An investigation was made to determine the feasibility of electrostatically spraying adhesive on strands and veneer for the purpose of improving adhesive bonding efficiency. If electrostatic spray treatment could improve coverage uniformity on the composite product compared to conventional spray application, then theoretically bond strength should improve, allowing for adhesive quantities normally required for production to be reduced. Estimates for a 5% reduction in the annual adhesive requirement for an OSB mill producing 300 million square feet on a 3/8" basis amounts to a $300,000 saving. Tests carried out at Forintek examined the fundamental interactions between charged water spray and strands and veneer to determine whether coverage characteristics could be improved. Laboratory set-ups included fitting Forintek's lab blender with electrostatic spray equipment and a vertical tube assembly for investigating charged spray interaction with free-falling strands. Since most commercial applicators spray free-falling strands within a blender, our first objective was to investigate how strand coverage would be effected within such an environment. Test results showed that coverage on strands electrostatically treated within the blender was not significantly different than non-charged applications. This was probably due to the free-falling strands not being adequately grounded when treated. These results are consistent with theory which states that targets should be grounded for spray coverage improvement to occur. To further test this theory, using a vertical plastic tube apparatus, individual strands were tethered by a fine ground wire and then allowed to free-fall through a charged spray, resulting in dramatic increases in coverage compared to uncharged tests. Although grounding strands within a blender may at present be unpractical, methods for momentarily grounding the strands within the blender should be investigated. Also, alternatives for applying adhesives within a blender, that allow for proper strand grounding, should be considered. Following spray tests with OSB, tests were conducted to treat veneer with electrostatic spray. A 50/50 mixture of resin and water was electrostatically applied to veneers and results showed that although coverage was improved, both in uniformity and quantity, the size of drops was considerably smaller that what is recommended for optimum bonding. In theory, to apply a charged spray consisting of larger drops would significantly reduce the effects of electrostatic forces on droplet trajectory and therefore, further tests to apply resin to veneer were discontinued.
