Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing and case.

[0017] A wood veneer gluing method of the present invention includes the following basic steps: (1) veneer manufacturing: sawing the log into wood sections of a certain specification length, and then using a rotary cutter or a planer to cut the wood sections with or without softening treatment. Cutting machine and other processing into veneer, veneer thickness ranging from 1 mm to 6 mm; (2) Punching uses physical or mechanical methods to punch holes in the core board, the hole diameter is 0.1 mm to 1 mm, and the holes can be randomly The distribution can also be distributed according to certain rules. The holes are hollow or semi-permeable holes, and the shape of the holes is round, square, etc.; (3) Dry the veneer to a certain moisture content of 5% to 20%; (4) Glue coating According to the process requirements, the dried core board is glued, the glue amount is 10...

Abstract

The invention discloses a gluing method for a wood veneer. The wood veneer which is manually punched is used as a basic constitution unit and a to-be-glued object. The wood veneer is subjected to random or regular punching treatment along the thickness direction of the veneer by adopting the mechanical methods of drilling and punching or physical methods of laser drilling and microwave drilling, and the size, shape, depth and number of holes are not limited. The wood veneer which is subjected to punching is glued, the adjacent glue layers are connected together to form a three-dimensional reticular-layered glue layer composite structure, mechanical rivet force is formed, and the gluing strength is accordingly improved. Glue liquid penetrates into the wood veneer via the periphery of manually holes, and the body strength of the wood veneer is strengthened. A manufacturing method of the wood veneer comprises the following steps of (1) veneer manufacturing; (2) veneer drying; (3) veneer glue application; (4) assembly; (5) gluing; and (6) post treatment. The wood veneer manufactured by the gluing method has the characteristics of high gluing strength, good water resistance, high compressive strength and good size stability.

Description

1. Technical field [0001] The invention relates to a wood veneer gluing method. 2. Background technology [0002] Wood veneer gluing methods currently mainly include hot-press gluing and cold-press gluing. , soybean flour glue and blood glue, etc. The main products of wood veneer glue are wood plywood and laminated veneer lumber. [0003] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. [0004] The difference in physical and mechanical properties of plywood in the vertical and horizontal directions is small. Commonly used are three-ply board, five-ply board and so on. Plywood can improve wood utilization and is a major way to save wood. It can also be used as a material for aircraft, ships, trains, autom...
