| 摘 要： | 为适应短周期工业材制化学浆的需要，测定了１１年生马尾松的纤维形态、化学组成；研究了硫酸盐法蒸煮特性、漂白性能和强度性能，并和３０年生成熟马尾松相对照。结果表明：不同种源的１１年生幼龄马尾松的制浆性能比３０年生的虽差些，在漂白性能、打浆性能方面又稍优于后者。所以采用幼龄马尾松制浆造纸还是可行的。

| Abstract: | Fiber properties, chemical components and pulpabilities of four species of Juvenile MassonPine (Pinus massiniana Lamb. ) of 11 years old were .studied and a primary evaluation about pulpabilities was made. Compared with the nature Masson pine of 30 years old, the juvenile has shorter average fiber length, smaller length/width ratio, higher lignin content and similar holocellnlose content.With the same pulp-hardness (Kappa number 30), the juvenile requires higher alkali charge and woodconsumption. The juvenile's bleachabilities are nearly the same as the mature' by the common CEHbleaching process and with the same amount of chlorine. As a result, the juvenile cell wall is thinner,beatability better and fiber bonding higher. Their pulp pubesses the same breaking length and burst index as the mature's, but fear index is lower. |
