Mütek DFR-05 Drainage Freeness Retention
|Hãng sản xuất:||
The Mütek DFR-05 Drainage Freeness Retention simulates the retention and drainage conditions prevailing in an papermachine immediately before and during sheet forming, enabling a systematic assessment of chemical influences. Chemical addition is fully automated via an integrated dosing module. The optional RET-20 Lab sensor can also directly measure filtrate consistency, eliminating time-consuming manual determination of stock and ash consistencies.

The drainage behavior is characterized by gravimetry of the filtrate volume. Besides, the Schopper-Riegler freeness can be determined from which the Canadian Standard Freeness (CSF) may be calculated applying a correlation.
To ensure smooth production processes and high paper quality, an analysis of both retention and drainage is indispensable as they are Lac Viet Audio crucial parameters in paper production. The MütekTM DFR-05 Drainage Freeness Retention is designed to minimize efforts when Retention-Drainage-Formation trials need to be performed.
As fibers, fines and fillers are flocculated during the production process, the hydrated fiber layer is destroyed, which improves drainage of the pulp. These mechanisms are subject to a multitude of influential factors. Additives such as starch, dyes, optical brighteners, wet strength agents and retention aids enter into reactions with the fibers. In addition, process temperatures, shear forces and contact times play a major part. All these parameters ultimately impact PM runnability and paper quality.
