| 摘 要： | 研究了沙柳P—RC APMP浆料性能的影响因素，并且从沙柳成浆后的纸浆白度，光学性能和纸浆强度出发，提出了沙柳P-P．CAPMP浆适合的化学预处理工艺条件。沙柳P—RcAPMP浆采用的化学预处理条件：NaOH用量8％、H2O2用量10％、处理温度60℃、时间40min、液比1：4，此时纸浆的白度和物理强度最佳，得率较高。纸浆得率75．78%，白度74．16％ ISO，不透明度86．25％，光散射系数42．84m2／kg，裂断长5．62km，撕裂指数3．30mN·m2／g，耐破指数1．42kPa．m2／g。

| Abstract: | The factors affecting the properties of the salix psammophila P-RC APMP were studied and suitable pulping conditions for salix P-RC APMP were presented in this paper from the point of a high brightness, optical properties, and pulp strength. The pretreatment conditions of salix P-RC APMP were as follows： NaOH charge 8%, H202 charge 10%, pretreating temperature 60℃, holding time 40min, liquid ratio 1：4. At this time the brightness and pulp strength were the best, the pulping yield was higher. The pulping yield is 73.78%, brightness 74.16%ISO, opacity 86.25%, light scat- tering coefficient 42.84 m2/kg, breaking length 3.62 kin, tearing index 3.30 mN.m2/g, burst index 1.42 kPaom2/g. |
