Properties of OQPaP Bleached Pulp of Pinus kesiya and Dendrocalamus giganteus Munro Made by Low-Temperature Kraft Pulping

Abstract:

In this paper, the low-temperature (the maximum pulping temperature was less than 150°C) and conventional (the maximum pulping temperature was 165°C) kraft pulp of pinus kesiya and Dendrocalamus giganteus Munro were bleached by OQPaP. Then bleaching properties and paper properties of two kinds of bleached pulp were compared and evaluated respectively. The results showed that the strength indexes of the kraft pulp at low temperature were significantly higher than those of conventional pulp with lower viscosity.
