Pulp Bleaching Demonstration
"Self-guided, blended learning testing labs examining property measurements and variables."
Most pulps for Printing Papers and Tissue are bleached. Pulps for newsprint and some other grades are also bleached, but not to the same high levels of brightness. Linerboard can be bleached or unbleached.
Scope and Learning Objectives:
These self guided testing labs and video modules demonstrate the procedures used to test chips, pulping & bleach liquors and pulp. They will also provide some background about the property being tested. The overall learning objective is to increase your understanding of why and how these tests and procedures are performed.
The outline you should follow for each lab is to learn the background information on the property being tested, note the TAPPI standards that are referenced, then view the video on the correct testing procedure. Sample data is provided. Some of the labs will require calculations and analysis of data, and other labs will provide final data without calculations. A short set of thought questions is included at the end.
