Papermaking Process Testing

Several characteristics of stock and water flows to and around a paper or board machine are often monitored and/or controlled. This module will cover pH, consistency, temperature, fiber size distribution, freeness, and charge demand testing.

•Explain the purpose of monitoring the pH, consistency, temperature, fiber size distribution, freeness, and charge demand of stock and white water flows to and around paper and board machines •Describe common papermaking process tests including what they measure •Define "first pass retention" and identify problems that can result from low retention values •Explain how the results of these tests can be used to optimize or ensure machine runnability or sheet quality •List safety hazards and safety guidelines associated with sampling and testing stock and white water systems
