Abstract

The invention belongs to a manufacturing method for plywood bamboo nail plates. The method comprises the steps of bamboo collecting, sawing and cutting of bamboo culm, bamboo tubes fragmenting, bamboo strip processing, fixed-length processing of bamboo chips, drying, gum dipping and gum draining of bamboo chips, drying of gum drained bamboo chips, assembling in stagger joint, jointing of pre-assembled unit width, hot briquetting, plasma treatment, layer spinning and so on. The method can be used for manufacturing the plywood bamboo nail plates with continuous length, devisable width and classified performances; the method enlarges the range of application of bamboo, the manufactured plywood bamboo nail plates can meet the requirements of engineering materials, the plywood bamboo nail plates have great tightness and soundness and excellent performances, cracking does not occur after the plywood bamboo nail plates are used for a long time, and the quality is good.

Description

technical field ： [0001] The invention belongs to a method for manufacturing glued bamboo layer nail boards, and belongs to the technical field of bamboo wood-based boards and bamboo engineering materials. Background technique ： [0002] my country is rich in bamboo resources. With the processing and utilization of bamboo resources in recent years, the bamboo-based panel industry has begun to take shape. Various products such as bamboo flooring, bamboo plywood, and recombined bamboo have been marketed and created a large number of social and economic benefits. . The engineering of bamboo materials is still in its infancy, and glued bamboo is one of them. [0003] The original design of the glued bamboo was based on a series of methods of American engineered wood. Engineered Wood System in the United States is mainly engineered wood (Glulam) and structural composite wood (Structural composite Wood). It is different from other engineered wood mainly in its standardized ...
