Formation & Flocculation IndexPulp & Mill
Analyze pulp fiber lengths and slurry consistency to estimate flocculation risk and sheet formation uniformity.
Typical pulp fiber lengths: Softwood (2-3.5mm), Hardwood (0.8-1.4mm), Cotton (1-2mm), Hemp (4+mm).
Crowding factor measures the visual looked-through quality of formed sheets. High crowding means fibers coalesce, leaving patchy transparent and dense areas.
Formation assessment: Excellent Uniformity
Fibers disperse uniformly. High sheet strength consistency and outstanding look-through clarity.
