Method for manufacturing small-diameter wood integrated material planed thin sheet

Abstract

The invention relates to a manufacturing method of small-diameter wood glulam slicing veneers and a leveling drying device. Small-diameter wood, tended wood, inferior wood or cordwood produced in thecutting and manufacturing process, and the like which are not easily efficiently used are softened by a composite agent by being infused with pressure, and then after flitches are integrated by fingerjoining and obliquely slotting the wood with a moisture-curable type adhesive, the flitches are sliced into wet veneers, and the wet veneers are then sent to a special continuous high-temperature ironing leveling dryer to be leveled and dried into sliced veneers in the clamping of upper and lower steel belts. The invention integrates a series of special technologies and transforms small-diameterwood which is not easily used into sliced veneers which meet requirements of various technical specifications with very wide application ranges. Low-grade wood is fully used, which improves the addedvalue of products and comprehensive utilization efficiency of forest resources. The invention has the advantages of simple and reasonable technique method, low equipment cost, good product quality, broad development prospects and the like. Significant social and economic benefits can be produced after the implementation.

Description

technical field [0001] The invention relates to a method for manufacturing veneer and improvement of equipment, in particular to a method for manufacturing small-diameter laminated wood sliced ​​veneer, which belongs to the field of wood processing. Background technique [0002] The flake-like material produced by planing and processing the log of high-quality and precious tree species with large diameter as raw material is called "natural veneer". After the fast-growing and large-diameter logs are peeled or sliced ​​into veneers, they are processed and glued into wooden squares, and then sliced ​​into veneers of various colors and textures, which are called "artificial veneers". [0003] Since the 1960s, research on artificial veneer has begun abroad. By the mid-1980s, our country also used a large number of artificial veneer veneer plywood purchased from Japan, Hong Kong and other places for interior decoration, and many colleagues also carried out The research and improv...

AI Technical Summary

Problems solved by technology

There is a fundamental difference between plantation wood and natural forest wood. Plantation wood generally has small diameter grades, high inclusions, and larger microfibril angles than natural forest wood. Most of the sawn boards have pith cores. Or close to the pith center, the growth stress is large, easy to deform and warp, the material is relatively soft, etc., and cannot be directly used as high-grade materials such as furniture and interior decoration, which restricts the use range of plantation wood and affects its economic value

In particular, small-diameter wood, tending wood, low-quality wood, or short wood produced during harvesting and processing have not been efficiently utilized for a long time, and there have been no successful reports of using them to make sliced ​​veneer
