Abstract
"AGENTES DE REMOçãO DE ESPUMA E/OU DE EXAUSTãO, E, USOS DOS MESMOS, E DE UMA MISTURA". Agentes de remoção de espuma e/ou de exaustão à base de dispersões óleo- em- água, cuja fase oleosa contém pelo menos um composto a partir do grupo dos álcoois com pelo menos 12 átomos de carbono, álcoois graxos alcoxilados, monoglicerídeos, diglicerídeos e triglicerídeos de ácidos graxos, ésteres de ácido graxo de ácidos carboxílicos com pelo menos 12 átomos de carbono e álcoois monovalentes e trivalentes com de 3 a 22 átomos de carbono, hidrocarbonetos com um ponto de ebulição acima de 200<198>C, ácidos graxos com de 12 a 22 átomos de carbono, 3-tiaalcan-l-óis, 3-tiaoxidalcan-l-óis, 3-tiadioxid-alcan-óis e ésteres dos compostos tiaalcano em combinação com (i) pelo menos um éster de poliglicerina, que é obtido através de esterificação de pelo menos 20% de poliglicerina com um ácido carboxílico que apresenta de 12 a 36 átomos de carbono, e (ii) pelo menos uma bisamida que consiste de etileno diamina e ácidos carboxílicos contendo de 10 a 36 átomos de carbono e cuja fase aquosa contém pelo menos um estabilizador, água e eventualmente um agente de espessamento, para meios aquosos, que tendem à formação de espuma e ao uso de agentes de remoção de espuma e/ou de exaustão para o combate de espuma de meios aquosos que tendem à formação de espuma, em especial para o combate da espuma quando do cozimento de celulose, lavagem de celulose, moagem de polpa de papel, produção de papel e dispersão de pigmentos para a produção de papel.
