED UN SALE DI ALLUMINIO E/O FERRO L'IMPASTO DI CELLULOSA COSI' OTTENUTO VIENE QUINDI SOTTOPOSTO A DRENAGGIO E SUCCESSIVA CALANDRATURA SECONDO TECNICHE CONVENZIONALI. IN TAL MODO LA RITENZIONE DELL'AMODO NATURALE SULLE FBRE DI CELLULOSA VIENE CONSIDEREVOLMENTE AUMENTATA, FINO A LIVELLI COMPARABILI A QUELLI OTTENIBILI CON UN AMIDO CATIONICO. PER AUMENTARE ULTERIORMENTE LA RITENZIONE RISULTA PARTICOLARMENTE VANTAGGIOSO PRE-MISCELARE L'AMIDO NATURALE CON IL SALE DI ALLUMINIO E/O FERRO, E QUINDI AGGIUNGERE LA MISCELA RISULTANTE ALL'IMPASTO DI CELLULOSA.
