Before the pressure of plywood should be careful to grasp the amount of sizing and slab aging two links. The amount of glue is too large, the cost is high, and the adhesive layer is too thick, the internal stress increases, together with a brief glue, the amount of glue is too small, not conducive to the gel, the adhesive layer will not complete. The length of aging should be suitable, with reasonable changes in climate change. To complete the core board, reduce the core plate laminated, off the seam. Should be careful to grasp the glue layering, pressure, especially in the slab of water more should be careful.
In addition, the selection of new technologies, equipment, such as the use of high-efficiency Jet single-board dryer, core plate sewing machine, core plate leveling machine, finished sizing, billet, pre-pressure, hot-pressing operation, the use of mechanized loading and unloading, quick closure Hot Press, can accurately control the process conditions, so that product quality is more assured.
It is embodied as the function of adhesive resin adhesive, the coordination of each component and the blending process, and so on several side mites. In recent years, the domestic plywood with the various components and sizing process to do a lot of research work, which not only save a lot of chemical raw materials, reduce the cost of products, so that the product function has also improved, which is the embodiment of technological progress.
In the production of only the use of synthetic resin function is excellent, there is a satisfactory bonding strength, the distribution of adhesive groups than reasonable, the modulation of the adhesive function is stable, resin content and viscosity suitable, have a satisfactory long active period of talent to ensure normal operation and product policies meet the requirements.
