Untaught Experiences Regarding Common Practice and Standards for Sampling, Characterization, Control, and Design of TMP and CTMP Operations

摘要

1. Composite pulp samples collected during three minutes consisting of at least 20 grab samples. At least four composite pulp samples should be subsequently collected and included in the analysis. 2. Present standard for tensile index should be questioned: more strips and may be higher density level 3. Commonly used average length-weighted fibre length should be abandoned. Erroneous conclusions may otherwise be drawn. The average length-length-weighted fibre length is a relevant characteristic of the "length" factor.
