| Popis: | RAPPT (Research Association of Pulp and Paper Technology) initiated its RDA : Fundamental research of fluid bahaviour of pulp suspension and evaluation of physical properties, printability coating-capability of HCF sample sheet.B : Search for the screen in the approach flow of HCF.C : Research on the sheet forming.-1 : Quick-sheet forming.-2 : Fiber dispersion and jet stability of the HCF head box.-3 : Fiber dispersion in the sheet forming zone.Assembling all the idea of the researchers, a pilot plant, available for various types of sheet forming test, was built in Oct., 1985.As for the sheet formation, printability and coating-capability, HCF sample sheet formed on the pilotplant could be evaluated as good as the conventionally formed one. However, the tensile strength, both of the machine and cross directions reduced gradually with the increasing consistency in the head box, whereas the Z-direction strength increased. |
