Virtual Training Course
MODULE 1: PULP AND PAPER INDUSTRY OVERVIEW
Presenters: Nafty Vanderhoek and Russell Allan
MODULE 1 - VIDEO
Presentation: Module 1
The Australasian pulp and paper industry has had a long and proud history ever since its initial beginnings in the early nineteenth century, often punching well above its weight. This module will cover a historical timeline of major paper innovations and how the local industry, in common with its overseas counterparts, has had to continually adapt to an ever-changing landscape that is continuing to this very day.
This module also presents a review of the wide range of applications where paper is used in our society.
• Describe the major historical technical innovations and their importance to the industry
• Explain the industry’s fundamental role in the economy and why the industry should be supported
• List the proud past achievements of the local industry
• Describe the decades of change and who are now the major players
• Identify the new opportunities within the bioeconomy
• Understand paper’s ‘strengths’ and limitations.
• Explore and understand the properties paper must exhibit to be successful in a chosen application.
MODULE 2: FIBRE AND PULPING BASICS
Presenters: Nafty Vanderhoek
MODULE 2 - VIDEO
Presentation: Module 2
Fundamental to the pulp and paper industry is the availability of raw materials which are numerous and differ in their basic properties. Equally important are the methods to process these materials that also vary in their aims and outcomes. This module will describe the different fibre sources available to the industry and how they are best treated to achieve the desired end result.
• Describe the different wood types and their structural features
• Define the different chemical classes in wood and their main functions
• List the different pulping processes and how they differ from one another
• Explain the role of recycled fibre and its importance overall
• Describe other key process steps that make up part of the pulping value chain
MODULE 3: PAPERMAKING AND PAPER TREATMENTS
Presenters: Russell Allan
MODULE 3 - VIDEO
Module 3a - Papermaking
Module 3b - Paper Treatments
Paper is a high-tech composite material that lends itself to modification and design with the aim of sustainability and reuse. The performance of paper in a chosen application is controlled by not only the raw materials making up the paper but also the paper making process used and the various treatments that can be applied to the paper to improve, augment and modify its properties. This module will describe the fundamental processes central to paper making, the technologies that are used (and their evolution over time) and the treatments that are applied during manufacture.
• Appreciate the major process aims in paper making manufacture
• Describe the different approaches needed when using virgin or recycled fibre furnish
• Describe the process equipment utilised in the preparation of fibre delivered to the paper machine (the paper machine approach system)
• List and describe the process stages employed on commercial paper machines
• Describe the most important paper treatment processes used in paper manufacture
• Explain the operation of size press, speed sizer, coaters, calenders and creping systems
• Explain the effect on paper property each of the treatments seek to provide.
MODULE 4: PAPER PRODUCTS AND PAPER QUALITY
Presenters: Nafty Vanderhoek and Russell Allan
MODULE 4 - VIDEO
Module 4a - Paper Products & Quality
Module 4b - End user performance
Paper and board products are usually characterized and sold on the basis of standardised product grades and testing procedures with the prime objective to ensure all parties speak the same language when discussing paper or board products and test values. This module will cover the factors influencing paper and board properties and their end use requirements, the key issues associated with measurement and some common test methods.
• Describe what is meant by standardised methods
• Explain the difference between sensitivity, precision and accuracy in testing
• Explain paper directionality and how moisture impacts on paper properties
• Define the hysteresis effect and why conditioning of paper and board is critical
• List the common paper tests including what they measure and traps for beginners
• Explore the paper performance requirements for sack, packaging and communication papers
• Define and list the requirements for the two major applications for corrugated board packaging; containment and stacking.
