Water And Water Vapor Barriers For Structural Plywood : Ii. Core Void Fillers For Structural Plywood., James Van Dyck Fear

Electronic Theses and Dissertations

This thesis presents the results of an investigation conducted to improve the weather resistance of plywood assemblies used in prefabricated housing manufacture. Specifically, this work involved water sealers for edge joints (called edge sealers), the prevention of surface transfer of water vapor through plywood (called vapor barriers), and fillers for structural defects in the wood (called core void fillers). Two edge sealers for plywood were developed that were considered successful in resisting water permeation. One was a quick drying paint formulated by the addition of 30 per cent leaded zinc oxide to 70 per cent Arco primer paint No. 156. …

A Substitute For Wood Veneer., Edwin R. Arbegust

Electronic Theses and Dissertations

This thesis is a report of an investigation for a substitute for wood veneer to be used as face material for wire-bound boxes. The fiberboard substitute was made using a heavy paper backing with a wood waste mixture of chips and sawdust with various types of adhesive binders. The following adhesives were used singly and in mixtures: Starch, sodium silicate, asphalt emulsion, animal glue, urea resin with a wheat flour extender, rosin, and casein. The composition and test results of the fiberboard panels made in the laboratory are reported.

High Temperature Coatings., Irvin Henry Lutz

Electronic Theses and Dissertations

This thesis is a report on coatings exclusive of the porcelain enamels which may be used at temperatures as high as 750*F., and also a description of the properties of the more heat resistant resins of commerce. The method of preparation and testing of the various coatings investigated in this research is given, and the results are tabulated and discussed. Best results were obtained with Dow Corning silicones of the 800 series heavily pigmented with either zinc dust or aluminum bronze, and with glycerol phthalate -- silicone coatings pigmented with aluminum bronze.

The First Approximate Conditions For The Formation Of Mesomorphous Coacervates., Stanley H. Jury 1916-1983

Electronic Theses and Dissertations

An analysis of the literature shows the close analogy between liquid crystalline phases in solution (fluids separating from main portion of solution and having some of the directional properties of crystals) and unipolar coacervates (solvated micelles of like charge separating as a distinct colloidal phase). A theory is here advanced that liquid crystalline phases in solution are the direct result of a maximum in osmotic pressure which is predictable from the first approximate equation of the Debye-Huckel theory in the same manner as unipolar coacervates were predicted by I. Langmuir. Application of the theory to aqueous soaps, investigated by Vold …

The Surface Impregnation Of Wood : Ii. Use Characteristics Of Impregnated Wood : Iii. Investigations Of Resin Adhesives., John V. Birkel

Electronic Theses and Dissertations

This thesis is divided into three parts: I. The Surface Impregnation of Wood; II. Use Characteristics of Impregnated wood; and III. Investigations of Resin Adhesives. The material presented in Part I is a continuation of previous experimentation that had established general methods for producing a hardened surface wood product. The methods involved parting of the wood fibers on the surface by a special serrating tool, followed by a surface impregnation and final curing. This section presents work carried on to determine the optimum conditions for serrating and subsequent impregnation. The effect of species on impregnation. and the impregnation of unfinished …

Improved Techniques For Washing Iron Blue Suspensions : Ii. The Preparation Of O, O'-Dichlorobenzidine From O-Chloronitrobenzene., Marvin L. Gernert

Electronic Theses and Dissertations

I. IMPROVED TECHNIQUES FOR WASHING IRON BLUE SUSPENSIONS

The investigation of several procedures for the speeding of the washing of iron blue suspensions to remove electrolytes is reported. The use of several techniques to coagulate blue particles in the colloidal range to cause more rapid settling was found to be of little value. A conventional Oliver filter and centrifugal clarifier were found to be unsatisfactory for clearing iron blue suspensions. Considerable advantage in washing by settling and decantation was obtained with the settling of the blue suspensions in relatively shallow vessels. A continuous washing procedure was developed whereby the blue …

Ethylcellulose Lacquer Coatings For Polystyrene Plastics., Stuart V. Heil

Electronic Theses and Dissertations

An ethylcellulose lacquer system for both decorative and protective purposes was developed for use on polystyrene plastics. It was found that a one-coat lacquer containing only alcohol solvents produced the most satisfactory finish. Formulations were based on experimental work, conducted to determine the effect of the various lacquer components on the plastic. The results of a study of formulations on a two-coat system are presented.

A Graphical Solution For Batch Steam Distillation Of A Binary Mixture., Howard D. Carlson 1921-

Electronic Theses and Dissertations

The theory for the graphical solution of batch steam distillation of a binary mixture is presented and illustrated. The results obtained from this graphical procedure are compared with actual experimental results. The comparison showed very close agreement between the graphical results and the experimental results. Three sets of experimental data are shown for benzene-bromobenzene mixtures and one complete set for benzene-toluene mixtures.

Surface Impregnation Of Wood : Ii. Gaseous Impregnation Of Wood : Iii. Investigations On Submarine Decking : Iv. Investigation Of Marine Adhesives., Otto J. Mileti

Electronic Theses and Dissertations

This thesis presents results on methods used to produce a hard surfaced wood product. The methods involve the parting of the wood fibers on the surface by a special serrating tool, followed by surface impregnation and final curing. The serrations on the wood surface produce an artificial grain upon curing. A preliminary investigation was made to improve the rot-resistance of wood by gaseous treatment. Results of such treatments show some limited success with formaldehyde on yellow poplar and warrant further study. An investigation was made to find a substitute for teak wood used on submarine decking. A number of combinations …

Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.

Electronic Theses and Dissertations

A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates …

The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel

Electronic Theses and Dissertations

Ethylcellulose was refluxed with Stearic, Oleic, Linseed Fatty acids, and a neutral Mineral Oil in the presence of a solvent. The products recovered were analyzed to determine if any possible reaction had taken place. Conditions for the reaction were carried out so that the temperatures obtained could be in the near range of varnish cooking, that is between 375 and 500°C. The I solvents used were diethylbenzene, boiling point 180oC and tetralin, boiling point 208oC. In each case approximate stoichiometric proportions of the fatty acids and ethylcellulose were used. These were refluxed to a sensible minimum viscosity of solution. The …
