Abstract

método e reator de produção em linha de carbonato de cálcio no processo de produção de uma trama fibrosa. a presente invenção refere-se a um método de e reator para produção em linha de carbonato de cálcio em um fluxo de suspensão alvo. o método e reator de acordo com a invenção são apropriados para introduzir e misturar leite de cal e dióxido de carbono em um fluxo de suspensão alvo de modo que os cristais de carbonato de cálcio formados durante sua reação não são permitidos precipitar sobre as paredes (12), do reator (10), porque o reator é dotado de meio (16, 18, 20) para evitar que os cristais de carbonato se fixem nas superfícies das estruturas localizadas na zona de reação.
