The influence of consistency and fibre length on the yield stress of OCC pulp fibre suspensions
BioResources, 2017 The effect of fibre length on the yield stress of recycled old corrugated containers (OCC) pulp fibre suspensions was investigated. Two types of OCC pulps were divided into four fractions based on the fibre length with a Bauer-McNett classifier. The yield stress of each fraction was measured using the shear stress ramp method at pulp consistency ...

Effect of Lactase Enzyme on Delignification and Physical Properties of OCC Pulp
Iranian Journal of Wood and Paper Industries, 2013 Old Corrugated Container (OCC) recycled pulp provided by a local paper manufacturing company was treated by lactase enzyme. The pulp was sampled from headbox and treated by enzyme in the conditions of consistency 2%, pH 5, reaction time 2 hours, and reaction temperature 60 °C in dosing levels of 0.005, 0.01 and 0.015 % based on oven-dried weight of ...

Investigating the effect of pH on cellulase enzyme efficiency on the OCC pulp properties
تحقیقات علوم چوب و کاغذ ایران, 2018 The purpose of this study is to investigate the effect of pH on cellulase enzyme activity on the drainage and strength properties of OCC pulp. Recycled OCC pulp was pretreated with consistency 0.4 percent, in constant condition the temperature is 50˚C, duration 1 hour and range pH:4-4.5, 8-8.5 with cellulase enzyme at three levels 0.1, 0.3 and 0.5 ...

The influence of OCC pulp refining to improve the properties of test liner board
تحقیقات علوم چوب و کاغذ ایران, 2013 The possibility to improve the test liner board properties using mechanical treatments (refining) was studied. Old Corrugated Container (OCC) fibers used in a recycled paper manufacturing company were quantitatively and qualitatively analyzed and hardwood and softwood fibers content were estimated as 22.6% and 60%, respectively.

Comparative Investigation of the Effect of Pre and Post -Enzymatic Refining on OCC Pulp Properties
تحقیقات علوم چوب و کاغذ ایران, 2014 In this research, the effect of different steps of enzymatic treatment including enzymatic pre-refining and post-refining by Endoglucanase was investigated on the quality of OCC pulp. Three pulps including a: control sample (without enzyme addition), b: enzymatic pre-refining (enzyme treatment + refining) and c: pre and post enzymatic refining (enzyme +
