DETERMINATION OF PRACTICAL PROPERTIES OF ALNUS GLUTINOSA GROWN AT SHORT ROTATION PERIOD IN PAPER MAKING
In this investigation, physical, chemical, fiber dimensions, pulp and papermaking characteristics of 4 years old Alnus glutinosa was researched. The average of oven dry and critical density, fiber length, fiber diameter, lumen diameter and cell wall thickness were measured at 0.396, 0.368, 0.875mm,...

| description | In this investigation, physical, chemical, fiber dimensions, pulp and papermaking characteristics of 4 years old Alnus glutinosa was researched. The average of oven dry and critical density, fiber length, fiber diameter, lumen diameter and cell wall thickness were measured at 0.396, 0.368, 0.875mm, 32.66um, 27.28 urn and 2.70 urn respectively. Chemical compositions were obtained 48.5% cellulose, 25.35% lignin, 0.31% ash and 2.36% extractives. CMP, one stage APMP and two stage APMP processes were used for cooking. After preliminary cooking, cooking temperature, cooking time, NaOH and H202 charges were applied at 95 degree of centigrade, 10, 20, 30 and 40 minutes 10%,3% and so on. In CMP process, the average of yield, burst index, breaking length, tear index opacity and brightness were obtained at %73.72-%82.57, Kpa m2/gr. 1.53, Km 3.81, mNm2/gr 3.34, %99.59 and %29.35 correspondingly.In one stage APMP process, the average of yield, burst index, breaking length, tear index opacity and brightness were obtained at %74.09-%81.57, Kpa m2/gr. 1.52, Km 3.5, mNm2/gr3.2, %99.80 and%28.21 respectively.In two stage APMP process, the average of yield, burst index, breaking length, tear index opacity and brightness were obtained at %73.99-%80.89, Kpa m2/gr. 1.92, Km 3.95, mNm2/gr 3.45, %99.85 and %32.41 in that order.Among yields of pulp in the three methods, there weren't significant difference at level 5%. In two stages APMP paper, the burst index, breaking length and brightness were more than other and changes of cooking methods hadn't significant differences at level 5% on tear index. |
