Study on Effort of Ultrasonic Treatment on Water Retention Value of Pulp Fiber
Advanced Materials Research, 2014Effects of ultrasonic processing conditions on water retention value of bleaching coniferous wood pulp fibers, absorbent cotton pulp fiber and straw pulp fiber were discussed. Results showed that ultrasonic power and processing time have an significant impact on water retention value of three kinds of pulp, the effort of ultrasonic treatment ...

The upper and middle reaches of the Hunhe River, with forest coverage rate up to 68%, is an important water source protection area in Liaoning Province. Based on the SWAT model and shadow engineering method, we aimed to estimate the function and service value of water retention in the upper and middle Hunhe River basin from 2000 to 2019, to analyze the

The underlying mechanisms of the recalcitrance of biomass to enzymatic deconstruction are still not fully understood, and this hampers the development of biomass based fuels and chemicals. With water being necessary for most biological processes, it is suggested that interactions between water and biomass may be key to ...

The water retention values of never‐dried alkali‐treated celluloses
Polymer International, 1993AbstractThe extent of swelling of refined and unrefined cotton linter, viscose pulp and paper pulp treated with various concentrations of NaOH from 4 to 20% at 20°C, then washed with water and never dried was measured in terms of the water retention values (WRV).

This study examined in detail the utility and validity of water retention value (WRV) for characterizing the extent of fibrillation of micro and nanofibrils. A bleached pulp fiber sample was either refined to different degrees using a PFI mill or milled for different time periods using a SuperMassColloider (SMC), to produce micro and nanofibril samples.

Processing of lignocellulosic biomass is complex due to the heterogeneity of the substrate, but also due to lengthy unit operations, which complicates process control including for enzymatic saccharification. Methods for predicting enzymatic saccharification yield based on the properties of the pretreated biomass would be advantageous to process ...

AbstractThis work conducted an investigation on the water retention value (WRV) of pulp fibers measured by the conventional centrifugation method (with a screen filter) and the maximum content of fiber bonding water (MCFBW) measured by a headspace gas chromatography (HS-GC), a method with no fine loss, developed recently. The results showed there is an

The recent changes on Brazilian specifications for Portland cement, in order to permit limestone additions, led to the necessity of knowing its influence in several aspects of the cement behavior when applied in civil construction. In this paper the rheological properties, basically yield point and plastic viscosity, are determined in ...
