摘　　要：研究了沙柳P-RCAPMP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-RCAPMP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73.78%,白度74.16%ISO,不透明度86.25%,光散射系数42.84m2/kg,裂断长3.62km,撕裂指数3.30mN.m2/g,耐破指数1.42kPa.m2/g。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.
