Bamboo fiber bundle plywood production technology

Abstract

The invention relates to a bamboo fiber bundle plywood production technology, which comprises the following production steps: obtaining fresh bamboo raw material, removing green, splitting, removing yellow, bamboo joints and diaphragms, rolling, obtaining bundle bamboo long fiber, drying, cutting, gumming, drying, forming and paving, hot pressing, longitudinally and transversely sawing, checking, trimming plywood sides, rechecking and accepting and warehousing finish product. The technology is simple, the utilization ratio of the bamboo material is high, the production cost is low, the internal bonding strength of the produced bamboo plywood is higher, the production density is adjustable, the plywood surface strength is high, the bamboo fiber bundle plywood can be widely used as building templates, carriage bottom plates, decoration materials, furniture materials and the like, and the bamboo fiber bundle plywood is a high-performance building decoration engineering material.

Description

technical field [0001] The invention relates to a production process of bamboo fiber bundle plywood, which belongs to the production technology of plywood produced by the wood-based panel industry. Background technique [0002] my country is very rich in bamboo resources. At present, we are vigorously promoting forest protection and green activities. Bamboo resources with a short growth cycle have naturally become an alternative raw material for the country to save timber resources. Yet most of the bamboo plywood produced on the market at present makes the utilization rate of bamboo not high because of the reason of craft, and the amount of waste is large. Moreover, because of the production process, the manufacturing density of bamboo plywood is high, and it is almost impossible to use nails for processing. Therefore, it is almost impossible to use in civilian households. Most of them can only be used in low-grade use environments such as building templates. High-quality b...

Problems solved by technology

[0004] In addition, the invention patent CN1387981A discloses a method for manufacturing recombined bamboo plywood, which uses bamboo as raw material, and produces plywood through processes such as cutting, rolling, drying, dipping, drying, billeting, and hot pressing. The inner diaphragm and bamboo yellow of the bamboo joints are not removed, which will cause major problems in the quality of plywood gluing, and the hot pressing process of cold in and cold out will also consume too much energy, resulting in high production costs.

The diameter of the bamboo fiber after rolling by this process can be known from the description of its assembly and paving that the diameter of the bamboo fiber is too large, which is not conducive to the redistribution of the fiber structure and the full filling of the gap when pressing the board.

Invention patent CN101186046A discloses a kind of bamboo laminated board and its processing method. Its processing method is: rolling, drying, dipping, drying, laminate laying, pressing and curing processes. The major defects of bamboo green, bamboo yellow, and bamboo inner diaphragms that have not been removed will also seriously affect the bonding strength of plywood, which will cause major quality risks in the product
