Abstract
The present invention relates to plywood for container floors and a production method. The plywood is hot pressed after a plurality of layers of wood single boards are overlapped; the single boards are taken out after fully soaked in glue, and dried until the moisture content is 6% to 12% by microwave drying technology. The production method adopts the combined technology of single board soaking glue and microwave dryness, and thus, the density of the single boards is effectively enhanced. The plywood can adopt common wood species as raw materials to produce and process container floors of which the quality and the properties accord with the international industry standard of container wood bottom boards. Therefore, the plywood achieves the purpose of replacing natural woods by artificial woods, protecting ecological environment and reducing production cost.
Description
Technical field
The present invention relates to the production method of composite board for bottom board of container, specifically relate to a kind of production method that adopts artificial forest wood to make composite board for bottom board of container.
Background technology
In recent decades, along with container industry flourish in international modern transportation, the container bottom board industry is also more and more prosperous, but has also brought the transition of tropical hard wood to fell.International environmental protection organization and country in Southeast Asia begin the to adopt various measures felling and the outlet of restriction log.So seek reproducible artificial environmental protection woods is that raw material are main outlets of container bottom board industry sustainable development.
Artificial forest, as willow, pine, larch, clone's wood is soft, density is low, adopts traditional floor manufacturing method for material, with the veneer drying after the rotary-cut, cloth glue, precompressed, hot pressing, its product strength does not reach instructions for use.There is technology to relate to veneer is carried out the impregnation processing, and then dry, the method can improve intensity really, but because traditional guipure, roller drier adopt steam drying, the temperature height, from outside to inside with veneer drying, it is glued that the veneer surface is produced, the crack.
Summary of the invention
At the defective of prior art, the purpose of this invention is to provide a kind of production method of composite board for bottom board of container, the technology that the method adopts impregnating glue of veneer to combine with microwave drying.Adopt this method, can be with artificial forest, as pine, poplar, larch main raw material(s); solve cracking, glued problem that veneer drying occurs; replace natural wood to produce container bottom board thereby reach, reduce production costs the purpose of preserving the ecological environment with artificial wood.
For achieving the above object, the technical scheme of the present invention's solution is:
A kind of production method of composite board for bottom board of container comprises the steps: at least
A) rounding being become thickness is 1.5～2.0 millimeters veneer;
B) with the wet veneer after the rotary-cut or rotary-cut after the veneer of super-dry is completely infused in the glue, the solid weight degree of glue is 5%～30%;
C) take out the impregnation veneer, adopt the microwave drying technology drying, moisture content is controlled at 6%-12%;
D) moisture content is met the requirements of an amount of glue of a part of double spread in the veneer, cloth glue amount be the 250-400 gram/square metre;
E) according to the size of the glued board that will produce, the veneer of cloth glue not and the veneer that has been coated with glue are stacked alternately to predetermined thickness, and the formation blank flat of at room temperature colding pressing;
F) under 120-150 ℃ temperature,, continued to exert pressure 35-60 minute to apply the pressure of 1.2-1.8MPA pressure through the blank flat of colding pressing;
G) plate after the hot pressing is carried out cutting edge, sanding, mortise, get product.
In the inventive method, described impregnation mode can be the open type impregnation, vacuum tank pressure glue dipping, any one in the drum extrusion impregnation; Described dipping glue can be any one in phenol glue, modified urea-formaldehyde glue, the melamine glue;
Described dry back veneer is preferred: glue application amount 300-360 gram/square metre, under 120-135 ℃ temperature, the blank flat of colding pressing is applied the pressure of 1.4-1.6MPA pressure, continued to exert pressure 35-45 minute.
Adopt the production method of aforesaid composite board for bottom board of container of the present invention, by combining of impregnating glue of veneer and microwave drying technology, effectively improved veneer density, eliminate thermograde and moisture gradient in the dry run, moisture content is discharged from inside to outside simultaneously, avoid the veneer cracking to greatest extent, improve veneer utilization rate, product strength, enlarge the purpose of the raw-material scope of application thereby reach.
Below in conjunction with drawings and Examples the present invention is described in further detail.
