摘    要:以PAGE方程为基础,结合光散射系数测量技术,提出了一种测量纤维间剪切结合强度的新方法,并以针叶木为原料,研究了打浆和湿压对纤维剪切结合强度和结合面积的影响。实验结果表明,打浆对纤维键合结合强度没有影响,提高湿压对剪切结合强度有增大作用;提高打浆度和增大湿压对纸页抗张强度的提高主要是纤维相对结合面积增大的结果。

关 键 词:纤维  剪切结合强度  结合面积  打浆  湿压

Abstract:Based on the PAGE equation and with the aid of light scattering coefficient measuring technique,a new method for determining fiber-fiber shear bond strength was presented in this paper.The effect of refining and wet pressing on fiber-fiber shear bond strength and sheet relative bonded area(RBA) was investigated with bleached Canada kraft softwood pulp.The results showed refining has no effect on shear bond strength and wet pressing can improve shear bond strength slightly,the increase of tensile strength through refining and wet pressing is ascribed to the RBA increase.
Keywords:fiber  shear bond strength  bonded area  refining  wet pressing
