Abstract

PROCESSO E DISPOSITIVO PARA CARREGAR FIBRAS OU CELULOSE CONTIDAS EM UMA SUSPENSãO COM UM MATERIAL DE ENCHIMENTO.A invenção se refere a um processo para carregar fibras (2.1) ou celulose (2.2) contidas em uma suspensão (3) com um material de enchimento (4) , por meio de uma reação de precipitação química, as fibras (2.1) ou acelulose (2.2) sendo fornecidas na forma de uma suspensão (3) com uma concentração sólida predefinida (c) . O processo inventivo é caracterizado pelo fato de dióxido de carbono(6) ser adicionado às fibras (2.1) ou à celulose (2.2) naforma de uma suspensão (3), enquanto que as fibras (2.1) oua celulose (2.2) sáo(é) misturada(s), de preferência em pelo menos um reator (5), com leite de cal ou cal extint(7) na forma de uma suspensão à qual diáxido decarbono (6) foi adicionado, iniciando e completando consideravelmente, de preferência inteiramente, a reação de precipitação química.PROCESS AND DEVICE FOR LOADING FIBER OR CELLULOSE CONTAINED IN A SUSPENSION WITH A FILLING MATERIAL. The invention relates to a process for loading fibers (2.1) or cellulose (2.2) contained in a suspension (3) with a filler (4). ), by means of a chemical precipitation reaction, the fibers (2.1) or acellulose (2.2) being supplied as a suspension (3) with a predefined solid concentration (c). The inventive process is characterized in that carbon dioxide (6) is added to the fibers (2.1) or cellulose (2.2) as a suspension (3), while the fibers (2.1) or cellulose (2.2) are (is) ), preferably in at least one reactor (5), with lime milk or extint lime (7) in the form of a suspension to which carbon dioxide (6) has been added, starting and completing considerably, preferably entirely. , the chemical precipitation reaction.
