Building templates are very common in the use of buildings, and the construction time of a construction project determines the quality of the used building templates.In use, what are the reasons that affect plywood building templates?

1. Single board quality

The surface state of the veneer has great influence on the bonding strength.In wood with veneer quality and rotary cut veneer enough attention, each process have to be timber softening process is very good, good control lathe cutting conditions make the veneer each index in the optimal value, at the same time should pay attention to the moisture content of veneer and smoothness.

　　2. Glued plywood

Before gluing, attention should be paid to two parts: sizing amount and slab aging.Too much glue, high cost;Moreover, the adhesive layer is too thick, and the internal stress increases.The amount of glue is too small, which is not conducive to the infiltration of glue and liquid, and the rubber layer will be incomplete.The aging time should be appropriate and change with climate change.To achieve core plate integrity, reduce core plate lamination, seam separation.It is important to master the secondary and lower pressure speed of the glue bar, especially the more water in the billet.

3. Adhesive quality

The results showed that the performance of synthetic resin adhesive, the coordination of various components and the blending process of several square mite surface.In recent years, domestic plywood by rubber components and rubber process a lot of research work, this not only save a lot of chemical raw materials, reduces the product cost, make the products performance is also improved, this is a sign of technological progress.Only used in the production of synthetic resin performance is good, have enough bonding strength, adhesive group distribution ratio is reasonable, modulation of adhesive performance is stable, the resin content and viscosity is appropriate, have long enough active period to ensure the normal operation and products the indicators meet the requirements.

Pay attention to the reasons that affect the building template in the use process, so as to improve the overall efficiency of the construction project!
