Abstract

Importing of wood has been considered as a solution to supply raw material in Iranian paper industry because of wood shortage. Therefore, the effect of mixing the imported ASPEN round wood with the two native hardwood forest species including hornbeam and beech on the optical and mechanical properties of CMP PULP was investigated. Cooking conditions consist of maximum temperature at 170oC with a liquor-to-wood ratio (L/W) of 7, and chemical content of 20% based on the oven-dry weight of the wood chips. CMP PULPs were prepared at different cooking times of 30 to 120 minutes using 20, 30, 40, 60, and 100% ASPEN wood in combination with the two species to achieve the yield of nearly 85%. Standard laboratory hand sheets were made after refining the pulp 300 ml CSF, and then the strengths and OPTICAL PROPERTIES were measured. Statistical analysis of the results showed that there were significant differences among the properties of CMP PULPs by increasing the ASPEN wood ratio. All the properties have been improved except opacity of the paper. The required strength of newsprint and printing/writing paper made in Mazandaran wood and paper industries (MWPI) could be achieved by mixing of 20 and 30% imported ASPEN wood to the NATIVE SPECIES currently used, respectively.
