Problems solved by technology

[0006] The tension of the core board, front panel and back board cannot resist the deformation caused by the stress of the core strip. Although the current woodworking technology solves the problem of flatness, as time goes on, the fiberboard will absorb the moisture in the air. Greatly affects the durability of furniture made from it

Embodiment 1

[0019] A production process of environment-friendly woodworking plywood is characterized in that, comprises the following steps:

[0020] (1) Log pretreatment: Cut the logs into 8mm thick wool boards with a rotary cutter, and dry them for 13 days until the moisture content is 13-15%;

[0021] (2) Pressing and planing to remove burrs: Plane the dried rough board into slabs with a specified thickness, remove the burrs from the slabs, and cross-cut both ends to form a square plate with a thickness of 5-7mm;

[0022] (3) Adhesive making: mix by weight ratio of raw glue: flour: wood flour: bentonite = 1: 0.08: 0.05: 0.6, wherein the raw glue is composed of 20% formaldehyde, 35% urea, 30% ammonia water , a mixture of 10% polyvinyl alcohol and 5% melamine, the temperature is controlled at 75°C, stirred for 30min, and set aside;

[0023] (4) Finished product: The above square plate is used as the upper and lower panels and the middle core plate made of the board skin and the short ma...

Abstract

The invention discloses a production technique for an environment-friendly wood plywood. The production technique for the environment-friendly wood plywood includes steps that (1) pre-processing log; (2) planning and burring to form square plates; (3) preparing adhesive for latter use; (4) using the square plates as an upper panel, a lower panel and a middle core plate, bonding adhesive, hot pressing to form a base plate, and sanding to obtain a finished product. The production technique for the environment-friendly wood plywood uses slab and short and small material as the raw material of the plate core, the slab and short and small material are combined through special adhesive, and the produced core plate is large, flat in surface, difficult to deform and low in production cost. When preparing adhesive solution, flour, wood powder, bentonite and the like are added to decompose free formaldehyde, and the environment protection is realized. The production technique greatly improves the outturn percentage, simplifies the technique, improves the product use intensity and quality and has broad market prospect.

Description

technical field [0001] The invention belongs to a production process of woodworking boards used in the furniture and decoration industries, and particularly relates to a production process of an environment-friendly woodworking plywood. Background technique [0002] The object processed by the woodworking machine is wood. Wood is the earliest raw material discovered and utilized by human beings, and it is closely related to the living, traveling and use of human beings. Humans have accumulated rich wood processing in long-term practice experience . Woodworking machine tools are developed through people's long-term production practice, continuous discovery, continuous exploration and continuous creation. [0003] The quality of woodworking craftsmanship is directly related to the quality of the entire construction effect, but with the improvement of building materials product technology, many woodworking projects have been directly customized by manufacturers, whic...
