Water And Water Vapor Barriers For Structural Plywood : Ii. Core Void Fillers For Structural Plywood., James Van Dyck Fear Sep 1947

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. …

High Temperature Coatings., Irvin Henry Lutz Jun 1947

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.

A Substitute For Wood Veneer., Edwin R. Arbegust Jun 1947

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.

The First Approximate Conditions For The Formation Of Mesomorphous Coacervates., Stanley H. Jury 1916-1983 Jan 1947

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 …
