In the production and manufacturing of the woodworking industry, the use of adhesives is essential. From a technical perspective, using woodworking adhesive can perform processes such as splicing, assembly, vacuum membrane wrapping, veneering, and repair on the board.
Simply put, the rational use of woodworking adhesive products can showcase wood in a completely new style. However, in actual production, furniture manufacturers need to pay attention to what they need to pay attention to when using woodworking glue. Let me share this with you below.
Pay attention to the details of temperature when using woodworking glue
In different seasons, it is important to measure the working environment temperature and wood surface temperature on time. Normally, the difference in temperature to some extent determines the speed of the curing reaction time of woodworking adhesive.
For example, in the summer when the temperature is relatively high (ambient temperature greater than 35 ° C), water-based splicing adhesive will cause the reaction time of the adhesive with hardener to accelerate, and the curing time will also be accelerated.
Therefore, we recommend using the mixture within 30 minutes (the faster it is used, the better), and workers should also put in pressure tools as soon as possible after applying glue to avoid surface conjunctiva that may affect the final bonding effect; On the contrary, in winter when the temperature is relatively low, the use time of the mixed panel adhesive can be extended to 60 minutes before use.
When using woodworking glue, pay attention to the details of wood moisture content
Furniture manufacturer workers inevitably have to face the issue of wood moisture content when using woodworking adhesive to bond wood. Therefore, after natural moisture is regained, the moisture content of generally dried boards should be controlled between 8% and 12% for optimal results.
When the moisture content of the substrate is less than 8%, it may cause excessive permeability of the substrate, allowing all adhesive to be absorbed into the board, resulting in a lack of adhesive on the bonding surface and cracking.
On the contrary, if the moisture content of the substrate is too high, it may lead to poor adhesive permeability, inability to form adhesive nails in the board, incomplete cross-linking reaction, and may also cause the phenomenon of adhesive opening.
When using woodworking glue, pay attention to the details of the base material itself
The condition of the substrate itself, if the preliminary work is not done well, will also lead to the final bonding effect of the glue. For example, if the board is not polished and polished, it will cause depressions on the surface of the wood, and glue is applied to it, resulting in a lack of glue at that location and no bonding strength.
Therefore, before using woodworking glue, you need to ensure that the surface of the substrate is smooth and free of insect holes. The right angle accuracy of the base material is good. The bonding surface should ensure that there are no “planing marks, saw marks, charring” and other phenomena. It is strictly prohibited to use adhesive. The joint surface is bonded to substrates contaminated by grease, dust, etc.
The above are some basic details that wood processing manufacturers need to pay attention to before using wood glue. I hope it will be helpful to everyone.
