超声波杨木浆在壁纸原纸中的应用研究

Study on the Application of Poplar Ultrasonic Pulp in Wall Paper's Base Paper

分析了杨木化学机械浆、超声波杨木浆和松木硫酸盐浆的纤维与纸张性能,并利用扫描电子显微镜分析3种浆料纤维形态,以松木硫酸盐浆与超声波杨木浆为原料,按照一定浆料比例混合并加入不同用量的PAE、滑石粉、AKD、CPAM,探究了其对纸张性能的影响。结果表明,当松木硫酸盐浆与超声波杨木浆比例为60∶40、PAE用量0.7%、滑石粉用量15%、AKD用量0.5%、CPAM用量0.2%时,可以实现壁纸原纸在光学、强度、吸收性能及尺寸稳定性符合要求的前提下降低生产成本。

The properties of poplar chemimechanical pulp,poplar ultrasonic pulp and pine kraft pulp were tested and compared by SEM.Using pine kraft pulp and poplar ultrasaonic pulp as fiber raw material to manufacture the base paper of wall paper,the influences of proportion of pine kraft pulp and poplar ultrasonic pulp,the usage of fillers and additives on the properties of the base paper were investigated.The results showed that the poplar ultrasonic pulp kept 40%,the optimum dosages of PAE,talc,AKD and CPAM were respectively 0.7%,15%,0.5%and 0.2%could reduce production cost of the base paper while its properties of optical,strength,absorption and dimensional stability could meet the requirements.
