    The laboratory pulp wet disintegrator is used for pulp disintegration treatment.
    The laboratory pulp wet disintegrator is a device used to simulate the industrial pulping process. It disperses pulp fibers into individual fibers or small fiber bundles through mechanical action, while simultaneously promoting fiber swelling and fibrillation, thereby providing standardized samples for subsequent performance evaluation.
    Application of Valley Beater in Pulp Laboratory Beating
    The Valley beater is a device used in laboratories to simulate industrial beating processes. It modifies the morphology of pulp fibers through mechanical action, thereby influencing paper properties. During operation, parameters such as beating pressure, pulp consistency, and beating time must be controlled, with the beating degree serving as a quantitative measure of the effect.
    Standard Method for Determining the Beating Degree of Pulp Using a PFI Mill
    This article introduces the standard method for measuring the degree of pulp beating using a PFI mill. The beating degree is a key indicator of the extent of pulp fiber processing and directly affects paper quality.
