The Effect Of Viscosity In Beveled Blade Coating, Salih Cebe
The Effect Of Viscosity In Beveled Blade Coating, Salih Cebe
Masters Theses
The objective of this study was to investigate the effects of several types of coating viscosity on coat weight development during the beveled blade coating process. In this study, the effects of several types of coating viscosity were experimentally investigated at the applicator roll, before and underneath the blade. Coating color viscosities were changed through two methods. The first method involved changing the temperature of coating color at constant carboxymethylcellulose (CMC) concentration, while the second method consisted of varying the CMC concentration in coating formula at constant coating temperature.
Coating viscosity had an influencing effect both on the amount of …
The Slip Velocity Of Coating Formulations Using The High-Shear Viscometer, Daniel Parker Krieger
The Slip Velocity Of Coating Formulations Using The High-Shear Viscometer, Daniel Parker Krieger
Masters Theses
When using a cup and bob viscometer, it has long been recognized that errors in the viscosity measurement can arise from several factors, among them slip. Slip is a phenomenon which occurs when there are slipping layers in the fluid under shear, causing a non-uniform velocity gradient to be generated across the gap of the cup and bob viscometer. A layer of fluid at either the bob or cup wall moves faster than the adjoining layers, causing the slipping effect. This leads to a low viscosity calculation for the fluid.
In this study, experiments with coating formulations were conducted using …

Using Thermophilic Bacteria To Produce Enzymes For Wood Pulping, Robert A. Debelak Jr.
Using Thermophilic Bacteria To Produce Enzymes For Wood Pulping, Robert A. Debelak Jr.
Paper Engineering Senior Theses
The objective of this Senior Thesis Project was to determine if thermophilic (heat loving) bacteria are capable of producing enzymes to break down lignin. Currently known ligninases produced by white-rot fungi are destroyed by high temperatures, and are only useful for pre-treatments in refiner mechanical pulping. Thermophilic lignin-degrading enzymes could potentially be useful in a high temperature pulping process.
Milled wood lignin was isolated from birch to be used in bacterial cultures. The lignin would serve as the only source of carbon for the bacteria, so their growth would depend on their ability to utilize the lignin for food. Standard …
The Effects Of Drying Conditions On The Properties Of Fines, Douglas A. Schuelke
The Effects Of Drying Conditions On The Properties Of Fines, Douglas A. Schuelke
Paper Engineering Senior Theses
This project was designed to study the impact of drying on the properties of fiber fines. Three different drying conditions were used: force-dry (0% moisture), force-dry (6% moisture), and air-dry (6% moisture). Fines were evaluated in the paper and in the pulp both before and after recycling.
In order to study the impact of drying on the fines, fines were removed from the virgin furnish. Characteristics of the control stock containing fines and of the control stock without fines were evaluated and served as a means of comparison. Stocks were tested for wet-web strength, drainage, freeness, and water retention value. …
An Examination On The Effect Of Ph On Flotation Deinking Kinetics, Brian R. Moran
An Examination On The Effect Of Ph On Flotation Deinking Kinetics, Brian R. Moran
Paper Engineering Senior Theses
This study was performed to determine if the flotation deinking process is first order with respect to ink particle concentration and to examine the effects that pH may have on the kinetics of ink removal flotation. A Hallimond tube laboratory flotation device was used to examine the process. Image analysis of ink particles was used to obtain quantitative results regarding flotation efficiency.
The examination verified that the flotation process follows the first order rate equation with some degree of experimental error. A trend in the effect of pH on deinking rate was also found. It was determined that the rate …
Utilization Of Paper Mill Primary Sludge, Daniel D. Schultz
Utilization Of Paper Mill Primary Sludge, Daniel D. Schultz
Paper Engineering Senior Theses
Recyclable fines and filler contribute to approximately one half the primary sludge stream, and is often disposed of instead of utilized to its fullest potential. With successful recovery of the fines and filler from the primary sludge, less raw material will be needed in the production of paper. This will decrease the cost of virgin material and the cost of disposing the sludge, while at the same time decreasing the volume of waste sent to landfills. Primary sludge was collected from a local paper mill and stored at the facilities of Western Michigan University. Solids and ash testing was done …

Population Dynamics In Response To Fire In Quercus Laevis - Pinus Palustris Barrens And Related Communities In Southeast Virginia, Allen E. Plocher
Biological Sciences Theses & Dissertations
Permanent plots in the Zuni Pine Barrens (Isle of Wight Co., Virginia) were sampled in order to: quantify plant population dynamics in response to fire, compare these dynamics among different moisture regimes, compare the effect of mechanical understory removal to that of fire on tree seedling and herbaceous dynamics, and determine the effect of dense lichen (Cladonia spp.) coverage on pine seedling establishment and survival. Fire resulted in 40% aboveground mortality in the overstory, 80% in the sapling/large shrub layer, and nearly 100% in the understory, followed by a 3.3 to 10.6 fold increase in understory density. Regeneration …
