Pastas químicas soda-antraquinona de algumas essências nativas da Amazônia Brasileira, comparadas com polpas Soda-AQ de espécies papeleiras clássicas introduzidas na região

This paper show the results from research made of the wood family Moraceae, on its pulp qualities compared to classical pulp species for the production of pulp, throught the Soda-Aq process. Fisrtly, botanic, floristic, and sylviculture information was sought in the existing literature as to the wood researched as well as comparision. Determination of the chemical composition was made of all the species. Experiment were conducted of the fabrications of chemical pulp-Soda-Aq, for the grou of essences. Beaching oh the unbleached plp were made by the C.E.D.E.D., C.E.H.D.D, and D/C.E.D.E.D. process, for the pulps derived from all the woods involved in the research. Experiments of refining an the caracterization of its phsysical-mechanical properties of unuleached as well bleached pulp were conduct. Methodologies are described an the results discussed at the experiments. Various concusions can be inferred, from which ca be deduced that of the individuals of the family Moraceae researched, the Amapá and Imbaubarana can be considered as pulp species for reforestation.
