Viscosity of Pulp 

"Self-guided, blended learning testing labs examining property measurements and variables." 

Lab Description:

Bleaching chemicals, and the pulping chemicals, have the potential to attack and damage individual fibers, decreasing strength. The strength of fibers is dependent on the structure and chemistry of the fibers, in particular the chain length (degree of polymerization) of the cellulose chains. Longer chains produce higher viscosities.

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 Standard (T230 and T254), or Useful Method 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.
