摘要
将APMP浆全组分和APMP浆长纤维组分分别与针叶木浆全组分以及针叶木浆短纤维组分进行配抄,研究纸张抗张强度、撕裂强度和内结合强度的变化规律,探讨APMP浆与针叶木浆组分配抄对纸张性能的影响.结果表明:APMP浆与针叶木浆全组分配抄的抗张强度、撕裂强度、内结合强度随着针叶木浆添加量的增大而增大,与短纤维组分配抄时纸张抗张强度、撕裂强度在15%处发生转折;而针叶木浆分别与APMP浆全组分和长纤维组分配抄时,抗张强度、撕裂强度随着针叶木浆添加量的增大而增大.此外,APMP浆配抄的纸张,其纤维长度和本身强度对纸张强度性能的影响较大.随着针叶木化学浆的增加,纸页的可压缩性提高,短纤维组分对强度有一定的贡献.
APMP pulp and the long fiber fraction of APMP pulp were used to prepare hand- sheets with the addition of chemical pulp （softwood pulp） and the short fiber fraction, re- spectively. Paper properties variation of softwood pulp applying to APMP pulp were re- searched by studying the variation of tensile strength, tear strength and internal bond strength of handsheets. The results showed that the tensile strength, tear strength and inter nal bond strength increased with the increasing the chemical pulp dosage when APMP pulp was used to prepare handsheets with the addition of softwood pulp. The tensile strength and tear strength of handsheest, which were prepared APMP pulp with short fiber content of softwood pulp, had a twist when the short fiber contents of softwood pulp were 15%. The tensile strength and tear strength increased with the increasing the chemical pulp dosage when APMP pulp and the long fiber fraction of APMP pulp were used to prepare handsheets with the addition of softwood pulp, respectively. Otherwise, the fiber length and strengthhad a great effect on paper properties, which was prepare handsheets with APMP pulp. The compressing of paper was increased with the increasing the chemical pulp dosage. The short fiber content of APMP pulp played a significant role in the strength of handsheets.
