Liquid Agglomeration Of Ink Particles In Deinking, Timothy J. Bowen

Paper Engineering Senior Theses

Liquid agglomeration is defined by references as a separation process (3). For the purpose of this thesis project, it is the process of using a hydrocarbon oil, dispersed in water, to a pulp slurry, to agglomerate the ink particles and then float them to the top. The idea behind this research is that the sludge produced will have a higher BTU value due to the hydrocarbon oil, which will make incineration a more feasible means of disposal. The preliminary work consisted of determining whether or not the ink particles would agglomerate with hexadecane. It was found that the ink particles …

Repulping Bottle Carriers, Mahsa Khosravani

Paper Engineering Senior Theses

Wet strength resins are used to enhance the strength of the paper in the presence of water and high humidity. Paper makers have a difficult time breaking down the wet strength resins which are used to aid in this process. The ideal situation would be to have high wet strength and still be able to brake it down easily. Unfortunately wet strength paper keeps its integrity because of the chemistry involved in its preparation. The chemistry that protects the structure of the high wet strength paper will also defend it in the pulper. The problem that causes the main concern …

Electrokinetic Dewatering Of Softwood Furnishes, Aaron R. Redman

Paper Engineering Senior Theses

Enormous quantities of water are required in the preparation and formation of paper products. One of the most costly operations in paper manufacture is removal of excess water from the sheet and disposal of by-products from paper production. Currently, high steam energy is necessary in the drying process of paper manufacture. Disposal of a paper by-product, sludge, is also a rising concern due to environmental risks, shrinking landfill space, and rising disposal costs. Both production costs and disposal costs could be reduced with a more effective and efficient process to enhance water removal in paper production and sludge disposal.

The Effects Of Recycling On A Never-Dried Softwood Kraft Pulp Beaten To Different Initial Freeness Levels, Heath A. Smith

Paper Engineering Senior Theses

The objective of this study is to compare two different pulps, a softwood kraft pulp with a groundwood pulp, to see if there is any difference in the behavior of their sheet properties as they are recycled. Neither pulp was dried before the experiment began. The pulps were each refined to three different freeness levels to determine the effect of initial freeness on recycled sheet properties. Tests for tear, tensile, zero-span tensile, opacity, brightness, scattering coefficient, absorption coefficient, and porosity were performed on the sheets in order to determine the effects of recycling on those sheet properties. A Kajaani fiber …

Treating Recycled Papers With Naoh For Strength Improvement, Satoshi Suga

Paper Engineering Senior Theses

Loss of strength is one of the worst aspects of recycled papers. Even though several factors are responsible for this phenomenon, loss of fiber swelling and inter fiber bonding are believed to be the main contributors. Therefore, prevention of loss in swelling and inter fiber bonding of recycled pup should result in the minimum strength loss of recycled papers.

Chemicals with hydroxyl group such as NaOH are known to provide superior swelling power to.pulp, and their swelling power might be utilized to minimize the strength loss of recycled paper.

In this study, batches of bleached kraft paper were repulped at …

A Study Of The Effect Of Recycling On The Bonding Ability And Characteristics Of Fines, Lon E. Pschigoda Ii

Paper Engineering Senior Theses

The recycled paper industry has seemingly grown faster than the technology to go along with it. It has become accepted that along with paper recycles comes a certain amount of strength loss, limiting the uses of secondary fiber. If the recycling industry is continued to grow an effective counter to this strength loss needs to be found. In order to counteract this strength loss the mechanism must first be better understood. The three mechanisms that will be focused on for this paper will be 1) The loss of fiber length, 2) Hornification, and 3) The decrease in surface bonding activity. …

Improving Print Quality In Wallpaper By Pigment And Latex Substitution, Christopher L. Stratton

Paper Engineering Senior Theses

The coated paper industry is rapidly changing and improving. Because of increasing demands by consumers, high quality paper at the lowest possible price is at a premium. Because of this paper makers and coaters are continually looking for ways to improve their sheet without increasing cost.

This experiment was designed to test the role which pigment and latex has in influencing the final sheet quality. This was tested in two stages. The first stage examined pigment variations and the second latex variations. In the pigment variation trial, a number 1 high brightness clay was replaced by a structured clay pigment. …

Repulping Bottle Carriers, Jennifer A. Giver

Paper Engineering Senior Theses

The primary object of this thesis project was to repulp post consumer bottle carriers with the addition of chemical reagents and mechanical shear. Recycling bottle carriers is difficult to achieve due to the chemical additives that are added to the pulp. Chemical additives introduced to the virgin pulp are wet strength resins.

Post consumer bottle carriers used in this experiment contained Kymene 557, which is a wet strength product produced by Hercules incorporated and is difficult to repulp due to the cross-linking employed by this chemical additive. This experiment utilized both oxidizing and reducing chemical reagents such as hypochlorite and …

Strength Properties Of Steam Exploded Laser Printed Papers, Dhamodharan Srinivasan

Masters Theses

The mam objective of this study was to investigate the effect of steam explosion pulping on the strength properties of recycled fibers. The properties considered were zerospan tensile strength, tensile breaking length, tensile stretch, tensile energy absorption, scott bond and pentosan content. This study also examined the important operating parameters that affect the properties. Laser printed waste paper was pulped by the steam explosion process. The experiments were statistically modeled to cover the various process variables. Chemical addition, residence time, pressure, and dispersant level were varied during the steam explosion experiments. Chemical addition was kept at four levels and other …
