Course Outcomes
1.
Work in teams to plan and conducts experiment involving pulp and paper manufacturing processes.
2.
Identify fibers using optical microscope and fiber staining techniques.
3.
Measure the freeness and consistency of pulp samples.
4.
Perform kraft cooks. Identify the major cooking variables and the effect of these variables on pulp yield
and kappa number.
5.
Perform kappa number tests and estimate pulp yields from typical kraft cooks.
6.
Perform a three stage bleaching sequence. Measure pulp brightness and viscosity. Identify the major
bleaching variables and the effect of these variables on pulp brightness and viscosity.
7.
Perform beater runs and develop a beater curve.
8.
Make Tappi standard handsheets from pulp beaten to different freeness levels.
9.
Measure following paper properties: basis weight, caliper, burst index, tensile index, tear index, air
permeability, brightness and opacity.
10.
Develop freeness vs. property curves.
11.
Make Tappi standard handsheets with different levels of filler addition and retention aids. Calculate single
pass filler retention for different cases. Identify the effect of filler levels and retention aids on the paper
properties.
12.
Prepare laboratory reports that clearly convey background information, experimental procedure, results,
discussion of results and conclusions according to the report format.
13.
Apply safety laboratory practices by adhering to safe work guidelines, adhering to specific lab operating
procedures and adhering to personal protection policies.
14.
Maintain a lab notebook and record data according to given guidelines.
