精致化纸浆模塑制品及关键制备工艺参数优化

为制备精致化纸浆模塑制品并研究关键加工工艺参数对其平滑度、光泽度的影响，以牛皮纸二次纤维为原料，在 全自动纸浆模塑机组上进行实际生产操作试验，用sPss软件进行极差分析和重复方差分析，对关键加工工艺参数进行 分析优化，得出较优的工艺参数为：打浆度25。SR、施胶剂用量1.5%、热压整型温度110℃和压力5 MPa。各参数影响 的主次顺序为：热压压力>打浆度>施胶剂用量>热压温度。研究表明提高热压压力，增加施胶剂用量，调节打浆度和 热压温度均可提高纸浆模塑制品的平滑度和光泽度

Refined Pulp Molding Products and Optimization of Process Parameters

In order to prepare fine pulp molding products and study the effect of their surface smoothness and gloss by the key process parameters. Using Kraft secondary fiber as raw material, the paper started the actual production operation test on automatic pulp molding machine. Range analysis and variance analysis were used to optimize the process parameters, the optimum process parameters were: pulp freeness 300SR; sizing amount l.5% ; temperature 110 0C ; pressure 5 MPa. The primary and secondary effect order of parameters was:the pressure > the pulp freeness > the amount of rosin > the temperature. The result showed that improving hot pressure, increasing the amount of sizing agent, adjusting freeness and pressing temperature could all improve the surface smoothness and gloss of molded pulp products.
