Whether in the home or enterprise plywood can be said to be everywhere, we will find similar appearance of plywood quality is very different.
In the production of plywood almost every process in varying degrees of impact on plywood plywood quality, let's look at what is affecting the quality of plywood.
1, adhesive quality The performance of the performance of the adhesive synthetic resin adhesive, the composition of the coordination and the glue-regulating process and other several square surface. In recent years, the domestic plywood with glue and glue adjustment process to carry out a lot of research work, which not only saves a lot of chemical raw materials, reduce product costs, so that product performance has also improved, which is the performance of technological progress.
In the production of only the use of synthetic resin performance is good, there is sufficient adhesive strength, adhesive distribution ratio is reasonable, the catalyst out of the performance of stable, resin content and viscosity is appropriate, there is a long period of activity to ensure that normal operation and product indicators meet the requirements.
2, single board quality The quality of single plate, especially its surface state, has a great influence on the strength of glue.
Single board quality in the wood section preparation and single-plate spin-cutting processes should be enough attention, to be good wood softening treatment, control the conditions to make the single board indicators in the best value, at the same time should pay attention to the water content and flatness of the single board.
3, plywood plywood Before the glue pressure should pay attention to master the amount of gel application and slab aging two links. The amount of glue is too large, the cost is high, and the glue layer is too thick, the internal stress increases, and the glue is easy to penetrate the glue, the amount of glue is too small, is not conducive to the glue immersion, the glue layer will be incomplete. The length of aging should be appropriate and change reasonably with climate change. In order to achieve the whole sheet of the core plate, reduce the core plate stacking, leaving the seam. Pay attention to master the glue bar zhong, pressure reduction speed, especially in the slab more moisture more attention should be paid.
