Abstract

SE REFIERE A UN PROCESO EN CUAL EL MATERIAL COMPRENDE UN LIQUIDO ACUOSO CON PARTICULAS DE SOLIDOS DISPERSOS, EL QUE ES BOMBEADO COMO FLUIDO Y DEJADO EN REPOSO PARA TOMAR UNA CONSISTENCIA RIGIDA QUE ES FAVORECIDA AL RETENER LA CAPACIDAD DE BOMBEO DEL MATERIAL COMBINANDO PARTICULAS POLIMERICAS CON EL MATERIAL DURANTE O ANTES DEL BOMBEO, DICHAS PARTICULAS POLIMERICAS COMPRENDEN POLIMERO HIDROSOLUBLE ANIONICO FORMADO A PARTIR DE UN MONOMERO HIDROSOLUBLE ETILENICAMENTE INSATURADO O UNA MEZCLA DE MONOMEROS QUE COMPRENDE MONOMEROS ANIONICOS SELECCIONADOS DE MONOMEROS DE ACIDO CARBOXILICO Y/O ACIDO SULFONICO ETILENICAMENTE INSATURADOS Y OPCIONALMENTE COMONOMEROS NO IONICOS PREFERENTEMENTE SELECCIONADOS ENTRE EL GRUPO QUE CONSISTE EN (MET)ACRILAMIDA, HIDROXIALQUILESTERES DE ACIDO (MET)ACRILICO Y N-VINILPIRROLIDONA. LAS PARTICULAS POLIMERICAS SE AGREGAN AL MATERIAL: 1) EN FORMA DE UNA EMULSION O DISPERSION EN FASE INVERSA, O COMO UNA DISPERSION EN UN MEDIO ACUOSO O COMO AGREGADOS FRIABLES ENLAZADOS DE PARTICULAS PRIMARIAS DE TAMANO DE PARTICULA INFERIOR A 10 MICRONES; O 2) COMO PARTICULAS SUSTANCIALMENTE INDIVIDUALES DE TAMANO DE PARTICULA SUPERIOR A 20 MICRONES. DICHO TRATAMIENTO SE REALIZA EN UN APARATO QUE COMPRENDE: A) UN MEDIO PARA EXTRAER LA SUSPENSIONDE UNA LINEA DE FLUJO; Y B) UNA CAMARA DE MEZCLADO QUE COMPRENDE: i) UNA PARED CIRCULAR; ii) UNA ABERTURA EN LA PARTE SUPERIOR Y EN LA BASE; iii) UN MEDIO PARA ADMINISTRAR EL QUIMICO; Y iv) UN MEDIO PARA TRANSPORTAR LA SUSPENSION
