Abstract

"PROTEìNAS E POLìMEROS PARA USO COMO AGENTES CONTROLADORES DE PITCH E STICKIES EM PROCESSOS DE FABRICAçãO DE POLPA E PAPEL". Descreve-se métodos para inibir a deposição de contaminantes orgânicos de sistemas de fabricação de polpa e papel. Proteínas de soro do leite ou uma combinação de uma proteína e um polímero catiónico são adicionadas à polpa ou aplicadas sobre superfícies suscetíveis a deposição de um sistema de fabricação de papel.
