Abstract
This paper is introduced an adress on some critical evaluations of on-line measurement qualities in Pulp and Paper Industry which was given at 9th Automation and Instrumentation Symposium in October 7th 1985 sponsord by Japan TAPPI.
This lecture contains five contents as follows;
1. Science of fiber-water dispersion; a physical meanings of consistency in pulp suspension
2. Characteristic properties of pulp suspension by means of optical method; some analysis of optical properties of pulp suspension by gonio-photometer
3. Some problems to measure the degree of beating of pulp; on-line tester to evaluate the internal and external-fibrillation of beated pulps
4. Flocculation and formation; how to evaluate the formation of sheet
5. Measurement of electrokinetic effects in paper making processes; a demand of an instrument capable of automatic and continuous measurement and recording of the streaming potential
