本程序用于通过在实验室打浆机中对纸浆进行受控机械处理来确定纸浆的造纸质量；另见TAPPI T 248实验室打浆（PFI磨浆法）。打浆程序可用于任何纸浆，适当修改提取计划，以提供令人满意的打浆曲线所需的样品数量。对于某些超长纤维纸浆，如棉纤维或黄麻纤维，该方法可能不会给出令人满意的结果，因为纤维会缠绕在打浆机中，并倾向于缠绕在打浆机中。

This procedure is used to define the papermaking quality of pulp, by subjecting it to a controlled mechanical treatment in a laboratory beater; see also TAPPI T 248 Laboratory Beating of Pulp (PFI Mill Method).The beating procedure may be used with any pulp, suitably modifying the withdrawal schedule to provide the number of samples required for a satisfactory beater curve. The method may not give satisfactory results with certain extremely long-fibered pulps, such as cotton fibers or jute since the fibers entangle and tend to rope in the beater.
