Market Pulps
- The emergence of the Fourdrinier paper machine in 1799 spurred research and development into alternatives to linter fibers, the main raw material used until then in the manual production of paper and insufficient to feed these revolutionary giants.
- During the first half of the 20th century the pulp fibers were mainly sourced from softwoods (conifers) like pine and spruce.
- During the second half of the 20th century pulp fibers sourced from hardwoods (deciduous) like eucalyptus and birch appeared and transformed worldwide the pulp and paper industries.
- The main pulp production sites shifted from the northern hemisphere to the southern hemisphere, into huge plants capable of producing up to 2MTPY of market pulps in a single line.
Product for this application : Pulp Inspector
Pulp Inspector is the perfect tool for on-line quick, accurate and objective assessment of pulp fiber quality, being an unequable testing solution for several key areas :
- Pulp Inspector analyses the entire fibrous population in detail from a pulp furnish sample and accurately characterizes itp Inspector within minutes, bringing a significative and useful package of morphological results – fiber length, width, coarseness, fibrillation, curl, kink and wall thickness as well further fibrous elements like fines, shives and vessels
- Pulp Inspector is also capable of automatically producing laboratory handhseets which may be analysed by an ISO Brigthness Tester and by a NIR Spectrophotometer
- The several results from Pulp Inspector – full fiber morphology, ISO Brightness and Kappa – serve for quality control and product certification and for process control, such as active control the digester by adjustment of cooking parameters accordingly to the natural variations of wood supplies, preventing losses on fiber strength due to excessive cooking and preventing the occurrence of shives due to changes in wood chips quality

- Rugged – Pulp Inspector is built in a stainless steel cabinet for direct installation in production areas and its rugged and consecrated design requires basic maintenance care of a few regular wear parts
In Summary
Pulp industry in the XXIst century pursues actively sustainability, and Fiber Morphology, became mainstream for R&D and Quality Control of cellulosic materials thanks to unmatched accuracy, repeatability, and ease of use modern on-line fiber analyzers, which provide quickly and accurately a common analytical language between Process, Quality Control and R&D teams — enabling dynamic integration in the development, understanding and optimization of fibrous materials.
