摘要
以竹展平板为基本单元制造定向重组竹集成材的工艺方法.将竹展平板涂布间苯二酚树脂胶黏剂,涂胶量为200～300 g/m2,按照竹青面对竹青面、竹黄面对竹黄面的方式进行组坯,热压加工制成展平竹层积材,再采用指接的方式进行接长,获得性能优异的定向重组展平竹集成材,产品的尺寸规格一般为长1000～3500 mm,宽50～300 mm,厚60～150 mm.指接时相邻层板的指接接口需错开组坯,在常温下冷压4～5 h,冷压压力为1.0～1.5 MPa,后固化养生.
Abstract
This paper introduces a process method of manufacturing thedirectional flattened bamboo glulam with flat-tened bamboo boards as the basic unit.Resorcinol resin adhesive was applied to the flattened bamboo boards with the amount of glue for 200～300 g/m2.Flattened bamboo boards were assembled and hot pressed into flattened bamboo laminates,arranged in a bamboo green to bamboo green and bamboo yellow to bamboo yellow orientation.After finger-joining,directional flattened bamboo glulam with excellent performance was obtained,and the dimensions of the product are generally 1 000～3 500 mm in length,50～300 mm in width,and 60～150 mm in thickness.When finger-joining,the joints of adjacent layers need to be staggered.The cold pressing process was carried out at room temperature for 4～5 h at a pressure of 1.0～1.5 MPa,followed by curing and recuperation.
