Quality Control
Tests on Pulp 1. pH Testing It’s measured by digital pH-meter for process control purposes. 2. Freeness Test The freeness of pulp is the rate at which a dilute suspension of pulp may be drained. The freeness, or drainage rate, has been shown to be related to the surface conditions and swelling of the fibers. Tests on Input Material 1. Purity Testing Measures the purity of chemicals and additives by means of chemical and physical methods. 2. Water Analysis Measures the pH, hardness and dissolved solids of the water which is consumed both in boilers and production process.
