Density and Hot Pressing Influences on Properties of Laminated Bamboo Sliver Lumber
During common hot-pressing process for making laminated bamboo sliver lumber,slabs are input and taken usually at a relatively low temperature condition,which ensures the product quality,however extend the production period.To shorten the production cycle for laminated bamboo sliver lumber,the authors studied the hot-pressing method at a higher temperature condition for slabs inputting and taking.The results showed that under the given conditions,hot-pressing temperature had a significant influence on lumber modulus of elasticity,modulus of rupture,thickness swelling and horizontal shear strength;and the lumber density and hot-pressing time affected thickness swelling greatly.When density was 1.0 g/cm3,hot-pressing time was 1.5 min/mm and hot-pressing temperature was 145,1,55 ℃,the properties of laminated bamboo sliver lumber met the requirements of LY/T 1072-2002 for laminated bamboo strips lumber and GB/T 20241-2006 for laminated veneer lumber.
