Measuring concentration of sizing liquid in the preparation and size press
In papermaking, sizing provides paper a desired degree of resistance to water or other fluids and increases surface strength. Vaisala K-PATENTS® Process Refractometers are used for precise concentration measurement and control of sizing liquids in the internal sizing, surface sizing and coating processes.
The control applications are in:
Accurate concentration measurement ensures tight concentration specifications of the sizing liquids and helps to stabilize sizing conditions and paper quality.
The efficiency and safety of Kraft chemical recovery and fiberline and brown stock washing processes can be significantly improved by measuring in-line, real-time dry solids content. Download our application notes for more information.
