Manufacturer Technology of Dense Chinese Fir Laminated Veneer Lumber (LVL)
Abstract
Dense Chinese Fir LVL was manufactured from Chinese Fir veneer which was impregnated with laboratory prepared water soluble phenol formaldehyde(PF) resin. The influences of various processing factors on properties of dense Chinese Fir LVL were explored. It is showed that the mechanical properties of dense Chinese Fir LVL first increase and then decrease with the increase of drying temperature and hot-pressing time. Plank performance becomes higher with the increase of compressibility and hot-pressing temperature. The optimum technological parameters for LVL process are set.
