The important position of epoxy glue in solid wood furniture

Gluing is the use of adhesive to firmly join the objects together. Gluing technology is widely used in modern industrial and agricultural production. Epoxy adhesive is a high-performance adhesive that cannot be separated from the production of solid wood furniture. It is produced in solid wood furniture. It occupies an important position. Gluing is the use of adhesives to firmly join objects together. Gluing technology is widely used in modern industrial and agricultural production. Epoxy adhesive is a high-performance adhesive that is inseparable from the production of solid wood furniture. It is produced in solid wood furniture. It occupies an important place.

There are many types of adhesives with different properties. Wood is a polar substance, and the adhesive is also a polar substance, so that the wood and the adhesive can be firmly bonded. Adhesives used in the wood industry account for approximately 60% of total adhesive production. Among the adhesives used in the production of solid wood furniture, epoxy emulsion, although not the largest, is the best and the most environmentally friendly.

The process of firmly joining two glued joints together with an adhesive is called gluing. The processes involved in the manufacturing of solid wood furniture, such as tenon joint, finger joint, veneer mold lamination, and jigsaw puzzles, are inseparable from gluing technology. . During the bonding process of solid wood furniture accessories, a series of physical and chemical changes have occurred on the surface of the wood, and a series of bonding theories have been formed after long-term research. Such as mechanical bonding mechanism, adsorption bonding mechanism, diffusion bonding mechanism, chemical bonding mechanism, chemical reaction between adhesive and adhered molecule to obtain high-strength primary valence bond, chemical bonding force is much larger than intermolecular force .

In the solid wood furniture bonding process, the chemical bonds between the adhesive and the adherend molecules, the surface treatment and the obtained active groups and the adhesive are mainly formed by the active groups and coupling agents in the adhesive and the glue. . . The above mechanisms can only reflect one aspect of the gluing phenomenon. In fact, the bonding of wood is the result of a combination of forces. Epoxy adhesives are one of the most effective adhesives due to their excellent properties. It has formed an important position in the production of solid wood furniture.
