The effect of finger length and adhesive type on the curing time of finger-jointed black pine (Pinus nigra L.) lumber

Popis výsledku v původním jazyce

Finger-joint is a technological process that uses small-dimension and low-quality lumber to obtain high-quality structural wood products. Curing time of an adhesive consists one of the most important factors on the final performance of finger-jointed wood. In this study, finger-jointed black pine (Pinus nigra L.) specimens were prepared to investigate the effect of finger length and adhesive type on the curing time of these assemblies, as specified by their static flexural properties. Two adhesive types (an emulsion polymer isocyanate and melamine-urea-formaldehyde adhesives), two finger lengths (12.5 and 20.0 mm) and four curing times (2.5, 7, 24 and 168 h) were used for this purpose. Statistical analysis results showed that finger length and curing time had a statistically influence on the bending behaviour of single finger-joint specimens. The necessary handling strength was attained between 7 and 24 h for the 12.5 mm specimens, while the 20.0 mm length finger-joints could be further processed after 2.5 h.
