Tissue Making Process Testing

Several characteristics of stock and water flows to and around a tissue machine are often monitored and/or controlled for multiple reasons. This module will cover pH, consistency, temperature, freeness, and charge demand.

•Explain why stock and white water flows to and around tissue machines are often monitored for pH, consistency, temperature, fiber size distribution, freeness, and charge demand •Explain what these process tests 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 stock and white water systems
