Method for producing float laminated blank assembly of bamboo strand lamination

Abstract

The invention belongs to bamboo artificial plate and composite material technique field. The steps of the invention includes: preparing bamboo strip, thin bamboo strip, bamboo thread and bamboo thread bundle of different level from bamboo, preparing uniform bamboo bundle from bamboo strip, thin bamboo strip, bamboo thread and bamboo thread bundle of quantitating, fixing grade, staggering node, reversing head and trail, constituting uniform bamboo layer unit from quantity determined uniform bamboo unit, immersing bamboo layer unit in glue solution for scheduled time and taking out, putting bamboo layer unit in float tank to constituting uniform single layer blank, glue trickling and drying glue-dipped bamboo layer unit, prepressing glue-containing bamboo layer unit for constituting blank to slice shape blank, constituting laminated blank from multi-layer slice shape prepressing material by stated direction, level and quantity, heating and compressing laminated blank in mould to preparing thin bamboo strip and bamboo thread laminated material. The excellence of the invention is simple, removing curtain weave process, capable of constituting multilayer thick blank one time, improving quality of blank assembling, reducing process steps and cost, and improving bamboo utilization ratio and bamboo performance.

Description

technical field [0001] The invention belongs to the technical field of bamboo wood-based panels and composite materials. Background technique [0002] There are many bamboo processing enterprises in our country, producing various products such as bamboo wood-based panels and bamboo flooring. The main method is to process bamboo into some basic units, including bamboo slices, bamboo strips, and bamboo threads, and then make various types of bamboo products through gluing. [0003] The production process of bamboo laminated lumber (bamboo plywood) is to make bamboo strips into bamboo strips, then weave them into bamboo curtains, dip in glue, assemble blanks, and press them. The basic unit of the billing method of bamboo curtain assembly is the number of bamboo curtains. In order to obtain more bamboo curtains, the thickness of bamboo strips at all levels should be as thin as possible, and the range of change is small. Due to the thin thickness of the bamboo strips, the surfa...

AI Technical Summary

Problems solved by technology

However, the current bamboo curtain assembly method has poor uniformity, high cost, and labor-intensive composition, which cannot meet the requirements of high-performance bamboo laminated lumber, and requires a new process route.
