Description
This course begins with a thorough review of general chemistry principles. Following this, the chemistry associated with both pulping and papermaking is examined in depth. Kraft and sulfite pulping processes are reviewed, and as each unit operation is examined, appropriate analytical calculations are demonstrated. Polymer and carbohydrate chemistry are discussed prior to studying wet-end paper machine technology. Attention is then turned to concepts and applications of colloid chemistry to papermaking processes. The specific technology related to sheet formation, internal sizing, wet/dry strength resins and dyestuffs is explored. Other issues studied include foam control, pitch control, and first-pass retention performance on a paper machine. Prerequisites: CHE101 or CHE112, PPT111, PPT113, PPT115.
