The effect of synthesis variables on composition and reactivity of phenol-formaldehyde resins

Creator:: Parker, Robert John
Abstract:: This research related resin synthesis variables of phenolformaldehyde resins to their chemical content and reactivity. The study was part of a larger project correlating resin properties to their performance as plywood adhesives. Formaldehyde-to-phenol and Na0H-to-phenol mole ratios were examined within the ranges used commercially. I also examined various proportions of...

Measuring adhesive cure by dielectric analysis

Creator:: Rubitschun, Robert Allen
Abstract:: Present methods of determining proper glueline cure are inadequate in either production or laboratory situations because they are time consuming and "after the fact". Monitoring the glueline while the wood composite is still in the press would provide many advantages over existing methods. Such a system would provide greater control...

Gluability of platen-dried Douglas-fir veneer

Creator:: Sandoe, Michael Dean
Abstract:: This study was undertaken to determine whether Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) veneer could be platen-dried and then sucessfully glued into two-ply parallel-laminated panels. A range of veneer thicknesses, platen temperatures and final dry moisture contents were examined. Thicknesses included were nominal 0.1, 0.2, 0.3 and 0.4 inches; platen temperatures...

Determining appropriate accelerated aging tests for keruing plywood

Creator:: Wilkie, George Robert
Abstract:: The main objective of this study was to determine appropriate accelerated aging methods for exterior plywood made with Southeast Asian hardwood face veneers. A secondary objective of this study was to determine the durability of exterior plywood made with keruing (12 Dipterocarpus spp.). To reach these objectives I made plywood...

Wetting as a predictor of surface inactivation for platen dried Douglas-fir veneer

Creator:: Kadlec, Kim Michael
Resource Type:: Masters Thesis

Bonding wood particle composites with foamed adhesive

Creator:: Watters, Allan Eugene
Abstract:: The quality and cost of wood particle composites are substantially determined by how the adhesive that bonds the composite is distributed on the particles. Distribution of the adhesive is controlled by the method of application. Currently the adhesive is applied by spraying it onto the particles. It was hypothesized that...

Effect of wood extractives on cure of phenolic resin

Creator:: Nguyen, Dong
Abstract:: Difficulties have been encountered in gluing some Southeast Asian woods using phenolic resin. Extractives in veneers from the trade groups yellow, white, and red meranti (Shorea, Parashorea, and Pentacme spp. ), keruing (Dipterocarpus spp. ), and kapur (Dryobalanops spp. ) were suspected to be able to modify resin cure and...
