“PITA’s Introduction to Modern Wet End Chemistry” Everything you need to know about Colloid Chemistry on a Paper Machine 2 nd & 3 rd July in the PITA Office (Bury)
Mark gained a PhD in Colloid Science from the University of Bristol and then spent a few years in the oil industry before joining and working ( for over 30 years ) in Paper Industry. Having gained experience at McMillan Bloedel Research, Mead Central Research, UK Paper and Omya, he has been involved in problem-solving around Wet End Chemistry on Paper Machines around the world. By measuring colloidal properties and using these measurements, it is possible to solve a wide range of papermaking issues.
Course Objective: Gain an understanding of how colloidal materials can be used and controlled to give you desired paper properties and improved paper machine efficiency.
Day 1—Morning: Understanding & measuring colloidal properties x What are colloidal materials How colloidal systems are stabilised & de- stabilised Measurements of colloidal properties & other related chemical properties Use of these measurements to improve paper machine operations Day 1—Afternoon: Use of inorganic colloidal solids - Fillers x Type of fillers used in paper making
Day 2—Morning: Use of colloidal material to give desired paper properties x Strength additives Nanocellulose, starch, wet strength & dry strength additives x Shade control, Dyes & OBAs x Surface modifications additives Wet end size, size press & coatings Day 2—Afternoon Control of colloidal material to improve paper machine efficiency x Control of undesirable colloidal materials Pitch, scaling & anionic trash x Improve retention of desired colloidal material Retention & drainage aids x Control of microbiological contaminants x Yankee dryer chemistry
