Abstract

Un método de hacer papel kraft, especialmente con un gramaje de aproximadamente 50-140 g/m2, preferiblemente papel para sacos, como sacos con válvula, por ejemplo, para cemento, caracterizado porque comprende las etapas de someter una pasta al sulfato sólo a un refinado a alta consistencia (refinado HC) o a un refinado HC combinado con un refinado a baja consistencia (refinado LC), si se utiliza un refinado LC, manteniéndose el aporte de energía en conexión con el refinado LC en un valor por debajo de 80 kWh por tonelada de papel, calculado como papel 100 % seco, y añadiendo un agente que aumenta la resistencia, especialmente un polímero cargado, por ejemplo, almidón, a la pasta obtenida en esta conexiónenuno o más puntos distintos del proceso, antes de alimentar la pasta sobre la malla de una máquina de papel, de modo que la cantidad total de agente que aumenta la resistencia sea porlo menos8 kg (calculado como almidón) por tonelada de papel (calculado como papel 100 % seco).A method of making kraft paper, especially with a weight of approximately 50-140 g / m2, preferably paper for bags, such as bags with valves, for example, for cement, characterized in that it comprises the steps of subjecting a sulphate paste to only one high consistency refining (HC refining) or HC refining combined with low consistency refining (LC refining), if LC refining is used, keeping the energy supply in connection with LC refining at a value below 80 kWh per ton of paper, calculated as 100% dry paper, and adding an agent that increases the resistance, especially a charged polymer, for example, starch, to the pulp obtained in this connection in one or more other points of the process, before feeding the pulp on the mesh of a paper machine, so that the total amount of agent that increases the resistance is at least 8 kg (calculated as starch) per ton of paper (calculated as 100% paper is co).
