The purpose of this investigation was to study Eucalyptus species pulps and trying correlations between pulp yields and degree of delignification and pulp yields and wood density. The following conclusions could be drawn from the data analysis: A) there is an important influence of species on pulp yields at given degrees of delignification. B) it was noticed a linear pattern between total pupl yield and Kapa number, as far one species was concerned as well all together. C) the same pattern was verified for reject content. D) the linear relationship was observed for weighty pulp and volumetric pulp yields. E) no proportionality was observed between wieghty pulp yields and wood density. F) high correlation coefficients were noticed between volumetric pulp yieldsand wood density. So, one can assume that the morphological variations on the woods of different species were the major factor to avoid proportionality between wieghty pulp yields and wood density, but this influence was not strong enough to produce interference on the volumetric pulp yields and wood density relationship. |
