Abstract
Tr en Bu çalışmada, Sarıçam (Pinus sylvestris L.) ve Titrek Kavak (Populus tremula L.) odunundan Sülfat (Kraft) yöntemiyle aynı koşullarda kâğıt hamuru ve deneme kâğıtları üretilmiştir. Literatür araştırması yapılıp, yonga/çözelti oranı 1/4, pişirme sıcaklığı 170±2 °C, maksimum sıcaklığa ulaşma süresi 90 ve 75 dakika sabit alınarak; (Kraft) yöntemi ile aktif alkali/sülfitide oranı, 18/25 oranında pişirmeler yapılmıştır. Elde edilen hamur ve kağıtların bazı özelliklerinde önemli farkların ortaya çıktığı sonucuna varılmıştır. Özellikle, Titrek kavak odunundan elde edilen hamurun elenmiş verimi (%53,72) Sarıçam odunundan elde edilen hamurdan (%42,015) yüksek olduğu görülmektedir. In this study, paper pulp and test papers were produced under the same conditions as Sulfate (Kraft) method from Scots Pine (Pinus sylvestris L.) and Aspen (Populus tremula L.) wood. Literature research was conducted to determine the chip / solution ratio as 1/4, the cooking temperature as 170 ± 2 ° C, the maximum temperature reaching time as 90 and 75 min. (Kraft) method, the ratio of active alkali / sulfite was 18/25. As a result, significant differences in certain properties of the resulting pulp and paper have arisen. In particular, it is seen that the yield of the pulp yield obtained from the aspen wood (53,72%) is higher than that of the pulp yield (42,01%) obtained from the Scots pineKeywords
