摘要
以制材、干燥、实木产品加工生产之间内在联系和影响为主要原理,对直径为14—24cm的3等柞木原木分别采用制材-干燥-纵剖(SDR)SE艺和传统加工工艺生产集成材进行对比试验。两面下锯法提高了毛边板出材率和生产率,有效控制了毛边板的干燥变形。结果表明:与传统加工工艺相比较,刨光材等级率未降低的情况下,SDR工艺提高了原木到集成材木材利用率5.41%。
This paper describes that the production tests of domestic laminated boards from small-diameter( 14- 24 cm)and low-grade(grade 3)oak logs using the techniques of SDR and convention, respectively, according to the principle of the internal connection and impact among sawing, drying and further processing solid products, as well as related theoretical basis. Living sawing increased the lumber recovery factor and production rate and effectively controlled the drying deformation of flitch. The results of production tests indicated that the technique of SDR increased the wood utilizing percent from log to laminated board by 5.41%, compared to the technique of convention, under the condition of the planed lumber grade yield being not decreased.
