Improvement of Pulping Uniformity by Measurement of Single Fiber Kappa Number [PDF]
, 2001 A method to measure the kappa of single fibers by staining with a fluorescent dye, Acridine Orange (AO), has been developed. This method is now applied to develop and automated flow-through instrument that permits routine kappa analysis on thousands of images of AO stained fibers to give the fiber kappa number distribution of a pulp sample in a few ...

Future global annual frozen ground distribution datasets based on Frost Number Model with Kappa coefficient [PDF]
Scientific DataPermafrost, which underlies roughly one-fifth of global land area, is highly vulnerable to ongoing climate warming and its degradation has important implications for hydrological processes, carbon cycling, ecosystems, and infrastructure stability.

Effect of alkaline extraction in reducing the Kappa number in ECF bleaching
, 2021 The acid hydrolysis stage (AHT) used in bleaching sequences of pulp, has as its main objective, the degradation of hexenuronic acids which are present in the pulp and can affect its brightness, reversal of brightness, among others. Despite the benefit of using the acid hydrolysis stage, the pH of this stage is not the most adequate, but when it comes ...

One Number, Two Names: kappa = tau = 0.9539
A short genesis note on a single empirically-anchored number, 0.9539, which appears in the author's prior work under two distinct labels: tau, the cosine-similarity rejection threshold in the Anti-Drift Cognitive Control Loop (ADCCL); and kappa, the Sovereign Invariant of Geometrically Ordered Dynamics (GOD Theory), which couples redshift-dependent ...

The effects of cooking parameters on the yield and Kappa number.
, 2012 Triticale (Triticosecale, Wittm. ex A. Camus) saplarından oksit ilaveli NaOH-O2 yöntemiyle optimum kağıt hamuru verim ve Kappa numarasını belirlemek için 27 adet pişirme denemesi yapılmıştır. Yapılan pişirme denemeleri sonucunda ekonomiklik de göz önüne alındığında pişirme sıcaklığı1200C, pişirme süresi 20 dakika, Al2O3 oranı %1, NaOH oranı %16 ...

Replacing imported long fiber pulp with kenaf bast fiber soda pulp to improve quality of paper made from bagasse soda pulp [PDF]
تحقیقات علوم چوب و کاغذ ایران, 2008 We studied the possibility of replacing imported long fiber pulp (ILFP) with kenaf bast fiber soda pulp (KBFSP) to improve the quality of paper made with bagasse soda pulp (BSP).

Effect of unbleached pulp Kappa number on the kinetics of chlorine dioxide delignification
, 2001 Chlorine dioxide delignification of different unbleached kraft pulps from Eucalyptus globulus, having Kappa numbers of 12 to 18, was studied in the temperature range of 285 K to 358 K. The effect of the unbleached pulp Kappa number on the initial fast phase of delignification was investigated with respect to the depletion factors for Kappa number and ...

The influence of pre-hydrolysis on the delignification of Hornbeam wood [PDF]
تحقیقات علوم چوب و کاغذ ایران, 2018 In this research, the influence of two temperatures (60 and 90°C) and three dosages of sodium hydroxide (5, 7.5 and 10%, based on the dry weight) on hornbeam wood chips alkaline pre-hydrolysis and soda pulping was studied.
