Problems solved by technology

[0004] The purpose of the present invention is to provide a manufacturing method of sunflower straw wood-based panels, to overcome the deficiencies in the prior art that the strength of the panels is reduced due to the destruction of the fiber structure, a large amount of wood raw materials are wasted, the cost is relatively high, and they cannot be recycled.

Embodiment 1

[0015] (1) Firstly, all the sunflower stalk raw materials are split into two halves from the middle by the sunflower stalk peeling machine, and the thin skin on the shell and the inner white core of the sunflower stalk are peeled off by a pressure wheel and a mechanical brush, so as to become flat strips, the thickness of which is between 2mm-3mm, and the width is about 50mm;

[0016] (2) Five layers of paving are required to produce a 9mm thick veneer: First, lay a layer of unglued straw strips on the plank table as the first layer, that is, the bottom skin, and spread the double-sided glued straw strips on the The top of the first layer is used as the second layer and the direction of fiber paving is perpendicular to the first layer. Use unglued straw strips on top of the second layer as the third layer and the direction of fiber paving is perpendicular to the second layer. , Same as the first layer, use double-sided glued straw strips on top of the third layer as the fourth...

Embodiment 2

[0020] (1) Part of the sunflower stalk raw material is split into two halves from the middle by the sunflower stalk peeling machine, and the thin skin on the sunflower stalk shell and the inner white core are peeled off by a pressure wheel and a mechanical brush, so as to become flat strips;

[0021] (2) The production of 9mm thick veneer needs to be paved with five layers: put the veneer veneer through a single-sided gluing machine to make one side have glue, and lay the glue side up on the plank table to form the bottom skin and serve as the first layer. Use unglued straw strips on the top of the first layer of veneer as the second layer and the direction of fiber paving is perpendicular to the first layer, use a layer of veneer coated on both sides as the third layer, use unglued sunflower Straw strips are laid on top of the third layer as the fourth layer and the fiber laying direction is the same as that of the second layer, and the veneer glued on one side is laid face d...

Abstract

The invention relates to a method for manufacturing board with sunflower straw and is characterized in that the sunflower straw is processed into level strips and a layer of straw strips which is not gummed is laid on a board platform as a first layer; and then straw strips which are gummed are laid on the first layer in turn as a second layer to a fifth layer; the laying directions of neighboring fibrous layers are vertical to each other; the laid plate blanks are pre-pressed and hot pressed in turn and every layer of sunflower straw is condensed with urea-resin to be stuck as a whole and form straw plywood; the hot pressed plywood goes through processes of sander treatment, double sizing, laying okume face on both sides, hot press and cutting raw edges by a sawing machine in length and breadth after being cooled. The invention has the beneficial effect that fibrous structure is not damaged and the board strength is high; by adopting discarded sunflower straw as the raw materials, manufacturer could save wood, reduce cost and protect the ecological environment; in this way, the invention has high economical and ecological benefit.

Description

technical field [0001] The invention relates to the technical field of wood-based panels, in particular to a method for making a sunflower straw wood-based panel. Background technique [0002] Wood-based panels are generally divided into plywood, blockboard, particle board, medium-density board, and fiberboard. The existing wood-based panel technology is manufactured through various forms of deep processing of wood. For example, plywood is made of logs The cut section is processed into veneer veneer by rotary cutting machine, and after drying, it is glued, paved and hot-pressed by gluing machine; particleboard is made by crushing small-diameter wood and wood processing waste, planing into wood wool, and then It is made by drying, mixing glue, paving, hot pressing, edge sawing and sanding; the existing straw-based panel technology belongs to the particle board category, and generally wheat straw, rice straw and sugarcane straw are crushed, dried, mixed with glue, Paving, hot...
