Abstract

"USO DE SILICONES PARA FLUXO E TRANSFERêNCIA DE DISPERSõES DE PARTìCULAS DE SóLIDOS". A invenção refere-se ao uso de silicones de fórmula onde: R e R<39> são idênticos ou diferentes e representam um radical escolhido entre alquil C~ 1~-C~ 5~, aril; e x é um integrador compreendido entre 3 e 2000, para provocar ou facilitar o fluxo e a transferência de dispersões de partículas de sólidos em líquidos apresentando características de alta viscosidade ou alta resistência ao fluxo, em particular lamas de plantas de purificação de rejeitos civis ou industriais; pela adição às dispersões de uma quantidade de silicones variando entre 0,005 e 5% em peso com base no peso seco destas dispersões, estas últimas podendo ser transferidas por meio de bombas convencionais.
