The objective of this study was to improve interfacial adhesion properties at the interface of thermomechanical pulp (TMP) fiber and isotactic polypropylene (iPP) using thermoset adhesives such as phenol formaldehyde (PF) and urea formaldehyde (UF). This study also attempted to achieve fiber-to-fiber adhesion using thermoset adhesives before the molten iPP would flow into the fiber web. The fra...
Polyester resin plastination is a less expensive technique, resulting in high quality plastinates. The dissected poultry specimens were fixed with formaldehyde. Specimens were impregnated with resin, followed by curing resulted in good quality dry, odourless and solid specimens which can be used for teaching.
Approximately 1 million metric tons of urea-formal-dehyde resin are produced annually. More than 70% of this urea-formaldehyde resin is used by the forest products in-*This information was written and prepared by a U.S. Government employee on official time and it is, therefore, in the public domain and not subject to copyright.
A number of commercial panel products, primarily particleboard and hardwood plywood, were tested for their formaldehyde emission behavior using desiccator, perforator, and dynamic chamber methods. The results were analyzed in terms of the source of formaldehyde observed in the tests (free vs. hydrolytically produced) and the potential utility of the testa as product standards for boards in mobi...
A test chamber method was developed to provide a small and simple emission testing facility capable of testing construction products over a range of climatic parameters, such as temperature, ventilation rate and air velocity, that could be varied independently around typical indoor values. Volatile organic compounds (VOCs), specifically the aromatic hydrocarbons fraction, were measured using a ...
The objective of this study was the evaluation feasibility producing particleboard for general use using cotton gin waste generated in Argentina and urea formaldehyde resin. chemical composition size distribution particles ginning residue as well mechanical physical properties particleboards obtained were investigated. Density flexural strength produced with varying levels urea-formaldehyde res...
