Abstract
UN METODO DE REDUCIR LA CONCENTRACION DE BREA EN OPERACIONES DE REDUCCION A PASTA Y FABRICACION DE PAPEL, PARTICULARMENTE EN PASTAS PAPELERAS PRODUCIDAS POR PROCEDIMIENTOS DE PULPACION MECANICA QUE CONTIENEN PASTA DE MADERA EN CANTIDADES MAYORES QUE APROXIMADAMENTE 10% EN PESO, METODO QUE COMPRENDE AÑADIR A UNA PASTA PAPELERA QUE CONTIENE BREA UNA SUSTANCIA DE MATERIAL COMPUESTO EN FORMA DE PARTICULAS, DISPERSABLES EN AGUA Y ESTABLE, PREPARADA ABSORBIENDO IRREVERSIBLEMENTE UN POLIMERO CATIONICO SOLUBLE EN AGUA SOBRE UN SUSTRATO EN FORMA DE PARTICULAS ESENCIALMENTE INSOLUBLES EN AGUA, POR EJEMPLO CAOLIN, SIENDO EL POLIMERO CATIONICO SUFICIENTEMENTE ELECTROPOSITIVO PARA QUE LA SUSTANCIA DE REPRESION DE BREA DE MATERIAL COMPUESTO EN FORMA DE PARTICULAS EXHIBA UN POTENCIAL ZETA DE AL MENOS APROXIMADAMENTE 0 MV, Y PREFERIBLEMENTE DE ALREDEDOR DE 0 MV A ALREDEDOR DE +80 MV. APLICACION A INDUSTRIA PAPELERA.
