Definitions for "Semi-chemical pulp"
Keywords:  pulp, fibre, nssc, defibration, niche
Pulp produced in a two-stage process which involves the partial digestion of the wood with chemicals, followed by mechanical separation of the fibres in a disc refiner. As such it is a half-way stage between mechanical and chemical pulp. Semi-chemical pulp is used in niche applications, especially those which require fibre stiffness, e.g. in corrugating medium.
Pulp in which the fibres have been separated mechanically after a preliminary chemical treatment; e.g. NSSC pulp
A combination of chemical and mechanical pulping with properties similar to chemical pulp.
