This practical and essential overview of rosin sizing introduces the concepts necessary to solve sizing-related problems commonly encountered in the mill. The program includes interactive quizzes to reinforce learning.
The rosin sizing problem deals with unexpected loss of sizing in a bleached cupstock mill. Using an interactive research section along with TAPPI’s six-step problem-solving approach, participants will learn the principles of rosin sizing and investigate possible solutions for the sizing loss problem.
Learning Outcomes:
Upon successful completion of this course, participants should be able to:
* Describe the types of rosin size and the function of sizing in general
* Recognize the differences between paste soap sizes and dispersed rosin sizes
* Explain the role of alum in rosin sizing operations
* Identify and analyze possible causes of sizing loss
Specific topics include: reasons for sizing, requirements for an internal size, effects of additives, types of rosin size, wet end differences, size and alum, size testing techniques, and synthetic sizes.
Rosin Sizing contains 3 to 4 hours of instruction and was developed and reviewed by Bill Scott, Ben Thorp, Kasy King, Joe Wilson, Steve Boone, Jerry Gess, and Michael Breslin.
